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.

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
One of a major problem in electro discharge machining is the formation of the recast layer, which causes hard, brittle and micro cracks layer from the high temperature during machining. This article was focused on the method of reduces the thickness of layer damage of high speed steel work material by using a composite tool from copper-silver instead of copper tool. An experiment was carried out using a copper – silver composite tool and pure copper tool. The machining conditions included the use of the pulse current and pulse on time as input parameters. The morphology, microstructure of white layer was characterized by scanning electron microscopy. The results showed that the surface quality of high-speed steel after EDM with copper –silver composite electrode and copper electrode are dissimilar. In this case, EDM using composite electrode the recast layer thickness from pure copper electrode were reduced from the maximum value 14.56 μ m to 3.28 μ m moreover experiments showed improvement of micro hardness value from (297.1 to 193.6) Vickers of surface layer compared to the pure copper electrode
