The practice of fishing using bombs (blast fishing) presents a serious threat to marine ecosystems and the sustainability of coastal communities' livelihoods. Law enforcement against these violations faces complex challenges, especially in large areas of water with limited fleet and patrol personnel. Perpetrators who move quickly and change locations, coupled with the lack of reports from the public due to fear or social ties, further complicate enforcement efforts. In addition, access to hidden locations and coordination between law enforcement agencies that are not optimal are also the main obstacles. Global studies confirm that the lack of effective law enforcement and adequate governance is a significant driver of these destructive practices, even beyond socio-economic factors. Therefore, a comprehensive strategy is needed that includes strengthening integrated marine patrols on a regular basis, imposing strict sanctions, increasing socialization of the dangers of fish bombs, and the active involvement of coastal communities as supervisors. A synergistic approach between law enforcement officials and local communities, combining prevention and joint management measures, is key to achieving effective marine conservation and sustainable management of fishery resources.

Drug abuse (Narcotics, Psychotropics, and other Addictive Substances) is a serious problem that can threaten the younger generation, especially in the Panggung Kidul Village area. The lack of public understanding, especially teenagers, regarding the dangers and negative impacts of drug abuse is one of the factors that influence the high risk of substance abuse. Therefore, innovative and interactive educational media are needed to increase public awareness and understanding regarding the prevention of drug abuse. This study offers a solution by designing and developing educational media based on Augmented Reality (AR) technology as a visual and interactive tool that conveys information in an interesting and easy-to-understand manner. The use of smartphones as the main device in AR applications makes this media more easily accessible to various groups of people. The test results using the System Usability Scale (SUS) method showed a user satisfaction level of 96% which is included in the Acceptable category. Thus, this AR-based educational media is expected to be an effective means of increasing public understanding of the dangers of drug abuse and encouraging early preventive efforts.

Diabetes mellitus (DM) is a metabolic disease characterized by elevated blood glucose levels. This condition includes several types, such as type 1 and type 2 diabetes. It occurs when the body is unable to produce enough insulin, experiences impaired insulin function, or faces a combination of both. As a result, glucose cannot be effectively absorbed by the body’s cells and accumulates in the bloodstream, leading to high blood sugar or hyperglycemia. If this condition persists, the buildup of glucose can cause various disorders in different organs. Without proper management, diabetes may lead to severe and life-threatening complications. Chronic hyperglycemia in diabetic patients is associated with long-term damage, dysfunction, and even failure of vital organs such as the eyes, kidneys, nerves, heart, and blood vessels. In this activity, percentage-based methods and demonstrations of blood glucose testing were used as educational tools for students. The results showed that students’ awareness of the dangers of elevated blood sugar levels remains low. Many of them are still unfamiliar with the importance of regular blood glucose monitoring and maintaining a healthy lifestyle to prevent diabetes. Therefore, continuous efforts are needed to provide education and outreach on the prevention and early management of diabetes mellitus.

The results of the activity show that children better understand the importance of critical thinking when getting information. This activity is expected to increase knowledge about digital literacy and encourage smart media behavior.

This article discusses the modernity of educational instruments, along with the phenomenon of technological progress, particularly the emergence of artificial intelligence (AI), and its implications for educators in the 21st century. Rapid advances in AI have led to fundamental shifts in teaching strategies and resources, shifting from traditional models to personalized and adaptive learning environments. Through automated assessments, curriculum customization, and the implementation of virtual assistants that enhance accessibility, artificial intelligence (AI) in education aims to improve efficiency and effectiveness. However, this modernity requires educators in the 21st century to change. Teachers now play the role of facilitators, designers of learning experiences, and mentors in ethics, in addition to being providers of knowledge. Teachers need to master AI literacy and focus on teaching students the four Cs of the 21st century: communication, creativity, critical thinking, and teamwork. The integration of AI raises ethical issues related to data privacy, the digital divide, and the dangers of plagiarism, but it also offers significant potential. Therefore, the effective integration of AI technology with irreplaceable human qualities is crucial for the success of contemporary educational technology. AI is an important tool for educators in the 21st century to develop a generation of technologically literate and moral individuals.

Smoking behavior among adolescents in Indonesia remains a serious public health challenge with increasing prevalence. Adolescence is a vulnerable period where psychological factors and the social environment significantly influence the decision to smoke. This study aims to review the factors influencing smoking behavior among adolescents based on the Health Belief Model (HBM) theoretical framework. This study is a literature review that analyzes various research findings related to the determinants of smoking behavior using HBM components. The analysis shows that all dimensions of HBM play a role in shaping smoking behavior. Self-efficacy and perceived susceptibility were found to be the strongest predictors. Although adolescents have a good perceived severity of the dangers of smoking, they are often hindered by high perceived barriers, such as peer pressure and psychological dependence. Consistent cues to action and perceived benefits are proven to encourage prevention and smoking cessation efforts. Adolescent smoking behavior is strongly influenced by individual beliefs in self-ability and health risks. Health interventions should focus on strengthening self-control and managing social influences to reduce the number of adolescent smokers.

This article, titled "Parental Participation and Preventive Measures Against Cigarette Smoke Exposure in Early Childhood," aims to describe the impact of cigarette smoke exposure on the health of early childhood and analyze the role of parents in prevention efforts. This research used a literature review method, compiling data from books, journals, research reports, and related academic sources. The results of the study indicate that cigarette smoke exposure can increase the risk of respiratory disorders, reduce immunity, exacerbate asthma, and trigger various chronic diseases in children. These findings confirm that early childhood is the group most vulnerable to the dangers of cigarette smoke, both from active and passive smoking. Furthermore, the discussion demonstrates the central role of parental participation through smoking cessation, the implementation of smoke-free homes, maintaining a clean environment, and ongoing family education. Various strategies, such as evidence-based education and the use of digital media, are also considered effective in raising parental awareness. Therefore, protecting children from cigarette smoke exposure requires family commitment and the support of a healthy environment.

This community service activity was carried out to increase students' understanding of the dangers of drug abuse and its impact on academic achievement and the future of the younger generation at SMK Negeri 1 Pagelaran.

This study examines in depth the concepts of maysir, gharar, and riba as three practices that are prohibited in sharia economics because they are considered to cause injustice and imbalance in economic activities. Through an analysis of the postulates of the Qur'an and Hadith, this study confirms that the prohibition of maysir is based on the element of excessive speculation that harms one of the parties, gharar is rejected because it contains ambiguity in the object and contract, while riba is prohibited because it creates an unequal addition in financial transactions. In addition, the study highlights how other religions and various modern economic systems have paid attention to the principles that are in line with the prohibition of these three concepts, especially related to business ethics, social justice, and economic risk mitigation. A cross-faith perspective shows that universal values such as honesty, transparency, and balance are essential foundations for building a sustainable economic order. By combining normative perspectives and cross-tradition comparisons, this study seeks to provide a comprehensive understanding of the dangers of maysir, gharar, and usury, as well as the implications of the implementation of their prohibition in modern economic life. The results of the study are expected to be a reference in formulating economic practices that are fair, stable, and able to be widely applied in various communities.

The Community Service Program (KKN) is a form of student community service aimed at helping resolve social problems. This research focuses on publicizing the dangers of online gambling (judol), a global phenomenon that causes moral, economic, and social harm, by integrating it with Sharia principles in Perkebunan Gunung Melayu Village. The method used was Participatory Action Research (PAR) with a qualitative approach. The 13-day program involved initial observation, educational-participatory socialization interventions that emphasized the prohibition of Maisir and its relationship to Maqāṣid al-Sharīʿah (Objectives of Sharia), and impact evaluation. The implementation results demonstrated high community enthusiasm and a significant increase in cognitive awareness and understanding of Sharia as a spiritual bulwark against online gambling practices. Furthermore, supporting activities such as mutual cooperation (gotong royong) successfully revitalized the spirit of collaboration and social participation. Despite time constraints and weather constraints, the entire KKN program successfully had a transformative impact, strengthening the community's religious and social values. This study recommends the need for continued monitoring and mentoring to ensure the sustainability of the awareness that has been formed.
