Analisis Kebutuhan Lahan Berdasarkan Distribusi Sebaran Penduduk di Kabupaten Mamuju

Radinal Jayadi — 2026-05-28

An analysis of land requirements based on population distribution in Mamuju Regency is essential for evaluating sectoral policies that influence spatial utilization and agrarian resource management. This study aims to provide an evaluative foundation for the revision process of the 2025 Regional Spatial Plan (RTRW) of Mamuju Regency, ensuring that the future direction of spatial structure and land‐use patterns can be formulated more comprehensively and responsively to existing conditions. The analytical methods employed include assessing land availability for cultivation activities and mapping population distribution across zones categorized as available and unavailable for such utilization. The findings indicate that land availability for cultivation activities in Mamuju Regency covers 1,215 km², while 3,736 km² are classified as unavailable, including designated protected areas. Of the total population, 259,539 residents occupy areas where land is available for utilization, whereas 29,520 residents live in areas categorized as unavailable, most of which fall within protected zones as defined by the RTRW. These results underscore the need to evaluate policies related to protected area designation and enhance the inventory of land tenure within forest areas that serve as objects of agrarian reform, including the redistribution of land to local communities. Accordingly, the utilization of agrarian resources in Mamuju Regency is expected to proceed more effectively, efficiently, and sustainably, while maintaining a balance between development needs and environmental conservation.

Adhitya Ferdiansyah Murdiyanto — 2026-05-28

The Free Nutritious Meals (MBG) is one of the Indonesian government's programs in realizing Indonesia's golden age by 2045. The results of the study state that the effectiveness of the MBG program is highly dependent on targeted operational governance, considering the still high level of inequality in Indonesia, especially in eastern Indonesia. The purpose of this study is to measure the effectiveness of the SPPG Location in serving educational facilities in Ambon City. In line with that, according to the Decree of the Head of the National Nutrition Agency number 401.1 of 2025 concerning technical guidelines for the Governance of the Implementation of the Free Nutritious Meal Program in 2026, 1 SPPG point has a maximum radius of 6 km or a maximum travel time of 30 minutes. From this basis, the researcher analyzed using the isochrone analysis approach of travel distance, isochrone travel time and time-matrix distance. All data were taken from Google POI taken from Google Maps scraping. The results of the time-matrix distance analysis showed that 67% of educational facilities were in Class 3 (low accessibility) with a travel time of >30 minutes. These findings imply the need to evaluate SPPG placement policies, not only based on air radius but also taking into account road network and topographic analysis. The study's primary recommendation is the implementation of a Hub-and-Spoke strategy by adding sub-distribution points and utilizing motorcycles (refrigerated box motorcycles) to reach geographically challenging areas, such as South Leitimur District, to ensure the nutritional quality of food is maintained until it reaches students.

Tingkat Pengetahuan Masyarakat dalam Kesiapsiagaan Bencana di Indonesia

Ajeng Purwati Ningtyas — 2026-05-28

Indonesia is among the countries with the highest natural disaster risk due to its location at the convergence of three tectonic plates and within the Pacific Ring of Fire. Although Indonesia has established regulatory and institutional frameworks for disaster management, limited public understanding of disaster risks remains a major barrier to effective preparedness. This study examines the level of community disaster-risk knowledge and its influence on disaster preparedness. A quantitative survey was conducted involving 155 respondents selected through accidental sampling. Data were collected through an online five-point Likert-scale questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS. The findings reveal that community knowledge has a positive and significant effect on disaster preparedness (β = 0.712; t = 12.068; p < 0.001), explaining 50.7% of the variance in preparedness (R² = 0.507). The average knowledge score was moderate (mean = 3.56), with a declining trend across higher cognitive dimensions, from knowing to analysis. The lowest preparedness indicator was ownership of a Disaster Readiness Bag/Tas Siaga Bencana (mean = 2.95), indicating limited public adoption of BNPB recommendations. These results highlight the need for disaster education programs that not only provide factual information but also strengthen individuals’ capacity to apply and analyze disaster risks. The study supports the Sendai Framework for Disaster Risk Reduction 2015–2030, particularly its first priority of understanding disaster risk as the foundation of preparedness.

Kebijakan Pengelolaan Pasar Rakyat dan Fungsi Sosial-Ekonomi Kawasan Perkotaan di Sengkang, Kabupaten Wajo

Sitti Rabiatul Wahdaniyah Herman — 2026-05-28

This study aims to examine the relationship between public market management policy and the socio-economic function of the urban area in Sengkang, Wajo Regency. The study employs a qualitative approach through a policy study based on the examination of legal instruments, regional planning documents, government administration reports, and official statistical data related to market management and urban dynamics. The findings show that the public market management policy in Wajo Regency has positioned the market as an important node of trade activities and public services within the urban structure of Sengkang. The policy also encompasses the dimensions of protection, empowerment, guidance, and market revitalization. However, at the implementation level, the linkage between market policy and the strengthening of the area’s socio-economic function has not yet operated optimally. The main constraints lie in the still limited integration with spatial planning, the management of supporting facilities, and the measurement of market service performance. This study underscores the need to strengthen the synchronization between public market policy and urban area planning so that the market functions not only as a space for transactions, but also as a driver of local economic growth and urban social services.

Wa Ode Sitti Jurianti Aswad — 2026-05-28

This study aims to analyze the priority for improving the quality of the Namlea District square area as a public open space based on visitors’ perceptions. This research employed a quantitative descriptive approach. Data were collected through observation, documentation, and questionnaires distributed to visitors of the square area. The data were analyzed using Importance Performance Analysis (IPA) to compare the performance level and importance level of 15 public open space attributes. The results show that the conformity level between performance and importance reached 83.23%, with an average performance score of 3.34 and an average importance score of 4.01. The IPA Cartesian diagram identified six attributes as the main improvement priorities: facility completeness, facility condition, availability of sports areas, cleanliness facilities, architectural aesthetic elements, and spaces for informal sector activities. The study concludes that the Namlea District square has strong potential as a public open space due to its strategic location and multifunctional role. However, its quality still needs to be improved, particularly in facilities and area management, to create a more comfortable, active, inclusive, and sustainable public space.

Analisis Klaster Bentuk Lahan Dengan Pendekatan Indeks Moran dan Local Indicators of Spatial Association (LISA) di Kabupaten Gorontalo

Sri Rahmawati Habie — 2026-05-28

Landforms reflect interactions among geological, hydrological, and human processes, influencing a region’s capacity to support socio economic activities. This study analyzes spatial patterns of landforms in Gorontalo Regency and their relationship with population density using Moran’s I and Local Indicators of Spatial Association (LISA). Data include landform maps, administrative boundaries, and 2024 population density. Analyses were conducted globally (Moran’s I), locally (LISA), using the median approach, and Bivariate Moran’s I. Results indicate that landform distribution is relatively random with weak spatial autocorrelation, whereas population density shows contrasting patterns across neighboring areas. Median and bivariate analyses reveal hidden spatial structures and outliers (Low-High, High-Low), reflecting local mismatches between physical terrain and demographic pressure. These findings highlight the importance of adaptive micro-spatial planning and the consideration of additional variables for sustainable regional development.

Analisis Spasial Zona Potensi Penangkapan Ikan (ZPPI) Menggunakan Parameter SST dan Klorofil-a di Wilayah Pesisir Bali Utara

Putri Indraswari — 2026-05-28

This study aims to analyze the potential of Fishing Ground Zones (ZPPI) in the coastal waters of North Bali using Sea Surface Temperature (SST) and chlorophyll-a concentration parameter. A descriptive quantitative and spatial approach was applied, utilizing Level 3 Aqua MODIS satellite imagery collected from January 2021 to January 2025. The analysis identified three zonation categories: potential zones (271.65 km²), less potential zones dominating most of the study area, and non-potential zones (50.1 km²). Although SST and chlorophyll-a are theoretically positively correlated with fishery productivity, linear regression tests revealed a very weak relationship, with the highest R-squared value of only 0.092 in 2024, suggesting that other oceanographic factors — such as Indonesian Throughflow dynamics and terrestrial nutrient runoff — play a more dominant role in driving chlorophyll-a variability in this region. Spatial distribution of potential zones is concentrated in strategic coastal areas near small island clusters and entirely within the 12-nautical-mile boundary, making them accessible for small-scale fishers. This study contributes a remote-sensing-based spatial dataset of ZPPI that can serve as a reference for sustainable coastal resource management planning in North Bali.

A Spatio-Temporal Evaluation of Water Resilience and Urban Metabolism in Informal Settlements using Remote Sensing

Ramdan Pano Anwar — 2026-05-28

Informal settlements face layered challenges of environmental degradation, governance fragmentation, and infrastructure inequity. This study aims to evaluate the spatial-temporal dynamics of environmental and hydrological stress within these settlements to inform targeted upgrading strategies. Utilizing Google Earth Engine and QGIS, multi-temporal and multi-spectral satellite imagery from Landsat 8/9 and Sentinel-2 (2015–2024) was processed to map ecological stress and urban expansion in Makassar, Indonesia. The methodological approach includes the calculation and zonal statistics extraction of key indices: Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI), Land Surface Temperature (LST), and Moisture Stress Index (MSI). The findings reveal a severe ecological gradient characterized by a continuous downward trend in vegetation (NDVI < 0.2) and a corresponding escalation of surface impermeability in informal zones. This urban densification directly driven thermal intensification, with LST peaking above 34°C, and extreme moisture stress exceeding critical resilience thresholds (MSI > 0.9). Ultimately, this integrated geospatial diagnostic empowers the SLAIS Framework to transition landscape architecture into an operable, evidence-based discipline capable of targeting interventions where metabolic pathology is greatest.

Arahan Penutupan Lahan Daerah Aliran Sungai Batu-batu sebagai Upaya Mitigasi Pendangkalan Danau Tempe

Chaeria Anila — 2026-05-28

The Lake Tempe ecosystem is one of Indonesia’s national priority lakes that requires restoration due to severe sedimentation. The lake plays an important role in supporting regional economic resilience, social sustainability, and community livelihoods. The natural shallowing of the lake is caused by sediment transported by rivers flowing into the lake, including the Batu-Batu River. Previous oceanographic and limnological studies identified the highest accumulation of Total Suspended Solids (TSS) at the Batu-Batu River estuary. This study aims to analyze sediment conditions and formulate appropriate land-use directions as a sedimentation mitigation strategy in the Batu-Batu Watershed. Sediment accumulation was simulated using the Soil and Water Assessment Tool (SWAT) hydrological model. Land-use recommendations were developed by considering areas with heavy and very heavy sedimentation classes, land capability classes, 2020 land cover conditions, and the 2032 Spatial Pattern Plan. The simulation results show that sediment production in 2020 reached 1,233,509.04 tons/year, indicating a high sedimentation rate. Under the 2032 spatial planning scenario, sediment yield is projected to increase by 30.10% compared to existing conditions. However, the proposed land-use directions could reduce sediment yield by 66.17%. These findings indicate that the proposed land-use strategy can be considered in future regional spatial planning and watershed management policies.
