Air quality in the Special Capital Region of Jakarta has shown a concerning decline in recent years, largely due to high emissions from motor vehicles as the main source of pollution in urban areas. The Provincial Government of DKI Jakarta issued Governor Regulation Number 66 of 2020 concerning Exhaust Emission Testing for Motor Vehicles as a public policy instrument aimed at controlling air pollution. This study aims to analyze the implementation of the regulation from a public policy perspective and to identify supporting and inhibiting factors in its execution. The research employs a normative juridical method with statutory and conceptual approaches, supported by qualitative analysis of policy documents and reports on the implementation of emission testing. The results reveal that the implementation of the regulation has not been optimal due to limited emission testing infrastructure, low levels of public awareness and socialization, and inconsistent enforcement of administrative sanctions. Nevertheless, there are opportunities to improve policy effectiveness through strengthened inter-agency coordination, digitalization of monitoring systems, and increased environmental literacy among the public. Therefore, the success of emission control policy implementation is highly dependent on resource support, regulatory consistency, and community awareness, necessitating a comprehensive and continuous multi-stakeholder improvement strategy and stronger commitment.

This study was conducted at PT. Asmin Bara Bronang, Sepan Uring Village, Kapuas Tengah District, Kapuas Regency, Central Kalimantan Province, with the aim of analyzing the productivity and influencing factors of the PC 300 excavator in coal getting activities to support the achievement of production targets. The objective of this research is to analyze the actual productivity and the factors affecting it in Sector 7 coal getting operations. The research method used field observation with a quantitative descriptive analysis approach. The results show that the productivity of the PC 300 excavator ranges from 127.12 to 224.29 tons/hour, with an average of 173.98 tons/hour. In several conditions, the productivity is still below the company’s target of 180 tons/hour. The analysis indicates that productivity is influenced by material conditions, particularly the Hardgrove Grindability Index (HGI) value of 47, which reflects relatively harder material with coarser particle size, and a moisture content of 22.71%, causing the material to be sticky and cohesive, thereby affecting the bucket filling process. In addition, operational factors such as bottom loading patterns, limited number of tailgate dump trucks, and suboptimal selection of dump truck types also contribute to productivity performance.  Based on the findings, it can be concluded that the productivity of the PC 300 excavator has not consistently met the company’s target. Therefore, improvement efforts are required, including the implementation of top loading methods, increasing the number of tailgate dump trucks, optimizing the selection of hauling equipment, and controlling material conditions that affect the digging process.

The issue of illegal parking in the Pasar Jambi area remains unresolved despite various enforcement efforts carried out by the Jambi City Transportation Agency. Non-compliant parking practices, such as the presence of unauthorized parking attendants, the imposition of fees beyond official rates, and the lack of use of official attributes, indicate a discrepancy between established standards and actual field conditions. This study aims to analyze the effectiveness of the Transportation Agency’s supervision in controlling illegal parking in the Pasar Jambi area by applying George R. Terry’s supervision theory indicators. The research employs a qualitative method with a case study approach, using data collection techniques including observation, interviews, and documentation. The findings reveal that supervision has been implemented through stages of setting standards, measuring performance, comparing implementation with standards, and taking corrective actions. However, the effectiveness of supervision is still not optimal. This is reflected in the persistent gap between standards and practices in the field, the limited number of supervisory personnel, and corrective actions that have not been consistently effective in creating a deterrent effect. Although enforcement has been carried out progressively through warnings, guidance, and direct actions, violations continue to occur repeatedly. The implications of this study highlight the need to strengthen consistency in supervision, enforce stricter sanctions, and enhance resource capacity so that supervision is not merely administrative but can create sustainable parking order.

Dengue fever is a disease commonly found in tropical and subtropical regions. This disease can cause severe symptoms, such as very high fever, accompanied by nausea, vomiting, headache, abdominal pain, and leukopenia (decrease in white blood cells). This infectious disease, known as dengue hemorrhagic fever (DHF), is a viral infection transmitted by the Aedes Aegyppti mosquito. This study aims to classify dengue-prone areas using the K-Means Algorithm, and to classify the factors that cause dengue in Purwodadi District, Grobogan Regency. The clustering results using the K-Means algorithm with Rapidminer tool from 266 data produced 3 clusters: cluster 0 (blue) with 138 patients dominated by Kuripan, Purwodadi, Ngambak villages, cluster 1 (green) with 31 patients in Ngraji, Nambuhan, Cingkrong villages, and cluster 2 (orange) with 97 patients in Danyang, Kalongan, Pulorejo villages. This study is expected to provide additional information for stakeholders in controlling dengue cases and increase awareness of the importance of environmental cleanliness as a preventive measure.

Bullying in the school environment is a social health problem that has a massive impact on children’s physical, mental, and social well-being. As the primary educational environment, schools need to implement a structured, safe, and child-friendly bullying reporting system. Objective: This conceptual study aims to design the implementation of a bullying reporting system based on school health administration using the functional management approach: planning, organizing, actuating, and controlling (POAC). The methods and components of the reporting system are designed through the four POAC pillars, namely the establishment of an Anti-Bullying Team, the preparation of Standard Operating Procedures (SOPs), the provision of child-friendly reporting media both physical and digital through the School Health Unit (UKS), and the development of monitoring and evaluation mechanisms (controlling). School health administration is used as an initial screening tool to identify indications of victim trauma discreetly and safely. The implementation of this POAC-based system is expected to improve the early detection of bullying cases, accelerate case handling responses, and eliminate stigma and fear of reporting among children. Conclusion: The integration of health administration and POAC management has proven to be a strong framework for creating a safe, inclusive school environment that strongly supports students’ mental health recovery.

Tourism regulations play a critical role in shaping destination competitiveness and influencing tourist travel decisions, yet empirical evidence on their effectiveness across different institutional contexts remains limited. This study investigates the impact of tourism regulations on tourist visit performance through a comparative quantitative analysis of Indonesia and Singapore. Using panel data covering the period 2010–2023, this research employs a fixed-effects regression model to examine the relationship between regulatory quality and tourist arrivals, while controlling for economic conditions and transport infrastructure. The findings reveal that tourism regulations have a positive and statistically significant effect on tourist visit performance in both countries. However, the magnitude of the effect is substantially stronger in Singapore, indicating higher regulatory efficiency and institutional effectiveness in translating policy interventions into tourism demand. These results support institutional and tourism demand theories, emphasizing that regulatory quality, rather than regulatory volume, is a key determinant of tourism performance. The study contributes to the tourism policy literature by providing cross-national empirical evidence on regulatory impacts and highlighting the importance of governance capacity in tourism development. From a policy perspective, the findings suggest that countries should prioritize regulatory coherence, administrative efficiency, and adaptive governance to enhance tourism competitiveness and resilience.
