Watershed is a medium system where hydrological-biophysical processes as part of hydrological cycle and social, economic, and cultural events as the results of human intervention on natural resource occur. The increasing human population results in the increasing need of water that may reduce the availability of water, causing environmental degradation. The objectives of this study were to study the characteristics of Tabunio watershed and to give recommendation on the enrichment planting for the watershed recovery. This study used watershed ecological area approach and the data were analyzed spatially using GIS. The results showed that based on the characteristics of its components, Tabunio Watershed was categorized as moderately to very highly qualified for recovery. The recovery should be done through: (i) enrichment planting based on the land capability, land suitability and the legal function of the area, (ii) conservation of soil and water using vegetative and civil engineering methods, and (iii) issuance of regulations to increase the watershed's carrying capacity.
Tutupan lahan dapat mempengaruhi sifat fisik tanah yang berhubungan dengan laju, kapasitas dan volume infiltrasi pada suatu lahan. Tujuan dari penelitian ini ialah untuk mengetahuilajuinfiltrasisertamenganalisisbesarvolumedankapasitasinfiltrasi padabebagaitutupanlahan untuk merumuskan dan mengevaluasi kerentanan lingkungan di DAS Tabunio dan DAS Maluka. Kegiatan penelitian dilaksanakan di Sub DAS Amparo Kecil DAS Tabunio dan Sub DAS Bati-Bati DAS Maluka Provinsi Kalimantan Selatan.Peralatan utama yang digunakan dalam metode penelitian ini adalah double ring infiltrometer, GPS (Global Positioning System), aplikasi GIS (Geographic Information System) untuk mengetahui kapasitas dan volume infiltrasi masing masing unit lahan. Sub DAS Amparo Kecil DAS Tabunio terlihat bahwa kerentanan lingkungan yaitu: a) Kapasitas infiltrasi tertinggi terdapat pada lahan hutan sekunder muda yaitu 334,92 mm/jam dan volume infiltrasi tertinggi terdapat pada tutupan lahan hutan sekunder tua yaitu 307,37 mm3, sedangkan kapasitas dan volume infiltrasi terendah terdapat pada tutupan lahan semak belukar yaitu 49,12 mm/jam dan 27,85 mm3. b) Kerentanan lingkungan pada tutupan lahan semak belukar dengan laju infiltrasi 28,33 mm/jam, kapasitas 49,12 mm/jam dan volume infiltrasi 27,85 mm3Tutupan lahan dapat mempengaruhi sifat fisik tanah yang berhubungan dengan laju, kapasitas dan volume infiltrasi pada suatu lahan.

Watershed Tabunio is one of the watershed in the Province of South Kalimantan which has an important role to support the environmental aspects and socio-economic aspects, it is caused by the upstream part of the watershed there are different types of land use can increase the rate of erosion, the flow surface, also on the middle and downstream utilized by the Tanah Laut for agriculture, plantation and fisheries. This study aims to determine the level of erosion, which is useful as a reference for determining the direction of land use for the carrying capacity of watershed restoration efforts Tabunio. This research method using a regional approach ecological watershed analysis process and presentation done spatially through Geographic Information Systems. The results showed that: a) Amount highest erosion 219,08 ton/ha/yr on Land Unit 3B (mining land use with a gradient of 3-8%), while the lowest amount of erosion 11,44 ton/ha/yr on Land Unit 8 (use secondary dry forest with gradients of 25-40%); b) The level of erosion is very light Danger land unit 8 on the use of secondary dry forest on the slope of 25-40%), while other land units at the rate of moderate to severe erosion. Recovery of the carrying capacity of the watershed Tabunio lower the rate of erosion through soil and water conservation vegetatively and civil engineering (mechanical).
Land cover is anything that includes any types of appearance on the surface of the earth on a particular land. Information related to land cover can be used as at the parameter to determine the amount of runoff in a catchment area. This study was conducted in the Catchment Area (CA) of Mangkauk using Landsat 8 OLI/TIRS 2014 scene path/row 117/62 with the methods of Support Vector Machine (SVM) and Artificial Neural Network (ANN). The classification of land cover in Mangkauk catchment area included forests, plantations, shrubs, reeds/grasses, rice fields, open lands, settlements and water body. Based on the accuracy test of land cover classification using SVM, the value of the overall accuracy was 97.22% with Kappa Coefficient 0.96, while using ANN 86.33% with Kappa Coefficient 0.79.
The Sub-DAS Riam Kiwa is a tributary of the Martapura upstream, which is often used by the community to cover daily needs such as cooking, washing, and latrines. The current quality of water condition of the Sub-DAS Riam Kiwa is estimated to have decreased caused by various human activities on the riverbank. This study aims to determine the strategy of controlling river water pollution. The river as a research area is set at 24.4 km. Water quality was measured and observed at 3 sampling points then analyzed using the Pollution Index method. Analysis of water pollution control strategies was using SWOT Analysis. The results showed that the Sub-DAS Riam Kiwa was classified as moderately polluted with an IP value from upstream to downstream of 7.88; 8.92; and 9.38. To maintain water quality in natural conditions a water pollution control strategy is needed through diversification of existing strategies or programs as a result of 1) strong internal factors including the monitoring of water quality, water quality standards; and 2) the many threats from external factors which include the disposal of domestic waste and livestock without recycling, the community does not have the knowledge of waste and the community often violates government regulations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
