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.

There are 92% of house buildings in North Sulawesi Province in Indonesia uses zinc as the roofing material. The use of solar panels as an alternative energy source can also be used as an outermost layer of roof covering as heat retention; the largest and longest part exposed to direct sunlight. The problem facing house buildings in humid tropical climates is the excessive heat that often occurs due to the accumulation of solar radiation on the roof that propagates directly into the indoor. The study aims to find the using solar panels placed on corrugated zinc roofs as an outer layer to cut the heat accumulated on the roof surface and propagate to the indoor of buildings. Two similar test cells have been built; where on the roof one of the test cells put solar panels while other cells without solar panels. Measurements of roof surface temperature and air indoor temperature on the test cells show a significant effect of the placement of solar panels on zinc roofs. A test cell that has solar panels, its roof surface temperature is below the 5 °C average and its interior temperature can be maintained lower than the temperature on the cell without solar panels. Further research on the production capacity of electricity from solar panel systems is still necessary, as a renewable energy source
Sipunculus nudus has become an important factor for society as a traditional medicine because of its nutritional content. The research objective is to determine the chemical composition, profile of fatty acids, and groups of chemical compounds in S. nudus. S. nudus samples were taken in Waworope Village, North Wawonii District, Konawe Kepulauan Regency, Southeast Sulawesi, Indonesia. The results of proximate analysis of S. nudus are ash level of 7.65%, water level of 8.34%, protein level of 54.22%, fat level of 10.31% and carbohydrate level by 19.47%. Content of Saturated Fatty Acids identified were caproic acid, capric acid, lauric acid, myristic acid, and palmitic acid, while Polysaturated Fatty Acid identified were linolenic acid, eicosapentaenoic acid, docosahexaenoic acid. The chemical group S. nudus ethanol extract identified were alkaloids, tannins, flavonoids and saponins
