Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The purpose of this paper is to compare quality management certified and non-certified production companies regarding the production cost efficiency. A research carried out in 200 Palestinian production companies by means of questionnaires. The questionnaire was sent by email, and it was requested to be answered by production managers, the study use the independent t-test to test correlation between quality management and production cost efficiency. The certified companies significantly outperformed the non-certified companies with regards to waste elimination, production efficiency and better product quality. The subjective of data collection through production managers could involve risk of receiving biased response regarding the performance measure. Additionally, the research design by itself limited the results and findings on Palestinian context with no ability to generalize to other context.
Using Diesel Machine as a fuel in Indonesia is high enough. Therefore, The Goverment take the regulation to minimize the environmental pollution. One of PT Pertamina's environmentally friendly products is HSD 0.005%S, a diesel stripper product blended with a heavy kerosine stripper product in the Fractionator Hydrocracker Unibon. Therefore, an analysis is needed to increase the flow rate of one of the blending ingredients of the product, namely heavy kerosene. This research intended to obtain optimal conditions of light kerosene reflux flow rate and stripping steam diesel stripper mass flow rate on heavy kerosene products according to the specifications required by the multiple linear regression method. The prerequisite of this method is to test classical assumptions and test hypotheses on the data to be processed, then optimize the correlation coefficient (R2) so that the equation of the selected data line on the independent variable and the dependent variable has a "strong" connection. The line equation for the dependent variable specific gravity of heavy kerosene is Y1= 0,807 – 0,0002 X1 + 0,071 X2 and the line equation for the dependent variable of heavy kerosene product flow rate is Y2= 30,226 + 0,300 X1 – 33,205 X2. The optimum results of the reflux flow rate of light kerosene is 25,28 m3/hour while the mass flow rate of stripping steam diesel stripper is 0,2531 tons/hour. The optimal condition of the independent variable produces a maximum kerosene product flow rate at 29,41 m3/hour with a specific gravity of heavy kerosene condition of 0.8200.
