Oil spills in every household caused by cooking are difficult to eliminate when accumulating for a long time. In this study the researchers aimed to develop the remaining coffee grounds for oil absorption. From 2 coffee ground samples types A and B obtained from different coffee shop & coffee grounds type A demonstrated more effective in absorbing vegetable oil. The sample A was thus treated with hydrogen peroxide (H2O2) solution at the concentration of 0.5 1 3 33 50 80 and 100 percentages for 30 minutes and determined for the efficiency in oil elimination. The sample with at least 80 % (v/v) H2O2 showed the most effectiveness in absorbing oil. The coffee grounds that were later treated with pineapple juice fermented Kefir could help increase coffee ground degradation at 51.07 percentages. The Kefir treated coffee grounds packed in an absorbent bag revealed higher effectiveness in oil absorption at least 51.07 percentages compared to the controls that were cotton bag and coffee a harboring at the percentages of 73.85 and 30.04 respectively. This coffee ground bag after thrown into the ground could be decomposed in nature for 52 percentages within 1 month. Due to the oil elimination properties of the coffee grounds that are environmentally and human friendly as well as low cost it is possible to develop the kefir treated coffee grounds for being oil-absorbing products that can come in contact with human skin.

The purposes of this study ware to reduce travel documentaries: Conquer the Forest and to study the satisfaction toward travel documentaries: Conquer the Forest. The data collected from 100 people who was tourism visiting at Thong Pha Phum District Karnchanaburi province. The statistics to analyze data employed frequency percentage mean and standard deviation. The results of the study showed that the satisfaction of tourism to travel documentaries: Conquer the Forest was at a high level (x ̅=4.17).

The objectives of License documentary were to create conscious mind and showed how violation of copyright do in Thai society and to study the satisfaction survey form 100 people by using online questionnaire. The statistic to analyze were frequency average and standard deviation. The result found that audience had the satisfaction to License documentary at a high level (𝑥̅=4.08).

The objectives this special project were to produce the Chao Phraya Cruise 3D Motion Graphic media and to study about the satisfaction of the audiences who watched Chao Phraya Cruise 3D Motion Graphic which the target was 100 of foreign tourists and Thai Tourists. Under this study the statistics used for analyzing the data were frequency percentage average and standard deviation. The study indicated that the samples were satisfied with the Chao Phraya Cruise 3D Motion Graphic about content was at a high level (= 4.41 S.D.= 0.66) and about quality was at the highest level (= 4.63 S.D.= 0.58)

The objectives of this research were to develop of transmission line calculation program based on usage and frequency consisting of the two-wire transmission line twisted pair transmission line and coaxial transmission line. The program was developed in the form of graphical user interface in Malta. The developing and testing results found that the program was correctly capable to calculate capacity conductance inductance resistance and impedance for each transmission line usage and frequency. The results from the program with black box testing by five experts and twenty system users found the average and the standard deviation of results form computer experts were 4.04 and 0.36 respectively while those of results form the system users were 3.88 and 0.48 respectively. Conclusion it showed that the efficiency of the calculation program was a high level and can be used as a teaching and learning as well.
