Abstract

Perubahan penggunaan lahan berupa tutupan lahan yang tidak terencana dapat menyebabkan kerusakan pada suatu Daerah Aliran Sungai, yang diindikasikan dengan adanya kondisi hidrologi yang menurun. Penelitian ini dilakukan untuk mengetahui pengaruh perubahan tutupan lahan terhadap respon hidrologi berupa nilai aliran permukaan, aliran lateral, air tanah dan debit aliran menggunakan Model Soil and Water Assessment Tool (SWAT). Kondisi tutupan lahan menggunakan citra satelit landsat pada tahun 2000, 2015 dan 2022. Klasifikasi tutupan lahan menghasilkan 8 kelas tutupan lahan menggunakan Google Earth Engine dengan tingkat akurasi Kappa Index tahun 2000, 2015, 2022 adalah 78.18%, 86.88%, 88.82%. Hasil tersebut memenuhi nilai kriteria kepuasan Kappa Index untuk digunakan dalam proses simulasi model SWAT. Terjadi peningkatan tutupan lahan Pemukiman, Lahan Terbuka dan Hutan pada tahun 2000-2022, yaitu sebesar 182.47 ha, 831.06 ha, dan 2469.85 ha. Simulasi Model SWAT dilakukan pada tahun 2015-2022, serta dilakukan kalibrasi dengan uji statistik koefisien determinasi (R2) dan Nash Sutchliffe Efficiency (NSE) dengan nilai 0.66 dan 0.58 yang menunjukan hasil memuaskan. Respon hidrologi di Sub Daerah Aliran Sungai Cimeta ditunjukan dengan terjadinya peningkatan nilai aliran permukaan dan penurunan aliran air tanah sebesar 686.44 dan 241.08 mm/tahun pada tahun 2000, 714.45 dan 227.9 mm/tahun pada tahun 2015, 731.66 dan 222.54 mm/tahun pada tahun 2022. Debit aliran di Sub Daerah Aliran Sungai Cimeta termasuk dalam kategori sedang yang artinya Sub Daerah Aliran Sungai Cimeta menunjukan pola aliran yang relatif konsisten dengan perubahan yang tidak terlalu berfluktiasi antara musim hujan dan musim kemarau.

Abstract

This research was conducted in Suntenjaya Village, Lembang, West Bandung Regency, focusing on lemon agro-industry development through the Analytical Hierarchy Process (AHP) method approach, area mapping, and water management to determine a sustainable factory location. The main objective is the selection of factory site by integrating lemon production considering sustainable agriculture aspects, product aspects, and water conservation programs. The results of the study provide a strong foundation for sustainable agro-industrial development will support sustainable agriculture, local economy, and environmental protection. The research also combined qualitative and quantitative elements with a mixed approach that included Focus Group Discussion (FGD) and AHP with the results showing that integrated drainage management was the top priority, followed by sanitation, clean water, reforestation, and sustainable agriculture. Mapping of areas based on geographical characteristics such as rainfall, slope, and soil type provided a map of water infiltration rates that became a key guide in planning water conservation programs. This research has positive implications in supporting sustainable agricultural practices and local economic empowerment. The results of the AHP analysis and area mapping form a strong framework for the development of a sustainable lemon agro-industry with positive economic and environmental impacts.

Abstract

Utilization up-land area for cultivating strategic food crops (paddy, corn and soybean) often neglects the rules of conservation so that it caused surface soil loss by run off. These events can reduce the fertility of agricultural land, so that it results in a decrease in land productivity and finally cause critical lands. Alternative conservation techniques that can be carried out through the application of hydro-mulch and geo-jute combination in order to reduce surface soil loss. The purpose of this study is to examine the use of hydro-mulch and geo-jute in reducing soil loss and observing maize growth as one of the effects of soil loss due to erosion. The treatments given are hydro-mulch, geo-jute and combination of hydro-mulch and geo-jute. The study showed that alternative conservation techniques in the form of hydro-mulch and geo-jute application proved to be able to reduce the amount of soil loss. The combination of hydro-mulch and geo-jute has the ability to reduce the amount of soil loss due to rainfall by 31.51%. Plot with geo-jute treatment can reduce soil loss by 21.86%, and plot with hydro-mulch treatment can reduce soil loss by 11.92%. The hydro-mulch and geo-jute combination can increase the growth of corn. Keywords:  Alternative, Erosion, Geo-jute, Hydro-mulch

Abstract

Talaga Bodas Nature Park is a volcanic ecotourism area vulnerable to degradation if not managed sustainably. This study aims to develop a sustainable development strategy based on a spatial eco-hydrological approach. This approach integrates NDVI (Normalized Difference Vegetation Index) satellite imagery analysis, erosion estimation using the RUSLE (Revised Universal Soil Loss Equation) method, and strategy formulation using the Analytical Hierarchy Process (AHP). The results show that most areas in Talaga Bodas have moderate to low NDVI values and erosion rates ranging from very light to very severe. The degradation of vegetation and high erosion potential is suspected to be related to uncontrolled tourism activity. AHP-based strategy priorities indicate that zoning regulation, local community involvement, and environmentally-based tourism development are the main strategies for sustainable development in Talaga Bodas. This study highlights the importance of an integrated eco-hydrological approach in managing ecologically vulnerable nature tourism areas.

Abstract

Cikeruh-Citarik sub-watershed is a part of the upstream zone of the Citarum watershed which is classified as a watershed with critical conditions in West Java. The change in land use as a side effect of the increasing population causes a degradation of the watershed. Land-use change in a watershed without considering any conservation rules leads to erosion, becoming a watershed criticality indicator. Erosion can be minimized by using a prediction model to predict the amount of erosion that might happen, for the result could help to decide which conservation action is needed in the watershed rehabilitation. GeoWEPP is one of the prediction models that is suitable for predicting the amount of erosion on a watershed scale. This research aims to study the preparation of the input data needed in the GeoWEPP model to predict the amount of erosion, especially in the Cikeruh-Citarik sub-watershed. The methodologies that were used in this research are literature study and field survey. According to the research results, the input data needed for GeoWEPP are DEM (Digital Elevation Model) data of the research area, climate database, soil type and soil physical properties database, land use and landcover data, and bridge files for soil, land cover data, and evapotranspiration calculation.

Abstract

Sub DAS Cisangkuy memiliki bentuk lahan berupa perbukitan hingga pegunungan, didominasi oleh kemiringan lereng agak curam dan curam. Karakteristik wilayah tersebut menyebabkan Sub DAS Cisangkuy termasuk daerah yang rawan terjadi bencana longsor. Penelitian ini bertujuan untuk mengetahui karakteristik wilayah melalui parameter kerawanan longsor dan memetakan sebaran tingkat kerawanan longsor di Sub DAS Cisangkuy memanfaatkan Sistem Informasi Geografis (SIG). Penelitian ini menggunakan metode analisis spasial berupa tumpang susun atau overlay, skoring dan pembobotan. Model yang digunakan merujuk pada pendugaan Puslittanak tahun 2004 dengan parameter berupa curah hujan, kemiringan lereng, jenis tanah, jenis batuan penyusun (geologi), dan penggunaan lahan. Hasil penelitian menunjukkan bahwa Sub DAS Cisangkuy didominasi oleh macam tanah andosol eutrik, jenis batuan vulkanik, kemiringan lereng 16-25%, penggunaan lahan hutan, dan intensitas curah hujan rata-rata tahunan 2001-2500 mm/tahun. Terdapat 3 tingkat kerawanan longsor di Sub DAS Cisangkuy diantaranya tingkat kerawanan rendah seluas 1293,91 ha (4,54%), kerawanan sedang seluas 6698,59 ha (23,48%), dan kerawanan tinggi seluas 20537,5 ha (71,99%).
