The biogas production and the application of lunch project for student at suksasongkhro tak school tak province

Abstract

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 1,400 – 1,500 baht. The total construction cost of biogas production system was 58,000 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.
