This study investigates the strategic strengthening of the rambak cracker industry as an instrument for local economic development in Penanggulan Village, Pegandon District, Kendal Regency. Rural agro-processing enterprises have increasingly been recognized as territorially embedded production units capable of generating value-added outputs and absorbing surplus labor within localized economic systems. Field-based empirical observations reveal that rambak production in the village operates through household-managed processing systems characterized by traditional production techniques, informal managerial practices, and limited digital marketing adoption despite contributing significantly to community income generation. Data obtained from expert respondents were analyzed using the Analytical Hierarchy Process to identify strategic priority determinants influencing industrial competitiveness and sustainability. The results indicate that product innovation and quality improvement constitute the primary strategic priority, followed by digital marketing development and institutional partnership strengthening, while production capacity expansion remains comparatively less influential in enhancing market competitiveness. These findings suggest that adaptive innovation and digitally enabled commercialization pathways function as critical mechanisms for improving value-chain integration and expanding market accessibility among rural food-processing industries. Strengthening innovation ecosystems within the rambak sector may therefore contribute to employment creation, income diversification, and sustainable community-based economic transformation in rural production clusters.

This study investigates Indonesia’s long-term economic transformation across four pivotal eras: the colonial period, the Old Order, the New Order, and the Reformasi era. Employing a descriptive qualitative design with historical analysis, the research elucidates how political transitions, institutional reforms, and global dynamics have interacted to shape the nation's economic architecture. Results indicate that colonial legacies entrenched deep structural inequalities and a dualistic economy, creating a path dependency that continued to influence policy direction after independence. During the Old Order, efforts to assert economic sovereignty were constrained by macroeconomic instability, limited state capacity, and shifting political coalitions. The New Order marked a turning point toward industrialization, macroeconomic stabilization, and openness to foreign investment, generating high growth but also deepening inequality and dependence on external capital. Entering the Reformasi era, decentralization, democratization of governance, and fiscal transparency reshaped institutional frameworks; however, persistent challenges such as regional disparities, productivity gaps, and vulnerability to global shocks remain evident. The study concludes that Indonesia’s economic evolution is non-linear, shaped by historical constraints and gradual institutional adaptation rather than abrupt shifts. Strengthening governance, enhancing domestic industrial competitiveness, and expanding inclusive development policies are essential strategies for supporting long-term resilience. These findings highlight the importance of continuity in policy reform to achieve sustainable growth and to realize the national vision of Indonesia Emas 2045.

Background: The development of industrial technology in the Industry 4.0 era has encouraged the implementation of intelligent monitoring systems to improve machine reliability and operational efficiency. However, machine fault diagnosis systems based on artificial intelligence often face limitations in terms of interpretability because the models used are complex and difficult to explain. Objective: This study aims to develop a deep learning-based industrial machine fault diagnosis system integrated with an Explainable Artificial Intelligence (XAI) approach to improve diagnostic accuracy while providing interpretable insights for users. Method: The research method involves collecting data from industrial machine sensors consisting of vibration signals, temperature measurements, and acoustic signals, followed by data preprocessing and feature extraction processes. The processed data are then used to train a deep learning-based diagnostic model, after which explainability methods such as SHAP or LIME are applied to analyze the contribution of each feature to the model’s prediction results. Model performance is evaluated using accuracy, precision, recall, and F1-score metrics. Results: The results indicate that the proposed deep learning model achieves better performance compared to conventional machine learning methods such as Support Vector Machine and Random Forest. Furthermore, the explainability analysis reveals that vibration amplitude, increases in machine component temperature, and anomalies in acoustic signals are the main factors influencing machine fault detection. Therefore, the proposed system not only improves the accuracy of machine fault diagnosis but also provides transparency in the decision-making process, thereby supporting the implementation of predictive maintenance in smart manufacturing environments.

This study comprehensively evaluates the quality of biomass briquettes produced from blends of coconut shell charcoal and sengon sawdust, using both carbonized and non-carbonized materials. Composite briquettes were fabricated with varying compositions and characterized through proximate analysis, calorific value, density, and burning rate measurements to determine their suitability as solid fuel. The results indicate that adding non-carbonized sawdust increases volatile matter content and burning rate but reduces the calorific value of the briquettes. In contrast, incorporating up to 10% carbonized sawdust significantly improves the calorific value to 6119.2 cal/g, approaching that of pure coconut shell charcoal (6352.2 cal/g), while maintaining a relatively high burning rate. Briquettes containing carbonized sawdust also exhibit low ash content, below 3%, and moisture content under 8%, meeting standard solid fuel quality requirements. These findings demonstrate that a strategic combination of carbonized and non-carbonized materials can produce hybrid biomass briquettes with optimized thermal performance, providing a promising, sustainable, and environmentally friendly alternative fuel for domestic and industrial applications.

Employment agreements are essential legal instruments that regulate the rights and obligations of workers and employers in industrial relations, aiming to ensure legal certainty and balance. In practice, however, the implementation of employment contracts often faces challenges such as differing interpretations, unequal bargaining positions, and inconsistent application of labor regulations. These issues require an effective and constructive dispute resolution mechanism that can address contractual problems while preserving employment relationships. In the Indonesian labor law system, mediation is recognized as a key non-litigation mechanism facilitated by government-appointed mediators to help parties reach mutually acceptable solutions. This study examines the mediation mechanism for resolving employment agreement disputes in Indonesia and analyzes its role as an alternative to court proceedings that emphasizes deliberation, efficiency, and cooperation. Using a normative legal research method with statutory and conceptual approaches, the study analyzes relevant labor laws, mediation regulations, and legal doctrines through a comprehensive literature review. The findings show that mediation is conducted through structured stages, including dispute registration with labor authorities, mediator appointment, facilitated negotiations, and the formulation of agreements or written recommendations. Mediation effectively promotes consensual solutions, reduces procedural complexity, and encourages cooperative communication. It also supports the preservation of harmonious and sustainable employment relationships by prioritizing consensus over adversarial processes. Strengthening mediator competence and improving legal awareness among workers and employers are therefore crucial to optimizing the effectiveness of mediation in resolving employment agreement disputes in Indonesia.

Intensive exploitation of fish for caviar production currently threatens the extinction of sturgeon, one of the ancient fish species. Sturgeon egg harvesting is often carried out in inhumane ways, such as dissecting and killing parent fish, causing the natural sturgeon population to decline. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates the international trade of sturgeon and caviar, but weak law enforcement, high market demand, and widespread illegal trade all exacerbate the conservation status of this species. Conversely, caviar aquaculture, often considered an alternative, raises new bioethical issues, including long-term stress on fish, disease spread, decline in animal health, and the risk of hybridization that could threaten the genetic integrity of sturgeon populations. From a bioethical and environmental ethics perspective, it is difficult to justify the consumption of caviar as a luxury commodity at the expense of ecosystem sustainability and animal welfare. Therefore, sturgeon conservation requires a comprehensive approach that includes reducing consumer demand, improving legislation and enforcement, and preserving and restoring sturgeon's natural habitats.
