This study investigates regional heterogeneity and spatial interdependence in digital skills mismatch across Indonesia by constructing a Digital Skills Supply–Demand Ratio (DSSDR) from the Indonesia Digital Society Index (IMDI). In line with SDG 10 (Reduced Inequalities) and SDG 4 (Quality Education), the study aims to provide policy-relevant evidence to support a more inclusive and balanced digital transformation. Using district-level data and spatial econometric models (OLS, SAR, and the SDM), the analysis evaluates both local determinants and cross-regional spillover effects. Model comparison identifies the Spatial Durbin Model as the best specification, revealing strong spatial dependence in digital skills imbalance. The results show that most local socioeconomic and digital readiness indicators do not have significant direct effects on DSSDR, while school internet coverage exhibits a consistently negative association, indicating that digital demand expands faster than local supply. In contrast, spatial spillovers are decisive: a higher share of ICT study programs in neighboring regions improves local DSSDR through knowledge and human-capital diffusion, whereas higher GRDP per capita in adjacent regions exacerbates local mismatch, consistent with a talent-attraction mechanism. These findings demonstrate that digital skills mismatch is a spatially interconnected phenomenon driven more by interregional dynamics than by local conditions alone, implying that policy responses should move beyond isolated district-level interventions toward coordinated regional strategies integrating education systems, labor markets, and digital ecosystem development. The study contributes a spatially explicit, supply–demand-based framework for diagnosing regional digital inequality and supporting more equitable and sustainable digital development in Indonesia.

Building resilient and sustainable energy systems is a critical challenge for disaster-prone regions in the Global South. This study investigates the energy management of a networked microgrid (NMG) system on Lombok Island, Indonesia, a region frequently exposed to natural disasters (NDs) and characterized by vulnerable grid infrastructure. A multi-objective optimization framework is developed to jointly minimize operational costs, load-not-served, and environmental impacts under both normal and abnormal operating conditions. The proposed strategy employs the Multi-objective JAYA (MJAYA) algorithm to coordinate photovoltaic generation, diesel generators, battery energy storage systems, and inter-microgrid power exchanges within a 20 kV distribution network. Using real load, generation, and electricity price data, we evaluate the NMG’s performance under five representative fault scenarios that emulate ND-induced outages, including grid disconnection and loss of inter-microgrid links. Results show that the interconnected NMG structure significantly enhances system resilience, reducing load-not-served from 366.3 kWh in fully isolated operation to only 31.7 kWh when interconnections remain intact. These findings highlight the critical role of cooperative microgrid networks in strengthening community-level energy resilience in vulnerable regions. The proposed framework offers a practical decision-support tool for planners and governments seeking to enhance energy security and advance sustainable development in disaster-affected areas.

This study investigates the institutional transformations within Indonesia’s research ecosystem, focusing on the impacts of the National Research and Innovation Agency (BRIN) establishment and the subsequent Work From Office (WFO) policy on the Association of Indonesian Researchers (PPI). The research aims to evaluate these impacts and propose an adaptive institutional revitalization model. Employing a mixed-methods approach, a total of 150 online questionnaires were distributed across 21 regional branches of PPI between February and March 2025. Of these, 87 were completed and valid for analysis, representing a 58% response rate. Findings reveal that the WFO policy has led to a significant decline in member participation, coordination difficulties across regions, and weakened collaboration with local partners such as regional governments and universities. A SWOT analysis of three revitalization options—full agglomeration, bounded agglomeration, and non-BRIN integration—identified a hybrid model as the most adaptive and widely supported alternative (41.5%). This hybrid model combines selective structural efficiency with inclusive membership expansion, aiming to preserve regional identity, enhance collaboration, and strengthen organizational legitimacy. The study offers key insights for developing adaptive governance frameworks rooted in epistemic justice, digital accountability, and cross-sectoral collaboration, applicable to professional organizations navigating decentralization and institutional disruption. The proposed hybrid model serves as a strategic reference for achieving organizational resilience and fostering a more inclusive national innovation ecosystem. Full article

Agrivoltaics (APV) offers a promising dual land-use solution for food and energy production, yet empirical data regarding its impact on leguminous crops in tropical monsoon climates remain limited. This study evaluated the microclimate, growth, and yield of soybean (Glycine max) under an APV system compared to an open-field control during the wet and dry seasons in Bogor, Indonesia. The APV structure reduced incident solar radiation by approximately 35%, significantly lowering soil temperatures and maintaining higher soil moisture across both seasons. In the wet season, the APV treatment significantly increased grain yield (3528.8 vs. 1708.3 kg ha⁻¹, +106%) relative to the open field by mitigating excessive heat and radiative loads, which enhanced pod retention. In the dry season, APV maintained a yield advantage (2025.6 vs. 1724.4 kg ha⁻¹, +17%), driven by improved water conservation and a higher harvest index. Notably, shading did not delay phenological development or hinder vegetative growth in either season. These findings demonstrate that APV systems can contribute to sustainably higher yields and stability in tropical environments by buffering against season-specific environmental stresses, suggesting a viable pathway for sustainable agricultural intensification in equatorial regions.

Rapid urbanization in developing megacities has exacerbated hydrological imbalances, positioning urban flooding as a major environmental and socio-economic challenge of the twenty-first century. This study investigates the spatial relationship between building density, topography, and flood susceptibility in Jakarta, Indonesia—one of the most flood-prone urban regions globally. Employing geospatial analysis and spatial autocorrelation techniques, the research assesses how variations in land-use concentration and elevation influence the spatial clustering of flood vulnerability. The analytical framework integrates multiple spatial datasets, including Digital Elevation Models (DEMs), building footprint densities, and flood hazard maps, within a Geographic Information System (GIS) environment. Spatial statistical measures, specifically Moran’s I and Local Indicators of Spatial Association (LISA), are utilized to quantify and visualize patterns of flood susceptibility. The findings reveal that zones characterized by high building density and low elevation form statistically significant clusters of heightened flood risk, particularly within the southern and eastern subdistricts of Jakarta. The study concludes that incorporating spatially explicit and statistically rigorous methodologies enhances the accuracy of flood-risk assessments and supports evidence-based strategies for sustainable urban development and resilience planning.

Indonesia’s beef cattle sector plays a central role in achieving food security, enhancing rural livelihoods, and fostering economic resilience. However, it faces fragmented governance, import dependence, and persistent challenges of low productivity levels. To capture the evolving evidence base, this study conducted a scoping review of 61 peer-reviewed publications (2019–2025) drawn from six major databases. This study employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review Protocol and Arksey and O’Malley’s framework. Key patterns, advances, and gaps, along with evidence and research recommendations, were identified using the PAGER analytical approach. The dominant themes include production efficiency, environmental sustainability, policy, market linkages, and technological innovation. The results show that most studies employed quantitative or system modelling designs. In the global literature, multidimensional sustainability frameworks have shifted away from production-centric ones, with regional studies highlighting different emphases, such as carbon metrics in South America and market access and livelihood resilience in Asia and Africa. Integrated crop, livestock, and forestry systems; legume-based nutrient management; genotype-specific feeding and breeding; and enabling policies within inclusive markets were revealed through the synthesis of the PAGER framework as four calculated levers for sustainable transformation. However, actors inadequately integrate feed, genetic, climate interactions, and governance mechanisms. According to this review, technological innovation must align with adaptive governance. Climate-resilient, low-carbon beef systems also require the development of inclusive institutional frameworks. Indonesia’s experience demonstrates the benefits of integrating science, policy, and the market to improve productivity, resource stewardship, and equity in tropical livestock systems, thereby enhancing a resilient agri-food supply chain in Indonesia.

In disaster-prone regions facing chronic housing shortages and growing sustainability demands, modern construction methods are essential to achieving resilience, affordability, and rapid delivery. Modular construction, one of the core components of Modern Methods of Construction (MMC), offers significant potential but remains underutilized in developing contexts due to regulatory, managerial, and technical constraints. This study investigates the multi-stakeholder priorities influencing the adoption of modular construction in Indonesia, with a particular focus on Aceh, a province frequently affected by natural disasters. An integrated Analytic Hierarchy Process (AHP) and Monte Carlo simulation framework was applied to evaluate six main criteria and sixteen sub-criteria, drawing on expert input from five stakeholder groups: academics, planners, architects, consultants, and contractors. The results indicate that Managerial and Planning (0.181), Quality, Safety and Regulation (0.178), and Human Resources and Knowledge (0.174) are the most influential criteria. Among five modular alternatives, Volumetric Modular ranked highest (0.243) for its rapid deployment and disaster-resilient characteristics, followed by Panelized Modular (0.203). Monte Carlo sensitivity testing validated the robustness of these results under uncertainty. This research represents one of the first probabilistic, multi-stakeholder assessments of modular adoption in a developing-country disaster context. Policy implications highlight the urgent need for regulatory reform to standardize modular practices and workforce training programs to strengthen technical capacity, thereby accelerating resilient housing delivery in Aceh and similar regions.

This paper examines community resilience in addressing clean water scarcity in Salaon Toba Village, Ronggur Nihuta Subdistrict, Samosir District, North Sumatra, Indonesia. Although the Lake Toba region is abundant in water resources, many surrounding settlements continue to face difficulties in accessing safe and reliable water. Using a descriptive qualitative method, the study engaged 20 informants through in-depth interviews and direct observations to explore the challenges and strategies adopted by local residents. The findings reveal that, despite the village’s proximity to Lake Toba, geographical and geological conditions—such as rocky highland terrain—significantly limit water availability, especially during the rainy season. To cope with these constraints, communities employ diverse adaptive strategies, including purchasing water transported from Lake Toba, harvesting rainwater from rooftops, constructing large storage tanks inside and outside homes, implementing strict water-saving routines, and organizing water-related responsibilities along gender lines. While Salaon Toba has access to multiple water sources—springs, rainwater, Lake Toba, and Lake Pea Porohan—their full utilization remains constrained by technical limitations, cultural restrictions, and inadequate infrastructure. These strategies highlight the community’s agency in sustaining daily needs, yet also underline the urgent need for government intervention to ensure equitable and sustainable access to clean water. The study emphasizes the importance of inclusive policies aligned with Sustainable Development Goal 6 [Clean Water and Sanitation] to strengthen both infrastructure and community resilience in facing climate-induced water challenges.

This study examines how environmental journalists in Eastern Indonesia develop innovative digital strategies to counter corporate disinformation while maintaining credible climate reporting amid systematic censorship and algorithmic suppression. Through ethnographic fieldwork with 34 environmental journalists in Makassar and surrounding maritime communities (2023–2024), combined with digital platform analysis and content verification tracking, this investigation reveals how local journalists create “networked verification archipelagos” that mirror traditional maritime communication systems to combat extractive industry misinformation. Our analysis revealed three primary counter-disinformation mechanisms: (1) community-based verification networks that successfully identified 87% of corporate misinformation within 48 h through traditional knowledge integration; (2) algorithmic resistance strategies that increased environmental content visibility by 156% through cultural framing techniques; and (3) cross-platform coordination that maintained journalist communication networks despite 34 documented censorship campaigns. These networks enable accurate environmental reporting despite corporate-sponsored disinformation campaigns, government restrictions on mining coverage, and social media algorithms that amplify climate denial content. The research demonstrates how journalists in the Global South develop decolonial approaches to counter-disinformation that challenge Western platform-centric fact-checking models while maintaining journalistic credibility and community accountability. These findings contribute to understanding power dynamics and coloniality in disinformation studies while offering insights for media literacy and democratic integrity in climate-vulnerable regions.

Background/Objectives: Local production is a global priority for increasing access to routine, outbreak, and pandemic vaccines and leads to a variety of direct and indirect benefits for countries. This study aimed to characterize the enabling environment for the sustainable production of influenza vaccines, including for epidemic and pandemic preparedness. Methods: National/local vaccine manufacturers were surveyed to capture data on influenza vaccine market contributions, government support for local production, and involvement in national pandemic preparedness activities. Using a conceptual framework for sustainable local production of influenza vaccines for epidemic and pandemic preparedness, manufacturers described 41 global/regional, national, and institutional sustainability factors across policy, health system, research and development (R&D), and regulatory thematic domains. In addition to the survey, key findings from country-level sustainability assessments of vaccine production in Bangladesh, Brazil, Indonesia, Serbia, and Viet Nam were analyzed to complement survey results. Results: This study included 12 participants representing 11 manufacturers from 10 countries. Of the 11 manufacturers, six reported that their countries have policies that support local production, but most manufacturers reported benefiting from some level of direct or indirect support by the government. Manufacturers considered 40/41 factors as important for sustainable production of influenza vaccines, and among the four domains, influenza prevention and control policies, influenza burden data, quality management, and regulatory filing capacity ranked highly. Additionally, manufacturers ranked factors related to cohesive policies for local production promotion and business/strategic planning at the manufacturer level as the top sustainability factors. Conclusions: Manufacturers broadly agreed on the importance of cohesive policies, evidence-based public health priorities, robust R&D and manufacturing investments, and regulatory readiness, though perceptions varied across contexts and company characteristics. Sustainable local production of influenza vaccines should be driven by the alignment of policies, investments, and demand. Full article

This study compares certification systems for green healthcare facilities implemented worldwide. Healthcare facilities are complex structures designed to provide uninterrupted service while involving substantial resources, high energy consumption, and heavy human and material traffic. The COVID-19 pandemic emphasized the importance of designs that ensure hygiene, reduce environmental impact, and improve energy efficiency, making green certification systems for healthcare facilities increasingly critical. Eight certification systems currently in use across eight countries were examined, four from advanced economies (LEED in the U.S., BREEAM in the U.K., Green Star in Australia, and CASBEE in Japan) and four from developing economies (YeS-TR in Türkiye, IGBC in India, GBI in Malaysia, and GREENSHIP in Indonesia). Country selection considered regional diversity, similarities in environmental policies, and the potential for healthcare infrastructure development. A literature-based comparative analysis was conducted, and seven key categories were identified for evaluating sustainability: sustainable land and transport, water and waste management, energy efficiency, material and life cycle impact, indoor environmental quality, project management process, and innovation. The comparison revealed considerable overlap among the systems but also highlighted shortcomings in addressing healthcare-specific needs. This paper contributes to the advancement of sustainability assessment in the healthcare sector by highlighting the need for certification schemes specifically designed for medical facilities. The findings emphasize the necessity of developing healthcare-tailored frameworks that not only address environmental performance but also capture the unique operational, functional, and clinical dynamics of this sector.

Rapid urbanization in developing regions presents a critical challenge to the provision of affordable housing. This systematic review, conducted following the PRISMA 2020 guidelines, analyzed 91 studies (2013–2024) from Scopus and Google Scholar to identify cost-effective materials and innovative techniques suitable for the developing context. Findings reveal that achieving affordability in developing regions requires a holistic approach that integrates material innovation with human capacity building. The analysis of critical success factors (CSFs) in the Rumah Unggul Sistem Panel Instant (RUSPIN) system from Indonesia and the Recycled Plastic Formwork (RPF) system from South Africa exemplifies this integration. Both systems show high potential for scalability and technological transfer using local materials and labor training. The review also highlights that materials commonly used in developed countries (e.g., autoclaved aerated concrete, expanded polystyrene, and light steel gauge framing) face adoption barriers in developing regions due to challenges related to supply chains, industry capacity, and regulatory frameworks. Conversely, locally available materials (e.g., earth, bamboo, and recycled waste) require ongoing research to enhance their availability and structural performance. Ultimately, achieving affordable housing depends on an integrated approach that combines locally sourced materials, innovative construction techniques, and the strategic application of critical success factors.

Accurate estimation of global horizontal irradiance (GHI) is essential for optimizing photovoltaic (PV) systems, particularly in regions with distinct climatic characteristics. Geostationary satellites, such as GK2A and COMS, provide consistent and spatially extensive data, offering a practical alternative to ground-based measurements. However, the performance of semi-empirical GHI models has been sparsely evaluated across diverse geographic zones. This study aimed to conduct a comparative analysis of four semi-empirical models—Beyer, Rigollier, Hammer, and Perez—applied to two contrasting locations: Seoul, South Korea (temperate) and Jakarta, Indonesia (tropical). Using satellite-derived cloud indices and ground-based pyranometer data, model performance was evaluated via RMSE, MBE, and their relative metrics. Results indicate that the Hammer model achieves the best performance in Seoul (RMSE: 103.92 W/m²; MBE: 0.09 W/m²), while the Perez model outperforms others in Jakarta with the lowest relative RMSE of 58.69%. The analysis outlines the limitations of transferring models calibrated in temperate climates to tropical settings without regional adaptation. This study provides critical insights for improving satellite-based GHI estimation and supports the development of region-specific forecasting tools essential for expanding solar infrastructure in Southeast Asia.

Buildings in Indonesia’s tropical climate face significant barriers to energy efficiency due to high cooling loads and electricity intensity. Previous studies have primarily addressed technical optimization or policy frameworks, but few have provided an integrated and data-driven evaluation model for tropical conditions. This study develops an Internet of Things (IoT) and EDGE-based hybrid framework to support the transition toward Net-Zero-Energy Buildings (NZEBs) while maintaining occupant comfort. The research combines real-time IoT monitoring at the LLDIKTI Region XIII Office Building in Banda Aceh with simulation-based assessment using Excellence in Design for Greater Efficiencies (EDGE). Baseline energy performance was established from architectural data, historical electricity use, and live monitoring of HVAC systems, lighting, temperature, humidity, and CO₂ concentration. Intervention scenarios—including building envelope enhancement, lighting optimization, and adaptive HVAC control—were simulated and validated against empirical data. Results demonstrate that integrating IoT-driven control with passive design measures achieves up to 31.49% reduction in energy use intensity, along with 24.7% improvement in water efficiency and 22.3% material resource savings. These findings enhance indoor environmental quality and enable adaptive responses to user behavior. The study concludes that the proposed IoT–EDGE framework offers a replicable and context-sensitive pathway for achieving net-zero energy operations in tropical office buildings, with quantifiable environmental benefits that support sustainable public facility management in Indonesia.

This study develops a geomorphological identification methodology for wall reefs in the microcontinental environment of Wangiwangi Island, Indonesia, using medium-resolution Landsat 8 satellite imagery and morphological analysis based on Maxwell’s geomorphological framework. The uniqueness of the wall reef landform lies in the fact that the lagoon elongates on limestone, resulting in a habitat and ecosystem that develops differently from those of other shelf reefs, namely, platform reefs and plug reefs. Using Optimum Index Factor (OIF) optimization and RGB image composites, four reef types were successfully identified: cuspate reefs, open ring reefs, closed ring reefs, and resorbed reefs. A field check was conducted at fifteen observation sites, which included measurements of depth, turbidity, and water quality parameters, as well as an in situ benthic habitat inventory. The analysis results showed a strong correlation between image composites, geomorphological reef classes, and ecological conditions, confirming the successful adaptation of Maxwell’s classification to the Indonesian reef system. This hybrid integrated approach successfully maps the distribution of reefs on a complex continental shelf, providing an essential database for shallow-water spatial planning, ecosystem-based conservation, and sustainable management in the Coral Triangle region. Policy recommendations include zoning schemes for protected areas based on reef landform morphology, strengthening integrative monitoring systems, and utilizing high-resolution imagery and machine learning algorithms in further research.
