Abstract

Leaf waste problem at TPST UNDIP has not been resolved optimally. The TPST UNDIP has utilized leaf waste to be used as compost using conventional composting method. However, leaf waste processing by conventional composting method takes a relatively long time and the quality of compost produced is not good. This research answer the challenge by applying one of organic waste processing alternative that is vermicomposting method. Vermicomposting is a method of composting organic waste aerobically by utilizing earthworm as a decomposer. The advantages of vermicomposting method is the process of decomposition of waste run faster and the quality of compost products increased. This research uses composting variation that is composting and vermicomposting during each 14 days. The resulting compost was then tested for its macro element content on days 2,4,6,8,10,12 and 14. The results of this study indicate that the vermicomposting method can decrease the C-Organic level and can increase the levels of N-Total, P-Total and K-Total are most optimal when compared to composting. In addition, vermicomposting is not effective for reducing leaf waste. Because Lumbricus rubellus worm is only able to consume leaf waste as much as 7.93% / day of body weight.
