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

A legume crop with strategic importance in meeting national food needs, groundnuts (Arachis hypogaea L.) have the ability to be grown in arid regions. However, boosting this crop's output is hampered by low rainfall and soil fertility. This study uses a literature review technique to scientific journals for the 2021–2025 period in order to determine the impact of planting distance and organic fertilizer dosage on peanut development and yield in drylands. The analysis's findings demonstrate that ideal spacing, like 40 cm by 20 cm or 30 cm by 15 cm, can greatly boost peanut seed output and vegetative growth. Meanwhile, the application of organic fertilizers such as manure and biochar is proven to improve soil physical and chemical properties, increase water retention, and support nutrient absorption by plants. The synergy between proper spacing and organic fertilizer application can increase yields by more than 30%, and support sustainable cultivation systems on marginal land.
