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.

This article analyses the sustainable water supply models adopted by rural community groups, considering the social, economic, technological and ecological sources. Furthermore, distribution performance, institution, and sustainability were examined using survey, observation and interview methods, and the data obtained were analyzed using WarpPLS, with all predictor variables and sustainability criteria in a condition that is not good. Therefore, it was established that the social factors, technology, ecology of water sources, and the performance of drinking water distribution indirectly affects the sustainability of supply, by the mediating institutional factors, which together with economic and ecological factors tend to directly influence sustainability. In addition, ecological factors exhibited the greatest total effect, and institutional factors strengthened the community role, in efforts to improve the environmental conditions of water resources. In conclusion, the ecology of water sources and institutions was identified as the most influential variable on the supply sustainability, while the distribution performance variable confers an indirect effect, through institutional mediation
Small-Medium Enterprises (SMEs) of batik involves chemicals that an enhanced potential in environmental impact due to the limitation in resources to pursue production. Therefore, this study aims to analyze the environmental impact and determine the Eco-Efficiency Index (EEI) from batik production using the eco-efficiency method. The results showed an environmental impact of 0.20571247 DALY on the human health factor, 203994.79 PDF*m2yr on ecosystem quality factor, and 94449.809 MJ surplus on resources factor. Furthermore, the impact on the environment caused a total eco cost of IDR. 4,769,679,764.48 and EEI of 0.0039, that indicates the industry is affordable but not sustainable. Hence, proper material management is expected to possibly improve the situation and reduce the use of raw materials, which is achievable by recycling items in the nature of wax, water and coloring
