The study on perception towards service quality of Siam Kraft industry Company Limited was aimed to investigate and compare service quality perception of Siam Kraft Industry Company Limited. The survey was accomplished among 207 Siam Kraft industry Company Limited customers as the sample group. The questionnaire with the reliability value of 0.97 was administered as the instrument for collecting data which were analyzed by the frequency distribution percentage distribution standard deviation t-test One – Way ANOVA and Scheffe. In case of 0.05 statistical differences was found Least Significant Different method was applied to verify each pair. The results revealed: 1. According to the respondent’s’ general information 140 were females (68.60 %) 92 people aged ranging from 30 to 40 years old (44.45 %). 124 or 59.90 held bachelor’s degrees and 69 people or 33.33 % had 5 to ten years work experience. 2. The perception towards service quality of Siam Kraft industry Company Limited in the overall was relatively high. When looking into each aspect the first item was credit service followed by finance delivery processed products and marketing services respectively. 3. As for the respondents ‘general statuses different ages and work experiences did not perceive service quality of Siam Kraft industry Company Limited differently at 0.05. However males and females perceived different marketing service; and different educational levels perceived processed products differently at 0.05.

This research aimed to determine the optimal sand mold mixture’s ratio by using return sand bentonite water content and new sand component. Then the properties of the mixture according to the standards of American Foundrymen’s Society include the ability of compactability moisture content permeability and green compressive strength. This study applied mixture experiments and response surface methodology to determine an optimal sand mold mixture components condition. After the experiment and linear programming it indicated that the condition was at return sand (95.5387 %) bentonite (1.130102 %) water content (2.331196 %) and new sand (1 %). The green sand mold has compactability (58.37923 %) permeability (73.80148 %) moisture 6.5 % and green compressive strength (0.53 Kg/cm2). At this condition the cost is 11.31579 baths per kilogram.

This research is aimed to developed and evaluate a competency model of production engineer in the automotive industry. The data is collected from Amata City Rayong. The research is performed with two steps: 1) create an engineering competency in the automotive industry using Delphi technique with 17 experts. Then 2) review the engineering competency with the focus group of management staffs from automotive industry in Amata City Rayong. The statistics used in the analysis were percentile median and inter-quartile range. The results show that competency is consist of three parts. Part 1: management competency Part 2: functional competency Part 3: production engineering characteristic and consisted of four parts 1) the management of operational performance 2) production engineering 3) engineering knowledge 4) personal characteristics. Examining results in the competency model of production engineer in the automotive industry: the data is collected from Amata City Rayong created are appropriate and feasible in practice and performance as a performance model is built according to expert opinion.

This paper presents an assessment of the quality of electricity transmission and distribution system to supply power to the industrial area. The objective is to analyze the power quality that customer in the industrial area need high level. By analyzing the power quality of Provincial Electricity Authority (PEA) in transmission system 115 kV distribution system 22 kV and 400/230 volt in Rojana industrial park from power quality meters. The study concluded that the phenomenon occurs continuously consist of RMS voltage power frequency voltage unbalance short term flicker long term flicker Harmonic meet the standards applied to all. The phenomenon occurs temporary consist of transient voltage dip voltage swell interruption in the conclusion the power quality problems caused by voltage dip most especially with loads which are sensitive to voltage. From the moment the measurement showed that the voltage dip on transmission system 115 kV maximum of 19 times. The voltage dip that occur including three voltage level of 30 times there are events that do not pass SEMI F47 standard 12 times or 40%.

This research objective is the Factors influencing the successful strengthening of supply chain management-oriented cooperation in export of Halal meat processing industry of Thailand to ASEAN countries. Examined the congruence of this model with empirical data which used quantitative research methods. Findings are us follows: (1) The factor of external (2) (3) The factor of cooperation (4) The factor of Halal logo (5) The factor of Halal quality (6) The factor of competitive advantage positively affected the successful strengthening of supply chain management-oriented cooperation in export of Halal meat processing industry of Thailand to ASEAN countries. But the factor of internal no positive effected. affected the successful strengthening of supply chain management-oriented cooperation in export of Halal meat processing industry of Thailand to ASEAN countries
