In the vast land that stretches in different parts of the world, have you ever found a place with very low air humidity?
Perhaps the first thing that comes to mind is the deserts of the Middle East. However, did you know that similar ecosystems can also be found in Asia, even in Indonesia?
Yup, in addition to deserts, there are other ecosystems that also have low air humidity, namely steppes. Unlike the savannas, which are still covered with several types of trees, the steppes are dominated by grasses and shrubby plants without the conspicuous presence of trees. It is these conditions that make the steppes known as vast and dry grasslands.
Citing National Geographic, the steppes only receive about 250-500 millimeters of rainfall per year. This low and uneven amount of precipitation makes the vegetation in the steppes limited.
To understand more about this unique ecosystem, check out the following explanation of the definition, characteristics and types of Steppes!
According to Kamus Besar Bahasa Indonesia (KBBI), a steppe is a vast and dry flat land, which is only overgrown with shrubs. Steppes can also be defined as vast grasslands.
Meanwhile, according to Britannica, the term “steppe” comes from the Russian language, which means “flat grassy plain”. This ecosystem is widely found in temperate regions, such as the United States, Siberia, Tibet, China, and several regions in Indonesia. Generally, steppes are located far from the sea and are in the vicinity of mountains. This geographical condition causes the air humidity to tend to be low or dry.
In general, the average temperature of the steppes in East Asia ranges from 25°C in summer and can drop to -15°C in winter. Meanwhile, the steppes in the European region have more stable temperatures, with an average of no more than 20°C in summer and about 0°C in winter.
Steppes are also known as transitional biomes between wet climates and dry climates. Its low air humidity makes this ecosystem not dry enough to be a desert, but also not fertile enough to be covered with trees in large quantities.
Low and uneven rainfall in the steppes greatly affects the type of flora that can grow in these ecosystems. Generally, steppe vegetation is dominated by various types of grasses, shrubs and shrubs no more than 50 centimeters high.
Some specific examples of plants that are able to survive in this windy and semi-arid environment include feather grass (Nasella tenuissima) and needle grass (Andropogon aciculatus).
In addition, some other plants commonly found in the steppes include:
The climate and humidity of the air in the steppes play a role in determining the characteristics of the flora living in them. Most of the plants in these meadows have a solid body structure and are able to adapt to extreme climatic changes from season to season.
During the dry season, some plants may produce fewer flowers as a survival strategy. Meanwhile, there are also types of plants that are precisely able to adapt to low humidity conditions and thrive when there is less rainfall.
The presence of faunal species in the steppe biome is strongly influenced by the type of flora or vegetation that grows in the steppe. In other words, the flora and fauna that inhabit the steppes coexist in an ecosystem that supports each other.
Short grass vegetation in the steppes becomes an ideal habitat for various large mammals, such as:
In addition to these mammals, reported by Animalia, some other fauna commonly found in the steppes include:
Among the list of fauna above, there are several ferocious predators that inhabit the steppes, such as leopards, wolves and foxes. Their presence is inseparable from the presence of herbivorous mammals that are the main prey.
These relationships form a natural food chain, which ensures that the balance of the ecosystem is maintained.
Although they are both grassland ecosystems, steppes have a fundamental difference from savannas. The main difference between them lies in the type of vegetation. The steppes are inhabited only by short plants and shrubby plants, while the savannas have a few tall trees scattered over long distances.
Here are some of the characteristics of the steppe biome that distinguish it from other ecosystems:
Steppes can be found in different parts of the world, such as the United States, Siberia, Tibet and China.
One of the largest and most famous steppes in the world is the Eurasian Steppe, which stretches from Eastern Europe to Central Asia, covering the territory of Ukraine, Russia, Kazakhstan, Turkmenistan, Uzbekistan, Xinjiang (China), Mongolia and Manchuria.
Based on climatic conditions, steppes can be divided into three main types, each of which has different characteristics depending on the level of precipitation, temperature and geographical location:
The tropical steppe is an intermediate region between a wet tropical climate and a dry tropical climate. The main characteristic of tropical steppes is the higher annual rainfall compared to steppes located in temperate or subtropical regions.
However, despite being wetter, these steppes still have less fertile soil characteristics and a predominance of vegetation in the form of grasses and shrubs.
Temperate climate steppes receive up to 500 millimeters of precipitation per year. One of the main characteristics of these steppes is the extreme change in temperature between summer and winter. In summer, temperatures can rise significantly, while in winter, temperatures can drop dramatically to near freezing.
Subtropical steppes generally have higher and more evenly distributed rainfall than temperate steppes. This region tends to experience more moderate temperature changes and has slightly higher air humidity than the rest of the steppes.
As one of the large-scale ecosystems on Earth, the steppe has several supporting components that maintain the balance of its ecosystem. Here are the main components that support life in the steppes:
Autotrophic organisms are living beings that can produce their own food through the process of photosynthesis, taking advantage of sunlight, water and carbon dioxide. In Steppe ecosystems, autotrophs play the role of the main producers that become a source of food for other organisms.
Examples: grasses, shrubs and various types of plants typical of the steppes.
Heterotrophic organisms are living things that cannot make their own food and therefore must consume other organisms to survive. In Steppe ecosystems, heterotrophic organisms act as consumers, both as herbivores (plant eaters) and carnivores (predators of other animals).
Examples:
Abiotic components are non-biological environmental factors that greatly affect the life of living beings in the steppes. These factors create conditions typical of the steppes that are dry, windy and have extreme temperature changes.
Examples:
Decomposing organisms or decomposers are living things that decompose the remains of dead organisms as well as waste products from other organisms. The presence of decomposers is essential in the recycling of nutrients, so that organic substances can return to the soil and favor the growth of vegetation in the steppes.
Examples:
Besides being found in the United States, Siberia, Tibet, and China, steppes can also be found in Indonesia, you know!
One area that has a steppe ecosystem is East Nusa Tenggara (NTT), especially on the island of Timor. There, you can see vast expanses of grasslands and various steppe grass-eating animals cultivated by the local community.
Although not as popular as Savanna, the steppe biome still has a unique natural charm and is often used as a tourist destination. Its vast landscape with typical grass vegetation and the diversity of large mammals are its main attractions. The beauty of the steppes is no less amazing than other ecosystems.
So, are you interested in exploring the beauty of the steppes and feeling the atmosphere of a different nature?

The world of flora has a variety of unique and interesting plants, one of which is mosses or bryophytes. This plant can be found in various places, such as rocks, walls, cliffs, and soil. Although often overlooked, lichens actually play an important role for the environment and humans.
According to Mountain Moss, Moss is able to absorb rainwater like a sponge. This ability helps prevent flooding as well as maintain soil moisture, making it a plant that plays a role in ecosystem balance.
Moss also has benefits for the medical world. For example, liverwort(Hepaticopsida) can be used as a medicine for hepatitis C because it contains antiviral compounds. Later, peat moss (Sphagnum) could be used to treat acne, hemorrhoids, and skin diseases.
For more details, let's see the definition, characteristics, types, and functions of the following moss plants!
Bryophytes (bryophytes) are small plants that do not have transport vessels (Xylem and phloem) to drain water and nutrients. In other words, Moss absorbs water directly through the surface of its body. These plants generally live in humid environments, such as rocks, cliffs, walls, tree trunks, and soil.
Mosses are autotrophic, which means they can produce their own food through the process of photosynthesis with the help of sunlight. In contrast to flowering plants, mosses do not produce flowers or seeds. Instead, mosses reproduce using spores.
Although it is more commonly found in damp places, Moss can also grow in less wet environments. This is due to the presence of a waxy cuticle layer that envelops its body, thereby reducing excessive evaporation.
One of the unique things about lichens is their different structure from vascular plants. Lichens do not have true roots, stems and leaves, but rather simple structures that perform similar functions.
Lichen consists of several main parts, namely:
Lichens have unique characteristics that distinguish them from other plants. These plants belong to The Division Bryophyta in the kingdom Plantae and are known as small plants that do not have transport vessels to drain water and nutrients.
Here are the general characteristics of moss plants:
Generally, lichens are classified into three types, namely liverworts (hepaticopsida), hornworts (anthocerotopsida), and mosses (bryopsida):
Liverwort is a type of Moss in the form of a flat sheet with many grooves, resembling The Shape of a heart. According to Nacademy, liverworts are considered the most primitive type of lichen.
This plant usually grows in humid environments, such as tropical rainforests, as well as on rocks or soil near water sources such as rivers and lakes.
Some examples of common liverwort species include:
Hornwort got its name because it has an elongated sporophyte resembling a horn. This plant is usually found in damp and shady places, such as rocks, soil, ditches, river banks, or lake shores.
Characteristics of hornwort:
Some examples of hornwort species that are often found include:
Mosses are the largest group of mosses compared to other types of mosses. This type is found in humid environments, such as forests, swamps, and plantations. Mosses can grow on a variety of surfaces, such as soil, rocks, wood, even a little in the water.
Characteristics of mosses:
Some examples of common lichen species include:
In addition to acting as small plants that decorate rocks or moist soil, mosses also have important functions in ecosystems and human life. Here are some of the main functions of lichens:
Mosses act as pioneers in ecosystems, being the first plants to grow in environments that do not yet have vegetation, such as rocky areas or arid lands. Mosses help form the soil layer by breaking down rocks and retaining moisture, allowing other plants to grow.
Moss has a sponge-like ability to absorb rainwater. With this property, Moss helps reduce the risk of flooding as well as keeping the surrounding soil moist.
With their ability to retain water and cover the soil surface, mosses help prevent erosion caused by wind or rainwater. This is especially important in hilly areas or soil prone to landslides.
Lichens become a living space for various microorganisms, small insects and invertebrates. Some small animals make it a shelter and a source of food.
As autotrophic plants, mosses perform photosynthesis, which means they absorb carbon dioxide (CO₂) and produce oxygen (O₂). Thus, lichens help maintain the balance of gases in the atmosphere.
Some types of lichens contain compounds that are beneficial to human health. For example. liverwort (Hepaticopsida) contains antiviral compounds that are used as hepatitis C drugs. While peat moss (Sphagnum) has antiseptic properties that are used in the treatment of wounds, acne, and skin diseases.
Peat moss (Sphagnum) is often used as a growing medium in agriculture and horticulture because it can absorb and store water well. Some mosses also play a role in the manufacture of perfumes and natural coloring materials.
Mosses may seem like small plants that are often overlooked, but their role in ecosystems and human life is enormous. As pioneer plants, mosses help shape the soil, absorb water, prevent erosion, and provide habitat for a variety of organisms. In addition, Moss also has benefits in the medical, industrial, and agricultural fields.
The presence of mosses contributes to maintaining the balance of the ecosystem as a whole. Therefore, it is important for us to understand and preserve this plant so that its benefits can continue to be felt by future generations. By getting to know more about Moss, we can better appreciate its role in everyday life.

Have you ever noticed green plants with unique, curled leaves when they were young? That's Ferns!
In addition to beautifying the environment, these plants also have an important role in the ecosystem. Unlike flowering plants, ferns reproduce using spores and are able to grow in a variety of habitats, from damp forests to stone surfaces. Not only that, some types can even be consumed and used as traditional medicine.
Curious about the uniqueness and benefits of ferns? Let's go deeper!
Ferns (Pteridophyta) are a group of vascular plants that reproduce through spores.
These plants are better known as ferns or ferns and are often found in a variety of environments, from tropical rainforests to Home yards. Some common examples of ferns that are easily found around us include Clover (Marsilea), suplir (Adiantum), and pole Ferns (Cyathea contamans).
According to the National Museum of the Philippines, Ferns have various benefits for humans and the environment. Here are some of the main uses of ferns:
According to Sandy et al. (2016), Indonesia has about 1,300 species of ferns, making it one of the countries with the highest diversity of ferns in the world. Meanwhile, based on data from the Natural History Museum, there are about 13,000 species of ferns in the world, so that about 10 percent of the world's fern species grow in Indonesia.
With various benefits and roles in the ecosystem, Ferns are one of the important plant groups to be preserved.
At first glance, Ferns look similar to seed plants because they have true roots, stems, and leaves.
However, this plant has unique characteristics that distinguish it from other plants. One of the main characteristics of ferns is their way of reproduction, which does not use seeds or flowers, but spores.
Here are some characteristics of ferns:
According to the Natural History Museum, there are about 13,000 species of ferns in the world. Some types of ferns are able to grow and survive in a variety of environments and different climatic conditions. Therefore, Ferns are grouped into several types based on certain aspects.
Here is the classification of ferns:
By the size of the leaves, ferns are divided into two types:
Ferns are also classified by the shape and size of their spores, which are:
Judging by the function of the leaves, ferns are divided into two types:
Based on the arrangement of their leaves and spores, Ferns are grouped into four main classes:
Ferns generally grow in shady and humid environments, such as tropical rainforests, rock crevices, and around water sources. This plant can be found attached to tree trunks, soil surfaces, rocks, and even in water.
According to the Aakash Institute, some types of ferns are able to adapt to more extreme environments, such as sandy soils. An example is the Horsetail (Equisetum debile), which can survive in soils with low moisture content.
More specifically, the habitats of ferns include:
Ferns have two ways of reproducing, namely vegetative reproduction (asexual) and generative reproduction (sexual). In addition, ferns also undergo metagenesis, which is the cycle of rotation of offspring between the sporophyte and gametophyte phases:
Vegetative reproduction in ferns occurs in the absence of fusion of sex cells. The main way of vegetative reproduction in Ferns is through stolons or rhizomes (internodal underground stems).
These stolons will produce gemma (buds) which then develop into new plants.
Generative reproduction occurs through the fusion of male and female sex cells. The mechanism is as follows:
In addition to reproducing vegetatively and generatively, ferns also undergo metagenesis, which is the rotation of offspring between two phases:
According to Gramedia Blog, the principle of metagenesis in various types of ferns - both Homosporous Ferns, Heterosporous ferns, and transitional Ferns—has the same pattern.
Ferns (Pteridophyta) are a group of vascular plants that reproduce using spores. With a unique structure, these plants have true roots, stems, and leaves and undergo rotation of offspring (metagenesis). The variety of species of ferns allows them to grow in a variety of habitats, from moist forests, tree trunks, to sandy soils. In addition, Ferns have various benefits, both as ornamental plants, foodstuffs, traditional medicines, and ecological roles in maintaining ecosystem balance.
With its adaptability and various benefits, Ferns are one of the important plant groups for the environment and human life.
Therefore, the existence of ferns needs to be preserved so that the ecosystem remains balanced and the benefits can continue to be enjoyed by future generations.

Have you ever imagined having your own garden?
Perhaps what comes to mind is a beautiful flower garden, a lush vegetable garden, or an orchard full of crops. No wonder, because the three types of plants have a myriad of benefits, both for personal consumption and high economic value if sold.
In the world of agribusiness, one type of plant that is of high economic value is seed plants (Spermatophytes). Because seed plants can be used as food, medicine, clothing, ornamental plants, and industrial raw materials.
Interestingly, seed plants are not only limited to fruits that produce seeds, but also include ornamental plants, food-producing plants, and fiber-producing plants for the clothing industry.
Want to know more about seed plants? Come on, check out the definition, characteristics, classification, benefits, and reproductive system below!
Seed plants or Spermatophytes are a group of plants that have organs in the form of seeds as a means of reproduction. The term Spermatophyta comes from the Greek, namely sperm which means 'seed' and phyton which means 'plant.'
Seeds act as the main structure in the reproduction of seed plants. This seed is formed from the development of the embryo that is inside the ovule after the fertilization process takes place.
Seed plants have a very wide diversity and are not limited to fruit-bearing plants alone. Citing data from Harvard University BioNumbers, there are about 352,000 species of seed plants in the world, with the majority coming from the group of angiosperms or flowering plants.
In Indonesia, seed plants play an important role in various sectors, ranging from food, clothing, medicine, decoration, to industry. Based on a report from the National Research and Innovation Agency (BRIN), there are about 40,000 species of seed plants that grow in Indonesia.
Interestingly, this figure covers about 9 percent of the total species of seed plants in the world, making Indonesia one of the countries with the highest biodiversity. Some examples of typical Indonesian seed plants include:
Seed plants (Spermatophytes) have a more complex structure compared to other plant groups such as mosses (bryophytes) and ferns (Pteridophytes). Its body part consists of clearly distinguishable roots, stems and leaves.
However, because seed plants are of various types, many people are still often mistaken in distinguishing them from other plant groups. To understand more deeply, here are the general characteristics of seed plants:
From the above characteristics, it follows that seeds are the main characteristic that distinguishes seed plants from mosses and ferns. In addition, another advantage of this plant is that it has a more complex network of vessels, which are the xylem and phloem.
The presence of this network of vessels allows seed plants to grow larger and stronger than plants that do not have a network of vessels, such as mosses.
Seed plants (Spermatophytes) are divided into two large groups, namely gymnosperms (open seed plants) and angiosperms (closed seed plants).
Gymnosperms are a group of seed plants whose ovules are not protected by fruit leaves or pericarp. Therefore, it is referred to as an open-seeded Plant. The word gymnosperm itself comes from the Greek, namely gymnos which means 'naked' or 'open.'
Characteristics of gymnosperms:
Angiosperms are a group of seed plants that have flowers as a means of generative reproduction. In contrast to gymnosperms, the ovules in angiosperms are protected by the ovules, which later develop into true fruits.
Characteristics of angiosperms:
Seed plants (Spermatophytes) have a high economic value and provide various benefits to humans. This type of plant is used in many sectors, such as food, medicine, decoration, clothing, industrial materials, to environmental preservation.
Seed plants are the main source of food for humans, both as staple foods, vegetables, and fruits. Some crops such as rice, corn, wheat, and sago are staple foods for most of the world's population.
In addition, various vegetables such as tomatoes, cabbage, potatoes, carrots, kale and spinach are rich in vitamins, proteins and fiber that are beneficial to health. Some grains such as jackfruit seeds, basil seeds, and pine seeds can also be consumed or processed into food.
Meanwhile, fruits such as mango, apple, guava, passion fruit, watermelon, Sapodilla and Cherry are not only delicious but also rich in antioxidants and nutrients that are good for the body.
Many seed plants contain active compounds that are useful in medicine. One of them is cloves, which are known to relieve pain, reduce inflammation, and have antibacterial properties.
Coriander is often used to help launch the digestive system and maintain heart health. In addition, ginkgo has long been used in traditional medicine to improve the cognitive function of the brain and relieve migraines and other headaches.
In addition to being useful as food and medicine, seed plants are also often used as decorations and ornamental plants to beautify rooms, parks, and landscapes.
Several types of plants such as Hajj Ferns, cypresses, and cacti are often used to decorate homes and gardens because of their unique and aesthetic shapes. In addition, flowers such as roses, hibiscus, daisies, and sunflowers are also very popular as ornamental plants because of the beauty of their attractive colors and shapes.
The textile industry also relies heavily on seed plants as raw materials for the manufacture of fabrics and clothing. Cotton is the main material in the manufacture of cotton fabrics used in the clothing industry around the world. In addition, the fibers from the hemp plant are also widely used in the production of high-quality fabrics that are strong and durable.
Seed plants are also utilized in a variety of industries, from the cosmetics industry to papermaking. Wood from various types of seed trees, such as pine and Acacia, is often used as a raw material for papermaking.
In addition, plant oils and fats such as palm and Olive are widely used in the cosmetic, pharmaceutical and food industries. The sap produced by some types of trees such as rubber is used as a raw material in the rubber industry that produces various products such as tires, gloves, and medical equipment.
Wood from seed plants also plays an important role in the construction industry and furniture making. Teak wood is known as a very strong and durable material, so it is often used for the manufacture of furniture and buildings. In addition, mahogany wood is also often used in the manufacture of wooden floors, cabinets, and various high-quality furniture products.
In addition to providing economic benefits, seed plants also play an important role in maintaining ecosystem balance and environmental sustainability. Plant roots help prevent soil erosion and reduce the risk of flooding and landslides.
In addition, seed plants also function as carbon dioxide absorbers (CO₂) and produce oxygen (O₂) through the photosynthesis process, thus contributing to reducing global warming. The presence of seed plants also helps maintain biodiversity by providing habitat for various species of animals and microorganisms.
Seed plants can reproduce in two ways, namely generatively (sexually) and vegetatively (asexually). Both of these methods allow seed plants to multiply and maintain their viability in a variety of environments.
Generative reproduction in seed plants occurs through the flower, which serves as the main reproductive organ. This process begins with the formation of male cells (pollen grains) and female cells (stigma).
The process of generative breeding involves two main stages:
Plants that reproduce generatively produce seeds that can later grow into new plants. Examples of seed plants that reproduce generatively include rice, corn, guava, cucumber, bark, mango, tomato, and papaya.
Vegetative reproduction occurs without going through the process of pollination and fertilization. This reproduction is carried out by vegetative organs such as shoots, rhizomes (rhizome roots), or stolons (creeping stems).
Some examples of natural vegetative reproduction mechanisms in seed plants include:
Plants that reproduce vegetatively can grow faster than plants that reproduce generatively because they do not require the process of pollination and fertilization. Examples of seed plants that reproduce vegetatively include bananas, bamboo, breadfruit, potatoes, and duck cocor.
Seed plants play an important role in human life and ecosystems. With a wide variety of species and benefits, this plant is not only a source of food, medicine, clothing, and industry, but also contributes to maintaining environmental balance.
In addition, the reproductive system of seed plants, which includes both generative and vegetative reproduction, allows them to constantly develop and adapt to various natural conditions. Understanding the characteristics and benefits of seed plants can help us manage natural resources more wisely, so that their existence is maintained for future generations.

Have you ever stepped on the ground that feels soft, wet, even slightly swaying? If so, chances are you're in the thick of it!
This land is not just an ordinary wetland, but an ecosystem rich in organic matter and has a crucial role in maintaining environmental balance.
From storing huge amounts of carbon to being home to rare species, peatlands hold many interesting facts that are rarely known. However, behind its tremendous benefits, this ecosystem also faces serious threats due to human activities.
Let's take a closer look at what peatlands are, how they are formed, and why their preservation is so important to our lives!
According to Wetlands International, peatland is a type of wetland that has a watery soil layer and is composed of dead plant material that undergoes a slow decay process.
Meanwhile, Kamus Besar Bahasa Indonesia (KBBI) defines peatland as land formed from litter, wet plant residues, or rotting puddles and undergoes a very slow decomposition process.
Peatlands are formed through the accumulation of organic matter derived from decaying plant remains over thousands of years. This process occurs in waterlogged environments, such as swamps, river basins and coastal areas.
Menurut buku Creating and Restoring Wetlands (Second Edition) karya Christopher Craft (2022), lahan gambut dapat terbentuk dari berbagai jenis vegetasi, termasuk lumut gambut (Sphagnum), tumbuhan herba, serta vegetasi berkayu.
Because it is formed in an oxygen-poor environment (anaerobic), the organic matter in peat does not decompose completely. The decomposition process, which proceeds very slowly, leads to the accumulation of a large amount of organic matter, thereby forming a thick layer of peat.
Peatlands are classified into several types based on location, formation environment, maturity, fertility, and depth.
Coastal peat forms around coastal areas and is affected by sea tides. This type of peat gets additional minerals from sea water, so it has unique characteristics compared to other types of peat. The dominant vegetation in this area is mangrove forest.
Inland peat is formed far from the coastline and is affected only by rainwater. Unlike coastal peat, this type does not receive mineral enrichment from the sea. Vegetation growing on inland peatlands is dominated by broadleaf Woodlands.
As the name implies, transitional peat is formed between the coastal and inland areas. This type has characteristics that are a combination of coastal peat and inland peat, both in terms of soil composition and vegetation growing on it.
Topogenous peat is formed in areas of basins or lakes that are directly above mineral soils. The process of its formation is influenced by river water runoff and sea tides.
In contrast to topogenous peat, ombrogen peat is formed mainly due to precipitation without significant influence from river or sea water. This type of peat is commonly found in regions not far from the coast.
Sapric peat is the most mature type of peat. The organic matter in it has undergone complete weathering so that its origin is difficult to identify. The color of this peat varies from dark brown, gray, to black. In texture, sapric peat is smoother than other types of peat.
Fibric peat is peat that is still young and has not undergone complete weathering. The original material can still be easily identified. The structure of fibrous peat is dominated by coarse fibers with a brown tint.
Hemic peat is a type of semi-mature peat, where some of the organic material has been weathered but there are still parts that can be recognized. The texture is somewhere between Fine sapric peat and coarse fibrous peat. The color of hemic peat is generally Brown.
This type of peat has a high fertility rate because it is rich in minerals, bases and nutrients. Eutrophic peat is often found in areas that receive mineral supplies from river water or sea tides.
Mesotrophic Peat has a moderate fertility rate, with a mineral and alkaline content that is not very high but still sufficient to support vegetation growth.
Oligotrophic peat is the least fertile type of peat because it is poor in minerals and nutrients. This type is generally found in areas that only get water supply from rainfall, without additional minerals from other sources.
Peatland that has a thickness of between 50-100 cm. This type can generally still be used for agriculture with certain management techniques.
Peatland with a thickness of between 100-200 cm. This type of peat begins to contain thicker organic matter and requires special treatment if it is to be used for agricultural or plantation activities.
Peatland that has a thickness of between 200-300 cm. This type stores more carbon and tends to be more susceptible to degradation if dried or used unsustainably.
Peatland with a thickness of more than 300 cm. This type has a very high organic matter content and plays an important role in global carbon storage. Very deep peat should still be preserved to maintain ecosystem balance.
Peatlands have unique characteristics from other lands. The characteristics of peatlands are as follows.
Peatlands have an important role in maintaining the balance of ecosystems and human life. Here are some of the main functions of peatlands:
Peatlands serve as the world's largest absorber and store of carbon. A thick layer of peat contains organic matter that has not yet been completely decomposed, so it is capable of storing large amounts of carbon. If peatlands are damaged or burned, the stored carbon will be released into the atmosphere in the form of greenhouse gases such as carbon dioxide (CO₂) and methane (chī), which can accelerate climate change.
Peatlands act as natural sponges that absorb and store large amounts of water. Its ability to regulate water helps reduce the risk of flooding during the rainy season and maintain the availability of water during the dry season.
Peatlands are home to a wide variety of flora and fauna, including rare and endemic species such as orangutans, Sumatran tigers, and hornbills. In addition, peat ecosystems also support the growth of various types of typical plants, such as ramin (Gonystylus bancanus) and jelutung (Dyera costulata).
For people living around peatlands, this ecosystem is a source of livelihood, both through non-timber forest products (such as rattan and forest honey) and environmentally friendly fishing and farming activities.
Peatlands have the ability to filter water naturally by retaining pollutant particles and maintaining groundwater quality. This helps to keep water sources clean for ecosystems and humans.
In coastal areas, peatlands serve as natural fortifications that help prevent seawater from entering the mainland. This is important to maintain the balance of freshwater ecosystems and prevent agricultural land degradation due to salinization.
Peatlands have a very important role in maintaining ecosystem balance, storing carbon, regulating the water cycle, and being a habitat for various flora and fauna. In addition, peatlands also support the lives of surrounding communities by providing natural resources of economic value.
However, threats to peatlands, such as land conversion, fires, and unsustainable draining, can lead to serious environmental impacts, including increased greenhouse gas emissions and loss of biodiversity. Therefore, the preservation and wise management of peatlands is needed so that the benefits can continue to be felt by future generations.
By understanding the function and importance of peatlands, it is expected that awareness of efforts to preserve this ecosystem will increase, both at the individual, community, and government levels.

Waste is a serious problem that is not only a national responsibility, but also a global challenge that is still being resolved.
Based on Circular Letter (SE) Number 1 of 2025 concerning the commemoration of National Waste Care Day (HPSN) 2025, data from the Global Waste Management Outlook 2024 notes that around 38 percent of waste in the world is still not managed properly. This condition contributes greatly to three major environmental crises known as the Triple Planetary Crisis, namely climate change, biodiversity loss, and environmental pollution.
At the national level, Indonesia recorded a waste dump of 56.63 million tons in 2023. Of this total, only 39.01 percent or about 22.09 million tons were successfully managed. The rest, which is 60.99 percent or about 34.54 million tons, has not received adequate handling.
As part of the commemoration of HPSN 2025, Yayasan Initiasi Alam Rehabilitasi Indonesia (YIARI) initiated environmental clean-up activities with children in Ketapang regency, West Kalimantan. This action aims to instill environmental awareness from an early age, and invite people to be more concerned about waste management around them.
Curious as to what activities are carried out? Come on, check out the excitement of yiari's action with the children in Ketapang below!
In commemoration of National Waste Care Day (HPSN) 2025, Yayasan Initiasi Alam Rehabilitasi Indonesia (YIARI) together with children in Ketapang regency, West Kalimantan, held a clean-up action at seven different locations. This activity lasted for two days, namely on February 21 and 22, 2025.
Right on February 21, coinciding with the commemoration of HPSN, the activity began with a garbage clean action with students of SDN 20 Pangkalan Jihing, which is also part of the Gunung Tarak work site.
Still on the same day, YIARI held a waste recycling activity at the Sir Michael Uren Learning Center (LC SMU). In this activity, YIARI collaborated with Genta (nature lovers movement) from SMKN 1 Ketapang, creating an educational moment about Creative Waste Management and utilization.
In addition, YIARI also held an environmental clean action with children in Nusa Poring Village, which is part of the Melawi site project.
On February 22, the clean-up action continued in three elementary schools and one village, namely SDN 33 Cali, SDN 14 Pulau Cempedak, SDN 07 Hulu Sungai, and Batu Lapis Village.
The clean-up action initiated by Yayasan Initiasi Alam Rehabilitasi Indonesia (YIARI) in Nusa Poring Village received a positive response from the local community. This activity is part of a series of commemoration of National Waste Care Day (HPSN) 2025.
According to Dieka Pertiwi, education and awareness manager of YIARI, garbage cleaning activities are actually not new for children and residents in Ketapang Regency. Similar actions have become routine activities carried out in various villages.
'Actually, this clean-up action is not a new activity. Activities like this have been routinely done. So, HPSN is only ceremonial, because outside of festive moments like this, clean-up activities have become a regular agenda in the villages,” explained Dieka.
Furthermore, Dieka explained that in the framework of HPSN 2025, YIARI held a garbage clean action with a more ceremonial approach and involved a number of schools in the Ketapang area.
'The response from the community is very positive, especially from children who are used to participating in this activity regularly every month,” he added.
One of the interesting facts about clean-up activities in Ketapang Regency is the habit of children who make environmental care actions as part of their daily play activities. In some areas, such as in Mentatai, children often swim or dive in the river while picking up garbage they find on the surface and bottom of the river.
“They, if they see garbage at the bottom of the river, immediately taken. It has become a habit” ' said Dieka.
He added that this awareness is the result of various educational activities and environmental care actions carried out consistently in the Ketapang area.
“The activities that have been routinely carried out make children more aware. In fact, they take their own initiative to collect garbage, including those at the bottom of the river,” he explained.
Of the various types of waste that pollute the environment, plastic waste is the biggest challenge faced today. This is due to the high level of use of plastic in everyday life, including among children. In Ketapang Regency, for example, children still have the habit of buying snacks that are generally packaged in disposable plastic.
Nevertheless, children's awareness of the importance of maintaining environmental cleanliness is quite good. Although they still consume plastic packaged products, they have become accustomed to throwing garbage in place, not carelessly.
As part of its ongoing efforts, YIARI continues to educate children and communities in Ketapang, especially regarding the dangers and management of plastic waste. One of the positive habits that began to be built is to bring your own container or place to drink when buying snacks, in order to reduce dependence on disposable plastic packaging.
The garbage problem will never really end. However, as individuals, we can contribute through consistent small steps, such as sorting garbage, bringing our own containers, or regularly participating in environmental clean-up activities. Not having to wait for a certain moment such as the National Waste Care Day (HPSN), the action of maintaining cleanliness can be done every week, even every day, in the environment where we live.
As the children in Ketapang have shown-playing while picking up trash-this simple action has a big impact if done collectively. It's time we make caring about waste a part of our lifestyle. Yuk, from now on get used to picking up trash and throwing it where it should be!

In an effort to prevent the spread of zoonoses, the Indonesian rehabilitation initiation Foundation (YIARI) helda refresher trainingthemed zoonosis and one Health approach in Ketapang, West Kalimantan, on Tuesday, February 25, 2025.
The event took place over a full day at the Sir Michael Uren Learning Centre and was followed offline and online via the Zoom Meeting platform, enabling participation from various regions.
This training involved various stakeholders in Ketapang, including the Ketapang district Health Office, Puskesmas, Puskeswan, Dr. Agoesdjam, Regional Health Laboratory, and Department of Agriculture, Animal Husbandry, and plantation.
What kind of activities? Come on, listen!
Zoonoses are diseases or infections that can be transmitted between animals and humans, either directly or through intermediaries (vectors) such as mosquitoes or ticks. Some examples of zoonotic diseases include bird flu, rabies, Anthrax, dengue hemorrhagic fever (DHF), malaria, monkey pox, and Nipah virus.
According to data from the Plantation and Animal Husbandry Office of West Kalimantan province, about 75 percent of new diseases in humans in the past two decades have come from the transmission of animal pathogens. Of the 1,415 types of pathogenic microorganisms that affect humans, 61.6 percent of them are known to come from animals.
In Indonesia itself, several zoonotic diseases have been identified and become a major concern, such as rabies, Anthrax, avian influenza, and helminthiasis.
The high biodiversity in Indonesia, coupled with the rapid growth of the human population, magnifies the potential for interactions between humans and animals that can trigger the spread of this disease.
In a refresher training held on Tuesday, February 25, 2025, the Indonesian rehabilitation initiation Foundation (YIARI) invited various stakeholders in Ketapang, West Kalimantan, to jointly prevent the spread of zoonoses through the one Health approach.
The concept of One Health or One Health is a cross-sector integration that combines aspects of human, animal and environmental health holistically.
The participants targeted by this training include field health workers, health care providers, educators, to policy makers. The One Health approach is now considered the most effective strategy in dealing with the complex challenges of zoonotic diseases, which cannot be solved by one sector alone.
Through this collaborative approach, different sectors are encouraged to work together, share knowledge and make optimal use of resources.
Synergies between sectors are expected to strengthen the capacity of early detection, rapid response, and Prevention of zoonoses in a comprehensive and sustainable manner.
Through the training, YIARI hopes that the participants can understand more deeply the concept of One Health and recognize the types of zoonoses that are common in domestic animals, livestock, and Wildlife.
This training is also a forum for stakeholders to get to know each other, build networks, and strengthen commitments in preventing the spread of zoonotic diseases in their respective work areas.
Especially for field officers, this training is designed so that they are able to carry out early identification, recording, and reporting of zoonotic incidents appropriately.
With these skills, they are expected to be at the forefront of zoonosis prevention and control efforts at the community level.
The success of the One Health approach relies heavily on effective communication and solid coordination between sectors. Therefore, the training also emphasizes the importance of building harmonious and collaborative working relationships between the institutions and institutions involved.
In addition to strengthening technical capacity, YIARI also provided participants with an in-depth understanding of the impact of zoonoses on biodiversity and public health. Information based on field data was also submitted, including community activities in high-risk areas in Ketapang, which are considered vulnerable to the spread of zoonoses.
The refreshment training held by YIARI related to zoonosis and the one Health approach received a positive response from the stakeholders present. Throughout the activity, participants actively discussed and exchanged insights with the speakers interactively, discussing challenges and solutions in the prevention and treatment of zoonoses in the field.
To support the comfort of participants, the committee provides two coffee break sessions and one lunch. In addition, YIARI also facilitates shuttle services using buses or vehicles from the Health Office to the location of the activity, namely the Sir Michael Uren Learning Center.
This activity is a concrete proof of YIARI's commitment to zoonosis issues that are increasingly relevant in Indonesia. Given the close relationship between Zoonoses and pets, livestock and Wildlife, The One Health approach is considered a strategic solution because it involves collaboration across sectors—from health, environment and agriculture.
This commitment is also in line with the steps of the government which has issued the regulation of the Coordinating Minister for Human Development and culture of the Republic of Indonesia number 7 of 2022 concerning new guidelines for the Prevention and control of zoonoses and Infectious Diseases.
This regulation was issued in response to the increasing incidence of zoonotic diseases and new infectious diseases that have the potential to have a major impact, both socially, economically, security, and public welfare.
With the increasing awareness and synergy of various parties, there is no reason to be passive in the midst of a growing zoonotic threat. A collaborative and sustainable approach is key to taking care of human, animal and environmental health in an integrated way.
In agriculture, fertilizer plays an important role as the main support for plant growth and development. Without an adequate supply of nutrients from fertilizers, plants become vulnerable to pest and disease attacks.
This condition certainly has a direct impact on the quality of crops, both in terms of quantity and quality of fruit or vegetables produced.
In general, there are two types of fertilizers commonly used to fertilize plants, namely chemical fertilizers and organic fertilizers.
Among the two, organic fertilizers are increasingly recommended because they are more environmentally friendly and do not pollute the soil or water sources. One form of organic fertilizer that began to be widely used is liquid organic fertilizer (POC).
What is liquid organic fertilizer? Let's see a more detailed explanation of the following liquid organic fertilizer!
Liquid organic fertilizer (POC) is a liquid fertilizer made from natural ingredients through the process of fermentation or decay. Based on information from the scientific journal of Service and innovation, POC raw materials include organic waste such as plant residues, animal waste, and human waste containing various important nutrients.
POC contains two types of nutrients, namely:
In addition, POC also contains bioactive substances such as vitamins and enzymes produced by the activity of microorganisms during fermentation. These compounds support plant metabolism and increase resistance to environmental stress.
POC is more effectively applied directly to the leaves, stems, and flowers of plants. This is because plant tissues, in particular stomata (pores on the surface of leaves and stems), are able to absorb nutrients in liquid form quickly and efficiently.
POC is very beneficial especially in the initial growth phase of the plant and during the transition from the vegetative to the generative phase, in which the plant begins to flower or bear fruit. In addition to being a source of nutrients, POC also acts as a natural growth stimulant that helps accelerate the development of buds and flowers.
Liquid organic fertilizer (POC) has a number of properties that resemble solid organic fertilizers, despite their different physical forms. POC is liquid because it has gone through the process of fermentation or decomposition of organic matter naturally. The main characteristics of liquid organic fertilizers are:
As the name suggests, liquid organic fertilizer has a physical form in the form of a liquid. This form facilitates the process of absorption of nutrients by plants through leaves and roots.
Liquid organic fertilizer (POC) has a number of properties that resemble solid organic fertilizers, despite their different physical forms. POC is liquid because it has gone through the process of fermentation or decomposition of organic matter naturally. The main characteristics of liquid organic fertilizers are:
As the name suggests, liquid organic fertilizer has a physical form in the form of a liquid. This form facilitates the process of absorption of nutrients by plants through leaves and roots.
POC contains various important nutrients needed by plants, both macro nutrients such as nitrogen (N), phosphorus (P), and potassium (K), as well as micro nutrients such as iron (Fe), manganese (Mn), and zinc (Zn).
This complete nutrient content helps support optimal plant growth at all phases of life.
One of the main advantages of POC is its ease of application. This fertilizer can be sprayed directly onto plant parts such as leaves, stems, and flowers, or sprayed onto growing media such as soil or compost.
Thanks to the liquid form, POC is absorbed by plants faster than solid fertilizers. Nutrients can enter directly through the stomata on the leaves or through the roots, so that their effect on plant growth is felt faster.
POC can be made from various household and agricultural organic waste, such as vegetable scraps, fruit peels, animal waste, to kitchen waste. This makes POC a cost-effective fertilizer option while supporting sustainable organic waste management.
Because it comes from natural organic ingredients, liquid organic fertilizers are able to improve soil structure, increase organic matter content, and strengthen water binding in the soil.
This makes the soil looser and more fertile, thus supporting optimal plant root growth.
A well-fermented POC does not emit a fetid odor. On the contrary, this fertilizer has a characteristic and unobtrusive aroma of fermentation, so it is more convenient to use it, especially in domestic or urban environments.
In addition to serving as a source of nutrients, POC also contains live microorganisms such as bacteria and fungi. These microbes play a role in breaking down organic matter in the soil and suppressing the growth of pathogens that cause plant diseases naturally.
Quality POCs generally have a neutral to slightly acidic pH (around pH 6-7), which is ideal for most types of plants. In terms of appearance, this fertilizer is Brown to blackish brown, indicating an optimal fermentation process and nutrient-rich raw materials.
The regular use of POC has been proven to improve the quality of agricultural products. Plants produce fresher fruits and vegetables, more natural flavors, and better shelf life because they are obtained from balanced and natural nutrients.
In terms of use, liquid organic fertilizer (POC) offers higher convenience than solid organic fertilizer. The application is simply sprayed or watered, without the need for complex tillage processes.
However, POC is not ideal for being the main fertilizer in the long term, due to its nutritional properties, which are more easily washed out by rainwater or soil erosion.
Referring to the Journal of scientific and technological services (Polytechnic of Industrial Chemical Technology Medan), the following advantages and disadvantages of POC:
Low viability of microorganisms: microorganisms contained in POC have low viability, especially if storage is not carried out correctly.
Limited microorganism population: the number of microbes in the POC is often below 10 ° cfu/ml, which is low enough to significantly improve the soil in a short time.
Relatively low nutrient content: the main nutrients in POC generally come from added ingredients such as urea or NPK, rather than purely from organic fermentation.
Non-durable: POC has a short shelf life, usually less than one year, and is not suitable for long-term storage without special treatment.
Potential for contamination and odor: if not fermented optimally, POC is at risk of producing gases and pungent odors, and is susceptible to being contaminated with pathogens.
Not yet ideal for industrial scale: POC production is often still manual and not immediately ready for mass scale use without standardization.
Liquid organic fertilizer (POC) can be made independently by utilizing organic materials that are easily found around the environment.
The manufacturing process involves fermentation using effective microorganisms such as EM4, which contains Lactobacillus bacteria, Actinomycetes, Streptomyces, yeast, and photosynthetic bacteria. These microorganisms play an important role in accelerating the decomposition of organic matter into nutrients that are ready to be absorbed by plants.
Here's an example of a simple recipe for making POC:
The process of creating a POC cannot be done instantly. It takes at least two weeks of fermentation to produce fertilizer with good quality. The results of this POC can be used directly on plants, either sprayed on the leaves or sprinkled on the ground.
Liquid organic fertilizer is an environmentally friendly and economical solution to increase agricultural productivity. Both for household scale and wider agricultural land, POC offers ease of manufacture and use.
By taking advantage of the available organic waste, anyone can make their own fertilizer at home. Now, there is no reason to let plants grow without nutrients—even if only in the yard.
