Factor Affecting Elderly Consumer Testing on Thai Herb Ceramic Massage Product using Taguchi Design of Experiments
Get PDFThis study focuses on the OTOP (One Tambon One Product) Thailand product after selected group into five. Thai herb ceramic massage product was developed from statistic data selection previously. The experimental was decided for determination optimize consumer wanted as desirability value from using three nominal preference scales of performance, function and cognitive to create new response. Using a Taguchi design was used for design factors including the performance, function and cognitive. the experimental condition with full factional design 25 with 6 blockings was employed in the experiment for 6 samplings test as elderly 60-80 years old, males and females respectively consumers in northern Thailand in Chiang Mai. The result demonstrated that by using more ceramic, big ceramic size, Herbal ingredients #2, Fabric types #2 and Streamer to be heating source can optimize the desirability value for Thai Herb Ceramic Massage Product of 0.9 in the regression model with the optimizer method. Important factor is heating source, it was only significantly parameter to the response
Designing Quality Improvement and Economical Production Quantity: Application of Material Flow Cost Accounting and Cost of Quality
Get PDFMaterial flow cost accounting technique is a technique used to analyze environmental costs for the purpose of identifying costs in two parts: positive cost and negative cost. Which will be an indicator of the efficiency of the production process Because it affects the quality of products delivered to customers and customer satisfaction. There are also techniques. MFCA is used in conjunction with Cost of quality techniques to increase the confidence that products that are going out of the production process will have good performance. For the use of the design of the production process, find the size of the lot. Proportion of waste in production lot and number of shipments. The objective of the optimization problem is the maximum ratio of positive product cost to total cost (PC/TC). The researcher uses particle swarm optimization techniques to find the answer. which is the size of the product lot size, Number of product lot shipments and Proportion of waste in production lot in a serial multi-stage process. the results of MFCA analysis showed that the highest portion of negative product cost was material accounting for 53.29% and following by System cost of 4.75% comparing with the total product cost
Investigating the Effect of Rice Commodity Price Volatility on Provincial Capital Poverty: An Evidence from Indonesia
Get PDFPoverty is one of the macro problems faced by all countries. These problems have different solutions depending on the character of the poor population in the country. One of the proposed solutions is to control prices so that the level of public consumption is maintained. The purpose of the study was to analyze the effect of rice prices on poverty and to map the condition of rice price movements related to poverty in provincial capitals in Indonesia. This study uses panel data from 34 provincial capitals in Indonesia from 2011 to 2020. The data was collected from the Central Bureau of Statistics of Indonesia and uses a panel regression model and important performance analysis (IPA). The results of this study indicated that the price of rice positively affects poverty in provincial capitals in Indonesia. The IPA results show that most provincial capitals in Indonesia are in areas with low poverty rates accompanied by low rice prices and areas with poor people but tend to have high rice prices compared to the average price of rice. It concludes that rice greatly influences the consumption needs of the people of provincial capital cities in Indonesia. This finding shows the importance of maintaining the stability of rice prices due to the large influence of rice price movements on the increase in the percentage of poor people. Suggestions should be given for subsidized rice distribution in areas with high prices
