Abstract

Optimizing cropping patterns under monsoon climates requires accurate information on soil water availability and its spatial variability. This study aimed to optimize cropping patterns and determine the optimal planting onset based on land-water balance analysis using the Thornthwaite-Mather water balance method and its spatial distribution in Rambipuji District, Jember Regency, Indonesia. Monthly land water balance was analyzed using the Thornthwaite–Mather method based on ten-year climatological data (2015–2024), including rainfall and reference evapotranspiration, and soil water holding capacity measurements across five land mapping units (LUMs) differentiated by slope, soil subgroup, and land use. Planting onset was determined using scientific criteria where soil moisture reached water holding capacity, and the effective rainfall to crop evapotranspiration was ≥ 0.75. The results showed a distinct monsoonal pattern, with water surpluses occurring from November to April and pronounced deficits from May to October. Soil texture significantly influenced water holding capacity, resulting in variations in the duration and intensity of water deficits among LUMs. Based on these conditions, LUM 1, 2, and 5 were recommended for planting in December, while LUM 3 and 4 were more suitable for January for the paddy crop. The optimal cropping pattern consisted of paddy cultivation in the first planting season followed by secondary crops in the second and third seasons, reflecting adaptive water-use strategies under declining rainfall. These findings demonstrate that integrating land-water balance analysis with spatial land characteristics provides a reliable basis for precision-oriented cropping calendar planning, supporting sustainable agricultural management.

Abstract

The Tiworo Watershed on Muna Island, Southeast Sulawesi, is experiencing significant ecological and anthropogenic pressures that threaten the sustainability of its ecosystem functions. Land cover changes have led to increased surface runoff and have impacted coastal ecosystems. This study aims to evaluate the carrying capacity of the Tiworo watershed by analyzing three key parameters: percentage of critical land  (PCL), percentage of vegetation cover  (PVC), and erosion index (EI), referring to the Minister of Forestry Regulation No. P.61/Menhut-II/2014. The research methods included spatial analysis based on Geographic Information Systems (GIS), collection of secondary data from satellite imagery and relevant agencies, and weighted calculations to determine land carrying capacity scores. The results revealed that 65.4% of the Tiworo watershed area is classified as potentially critical, with 8.14% falling into the critical to very critical category, mainly due to land use change and anthropogenic activities. Although vegetation cover is still relatively good (89.57%), the expansion of settlements and open land has the potential to disrupt ecological stability. The erosion index reached 13.65, far exceeding the tolerance threshold (ETOL 27.55 tons/ha/year), with 52.04% of the area experiencing very severe erosion (>480 tons/ha/year). The land carrying capacity score of 87.5 (good category) indicates that ecological capacity is still adequate, but high degradation pressure requires immediate intervention.

Abstract

This study aimed to evaluate land suitability for spatial-based agroforestry development by explicitly identifying the key biophysical characteristics of the Wanggu Watershed, an urban–peri-urban watershed experiencing rapid land-use change due to urban expansion and agricultural activities. The assessment focused on critical terrain and hydrological attributes, including slope class, elevation percentage, and distance from rivers, which strongly influence land productivity, erosion risk, and agroforestry feasibility. A Geographic Information System (GIS)-based spatial analysis was applied using a Multi-Criteria Evaluation (MCE) approach. Spatial datasets derived from Digital Elevation Models (DEM), river networks, and land characteristics were classified into weighted parameters: slope (0–15%, 15–35%, >35%) and river buffer distance (0–500 m, 500–1000 m, >1000 m). Each parameter was scored and overlaid to generate the land suitability maps. Field verification was conducted at 40 sampling points across six sub-districts to ensure consistency between spatial modeling and actual biophysical conditions.The results revealed distinct spatial patterns of land suitability driven by topographic variations. Lowland areas with gentle slopes (0–15%) are predominantly classified as suitable for productive agroforestry systems, whereas moderately sloping areas (15–35%) require conservation-oriented agroforestry practices. Steep terrains (>35%), mainly located in upstream regions, are more appropriate for protection and for ecological rehabilitation. In terms of hydrological proximity, areas located 500–1000 m from rivers showed the highest suitability, whereas riparian zones require careful ecological management. Overall, approximately 65–70% of the watershed is categorized as “Suitable,” and 30–35% as “Moderate.”These findings demonstrate that integrating biophysical characteristics through GIS-based MCE provides a robust basis for agroforestry zoning, thereby supporting sustainable land management and watershed conservation strategies.

Abstract

Managing coastal tourist areas requires an approach that can integrate ecological and socio-economic aspects so that environmental quality and community welfare are maintained. This study aims to analyze the ecological and socio-economic conditions in the Nambo Beach Tourism Area, Kendari City, and to formulate sustainable management strategies through an integrative ecology–social approach. The research was conducted in October–November 2025 through field surveys, water quality measurements (temperature, pH, salinity, DO, BOD, TSS, TDS), vegetation cover analysis based on the 2024 SHP, observations, as well as interviews and questionnaires with the community. The results show that most water quality parameters still meet marine tourism standards, although there is pressure on the TSS value (96 mg/L) and indications of increasing organic material shown by the BOD value (3.70 mg/L). Coastal vegetation cover, including mangroves, still dominates with an area of 5,910 hectares. but it’s starting to be pressured by increased tourism activities and development. On the socio-economic side, the community relies on income from tourism businesses, small trade, and transportation, but they face challenges such as low environmental awareness, limited public facilities, and suboptimal waste management. The integration of analyses using the ICM and SWOT approaches shows that Nambo Beach is in the aggressive strategy quadrant, meaning it has great potential for development.

Abstract

Rendahnya pemahaman anak usia sekolah dasar mengenai pengelolaan sampah menjadi salah satu masalah yang melatarbelakangi kegiatan ini, di mana sampah masih sering dibuang secara tercampur tanpa pemilahan antara sampah organik, anorganik, dan sampah yang dapat didaur ulang, sementara edukasi mengenai konsep 3R (Reduce, Reuse, Recycle) belum terintegrasi secara konsisten dalam kegiatan pembelajaran maupun budaya sekolah sehari-hari. Menjawab kondisi tersebut, SDN 100 Kendari menunjukkan komitmen kuat dalam pendidikan lingkungan hidup melalui edukasi pengelolaan sampah dengan konsep 3R, yang bertujuan untuk meningkatkan pemahaman siswa mengenai konsep 3R melalui penyuluhan interaktif, membentuk kebiasaan memilah sampah dan membuang sampah pada tempatnya secara konsisten di lingkungan sekolah, serta menghasilkan produk kerajinan tangan dari barang bekas seperti botol plastik, kaleng, dan koran sebagai wujud konkret penerapan prinsip reuse dan recycle. Kegiatan ini dilaksanakan melalui tiga tahap, yaitu sosialisasi interaktif mengenai konsep dan pentingnya 3R, praktik pemilahan sampah langsung oleh siswa menggunakan tempat sampah terpilah, serta workshop daur ulang yang membimbing siswa secara berkelompok mengubah barang bekas menjadi kerajinan tangan sederhana. Melalui rangkaian kegiatan edukasi 3R yang dilakukan secara interaktif tersebut, siswa tidak hanya memperoleh pemahaman mengenai pentingnya pengelolaan sampah dan menjaga kebersihan lingkungan, tetapi juga mulai membangun sikap peduli terhadap lingkungan melalui praktik sederhana yang dapat diterapkan dalam kehidupan sehari-hari.

Abstract

Watershed degradation in small islands is increasingly influenced by socio-economic pressures such as population growth, poverty, and weak governance. Therefore, this research aimed to assess the socio-economic carrying capacity of Tiworo Watershed on Muna Island. This research was conducted from March to June 2022 across Muna Regency and West Muna Regency. The analysis used three parameters in accordance with Ministerial Regulation No. P.61/Menhut-II/2014, namely population pressure, population welfare, as well as the existence and enforcement of rules. The researchers collected primary data through purposive sampling from local stakeholders and households, while secondary data originated from Badan Pusat Statistik (BPS) and local agencies. The results showed that the population pressure was 1.39 ha/household, indicating a moderate level. The population welfare level was categorized as poor (29.5% of households), with increasing dependence on forest resources and the potential for land conversion. Rule existence and enforcement were categorized as good because local communities still maintain local norms and practices, including spring protection and agroforestry. The overall socio-economic carrying capacity score was 105, placing the watershed in the moderate category. Strengthening welfare, land-use planning, and local wisdom-based management is necessary to support sustainable watershed governance.
