The growing energy demand in areas lacking access to modern infrastructure drives the development of biomass-based thermal technologies, such as the dual-chamber downdraft gasification stove. This stove offers higher efficiency and lower emissions compared to direct combustion but still poses failure risks in various system components. This study aims to identify critical failure modes affecting the thermal efficiency of the stove through the Failure Mode and Effect Analysis (FMEA) approach. The analysis involved mapping the system's structure and functions, followed by evaluating failure modes using three parameters: Severity (S), Occurrence (O), and Detection (D) to obtain the Risk Priority Number (RPN). Results indicate the highest risk occurs in the combustion system (RPN 180), followed by the air control system (RPN 160). Key causes include suboptimal secondary air distribution and valve blockage. Other systems such as insulation, maintenance access, safety, and fabrication had lower RPNs but still require design and quality control improvements. Recommendations focus on improving airflow design, using high-temperature-resistant materials, and adopting precision fabrication procedures. Using the FMEA approach, the gasification stove can be enhanced in terms of reliability, efficiency, and user safety, making it more feasible as a small-scale renewable energy solution for communities.

The rapid advancement of information technology and digitalization has significantly transformed the financial sector, particularly with the emergence of cryptocurrencies characterized by high price volatility and complex movement patterns. Accurate price prediction of these crypto assets is essential to support investment decision-making and risk management. This study aims to compare the performance of six activation functions ReLU, Tanh, Sigmoid, Softplus, Swish, and Mish in a Simple Recurrent Neural Network (RNN) model for predicting the price of Litecoin, a widely traded cryptocurrency. Using historical daily closing price data from May 2020 to April 2025, the data were preprocessed through Min-Max normalization and sliding window sequence formation to fit the RNN input requirements. Each activation function was applied in the RNN model under consistent training conditions, and model performance was evaluated using Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and coefficient of determination (R²). Results indicate that the Swish activation function outperforms others by achieving the lowest RMSE of 4.58 and the highest R² score of 0.9578, demonstrating superior prediction accuracy and stable convergence. Tanh also showed competitive results, while Sigmoid and Softplus performed less effectively. In conclusion, Swish is recommended as the most suitable activation function for RNN-based cryptocurrency price forecasting due to its balance of accuracy and computational efficiency.

This study aims to analyze gaps in the implementation of Law Number 8 of 2016 concerning Persons with Disabilities in Indonesia. This law is an effort by the Indonesian government to provide more comprehensive legal protection for persons with disabilities, in line with the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD). Using a literature analysis approach, this study identified five main gaps in the implementation of the law: limited physical and digital accessibility, lack of participation of persons with disabilities in the decision-making process, disparities in implementation at the regional level, unavailability of accurate data, and ongoing social stigma and discrimination. The research methodology is qualitative descriptive with secondary data sources in the form of literature, laws and regulations, government reports, journal articles, and other credible publications. The results of the study indicate that many public facilities are not yet fully disability-friendly, participation of persons with disabilities in policy forums is still minimal, there are gaps in implementation between regions, data on persons with disabilities has not been integrated, and negative stigma is still strong in society. Based on these findings, this study recommends strengthening accessibility regulation and monitoring, institutionalizing representation of persons with disabilities in policy-making, providing technical and budgetary assistance to reduce regional disparities, developing an integrated national database, and anti-stigma education campaigns. The implementation of these recommendations is expected to realize more effective legal protection and social inclusion for persons with disabilities in Indonesia.

Digital transformation has fundamentally changed television broadcasting management in Southeast Asia. This study examines two countries, Indonesia and Malaysia, which are at different stages of digital adoption. A qualitative research method with a case study approach is used, combining an international literature review, policy documents, and semi-structured interviews with broadcast practitioners. Thematic and comparative analysis, framed by the Dynamic Capabilities Framework, uncovers three main aspects: (1) organizational restructuring and multi-platform strategies; (2) technology adoption including DVB-T2 infrastructure, IP-based production systems, and AI for content recommendation; and (3) business model innovation through digital revenue diversification (YouTube, programmatic advertising, and OTT). The results show that Malaysia benefits from centralized policies and early infrastructure readiness, while Indonesia still faces challenges of decoder ownership, regional digital divide, and legacy-new system integration. Both countries emphasize the importance of human resource training, public-private collaboration, and incentive policies to accelerate digital adoption. Recommendations for the study include strengthening dynamic organizational capabilities, funding innovation, and digital literacy programs for the community. These findings provide strategic guidance for stakeholders to optimize broadcasting management in the digital era, towards an inclusive, adaptive, and sustainable ecosystem.

In an era of increasingly rapid modernization, the sustainability of TAK faces serious challenges, ranging from rural-urban migration, formal curricula that ignore local content, and declining interest among the younger generation in agricultural practices based on local wisdom. Using a qualitative ethnographic approach, this study uncovers inheritance patterns, transmission channels, inhibiting factors, and potential for revitalization. The results indicate a generational gap, with elders still maintaining knowledge retention rates above 90%, while younger generations retain only around 25%. Nevertheless, opportunities for revitalization emerge through community initiatives, the integration of TAK into local curricula, and the development of technology-based agroecological entrepreneurship. This study confirms that cross-generational collaboration, policy support that recognizes the value of local knowledge, and the synergy between tradition and innovation are key to TAK's sustainability. Thus, TAK is not only a cultural heritage, but also a strategic resource for food security, biodiversity conservation, and strengthening the ecological identity of indigenous communities in an era of socio-ecological change.

The advancement of robotics technology has supported the integration of efficient navigation systems into STEM-based learning (Science, Technology, Engineering, and Mathematics), particularly in technical and vocational education. One essential component in robot navigation is the distance sensor, with ultrasonic sensors widely adopted due to their ease of integration into project-based learning. This study aims to analyze the performance of three ultrasonic sensors—HC-SR04, HY-SRF05, and RCWL-1601 within the context of Arduino-based microcontroller projects used as educational tools for robotics instruction. Performance analysis was carried out in terms of measurement accuracy, data stability, and response time. The results show that the HY-SRF05 sensor achieved the highest accuracy (96.75%) and the lowest standard deviation (0.23 cm), indicating the most stable performance. The HC-SR04 sensor showed relatively high accuracy but greater data variation, while the RCWL-1601 had the fastest response time but less stable measurements, especially on non-reflective surfaces. These findings can serve as a practical reference for selecting appropriate sensors in project-based teaching activities, particularly in developing robotics learning media that require precision and consistent data. Future research will focus on applying signal processing algorithms such as the Kalman filter and integrating these technologies into technical education curricula.

Indonesia, the world's largest archipelagic nation, faces long-standing inequality in the distribution of healthcare workers, particularly in its eastern regions such as Papua, Maluku, and East Nusa Tenggara. This study investigates the structural causes of health workforce maldistribution and the limited success of physician retention programs over the last decade. Using a descriptive qualitative approach, the study combines a systematic literature review, policy document analysis, and secondary data evaluation, including findings from recent Discrete Choice Experiments (DCE) involving over 500 physicians. Results reveal that despite government programs like Nusantara Sehat and mandatory rural service, the national ratio of healthcare workers (3.84 per 1,000 population) remains below the WHO standard for Universal Health Coverage (UHC), and retention in remote areas is still critically low (<25% after two years). Regional disparities persist, with Papua and NTT suffering from the highest shortages up to 48% of community health centers lack doctors. The DCE findings confirm that non-monetary factors such as guaranteed safety, adequate hospital infrastructure, career development opportunities, and legal housing significantly influence physician retention, more so than financial incentives alone. Policy interventions remain fragmented and overly reliant on temporary placement incentives, without addressing systemic issues such as geographic isolation, weak intersectoral coordination, and limited rural training pathways. In response, the study recommends a shift toward holistic, long-term solutions, including CBME-based medical education, integrated specialist training in remote areas, expanded telemedicine capacity, and real-time health workforce planning systems. Addressing the maldistribution of healthcare workers is vital not only for equity in health access but also for national development. With coordinated, evidence-based policy reform, Indonesia has the potential to strengthen rural healthcare systems and accelerate progress toward its 2030 SDG and UHC targets.
