Technology transfer on construction and using biogas for household in ban tatongdang tak province

Abstract

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 3,000 Baht/a household. So, the payback period was 1.38 years.
