This research aims to transfer biogas digester construction technology and application of biogas in household to teachers and students of Suksasongkhro Tak school. They were instructed and trained about biogas digester construction and application of biogas produced from animal manure on household cooking in order to reduce LPG use. A total number of 330 teachers and students participated in the training. Results from 5-point scale questionnaire for project evaluation showed that the highest rank was location duration and food ( = 4.37 SD = 0.67). The second was knowledge utilization ( = 4.33 SD = 0.66). The third was trainers ( = 4.26 SD = 0.65) and the lowest was knowledge and understanding ( = 4.13 SD = 0.72). Regarding level of average post-training satisfaction the highest was 4.44 for knowledge and understanding while the lowest was 4.16 for question and answer. For success of the project it was found that every biogas digester done by participants could produce biogas used in place of LPG and could reduce monthly expense by about 1400 – 1500 baht. The total construction cost of biogas production system was 58000 baht with a payback period of 4 years. For students there were 3 science projects about biogas; including 1) comparison of biogas produced from food remains and animal manure; 2) comparison of biogas produced from pigs and cows manure; and 3) comparison of biogas produced from dry and fresh pigs manure.

This research aimed to transfer technology about biogas digester construction and applying the biogas in household to teachers and students in Suksasongkhro Tak school. They were instructed and trained about biogas digester construction and applying the biogas produced from animal manure on cooking in household to reduce using LPG. The research operations were separated to 4 phases. The first was preparation and making understanding. The second was instruction and practical training. The third was monitoring and project evaluation. The last one was organizing the science project event. The number of participant teachers and students was 330. From the result of 5 scale questionnaire in project evaluation it was found that the evaluation about knowledge and understanding showed the maximum scale ( = 4.42 SD = 0.84). The second was about location duration and food ( = 4.36 SD = 0.75). The evaluation about the knowledge showed the lowest scale ( = 4.28 SD = 0.77). For the project evaluation of success it was found that every biogas digester done by participants could produce the biogas and it could be use to replace LPG and reduce expenditure about 1400 – 1500 baht/month. The total construction cost of biogas production system was 58000 baht. So the payback period was 3.22 years.

Traditional charcoal burning of rural people used husk kiln which had to use big piece of wood and get low quality charcoal. The objectives of this technology transfer were to provide training about 200 liters charcoal kiln invention and teach charcoal burning technique to villager in Tongfa district amphur Bantak Tak province. In the project materials that were used to build the kiln were given to 30 people in the village. The project had been separated in three phases preparing training and project evaluation. In training phase the villager was divided in 5 groups and all group used branches of eucalyptus that had the same sizes. The results of practical training were found that the best group got charcoal 0.75 sack and eucalyptus vinegar 2.3 liters by using 7.33 hours. After training questionnaire was used to evaluate satisfaction of participants. The statistical analysis results showed that Mean (x#) was 4.69. In the part of the success of the project it was found that found that participant could apply the khowledge the most. 58.06% of participant increased income 1001-2000 baht per month.
