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 study aims to investigate the mediating role of supply chain financing on the relationship between negotiation, collaboration, and digitalization with the supply chain effectiveness of Alfamikro partners. The study involves 261 owner micro-retailers of Alfamikro partner members in the Tangerang area as respondents. The study employs the Structural Equation Modeling (SEM) analysis technique with the help of the AMOS program. The results showed that there was an influence supply chain finance on supply chain effectiveness in the Alfamikro program. Collaboration and digitalization affect supply chain financing, but negotiations do not influence the supply chain financing. The study also found that supply chain financing mediates in increasing the effect of collaboration and digitalization on supply chain effectiveness. While supply chain financing does not mediate the relationship between the negotiations and supply chain effectiveness, therefore, micro-retailers and their suppliers can build strong relationships through collaboration and digitalization. Micro-retailers can engage suppliers to work under strategic alliances through cooperation, and digitalization
The utilization of biomass briquettes used as an alternative fuel can replace fuel oil, especially kerosene and gas, which has not been very effective in its journey because several factors influence it. Therefore, it is important to improve the stove, which functions to transfer heat from biomass briquettes to make the cooking quality more effective. So this study aims to utilize coconut shell waste briquettes as fuel on a stove whose combustion chamber is modified by varying the diameter of the aluminum cylinder. The results showed that the variation of the cylinder diameter 180mm was the most superior in terms of fire temperature, water boiling ability, and thermal efficiency of 514oC, 30 liters, and 37.74%.
Low alloy steels are particularly used in the manufacture of several products such as storage tanks, oil and gas pipelines, industrial equipment and many agricultural and construction machinery parts that may experience service failure, and thus may require repair through welding processes. The weldability of steel is determined by its susceptibility to cracking, which can be prohibited by using certain welding procedures, which are often costly and difficult to use. Submerged arc welding of low alloy steels (AISI 5147) was implemented, firstly without nickel additives, followed by adding nickel to powder flux with a wide range (10, 20, 30, 40 and 50 wt. %). X-ray Inspection, tensile test and energy dispersive spectrometer were then utilized to evaluate the resulting welds. Results revealed that the tensile strength and weld joint efficiency were reached to (845 MPa) and (112 %) respectively when 20 wt. % of nickel was added to flux
Garlic (Allium sativum L) is one of the horticultural plants in Indonesia that is used to enhance the taste of food and medicine to cure various diseases. During the heating process, the content of anti-oxidant active substances in garlic will increase along with the heating process, one of the antioxidant compounds in black garlic is polyphenol compounds. The purpose of this research was to obtain the value of water content and pH in the process of produced Black garlic, to obtain the best heating time for Black garlic in terms of the total polyphenol content during the heating process, and to obtain the optimal time for the extraction process of Black garlic the using ultrasonic method on the concentration of total polyphenol content. The results showed that The effect of heating time will affect the water content and pH of Black garlic products with a regression value of R2 = 0.9965 for water content and R2 = 0.9953 for pH. The heating time of Black garlic will increase the total polyphenol content with a regression value of R2 = 0.9758. The results of the hedonic test of the best Black garlic products based on the taste aspect are 85% of respondents and the ease of consumption is 70%, namely on heating for 14 days. The best total polyphenol content in the extraction time variation was 15 minutes with a polyphenol content of 946.87 mg/kg.
TiO2/Ti electrode preparation has been carried out by anodizing, sol-gel and dip coating methods while tellurium coating has been carried out using the dip coating method to obtain Te-TiO2 / Ti electrodes. Photo current response of TiO2 / Ti and Te-TiO2 / Ti tested on photoelectrocatalyst shows that TiO2 / Ti electrodes are active in UV light and Te-TiO2 / Ti is active in visible light. The results of characterization using XRD showed anatase crystals, SEM showed nano tube crystals against Te-TiO2 / Ti electrodes, EDX confirmed Te on Te-TiO2 / Ti electrodes, with a percentage of 2.48%. Measurement of UV-Vis Diffuse Reflectance Spectroscopy (DRS UV-Vis) was done to determine the band gap energy of the prepared TiO2/ Ti and Te-TiO2 / Ti electrodes, LSV shows that the TiO2 / Ti electrode is active in UV irradiation and the Te-TiO2 / Ti electrode is active in Visible light. The results of the UV-Vis spectrophotometer analysis that degraded the reactive blue 160 compound by photolectrocatalyst showed that the TiO2 / Ti electrode was active with UV light irradiation with a degradation rate constant of 0.0289 minutes-1 and active Te-TiO2 / Ti with visible irradiation with a degradation rate constant of 0.0653 min
