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.
