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.

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
This research intends to investigate the existing run-off coefficient based on the land use in the area of Batur, Bratan, Buyan, and Tamblingan Lake (Bali, Indonesia). The value is used for knowing how big the run-off volume that has to be reduced so there is no flooding in that area. The methodology consists of overlaying the land use map and then multiplying it with the run-off coefficient The run-off coefficient is as the function of design flood, rainfall intensity, and land use. The result shows that the run-off coefficient of Batur Lake is 0.37; Bratan Lake is 0.38; and Buyan Lake is 0.36. However, the run-off coefficient mean is 0.37
