Clogging of Trash at the Micro Hydro-Power Plant can reduce the discharge, head, and micro-hydro production. Trash racks are currently less efficient in solving Trash clogging, so it needs appropriate technology innovation with the Horizontal Trash rack Diverter Trash (HTDT) which functions to get rid of or divert Trash. Diversion of Trash as well as increasing and stabilizing the discharge is important so that the innovation of adding a flow steering valve is needed (HTDT+V). The results of the research at β20° is the most optimal angle, the highest speed at the intake channel Cm4 V 0.7 m/s and HTDT + V β20° V 0.8 m/s occurs an increase in speed. Trash paste time β20° t 2.76 seconds, faster than the angle β0°, β5°, β30° Trash paste time t3.5 seconds. The HTDT+V installation increases the inflow velocity (V) in the intake channel by 60% and increases the discharge (Q) by 50%. - Grand Design for Merapi Irrigation Channel System Using Watershed and River Region Approaches based on Community Development in Yogyakarta, Indonesia

This paper proposes a grand design for Merapi Irrigation Channel, an irrigation channel system spanning from Turi to Cangkringan District in Yogyakarta, Indonesia. This design is based on Geographic Information System research to assess the feasibility of the system from two aspects, namely geophysics using site selection approaches (watershed and river region) and community aspirations, analyze potential water resource availability to support its sustainability, and construct a grand design. Primary data acquired from IKONOS image interpretation were used to collect geophysical and ?eld data for parameter mapping, and spatial data were modeled using Geographic Information System technology to determine paths, directions, and routes. Community aspirations were obtained by structured interviews with key informants and focus group discussions with community groups in village units. Results showed that the land carrying capacity geophysically allowed Krasak–Bedog Rivers as the permanent discharge of 123.78 m3/s of water, which is consistent with community aspirations for high irrigation water discharge in traversed districts. Overall, 19 rivers and 9 arti?cial retentions in the channel system respectively produced maximum discharges of 123.78 and 12 m3/s. The grand design included the construction of a 41 km long Merapi Channel from Turi (speci?cally Wonokerto Village) at 500 masl to Cangkringan (Glagaharjo) at 450 masl. - Stage of potential identification irrigation channel topography analysis for micro-hydro power in the Kalibawang irrigation primary channel, Yogyakarta, Indonesia

This study was designed to determine the stages in the identification of micro-hydro in irrigation channels based on the classification and level of data requirements in a project, starting from the initial study, feasibility study and detailed engineering design. The study was conducted with site selection criteria using four information systems and technology tools, namely Google Earth, GIS Topography, UAV Drone Phantom DJI 4, and Nikkon DTM 332 Total Station. The results shows through GE and GIS, obtained 23 potential points, 7 of which are high potential, followed by field measurements with 1 selected UAV location Cascade, and detailed with TS to produce Head (H) 12 m, with CM and FDC probability 75% discharge (Q) 5.5 m3/s, generated power (P) 550 kW. This study provides a method and solution for speed in identifying potential with Google Earth and GIS (Macro Class), speed and risk reduction for surveyors with UAVs (Mezo Class), and accuracy and detailing at selected locations with Total Station (Micro Class). So that this research provides accuracy in the stages, methods and tools used in the identification of micro-hydro potential in irrigation channels. - The Potential of Micro-hydro Power Cascade in Irrigation Channel of Kalibawang, Indonesia

Estimation of the energy demand in Indonesia will increase by 8.15 % annually until 2030. Indonesia is committed to preventing climate change through mix energy (new and renewable energy). One of the sources of this energy is waterpower plants with a potential of 75 091 MW have been utilized 6.4 %, mini-hydro, and micro-hydro with a potential of 19 385 MW have been utilized 1 %. In the Industrial Revolution 4.0, it is doable to identify such potential using drone. This study was conducted in the Kalibawang irrigation area, Special Region of Yogyakarta, Indonesia. The procedure starts with the generation of detailed Aerial Photography using Drone DJI Phantom 4. The images from aerial photography were then processed into high-resolution Digital Elevation Model (DEM). DEM data represent the study area topography and can be used to identify the stream gradient potential or height difference (H). Six potential points were identified with height differences between 3 m to 8 m, resulting in the potential generated power ranging from 125 kW to 334 kW. This study demonstrates the identification of micro-hydro energy potential points, height difference, and generated power using Drone. Six points were identified with total potential energy 1 418 kW.
