Waste from traditional market places is the second source of municipal solid waste in Indonesia. At current condition of the absence of source separation, the traditional market waste may be more attracted to be managed in a business scale compared to household waste. The attributed reason is that the waste has characteristic of more uniform waste, more concentrated source, higher organic fraction and less hazardous waste. The aim of this study is to compare different options of organic fraction MSW disposal systems by means of Life cycle assessment (LCA) and economic assessment. The options compared are aerobic digestion in labour intensive, aerobic digestion that utilise simple capital of wheel loader, anaerobic digestion and landfill for electricity generation. The current open dumping scenario was also included as the baseline of comparisons. The relevant impact categories assessed in LCA are the green house effect and the acidification potential.  Result shows that all options proposed could reduce the environmental impact of current dumping. Anaerobic digestion performs the lowest impact of greenhouse effect. Anaerobic digestion may perform the highest impact of acidification potential among options proposed, though the environmental impact of biogas electricity production from this scenario is lower than the environmental impact of existing grid electricity production. Landfill for electricity generation performs the highest impact of greenhouse effect among options proposed. Economic analysis shows that only aerobic digestion scenario is economically feasible.

Key words : municipal solid waste, organic fraction municipal solid waste, life cycle assessment, economic analysis
