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 inundation area of the Lempake Reservoir is currently almost 90% covered by water plants and there is very serious sedimentation in the reservoir. In several locations of the reservoir inundation there is piling up by residents, even in the right side of the reservoir has been piling up for the road body. The condition of the Lempake reservoir has decreased in capacity from year to year. At normal water level, the capacity of Lempake Reservoir in 2013 was 0.76 million m3 and in 2018 was 0.39 million m3. Therefore, it is needed an effort to control sedimentation in the reservoir, including by conducting studies on the sedimentation conditions of the reservoir, analyzing the sedimentation rate of the reservoir so that it can be seen the volume of sediment that must be dredged, so that it can reduce flooding that usually occurs in the location. The study was carried out by analyzing the volume of sedimentation in the reservoir by using the ArcGIS program and analyzing the flood discharge design at the site by conducting flood tracking at the Pasar Segiri River outlet point. The analysis results show that the capacity volume in 2020 is predicted to be 0.241 million m3 with an annual sediment rate of 0.074 million m3. From the analysis of the flood tracing in the Lempake Dam spillway, the flood reduction values obtained at the 1.01 year return period were 67.0% (scenario 1), 78.4% (scenario 2), and 80.8% (scenario 3).
Assessment of Irrigation Area (DI) Performance Index in Indonesia is carried out based on the Regulation of the Minister of Public Works and Housing Number 12 of 2015, along with the preparation of modernization of irrigation, the assessment of irrigation performance index needs to be adjusted to the readiness of irrigation modernization in various characteristics of Irrigation Area. The revision of the irrigation area performance index assessment in this study was carried out through the integration of the AHP Analytical Hierarchy Process statistical methods, Principal Component Analysis (PCA), Simple Additive Weighting (SAW), Ridge analysis, correlation analysis, and cluster analysis. Based on AHP and SAW methods, it is found that the index for DI with weir and dam infrastructure has different weights. This is a new finding, considering the characteristics of water sources and different operational needs. The modification of DI performance index determination that has included the water balance sub-aspects in the water availability aspect as part of the readiness to face future climate change, and the production sub-aspects in the management aspect as an indicator of DI successful management, are novelty in this study. The results of this index modification are proposed to be applied in locations in Indonesia, with differences in DI with weirs and DI with dams, as well as other records.
