This research was studied and transferred the biogas production technology with the community participation using anaerobic dry fermentation system from agricultural residues. The production of renewable energy for replacing LPG in household cooking of Koh Khan Sub-district community Cha-Uat District Nakhon Si Thammarat Province was carried out. The efficiency of the biogas production from different co-digestion material with fresh cow manure was studied for 45 days. The experiment 1 bananas and papaya and the experiment 2 rice straw and coconut meal were used for fermented materials. It was found that the system using rice straw and coconut meal as a fermented material had a higher potential than using bananas and papaya. The system produced averaged biogas of 150 L/d and an average methane content of 67.68% respectively within just 15 days after start-up. While bananas and papaya as fermented materials took more time with more than 30 days after start-up the system. The system produced averaged biogas of 120 L/d and an average methane content of 64.64%. For usability test It was found that 150 L of biogas could continuously cook for 45-60 minutes. The 85% of the technology transfer recipients regarded that the knowledge gained as practical and reduced household expenditures. Additionally the system can produce biogas for a long time without adding new fermented materials. Therefore this biogas system could be applied to local agricultural waste for biogas production which can be expanded to other areas.

Young coconut shells are a byproduct after processing coconut juice which can be used to produce a solid-fuel. This fuel from the coconut shell is an alternative source instead of using firewood or charcoal made of timber in the natural forest. The solid-fuel from young coconut shells was prepared by using a wet glue powder as a binder then was compressed by using a briquette machine. The black coconut briquette was stable after exposure to the sun. The average of the briquette combustion rate was at 11.24 g /min. There is no eruption smut smoke and odor by using the young coconut shell briquette yo start a fire. To sum up a young coconut shell has a high potential as an alternative biomass material for producing a briquette especially for commercial. This solution can increase the reduction of haze weather in the sight of solid waste incineration and also global warming.
