Abstract

Sub-watersheds are formed from the interaction process of soil-forming factors such as geology, topography, and organisms. Each interaction process results in different characteristics of soil physical properties. Physical characteristics can serve as the main reference in planning, implementing, and evaluating appropriate management of Sub watershed Areas. The purpose of this study is to examine the characteristics of soil physical properties in the Manten Sub-watershed. This research uses an exploratory approach with a field survey approach through 3 stages of activities, namely pre-survey, survey, and post survey. Each land use was repeated five times to represent the area of each land use. The parameters observed include texture, bulk density, particle density, permeability, and porosity. The results show that the physical properties of the soil in the Catchment area of the Manten Sub-watershed, Malang Regency, are very different in each land unit. Soil texture is dominated by the loam class (T1, T4, T5, S1, S2, S3, K3, and K4). Based on the research results of soil physical properties in the catchment area of the Manten sub watershed, moorland use has better soil physical properties than dry field and paddy field land uses. The poor soil physical properties in dry field and paddy field land uses may be caused by excessive land cultivation and low soil organic matter content. Keywords: Catchment area, Land use unit, Soil physical, Sub-Watershed.

Abstract

Indonesia possesses vast land resources, offering significant potential for agricultural development. Among high-value commodities, durian (Durio zibethinus Murr.) is widely cultivated. Bumiaji District in Batu City, characterized by hilly topography and extensive agricultural land, serves as a prominent durian production center. Optimizing durian productivity, however, requires a thorough understanding of land suitability based on soil characteristics. This study evaluated land suitability for durian cultivation in Bumiaji District, focusing on key soil chemical properties, including soil pH, cation exchange capacity (CEC), base saturation (BS), and organic carbon (C-organic) content. The research was conducted using a survey method with purposive random sampling based on land mapping units (LMUs). Results indicated that most areas were classified as highly suitable (S1) based on CEC and organic carbon parameters, with CEC values ranging from 18.89 to 35.97 cmol/kg and C-organic levels above 1.2%. However, limitations were noted for pH and base saturation, with some areas classified as moderately (S2) or marginally suitable (S3). Improving land suitability can be achieved through targeted soil management strategies, such as liming with dolomite to enhance pH and base saturation. The findings of this study are expected to serve as a reference for implementing sustainable land management practices aimed at boosting durian productivity in Bumiaji District.

Abstract

Penelitian ini bertujuan untuk menganalisis sifat kimia tanah dan menentukan status kesuburan tanah pada kawasan Wisata Pacet Hill Kabupaten Mojokerto yang memiliki topografi berbukit dan rentan terhadap erosi serta pencucian hara. Analisis dilakukan terhadap pH, kapasitas tukar kation (KTK), kejenuhan basa, fosfor, kalium, dan karbon organik sebagai indikator utama produktivitas tanah. Hasil penelitian menunjukkan bahwa pH tanah berkisar masam hingga agak masam, KTK tergolong tinggi hingga sangat tinggi, dan kejenuhan basa bervariasi sangat luas dari sangat rendah hingga tinggi. Kandungan fosfor dan kalium menunjukkan distribusi yang tidak merata sesuai kondisi lereng dan vegetasi, sedangkan karbon organik relatif tinggi pada lokasi dengan tutupan vegetasi rapat. Berdasarkan metode matching, status kesuburan tanah di Pacet Hill berada pada kategori rendah hingga tinggi, dengan variasi yang dipengaruhi oleh ketinggian tempat, kemiringan lereng, serta akumulasi bahan organik. Elevasi rendah menunjukkan kesuburan lebih baik dibanding elevasi menengah dan tinggi yang mengalami pencucian basa lebih kuat. Hasil penelitian ini menegaskan perlunya pengelolaan berbasis konservasi melalui penambahan bahan organik, pengapuran, vegetasi penutup tanah, serta pengaturan aktivitas wisata untuk mempertahankan stabilitas kimia tanah dan keberlanjutan ekosistem kawasan wisata.

Abstract

The Bangsal Sub-watershed is located downstream of the greater Brantas Watershed. It is experiencing problems primarily with poor vegetation cover and high erosion rates. This study aimed to evaluate land capability classes based on land damage status across different land uses. Sampling was carried out purposively at 15 points across five land uses, namely, forests, plantations, dry fields, rice fields and shrublands. The parameters analyzed included the physical, chemical and biological properties of soil. Land capability assessment was conducted based on Arsyad’s work (2010), while damage status was based on the Government Regulation No. 150 of 2000 and the Ministry of Environment Regulation No. 07 of 2006. The results show that the Bangsal Sub-watershed is dominated by land capability classes III to IV with moderate damage status (R.II). Fourteen observation points show moderate damage, and one shows severe damage. The main limiting factors found include porosity, redox potential and permeability. Forest and shrubland land uses show the most stable conditions in terms of all three aforesaid limiting factors. Meanwhile, dry field land use has the most complex limiting factors, including slope, surface rockiness, bulk density, porosity and redox potential. These findings emphasize the importance of matching land use to land capacity to prevent further degradation. Management recommendations include increasing organic matter to improve soil structure, applying contour terraces on sloping terrain to reduce runoff and erosion and developing agroforestry systems to improve soil stability and support watershed sustainability.
