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 aims to explore the relationship between soil hydraulic conductivity and irrigation management in drylands. Soil hydraulic conductivity, which measures the ability of soil to conduct water, was measured at several locations with varying soil types. The results showed that sandy soils have a higher hydraulic conductivity (average 1.2 cm/hour) compared to clay soils (0.15 cm/hour). Additionally, a survey of 100 farmers revealed that more efficient irrigation practices were applied by those who understood their soil characteristics. Regression analysis indicated that 67% of the variation in irrigation management efficiency could be explained by soil hydraulic conductivity. These findings emphasize the importance of understanding hydraulic conductivity in improving irrigation management practices and agricultural productivity in drylands.

Abstract

Climate change significantly impacts biodiversity in tropical regions, known as areas with the highest biodiversity levels globally. Rising global temperatures, shifting rainfall patterns, and extreme weather events disrupt ecosystem stability, causing habitat degradation, population declines, and even extinction of endemic species. This study aims to examine the effects of climate change on tropical ecosystems and explore applicable mitigation and adaptation strategies. The analysis reveals that species in tropical regions are highly vulnerable to environmental changes due to their dependence on stable climatic conditions. Ecosystem-based conservation, habitat restoration, and reducing greenhouse gas emissions are essential steps to ensure the sustainability of tropical biodiversity. Collaborative efforts among governments, scientists, and communities are necessary to minimize the impacts of climate change on tropical biodiversity.

Abstract

This study aims to explore the relationship between soil hydraulic conductivity and irrigation management in dryland areas. Soil hydraulic conductivity, which is a measure of the soil’s ability to transmit water, was measured at several locations with varying soil types. The results showed that sandy soils have higher hydraulic conductivity (an average of 1.2 cm/hour) compared to clay soils (0.15 cm/hour). In addition, a survey of 100 farmers indicated that more efficient irrigation practices were applied by those who understood their soil characteristics. Regression analysis showed that 67% of the variation in irrigation management efficiency can be explained by soil hydraulic conductivity. These findings highlight the importance of understanding hydraulic conductivity to improve irrigation management practices and agricultural productivity in dryland areas.
