Development of an organic waste processing design based on fermentation technology for compost production at the faculty of teacher training and education Khairun university environmental areas

Abstract

Waste is a crucial problem that requires special handling. This research aims to make a tool for processing organic waste into compost and liquid fertilizer and then to determine the quality (content) of liquid fertilizer. The tool consists of 7 main parts, namely the frame, cover and waste input container, crusher, rotator, filter container, liquid storage container, and water faucet. The driving source for this tool is human power and the EM4 activator. The tool design measures 30 cm x 35 cm x 127 cm. This research method consists of 2 stages, namely: stage. · Design of equipment for processing organic waste into compost and liquid fertilizer; stage · Product testing and validation. The results of the research show that a waste fermentation tool for compost has been successfully designed. Based on the analysis of respondent data from the validator, it was concluded that the Organic Waste Processing Design Tool based on Fermentation Technology for Compost Production can be used with suggestions for improvement, with a feasible option for use with improvements as many as 4 respondents with presentation of 80% in the good or adequate category.
