The threat of a global recession due to the global economic slowdown, rising energy prices, and geopolitical instability has prompted Indonesia to strengthen its economic resilience through energy diversification. One alternative being developed is wood-chip-based biomass as a co-firing fuel in coal-fired power plants to reduce dependence on coal. This study aims to analyze the role of Law No. 11 of 2020 on Job Creation in accelerating the development of biomass-fired power plants and its contribution to national economic resilience. The research method used is normative legal analysis with a legislative and conceptual approach. The results of the study indicate that the Job Creation Law accelerates biomass development through risk-based licensing reforms, simplified environmental approvals, and streamlined forestry permits, thereby enhancing legal certainty for renewable energy investments. These policies also support the acceleration of the biomass supply chain and the implementation of co-firing programs in coal-fired power plants. However, their implementation still faces technical challenges, infrastructure limitations, and the need for policy harmonization across sectors. This study concludes that wood-chip-based biomass power plants have the potential to serve as a strategic instrument in strengthening energy security and national economic stability amid the threat of a global recession.

Comparative Analysis of the Residual Income Valuation Model and the Dividend Discounting Model in Predicting Stock Prices of LQ45 Companies

Icha Mustamin, Amiruddin, Darmawati, Endang Sriningsih — Tue, 02 Jun 2026 00:00:00 +0000

This study aims to analyze and compare the effectiveness of the Residual Income Valuation (RIV) model and the Dividend Discount Model (DDM) in predicting stock prices for companies listed on the LQ45 index of the Indonesia Stock Exchange. Changes in dividend policies and market uncertainty in Indonesia necessitate the use of accurate valuation models for investors and regulators. The research method used is a quantitative comparative study employing a multiple linear regression approach. The sample was determined using purposive sampling, which included LQ45 index companies with complete financial statement data available during the observation period. The effectiveness of the models was measured using statistical instruments and prediction accuracy measures such as Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE). The results of the study indicate that, taken together, net income, book value of equity, and dividends have a significant impact on stock prices, explaining 65.8% of the variance. However, when considered individually, dividends per share were found to be the most dominant and significant variable influencing stock prices (Sig. 0.000). Conversely, net income and book value of equity did not show a significant independent effect. Thus, this study indicates that in the context of LQ45 companies, the Dividend Discount Model (DDM) proves to be more relevant and has stronger predictive power compared to the RIV model. These findings suggest that investors in the Indonesian capital market still heavily rely on dividends as the primary signal of a company’s stability and quality.

The increasing development of modern ballistic threats has encouraged the advancement of lightweight and high-performance body armor materials capable of providing effective protection without reducing user mobility. Graphene, a two-dimensional carbon nanomaterial derived from graphite, has attracted significant attention in defense applications because of its exceptional mechanical properties. This study aims to review graphite-derived graphene-based composites for ballistic body armor applications through relevant national and international journals. The reviewed studies were analyzed based on material characteristics, ballistic energy absorption mechanisms, hybrid composite systems, fabrication methods, and development challenges. The results indicate that graphene improves ballistic resistance through stress-wave propagation, crack deflection, and enhanced energy dissipation mechanisms. In addition, graphene-based hybrid composites demonstrate improved ballistic limit velocity and reduced backface deformation compared to conventional ballistic materials. However, challenges such as high production cost, agglomeration, brittleness, and scalability limitations still hinder large-scale implementation. Overall, graphite-derived graphene shows strong potential for future lightweight ballistic body armor applications.

Leveraging Knowledge Management for Public Sector Organizational Performance: The Mediating Role of Learning Organization

Mandon Febriyanto, Nidya Dudija — Sun, 31 May 2026 00:00:00 +0000

Government agencies need to leverage the intersection of knowledge management (KM) and learning organization (LO) principles to optimize overall organizational performance (OP). Focusing on the Financial Education and Training Agency (BPPK), this research evaluates how the LO serves as a bridge, mediating the impact of KM on OP. A quantitative approach was employed, surveying 276 employees through SEM-PLS analysis. Results indicated that KM substantially improved outcomes through both straightforward effects and intervening processes facilitated by the LO. As a significant partial mediator, LO demonstrated that knowledge assets required a robust learning culture to maximize institutional efficiency. Consequently, public institutions should integrate KM with continuous learning initiatives to foster an agile organization and improve public service delivery.

This study examines the impact of Artificial Intelligence (AI) on learning quality in elementary schools with limited technology infrastructure. Addressing unequal AI adoption, a quasi-experimental design was applied to 130 fifth-grade students divided into AI-based and conventional groups. Data were collected through pretest–posttest and EKOP questionnaires, analyzed using t-tests and reliability measures. Results show the AI group improved from a mean pretest score of 56.65 to 78.85 (gain = 22.20), while the non-AI group increased from 57.15 to 67.60 (gain = 10.45), with significant differences (t = 15.15, p < 0.001). EKOP scores also favored the AI group across all indicators. This study contributes empirical evidence that AI enhances engagement, critical thinking, and learning outcomes in rural elementary contexts.

Development of a Satellite Nozzle-Thruster Design for Geostationary Orbit Deployment: CFD-Based Geometric Optimization for RIDU-Sat

Ahmad Dzakir Nurafif Mahdin, Sumaryadi, Ansori — Thu, 28 May 2026 00:00:00 +0000

The development of an efficient nozzle-thruster is crucial for the RIDU-Sat nanosatellite to reach and maintain geostationary orbit (GEO) with minimal propellant consumption. This study optimizes the geometry of a convergent-divergent nozzle through Computational Fluid Dynamics (CFD) using ANSYS Fluent with hydrogen peroxide as the monopropellant. Three throat diameter variations (0.5 mm, 1 mm, and 2 mm) were tested with a convergent angle of 45° , and a divergent angle of 30° . The results show that the design with a 0.5 mm throat diameter produces the highest exit velocity (1740 m/s), thrust (609 mN), and specific impulse (177 s). The smaller the throat diameter, the higher these three performance parameters become due to more effective supersonic expansion. These findings provide an optimal nozzle design that can improve propulsion efficiency for the geostationary orbit deployment and maintenance maneuvers of RIDU-Sat.

Flight Phase-Based Analysis of Electrical Load and Generator Performance in Boeing 737-500 Using Flight Test Data

Sun, 31 May 2026 00:00:00 +0000

This study analyzes electrical load behavior and engine-driven generator performance on the Boeing 737-500 using real flight test data across all flight phases, including taxi, takeoff, climb, cruise, descent, approach, and landing. The analysis is based on operational parameters such as altitude, airspeed, N1, N2, EGT, fuel flow, oil pressure, oil temperature, and vibration. Results show that the highest electrical loads occur during takeoff and climb due to anti-ice operation, bleed air demand, and maximum thrust settings, while the cruise phase at FL350 provides the most stable operating condition with balanced load distribution and minimal frequency fluctuation. Moderate load changes occur during descent as system configurations transition. Overall, generator performance remains stable throughout all flight phases without imbalance or frequency deviation. Unlike previous simulation-based studies, this research provides empirical evidence from actual aircraft operations, contributing to condition-based maintenance development and aircraft electrical system monitoring frameworks.

Mapping the E-Government Portrait of Malang City: A Cross-Platform Meta-Synthesis of Sixty Public Administration Undergraduate Theses, 2024–2025

Bayu Indra Pratama, Muhammad Rizki Pratama — Mon, 01 Jun 2026 00:00:00 +0000

This study proposes a qualitative meta-synthesis framework applied to sixty undergraduate theses from Universitas Brawijaya graduating in 2024–2025 that examine e-government practice in Malang City. Drawing on Noblit and Hare’s meta-ethnography, eMERGe reporting, and PRISMA 2020 corpus selection, the work maps the corpus across at least twenty-three municipal digital platforms, reads each thematic cluster substantively, and weaves seven preliminary line-of-argument patterns. Citizen-interface depth predicts platform success more strongly than architectural completeness; nationally mandated platforms yield thinner local public value than locally originated ones; and a co-production gap pervades the corpus except in the disability-inclusion cluster. The framework offers theoretical, methodological, and practical contributions.

Asri Alkadri, Suryo Ediyono — Mon, 01 Jun 2026 00:00:00 +0000

Waste banks have emerged as an innovative community-based approach to environmental management and education, particularly in developing countries facing increasing waste generation and low public awareness of sustainable practices. This systematic review examines the effectiveness, educational strategies, and implementation challenges of waste banks as tools for environmental education. The review synthesizes findings from various studies published in recent years, focusing on how waste banks influence environmental awareness, waste sorting behavior, recycling participation, and community engagement. The findings indicate that waste banks contribute positively to environmental education by encouraging active participation, improving public knowledge about waste management, and fostering sustainable habits among students and communities. Educational strategies commonly applied include participatory learning, social campaigns, school-based activities, and economic incentives that motivate behavioral change. However, several implementation challenges remain significant, including limited financial support, inadequate infrastructure, inconsistent community participation, weak policy integration, and insufficient managerial capacity. In addition, differences in local socio-cultural conditions often affect the sustainability and effectiveness of waste bank programs. Overall, this review highlights that waste banks are not only waste management initiatives but also valuable educational instruments for promoting environmental responsibility and sustainable development. Strengthening institutional support, stakeholder collaboration, and educational integration is essential to maximize their long-term impact.

An Exegetical Study of the Good Samaritan (Luke 10:25–37) as a Model of Caring in Nursing Practice

Nova Lina Langingi, Grace Fresania Kaparang — Sun, 31 May 2026 00:00:00 +0000

Caring is widely recognized as the essence of nursing practice and remains central to holistic patient care. Contemporary nursing literature increasingly emphasizes compassion, empathy, and spiritual care as essential dimensions of professional nursing. Within Christian nursing education, biblical narratives may provide foundational insights into caring behaviors and holistic healing. This study explores the Good Samaritan narrative in Luke 10:25–37 as a model of caring relevant to nursing practice. Using qualitative biblical exegesis and thematic content analysis, the study identifies key caring themes embedded within the narrative and relates them to Jean Watson’s Theory of Human Caring. The findings reveal seven major caring themes: compassion, presence, caring action, holistic care, sacrifice, advocacy, and human dignity. These themes demonstrate strong parallels with contemporary nursing caring theory and support the integration of biblical perspectives into holistic nursing education and practice. Also, implementing this model requires nurses’ reflective awareness to bridge the gap between administrative demands and patients’ emotional needs. The study contributes to faith integration scholarship by providing a theological and theoretical framework for understanding caring within Christian nursing. Future research may explore other biblical healing narratives and their relevance to nursing, leadership, ethics, and spiritual care.

The Dialectic of Digital Communication Transformation in Occupational Safety and Health (OSH): Between the Rationality of Technological Efficiency and Workers’ Psychosocial Well-Being

L.M. Zainal Abidin K, Suryo Ediyono — Sun, 31 May 2026 00:00:00 +0000

The digital communication revolution has fundamentally transformed the occupational safety and health (OSH) landscape through the adoption of Artificial Intelligence (AI), the Internet of Things (IoT), Virtual Reality (VR), and various digital communication platforms. This study aims to analyze the dialectic between the rationality of technological efficiency and workers’ psychosocial well-being in the context of digital communication transformation in OSH. Using a qualitative approach through a systematic literature review, this study integrates four theoretical frameworks: Diffusion of Innovations (Rogers, 2003), the Technology Acceptance Model (Davis, 1989), the Job Demands–Resources Model (Demerouti et al., 2001), and the Socio-Technical approach (Trist & Emery, 1960). The study’s findings indicate that while digital communication technologies significantly enhance the effectiveness of workplace safety communication, their implementation must take into account workers’ overall psychosocial well-being. From the perspectives of work humanism and the philosophy of technology, the digitalization of occupational safety and health (OSH) should not be solely focused on production efficiency, but rather aimed at creating a balance between technological capabilities and the human dignity of workers. This study recommends the integration of a participatory development communication approach, the application of digital ergonomics principles, and the development of OSH policies that are responsive to the psychosocial dynamics of the digital workplace.

Analysis of the Sociopetal-Sociofugal Architectural Conflict (SSAC) in High-Density Vernacular Sundanese Restaurants

Muhamad Sugeng Riyadi, James ED Rilatupa, Yophie Septiady — Sun, 31 May 2026 00:00:00 +0000

Vernacular restaurant architecture in Indonesia increasingly deploys enclosed saung pavilions as spatial differentiators, yet the operational consequences of this design choice remain poorly understood. This study identifies the Sociopetal-Sociofugal Architectural Conflict (SSAC) a structural paradox in which the saung simultaneously creates intimate, comfortable conditions for dining guests while imposing navigational and communicational burdens on service staff. Grounded in Hall's Proxemics theory, Ching's architectural elements framework, and Bitner's Servicescape model, this research conducts qualitative field observation and behavioral mapping at Gurih 7 Restaurant in Bogor, Indonesia. The goal is to document and analyze how a single architectural typology produces opposing proxemic effects for two distinct user groups, and to establish the SSAC as a theoretically grounded phenomenon for recognition in future vernacular restaurant design and research.

Global Trends in Teacher Management: Evidence from a Global Bibliometric Systematic Review (2020–2026)

Andi Nur Qalbi, Ardiansyah, Anshar — Thu, 28 May 2026 00:00:00 +0000

This study develops an integrative perspective on teacher management by addressing the fragmentation that characterizes much of the existing literature. Using a Systematic Literature Review (SLR) combined with bibliometric analysis, the study examines global research trends from 2020 to 2026. Data were retrieved from Scopus, Web of Science, and Google Scholar, resulting in 50 initial records, which were systematically filtered using the PRISMA protocol into 50 relevant articles. The findings reveal a substantial increase in scholarly attention to teacher management, particularly after the COVID-19 pandemic. More importantly, the focus of research has shifted from administrative concerns toward more complex dimensions, including teacher wellbeing, retention, and digital competence. Bibliometric mapping identifies four dominant clusters: professional development, teacher retention and motivation, digital transformation, and teacher wellbeing. Building on these insights, this study proposes an integrative model of teacher management that connects recruitment, distribution, professional development, and wellbeing within a systemic and adaptive framework. The analysis also highlights a divergence between developed and developing countries, emphasizing the importance of contextual adaptation. In the Indonesian context, this implies aligning global practices with local realities. This study contributes by bridging bibliometric evidence with comparative analysis, offering both theoretical integration and practical insights for sustainable education policy.
