Industrial development in Indonesia has significantly contributed to national economic growth; however, it also poses potential risks of environmental pollution when corporate waste management is not conducted properly. Environmental pollution resulting from corporate waste activities may cause harm to surrounding communities, including health problems, ecosystem degradation, as well as material and immaterial losses. In this context, the class action mechanism serves as a relevant legal instrument to collectively advocate for the rights of affected communities. This study aims to analyze the implementation of the class action mechanism in environmental pollution cases based on Decision Number 29/Pdt.G/2023/PN.Skh and to evaluate its effectiveness in providing legal protection and restoring the rights of affected communities. This research employs normative legal research using statute approach, case approach, and conceptual approach. The findings indicate that the class action mechanism in the aforementioned decision fulfilled the requirements of numerosity, commonality, typicality, and adequacy of representation as regulated under Supreme Court Regulation (PERMA) Number 1 of 2002. Procedurally, the class action proved effective in enhancing access to justice, ensuring judicial efficiency, and strengthening the protection of the constitutional right to a good and healthy environment. However, its substantive effectiveness remains dependent on the fulfillment of formal requirements, the quality of evidence presented, and the consistent application of environmental law principles by judges. Therefore, the class action mechanism constitutes an important instrument in environmental law enforcement, yet it requires consistent regulatory support and judicial practice to achieve optimal ecological justice.

Acute Respiratory Infections (ARI) remain one of the public health problems that contribute significantly to high morbidity rates, especially among vulnerable groups. Community health centers, as primary health care facilities, play an important role in recording, reporting, and monitoring cases through surveillance systems. This study aims to determine the description of ARI cases and evaluate the implementation of the ARI surveillance system at the Perumnas Community Health Center from August to October 2025. This study uses a descriptive evaluative approach. The surveillance system evaluation is based on the 5M components, namely man, money, material, method, and machine. Data were obtained through a review of surveillance documents and observation of the implementation of the ARI case recording and reporting system at the health center. The results of the study indicate that ARI is still one of the most common diseases found in the Perumnas Community Health Center's working area. The implementation of ARI surveillance is generally running well, but there are still several obstacles in terms of human resources, supporting facilities, data completeness, and optimization of reporting methods. These conditions affect the quality of the epidemiological information produced. Therefore, it is necessary to strengthen the surveillance system by increasing the capacity of officers, providing supporting facilities, and improving recording and reporting mechanisms so that the implementation of ARI surveillance is more effective and supports disease control efforts.

The doctrine of open legal policy is a jurisprudential construction of the Constitutional Court that provides space for lawmakers to formulate norms as long as they do not contradict the 1945 Constitution of the Republic of Indonesia. Nevertheless, the application of this doctrine in the practice of law testing has raised various constitutional problems, particularly concerning the limits of authority between legislators and the Constitutional Court, as well as the protection of citizens' constitutional rights. This research aims to analyze the concept and construction of open legal policy within the Indonesian constitutional system and to formulate the constitutional limits of its application in Constitutional Court decisions. This research is a normative legal study with an approach based on legislation, a conceptual approach, and a case approach. The legal materials used include the 1945 Constitution, relevant legislation, and pertinent Constitutional Court decisions. The research results indicate that open legal policy cannot be interpreted as absolute freedom for lawmakers, but must be limited by the principle of constitutional supremacy, protection of constitutional rights, and the principle of proportionality as reflected in Article 28J paragraph (2) of the 1945 Constitution. The ambiguity of the parameters for applying this doctrine has the potential to cause inconsistencies in rulings and disrupt legal certainty. Therefore, a more precise and consistent formulation of constitutional limits is necessary to maintain the balance between representative democracy and constitutional oversight.

Social media is one form of technological advancement that has become an integral part of students’ lives, including university students. Its use is not limited to communication and information sharing, but it may also generate psychological effects that influence both physical and mental health. The purpose of this review is to identify and explain the psychological impacts of social media use through appropriate theoretical approaches, which serve as a foundation for discussing the research findings. This study employs a literature review method by examining various academic books and relevant scientific articles. The findings indicate that excessive use of social media has the potential to cause psychological problems among university students, such as social comparison behavior, cyberbullying, decreased sleep quality, and reduced learning productivity. These issues are influenced by several factors, including the intensity of social media use, the type of content accessed, and individuals’ ability to manage emotions and time. Furthermore, uncontrolled social media use may lead to difficulties in social relationships, increased procrastination, poor time management, and reduced self-control in using social networking platforms. Therefore, students are encouraged to develop healthier patterns of social media use to reduce the risk of psychological disturbances. This review is also expected to assist healthcare professionals in understanding the relationship between the intensity of social media use and the occurrence of depressive symptoms among university students.

The increasing use of facial cosmetics among adolescents and young adults is not always accompanied by adequate cosmetic literacy, potentially leading to skin health problems. Many consumers choose products based on trends without understanding their skin type, ingredients, and safety aspects, which can lead to skin barrier damage, irritation, and long-term dermatological disorders. This study aims to analyze the influence of cosmetic choices on facial skin health through a literature review. The method used was a qualitative literature study with a purposive sampling technique of scientific articles published between 2015 and 2025 that were relevant to the behavior of adolescents and young adults and the impact of cosmetic ingredients on the skin. Data were analyzed using content analysis to identify the relationship between knowledge, attitudes, and cosmetic choices. The results show that cosmetic knowledge tends to be high, but is not always followed by appropriate selection behavior, with varying correlation strengths. These findings confirm that cosmetic literacy contributes to the tendency to choose more appropriate products, but is not the sole determining factor. Therefore, education is needed that emphasizes cognitive aspects while fostering critical attitudes in choosing cosmetics safely and responsibly.

The postpartum period is a crucial phase for mothers to recover after childbirth. One of the common problems is perineal wounds, caused either by episiotomy or spontaneous rupture, which require proper care to prevent infection and accelerate healing. This case study aimed to provide midwifery care for Mrs. M, 28 years old, P3A0H3, with a second-degree perineal wound at PMB Bd. Silvi Ayu, S.Keb. The SOAP approach was applied through assessment, diagnosis, intervention, implementation, and evaluation over five days (June 12–16, 2025). Interventions included education on perineal hygiene, encouragement of nutritious food intake, light mobilization, and perineal wound care using boiled binahong leaves. The results showed decreased pain, reduced edema, a dry wound, and complete healing on the fifth day, with the REEDA score decreasing from 11 to 0. The discussion emphasized that flavonoids, saponins, and ascorbic acid in binahong leaves contribute to tissue regeneration and faster healing. Limitations of this study included the short monitoring period, limited sample, and reliance on maternal compliance. In conclusion, binahong leaf decoction was found to be effective, practical, and able to enhance maternal independence in wound care. This study is expected to serve as a reference for midwifery practice and as a basis for further research with a wider scope.

This activity was conducted in Timbang Lawan Village, located in Bahorok Sub-district, Langkat Regency, North Sumatra Province. The results of surveys and interviews with partners indicate that most residents, especially housewives, carry out activities at home, work as agricultural laborers, and engage in farming. This situation provides significant opportunities to train and educate them through programs aimed at improving economic conditions and financial independence. However, the main inhibiting factors identified are limited access to information, knowledge, and technology, which hinder their creativity in utilizing leisure time productively. The purpose of this community empowerment program is to provide education and socialization to inspire and empower the community in addressing economic problems through training in making dishwashing liquid. After this activity, it is expected that participants can reduce household expenses by no longer needing to purchase dishwashing liquid on a daily basis. Moreover, if opportunities arise, they may also identify business prospects to develop dishwashing liquid production. The expected benefit of this activity is to foster an entrepreneurial spirit among housewives in Timbang Lawan Village.

Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

The ability to read the Qur’an is a fundamental competence that must be possessed by every Muslim student. However, in educational practice at schools, various problems are still found, particularly the low level of Qur’an reading ability among some students, accompanied by learning boredom. One of the contributing factors to this condition is the use of a single, monotonous, and less varied teaching method. This article aims to examine the problems related to students’ ability to read the Qur’an and the learning boredom that arises due to the implementation of a single method in instruction, as well as to offer practical solutions that can be implemented by educators. The writing method of this article uses a literature review approach and reflection on teaching practice. The results of the study show that a single teaching method tends to reduce students’ learning motivation, hinder active engagement, and slow down the improvement of Qur’an reading skills. Therefore, it is necessary to implement more varied, interactive, and contextual teaching methods, such as game-based learning, group work, and the use of innovative instructional media. Thus, it is expected that students’ ability to read the Qur’an can improve and learning boredom can be effectively minimized.
