Abstract

This study was conducted to explore the differences in the rate of photosynthesis in plants growing in light and dark environments, focusing on corn (Zea mays) and mung bean (Vigna radiata). Photosynthesis is an essential process that allows plants to generate energy from sunlight, with light being a key factor that determines the efficiency of this process. In this study, the plants were grown in two different conditions: a light environment with direct sunlight exposure and a dark environment with no light exposure. Observations were made over a period of one month to record the morphological and physiological differences in the plants. The results showed that plants growing in the light environment had a higher rate of photosynthesis, indicated by fresh green leaves due to optimal chlorophyll formation.

Abstract

This study examines the influence of soil thermal properties on the growth of horticultural crops in various climate zones, namely tropical, subtropical, and temperate. Soil thermal properties parameters measured include thermal conductivity, heat capacity, and thermal diffusivity. The results showed that soils in tropical climate zones, with higher conductivity and heat capacity, support more optimal growth of horticultural crops compared to subtropical and temperate climate zones. Regression analysis showed a positive relationship between soil temperature and plant growth, where optimal soil temperature conditions enhance plant physiological activities such as germination and nutrient uptake. These results emphasize the importance of adaptive soil management strategies based on soil thermal characteristics to increase horticultural crop productivity in the face of varying climatic conditions

Abstract

Efficient use of fertilizers is crucial for increasing agricultural yields while maintaining environmental sustainability. This research aims to optimize fertilizer usage through a mathematical model that can describe the relationship between the amount of fertilizer used and the agricultural output achieved. The model employs optimization theory to determine the most effective fertilizer dosage based on various factors such as crop type, soil conditions, and climate. With this approach, it is expected that fertilizer use can be carried out efficiently, reducing waste and minimizing negative environmental impacts. The results of this model can provide recommendations for optimal fertilizer dosages for farmers to improve productivity while considering costs and minimal ecological impact
