This 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.

. In this study examination of label information physical and microbiological qualities was 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.

This research study analyzes the problem of waste water from the burning of palm trees which are used as fuel for power generation of palm ash. It is used to ferment biogas as a fuel for power generation where a large amount of wastewater from the gas digester is completed. The wastewater is then pumped out of the gas digester. Biological in large quantities Therefore to study the analysis of wastewater to find a method for designing a wastewater treatment system from high voltage systems from the corona discharge principle when adding ozone it is necessary to analyze the chemical effects of the wastewater according to the standard values of the Department of Industrial Works.
