Mung bean (Phaseolus radiatus L.) is an important agricultural commodity in Indonesia, widely cultivated due to its short harvest period, drought tolerance, and high nutritional value. However, the increasing demand for mung beans has not been matched by optimal production, necessitating innovations in cultivation techniques, particularly in water management. This study aims to examine the effect of different volumes of water media on the growth of mung beans. The research employed an experimental method using a Completely Randomized Design (CRD), involving nine mung bean seeds divided into three treatments with water volumes of 10 cc, 15 cc, and 20 cc, each replicated three times. Observations were conducted over seven days, focusing primarily on plant height. Analysis of variance (ANOVA) revealed significant differences (p < 0.05) among treatments. The 15 cc water volume resulted in the best growth, indicated by the highest average plant height at the end of the observation period, while 10 cc and 20 cc volumes produced less optimal growth. Insufficient water caused drought stress, whereas excessive water led to overly saturated media that impaired root respiration. This study underscores the importance of proper water volume regulation in mung bean cultivation to support optimal growth and prevent yield losses.

Photosynthesis is a vital process for plants in converting light energy into chemical energy stored in organic compounds. Light intensity is one of the main factors influencing the efficiency of this process. This study aims to determine the effect of different light intensities on the photosynthesis rate and growth of spinach plants (Amaranthus sp.), which is a C4 plant species.The method used was a quantitative experiment with three light intensity treatments: low (0–10 lux), medium (10–20 lux), and high (>20 lux), each replicated three times over six weeks. Observed parameters included plant height, number and length of leaves, as well as the photosynthesis rate measured using the IRGA method.The results showed that light intensity significantly affected the growth and photosynthesis rate of spinach plants. The high light treatment produced the most optimal growth, with an average plant height of 4.92 ± 0.4 cm and the highest photosynthetic activity. Conversely, the low light treatment caused symptoms of etiolation, reduced vitality, and faster plant death, averaging by the third week.In conclusion, increasing light intensity significantly enhances photosynthesis efficiency and growth in spinach plants. These results can serve as a basis for regulating light intensity in cultivation systems, both conventional and hydroponic.  

This study aims to determine how effective the fermentation process is carried out by the microorganism Saccharomyces cerevisiae in a soluble sugar medium, and how the sugar concentration affects the volume of carbon dioxide gas produced.
