Cigarette smoke is a major source of free radicals that can cause various health problems, including disturbances in the male reproductive system. Nicotine and other harmful compounds in cigarettes increase oxidative stress and interfere with spermatogenesis. Gotu Kola (Centella asiatica) is a medicinal plant known for its antioxidant properties that may help neutralize free radicals. This study aimed to determine the effect of Gotu Kola leaf extract on the histopathological features of the testes in male Wistar rats exposed to cigarette smoke. An experimental study using a Post-Test Only Control Group Design was conducted on 24 rats divided into six groups: a normal group, a negative control group exposed to cigarette smoke, a positive control group treated with vitamin E, and three treatment groups receiving Gotu Kola extract at doses of 120, 180, and 240 mg/kg body weight for 28 days. The observed parameters were Leydig cell count and seminiferous tubule diameter. One-way ANOVA analysis showed that Gotu Kola extract significantly increased Leydig cell numbers and seminiferous tubule diameter in all treatment groups compared to the negative control group (p < 0.05). Post hoc analysis demonstrated significant differences in tubule diameter, with the highest improvement observed at the 240 mg/kg body weight dose. These findings indicate that Gotu Kola extract has potential protective effects against testicular damage caused by cigarette smoke exposure.

The academic transition phase among tenth-grade students represents an important period that requires the ability to adjust to changes in the environment, academic demands, and increasingly complex social dynamics. This study aims to analyze psychosocial dynamics in the student adaptation process during the academic transition phase through a literature review approach. The method employed was a library research study by examining various relevant scientific sources related to adolescent psychosocial development, adaptation processes, psychosocial impacts, and strategies for addressing students’ adaptation problems. The results of the review indicate that the adaptation process is influenced by both internal and external factors. Internal factors include emotional condition, coping ability, and self-control, while external factors include support from family, peers, teachers, and the school environment. Students’ inability to adapt may lead to anxiety, low self-confidence, academic difficulties, and obstacles in social interaction. Efforts to support students’ adaptation process can be carried out through strengthening social support, optimizing guidance and counseling services, and implementing self-management techniques to enhance students’ self-regulation abilities. With appropriate support and intervention strategies, students are expected to navigate the academic transition phase more effectively and develop optimally in psychological, social, and academic aspects.

Hypertension in pregnant women and Women of Reproductive Age remains a significant health problem in West Java Province. The prevalence of hypertension among pregnant women in West Java is approximately 10.57%, higher than the national rate of 6.18%, while the prevalence among WRA ranges from 25% to 30%.

Dijkstra's algorithm is one of the algorithms in graph theory that is used to solve the problem of the shortest path of a graph at each vertex that has a non-negative value. This algorithm was discovered by Edsger Wybe Dijkstra, a scientist from the Netherlands. The search for the shortest route for product delivery can be calculated through the application of the Dijkstra algorithm in the problem being faced. The problem of decision making for selecting the shortest route is still manual, so it experiences several obstacles, including the absence of a systematic and computerized system to assist the decision-making process in determining the route for shipping goods, the determination of shipping routes still depends on manual estimates so that the time taken between deliveries becomes inconsistent, the operational costs of shipping are relatively high because there is no optimal route determination system. Facing these problems, a system is needed that can minimize delays and increase effectiveness in shipping goods, namely determining the shortest route using the Dijkstra algorithm. This system works by finding various alternative routes for shipping goods at PT AMSA to address various structured and unstructured problems using data and models. To process this data and models, a method called the Dijkstra algorithm is required. Based on the description above, researchers will create a method for determining the shortest route for shipping goods at PT AMSA using the Dijkstra algorithm to facilitate the company's process of determining the shortest route.

The increasing complexity of urban transportation systems demands intelligent and measurable navigation methods. Medan City, the capital of North Sumatra Province, has a dense road network with multiple route options that often confuse road users. Dijkstra's Algorithm, developed by Edsger Wybe Dijkstra in 1959, is a greedy-based computational approach proven effective for solving the shortest path problem on non-negative weighted graphs. This study applies Dijkstra's Algorithm to determine the shortest route from Medan Railway Station to Universitas Negeri Medan (UNIMED). The road network was modeled as an undirected weighted graph with 15 nodes and 16 edges, where edge weights represent actual road distances measured via Google Maps. The graph has a density of 0.152, confirming its sparse graph characteristic. Three alternative routes were identified and analyzed. The algorithm was implemented in Python 3 using the heapq module as a priority queue. Results show that the optimal route is A → B → C → E → F → M → N → O via Jl. M.T. Haryono, Jl. Aipda KS Tubun, Jl. Madong Lubis, and Jl. Prof. H.M. Yamin, with a total distance of 6.64 km. This achieves 99.1% accuracy compared to Google Maps, with a deviation of only 0.06 km. The optimal route is 6.25% more efficient than Alternative Route 1 (7.30 km) and 11.9% more efficient than Alternative Route 2 (7.54 km). The algorithm executes in under 1 millisecond with time complexity O((V+E) log V). These findings confirm Dijkstra's Algorithm as highly effective for medium-scale urban road network optimization.

Hypertension is a global health problem that requires ongoing management, one of which is through a low-salt diet. However, many people with hypertension do not adhere to this diet due to a lack of information and understanding of the disease's risks. The Health Belief Model (HBM) can be utilized as a health education method to encourage hypertension management behavior using leaflets. This study aims to analyze the application of the HBM theory in the use of leaflets to increase knowledge about a low-salt diet among hypertensive patients in the community. The method used in this study was a literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines through the steps of identification, screening, eligibility assessment, and selection of articles until 16 articles were obtained that met the inclusion criteria. The results of this study indicate that leaflets are effective in increasing knowledge about a low-salt diet, adherence to health behaviors, and blood pressure control for people with hypertension. The components of the HBM, such as perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action, play a role in shaping risk perceptions and encouraging changes in health behavior. Therefore, leaflets based on HBM are highly recommended as a form of promotional and preventive intervention in nursing practice in the community because they are easy to use, low cost, and support self-management of hypertension.

Rapid urban growth is often linked to the narrative of sustainable development, yet the reality is that fundamental issues remain in the management of urban waste. This paper aims to examine the gap between the concept of a sustainable city and sub-optimal waste management practices. Through a normative legal approach involving an analysis of legislation and relevant literature, it has been found that the implementation of waste management policies continues to face various challenges, such as weak law enforcement, a lack of policy integration, and low levels of public participation. On the other hand, the use of the label ‘sustainable city’ tends to be symbolic and does not yet reflect comprehensive practices. This paper positions the issue of waste as a key indicator in assessing urban sustainability. The novelty of this study lies in its critical approach, which links the discourse on sustainability with the contextual realities of waste management, thereby offering a more reflective and distinct perspective from previous studies.

Micro, Small, and Medium Enterprises (MSMEs) play an important role in improving the community’s economy. However, many MSME actors still face difficulties in managing business finances. These problems were also experienced by the Samiler Crackers MSME in Betro Hamlet, Wonosunyo Village, Gempol District, Pasuruan Regency, particularly in preparing the Cost of Goods Manufactured (COGM), determining selling prices, and managing simple financial reports. This community service activity aimed to improve the understanding and skills of MSME actors in financial management. The implementation method used a Participatory Action Research (PAR) approach through observation, socialization, training, mentoring, and evaluation stages. The results of the activity showed that MSME actors were able to prepare a more detailed Cost of Goods Manufactured by classifying production costs, understand selling price determination based on raw material costs and product quality, and conduct simple financial recording of cash inflows and cash outflows. In addition, simple financial reports helped MSME actors identify income levels and business conditions. This mentoring activity had a positive impact on improving MSME financial management capabilities and is expected to support the sustainability and development of the Samiler Crackers business in Wonosunyo Village.Micro, Small, and Medium Enterprises (MSMEs) play an important role in improving the community’s economy.

The development of Islamic banking activities in Indonesia currently is not matched by adequate understanding among students, particularly regarding the rights and obligations of customers, Sharia contract literacy, and consumer protection mechanisms. This Community Service Activity aims to enhance the understanding of Muara Bungo University students regarding customer rights and obligations, complaint procedures, basic sharia contract literacy, prevention of detrimental service practices, and the resolution process for sharia banking consumer disputes. The activity was attended by 50 students from all faculties and department, conducted using the Participatory Action Research (PAR) approach through the stages of problem identification, planning, implementation with interactive lecture methods, and evaluation. The results of the activity showed a significant increase in understanding, marked by the growing awareness of participants regarding the rights and obligations of customers, understanding of Islamic banking contracts, as well as the ability to comprehend consumer protection concepts and the dispute resolution process effectively. Consumer protection literacy education has proven to have a positive impact on students in preparing themselves to face the banking world, both in the context of employment and business in the future.

This study analyzes normative conflicts in the evolution of local government regulations from Law No. 22 of 1999 to Law No. 23 of 2014, along with the changes following the Job Creation Law. The research background is grounded in the phenomenon of policy pendulum swings, which indicate a shift from radical decentralization toward structured centralization, as well as the disruptions caused by the omnibus law approach. The research aims to identify and classify vertical and horizontal normative conflicts and formulate recommendations for regulatory harmonization. The method used is normative legal research with a legislative and conceptual approach, employing Hans Kelsen’s theory of antinomy as an analytical tool. The research findings identified two main forms of normative conflict: first, a vertical conflict between Law No. 22/1999, which advocates for the broadest possible autonomy, and Law No. 23/2014, which strengthens central control through the concepts of absolute affairs and NSPK, creating a paradox of centralization within decentralization. Second, a horizontal conflict following the Job Creation Law, which centralizes regional licensing authority through the OSS system and revives Article 251 regarding the annulment of regional regulations that have been declared unconstitutional by the Constitutional Court. The implications of this research recommend revising problematic articles and strengthening the role of regions within a just decentralization system.

Until now, truancy behavior is still frequently found among students during school hours. This behavior is caused by various factors, such as waking up late, staying up too late at night, feeling tired or sleepy, vehicle problems such as flat tires, lack of motivation to go to school, and other reasons. This problem has become an important concern for school counselors in providing assistance, one of which is through individual counseling services. Students’ participation in the learning process greatly affects the smoothness of learning and the results achieved at school. If truancy behavior continues to be ignored, it can lead to more serious impacts and even increase the risk of students dropping out of school. Therefore, school counselors have an important role in helping overcome this problem with support from students, subject teachers, and parents. One method that can be applied is individual counseling using the behavior contract technique. This technique aims to help students change negative behavior into more disciplined behavior so that truancy habits can be reduced and not repeated again. This study used a qualitative method with interview techniques for data collection. The results of the study showed that individual counseling services using the behavior contract technique were effective in helping overcome truancy behavior among students.

The preservation of the nation's collective memory is a very important aspect in maintaining national identity, but its existence today is threatened by physical damage and limited access to information. This study aims to explain effective preservation methods to ensure the sustainability of the collective memory as a historical heritage. The methodology applied is qualitative descriptive by collecting data through literature review and document analysis from various literature sources and regulations related to archives. The results of this study show that the implementation of the current preservation strategy still faces major problems, especially the difference between the expected tennis standards and the reality of limited funds and the ability of human resources to carry out restoration. In addition, the digitalization process has not been fully linked to the planned long-term digital preservation management. The implications of this study show that strengthening the collaboration and technical capabilities of archivists is very important so that all historical artifacts of the nation are maintained in their authenticity, protected, and can be widely accessed by future generations.

The results of the study showed that the LKPD booklet  obtained a feasibility percentage of 91.17% in the media aspect and 90.32% in the material aspect with a very feasible category. These results show that the LKPD booklet  Developed has met the eligibility criteria both in terms of appearance and content as teaching materials for learning Indonesian language in elementary schools. However, this research is still limited to the product validation stage, so further research is needed through field trials to determine the effectiveness of LKPD booklet s in improving students' speaking skills in more depth.

The Legal Unit plays a crucial role in ensuring compliance with banking regulations, particularly in managing customer documents related to data protection and legal risk reduction. This study aims to explore the role and performance of the Legal Unit in managing customer files at Bank Sumsel Babel, Kapten A. Rivai Main Branch, and to identify obstacles and possible solutions. The method chosen in this study is qualitative with a descriptive approach. Data were obtained through observation, interviews, and document analysis, which were then analyzed using the interactive model of Miles and Huberman. The research findings indicate that the Legal Unit is responsible for ensuring that document management is carried out regularly, securely, and in accordance with applicable banking regulations. The implementation of Standard Operating Procedures (SOPs), internal supervision, and the use of digital archives contribute to legal compliance and minimize the risk of document loss and information leakage. Problems encountered include limitations in human resources and incompatibility with digital systems. Therefore, improvements in document management technology, training for human resources, and periodic SOP evaluation are needed to improve the effectiveness of the Legal Unit's work and maintain customer trust.

This research examines digital charity practices within Christian media communication on YouTube, focusing on two distinct donation formats: marapthon live stream donations (e.g., 24‑hour fundraising events) and sermon‑based donations (offerings collected during or after online worship services). Despite the rapid growth of faith‑based online giving, a critical problem remains: the absence of an integrated system that aligns these two donation models with Christian values of transparency, accountability, and community stewardship. Existing platforms often treat live marapthon and sermon donations separately, leading to fragmented donor experiences and inefficient fund utilization. Therefore, this study aims to develop a conceptual framework for an integrated digital charity system by comparatively analyzing media communication strategies in both donation contexts. The proposed method is a netnographic comparative analysis, involving systematic observation of YouTube comments, chat logs, and video descriptions from 10 Christian channels (5 marapthon‑focused, 5 sermon‑focused) over six months, supplemented by semi‑structured interviews with content creators and donors. The main findings reveal that marapthon donations emphasize urgency and real‑time social proof, while sermon donations rely on theological framing and pastoral trust. The synthesis proposes a hybrid system architecture incorporating real‑time donation tracking, automated acknowledgment, and weekly theological reflection modules. In conclusion, integrating both models into a single development framework enhances donor engagement and aligns digital charity with Christian communication ethics, offering practical guidelines for church‑based YouTubers and platform developers.
