Abstract

This study aims to evaluate the effectiveness of using Lactobacillus sp. bacteria as an Effective Microorganism (EM) solution derived from kepok banana peel waste to treat tempeh wastewater. The research was conducted using four reactors with varying EM concentrations (0%, 10%, 20%, and 30%) that were processed over 16 days. The results demonstrated a significant decrease in COD, BOD, and TSS levels. Reactor R4, containing 30% EM, reduced BOD by 78.01%, increased DO to 1.31 mg/L, and raised pH to 5.86. Reactor R3, with 20% EM, achieved the highest COD reduction of 78.13%. Additionally, Reactor R2, containing 10% EM, reduced TSS by 66.81%. This study indicates that EM derived from kepok banana peel waste can effectively degrade organic pollutants in tempeh wastewater, offering an environmentally friendly treatment method.

Abstract

Organic fertilizer raw materials that can be obtained naturally and are rich in fertilizer nutrients can be found in animal slaughtering activities. Slaughtering activities generally produce animal waste and manure, which can be used as raw material for organic fertilizer. This study aimed to investigate the effect of the composition of raw materials on the quality of organic fertilizers. The organic fertilizer parameters studied were C/N, P, K, pH, and temperature. This study used four reactors with each reactor volume of 120 L and the exact weight of raw materials in each reactor of 20 kg. Variations in the composition of the raw material of the rumen of Madura cattle and straw in this study were RK (100% cow rumen), R1: (65% cow rumen: 35% straw), R2: (50% cow rumen: 50% straw), R3: (35% cow rumen: 65% straw). The composting process is carried out for 50 days. Analysis of the quality parameters of organic fertilizer using SNI 2803: 2010. The results showed that differences in the content of the raw materials impacted the quality of the generated organic fertilizer. R3 (35% rumen cattle: 65% straw) with C/N ratio = 13.25, P = 6.12%, K = 7.55%, pH = 6.82, and Temperature = 33.7oC are variations in the raw material composition for Madura cattle rumen and straw that fulfill the quality criteria of the Regulation of the Minister of Agriculture Number 70 of 2011.
