PROCESSED MAKING ORGANIC FERTILIZER FROM SLUDGE OF SNAKEHEAD FISH (CHANNA STRIATA BLOCK, 1793) POND FARMING COMBINED WITH ORGANIC MATERIALS

Abstract

This study was conducted to evaluate the effectiveness of reuseing sludge of snakehead fish pond farming in combination with organic materials as fertilizer. Waste sludge after each fish harvest is collected and dried for 7 days, then mixed with organic materials (peanut shell and coir fibre) at the ratio of 10% sludge: 90% organic material; 30% sludge: 70% organic material; 50% sludge: 50% organic material and 70% sludge: 30% organic material incubated for 90 days, the experiment was designed with 5 treatments and three replicates for each treatment. The analysis results showed that the highest nutrient content of manure expressed in treatment 4 was 30% sewage sludge combined with 70% organic material, the lowest was treatment 1 90% sludge +10% organic material.
