Get PDFวารสารวิชาการและวิจัย มทร.พระนคร, ปีที่ 15, ฉบับที่ 2 (ก.ค.-ธ.ค. 2564), หน้า 103-118This study aimed to use Poka-Yoke techniques to help prevent errors and reduce loss in Front Side Fender Model assembly process. The researchers used four tools in the 7QC tools which were Check Sheet, Cause-and-Effect Diagram and Graphs to search for causes and ways to solve problems and Cause and Effect Matrix and ECRS Techniques. The study revealed that the main cause of the problems was that the incorrect assembled side fenders were submitted to another department. This mistake had bad effects on time and workforce spent for correcting work including more expenses. The mistakes occurred because there was no tool for detecting errors in the work piece. Therefore, the researchers use Poka-Yoke techniques in order to decrease errors by designing a control system for target detection while it was moving through the process. After collecting data, the study showed that before the improvement during January to August 2019, the number of problems caused by the process were 0.093. However, the number of problems after the improvement during September to December 2019 reduced to 0. It was obvious that this improvement reduced the loss from the front side fender assembly process up to 100.Rajamangala University of Technology Phra Nakho

dyed fabrics that are produced and sold in Sakon Nakhon Province. Effect of moisture and pH of
indigo dyed fabrics on bacterial growth were also determined. The result of the study shows inhibition of S. aureus TISTR 746 and E. coli TISTR 073 by agar diffusion plate test, all samples could inhibit Saureus TISTR 746 (accounted as 100%), and only 9 samples could inhibit E. coli TISTR 073 (accounted as 56.25%). Whereas, the study of antibacterial activity by AATCC test method 100-2004 at 24 hours was found that the natural indigo dyed fabrics code A3-1 could inhibit both bacterial strains in the highest level. The result also shows the effect of moisture and pH of indigo dyed fabrics on bacterial growth, it was found that the increased humidity levels of indigo dyed fabrics have effect on the reduction of the inhibition efficacy of both strains. While indigo dyed fabric with pH 3.0 was found to inhibit most of the growth of both strains. In addition, images obtained using a scanning electron microscope (SEM) could clearly confirm the property of indigo dyed fabric on inhibition of S. Aureus TISTR 746 and E. coli TISTR 073.Rajamangala University of Technology Phra Nakho

performed in 30 clear-plastic and 3 opaque-plastic bottled drinking water products distributed in city municipality of Ubon Ratchathani. Results showed that 12 clear-plastic (36%) and 3 opaque-plastic (9%) bottled drinking water samples had no expiry date on the product labels, which were discordant to the criteria for drinking water in sealed containers imposed by the Ministry of Public Health of Thailand no. 383 (2017). Odorless appearances of all drinking water samples were observed. Values of pH in 4 clear-plastic (12%) and 3 opaque-plastic (9%) bottled drinking water samples were in the ranges of 6.21±0.00–6.29±0.03, which were below the allowable limit (pH 6.5–8.5). All bottled drinking water products contained numbers of total coliform and fecal coliform bacteria less than 2 MPN/100 mL and were devoid of E. coli. Therefore, based on the quality of clear-plastic and opaqueplastic bottled drinking water products distributed in city municipality of Ubon Ratchathani, 1 5 samples (45%) did not meet standard for drinking water in sealed containers declared by the Ministry of Public Health of Thailand (1981 and 2017) owing to no expiry date labeled on the products and pH value below 6.5.Rajamangala University of Technology Phra Nakho

Get PDFรายงานวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2563The objective of this research was to study of rotary drying of high-moisture long pepper by using a combined hot air and infrared radiation. The experiment was carried out at the drying temperatures of 80, 90 and 100 °C, infrared power level of 500 W, hot air velocity of 2.5 m/s and rotary revolution of 3, 6 and 9 rpm. In this study, two patterns were examined by the different drying conditions, namely 1) hot air drying and 2) combined hot air and infrared radiation drying. The effects of above drying parameters on the change in moisture content of long pepper and specific energy consumption (SEC) of the drying system, were investigated. The results showed that the combined hot air and infrared radiation drying was shorter drying time than hot air drying. The lowest total SEC during drying process of 26.77 MJ/kg water when the drying temperatures of 80 °C, infrared power level of 500 W, hot air velocity of 2.5 m/s and rotary revolution of 3 rpm were used.Rajamangala University of Technology Phra Nakho
