Abstract: Effective Microorganism-4 (EM-4) is a highly effective bio-activator to inoculate organic waste to accelerate the decomposition process. Various researches related the use of EM-4 in deciphering organic materials has a lot to do, but only a few are doing research on the use of EM-4 dose right in outlining household organic waste. This study aims to determine the effect of EM-4 with respect to time and the quality of the composting as well as the utilization of biotechnology in high school teaching materials. The study consisted - of experimental and descriptive quantitative research. In the experimental stage, composting is done to look mature compost with design for six treatments and three repetitions. Composting speed is calculated based on the time of composting and compost quality parameters seen by nutrient content (C-organic, N-organic, the ratio of C/N, P2O5 and K2O), whereas quantitative descriptive research is used to determine whether the materials are made viable if used as teaching materials. The analysis showed there is a real gift influence bio-activator Effective Microorganism -4 (EM-4) on the speed and quality of results composting (p<0,05). Addition of Effective Microorganism-4 (EM-4) during composting can increase the abundance of microorganisms in the material and then of course the overhaul will accelerate the process of organic matter into compost. If the organic material can be completely overhauled, the more nutrients are released in the compost pile include elements N, P, and K organic.
Key Words: Effective Microorganism-4 (EM-4), speed composting, compost quality, teaching materials
