This study aims to address the challenges and propose solutions for the Optimization of Blockchain-Based Cybersecurity Systems to Enhance Resilience Against Ransomware Attacks using a Systematic Literature Review (SLR) approach. Blockchain is increasingly recognized as a transformative technology in cybersecurity due to its decentralized structure, transparency, and robustness in securing data. Despite these advantages, its widespread adoption is hindered by several challenges, including scalability, interoperability, high energy consumption, and limited access to representative ransomware datasets. This research highlights that integrating blockchain with advanced technologies such as data analytics, machine learning, and Explainable AI (XAI) can significantly enhance its effectiveness in combating ransomware.The findings reveal that Graph Convolutional Neural Networks (GCN) enable real-time detection of ransomware patterns in network traffic with an accuracy of up to 95%. Furthermore, Layer-2 solutions like the Lightning Network and sharding effectively alleviate the load on main blockchains, thereby increasing transaction throughput. Efficient consensus mechanisms, including Proof of Stake (PoS) and Delegated Proof of Stake (DPoS), address energy consumption issues, making blockchain more adaptable to IoT and resource-constrained environments. These approaches have proven successful in enabling early detection, mitigation, and prevention of ransomware in IoT systems, cloud infrastructures, and smart grid networks. The implications of this study underscore the potential of blockchain as a critical component of proactive and adaptive cybersecurity systems. However, overcoming existing challenges requires further development of hybrid frameworks that integrate blockchain with data analytics and machine learning technologies. In addition, efforts should focus on standardizing global security protocols to enhance interoperability and creating robust, diverse ransomware datasets to support more accurate detection systems. Future research should also explore methods to minimize latency and improve blockchain efficiency in real-time cybersecurity applications.

This research aims to explain the management control of public street lighting (PJU) in Tanjungpinang City. PJU is an important element in creating safety and comfort for the community in economic, social and traffic activities. However, not all areas in Tanjungpinang have been covered by PJU facilities, and many PJUs are damaged. This research uses the control theory by T. Hani Handoko (2010) which consists of 1) Feedforward control, 2) Concurrent control, and 3) Feedback control. The research method used is qualitative with data collection techniques of observation, interview, and documentation. The results showed that PJU management control in Tanjungpinang City was not optimal. In feedforward control, there are obstacles such as the lack of community participation in PJU development planning. In concurrent control, coordination between the community, the Housing, Settlement Areas, Cleanliness and Parks Office, consultants, PLN, and contractors has not been optimal. While in feedback control, the lack of community participation in reporting damage and maintenance of PJU is only done based on reports or surveys with priority on protocol roads. Routine supervision is limited due to limited human resources, and response to public complaints is slow. This study concludes that the improvement of PJU management requires good planning and active community participation.

Traditional marriage in Pulau Buaya Village is not just the union of two individuals, but also a bond between two large families that involves social, cultural, and economic aspects. The traditional marriage customs in this village have significant stages that reflect the values of collectivism and respect for ancestors. However, the majority of the community also adheres to Islam, which has its own legal rules regarding marriage. The interaction between customary law and Islamic law in marriage practices often results in adaptations or acculturation that do not always proceed smoothly. Some traditional customs sometimes conflict with the principles of Islamic law, creating challenges in balancing the preservation of traditions with adherence to religious teachings. This study uses a juridical-empirical method with a qualitative approach. Primary data is obtained through interviews and direct observation of traditional leaders, religious leaders, and couples who have undergone traditional marriages. Secondary data is gathered from literature studies on customary law and Islamic law. The findings show that the customary marriage law in Pulau Buaya Village has been adjusted to Islamic principles, but practices still exist that contradict Islamic law. The implications of this study are the need for an integrative approach in formulating marriage policies that respect cultural diversity while remaining in accordance with Islamic and national legal principles.
