Abstract

Women are the most marginalized and vulnerable to disasters due to disadvantaged socio-economic status and unequal access to resources in Bangladesh. Common perceptions paint women as dependent, weak, incapable, and subordinate, viewing them as burdens, which keeps them isolated from the mainstream processes of society, like planning and decision-making. The present study was conducted in the Kurigram and Patuakhali districts of Bangladesh. It aimed to explore women's role in disaster management, focusing on the nature of their involvement and different social factors that influence women's participation. Primary data were collected through 203 questionnaires from two districts, and 4 FGDs were conducted to validate and cross-check the data obtained from the questionnaires. 2 Expert opinion surveys have been conducted in the study area. The data reveals the present condition of women's participation in disaster management processes and their undervalued contribution in different stages, different factors influencing their active participation, the evolution and future perspectives about their involvement in disaster management. Participants reported that a lack of educational awareness programs and work independence hinder their active participation in disaster management.  Findings highlight a significant gap regarding the current gender responsive disaster management policies. The result highlights that it is necessary to ensure their contributions are recognized at all levels of disaster management.

Abstract

Surakarta City, as one of the strategic service centers in Central Java Province, is facing challenges in realizing equal distribution of educational facilities by the Indonesian National Standard (SNI). This study aims to evaluate existing conditions, gaps in needs, and the level of conformity between the provision of educational facilities and applicable standards. The approaches used include quantitative descriptive methods, spatial analysis, buffering techniques, Average Nearest Neighbor Analysis (ANN), Kernel Density Estimation (KDE), and descriptive qualitative analysis. The findings show a striking inequality in the distribution of educational facilities between regions, with a higher concentration of facilities in the city center compared to the outskirts. Through ANN and KDE analysis, it was found that the distribution pattern of educational facilities varies, from clustered, random, to scattered patterns, depending on the level of education. The shortage of facilities was recorded at the elementary school level of 140 units, junior high schools 49 units, and senior high schools/vocational schools 41 units. Based on these results, it is recommended that a strategy be developed to distribute educational facilities more evenly, considering spatial needs and demographic dynamics. This finding is an important foundation in planning sustainable education based on a spatial approach in Surakarta City.

Abstract

Sragen Regency is one of the regencies experiencing regional development by facing challenges in infrastructure distribution. One of the manifestations of these challenges is the presence of slum areas, namely the Ngrampal slum. This study aims to determine the existing conditions and factors that influence the existence of Ngrampal slums in the perspective of sustainable settlements, using quantitative methods through a deductive approach. This research uses quantitative methods, with data collection techniques through observation, questionnaires, and institutional surveys. The data analysis technique used was Exploratory Factor Analysis (EFA). This research has resulted in new factor groups regarding the factors that influence the existence of slums in Ngrampal slums: 1) infrastructure factors and cultural preservation efforts and 2) spatial factors and environmental-social conditions of the community. With these results, attention to the maintenance, availability, and affordability of basic settlement infrastructure is one of the important steps to improve community welfare. In addition, development is also important to improve the environmental and social quality of the community.

Abstract

Bandung Regency has considerable potential for ginger production. However, weak supply chain management was linked to the limited involvement of farmers in the value chain. This study aimed to analyze the ginger supply chain in Bandung Regency using a descriptive method. The supply chain structure was evaluated using the FSCN framework, while the spatial flow of ginger was mapped using ArcMap. The performance of the supply chain was measured by calculating marketing margins and farmers' share. The results indicated that the ginger supply chain operated through three main channels, with collectors playing a dominant role. Spatial analysis revealed integration between marketing channels and distribution volumes. The smallest marketing margins were found in channel 3, with Rp—2,500 for Ginger Elephant Chinese and Rp 3,500 for Ginger Paris/Emprit. Similarly, the highest farmer's share was also observed in channel 3, with 85.29% for ginger elephant China and 79.41% for ginger paris/emprit. This highlighted that channel 3 provided the most favourable returns for farmers.

Abstract

The transition to renewable energy requires competent human resources (HR) to achieve national energy security. This study examines Indonesia's HR readiness for the energy transition through an integrated perspective on energy security and the defense science philosophy. This systematic literature review analyzed 15 high-quality sources (from 30 initially identified, 2020-2025) to examine human resources readiness for Indonesia's energy transition. Using a PRISMA-aligned methodology, 13 key studies (11 journal articles and two institutional reports) were selected for detailed analysis, with two additional sources supporting the development of the thematic framework. The analysis integrates perspectives on energy security, defense science, and defense anthropology to identify HR readiness challenges, with particular emphasis on regional disparities. Despite Indonesia's renewable energy target of 17%-19% for 2025 (revised from an initial target of 23%), current realization remains at only 13.1% (2024), revealing critical competency gaps in the human resources sector. Key findings include: Indonesia ranks sixth globally for energy-sector emissions (691.97 million tons of CO2 in 2022); significant geographic disparities exist, with Java having 204 educational institutions for energy training, compared to only 3 in remote provinces. Required competencies encompass multidisciplinary technical skills, adaptability to technology, and security-aware soft skills. Policy recommendations include energy security-based training programs, competency certification standards, the establishment of an HR energy security council, and the integration of defense anthropology principles into HR development. This research provides a strategic understanding of HR readiness requirements essential for supporting Indonesia's equitable energy transition toward sustainable national energy security.

Abstract

Global efforts to reduce reliance on fossil fuels and greenhouse gas emissions increasingly emphasize the potential of marine energy as a renewable resource. This study analyzes the characteristics of significant wave height and estimates of wave energy and wave power in the northern waters of Central Java, Indonesia, during 2024. ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF) were processed using Python to generate monthly maps of wave height and wave energy, daily time series of energy and power, and boxplots of monthly wave-energy distribution. The annual significant wave height ranged from 0.1 to 1.6 m, with the highest values occurring in December and March and the lowest in April and November. Monthly wave energy exceeded 1,200 J m⁻², while daily wave-energy density reached up to 3,000 J m⁻² and daily wave power peaked near 6 kW m⁻¹ during the west monsoon season. The highest variability occurred in March and December, reflecting the influence of monsoonal wind forcing. These findings demonstrate that the northern Central Java Sea has promising, relatively stable wave-energy potential, particularly during the west monsoon. They may contribute to Indonesia’s clean-energy transition, coastal resilience, and small-island electrification, in alignment with Sustainable Development Goals 7 and 13.

Abstract

Plastic waste pollution increasingly threatens the ecological and hydrological functions of the Ciliwung River Basin, yet identifying its sources remains difficult due to interacting physical and socio-economic factors. This study aims to map potential plastic waste source areas to support upstream waste management interventions. A Geographic Information System (GIS) combined with Multi-Criteria Decision Analysis (MCDA) using a Weighted Linear Combination (WLC) approach was applied to integrate six variables: settlement typology, population density, market distribution, presence of waste facilities, distance to the river, and riverbank condition. Results show that 16.37% of the basin is classified as high-potential, 35.24% as medium, and 48.40% as low-potential. Scenario 1—emphasizing settlement typology and population density—most closely matched field observations, identifying densely populated informal settlements on disturbed riverbanks as the primary contributors to plastic waste leakage. These findings underscore the role of demographic pressure and riverbank settlement characteristics in shaping pollution risks and provide a basis for targeted interventions in high-risk areas.

Abstract

Rainfall distribution in mountainous regions is powerfully shaped by orography, yet detailed spatial understanding in Indonesia remains limited. This study examines orographic precipitation patterns and rain-shadow effects on Mount Rinjani using two main transects, west–east (WE) and north–south (NS), intersecting the Sembalun Valley. As a representative leeward site, Sembalun is the focal point of analysis, with attention to rainfall variability across timescales and the occurrence of extreme events. Daily rainfall data (~1 km resolution) from CHELSA-W5E5, spanning 1979–2016, were analysed. Results reveal sharp contrasts between windward and leeward slopes. Along the WE transect, rainfall rises toward the summit and declines steeply eastward into Sembalun, producing a structured leeward gradient of 22.6 mm per 100 m compared with a more variable 9.0 mm per 100 m on the windward side. Seasonal analysis highlights December–February as the peak rainfall period due to orographic enhancement, whereas shifting monsoonal winds shift the positions of the windward and leeward slopes along the NS transect. Extreme event analysis reveals that over 38 years, more than 25 days exceeded 50 mm on the western slope, while the east recorded far fewer. These findings confirm classical orographic uplift theory while demonstrating its modulation by monsoonal circulation in a tropical island context. They underscore the role of topography in shaping both overall rainfall patterns and precipitation extremes, with implications for hazard risk, irrigation, and tourism in Sembalun. The study provides a scientific basis for climate adaptation, water conservation, and sustainable land-use in the Rinjani region.

Abstract

The problem in teaching Sustainable Development Goals (SDGs) at the high school level is the lack of utilization of technology and the lack of contextual and interactive learning resources. This study aims to develop and implement interactive web-based satellite imagery as a learning media to improve students' understanding of SDG issues, particularly those related to the environment. The interactive web application was developed using the Google Earth Engine platform and Landsat 8, Sentinel-1, Sentinel-2, and Sentinel-5 data. The research method used was a pre-experimental design with a pretest-posttest group. The research subjects were 10th-grade social studies students at SMAN 15 Semarang studying geography lessons on maps, remote sensing, and geographic information systems. Data were collected through observation and tests. A science-based learning approach guided classroom teaching and learning. The results showed that integrating satellite image-based learning media into an interactive web platform increased students' understanding of the SDGs and remote sensing technology by 11%. These results indicate that using remote sensing technology and an interactive web provides an innovative and contextual learning alternative in SDG-based geography education in schools.
