Abstract

Geological characters analysis is essential for micro hydropower plant (MHP) development planning. This paper presents an analysis of the geological aspect to determine the layout of MHP components based on remote sensing data as part of a solution to addressing power shortages in Sungai Are District, South Ogan Komering Ulu Regency, South Sumatra Province. Remote sensing and topographic map were extracted to identify the potential site. The topographic map and geological analysis were used to calculate the potential of electrical energy and the geological hazard risk, particularly floods and landslides. The results of the study identified four potential sites. Site 1 (Luas River, Ulu Danau Village) and site 3 (Putih River, Gintung Village) are suitable for MHP with a low cost of construction. Site 2 (Pecah Pinggan Village) and site 4 (Simpang Luas Village) are prone to flooding and landslides that makes it suitable for MHP but with a high cost of construction. Based on the geological aspect analysis, it is possible to optimize the hydropower capacity, by adding the volume of water flow from several nearby tributaries channeled into the hydropower flow system through civil construction engineering or by making a cascade design on the tailrace water flow.

Abstract

Morphology in South OKU District is the potential of a micro hydropower plant (MHPP) as an alternative power source. This potential has not been fully utilized, although many un-electrified villages are in several remote areas. Identification planning for MHPP is one of the most critical planning tasks and requires excellent multi-criteria spatial analysis. GIS and multi-criteria analysis have played an essential role in analyzing suitable locations for MHPP development. GIS and multi-criteria spatial analysis consist of detailed investigations of ongoing sites and suitability for specific planning. This research aims to overview GIS multi-criteria spatial analysis for MHPP site suitability based on electricity South OKU demands. The most critical data and criteria to decide the best site suitability are un-electrified villages, rivers, land use, slope, landslide vulnerability, and elevation. All of the data were generated into the raster data format. Quantitative modeling used AHP as a multi-criteria analysis method, and a weighted score is determined by considering the comparison of each criterion. Finally, the criterion layer was calculated by open-source QGIS to create a site suitability map. The field study verified the resulting map, and there is a match between the preferred locations and the field survey. The research results preferred Sungai Are, Sindang Danau, and Kisam Tinggi Sub-district as the best suitability for MHPP development.

Abstract

Remote sensing technology has been widely applied in various fields, including oil, gas, and mineral exploration, spatial planning, and environmental monitoring. This paper describes the application of remote sensing technology for the potential study of a renewable micro hydropower plant (MHP) using Landsat 8 satellite data. The Sukaati Watershed, West Java, Indonesia, was selected as the case study area. Landsat 8 satellite data, acquired on August 21, 2020, was applied to extract information on land use, geology, and potential landslides. Drainage patterns, watershed boundaries, and head height were obtained from topographic map data. Drainage patterns, watershed boundaries, and land use are used to calculate flow rates. Geological map and landslide are the basis of layout of MHP components, such as water intake, dam, waterway, settling tank, penstock, and powerhouse. A field survey to acquire actual flow rate and head height was conducted to validate the results of the remote sensing data interpretation. Two potential sites of MHP were selected with a hydropower design of 129 kW and 5.18 MW. This study showed that remote sensing technology is beneficial for studying the potential of MHP because fieldwork can be done more quickly and efficiently.

Abstract

The north coastal Java located in the West Java, especially in Cirebon, Indramayu, and Subang, occurs loss and forming new land by abrasion and accretion processes. Observation using satellite imagery can be used as an initial stage to determine the distribution of abrasion and accretion around the north coastal area. Observation of land changes was assigned using Landsat imagery from 1978 to 2020. The result shows that inland change was controlled by abrasion and accretion. It is occurred in Indramayu and Subang, especially in several areas around large rivers e.g. Cipunegara and Cimanuk Rivers. Estuary changes in the Cipunegara and Cimanuk Rivers were controlled by the high flux sediment deposition of the river mouths affecting the new land forming due to the accretion process. Monitoring through Landsat satellite imagery on the Cipunagara River from 1978 to 2020 shows that there was 205 Ha of new land. Remote sensing analysis in the Cimanuk River area shows that the estuary line from 1978 to 2020 experienced accretion or new land forming for 629 Ha.Keywords: North coastal Java, accretion, Landsat, river estuary analysis, Cipunegara River, Cimanuk RiverKawasan pantai utara Jawa di Jawa Barat, khususnya daerah Cirebon, Indramayu, dan Subang, memiliki permasalahan hilang atau terbentuknya daratan baru melalui proses abrasi dan akresi. Pengamatan mengunakan citra dapat dijadikan tahapan awal untuk mengetahui sebaran abrasi dan akresi di sekitar wilayah pantai utara. Observasi perubahan daratan dilakukan dengan menggunakan citra landsat tahun 1978 dan 2020. Hasilnya memperlihatkan bahwa telah terjadi perubahan daratan, baik proses abrasi maupun akresi, di beberapa wilayah di sekitar muara-muara sungai besar seperti Sungai Cipunegara dan Sungai Cimanuk. Perubahan muara Sungai Cipunegara dan Sungai Cimanuk lebih disebabkan oleh tingginya pengendapan sedimen pada muara sungai tersebut dan membentuk lahan baru karena proses akresi. Pemantauan melalui citra satelit di Sungai Cipunagara data citra tahun 1978 sampai 2020 memperlihatkan penambahan lahan baru sebanyak 205 H. Analisis remote sensing citra di wilayah Sungai Cimanuk terlihat garis muara pantai pada tahun 1978 hingga tahun 2020 mengalami akresi atau penambahan lahan baru 629 H.Kata Kunci: Pantai utara Jawa, akresi, Landsat, analisis muara sungai, Sungai Cipunegara, Sungai Cimanuk
