Abstract

South Solok Regency with a population of more than 163,000 people, 62.3% without access to clean water services through the Domestic Water Company (PDAM). The number of PDAM customers has been changed in Solok Selatan Regency in the last five years. Since the water capacity is very limited which means it difficult to increase the number of customers, so it is predicted to be unable to meet the increasing need for clean water. Based on the study of the potential for raw water availability in the South Solok Regency, Sungai Kapur has the potential as a source of raw water. To complete the potential study, it is necessary to know the quantity of raw water by examining hydrological parameters to optimize the planning of water resources potential. The quantity of raw water is assessed by the dependable flow to determine the low flow characteristic. Based on calculations, obtained a reliable discharge of 90% in monthly that can be used as raw water. The raw water source used has a discharge of ± 138.6 l / sec. However, the availability is uneven throughout the month, so a reservoir is needed to guarantee the availability of raw water for residents. In addition, raw water quality is assessed in terms of physical, chemical, and biological aspects. The results of the raw water quality test in the Sungai Kapur are eligible for raw water based on Government Regulations No. 82, 2001

Abstract

Peluang jumlah curah hujan ekstrim tidak mudah untuk diperkirakan, karena setiap wilayah mempunyai spesifik distribusi probabilitas kejadian hujan. Pada studi ini, penulis mengevaluasi distribusi probabilitas normal, log normal, gumbel dan log-pearson III pada daerah aliran sungai Kuranji. Data curah hujan harian pada tiga stasiun penakar yaitu stasiun Batu Busuk, stasiun Bendung Koto Tuo dan stasiun Gunung Nago selama 17 tahun digunakan dalam perhitungan. Pada pengujian keselarasan uji chi-kuadrat dan Smirnov-Kolmogorov didapatkan distribusi probabilitas log-Pearson III dapat diterima untuk wilayah daerah aliran sungai Kuranji, Padang.

Abstract

Penelitian ini bertujuan untuk menggambarkan peta sub-DAS Kuranji dengan menganalisa data DEMNAS pada perangkat Arc GIS, mendeskripsikan karakteristik curah hujan dan debit puncak dengan metode Rational pada setiap sub DAS. Hasil penelitian adalah pada DAS Kuranji terdapat 10 (sepuluh) sub DAS Kuranji, yaitu sub DAS Batang Padang Karuah, Batang Padang Janiah Hulu, Batang Padang Janiah, Batang Limau Manis, Batang Kuranji, Batang Sapih, Batang Aie Lareh, Batang Malvinas, Ulak Karang Utara dan Air Tawar. Sub DAS Padang Karuah merupakan sub DAS terluas pada DAS Kuranji, yaitu 47.88 km2, sedangkan sub DAS Malvinas merupakan sub DAS terkecil, yatitu 3.91 km2. Berdasarkan peta hasil penelitian, sungai Batang Balimbing, Batang Lurus dan Batang Maransi melewati Sub BAS Batang Aie Lareh dan memberikan kontribusi debit ekstrem pada kawasan DAS Kuranji tersebut.

Abstract

Forum DAS Kota Padang menemukan adanya kerusakan di lima DAS di Kota Padang. Salah satu kerusakan ada pada DAS Batang Kuranji yang berisi aliran sungai Batang Guo. Sungai Batang Guo merupakan anak sungai Batang Kuranji yang airnya dimanfaatkan sebagai air baku, pembangkit listrik mikro hidro, dan irigasi. Kerusakan disebabkan oleh kerusakan hutan di bagian hulu sehingga mempercepat kerusakan DAS di bagian hilir. Berdasarkan temuan tersebut perlunya edukasi kepada masyarakat tentang konservasi air dengan melestarikan sumber daya air sungai berupa kegiatan menjaga kondisi tebing sungai. Hal ini dilakukan dengan memberdayakan masyarakat sekitar wilayah sungai dalam bentuk penanaman bambu di sepanjang tebing Batang Guo. Beberapa kegiatan yang dilakukan sebelum penanaman adalah kegiatan penyuluhan dan kegiatan pembibitan dan penanaman. Rangkaian kegiatan pemberdayaan yang dilakukan kepada masyarakat wilayah hulu sungai Batang Guo telah menambah pengetahuan penduduk dalam hal budidaya bambu, konservasi air, dan peluang bisnis terhadap keberadaan bambu tersebut. The Padang City River Basin Forum (RB) found damage to five RBs in Padang City. One of the damages was on the Batang Kuranji RB, which contains the Batang Guo River. The Batang Guo River is a tributary of the Batang Kuranji River, whose water is used as raw water, micro-hydro power plants, and irrigation. The damage is caused by damage to the forest in the upstream area, thus accelerating the damage to the RB downstream. Based on these findings, educating the public about water conservation is necessary by conserving river water resources to maintain riverbank conditions. Conservation efforts are carried out by empowering communities around the river by planting bamboo along the Batang Guo cliffs. Some activities carried out before planting were extension and nursery and planting activities. The series of empowerment activities carried out for the people of the upper reaches of the Batang Guo River have increased the knowledge of the residents in terms of bamboo cultivation, water conservation, and business opportunities regarding the existence of this bamboo.

Abstract

Digital elevation models (DEMs) are essential to accurately predict river cross-section in the watershed. Technological developments of unmanned aerial vehicles (UAVs) or drone has received a lot of attention in various research field to get the latest information from the area, because of its mobility, high resolution, and low cost, so it can be a competitive alternative to produce maps with precise georeferences. However, this has not been tested so far. In this study, We evaluated the accuracy of the DEMs generated from UAV imagery by comparing it to DEMNAS, DEM SRTM, and direct topographic measurements. We performed regression analysis on the river bed elevation of the Kuranji River Padang, where the river bed elevation is the result of the analysis of each DEM. The result found that for river bed elevation of the DEM Drone performed competitively to DEMNAS with the correlation test value (r) were 0,992 and 0.954, respectively. The result of the DEM SRTM analysis has a wider range of data variations than the DEM Drone and DEMNAS.
