Improving the quality of Human Resources (HR) is a major challenge in facing global competition. Education as the main means of improving the quality of HR in Indonesia is still faced with the problem of inequality of access and quality between regions. This inequality causes disparities in educational development between urban and remote areas. This study focuses on grouping provinces in Indonesia based on aspects of educational development in 2023, using cluster analysis. Secondary data from the Central Statistics Agency (BPS) is used as the basis for analysis, including variables of average length of schooling, Gross Participation Rate (APK), Pure Participation Rate (APM), number of senior high schools, and community literacy development index. This study uses hierarchical and non-hierarchical cluster analysis methods to group provinces in Indonesia. The results of the hierarchical cluster analysis using the average linkage method show the most optimal cluster with the formation of three clusters. The first cluster consists of 31 provinces, the second cluster consists of 2 provinces, and the third cluster consists of 1 province. Data characteristics show large variations in the number of senior high schools and relative homogeneity in the average length of schooling between provinces.

Customary law reform in Indonesia in the context of globalization raises significant challenges and opportunities. The values of Pancasila, as the ideological foundation of the nation, play an important role in ensuring that customary law reform remains relevant, fair and rooted in local culture. Globalization encourages the modernization and homogenization of the legal system, which often contradicts the principles of customary law based on local wisdom. This article examines how Pancasila values, such as humanity, social justice, unity, and deliberation, can be integrated in the process of customary law reform to remain relevant amid global dynamics. This research uses a qualitative approach with the methods of literature study, interviews, and document analysis. Literature study was conducted to understand the theoretical context of customary law reform and Pancasila values, while interviews were conducted with legal experts, academics, and traditional leaders to obtain empirical perspectives on challenges and opportunities in customary law reform. Document analysis was conducted on policies and regulations relating to customary law and the implementation of Pancasila values in Indonesia. The results show that customary law reform based on Pancasila has great potential to deliver a legal system that is more inclusive and responsive to the needs of local communities. Key challenges identified include difficulties in harmonizing customary law with national and international law and homogenizing pressures from global standards. However, opportunities are also found in the ability of updated customary law to provide more culturally and locally relevant dispute resolution alternatives. The integration of Pancasila values is believed to strengthen the position of customary law within national and global legal frameworks.ract

Violence against women remains a serious issue in Indonesia despite the existence of Law Number 23 of 2004 on the Elimination of Domestic Violence (KDRT). This study aims to evaluate the effectiveness of the implementation of this law in reducing violence against women and to identify the barriers in its implementation. The research method used is a normative legal approach, focusing on the analysis of relevant regulations and related policies. The findings show that although legal awareness has increased, many women victims of violence are still hindered by social and cultural factors in reporting the incidents. Institutional factors, such as limited resources in law enforcement agencies, also affect the effectiveness of protection. The implication of this research is the importance of a thorough evaluation of existing policies and the need to improve the capacity of law enforcement agencies to handle cases of violence against women more effectively.

Drainage is an infrastructure system designed to channel water from one place to another. This study is based on Article 2 of the Regulation of the Minister of Public Works of the Republic of Indonesia No. 12 of 2014 concerning the Implementation of Urban Drainage Systems. This research aims to analyze the drainage maintenance carried out by the Public Works and Housing Office (PUPR) of Pekanbaru City using Dhillon B.S’s asset maintenance theory, which consists of two main indicators: preventive maintenance and corrective maintenance. This study employs a qualitative approach with data collection methods including in-depth interviews and field observations. The results indicate that drainage maintenance in Pekanbaru City faces several challenges, such as budget constraints, low public awareness, a shortage of skilled labor, outdated infrastructure conditions, and the impact of extreme weather conditions. The findings suggest that the drainage maintenance efforts by the PUPR Office of Pekanbaru City still encounter numerous challenges, particularly in technical aspects and community participation. Therefore, it is necessary to increase the budget and develop more competent human resources in the field of drainage maintenance.
