Phisit Triworawet — 2024-12-29

This research focuses on the design of a PLC experimental setup for controlling three-phase motors to facilitate practical learning in the subject of industrial motor control. The experimental setup comprises five worksheets: 1) Control of a 3-phase motor with time delay stop, 2) Control of a 3-phase motor starter circuit with time delay, 3) Control of a 3-phase induction motor with automatic switching, 4) Control of a 3-phase induction motor using the star-delta method, and 5) Control of a 3-phase induction motor with automatic sequencing. A sample was 20 undergraduate students of Bachelor of Electrical Engineering, Pichayabundit College. The satisfaction evaluation results found that the average evaluation score for the quality of the experimental design was 4.858, which is at a very good level. Additionally, the average evaluation score for the experimental kit manual was 4.88, also at a very good level. This experimental setup allows learners to apply their knowledge effectively in controlling motors in real industrial applications.

A study and Development of processed bag products from krajood for men in the Generation Y Baan Kawee Basketry Map Lao Cha-on Klaeng District Rayong Province

phanom chongkon — 2024-12-29

The purposes of this study 1) to study the woven sedge handicraft of Ban Kawi, 2) to design and develop clothing accessories from the sedge handicraft of Ban Kawi, Map Lao Cha-on, Klaeng District, Rayong Province, with 3 populations and samples as follows: 1) Key informants: the president of the Ban Kawi Weaving Group, Map Lao Cha-on, Klaeng District, Rayong Province 2) Men's bag consumer group on the Facebook page for Generation Y men, 88 people, using accidental sampling. The tool used by the users is a questionnaire to use the data as a guideline for product design. 3) A group of 3 product design experts. The research tool used is an evaluation form by product design experts. The data is analyzed as satisfaction scores from experts. The data is analyzed using statistics of mean, standard deviation, and percentage. The scoring criteria are set as a 5-level evaluation scale to evaluate the data from the questionnaire and find a conclusion that can be used as a guideline for design. The results of the study found that the data obtained from the interview form of the president of the Ban Kawi Weaving Group revealed the need for product development. The study studied information on the concept and process of designing woven handicraft products using weaving patterns with community participation. The results of the consumer sample survey found that when choosing a bag, the price, brand, shape, size, pattern, black tone, and durable material were taken into account. The results of the survey selected the type of bag that was appropriate for the usage. The researcher designed the bag based on the needs of the consumers. One collection was designed, consisting of 5 items: a large shoulder bag, a small shoulder bag, a tote bag, a crossbody bag, and a wallet. The main color tone was black. The materials used were black fabric and leather. The weaving pattern was a two-tone black and white alternating pattern. Silver accessories were used to be consistent with the Quiet Luxury trend (VOGUE, 2021). Three collections were designed, consisting of 5 items, and one collection was selected, adjusted according to the suggestions of experts, to be used in the production of a prototype. The evaluation results of the draft of the bag design made from sedge for Generation Y men found that the draft with the highest evaluation score was the draft of Collection 2, which was evaluated at a very appropriate level with an average score of 4.53 and a standard deviation of 0.69.

Fish Dad Deaw Oven Using Hybrid Solar Dryer Combined Heat and Infrared Drying

teerasad kanasri — 2024-12-29

This research study investigates the utilization of solar thermal energy combined with infrared radiation for a drying machine, designed for continuous drying processes. The structure of the drying system is a parabolic shape measuring 2.0 meters (L) x 1.2 meters (W) x 1.0 meter (H), equipped with four medium-wave infrared lamps operating at a wavelength of 2-4 micrometers and consuming 1,000 watts of power each. The experimental procedure began with the preparation of 3,811 grams of freshly cleaned snakehead fish, which were dried at a temperature of 50 degrees Celsius. The drying process was compared with natural sun drying on clear days, utilizing solar thermal energy until the fish reached a moisture content of 54% (wet basis) after 5-6 hours of drying time. The results indicated that drying the snakehead fish at 50 ºC for 3 hours achieved a standard moisture content of 50.42% (wet basis). When using hot air generated solely from the solar drying machine, the thermal efficiency of the drying process was found to be 5,229.96 kJ/kgH₂O evaporated, representing 66.2% efficiency over a drying period of 240 minutes. In contrast, when combining hot air from the solar collector with infrared radiation, the thermal efficiency improved to 9,090.02 kJ/kgH₂O_evap accounting for 40.56% efficiency in a drying time of 180 minutes
