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.
One completion in complying the energy needs is to utilize Renewable Energy that is as the alternative to encounter the decreasing fossil-energy. Hydro Power Plant is the one that utilizes hydro as the source. Technically, there are three main components of Hydro Power Plant, namely kinetic energy, turbine, and generator. The turbine aims to convert the water-flow to kinetic energy through the rotor shaft. Archimedes Screw Turbine has used for this research hence it performs at each different for the low-head and zero-head stage. The flowrate that has the certain head stage can spin the turbine using generator to produce electricity. The concern of this research is to know how the scheming turbine can utilize hydro energy that is in reservoir and this aims to scheme the turbine. The research finding shows that the higher flowrate, the higher electrical power can be produced. The calculation results receive 9,4435watt for the lowest electric potential applying to 0,0030 m3/s for the flowrate, and 203,4246watt for the highest electric potential applying to 0,0641 m3/s for the flowrate. Thereafter, the scheming of the turbine specifically has a 0,1955 m for the diameter, 0,0586 m for the rotor blade and 0,2346 m for the pitch.
The electrical resistivity method (ERM) of the geophysical prospecting favoured by geoscientists, has become one of the most often used methods in hydrogeological and engineering geophysics. The ERM is a geophysical approach that provides a highly appealing method for characterizing subsurface formation over a vast region. Moreover, ERM is used to generate complete and persuasive results that are cost-effective, time-efficient, and data-rich which has been used in groundwater investigations in a variety of ways. ERM can also be applied in general stratigraphic mapping, well logging, seawater intrusion, groundwater pollutants, and estimation of overburden thickness This paper present a ranging review to highlight the usage of the ERM for groundwater investigation. The ERM results regularly give additional data to experts on numerous geophysical issues, for example, data on groundwater defilement, leachate, protective possibilities, and also to water supply sources within the environment.
One of the main parameters in planning the construction of bamboo mattress poles is the stiffness of the bamboo mattress. The elements of mattress stiffness are the moment of inertia of the mattress (Im), the modulus of elasticity of the mattress (Em), and the cross-section of the mattress (Am). This research will examine the rigidity element of bamboo mattresses. The research method used was to record physical data of general bamboo at random with a minimum outer diameter of 6.0 cm and a length of 5.0 m. The bamboo is assembled into a mattress with ties. The width of the mattress is 1.0 meter. Mattresses are arranged in 1 ply, 3 plies, and 5 plies. Each type of bamboo mattress is tested for its flexural strength until it collapses. The recorded data are load (P) and deflection (δ). The analysis was carried out to determine the relationship between the number of mattress layers and the stiffness parameter of the mattress. The results showed that there was a relationship between the number of layers of the bamboo mattress and the parameters of the stiffness of the bamboo mattress, with the equation: Y = 45958 X(0,3864); where X is the number of layers of the bamboo mattress, and Y is the flexural parameter of the woven bamboo (Em, Em.Im; or Em.Am).
