Waste management has become a critical environmental issue at both global and national levels due to increasing population and changing consumption patterns. In Indonesia, waste generation exceeds 60 million tons annually, with a significant portion consisting of plastic waste that requires hundreds of years to decompose. One of the main challenges in addressing this issue is the low level of public awareness and understanding regarding waste types and their decomposition time. This community service program conducted by students of Universitas Negeri Padang aims to improve environmental awareness through environmental education and community empowerment using an innovative visual medium in the form of waste decomposition time educational boards. The activity was implemented in Pasar Hilir Hamlet, Lumindai Village, using a participatory approach involving observation, socialization, board design, production, and installation. The results indicate that the program successfully enhanced community knowledge regarding the differences between organic and inorganic waste and their environmental impacts. The educational boards, placed in strategic locations near waste disposal areas, function as effective visual tools that continuously deliver information and reinforce environmentally responsible behavior. In addition, this program contributes to improving environmental cleanliness, strengthening community participation, and increasing environmental literacy. Therefore, the innovation of waste decomposition time educational boards serves not only as an informative medium but also as a sustainable educational tool to promote long-term behavioral change toward environmental awareness.

Many symptoms appear as signs of moral decline such as free association, violence, crime, and other deviant and reprehensible behavior. Some of the impacts that have been seen include the lack of children's ability to communicate, wanting everything instant without having to know the process, having an egotistical character and many more. This then needs to be realized that it is the responsibility of parents, educators, society, even the nation and state to protect children, especially in the field of morals and character. Here, teachers have a major role in shaping students' character through role models, cooperation between teachers, and positive behavioral habits. In shaping the character of students who are moral, this study identifies effective curriculum management strategies, such as the development of relevant syllabuses, the use of interactive teaching methods, and ongoing teacher training. In addition, this journal emphasizes the importance of collaboration between stakeholders, including teachers, supervisors, parents, and communities, as well as the use of information technology to improve the quality of Islamic religious education. And the implementation of effective strategies for Islamic Education teachers instills leadership character, honesty, and noble morals in students. So it can be concluded that the environment and rapid technological developments have a high influence on students' character, thus causing a decline in students' character, especially in terms of morals and ethics.

The rapid growth of short-video-based social media platforms, particularly TikTok, has significantly influenced students learning behavior and productivity. This study aims to analyze the relationship between TikTok usage and students learning productivity. A qualitative literature review method was employed by examining relevant national and international scholarly articles published between 2021 and 2026. The data were analyzed using thematic synthesis to identify consistent patterns and key factors shaping learning productivity in the context of TikTok usage. The findings reveal a consistent pattern indicating that TikTok usage exerts an ambivalent impact on students learning productivity. Excessive and entertainment oriented use is associated with decreased concentration, increased academic procrastination, and poor time management. In contrast, purposeful use of TikTok through educational content and microlearning formats contributes to higher learning motivation, academic engagement, and creativity. These effects are strongly influenced by usage objectives, duration of consumption, and students self regulation abilities. This study concludes that TikTok is not a single determinant of learning productivity but functions as an amplifier of students learning behaviors. The findings contribute to the literature on social media and education by providing a conceptual foundation for developing digital literacy and time management strategies in higher education.

The rapid development of information technology has transformed social media into a digital space that plays a crucial role in shaping the mindset, behavior, and lifestyle of young generations. TikTok is one of the most dominant platforms used by Generation Z, particularly students, due to its ability to present algorithm-based content that aligns with user interests. This condition has the potential to cause psychological stress in the form of Fear of Missing Out (FOMO), which reflects social anxiety due to the perception of being late in keeping up with trends, information, or experiences that hold a dominant position in the social landscape. This research initiative aims to examine the influence of TikTok usage on the lifestyle configurations of Generation Z students, with FOMO serving as a determinant that strengthens this relationship. This study is designed within the quantitative tradition with a positivist epistemological orientation. The study population includes 250 students from the Faculty of Computer Science at the National Pasim University in Bandung, with a sample size of 72 respondents derived using Slovin's formula. The analysis results indicate that TikTok usage and the level of FOMO have a positive and significant impact on changes in students' lifestyles. The regression coefficient estimates are in the positive direction, with a significance value exceeding the critical threshold of 0.05, indicating a unidirectional relationship between the variables. The model determination estimate, at around 57.5%, confirms that TikTok and FOMO are able to explain a significant portion of the variation in students' lifestyles, while the remainder is influenced by factors outside the scope of this study. This finding confirms that TikTok functions not only as a medium of entertainment but also as an agent shaping lifestyles influenced by social and psychological pressures. Therefore, strengthening digital literacy is crucial so that students can use social media more rationally and responsibly.

Bullying in junior high schools often results in serious psychological and social impacts, such as fear, low self-esteem, and decreased academic achievement. This study aims to examine the implementation of group guidance services using psychodrama techniques in addressing bullying behavior in junior high school students. The method used was a qualitative approach with a library research study, utilizing various existing sources such as scientific journals, books, and articles relevant to the topic of bullying and psychodrama. Data were collected through a literature search, selecting appropriate sources, and grouping them based on the study theme. Data analysis refers to the Miles and Huberman model, which includes data reduction, data presentation, and conclusion drawing. The results of the study indicate that the application of psychodrama techniques in group guidance can increase empathy, self-awareness, and social communication skills in students, resulting in significant changes in the intensity and frequency of bullying behavior. Thus, psychodrama techniques can be a relevant approach in group guidance services to address bullying behavior in junior high school students, as they can encourage deeper social understanding and emotional changes.

This literature study examines the process of self-regulation in transforming compliance with school rules originating from external pressure into behavioral regularity emerging from personal awareness, and its impact on the effectiveness of student learning outcomes. Using a qualitative approach with content analysis method, this study synthesizes relevant literature to build a theoretical framework on how self-regulation facilitates the internalization of disciplinary values. The findings reveal that self-regulation occurs through a series of interconnected stages including goal setting, strategy planning, self-monitoring, evaluation, and adjustment. The success of this process is determined by internal motivation, appropriate environmental support, positive direct experiences, and healthy emotional management. Strong self-regulation directly impacts learning outcome effectiveness through improved cognitive strategies, strengthened intrinsic motivation, enhanced time and environment management, and developed capacity to constructively cope with failure. Learning outcomes achieved through self-regulation processes are characterized by lasting understanding, knowledge transfer ability, and the formation of lifelong learning dispositions. Schools and teachers play strategic roles in strengthening self-regulation through curriculum design that supports autonomy, formative feedback, role modeling, and collaboration with parents. This study contributes theoretically by positioning self-regulation as the central mechanism bridging external influences and internal disposition formation.

This study focused on addressing the problem of low self-confidence among seventh-grade students at SMP In Tana Toraja. The issue was identified through several behaviors, such as difficulty in voicing opinions, lack of courage to stand in front of the class, and minimal participation during the learning process. To address the identified issue, the study was designed to enhance students’ self-confidence through group guidance activities incorporating the sociodrama technique. This investigation adopted a Guidance and Counseling Action Research approach implemented across two consecutive cycles, each involving planning, action implementation, observation, and reflection. The participants consisted of 30 students, while data were collected through questionnaires and observation instruments. The results indicated that students’ self-confidence developed progressively over time. In the initial condition, most students were still classified in the low-confidence category, but improvement began to appear in cycle one and became more significant in cycle two. These changes were reflected in students’ increased confidence in performing, better communication skills, and stronger active participation in group activities. The sociodrama technique provides direct social interaction experiences that help students develop their self-confidence. Based on the results, the use of group counseling activities incorporating sociodrama emerges as a viable strategy for school counselors to support the development of students’ self-confidence.

Students in the transition period are vulnerable to experiencing mental health problems and tend to self-diagnose due to easy access to information and low mental health literacy. This research aims to determine the relationship between mental health literacy and the tendency to make a diagnosis in students at the Faculty of Public Health, Nusa Cendana University, Kupang. This type of research is quantitative research with a correlational approach. Respondents in this study numbered 301 people using probability sampling techniques. Data collection techniques used the mental health literacy scale and self-diagnosis scale. Data analysis uses the product moment correlation test. The research results show that there is a significant negative relationship between mental health literacy and self-diagnosis (r = -0.846 < 0.05), which means that the higher the mental health literacy, the lower the tendency for self-diagnosis in students, and vice versa. In addition, mental health literacy contributed 71.6% to the tendency of self-diagnosis. It is hoped that students not only have a high level of mental health literacy but also quality, so that they realize that self-diagnosis is an inappropriate action and students are expected to take advantage of available professional mental health services.

This study aims to analyze the effect of financial literacy and lifestyle on financial management of students of the Management Study Program at Universitas Pamulang. This research uses a quantitative method with an associative approach, with data collected through questionnaires distributed to 160 respondents. Data analysis was conducted using validity tests, reliability tests, classical assumption tests, simple and multiple linear regression analysis, t-test, F-test, and coefficient of determination (R²). The results show that partially financial literacy has a positive and significant effect on financial management with a t-value of 7,161 > t-table 1.975 and a significance value of 0.000 < 0.05, while lifestyle also has a positive and significant effect with a t-value of 6,881 > t-table 1.975 and a significance value of 0.000 < 0.05. Simultaneously, financial literacy and lifestyle have a significant effect on financial management with an F-value of 853.671 > F-table 3.05 and a significance value of 0.000 < 0.05. The coefficient of determination of 0.916 indicates that 91,6% of the variation in students’ financial management is explained by financial literacy and lifestyle, while the remaining 8,4% is influenced by other factors outside this study.

The implementation of Clean and Healthy Living Behavior (PHBS) begins at an early age, particularly among school children, who learn extensively from their surrounding environment through the School Health Program (UKS). Although the family is the primary unit in shaping PHBS habits, parents’ busy schedules often lead children to interact more with teachers and peers at school. This study aims to determine the effectiveness of the UKS program on students’ PHBS at SD Lambaro Angan, Darussalam District, Aceh Besar Regency in 2024. This research employed a cross-sectional design with a population of 321 students and a sample of 76 respondents. Data collection was conducted on March 4, 2024. The results indicate that the UKS program has a significant effect on students’ PHBS, including habits such as washing hands with running water and soap, purchasing healthy snacks at the school canteen, disposing of waste properly, participating in physical exercise, not smoking at school, eliminating mosquito larvae, and using school sanitation facilities (p < 0.05). However, no significant effect was found on activities such as weighing body weight and measuring height. In conclusion, the UKS program is effective in improving students’ PHBS. These findings are expected to provide input for schools to optimize the implementation of UKS and enhance PHBS promotion so that students can apply clean and healthy living behaviors in their daily lives.

This study aims to analyze and examine the effect of financial literacy and self-control on financial management behavior, with financial attitude as an intervening variable among accounting students at universities in Lamongan. This research employed a quantitative approach using a survey method through questionnaire distribution via Google Form. The population consisted of accounting students at universities in Lamongan, with a total sample of 232 respondents selected using probability sampling with a simple random sampling technique.

Drug abuse among adolescents has been increasing, including among youth in Papua. According to data from the National Narcotics Agency (BNN) of Papua Province, there was a 1.73% increase in 2023. One of the contributing factors to adolescent involvement in drug abuse is low self-control. This study aimed to provide self-control training to help prevent drug abuse among adolescents independently. The program involved 37 vocational high school students in Jayapura City and employed a one-group pretest–posttest experimental design without a control group. The intervention consisted of self-control training delivered through lectures, discussions, and a structured learning module. The results indicated a significant improvement in self-control before and after the intervention, as evidenced by a significance value of 0.000 (p < 0.05) using a paired sample t-test, with an increase in the mean pre-test score (M = 46; SD = 7) to the mean post-test score (M = 48; SD = 6). These findings suggest that students of SMK Negeri 9 Jayapura experienced an improvement in self-control after participating in the training. Practically, this study demonstrates that self-control training can serve as an effective psychological intervention to address drug abuse and harmful substance use among adolescents. This intervention not only helps reduce addictive behaviors but also has the potential to enhance students’ quality of life and academic achievement.

This study examines the effectiveness of classical guidance services in reducing gadget addiction among twelfth-grade students. Gadget addiction has become a growing concern in modern educational settings, as excessive use of digital devices often interferes with students’ academic performance, social interactions, and emotional stability.

Participants were selected through purposive sampling based on indications of high gadget dependency. The intervention was conducted through structured classical guidance sessions focusing on awareness building, self-control improvement, and practical time management skills. Data were collected using a validated gadget addiction scale administered before and after the intervention, then analyzed using parametric statistics to determine the significance of the results. The findings indicate a significant decrease in gadget addiction levels following the implementation of the classical guidance program. This result highlights the importance of preventive and developmental counseling services in schools. The study implies that classical guidance can serve as an effective strategy to help students regulate their digital behavior and foster healthier lifestyle patterns in the digital era.

Online gambling is a form of addictive behavior that often begins with simple experimentation. Early wins tend to encourage individuals to continue gambling with increasingly larger stakes, driven by the belief that higher bets will lead to greater profits. Along with the rapid advancement of digital technology, online gambling has become more accessible to various groups, including university students, through convenient and flexible online platforms. Although it is often perceived as a form of entertainment, online gambling has significant negative impacts. This study aims to analyze the effects of online gambling on students’ mental health. The research uses a qualitative approach, with data collected through observations and interviews involving respondents who engage in online gambling activities. The findings reveal that online gambling has detrimental effects on students’ psychological well-being, including increased levels of stress, anxiety, depression, and sleep disturbances. Furthermore, it contributes to decreased concentration, reduced learning motivation, and declining academic performance. Therefore, stronger preventive measures and educational efforts are necessary to minimize the negative impacts of online gambling among university students.

Truancy among high school students continues to be a serious concern that has negative effects on both academic outcomes and social development. This study seeks to analyze the application of reality therapy as an intervention to minimize truancy behavior. The research utilizes a literature review approach by evaluating six relevant scholarly articles published over the past decade. The findings suggest that truancy is caused by a combination of internal factors, such as lack of learning motivation and feelings of boredom, and external factors, including family environment and peer influence. Conventional approaches that rely heavily on punishment and external control are considered less effective in creating lasting behavioral improvements. On the other hand, reality therapy emphasizes personal responsibility, present actions, and self-assessment, allowing students to better understand their behavior and make more positive decisions. The results demonstrate that this approach enhances students’ self-awareness, responsibility, and decision-making abilities. Therefore, reality therapy can be regarded as an effective alternative counseling method to address truancy behavior in schools and to support long-term behavioral change.
