This research aimed to transfer technology of biogas construction for applying the biogas in household. The villagers were instructed and trained about digester construction for applying the biogas produced from cow and pig manure. The produced biogas was used as alternative fuel for cooking in household to replace LPG. The research operation was separated to 3 phases. the first was preparation and introduction. The second was instruction and practical training. The last was monitoring and project evaluation. The number of participants was 30. The number of biogas digester pilot household was 10. From the project evaluation by using the five-rating scale questionnaire it was found that the evaluation about cognition showed the maximun level (x=4.42 S.D. = 0.84). The second was about location duration and food (X = 4.36 S.D. = 0.75). The lowest was about knowledge application (X= 4.28 S.D. = 0.77). For the project evaluation of success it was found that every biogas digester can be used and the produced biogas can be used to replace LPG about 1.8-2 hrs/a day/a housenold. They can save the expenditure about 180-200 Baht/a month/a household. The biogas digester construction cost was about 3000 Baht/a household. So the payback period was 1.38 years.

Educational system designed to produce Biogas from food waste. By comparing the quality of pigeon dung. And the value of the pig was used as the catalyst. In anaerobic conditions. Purpose was to compare the quality. And the amount of gas from the two types of catalyst used and the process of building a compost bin for households in the city. Which places the living repository of materials Rajamangala University of Technology PhraNakhon. Bangkok campus as a place of experimentation. The fermentation process is used for the same condition is temperature materials and processes in each trial which takes a total of 60 days separated by a period of preparation. During the experiment. And at the conclusion of the experiment. The 10-day period of preparation for the trial and during the 40 days of the conclusion of the 10-day trial that the mixed infection. And rubbish food for 10 days to wait for an extended amount of infected nodes Jane Mehta. The index values are measured. System including temperature fermentation - acid alkaline VOCs. Hydrogen sulfide oxygen carbon monoxide and methane gas in the range 12.00 pm - 13.00 pm every day for 30 days The result was the conclusion that Swine manure fermentation properties of methane higher than the pigeons in 3: 1 can be seen from the measurement equipment and systems. The odor is caused by the pigeons is very low and almost no odor. When compared to the after-fermentation of swine manure to 19 days while the smell of fermentation of swine manure odor remains
