Oil palm (Elaeis guineensis Jacq.) is a plantation crop that plays a significant role in Indonesia's agricultural sector. Oil palm seedlings require the support of a good growing medium and fertilizer, including soil amendments such as compost. Vermicompost is one organic material that can be used to improve soil. NPKMg (15-15-6-4) fertilizer is a compound fertilizer containing complete macronu…
The background of the research is based on the problem of limited availability of quality forage, especially in the dry season and limited availability of quality forage, so that efficient, fast-harvesting, and environmentally friendly feed innovations are needed. This study analyzes the use of low-quality rice grain as raw material for Hydroponic Green Feed (PHH) with the addition of liquid or…
Bentonite is a layered material that can be modified to improve its physicochemical properties through a pillarization process. This study aims to synthesize Co–Mo bimetals dispersed on Al13-pillared bentonite (BPILC) and analyze the effect of Co-Mo variations on its physicochemical characteristics. The synthesis was carried out through pillarization using Al13 polycation followed by wet impr…
Polyculture is a cultivation technique used to maximize yields. Maize was chosen because of its high carbohydrate content, and chilies because of their high vitamin A and C content. However, there was a decline in production due to abiotic factors related to living organisms and biotic nutrient elements. C. odorata mixed with eggshells is thought to have properties that can be utilized as ferti…
Red chili plants (Capsicum annuum L.) are one of the horticultural commodities that are widely cultivated in Indonesia and are favored by the public and have a fairly high economic value. One of the efforts that can be made to get an increase in red chili production can be done in various ways, including improving cultivation techniques which include superior varieties, spacing and fertilizing.…
