<p align="justify">Soybean is a legume with high nutritional value and the most popular vegetable protein source to Indonesians. One of the cause of the low production number of soybean is the decreasing availability of fertile soil. To overcome this problem, fertilization is done via the plant"s body (leaves). The utilization of biological fertilizer based on microorganism has been done, among others to use microalgae as the source of biological fertilizer. The purpose of this research is to determine the most optimum concentration of dried Spirulina sp. leaf fertilizer to increase the production of soybean production. <br /> <br /> <br /> The research was done in Screen House ITB Jatinangor with concentrations of dried Spirulina sp. at 1 g/L, 20 g/L, and 40 g/L. The research uses Complete Random Design. Statistical analysis using Analysis of Variance (ANOVA) shows that the utilization of leaf fertilizer Spirulina sp. did not have a significant effect to each of the measurement parameter. The average age of blooming at concentrations of 0, 20, and 40 g/L is 47.46, 46.21, and 45.92 HST respectively. The average age of harvest at concentrations of 0, 20, and 40 g/L is 17.33, 20.67, and 25.92 respectively. The average number of beans at concentrations of 0, 20, and 40 g/L is 34.83, 42, and 47.42 respectively. The average weight of beans at concentrations of 0, 20, and 40 g/L is 3, 4.2, and 4.65 g respectively. The average weight of 100 beans at concentrations of 0, 20, and 40 g/L is 8.64, 10.11, and 9.71 g respectively. The average water content of the beans at concentrations of 0, 20, and 40 g/L is 7.5%, 3.5%, and 13.25% respectively. Observation shows the best results for treatment with Spirulina sp. as a leaf fertilizer at 40 g/L.<p align="justify">
