Ultisol is a type of soil that is widely distributed and has the potential to be developed as agricultural land. However, this soil has major constraints in the form of low C-organic content and li…
The angsana plant is one of the plants that can successfully grow on critical land such as post-mining land. Microenvironmental factors such as soil moisture, soil temperature, light, and soil pH h…
Water balance provides an overview of the condition of water deficit or surplus. Water balance is closely related to climatic conditions, so climate greatly affects the water balance. In knowing th…
Ultisol is known as a soil type with low organic matter and nutrient content, high acidity, and low fertility. This type of soil is usually deficient in essential nutrients such as N, P, K, Ca, and…
Site-specific fertilization is very important for rice plant growth. Nitrogen (N), Phosphorus (P), Potassium (K) which are essential macronutrients that are needed precisely by rice plants in order…
Ultisol is a soil that has soil characteristic constraints that can inhibit plant growth and low P nutrient content, and low organic matter content. This study aims to analyze the effect of liquid …
Ultisol soils have low nutrient content, especially organic matter. One of the efforts to increase its fertility is the use of organic fertilizer from bamboo roots. Rhizobacteria in the root zone c…
Peat ecosystems are characterized by the accumulation of organic material that is partially decomposed due to anaerobic conditions. The decomposition of organic matter in peat soils is influenced b…
Peat has a high carbon content due to the large amount of organic matter that has accumulated over a long period of time. Carbon levels can be measured by calculating biomass and carbon above the s…
Oil palm (Elaeis guineensis Jacq.) is an annual crop that has the potential to absorb carbon emissions. In oil palm plantations, it is common to find weeds of various species that grow under stands…
Peatlands are ecosystems that have environmental functions, economic value, and ecological value. Peatlands are soils that form naturally from the weathering of vegetation that has grown on them ov…
Peatland is land that has a layer of soil that is not perfectly decomposed which is rich in organic matter (C-organic > 18%) with a thickness of 50 cm or more. The organic matter that makes up peat…
Soil fertility is the ability of the soil to provide essential nutrients in available form and in an appropriate balance. Mining often causes environmental damage, including decreasing soil quality…
Ultisol soils are nutrient poor, especially nitrogen. Urea fertilization is often less efficient, so organic fertilizers such as humic acid and biochar are needed to improve soil fertility. This st…
Ultisol is a type of soil formed in the tropics with low pH and relatively low nutrient content. This study aims to determine the effect of the combination of humic acid-biochar and urea fertilizer…
Soil is one of the important natural resources in the sustainability of plant life and environmental sustainability. The decline in the level of soil capability is indicated by soil erosion which c…
Soil fertility is the ability of soil to support plant growth by providing balanced nutrients. Low soil fertility makes constraints that can limit plant growth. This study aims to determine the sta…
Tidal swamp land in Central Kalimantan province has great potential for agricultural development, especially as a national food barn. The use of this land is faced with challenges such as low soil …
Global warming occurs due to the increase in carbon dioxide by human activities, as well as massive deforestation. The way to overcome this problem is by reforesting the forest so that carbon reser…
Tidal swamp is land that has the potential to be managed as agricultural land. Mulya Sari Village is a village located in a tidal area. plant groups, especially cassava commodities, are still littl…
Kolam pengendapan lumpur (KPL) berfungsi menampung dan mengendapkan partikel air limpasan yang berasal dari lokasi penambangan sebelum air tersebut dibuang menuju tempat pembuangan, dan sebagai tem…
Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian pupuk organik cair terhadap produksi padi (Oryza sativa L) pada tanah lebak serta mengetahui dosis terbaik untuk tanaman padi. Penel…
Erosion is the event of moving or transporting soil and soil particles from one place to another by natural media. The occurrence of erosion causes various kinds of losses such as erosion of the so…
Rivers are water flows formed through the process of flowing water either from rainwater, springs or water from glaciers into open streams. Rivers have many benefits in supporting human life and or…
Tanah rawa lebak merupakan tanah yang memiliki tingkat kesuburan tanah yang rendah dan kemasaman tanah yang tinggi. N-total yang rendah dan pH tanah yang masam menjadi hambatan bagi petani dalam pr…
Penilaian kesesuaian lahan merupakan proses yang melibatkan survei dan interpretasi topografi, tanah, vegetasi, iklim, serta aspek lain dari lanskap dengan tujuan khusus untuk mengidentifikasi pote…
Sedimen Kolam Pengendapan Lumpur merupakan bahan hasil sedimentasi pada kolam pengendapan lumpur yang terbawa oleh air limpasan yang disebabkan oleh aktivitas penambangan dan erosi. FABA (Fly Ash B…
Kolam pengendapan lumpur (KPL) yang terdapat pada area tambang batubara menimbulkan permasalahan dengan adanya sedimentasi lumpur hasil perawatan kolam pengendapan lumpur. Fly ash bottom ash merupa…
Soil fertility is the relationship of soil properties (physical, chemical and biological properties) that plants use to grow and develop a plant. Efforts that need to be made to increase soil produ…
Increasing the productivity of tea plants in Indonesia requires technological innovation in cultivation. One effort that can be made is intensification in the existing area with the application of …
