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.

Crop rotation is an environmentally friendly agricultural method that is effective in maintaining soil fertility and reducing pest attacks. This study aims to assess the impact of legume crop rotation, especially groundnut (Arachis hypogaea L.), on soil quality. The study was conducted through literature studies from various scientific sources. Results show that groundnut is able to improve soil through symbiosis with nitrogen-fixing bacteria such as Rhizobium sp. and encourage functional microbial activities such as nitrifying bacteria (Nitrosomonas sp. and Nitrobacter sp.). Crop rotation also increases organic matter content, improves soil structure, and increases the availability of nitrogen in the form of nitrate that is easily absorbed by plants. In addition, root exudates from groundnuts enrich the rhizosphere with beneficial microorganisms. Overall, legume crop rotation contributes greatly to improving soil fertility in a natural and sustainable manner.

The use of mulch is one of the effective soil and water conservation techniques to increase soil moisture and water use efficiency on agricultural land. Mulch functions to suppress the rate of water evaporation from the soil surface, maintain temperature stability, improve soil structure, and support microorganism activity. This literature review aims to understand the effect of mulch use on soil moisture and water conservation based on previous research results. The results of the review show that the provision of mulch, both organic and inorganic, can significantly increase soil moisture by reducing evaporation, increasing water infiltration, and maintaining soil temperature stability. However, excessive mulch thickness can interfere with soil aeration and root respiration processes, so it needs to be adjusted to land conditions and plant types. Therefore, the proper use of mulch can be an important strategy in sustainable soil and water management, especially on agricultural land in tropical and dry areas.
