The objective of this study was to develop a technique for detection of the water added in raw milk using Inter Digital Electrode (IDE) other than using conventional methods such as determination of specific gravity or of the freezing point temperature and the compression on frozen samples. The assumption capacitance value of added water in raw milk will be varied with the quantities of added water. The experiment was performed by using a LCR (GW INSTEK LCR-817) meter to measure the capacitance value of milk contaminated water from 0 to 90% and electrodes which are normal and ground of different electrode number (N) of 7 10 and 13 width (W) of 1 and 2 mm. and length (L) of 10 20 30 40 and 50 mm. Results shown that the capacitance value of the water added in raw milk were lower than the raw milk without added water. Additional the W1L50N13G (W=1 mm. L=50 mm. N=13 and grounded) detects the water added in raw milk with R2 of 0.9904

The objectives of this research were to study the information seeking method and problems of students at Rajamangala University of Technology Srivijaya Trang Campus the Faculty of Science and Fisheries Technology. The population in the study included 185 fourth year students who conducted a term-paper. The questionnaires were used to collect data and Cronbach’s alpha was 0.83. The data were analyzed by descriptive statistics (frequency percentage and standard deviation). The results showed as follows. Students rated that the university library was the Institutional information resource at the highest level. They mainly used the electronic resources. Students preferred to used the information written in Thai most. The modernity of information was mostly between 1-5 years. Students normally searched for the information 3-5 times a week. There were 3 main problems in seeking information: language was their barriers information was not matched with their needs and information resources were insufficient.

The purposes of this research were 1) to construct and evaluate the efficiency of the Computer Assisted Instruction (CAI) on Nuclear Physics class to have 80:80 effectiveness standards. 2) to compare learning achievement between pre-test and post-test scores after using the CAI 3) to study student’s opinion about CAI. Samples were the second year of Science and Technology students of the Rajamangala University of Technology Thanyaburi in 2011 academic year selected by simple random sampling. The first test was done by one-to-one evaluation and the second one by a small group in order to revise the CAI before implementing within the subject. The efficiency of the CAI was evaluated by experts both in content and production technique of the courseware. The results of this research were shown : 1) the CAI on Nuclear Physics contained the effectiveness at 87.00:85.33 which was higher than the standard criterion set (80:80) 2) the comparison between pre-test and post-test was found that the post-test score of students who studies with CAI were significantly higher than the pre-test score at .05 level and 3) the mean score of the student’s opinion about CAI was 4.35 shown that most of them satisfied the CAI on Nuclear Physics at good level.

The purposes of the study were to study the need competency and to develop the competency in information and communications technologies of teachers. The samples were 363 teachers of Rajamangala University of Technology Isan and 70 trainees of experimental group. There were 4 stages of methodology: 1) Study the basic information in order to analyze the need 2) Study the competency of ICT to analyze 3 parts of competency which were knowledge skills and features needed 3) Development preparation and 4) Training course development. The Tools were the questionnaire the achievement assessments of pre and post trainings and the evaluation of the training. The results revealed as follows: The need in information and communication technologies of teachers in 9 aspects was at the high level. The teachers training achievement is significantly different at the level of 0.05. After training the achievement is higher than before regarding the training course expectation teachers are satisfied with this workshop training at the high level. For the suggestion it should be follow-up continuously after training.

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.
