Abstract

The food crisis is an important issue faced by many countries, including Indonesia. Paddy field conversion caused decreasing rice production in many regions, one of which is in Toba Regency. Paddy field conversion should be controlled strategically to maintain the existence of the field for food production. This study aims: 1) to identify the conversion, availability, and rice needs 2) to identify the strengths, weaknesses, opportunities, and threats (SWOT factor) affecting paddy field conversion, 3) to generate strategies that control paddy field conversion. The SWOT factors were identified through descriptive methods, literature studies, and interviews. The strategies were constructed using a hybrid Analytical Hierarchy Process (AHP) and SWOT method. The results showed that rice availability decreased by -7,030 and demand increased by 4,001 tons between 2010 and 2020 due to paddy field conversion by 3,529 ha and increasing population. The main strength to be considered for controlling paddy field conversion is managing rice land, while the main weakness that might hinder the strategy is the low level of farmer education. Moreover, the main opportunity is supporting accessibility, and the main threat was regulation concerning sustainable agricultural land. The essential strategies to control paddy field conversion in Toba Regency include Land Protection Regulation, the subsidy of production input to farmers, and use of the local government budget to build agricultural infrastructure.

Abstract

An important aspect in describing the success of development is through analyzing the economic conditions of the region. Economic analysis also plays an important role in assessing regional inequality. Kabupaten Sumbawa Barat is one of the regions that has a diversity of resources and has various types of economic sectors. The objectives of this research include: (1) Analyzing the regional financial capacity in Kabupaten Sumbawa Barat; (2) Analyzing the Economic Base Sector by business field in Kabupaten Sumbawa Barat in 2019-2023; and (3) Analyzing the value of Economic inequality in Kabupaten Sumbawa Barat. The method applied in this research is quantitative descriptive method with secondary data from the Central Bureau of Statistics, and related agencies. The calculation techniques used are: Calculation of regional financial capability (Degree of Fiscal Decentralization); Financial Independence (Degree of Fiscal Autonomy); Location Quotient (LQ); and Williamson Index. The results showed that the value of the Degree of Fiscal Decentralization (DDF) in Kabupaten Sumbawa Barat in 2019 was 6% and fell into the category of very less, while for 2020 to 2023 it was 13% and fell into the category of less. Meanwhile, the value of the Degree of Fiscal Autonomy (DOF) in 2019 is the lowest value, namely 11.3 and has increased in 2023 to 22 and is included in the concurrency classification. The base sector is the mining and quarrying sector (4.78). The other three sectors that have the highest value and potential are the transportation and storage sector (0.31), the construction sector (0.29) and the agriculture, forestry and fisheries sector (0.29).While the sector with the lowest value is the processing industry (0.07). The value of economic inequality using the Wiliamson Index shows an inequality value of 0.77 and falls into the high inequality category.

Abstract

With Kupang City's subdistricts serving as the analysis unit, this study seeks to determine the hierarchy of service centers. The hierarchy level of service centers is ascertained by the use of centrality indices and scalogram techniques. The results are presented in a hierarchy table based on the presence and completeness of service facilities in each area. In Kupang City, Hierarchy I includes the Oebobo and Maulafa subdistricts, which have more complete facilities and infrastructure and function as primary service centers with significant influence on surrounding areas. Hierarchy II consists of the Alak and Kelapa Lima subdistricts, which, although having more facilities, are not as comprehensive as Oebobo and Maulafa, with lower service quality. Meanwhile, the Kota Raja and Kota Lama subdistricts are in Hierarchy III, with more limited facilities and functioning as local service centers with lower accessibility. The results of this study are expected to provide insights for the local government in planning related to service centers.

Abstract

Land productivity is significantly influenced by the patterns of land use and management practices employed. The excessive application of chemical composts and pesticides has been shown to degrade soil fertility and pose long-term threats to environmental sustainability. To mitigate these adverse effects, it is essential to introduce the principles of conservation-oriented agriculture from an early age. This community engagement activity was designed to provide elementary students at SD Negeri 13 Taliwang, West Sumbawa Regency, with direct experience in the production and application of organic compost. Moreover, the program aligns with the objectives of the Pancasila Student Profile Strengthening Project (P5), particularly through its focus on practical planting activities using potted plants. The implementation methods included an introductory session on the concept and environmental benefits of bokashi, which included a practical session involving direct student participation in the compost making process. Besides introducing eco-friendly technologies, the activity fostered environmental awareness among students. Similar programs should be continued to support early understanding of sustainable agriculture.

Abstract

Fast and accurate healthcare services, particularly in emergency situations, are highly influenced by the effectiveness of access to health facilities. Therefore, geographic accessibility becomes a key factor in improving both the accessibility and quality of services for the community. This study aims to map service coverage areas and determine the fastest routes to healthcare facilities in Denpasar City. The method employed is Network Analysis based on Geographic Information Systems (GIS), using QGIS 3.6 software. The analysis results indicate that there are 23 healthcare facilities evenly distributed across all subdistricts, all located within a 5 km radius of Sanglah Hospital. Distances to Sanglah Hospital range from 0.4 to 5 km, with estimated travel times between 0.48 and 6 minutes. The nearest facilities are RS Medika Prima II and RS Surya Husadha, located 0.4 km away with an estimated travel time of approximately 0.48 minutes, while RS Bhakti Rahayu is the farthest, at a distance of 5 km and a travel time of approximately 6 minutes. These findings provide important implications for evacuation route planning and the enhancement of spatially based emergency healthcare systems.

Abstract

Vegetation change is a key indicator for observing environmental dynamics using GIS and remote sensing approaches. Kupang City as an urban growth center in East Nusa Tenggara, is experiencing development pressures that affect the presence of natural vegetation. This study aims to map vegetation index changes and analyze their dynamics from 2014 to 2024. The method employed NDVI calculation using ArcGIS 10.8 software. The results show that high density vegetation increased from 2,124.9 ha in 2014 to 2,780.46 ha in 2024; medium-density vegetation decreased from 11,133.27 ha to 9,878.49 ha; low-density vegetation increased from 2,269.44 ha to 2,869.65 ha; and non-vegetation areas slightly decreased from 6.75 ha to 5.76 ha. The most significant change occurred in the medium-density class, with a conversion of 1,221.30 ha to low-density vegetation. These findings provide essential insights for vegetation monitoring and sustainable spatial planning in Kupang City.
