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

Declining soil fertility can be a major factor affecting soil productivity. Declining soil fertility can be caused by two factors, namely natural factors such as topography, and man made factors, such as land management. Assessment of soil fertility status is very important understand good soil fertility conditions that support agricultural and plantation activities. This study aims to determine the soil fertility status and the classification of soil fertility capability. This research was conducted through field survey on four land use units (LUUs) with 16 sampling points determined purposively. The obtained data were then combined to classify the level of status and ability of soil fertility using Fertility Capability Classification (FCC) method. The results showed that the overall LUUs have low fertility status criteria with base saturation (BS) as a heavy limiting factor, and potassium (K) and C-organic content as medium limiting factors. All LUUs, however, revealed almost the same FCC unit. Based on the FCC unit, soil fertility is constrained by some sandy texture soil types (S), with modifiers of acid soil reaction conditions (h), steep slopes (%), and some are constrained by low potassium (k).

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

Market demand for cardamom (Elettaria cardamomum) continues to rise, yet its cultivation remains limited to specific regions with suitable environmental conditions. Therefore, land suitability evaluation is essential as a basis for planning the development of this commodity. This study aims to assess land suitability for cardamom cultivation in Sumber Rejo Village, Purwosari Subdistrict, Pasuruan Regency. The evaluation was based on physical and chemical soil properties, including pH, organic carbon (C-organic), cation exchange capacity (CEC), base saturation, as well as soil texture and slope. Samples were collected from two types of land use: dry land (tegalan) and coffee plantations, with a total of six sampling points. The results showed that soil pH ranged from 5.70 to 5.92 (S1), C-organic ranged from 1.61% to 2.79% (S1), CEC from 23.93 to 33.07 cmol/kg (S1), and base saturation was in average < 35% (S2). Overall, the study area falls into the moderately suitable (S2) category for cardamom cultivation with potential improvement to S1 through manure and compost application. This evaluation, however, was based on only four parameters so that future research should continue with other parameters to have a more comprehensive results on land suitability for cardamom cultivation in Sumber Rejo village.

Abstract

Panglungan Village located in Wonosalam District, Jombang, with an altitude of less than 500 m above sea level, an area of 6.89 km2, and a population of 3,381 people. Most of the people's livelihoods rely on forest products such as coffee, durian, and avocado and a small portion come from dry land. The Panglungan Village community is part of the Forest Farmers Group (KTH) “U.D. Abadi Berkah Porang”, started to build porang nurseries, still on a household scale. The purpose of developing nurseries is to create alternative sources of livelihood that can be developed in the Panglungan Village area and its surroundings. Partner problems are 1). Farmers find it difficult to get porang seeds 2). Farmers' skills in Porang nurseries are still lacking 3). Quality porang seeds are not yet available, 4). The role of KTH “U.D. Abadi Berkah Porang” is not yet optimal. The solution to the problem is 1) Producing porang seedlings, 2). Assisting porang nurseries 3). Assistance with porang seed certification, 4). Empowering KTH "Abadi Berkah Porang" to play a role in helping to increase the economic capacity of the community through porang nurseries. The conclusion of community service activities is using seeds from porang seeds, 50 thousand porang seeds planted, assistance in making demonstration plots for purification of the Madiun-1 variety covering an area of 500 m2, the potential for porang nurseries to increase economic capacity is quite promising. Recommendations for future seed development are required to increase the number of seeds to meet other areas.

Abstract

Sumber Rejo Village, Purwosari District, Pasuruan Regency is one of the coffee-producing areas in East Java, generating a substantial amount of coffee husk waste during each harvesting season. This waste has not been optimally utilized and is commonly discarded around processing areas, potentially causing environmental pollution. At the same time, farmers still rely heavily on inorganic fertilizers, resulting in increased production costs. This community service program aimed to improve the knowledge and practical skills of members of the Sinar Agro Permata Farmer Group in processing coffee husk waste into compost and liquid organic fertilizer (LOF) with economic value. The program employed a Participatory Action Research approach through coordination, socialization, technical training, demonstration plots, mentoring, monitoring, and evaluation. The activities involved 55 farmer group members. Demonstration plots successfully produced 100 kg of compost and 50 liters of liquid organic fertilizer as learning media and field application materials. Evaluation results indicated that prior to the training, approximately 90% of participants had no knowledge of compost and liquid organic fertilizer production. After completing the program, 85% of participants were able to independently produce both products according to the recommended procedures. The program successfully enhanced community capacity in utilizing coffee husk waste into environmentally friendly products with potential economic benefits while supporting sustainable agriculture and circular economy practices.
