Production of Local Microorganism by Utilizing Organic Matter in PT Ultra Peternakan Bandung Selatan

Abstract

Unmanaged waste in livestock can cause pollution, but it can benefit the environment if managed properly. PT Ultra Peternakan Bandung Selatan reported that effluent produced every day from this farm is about 150.000 liter. The application of local microorganisms (MOL) could be practical because used as a starter for decomposition. However, the most efficient way to produce MOL to manage waste effectively in this company needs to be carried out. This study aimed at improving effluent management by using MOL most efficiently from some organic matters. The analysis performed three treatments for making 10 liters MOL: M1 (Main MOL + molasses + water), M2 (Main MOL + mastitis milk), M3 (Main MOL + milk MOL + water). Each treatment was given a dose of 10% and 15% of 10 liters for main MOL, molasses, and milk MOL. The fermentation experiment was carried out by mixing all the ingredients, that is, main MOL, molasses, and water for M1. For the second ingredient, M2 is mixing mastitis milk and main MOL. Then M3 combines the main MOL, milk MOL, and water. After seven days fermented, observations in local microorganism characteristics were pH, density, and brightness value. The result suggested that treatment M2 (Main MOL + mastitis milk) 10% was the most efficient local microorganism reproduce based on the pH is 4,36, density has a value of 531 gram, and brightness value is 897 lux. The study underlined the importance of mastitis milk to produce MOL and seems effective and efficient to improve the effluent before being evacuated to the land.
