Abstract

The food production in South Kalimantan Province is mostly gained from tidal irrigation along the downstream of Barito river. Tabunganen unit an area of 5600 ha, is one of the area under Tabunganen subdistrict. Previously the rice production in Tabunganen unit was considered sufficient, with the production rate of 2,5-3,0 ton/ha. Currently some areas near the tidal ponds have very low productivity, around 1-1,5 ton/ha. Some farmers presume that the decline in productivity is caused by soil acidity. This research is aimed to investigate the influence of water quality on soil quality in Tabunganen unit. Some measurements are taken in secondary and tertiary channels (upstream, middle, downstream), the value of Fe (mg/l), DHL (mmhos) and pH. The flow and water quality measurements are taken every 3 hours within 26 hours. Water level is measured for 15 days. The result of this research shows that pH values in both secondary and tertiary (upstream, middle, downstream) are pH>6. During rise and fall tide, the pH values of the right and left ponds are still same. This condition indicated the disfunction of the ponds retaining soil acidity, especially some areas near the tidal ponds. Therefore, the field has high potency for pirit oxidation. In tertiary channel, the DHL values is DHL>3290 mmhos, pH value is 6<pH<7 and Fe value is 0,01-1 mg/l.Keywords:Water quality, tidal irrigation, Barito river Permalink: http://ejournal.undip.ac.id/index.php/keairan/article/view/2716[How to cite: Bhakty, T.E.

Abstract

The principle of the unit hydrograph (HS) method is the direct runoff hydrograph due to effective rainfall, which remains at 1 mm/hour and is uniform across the entire catchment or river basin area, thus requiring verification for the use of the HS method and examining the relationship between catchment area and correction factor. This research uses the HSS Gama 1. The parameters investigated for HSS Gamma 1 are parameters in four catchment areas in Yogyakarta, namely DAS Progo, Sub-DAS Winongo, Sub-DAS Code, and Sub-DAS Ngrancah. The results of this study indicate that the larger the catchment area, the smaller the thickness of rainfall on HSS Gama 1. If the thickness of rainfall is less than 1 mm/hour, then hydrograph the HSS Gama 1 of correction below hydrograph the HSS Gama 1 of initial. There is a correlation between the catchment area and the correction factor, meaning that the larger the catchment area, the greater the correction factor in the HSS Gama 1 method with the logarithmic regression method and a correlation coefficient of 0.9958.

Abstract

Topografi wilayah Desa Benteng Raja, Kecamatan Borong, Kabupaten Manggarai Timur, Provinsi NTT yang berbukit-bukit menyebabkan air sulit mengalir karena elevasi sumber air lebih rendah dibandingkan permukiman penduduk. Hal ini membuat masyarakat kesulitan mendapatkan air bersih, di mana masyarakat harus berjalan ratusan meter untuk mencapai sumber air. Oleh karena itu, diperlukan upaya untuk merancang SPAM yang sederhana dan ekonomis agar air dari mata air Wae Menang dan Wae Belang dapat didistribusikan ke wilayah Desa Benteng Raja. Tim pengabdi sebagai tim utama bertanggung jawab atas desain pompa hidram, pipa hantar, serta uji coba untuk menentukan kapasitas pompa hidram untuk diterapkan pada SPAM. Selain itu, tim pengabdi juga melakukan pengamatan di lokasi, instalasi pompa, serta uji performa pompa. Seluruh kegiatan ini dilakukan dengan dukungan swadaya dari masyarakat Desa Benteng Raja. Debit Wae Menang diperoleh 1,42 l/s dan Wae Belang diperoleh 1,23 l/s (total 2,65 l/s). Performa desain pompa hidram I menghasilkan debit 0,65 l/s dan jangkauan pipa hantar hanya 100 m, hidram II diperoleh debit 1,15 l/s dan jangkauan 500 m, hidram III diperoleh debit 1,44 l/s, pipa pemasukan 30 m, dan jangkauan pipa hantar mencapai 1,5 km. Dengan demikian maka pompa hidram III sudah optimal untuk diaplikasiskan pada SPAM.

Abstract

Irrigation is very important in supporting sustainability food in the Dadapan area, Sleman Regency, but is hampered by budget limitations. Asset Management Planning (PMA) is needed to determine appropriate irrigation management budget priorities, according to regional characteristics. It is also important to know the influence of the five pillars of irrigation on Asset Management Planning. This research uses data on irrigation conditions and budget allocations for 2019-2022, maps of irrigation areas, maps of irrigation networks, both analog and digital, digital maps combined with related thematic maps on image maps or Google Earth with the Geographic Information System (GIS). Tabular data on network conditions was inventoried from 116 DI. Descriptive analysis method for regional characteristics and asset conditions, multiple regression for asset value using the Cost Replacement New (CRN) and Depreciated Replacement Cost (DRC) method and Partial Least Square analysis to determine the relationship between irrigation pillars with PMA. The results of the inventory of irrigation performance achievements in 2022 are 82%, but the irrigation network is good at less than 40%. Most were in a condition of light damage (58%) and some were moderately damaged (20%). PMA is appropriate in the Dadapan area by considering the priority scale according to the condition of asset damage and regional characteristics, interpreted using GIS, taking into account risk factors. The results of the 2023 CRN calculation are approximately 219% of the 2003 calculation. The most dominant variable influencing PMA is management with = 0.699 p = 0.000, then the condition of infrastructure with = 0.131 p = 0.031. The other variables are not significant. The R-square value is 471, which means that the variable that can be explained by the dependent variable PMA is 47.10% of the other constructs.
