Abstract

This study aims to develop nitrogen extraction from natural growth regulators to support efficient and environmentally friendly organic farming. Experimental methods were used with biological materials such as bamboo shoots, bean sprouts, leaves, brown sugar, EM4, and coconut water. The procedure involved fermentation for seven days to produce liquid ZPT. The results showed that nitrogen extraction from these natural materials effectively increased the growth potential of plants. The color, texture, and composition of the solution changed during the fermentation process, reflecting the activity of microorganisms supporting the development of the ZPT. The discussion highlighted the potential of utilizing natural ZPT as an alternative to synthetic fertilizers that are expensive and have a negative impact on the environment. This research concludes that nitrogen extraction from biological materials is an innovative solution for sustainable agriculture with cost efficiency and minimal environmental impact. Large-scale implementation could extend its benefits to farming communities, particularly in agrarian regions such as Nias Islands.

Abstract

The productivity of peanut (Arachis hypogaea L.) is greatly influenced by the quality of the soil in which it is cultivated. Poor soil structure and low organic matter content are among the main limiting factors for optimal peanut growth. One potential solution is the use of rice husk charcoal (biochar) as a soil amendment. Rice husk charcoal has been shown to improve the physical and chemical properties of soil, such as enhancing porosity, cation exchange capacity (CEC), and soil pH. This study is based on a literature review of various scientific sources discussing the application of rice husk charcoal in crop cultivation, particularly legumes such as peanuts. The review indicates that rice husk charcoal can increase nutrient availability, improve soil aeration and water retention, and support root development and pod formation. Several studies also report yield increases of up to 20–30% in peanuts when appropriate doses of rice husk charcoal are applied. Therefore, rice husk charcoal can be recommended as an environmentally friendly soil amendment for sustainable peanut farming systems.
