Sustainability Design on Use of Biomass Waste Gasification Technology for Small Industry of Palm Sugar in Sinarlaut Village

Sinarlaut Village is located in Agrabinta District, Cianjur Regency, West Java Province. The community is mainly farmers, and some people produce palm sugar from coconut tree sap. Farming activities produce various agricultural waste. One of them is an abundant rice husk. This research conducted an analysis focusing on the feasibility of implementing gasification technology in supporting small industry palm sugar. The study was conducted not only on the technical aspect but also on the multi-variable sustainability aspect. One business cooks around 60 liters of sap for 6-8 hours to produce approximately 20 kg of palm sugar daily. The community uses firewood to cook coconut tree sap. They need around 50 kg/day firewood equivalent to 197,400 kcal/day. Based on the calculations, 59,818 kg of rice husk is an alternative resource to replace wood as fuel for cooking sap by gasification technology. The evaluation shows disadvantages and gap problems in terms of social, operation and maintenance, readiness to use, waste, land availability, and safety standard that should be managed. To implement the technology diffusion, social engineering needs to be conducted in the community to build system sustainability. The challenge will be more substantial for the effort to implement gasification technology on mass scale.
