Treatment of garden waste by using Indigenous Microorganisms (IMO)

Abstract

Composting refers to the processing of organic wastes are biologically caused by the action of bacteria and microorganisms. The end product of the compost produced is known as the expected potential which acts as a fertilizer plant and a good soil additive. The review of Treatment of Garden Waste by using Indigenous Microorganisms (IMO) is an effort to produce quality organic fertilizer to reduce reliance on chemical fertilizers in crop production. The characteristics of the microorganism found in organic fertilizers help to fertilize the soil and to treat the soil structure. Preparation of IMO 1 to IMO 5 by using materials such as Rice Husk Ash (RHA), and Goat Dung (GD) is a preliminary method in the study. Composting process using IMO 5 with garden waste and chicken manure in the ratio of 2:2:1 as compost. Characteristics of the identified bacteria found in indigenous microorganism (IMO) of the IMO 1 to IMO 5 is a bacterium Bacillus kind of categorized as Gram-positive bacteria that produce rod-shaped cells that are colored purple-black. Compost product has a pH between pH 5.5 to pH 8.5. Compost decomposition assisted by microorganisms. On average, the microorganism was using 30 parts C and N in one part of the final compost. Therefore, the C/N ratios in the range of 30:1 in compost media provide the perfect balance of nutrients to the efficiency of the activity of microorganisms. The moisture content of the final compost material Rice Husk Ash (RHA) is 42.8 %, while that of Rice Bran (RB) is 36.2 %. The temperature of the compost end of RHA and RB is about 28°C and 30°C at which temperature the maturity is static until the end of the composting process. Continuously use of compost fertilizer can be maintained its chemical properties, physical and biological soil as well as the supply of plant nutrients.
