The use of social media is no longer just for information and entertainment, but has developed into a strategic means in building a positive self-image in the eyes of the public. School students are generally active users of social media whose intensity of use is quite high in daily life. As a group of teenagers who are still in the phase of finding their identity and tend to be emotionally labile, they need the right education to be able to use social media wisely, productively, and responsibly. Community Service activities carried out for students of SMK Wiyata Satya are expected to increase understanding of the importance of personal branding from an early age. Through this activity, students are not only given socialization about the concept of personal branding and social media ethics, but also equipped with practical skills in compiling portfolios and fostering awareness of career planning and goal achievement. At the end of the activity, students presented their self-concept that had been prepared and responded through a questionnaire to evaluate the effectiveness of the entire series of activities.

The rapid and significant development of technology in the world has made online games a very popular form of entertainment among teenagers and students. Easy access to online games through gadgets has led to an increase in the number of teenagers playing online games. This condition has both positive and negative impacts on education, particularly on students' interest in learning. This study aims to analyze in depth the influence of online games on the lives and learning achievements of teenagers based on previous articles. We chose a literature study method for this research, and the data sources were obtained from articles relevant to the discussion. The data collection technique was carried out by reading and examining important information from the articles used. The results of the study show that online games have both positive and negative impacts on teenagers. The positive impacts can be seen in games that are educational and relevant to learning, as they can increase motivation, curiosity, and skills in teenagers. However, if played excessively and without supervision, online games tend to reduce concentration, decrease study time, and impact academic achievement, psychological well-being, and the health of adolescents. Therefore, the role of parents and teachers is crucial in controlling, guiding, and monitoring the use of online games so that adolescents can use them wisely and support the learning process wherever they are.

The diversity of social media used by teenagers today can influence Fear of Missing Out (FoMO) behavior, a condition where someone feels left out of information, trends, or activities carried out by others. This condition is characterized by fear, anxiety, difficulty controlling the desire to stay connected, and a tendency to compare oneself with others on social media. Teenagers are the group most vulnerable to FoMO due to their high intensity of social media use and their still-developing social needs. This reseach seeks to examine the association between scial media diversity and FoMO behavior among eleventh-grade student at SMAN 4 Tuban. The study employed a quantitative analytic design using a cross-sectional approach. The research population consists of all 11th grade students, totaling 157 respondents, selected using simple random sampling. The instruments used are a social media diversity questionnaire and a FoMO behavior questionnaire. Data analysis uses the Chi-Square test with a significance level of α = 0.05. The results of the study show a p-value of 0.000, which means p < 0.05, so H1 is accepted. This shows that there is a significant relationship between social media diversity and FoMO behavior in adolescents. The more diverse the social media platforms used, the higher the tendency for adolescents to experience FoMO. Based on these results, it can be concluded that social media diversity influences FoMO behavior among 11th grade students at SMAN 4 Tuban.

Vaping is when you inhale a mist through a power based device, filled with flavourings, chemicals, and nicotine (Texas Health and Human Services, nd). Teenagers tend to vape due to external influences such as advertisements and social interactions, which has a significant contribution in the role of gaining societal acceptance of vaping amongst teenagers (CDC, nd). However its use in teenagers is illegal as per the Indonesian Government Regulation Number 109 2012, which restricts individuals below 18 years old from vaping. A study conducted in 2018 has reported that teenagers have started vaping from 2017. Despite rules and regulations, teenagers are still able to access it which makes the law enforcement ineffective that leads to teenagers being able to have access to vapes. This research will investigate the influence of social media and peer pressure on underage vaping, focusing on how contents on social media, their peers along with social interactions shape the perspective and behaviour of a teenager towards vaping. This following topic is important as social media plays a significant role in the normalisation of vaping despite harmful effects. It aims to recognize how social media and interactions among fellow peers influence a teenager. With the use of qualitative and quantitative methods such as surveys and interviews, it will also apply theories from 3 thinkers to have a better understanding of a teenager’s decision.

Menstrual stress is a common reproductive health problem among adolescent girls, which can interfere with learning activities, concentration, and overall quality of life. This community service activity aimed to improve the ability of female students to manage menstrual stress through education and practice of deep breathing techniques at SMPN 2 Rambutan, Banyuasin Regency. The activity used a one-group pretest–posttest pre-experimental design involving 30 female students who had experienced menstruation. Health education was delivered through interactive lectures, discussions, and practical demonstrations of deep breathing techniques, while evaluation was conducted using pre-test and post-test questionnaires on menstrual stress levels. The results showed a reduction in menstrual stress, with most participants shifting from moderate stress before education to mild stress after the intervention. These findings indicate that deep breathing techniques are effective in helping students independently manage menstrual stress. Therefore, health education combined with practical deep breathing exercises is recommended to be implemented continuously in schools as a promotive and preventive strategy for adolescent reproductive health.

Divorce is the legal and religious termination of a husband-wife relationship. This severance of the relationship can have psychological consequences, making children more susceptible to depression. These psychological impacts include deep sadness, resulting in depression, feelings of loss, shame, anger, disappointment, denial, self-acceptance, and feelings of blame toward the parents. These psychological impacts are naturally the result of the support, emotional support, and presence of the parents before, during, and after the divorce. This study employed a qualitative research method with a phenomenological approach, conducted through semi-structured interviews. The aim is to raise awareness among readers that divorce not only impacts the husband and wife but also the psychological impact on children, which is often considered unimportant. However, the mental health of children after divorce is a crucial issue that requires attention. This is where the role of parents is crucial in shaping their character and psychological development. This study concludes that children who are victims of divorce tend to seek out activities outside the home, as the integrity of their home is no longer there. Children experience sadness and loss most acutely. Furthermore, children are more wary of future relationships due to a loss of trust in the meaning of romantic relationships. Low self-acceptance also makes it difficult for children to control their emotions.

This study aims to analyze the opportunities, threats, strengths, and weaknesses of Arch Barbershop, a modern barbershop in Maumere City. The study was conducted using a descriptive approach through observation of the business environment, competitor analysis, and identification of local consumer preferences. The analysis shows that Arch Barbershop has promising opportunities due to the increasing trend of grooming among teenagers and young adults, and the lack of barbershops offering modern and consistent service concepts in the area. However, this business also faces threats in the form of competition from new barbershops, rapidly changing consumer preferences, and dependence on barber skills as the spearhead of service quality. Furthermore, internal weaknesses such as limited space, inflexible operating hours, and a less than optimal variety of services pose challenges to business development. By understanding these opportunities, threats, strengths, and weaknesses, Arch Barbershop can formulate a more effective development strategy to increase its competitiveness and business sustainability in Maumere City.

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.

Adolescent obesity is a health problem that arises due to an imbalance between energy intake and expenditure, one of which is influenced by a diet high in fat and low in fiber. This condition needs attention because it has an impact on the risk of chronic diseases in adulthood. This study aims to analyze the effect of substitution of katuk leaf flour and yellow sweet potato flour on the nutritional content and acceptability of muffins as a healthier alternative to high-fiber and low-fat snacks for adolescents. This laboratory's experimental research used a Complete Random Design (RAL) with four formulations (P0, P1, P2, P3). The analysis carried out included a proximate test to determine the nutritional content and an organoleptic test to assess the level of acceptance of panelists. The results of the study show that the substitution of katuk leaf flour and yellow sweet potato flour can increase fiber content and significantly reduce fat content. The best formulation is found in P2 with the highest level of preference. Thus, the use of these two types of flour has been proven to be able to improve the nutritional quality of muffins without reducing the acceptance of panelists, so that it has the potential to be a nutritious snack choice for teenagers.
