The research objective was to determine the results of utilization of fish and egg shell waste as liquid fertilizer in an effort to reduce environmental pollution and increase soybean yield. This study was conducted in the field using the Randomized Block Design (RBD) method. Liquid Fertilizer Treatment (P) tried: P0 = without liquid fertilizer (control), P1 = liquid fertilizer from fish waste, P2 = liquid fertilizer from eggshell waste, and P3 = liquid fertilizer from fish waste + eggshell. Each treatment was repeated 3 times, Planting was carried out on 12 trial plots (4 treatments x 3 replications), plot size of 4 m x 6 m. The data obtained were analyzed using Analysis of Variants(ANOVA), and if there are significant differences between treatments, followed by the 5% Smallest Significant Difference (LSD) test. The results showed the application of liquid fertilizers made from fish and egg shell waste, had a significant effect on increasing plant growth (number and height of soybean plants), reducing the number of empty pots, increasing the number of filled pots,thus increasing the yield of dried seeds/ha. The results showed the application of liquid fertilizer made from fish and egg shell waste, influencing liquid fertilizer made from fish waste and eggshells which were tried to be able to produce soybeans ranging from 3.43 to 3.7 tons/ha of dry beans higher and significantly different than controls that only able to produce 1.95 tons/ha of dried seeds. The results showed that the application of liquid fertilizers made from fish and egg shell waste, had an effect on the use of organic fertilizers made from fish waste and egg shells which were tried to significantly improve the yield of dried soybean seeds 22.5% - 32.1% compared to plant descriptions. In the long term, the provision of liquid fertilizer made from fish and egg shell waste, besides being able to increase soybean yield, is expected to increase land productivity;reduce environmental pollution and prevent land degradation.
