Purpose: This study investigates the criteria and indicators essential for determining the efficiency of small industrial enterprises, a sector crucial for sustainable economic development yet often underserved by traditional evaluation frameworks. Research methodology: The research draws on existing synergistic efficiency frameworks, particularly those developed by Kondratiev et al. (2022), and integrates insights from production capacity modeling to propose a refined system of indicators suitable for small enterprises. Utilizing a mixed-method approach combining economic-mathematical modeling, statistical analysis, and case study evaluation, the study examines fluctuations in equipment utilization, labor productivity, and material efficiency over a thirty-year period. Results: Results indicate that while material efficiency remains relatively stable, labor and equipment productivity are highly variable, reflecting inconsistencies in workforce management and capital utilization. These findings underscore the limitations of conventional metrics and the need for multidimensional models that incorporate internal and external performance drivers. Contribution: This research contributes to the academic discourse by filling a gap in performance evaluation literature for small-scale industry and offers a foundation for future work in developing sector-specific benchmarking systems, performance dashboards, and policy instruments to support sustainable industrial growth. Implication: The implications are significant: small enterprises require adaptive, real-time efficiency monitoring tools that are both theoretically sound and practically implementable.

Purpose: This study aimed to analyze the impact of the Hasanudin-Petrosea road infrastructure improvement on the economic activities of surrounding communities in Mimika Regency, focusing on production, distribution, and income levels. Research/methodology: Using a quantitative descriptive approach, primary data were gathered through field observations, structured questionnaires, and documentation. Respondents were selected using purposive sampling, and data were analyzed using descriptive statistical methods to identify changes in economic activities before and after the infrastructure development. Results: The findings indicate a significant positive impact on the local economy of the area. Most respondents reported increased production capacity, smoother distribution processes, and higher income levels following road improvements. Improved accessibility has stimulated the growth of small businesses, such as workshops, food stalls, and kiosks, along the upgraded road segment. Conclusions: The improvement of Hasanudin–Petrosea Road infrastructure has positively influenced local economic activities by enhancing production efficiency, supporting the distribution of goods, and increasing the household income. It has also encouraged the development of small businesses along the corridor. To sustain these benefits, continuous infrastructure maintenance and integrated economic planning are necessary to ensure the long-term prosperity of local communities. Limitations: This study was limited to one geographic location and a relatively small sample size, which may not fully reflect the broader regional impact. The analysis also does not address the long-term sustainability or maintenance aspects. Contribution: This study adds to the literature on infrastructure-led local economic development by providing empirical evidence on how improved road access stimulates production, distribution efficiency, and income while serving as a policy reference for future infrastructure planning in underdeveloped regions.

Purpose: This study aims to evaluate the potential and effectiveness of central market retribution revenue and its contribution to the Regional Original Income (PAD) of Mimika Regency. It seeks to determine whether retribution is managed optimally and whether it provides meaningful income to the local government. Research/methodology: A quantitative approach with descriptive and case study methods was used. Data were collected through documentation, questionnaires, and interviews between 2019 and 2023. The analysis used the effectiveness ratio, contribution analysis, and potential calculation with standard regional financial formulas. Data validation was ensured using triangulation techniques. Results: The findings revealed that the effectiveness of the central market retribution collection in Mimika remained high, with an average rate above 90% categorized as effective. However, its contribution to PAD was consistently low, averaging only 2.03% from 2019 to 2023. The study also found that retribution potential was not fully realized due to limited trader registration, low payment compliance, and reliance on manual tax collection systems. Conclusions: Retribution collection was consistently effective, but its contribution to PAD was minimal. This gap is mainly caused by unregistered traders, poor compliance, and inefficient manual record-keeping systems. To maximize revenue, the government must strengthen data management and monitoring and adopt digital retribution mechanisms. Limitations: This study is limited to one market (Pasar Sentral Timika) and relies primarily on secondary data, which may not capture real-time inefficiencies or informal economic activities. Contribution: This research contributes to the fiscal policy literature by highlighting the gap between potential and actual retribution performance and offering recommendations for improved revenue collection through digitization, trader data management, and regulatory enforcement.
