The results of the 2022 PISA indicate that science skills and interest in Indonesia are still low. One way to increase interest in science is by introducing inventor figure of science and techonology. However, alternative learning media that are communicative and relevant to adolescents' media consumption habits are needed. Therefore, this study aims to design a character design for an inventor in the field of science and technology for a Webtoon comic as an educational tool for adolescents aged 15–18. This study used qualitative and quantitative methods. The qualitative method was used to understand the needs and interests of the target audience and to gather information from the literature for scientific sources in designing the inventor character. The quantitative method was used as one of the character design evaluation criteria, based on voting results by adolescents aged 15–18. The character design used Marika Nieminen's principles: demographics, silhouette and shape, color, and characteristics. Several alternatives were used to generate character designs, which were then evaluated to determine the final design. The character design evaluation will be assessed using several variables within an evaluation framework.

Dysmenorrhea or menstrual pain, is a common health issue among adolescent girls, often disrupting daily activities and quality of life. Effective management of dysmenorrhea is strongly influenced by the level of knowledge and attitudes of adolescent girls toward this condition. This literature review aims to analyze the relationship between knowledge and attitudes regarding the management of menstrual pain among adolescent girls. Various studies indicate that while adequate knowledge about dysmenorrhea is important, the correlation between knowledge and attitude is not always significant. Some research finds that good knowledge does not necessarily translate into a positive attitude towards pain management, as other factors such as stress, anxiety, and reluctance to take action also play a role. However, there are studies that show a positive relationship between increased knowledge and better attitudes toward dysmenorrhea management,  although the strength of this association is very weak. Most adolescents tend to choose non-pharmacological management, such as rest and warm compresses, but many still ignore menstrual pain due to a lack of knowledge and information. Therefore, educational interventions and counseling in schools are essential to improve knowledge and foster positive attitudes in managing dysmenorrhea among adolescent girls. These efforts are expected to help adolescent girls manage menstrual pain more effectively and enhance their quality of life.

The development of digital technology has increased the popularity of online games among adolescents. Excessive intensity of online gaming may have negative effects on health, particularly sleep quality and aggressive behavior. This study aimed to determine the relationship between the intensity of online gaming and sleep quality as well as aggressive behavior among tenth-grade students at SMAN 38 South Jakarta in 2025. This research is quantitative associative method with a correlational analytic design using a cross-sectional approach. The population in the study was 145 students, with a sample of 117 respondents selected using random sampling. Data analysis was conducted using the Chi-Square test. The results showed a significant relationship between the intensity of online gaming and sleep quality with a p-value of 0.001 (p < 0.05), as well as a significant relationship between the intensity of online gaming and aggressive behavior with a p-value of 0.001 (p < 0.05). Therefore, the null hypothesis (H0) was rejected and (Ha) was accepted. In conclusion, higher intensity of online gaming is associated with poorer sleep quality and increased aggressive behavior among adolescents. It is expected that adolescents can manage and limit their online gaming time wisely to reduce its negative impact on health and behavior.

This study aims to analyze the strategies implemented by Islamic Religious Education (PAI) teachers in shaping adolescent personality at SMA Negeri 1 Sragen. The research employed a qualitative approach with a descriptive case study design. Data were collected through participatory observation, in-depth interviews, and document analysis, and were analyzed using an interactive data analysis model. The findings indicate that personality development strategies were carried out in a planned, systematic, and collaborative manner through five main approaches: role modeling, religious habituation, integration of values into classroom instruction, personal mentoring, and collaboration among teachers. Role modeling emerged as the most dominant strategy, as students tend to imitate teachers’ behavior in daily interactions. Religious programs such as congregational prayer, Qur’anic recitation, Islamic student organization activities, and Friday religious programs function as instruments for internalizing religious and social values. These findings affirm that adolescent personality development requires an integrated strategy embedded within school culture and supported by a conducive educational environment.

Teenage brawls have become an increasingly urgent social issue, considering the destructive impact they cause. This study aims to explore the causes and negative impacts of student brawls through a literature review. By analyzing 20 related academic articles, it was found that the triggers of brawls can be divided into two main dimensions. The internal dimension includes factors such as deindividuation, identity crisis, and low self-regulation, while the external dimension encompasses ineffective parenting styles, peer influence, and provocation through social media. The impact of brawls is significant, not only on physical aspects and fatalities but also on psychological disturbances, moral decline, stigmatization, and serious legal consequences. This study concludes that a comprehensive intervention approach is needed, involving school counseling services, education on better parenting, and community monitoring to reduce the tendency for teenage aggression. This strategy is expected to address the root causes of brawls in a more structured and effective manner, creating a safer environment and supporting positive teenage development.

Background: Adolescence is a transitional period from childhood to adulthood, with signs of entering adolescence including physical and psychological changes. The adolescent phase is marked by physiological maturation such as the growth of tissues and body organs. This requires adolescents to have sufficient nutritional intake. If the intake is inadequate, it can lead to disturbances in the body's metabolic processes. Nutrient deficiencies, particularly iron (Fe), can cause nutritional anemia. Low hemoglobin levels can occur due to insufficient nutrient intake from food, especially nutrients that support hemoglobin formation. Objective: The objective of this study is to determine the relationship between hemoglobin levels and BMI scores in female adolescents at SMA N 3 Boyolali. Method: The research design was correlational analytic, with a sample of 76 female students at SMA Negeri 3 Boyolali. The sampling technique used random sampling according to inclusion and exclusion criteria. The research instruments included a digital hemoglobinometer, a digital step-on scale, and a microtoa. Data were analyzed using the Spearman Rank test. Results: Bivariate analysis using the Spearman Rank statistical test showed r = 0.343 with a p-value of 0.002 < 0.05, indicating that Ha was accepted. An r of 0.343 is equivalent to 34.3%, indicating a low strength of association. Conclusion: There is a significant relationship between hemoglobin levels and BMI scores in adolescent girls.

Teenage pregnancy remains a reproductive health issue in Indonesia, including in Batam City. According to data from the Batam City Health Office in 2024, there were 18 cases of teenage pregnancy (0.06%) with the Lubuk Baja Health Center being one of the highest areas. Pregnant teenagers are at high risk of complications such as anemia, malnutrition, and low birth weight (LBW), which contribute to high rates of maternal and infant morbidity. This study used a descriptive method with a case study approach on Ny. S, an 18-year-old teenager with a pregnancy in the Lubuk Baja Health Center area of Batam City in 2025. Data collection was conducted through interviews, observations, physical examinations, and SOAP documentation following the 7-step Varney obstetric management. The findings revealed that Ny. S experienced mild complaints such as nausea, reduced appetite, and anxiety about her pregnancy. After three visits, the mother's complaints decreased, appetite improved, anxiety decreased, and nutritional status was within normal limits. Comprehensive midwifery care with a biopsychosocial approach was proven effective in improving both the physical and mental health of pregnant teenagers and preventing pregnancy complications.

High school adolescents are in a vulnerable developmental phase towards emotional and behavioral problems due to rapid biological, cognitive, and social changes. Limitations in emotional management can trigger the emergence of problematic behavior, such as aggressiveness, violations of school rules, conflicts with peers, and bullying, both directly and through digital media. This article aims to analyze problematic behavior in high school adolescents from the perspective of emotional conditions. This study used a qualitative approach with a literature review method of 20 national and international scientific articles obtained through Google Scholar and analyzed descriptively-thematically. The results of the study indicate that adolescent problematic behavior is influenced by the interaction of individual, family, school, and social environment factors that are increasingly complex. Low emotional regulation and emotional intelligence increase the tendency for maladaptive behavior, while family support, a conducive school climate, and Guidance and Counseling services act as protective factors. Therefore, a holistic and sustainable approach is needed through strengthening emotional intelligence, preventive Guidance and Counseling services, and the development of life skills to support the social-emotional development of adolescents.

Physiological changes in adolescents during the transition period, both biologically, cognitively, psychosexually, and psychosocially, are very vulnerable to various risky behaviors such as premarital sexual behavior, abortion, unwanted pregnancy, STIs, and drug use. One effort to increase adolescent awareness about premarital sex is health education. This study identified the effectiveness of audiovisual media and leaflets about premarital sexual behavior on the knowledge and attitudes of adolescents at SMA Negeri 20 Seram Bagian Barat.

The Wilcoxon test results for the intervention group showed a p-value of 0.001 (p < 0.05), indicating a significant difference in adolescent knowledge and attitudes before and after health education using audiovisual media. The control group showed a p-value > 0.05, indicating no significant difference in adolescent knowledge and attitudes before and after health education using leaflets. The Man-Whitney test results showed a p-value < 0.000 (p value < 0.05) for the intervention group post-test. It was concluded that there was a significant difference in health education using audiovisual media and leaflets regarding premarital sexual behavior on adolescent knowledge and attitudes at State Senior High School 20, West Seram.  

Nutritional status plays an important role in shaping body image among adolescents, particularly female adolescents who experience rapid physical and psychosocial changes. Adolescents with nutritional problems are more likely to feel dissatisfied withitheiribody shape, whichimay lead to unhealthy behaviors such as strict dieting or excessive eating to gain weight. Thisistudy aimed toianalyze theirelationship betweeninutritional statusiand bodyiimage amongifemale adolescentsiat SMK Negeri 1 Palu. This research employedia quantitativeiapproachiwith aicross-sectionalidesign. Aitotal ofi169 femaleistudentsiwere selected using stratified random sampling. Body image data were collected using the Body Self Relation Questionnaire–Appearance Scale, while nutritional status was assessed using Body Mass Index for Age (BMI-for-Age) and Height for Age (HFA). Data were analyzed using the Spearman Rank correlation test. The results indicated that there was no significant relationship between nutritional status based on BMI-for-Age and body image, with a p-value of 0.329. Similarly, no significant relationship was found between Height-for-Age and body image among female adolescents, with a p-value of 0.892. Most respondents were aged 16–17 years, had a negative body image perception, normal BMI-for-Age nutritional status, and normal Height-for-Age category. These findings suggest that body image among female adolescents is not solely influenced by nutritional status but may also be affected by other psychosocial and environmental factors. Therefore, future research is recommended to apply a cohort study design and explore other determinants of body image, such as social media exposure, peer influence, and infectious diseases, to provide a more comprehensive understanding of factors affecting adolescent body image.
