“…Perubahan penggunaan lahan di bagian hulu Daerah Aliran Sungai (DAS) sering kali dilakukan tanpa mempertimbangkan daya dukung lahannya (Valentin et al 2008). Faktor ekonomi menjadi alasan utama bagi penduduk untuk melakukannya sehingga mengakibatkan ketidakseimbangan lingkungan yang pada akhirnya menimbulkan degradasi lahan (Basuki et al 2016). Perubahan aktivitas tersebut akan berdampak pada masyarakat di bagian hilir DAS.…”

Land susceptibility to degradation is characterized by the loss of topsoil due to erosion which is considered as a threat to agricultural productivity. Information about land sensitivity to erosion is crucial in determining the appropriate soil and water conservation techniques to avoid land degradation. This study, which was located in the Gandul Sub-Watershed, aims to analyze the level of land sensitivity to erosion in highland agricultural areas. Data analysis was carried out spatially using land system and land-cover maps. Soil and water conservation efforts were determined based on the land function and sensitivity. The land sensitivity to erosion in the Gandul Sub-watershed was categorized into 3 levels which were moderate (3.9%), high (95%), and very high (0.8%). There were various directions for Gandul Sub-Watershed management by considering the level of sensitivity of the land and the function of the area. Creating a ridge is one of the soils and water conservation practices that has been implemented for a long time by local communities as a soil erosion prevention. Keywords: agriculture, erosion, Gandul, sensitivity

“…The precision of the terracing model toward the effects of terrestrial degradation can still be enlarged or influenced by factors such as land and crop ownership (Schönbrodt-Stitt et al, 2013), so the land conservation management practices should consider biophysical, social-economic and institutional aspects (Basuki et al, 2016). Land conservation techniques have shown to reduce topographic differences and sedimentary connectivity so shortly it will also reduce soil erosion and sediment delivery (Haiyan and Liying, 2017).…”

Banana is one type of fruits that is very potential to grow to support food security because it contains source of vitamins, minerals, and carbohydrates. Jenawi District has a dry land area that is potential for the development of banana plants. The purpose of this research was to plan the development of banana plants in accordance with the land conservation aspect against the threat of the erosion. The research was conducted by making land unit map, field survey, analysis of soil sample in the laboratory, and data analysis of erosion hazard level. Land unit mapping was made by overlay method so there were 12 units of land with the same land conditions. Field survey and sample analysis at the observation point was conducted to obtain the parameters: slope gradient, depth of solum, surface unity, slope length, bulk density, soil texture, soil C-organic, and soil permeability. The analysis of land conservation aspects for banana plants was determined from the level of erosion hazard with the USLE (Universal Soil Loss Equation) method. The results showed that the threat of moderate to severe erosion hazard for banana crops was overcome by the efforts of land conservation techniques using a good construction bench terrace. The threat of erosion hazard after land conservation directives is very low to low. The amount of the erosion prediction for banana plant planning in garden is 35.80 t/ha/yr (unit B unit), land use of dry fields is 29.82 t/ha/yr (land unit I), 31.54 t/ha/yr (land unit K), and 13.72 t/ha/yr (unit land L).

“…The change of matrix characteristics from landscape elements in areas could convert the watershed environmental behaviors, therefore, affecting the capture ability of the landscape to reduce degradation processes of watershed productivities (Bakker et al 2008;Guerra et al 2015). Landscape assessment based on depiction of land characteristics and quality provided description on its potential and susceptible to watershed deprivation (Basuki et al 2016). Furthermore, spatial distribution of land properties featuring watershed landscape was essential for various usages, for example for design watershed management.…”

Abstract. Barchia MF, Sulistyo B, Hindarto KS, Suhartoyo H. 2020. Assessment of Air Bengkulu (Indonesia) watershed based on agroecosystem landscape quality and sustainable land use plan. Biodiversitas 21: 5422-5430. This study purposes to assess agro-ecosystem landscape based on land quality values and current land use and assess agro-ecosystem matrices with agricultural conservation practices in Air Bengkulu Watershed conducted from August to December 2019. Spatial analysis used some map and Landsat 8 OLI satellite imagery and ArcGIS version 10.1. The analysis depicted spatial distribution of soil and land quality, land uses, agricultural landscape matrices, and sustainable agro-ecosystems. The assessments revealed soil quality covered Air Bengkulu Watershed categorized moderate 33.1% to good 14.4% suitable for sustainable agroecosystems while in marginal quality 38.9% mostly lying on the upstream. This unique landscape formed a land quality prone to degradation because of intensive agriculture for oil palm covering 60% and coffee plantation about 17%. Actually, only about 61.1% of the Air Bengkulu Watershed is categorized as moderate to good quality matrix of sustainable agroecosystems. Improper agricultural cultivation with monoculture system without implemented conservation practices drove landscape filled with degradation landscapes. With sustainable agro-ecosystem scenarios implementing physical conservation terraces and restored with multi-purposes tree species such as candlenut, kapok tree, betel nut, durian, good quality of the landscape matrix of 82% Air Bengkulu Watershed.
