ANALYSIS OF USERS' PERCEPTION ON BIOGAS, CHARCOAL BRIQUETTE AND DRY SOLID WASTE USAGE IN KUPANG MUNICIPALITY

Abstract

This perception survey shows that the perception onthe utilization of biogas, charcoal briquettes and dry
organic waste as fuel, tested by Geng Motor IMUT (GMI) is positive, in economic, social and ecological aspects.
The strongest positive perception is on economic and ecological aspects. While in social aspect, it is not
significant, where increased social interaction and the formation of networks and organizations are not proven in
this study. The main influencing factors are the perceived object and situation. Economic analysis of the three
technologies shows a positive and profitable feasibility. This can be seen from: 1) Positive NPV value with a
calculation of 15 years for biogas with DePo BiMuT S-002 and 10 years for charcoal briquettes and dry organic
waste with GMI F-003 biomass stove at 17% interest rates; 2) B/C Ratio with value above 1 (one); 3) Small
value for payback period, or investment costs are paid off the fastest in the first year for charcoal briquettes and
dry organic waste with the GMI F-003 biomass stove and the second year for biogas with DePo BiMuT S-002.
Key words: perception, utilization, biogas, charcoal briquettes, dry organic waste, portable digester, DePo
BiMuT S-002, Biomass stove GMI F-003.
