Abstract

Deforestation in the Serayu watershed, Central Java province, Indonesia for agriculture and other uses leaves only 0.73% of vegetation. It has triggered a number of problems such as soil loss (erosion), landslides, floods and sedimentation downstream. Environmental damage control needs to be applied through appropriate conservation programs. This study aims to understand the distribution of soil erosion and the effectiveness of soil erosion control by using vegetation cover. Soil erosion modeling and its correlation to vegetation cover was performed by using an Arc GIS based model of the Revised Universal Soil Loss Equation (RUSLE) through five scenarios of vegetation landscape cover such as 10%, 15%, 20%, 25%, and 30% of the total area of the study site. Five parameters namely rain erosivity (R), soil erodibility (K), slope-length (LS) and crop management (C) and conservation practices (P) factor were used to calculate soil erosion. The results indicated 82.25 tons/ha/year soil erosion reduction due to enhancement of vegetation cover from the actual condition 0.73% to the 30% vegetation cover condition. The increase of 5% vegetation landscape cover (forest) detracted the soil erosion rate by 10,20 tons /ha/year. Very high and high soil erosion hazard levels were found in the northern, east, and west watershed areasKeywords:   Soil erosion, RUSLE model, GIS, Serayu watershed, Vegetation cover

Abstract

Soil erosion is an environmental problem in the tropics that can cause the loss of topsoil. If it continues, it will result in a decrease in soil fertility and land productivity. So, it is necessary to quickly predict the erosion hazard level using the USLE method based on GIS. This research aims to analyze the distribution of erosion hazard levels in the Durensewu Sub-watershed, Gadjah Mungkur Reservoir Wonogiri, based on GIS. The research was conducted in the Durensewu Sub-watershed, Wonogiri, in January-April 2024. Data processed include rainfall (R), erodibility (K), slope (LS), and land cover and management (CP). The R-value in the Durensewu Subwatershed is 169.24-204.216. Soil groups of Ustropepts and Dystrudepts showed K values of 0.39 and 0.46, respectively. The topography of the Durensewu Subwatershed is gently sloping to very steep. Mixed gardens, settlements, and rice fields dominate land use. The erosion hazard level in the Durensewu Subwatershed is evenly distributed in the mild, moderate, and severe hazard classes.

Abstract

Kawasan Kopirejo, yang terletak di Desa Bambang, Kecamatan Wajak, Kabupaten Malang, merupakan daerah pasca erupsi Gunung Semeru yang sedang dikembangkan sebagai desa wisata dengan komoditas utama kopi dan durian. Wilayah ini memiliki karakteristik tanah dominan berpasir dan topografi yang bervariasi, dengan risiko erosi yang cukup tinggi. Dalam upaya mendukung pengelolaan lahan secara berkelanjutan, teknologi drone digunakan sebagai alat monitoring kondisi fisiografi lahan secara real-time.Pengabdian masyarakat ini dilakukan melalui pendekatan pemetaan partisipatif, yang mengintegrasikan data hasil observasi lapangan dengan pemetaan drone beresolusi tinggi. Hasil pemetaan menunjukkan bahwa kondisi biofisik lahan mempengaruhi produktivitas tanaman kopi dan durian, serta perlunya strategi konservasi yang sesuai. Pemanfaatan drone terbukti efektif dalam memberikan informasi spasial mengenai kemiringan lereng, tutupan lahan, serta perubahan kondisi tanah pasca erosi.Implementasi teknologi drone diharapkan dapat meningkatkan pengelolaan kebun kopi rakyat, memperkuat upaya revegetasi, serta mengoptimalkan pengembangan desa wisata Kopirejo secara sosial-ekonomi dan agroekosistem. Integrasi antara akademisi, masyarakat, dan pemerintah menjadi kunci keberlanjutan program ini.

Abstract

Soil is a fundamental factor influencing agricultural productivity, as it determines nutrient availability, water retention, and the long-term sustainability of farming systems. The Bareng Wonosalam District of Jombang Regency is a significant agricultural area with varied topography and intensive land use; however, comprehensive soil characterization in this region remains limited. This study aimed to analyze the physical and chemical characteristics of soils in plantation lands and classify them taxonomically to inform sustainable management. A representative plantation site in Pulosari Dua was selected using land-use and slope overlays. Five soil horizons (Ap, AB, Bt1, Bt2, BC) were described. Samples were analyzed for moisture content, texture, bulk density, pH (H₂O, KCl), electrical conductivity, organic carbon, total nitrogen, available phosphorus (Olsen, Bray), exchangeable cations (K, Na, Ca, Mg), cation exchange capacity (CEC), and base saturation (BS). Results showed moisture content of 6.2–20.8%, bulk density of 1.23–1.52 g/cm³, pH of 5.35–5.99, and organic carbon of 0.77–3.61%. Exchangeable K and Na were low (<0.60 cmol·kg⁻¹), while Ca ranged from 3.69–7.06 cmol·kg⁻¹. Textures were silty clay and clay, with BS of 53.5–117.1% and CEC of 9.15–12.93 cmol·kg⁻¹. The soils were classified as Typic Hapludalfs. Recommended practices include dolomite liming, potassium fertilization, structural amendments, and terracing. These actions are expected to enhance soil fertility, water retention, and plantation productivity by enabling targeted soil amendments, balanced nutrient application, and erosion control measures that directly address the identified limitations.

Abstract

Soil erosion in upland watersheds reduces land productivity, degrades water quality, and threatens ecological services, particularly in areas undergoing tourism‑driven land‑use change. This study quantified and mapped soil erosion in the Brangkal Sub-Watershed, with a focus on the Pacet Hills tourism area in Mojokerto, East Java. The study employed the Universal Soil Loss Equation (USLE) in combination with ArcGIS, incorporating rainfall erosivity (R), soil erodibility (K), slope length–steepness (LS), land cover (C), and conservation practice (P). Rainfall erosivity was derived from five‑year precipitation records using the Lenvain method, soil erodibility from laboratory‑analyzed texture and organic matter, LS from a 30 m DEM, and CP from land‑use classification adjusted with field observations. All factors were rasterized and multiplied cell‑by‑cell in ArcGIS to generate annual soil loss estimates and hazard maps. Results indicated annual soil loss between 7.24 and 1922.75 ton ha⁻¹ yr⁻¹, with severe erosion concentrated in steep, intensively cultivated upper‑catchment zones where LS and CP values are high. Field‑derived and reference K values were in close agreement, validating the reliability of hotspot identification. Soils, dominated by Andisols and Inceptisols, exhibited moderate to high erodibility, especially under reduced vegetation cover. Recommended management priorities are vegetative reinforcement, structural slope stabilization, nutrient and pH correction, and land‑use zoning to minimize disturbances in high‑risk areas. The integration of USLE and GIS provides a robust framework for prioritizing conservation actions that protect soil resources while sustaining the ecological and tourism value of Pacet Hills.
