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 use of micro hydro power plants (PLTMH) in utilizing existing water resources has been widely carried out, especially for people in rural areas who experience difficulties in accessing electricity networks and are spread throughout Indonesia. One of the rivers in the province of South Sumatra, Indonesia, which has a swift flow of water to be able to drive a turbine is the Kelekar River located in Ogan Ilir district. Besides having a quite heavy flow of water, Kelekar River is supported by the presence of the reservoir basins that is Embung of Sriwijaya University which has an overflow design be equipped 2 sluice gates with dimensions of 2 x 1.5 m and width threshold with top point elevation +6.00. This study aims to calculate the initial design of micro hydro power plants on the Kelekar River based on the river flow rates and the height of the water falling. Stages of analysis include rainfall analysis, test the suitability of data distribution, calculate concentration time, determine runoff coefficient values, calculate runoff discharge and calculate the height of the water falling, initial design analysis of micro hydro power plants. Based on the calculation analysis, it is obtained that the flowrate of the kelekar river is 211.109 m3/sec (QRmax) and 15.732 m3/sec (QRmin), design discharge (Qd) = 0.45m3/sec, the high of effective energy (H) = 3.475792 m, power from water flow 15.344 kW, dan the power produced by the turbine is Pt = 11.508 kW with the turbine efficiency t = 0.75
This study aims to obtain determinants of the parameters of the index performance of groundwater irrigation in the karst mountainous regions. Determination of the value of performance index of groundwater irrigation systems is based on technical aspects and non-technical aspects by analyzing the variables that give effect to each of the aspects both technical and non-technical. The method used in collecting data for technical variables was direct measurement of site visit and secondary data from the field. The non-technical aspects of using questionnaire data as qualitative data were converted into quantitative data. Filtering of variables was done with the smart PLS-Partial Least Squares tool. Then an analysis was carried out using the GRG-Generalized Reduced Gradient method to solve the non-linear equation with the objective-objective assumption and constraints. The model calibration test was calibrated and simulated on the parameters used. The results of the study were in the form of a performance index model to measure the level of success in developing groundwater irrigation systems in karst mountainous regions. The performance index evaluation of the developed groundwater irrigation system was an accumulation of technical indexes and non-technical indices involving influential variables
