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

This study examines the effect of varying light intensity on photosynthesis efficiency in plant growth. Photosynthesis is a vital process for plants, relying on solar energy to convert carbon dioxide and water into glucose and oxygen. The intensity of light received by plants significantly determines the efficiency of photosynthesis and plant growth. This research was conducted using a literature review method, analyzing various scientific sources to understand how light intensity affects the photosynthesis process. The results indicate that optimal light intensity enhances the rate of photosynthesis, while excessively low or high intensity can hinder plant growth. Other factors, such as light spectrum, light duration, and plant adaptation to specific light conditions, also influence photosynthesis efficiency.

Abstract

Crop rotation is one of the cultivation strategies that can improve agricultural productivity, especially in dryland areas characterized by limited water and nutrient availability. This study aims to analyze the effectiveness of various crop rotation types on maize (Zea mays L.) production in dryland conditions. The research was conducted using a field experiment with a randomized block design (RBD) consisting of four treatments: maize after soybean, peanut, sweet potato, and continuous maize cropping (monoculture) as a control. The results showed that rotation with leguminous crops, particularly soybean, significantly increased maize yield compared to monoculture. In addition, crop rotation improved agronomic parameters such as plant height, number of leaves, and leaf greenness index. Soil conditions also improved, as indicated by looser soil texture and higher organic matter content. Thus, crop rotation is proven to be an effective and sustainable approach to increasing maize productivity in dryland farming systems.
