Anti-Smell and Compost Powder (ASC)

Abstract

Nowadays, the reuse of waste to make fertilizer has been less applied. The objectives of this study were to produce Anti-Smell and Compost powder (ASC) as well as compare the strength of the smell and compare the decomposition time. The main purpose of ASC powder was to eradicate the smells produced by waste and to help decrease the decomposition time for compost fertilizer. The composting process divided into three condition; waste mixed with ASC, waste mixed with Bokashi, and waste without any mixture. The researcher distributed a questionnaire to test the smell from 350 respondents in Kota Kinabalu Polytechnic (PKK) area comprising of the PKK residents. The results of the study showed that ASC powder successfully achieved the objective, which the ASC mixed waste produced less smell compared to the other two samples. 69% chose with waste ASC powder will reduce the smells. While, the composting time for waste with ASC powders is more rapidly decomposing compared to existing products where in the second week ASC interventions began to show signs of decomposition. In the other hand, the temperature of the ASC approximately to ground temperatures which is at 32°C and for the waste with ASC powder textures is medium and a bit hard after 3 weeks. In conclusion, the results show that ASC powder can reduce the smell rate and accelerate the decomposition process and make the waste as compost fertilizer.
