| Abstract | This research aimed to develop a liquid organic fertilizer from climbing perch (Anabas testudineus) processing waste to increase the value of agricultural by-products and mitigate environmental pollution. The experiment utilized fish heads and entrails as the primary raw materials, mixed with cricket frass, molasses, and rice bran in various proportions. The experimental design consisted of 9 treatments with 3 replications each. Fermentation was conducted in 200-liter tanks with a working volume of 160 liters for 14 days under continuous aeration. Chemical analysis of the resulting liquid organic fertilizers revealed a pH range of 6.00 to 6.49, nitrogen (N) content of 1.54-2.21%, phosphorus (P) content of 0.40-0.86%, and potassium (K) content of 0.76-1.17%. Efficacy testing on Green Oak lettuce demonstrated that Formula 7 (comprising 70% climbing perch waste, 15% cricket frass, and 15% molasses) yielded the highest growth performance and fresh weight. These results were highly significant (p < 0.01) when compared to other organic fertilizer treatments and were comparable to the growth of Green Oak lettuce treated with a 21-3-3 liquid chemical fertilizer. The findings indicate that climbing perch processing waste can be effectively converted into a high-quality liquid organic fertilizer, which not only helps reduce environmental problems but also holds potential for future commercialization as a community product. |
