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 mass, dimension, and size of a gearbox have strong effect on the gearbox cost. Consequently, in order to minimize the cost of a gearbox, the optimization of the partial gear ratios should be found. This study targets to find the optimum partial gear ration of two-stage bevel helical gearboxes base on the objective function of minimizing gearbox cost. Nine main process parameters are adopted to probe their influences on the output response. A plan of simulation experiment is conducted to serve for finding regression model. It is revealed that the total gearbox ratio parameter, ug, has strongest impact on the response u1 when compared to those of others. Besides, the predicted values given by regression model are significantly consisted to experiments
Along with the development of technology, space weather activity becomes a very important thing in science. It’s caused by whether activity that occurs in space can affect the activities of life on the earth. Therefore, it’s important to be able to detect whether events in space, including solar flares. We believe that there has not been a single solar flare prediction study that did a prediction using PROBA-2 SWAP data, because flares are difficult to catch at that frequency. Nearly all previous researches have been focused on SOHO / MDI and SDO / HMI satellite. If the two satellites can’t capture the image for some reason, then PROBA2 SWAP satellite imagery can be an alternative. This research is aimed to implement image processing and machine learning methods on SWAP PROBA2 satellite imagery to predict event numbers of solar flare. The machine learning algorithm used is random forest, while the segmentation algorithm used is seeded region growing. This solar flare prediction research using SWAP PROBA2 satellite imagery produced the best f-measure value of 0.897
The development of Agropolitan areas require certain stages and the initial is identifying the superior commodities. This study, therefore, aimed to determine the superior commodity in the agropolitan area of Pasuruan Regency, East Java using the secondary data published by the Central Statistics Agency of Pasuruan Regency in 2017-2018. This research made use of land use analysis (land suitability analyses) as well as the district government policies to determine these commodities, LQ, and shift share analysis. The land suitability analysis shows the location of development superior product, LQ analysis showed the main plantation commodity is coffee and shift-share discovered those with fast growth include coffee and tobacco while land suitability found coconut, coffee, sugar cane, and tobacco. Furthermore, coffee was observed to have received support from the Pasuruan Regency Government in its development and the results from all the analyses indicate it is a superior commodity in the regency
This study was investigated the effect of the dual nano size particles on the AA7075-T651metal matrix. The nano size particles of TiO2 with 5wt% and variable weight percent of Al2O3 (10%,15%, and 20wt%) were used to reinforced the Al, using stir casting technique. It was found improving in mechanical and fatigue life. The microstructure was examined by Optical Microscopy, it has been noticed well distribution nano particles, leads minimizing the grain size of the parent phase, these effects improving the fatigue life by (3.5%, 7.7% and 9.7%) higher than the base metal and other composites, metal matrix Nanocomposites are having directly proportional relationship with percentage of Nano particle reinforcement
Tobacco has become a continuing problem in Indonesia, from field preparation, planting, trade, to the main product, namely cigarettes. Often, the government is faced with two-way problems to take a fairness policy, among public health, farmers' livelihoods, and tax revenue from the cigarette industry. However, the Corona Virus Disease 2019 (Covid-19) pandemic should be able to serve as a determination to meet domestic food and energy needs, while at the same time reducing medical costs that the government must provide. Therefore, we held a panel discussion with speakers including the Governor of Central Java, tobacco researchers from the Union, polyculture farmers, and tobacco farmer associations. The conference was also attended by representatives from the Ministry of Agriculture, the Ministry of Industry, the Ministry of Finance, and the National Development Planning Agency, as panellists. From the results of the discussion, we found that tobacco farming is actually not profitable because it is vulnerable to weather and bad trading management, but for a limited scale, this is still needed to compensate for clove farmers. To support food and energy security, a polyculture farming model can be applied as tobacco substitutes. Food crops which are also candidates for biofuel are proposed as new models of agriculture post Covid-19 pandemic
