Abstract

The Bayang Sani Watershed has an area of 1267.97 hectares with an average rainfall of 3117 mm/ year. The topography of this watershed have varies slopes. In the rainy season, the river water is a muddy color and both soil and rocks are contained in the river’s water that causes channel damage and reduced river capacity. It is caused by the wider distribution of land erosion in the Bayang Sani Watershed. The purpose of this study was to analyze the soil erodibility. The method of this study is a quantitative study and field survey method.  The data was collected by field survey and sample points were determined using purposive random sampling techniques. The sample was analyzed in the BPTP laboratory to determine the types and colors of the soil sample, depending on the quality of the soil's erosive value. The results show that soil erodibility in the Bayang Sani Watershed range 0.15-0.28. The low soil erodibility level found in land units F3.II.Kc.Qal.Lat (0.16), V2.II.Kc.Tomp.Lat (0.15) and V2.II.Sm.Tomp.Lat. (0.16) the moderate of soil erodibility was found in the land unit V3.III.Ht.Tomp.Lat (0.28).

Abstract

This research is motivated by the level of land erosion hazard that occurs with the characteristic category of moderate and bad land erosion levels, the total erosion hazard that occurs is 669.65 ha, so it has an impact on land cover changes in the Mount Padang area which resulted in Edp exceeding its 4.2 ton limit. . The purpose of this study is to formulate spatial-based erosion mitigation directions in the Mount Padang area to the level of land erosion that occurs. The type of research used is R&D (Research and Development) through the stages of studying and understanding previous research, field surveys, and finally conducting literature studies in formulating spatial-based mitigation directions for the level of land erosion hazards that occur. The findings were obtained by the authors formulate spatial-based erosion mitigation directions in the form of spatial-based map-making actions in the Mount Padang area, as well as providing socialization to local communities in the Mount Padang area to be able to manage their lands properly.

Abstract

This research is based on the Government’s lack of concern for the risk of Kaba Volcano eruption. Lack of preparedness of disasters, socialization for disaster mitigation, availability of the evacuation routes, or early warning systems in Kaba Volcano. On the other hand, with disaster preparedness, the damage and casualty figures can be minimized. The purpose of this study is to formulate the mitigation priority direction of Kaba Volcano eruption. Data collecting used interviews, observation and collecting relevant information. Then the data are grouped according to the danger levels criteria, the vulnerability, and the risks. Data processed by scoring and analyzing with AHP (Analytical Hierarchy Process). The results show that the direction of Bukit Kaba eruption mitigation priorities as follows: measured and periodic training and disaster simulation aspect is (0.832), coordination and collaboration in anticipating disasters is (0.813), human resources preparation is (0.801), evacuation route and site is (0.799), and the early warning system is (0.795).

Abstract

Tujuan penelitian adalah untuk mendeskripsikan kerusakan lahan yang dihasilkan dari aktivitas tsunami yang terjadi sepuluh tahun yang lalu. Kerusakan itu bisa dilihat dalam bentuk degradasi lahan hortikultura, ladang pertanian (tanaman dan horti), perkebunan. Data atau informasi yang diperoleh dari pengamatan langsung kelapangan dan disesuaikan, dianalisis data sekunder yang diperoleh dari instansi pemerintahan serta analisis studi literatur terkait permasalahan. Hasil analisis data primer dan sekunder serta studi literatur terhadap kerusakan lahan di Kabupaten Aceh Jaya diperoleh hasil bahwa lahan pertanian, kebun, dan vegetasi hutan masih dalam kondisi rusak berat dengan total luas lahanya jumlah kerusakan lahanya sampai 919,822 ha, sedangkan Lahan vegetasi hutan mangrove rusak sekitar 40,45 ha. Kerusakan lahan yang terjadi pada Kabupaten Aceh Jaya disebabkan oleh lamanya lahan digenangi air laut yang memiliki kadar garam yang tinggi serta adanya beberapa lahan masih di tutupi oleh endapan lumpur yang dibawah oleh tsunami.

Abstract

Penelitian ini mendiskripsikan tentang pencegahan tanah longsor di Kecamatan Simpang Empat Kabupaten Karo, konservasi lahan di Kecamatan Simpang Empat Kabupaten Karo. Penelitian yang akan dilakukan termasuk kategori penelitian deskriptif dengan metode yang digunakan adalah metode survei. sumber data adalah data primer yang dikumpulkan langsung di lapangan dan data sekunder adalah sumber referensi dan analisis yang diperoleh dari perpustakaan. Hasil penelitian menjelaskan bahwa: Pencegahan Longsor dapat dilakukan dengan (1) Jangan menebang atau merusak hutan, (2) Melakukan penanaman tanaman berakar, seperti Mimba, (3) Menanam tanaman bambu, akar wangi, leucaena, dll., pada lereng yang botak (4) Buat saluran air hujan, (5) Membangun dinding penahan di lereng curam (6) Periksa keadaan tanah secara berkala, (7) Mengukur tingkat kederasan hujan. Konservasi lahan adalah penggunaan lahan sesuai dengan kegunaan dan daya, setelah memanfaatkannnya kita harus menjaga dan mempertahankan produktivitas. Pada dasarnya upaya konservasi tanah harus dilakukan melalui, (a) mengurangi jumlah perusak energi, (b) menambah daya tahan tanah agregat untuk meniup dan menghujani air dan menggores lapisan permukaan, (c) meningkatkan perlindungan.

Abstract

This research was conducted in the Air Dingin watershed of West Sumatra which aim calculating changes of land cover area in Air Dingin watershed (2008 – 2021). To determine land cover changes using maximum likelihood classification by utilizing Arc Map 10.8. It can classify land cover change and Microsoft Excel software to calculate land cover change. The result shows that the landcover change of Air Dingin Watershed in 2008 - 2021 largest increase in the shrub area by 392.60 ha (3.1%) and followed by dry land agriculture which increased 215.18 ha (1.7 %), building area increased by 148.68 ha (1.2%), mixed gardens by 16.94 ha (0.1%). The increase in land area will be followed by a reduction in land cover, which has the largest decrease in forest area, namely 635.58 ha (5.0%), followed by a decrease in paddy fields of 129.25 ha (1.0%) , waters decreased by 8.57 ha (0.1%).

Abstract

This study examines the distribution of drinking water refilling business locations, to determine the distribution scheme of drinking water refilling businesses, and to determine the factors that influence the location of drinking water refilling business selection in Nanggalo District. This study used mixed methods research. For mapping the distribution of drinking water refilling businesses using geographic information systems (GIS), analysis of the distribution of drinking water refilling businesses using triangulation methods, analysis of nearest neighbors to determine patterns and distribution of businesses. Based on the results of the study, it can be concluded that there are 52 storage points in Nanggalo District spread across 6 districts. The distribution scheme, repeating the filling of water and beverages in Nanggalo sub-district, has a random pattern. Factors that influence the selection of the location of the drinking water refill business in Nanggalo District are accessibility, population density, production costs, according to recommended factors.
