Abstract

The increasing demand for drinking water due to population growth presents significant challenges for the Among Tirto Water Utility (ATWU) in Batu City, East Java, Indonesia. In 2022, ATWU faced low service coverage (36%) and high water loss (38%), exceeding the 20% threshold. Some previous research discusses the System Dynamics (SD) used to overcome the water shortage problem. In this study, the SD is used to overcome excess water. Therefore, This study aims to enhance efficiency by adding piping networks and controlling water losses. This research uses an SD approach method that includes simulations from 2017 to 2042 or for 25 years using the Powersim application. Methodologies include analyzing drinking water availability, constructing causal loop diagrams (CLD) and stock and flow diagrams (SFD), verification, validation, and designing policy scenarios. The required data are the number of customers, service coverage, actual production capacity, water loss, total community water consumption, business revenue, business expenses, and other data related to water management in ATWU. The study identifies Scenario Two as the most effective in addressing location-specific issues. If water loss control is implemented to reduce loss rates to 20%, ATWU could expand service coverage by 58.44%, increasing water availability and a projected profit of 3.6 billion rupiahs by 2042. The results of this study can improve operational efficiency and facilitate better decision-making for the Water Utility of Batu City.

Abstract

Abstract The Jatiroto River Basin is on the border of Lumajang Regency and Jember Regency. The Jatiroto watershed experienced an increase in runoff due to high rainfall intensity, relatively steep land slope conditions, and changes in land use. This problem has the potential to cause disasters, namely floods, landslides, and cold lava floods. The research uses the ArcSWAT (Soil and Water Assessment Tool) to determine the amount of erosion and sedimentation that occurs in the Jatiroto Subwatershed, then maps the distribution of the Erosion Hazard Index so that it can determine conservation directions in accordance with watershed conditions. Based on the results of ArcSWAT 2012 modeling, the amount of erosion was 47,470 tons/ha/year, or 3,955 mm/year, and the existing sedimentation was 29,279 tons/ha/year. The IBE distribution is low criteria at 0%, medium at 39.033%, and high at 60.966%. Conservation efforts based on Land Rehabilitation and Conservation Directions (ARLKT) found that the area's function was 50.89% cultivation, 5.62% protection, and 43.48% buffer. The erosion rate after vegetative conservation efforts were carried out was 29,279 tons/ha/year, or 2,439 mm/year, and sedimentation was 12,701 tons/ha/year. The distribution of IBE after conservation is low (0%), medium (100%), and high (0%). Thus, after vegetative conservation directives, the value of erosion and sedimentation has decreased and has met the permissible requirements. Keywords: Jatiroto Sub Watershed, ArcSWAT, Erosion Hazard Index, Conservation Abstrak Daerah Aliran Sungai Jatiroto berada di perbatasan Kabupaten Lumajang dan Kabupaten Jember. DAS Jatiroto mengalami peningkatan debit limpasan karena intensitas hujan yang tinggi, kondisi kemiringan lahan yang relatif curam, dan perubahan tata guna lahan. Adanya permasalahan ini berpotensi mengakibatkan bencana yaitu banjir, tanah longsor dan banjir lahar dingin. Penelitian menggunakan metode ArcSWAT (Soil and Water Assesment Tool) yang bertujuan untuk mengetahui besarnya nilai erosi dan sedimentasi yang terjadi pada Sub DAS Jatiroto, kemudian memetakan sebaran Indeks Bahaya Erosi sehingga dapat menentukan arahan konservasi yang sesuai dengan kondisi DAS. Dengan demikian, nilai erosi dan sedimentasi dapat diketahui dan dapat memeberikan rekomendasi arahan penggunaan lahan yang sesuai dengan kondisi DAS serta dapat mengurangi nilai erosi dan sedimentasi. Berdasarkan hasil pemodelan ArcSWAT diperoleh besar erosi 47,470 ton/ha/tahun atau sebesar 3,955 mm/tahun dan sedimentasi eksisting 29,279 ton/ha/tahun. Sebaran IBE yaitu kriteria rendah sebesar 0 %, sedang sebesar 39,033%, tinggi sebesar 60,966%. Upaya konservasi berdasarkan Arahan Rehabilitasi dan Konservasi Tanah (ARLKT) didapatkan fungsi kawasan yaitu budidaya 50,89%, lindung 5,62% dan penyangga 43,48%. Nilai laju erosi setelah dilakukan upaya konservasi berupa arahan secara vegetatif menjadi 29,279 ton/ha/tahun atau 2,439 mm/tahun dan sedimentasi sebesar 12,701 ton/ha/tahun. Persebaran IBE setelah konservasi yaitu pada tingkat rendah 0%, sedang 100% dan tinggi 0%. Dengan demikian setelah dilakukan arahan konservasi secara vegetatif nilai erosi dan sedimentasi mengalami penuruan dan sudah memenuhi persyaratan yang diizinkan.

Abstract

The downstream Wanggu watershed is located in Kendari City, the capital of Southeast Sulawesi Province, with an area of 329.59 km2. So it is very important to arrange the right space. In this research, an analysis of the impact of changes in land cover on sedimentation levels will be carried out, as a basis for considering space utilization so as not to exceed the carrying capacity of the watershed. The analysis method uses the Arcswat application, and land cover changes using comparative data for 2001, 2006, 2009, 2014, and 2020. One of the obstacles in land cover classification is the presence of clouds that cover part of the image. In this research, Google Earth Engine (GEE) is used which will automatically process historical data so that areas covered by clouds are replaced with images that are clear of clouds. The research results show that agricultural land cover has the greatest influence, and overall the watershed shows accumulated sedimentation of 2,515,409.90 tons or a rate of 76.40 tons/ha for land cover in 2001 and sedimentation of 2,808,683.45 tons or rate 85.31 tons/ha. for land cover in 2020.

Abstract

Bencana banjir merupakan suatu ancaman pada DAS Rejoso yang dapat menghambat kegiatan masyarakat dan dapat menimbulkan kerugian. Untuk menanggulangi banjir yang terjadi setiap tahun, diperlukan pengelompokan daerah rawan banjir dengan memanfaatkan Sistem Informasi Geografis (SIG) menggunakan metode scoring dan pembobotan. Terdapat 6 parameter banjir yang digunakan, yaitu curah hujan, kemiringan lereng, elevasi, kerapatan sungai, jenis tanah, dan tutupan lahan. Dari hasil pemetaan diperoleh 5 kelas rawan banjir yang berbeda yaitu “sangat rawan” dengan luas 44,58 km2 (12,01%), “rawan” dengan luas 85,77 km2 (23.10%), “sedang” dengan luas 40,31 km2 (10,86%), “tidak rawan” dengan luas 92,03 km2 (24,78%), dan “sangat tidak rawan” dengan luas 108,63 km2 (29,26%). Kemudian dilakukan analisis upaya mitigasi struktural dengan embung kecil dan kolam retensi serta mitigasi non-struktural dengan sistem peringatan dini.

Abstract

Banjir merupakan salah satu bencana alam yang paling sering terjadi di Indonesia. Bencana banjir menjadi ancaman bagi Daerah Aliran Sungai (DAS) Welang setiap tahunnya. Topografi yang relatif datar dan perubahan kondisi Daerah Aliran Sungai (DAS) menyebabkan sedimentasi di wilayah hilir mengakibatkan berkurangnya kapasitas sungai. Sehingga saat musim penghujan, sungai akan meluap dan mengakibatkan banjir. Tujuan dari penelitian ini untuk mengetahui peta kerawanan banjir DAS Welang sebagai dasar penentuan upaya mitigasi. Analisis peta kerawanan banjir menggunakan metode overlay dan skoring melalui software ArcGIS 10.4.1 dengan 6 parameter kerawanan banjir, yakni curah hujan kala ulang 25 tahun, penggunaan lahan, kemiringan lereng, jenis tanah, kerapatan sungai, dan ketinggian lahan atau elevasi. Berdasarkan hasil analisis diperoleh sebaran daerah rawan banjir dengan kelas sangat rendah 110,84 km2 (22,31%), rendah 91,09 km2 (18,33%), sedang 106,48 km2 (21,43%), tinggi 157,98 km2 (31,80%), dan sangat tinggi 30,44 km2 (6,13%). Dari hasil peta kerawanan banjir, dipilih arahan upaya mitigasi struktural berupa 5 titik embung kecil dan 4 titik kolam retensi, serta mitigasi non struktural berupa penentuan titik dan rekomendasi alat peringatan dini dan penetapan tingkat status banjir berdasarkan SNI 8840-3:2022.

Abstract

Perubahan tata guna lahan yang terjadi pada DAS Welang menyebabkan kawasan tersebut sering mengalami bencana banjir akibat meningkatnya erosi dan sedimentasi. Pada studi ini menggunakan model ArcSWAT untuk menghitung potensi erosi dan sedimentasi yang terjadi sehingga dapat memetakan sebaran Indeks Bahaya Erosi (IBE) pada DAS Welang sehingga dapat dilakukan usaha konservasi yang optimal. Berdasarkan hasil simulasi pada kondisi eksisting didapatkan rata-rata laju erosi eksisting sebesar 31,947 ton/ha/tahun dan sedimentasi 27,569 ton/ha/tahun. Hasil yang didapatkan dari analisis Indeks Bahaya Erosi (IBE) yaitu IBE sedang dengan luas 29.602,068 ha (61,3 % dari luas total), kriteria tinggi dengan luas 18.691,649 ha (38,7 % dari luas total). Dengan menggunakan upaya konservasi vegetatif dengan mengganti penggunaan lahan pertanian lahan kering, semak belukar, dan tanah terbuka menjadi hutan berpedoman pada RLKT. Memperoleh nilai Indeks Bahaya Erosi (IBE) rendah dengan luas 5.162,207 ha (10,69 % dari luas total) dan IBE sedang dengan luas 43.131,510 ha (10,69 % dari luas total). Hasil tersebut menunjukkan pelaksanaan usaha konservasi vegetatif dapat mengurangi erosi maupun sedimen pada DAS Welang.

Abstract

The Ministry of Forestry has designated the Way Rarem sub-watershed, part of Tulang Bawang, a critical watershed, as a priority. Several reasons cause land criticality, including deforestation and inappropriate land use, which cause erosion and sedimentation. In this case, the criticality of the watershed occurs due to the high erosion rate, which impacts flooding in the Way Rarem subwatershed area. Over the past year, there have been flood disasters at five points in the Tulang Bawang watershed. Based on information from BNPB (National Disaster Management Agency), the flood disaster affected 140 families. The losses that occur due to flooding that arise due to erosion and sedimentation need to be studied in more depth; therefore, the situation in the Way Rarem Sub-watershed is important to study further. The objectives of this study are to determine the Erosion Hazard Index, measure the erosion rate in the Way Rarem sub-watershed using the USLE method, and provide adequate conservation strategies. The required data are rainfall data, soil type, slope, and land use in 2019 and 2023 as a comparison. GIS was used to process all the data. The results showed that the erosion rate in 2019 was 21933.9 tons/ha/year, whereas in 2023, it was 14187.4 tons/ha/year, with the Erosion Hazard Index dominated by the 'Very High' category. For conservation direction, three alternative conservation activities are carried out, namely by vegetative, mechanical, and vegetative-mechanical methods. Based on the results of the analysis, the appropriate conservation direction to reduce the erosion rate is vegetative-mechanical conservation, which can reduce the erosion rate by 66.9% of the existing erosion rate. From the results obtained, it is hoped that new concepts in land conservation that have not yet been implemented in the Way Rarem Sub-watershed can be taken into consideration. Combining two conservation methods, vegetative and mechanical, can be an alternative to controlling erosion that occurs in the Way Rarem Sub-watershed.

Abstract

Way Sekampung subwatershed is the watershed area of Way Sekampung dam. The changes in land use that occurred in the Way Sekampung subwatershed caused flooding and landslides. To reduce existing problems, vegetative and mechanical land conservation efforts are needed. In this study, the USLE method was used to estimate the rate of erosion and then map the distribution of the Erosion Hazard Index in the Way Sekampung Subwatershed with the help of Geographic Information System (GIS). Based on existing conditions, the erosion rate in 2017 was 29626.262 tons/ha/year; in 2022, the erosion rate was 76617.579 tons/ha/year. The results of the analysis of the Erosion Hazard Index in 2017 and 2022 showed four criteria, namely low with a difference of -1.115%, moderate with an increase of 1.140%, high with a difference of -0.097%, and very high with a difference of 0.071%. Conservation with new land use, construction of terraces, and check dams has resulted in a reduction in erosion in the Way Sekampung Subwatershed with an Erosion Hazard Index, which is a low index increase of 26.992% from the existing condition and a very high 22.819% reduction from the existing condition. These results show that land conservation can reduce erosion in the Way Sekampung Subwatershed.

Abstract

Human activities such as urbanization, population growth, agricultural expansion, deforestation, and industrialization significantly influence changes in land cover and the environment. The United Nations World Urbanization Prospects reports that by 2030, around 60% of the world’s population will live in cities, increasing from 54% in 2014 to 66% in 2050. This change in land cover can cause environmental disasters such as erosion and flooding, resulting in biodiversity loss, land degradation, and pollution. Therefore, monitoring land cover changes is a priority for researchers and policymakers. This research analyses land cover changes from 2012, 2017, and 2022, predicting 2027 and 2032. Landsat satellite image processing to create land cover maps for 2012, 2017, and 2022 uses a supervised classification method in GIS software and predicts land cover for 2027 and 2032. It was carried out with the help of TerrSet software with a CA-Markov model using spatial data on land cover maps for 2012, 2017, and 2022. The results of this process show that land cover of lakes, forests, plantations, and rice fields decreased in each period, while land cover of dry land, residential areas, bushes, and ponds experienced an increase. The result validation value in 2012 was 81.98%, in 2017, 76.83%, and in 2022, 79.57%, and validation in 2022 on Terrset of 0.7190.
