Abstract
The campus is a place for people to gain knowledge in higher education, from human activities and the environment in the form of plants, it will produce waste in the form of organic and inorganic waste. Organic waste is waste from human activities which continues to increase and has an impact on environmental pollution, organic waste in the form of food waste, paper waste and leaf waste, etc. Organic waste management must aim to improve public health and environmental quality and make waste a resource with economic value. This research aims to determine the decomposition process of campus organic waste using Bioactivators so that the decomposition time is faster, to determine and improve the quality of compost from organic waste and to determine its effect on the growth of sweet corn and the fertility of Regosol soil. The research was carried out in 2 stages, namely Stage 1, Decomposition process of campus organic waste with a combination of livestock waste: Factor 2 types of bioactivators: a. Mixed culture (EM4), b. Pure culture (lignolytic), c. Trichoderma. Stage 2. Testing the quality of compost using the method used is a Completely Randomized Design with treatments: K0: Soil without compost- K1: Soil with quality 1 compost- K2: Soil with quality 2 compost- K3: Soil with quality 3 compost- K4: Soil with quality 4 compost- K5: Soil with quality 5 compost- K6:: Soil with ponska fertilizer (NPK). Observational data was analyzed using variance (Anova) at a confidence level of 95%. To test differences between treatments, Duncan^s multiple range test (DMRT) was used with a significance level of 5%.
The research results showed that compost and organic waste in a ratio of 50%:50% had the best corn plant height, for the best bioactivator by providing magot bioactivator, the highest N content analysis was obtained from straw waste.
