This research examines the influence of transactional leadership and the entrepreneurial competence of school principals on the effectiveness of education financing in primary and secondary education settings. Effective education financing is essential to ensure that limited resources are allocated optimally to improve learning quality, infrastructure, and institutional sustainability. Transactional leadership—marked by clear performance standards, reward and punishment mechanisms, and strict supervision—provides a structured framework for financial accountability and goal achievement. Entrepreneurial competence, on the other hand, equips principals with the ability to recognize funding opportunities, innovate in revenue generation, and manage financial risks. The study adopts a quantitative survey design involving school principals and financial management personnel from a representative sample of public and private schools. Data were collected using validated questionnaires and analyzed through multiple regression to measure the direct and combined effects of the two independent variables on education financing effectiveness. The findings reveal that both transactional leadership and entrepreneurial competence significantly and positively affect financial effectiveness. Transactional leadership strengthens transparency and budget discipline, while entrepreneurial competence fosters diversification of funding sources and innovative financial strategies. These results highlight the strategic importance of integrating leadership development with entrepreneurial training for school principals. Strengthening these competencies not only enhances financial planning and accountability but also reduces dependence on a single funding source, supporting long-term educational sustainability. Future studies are encouraged to explore additional mediating factors such as organizational culture, technological infrastructure, and community involvement to provide a more comprehensive understanding of education financing dynamics.

This study aims to analyze the influence of internal audit quality on the effectiveness of hedging policies in energy sector companies listed on the Indonesia Stock Exchange in 2020-2023. Using annual financial statements and annual reports, this study selected 30 companies using a purposive sampling method. The internal audit variable in this study was measured by three proxies: Internal Audit Charter, Internal Auditor Competence, and Internal Auditor Training. This study used multiple linear regression analysis as a hypothesis testing method. The results indicate that Internal Audit Charter Disclosure has a positive effect on hedging effectiveness disclosure, while Internal Auditor Competence Disclosure and Internal Auditor Training have insignificant and negative effects on hedging policy effectiveness. Based on these results, companies with robust internal audit charters and comprehensive components tend to be more proactive in disclosing hedging policies to avoid reputational or regulatory risks. Companies that disclose internal auditor competency and training through documents do not necessarily guarantee disclosure of hedging effectiveness. This indicates that documentation of internal auditor competency or training in annual reports does not necessarily reflect the overall company oversight.

The Terminal Loading Area (TLA) API at PT Pertamina Hulu Mahakam functions as a facility for processing oily water before being discharged into the environment. One of the main issues faced is the accumulation of thick floc (oil clumps) due to high emulsions in crude oil, along with the malfunctioning water spray valve on line 1, causing operators to resort to manual spraying using hydrant water. This increases the risk of exposure to hazardous chemicals such as Benzene, Toluene, and Xylene (BTX), which poses a health threat to workers. Therefore, improvements to the water spray system are needed to reduce BTX exposure and enhance the effectiveness of oil-water separation. This study aims to analyze the effectiveness of proposed improvements to the water spray system to reduce BTX exposure and improve the efficiency of oil-water separation. The methodology used includes literature review, field study, and technical testing. Proposed solutions include replacing or repairing the damaged water spray valve, adding piping networks to compartment 2 to distribute water more evenly, and using treated water (produced water) to optimize the system and reduce reliance on hydrant water. The results of the study indicate that replacing or repairing the water spray valve, adding piping networks, and using produced water effectively reduce BTX exposure while maintaining oil recovery effectiveness. The trials also showed that using the Oil Pump (P-3230 & P-3235) provides optimal pressure (8–9 barg) for water spray, compared to the less effective Water Pump (P-3200 & P-3205). Implementing these solutions is expected to reduce BTX exposure for workers, improve oil-water separation efficiency, and contribute to a safer and more efficient working environment.

Examinations in radiology installations have increased annually, resulting in a higher risk of radiation hazards to staff, particularly in interventional, conventional X-ray, and CT-Scan environments. Furthermore, not all hospitals are equipped with radiation survey meter monitoring devices. Therefore, an innovative radiation exposure monitoring system based on the Internet of Things (IoT) was developed. This study aims to: (1) develop an IoT-based radiation exposure monitoring system, (2) evaluate the device’s performance, and (3) assess the effectiveness of the system. The research method used was research and development (R&D), which included preliminary information gathering, product planning and development, expert validation, device performance testing, effectiveness testing, and final outcomes. This system was developed for real-time radiation dose monitoring.  The product development involved a Geiger-Muller M4011, an ESP32 microcontroller, and a Node-Red web application. Performance testing of the IoT-based radiation exposure monitoring device and a standard survey meter in CT-Scan and conventional X-ray rooms used the T-Test and Mann-Whitney tests. The results showed p-values > 0.05, indicating no significant difference between the two devices. Effectiveness testing through pre-test and post-test questionnaires demonstrated improved usability—namely flexibility, operability, learnability, and understandability—with an N-Gain value of 78.95%, indicating effectiveness. In conclusion, the IoT-based radiation exposure monitoring system proved effective and feasible for real-time radiation dose monitoring in radiology installations, offering advantages in IoT-based data integration, ease of access, and structured data recording. In addition to performance testing, the system was evaluated in terms of its integration with hospital infrastructure. It was designed to provide real-time radiation dose monitoring, automatically updating the dose data and sending alerts when safe exposure levels are exceeded. The system also enables remote monitoring, making it easier for radiology departments to oversee radiation safety without the need for direct physical checks.

The results obtained from the tests indicate that leg muscle explosive power contributed 12.40% to the soccer shooting performance of the players, with the remaining 87.60% influenced by other factors such as technical skill, tactical awareness, and mental readiness. Additionally, foot-eye coordination accounted for 2.70% of the variation in shooting ability, suggesting that while important, it is not the dominant factor in determining shooting success. The remaining 97.30% of the variation could be attributed to other physical, technical, or psychological factors.

The Public-Private Partnership (PPP) scheme with guarantees from PT PII aims to accelerate infrastructure development through private participation, but faces legal and practical challenges, particularly related to the risk of default by the Government and Construction Service Provider (GCA) and the effectiveness of the implementation of recourse rights by PT PII towards government institutions. This study uses a normative juridical method with an analytical descriptive approach through a literature study of primary and secondary legal materials, as well as a qualitative analysis of legal documents, to understand in depth the application of recourse rights to GCA in the PPP mechanism. The application of recourse rights by PT PII as a PPP project guarantor is based on a special legal framework and complex contractual agreements to protect investors from the risk of default by the GCA. However, its implementation has the potential to face legal, political, bureaucratic, and fiscal challenges that can affect the effectiveness of protection and the fiscal sustainability of PT PII. PT PII's recourse rights in the PPP scheme are an adaptation of the borgtocht concept applied lex specialis through the PPP agreement, guarantees, and recourse to protect state finances. However, its implementation faces bureaucratic, budgetary, and fiscal constraints that can hamper its effectiveness. Therefore, binding guidelines and increased institutional capacity are needed to ensure that regress rights can be exercised effectively, accountably, and in accordance with the principles of transparency and accountability. This study concludes that to increase the effectiveness of the PPP scheme, improvements in the legal framework, inter-agency coordination, and strengthening the capacity of institutions involved in implementing regress rights are needed.
