Premarital sex is sexual intercourse outside of legal or religious marriage. This behavior can cause various problems such as sexually transmitted diseases, unplanned pregnancies, and encourage early marriage. Analyzing the determinants of adolescent premarital sex based on the Health Belief Model. Using a literature review approach, this study analyzes several academic references such as journals, books, encyclopedias, and others that discuss the topic of premarital sex among adolescents based on the Health Belief Model (HBM) Theory. This study uses seven journals, with sources from the last six years. The study began in October-November 2025. Based on the analysis, there is a relationship between perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, cues to action, and premarital sex behavior among adolescents. The conclusion shows that in all seven studies, the main components of HBM are significantly related to this behavior. For adolescents, it is recommended to better understand premarital sex behavior by seeking appropriate information and selecting positive friends and social environments so as not to be influenced by negative things or the urge to engage in premarital sex behavior.

This study aims to identify factors associated with fast food consumption behavior among adolescents based on the Social Cognitive Theory (SCT) through a literature review. A descriptive literature review was conducted using nine peer-reviewed articles published between 2021 and 2025, retrieved from Google Scholar, PubMed, and ScienceDirect. The findings indicate that adolescent fast food consumption behavior is influenced by two main components of SCT, namely personal factors and environmental factors. Personal factors were predominantly examined through the knowledge variable, which showed inconsistent associations with fast food consumption, while other personal variables, although mostly related, lacked consistent empirical support across studies. In contrast, environmental factors demonstrated more consistent associations, particularly peer influence, mass media exposure, parental influence, and pocket money, which were repeatedly identified as significant determinants of fast food consumption among adolescents. In conclusion, adolescent fast food consumption behavior is more strongly influenced by environmental factors than by personal factors, highlighting the importance of multi-level interventions that address social and environmental contexts in shaping healthy eating behaviors among adolescents.

The nutritional status of toddlers is an important indicator that reflects the level of public health in a region. This study aims to analyze the nutritional status of children aged 0–5 years in Teupin Desa Teupin Gapeuh Kecamatan Tanah Pasir Kabupaten Aceh Utara. This research employed a descriptive quantitative method using secondary data obtained from health records and posyandu (integrated health post) reports. The study involved a total of 60 children under five, consisting of 33 boys and 27 girls. The findings revealed that based on the weight-for-age (W/A) index, 81.7% of children had normal nutritional status, 13.3% were undernourished, and 3.3% were severely undernourished. Based on height-for-age (H/A), 90.0% were normal, 5.0% were short, and 3.3% were very short. According to the weight-for-height (W/H) index, 83.3% were normal, 11.7% were undernourished, and 5.0% were at risk of overweight. Furthermore, the prevalence of stunting, wasting, and underweight were 8.3%, 11.7%, and 16.7% respectively. These results indicate that although most children have normal nutritional status, some still experience nutritional deficiencies that require special attention. Therefore, health workers and local governments need to strengthen nutrition education programs, increase community awareness of balanced nutrition, and improve monitoring of child growth to prevent malnutrition in the area

Food safety is a crucial aspect of public health, particularly for elementary school children who frequently consume street food or snacks sold within school environments. Food handlers play a key role in determining the level of hygiene and sanitation of the food served. This study aims to analyze the factors associated with food handlers’ hygiene behavior in elementary school canteens in Telanaipura District, Jambi City. This research employed a quantitative method with a cross-sectional approach involving 41 food handlers as respondents. Data were collected through structured interviews using questionnaires and direct observations based on hygiene and food sanitation standards in accordance with the Regulation of the Minister of Health No. 1096/Menkes/PER/VI/2011. Data were analyzed using univariate and bivariate methods with the Chi-Square test at a significance level of p < 0.05. The results showed that most food handlers exhibited poor hygiene behavior (61.0%). There were significant relationships between knowledge (p = 0.048), attitude (p = 0.000), and availability of facilities and infrastructure (p = 0.000) with hygiene behavior, while education level showed no significant association (p = 0.187). It can be concluded that improving hygiene behavior requires continuous training, supervision, and provision of adequate sanitation facilities to support food safety in school environments.

This study aims to analyze the relationship between the implementation of Law Number 16 of 2019 on Marriage and socioeconomic status with public awareness of early marriage in Wirosari District, Grobogan Regency. The phenomenon of early marriage in this area remains high despite the existence of regulations that set a minimum marriage age. A quantitative approach was used, with data collected through questionnaires, interviews, and documentation. The research population consisted of 169 couples who married early in the last three years, with a sample of 43 couples selected through purposive sampling. The data were analyzed using the product moment correlation test to determine the relationships between the variables. The results show that the implementation of Law Number 16 of 2019 has no significant relationship with public awareness of early marriage, indicating that despite the existence of the regulation, the public's understanding of the importance of the minimum marriage age is still not optimal. Conversely, socioeconomic status has a positive and significant relationship with public awareness, indicating that the higher the socioeconomic status, the higher the public's awareness of the negative impacts of early marriage.

Investment is one of the key drivers of national economic growth as it contributes to capital formation, job creation, and the expansion of production capacity. However, investment realization is dynamic and inherently uncertain, influenced by both domestic and global economic conditions. This study aims to analyze the probability of investment growth in Indonesia based on investment realization data for the first quarter of 2025. The research employs a quantitative approach using descriptive statistical analysis and probability analysis. The data used are secondary data obtained from official publications of the Investment Coordinating Board (BKPM), including national investment realization, Domestic Investment (PMDN), Foreign Direct Investment (FDI/PMA), and regional distribution of investment. The results indicate that investment realization in the first quarter of 2025 reached Rp465.2 trillion, equivalent to 24.4% of the national investment target for 2025. Investment probability is relatively balanced between PMDN and PMA, as well as between Java and non-Java regions, reflecting a stable investment climate and early progress in regional development equity. Overall, the probability of investment growth in Indonesia in 2025 remains favorable; however, achieving the annual investment target largely depends on the consistency of investment realization and the effectiveness of government policies in the subsequent quarters.

The informal trading of Mobile Legends: Bang Bang game accounts through social networking platforms has expanded rapidly alongside the acceleration of digital technology and the growing integration of online gaming into contemporary lifestyles, particularly among younger demographics. Game accounts characterized by high competitive rankings, exclusive virtual assets, and accumulated in-game achievements have increasingly been commodified and exchanged through social media channels such as Facebook, Instagram, and TikTok, predominantly utilizing electronic payment instruments, including digital wallets. Despite its widespread practice, this form of transaction frequently generates legal complications, most notably in relation to consumer protection. Buyers are often exposed to substantial risks, including fraudulent representations, discrepancies between promised and actual account specifications, unauthorized resale, and the revocation of account access after payment completion. This study seeks to critically examine the legal framework governing the trading of Mobile Legends accounts and to assess the extent to which consumer protection mechanisms are afforded under Law Number 11 of 2008 concerning Electronic Information and Transactions and Law Number 8 of 1999 concerning Consumer Protection. Employing a normative juridical research design, this study applies statutory and conceptual approaches supported by the analysis of primary, secondary, and tertiary legal materials. The findings indicate that consumer protection within online game account transactions remains structurally insufficient, primarily due to the absence of explicit legal recognition of digital game accounts as legally protected objects. Consequently, the study underscores the necessity of adopting progressive legal interpretation and formulating specific regulatory instruments to enhance legal certainty and ensure more effective consumer protection within the evolving landscape of digital transactions.

This study aims to analyze the supervisory strategy of the Panwascam (Central Election Supervisory Agency) of Sinjai Borong District in handling election violations in the 2024 Simultaneous Regional Elections in Sinjai Regency. The study focuses on two main aspects, namely preventive strategies and repressive strategies. The research method uses a qualitative approach with case studies, through in-depth interviews, observation, documentation, and interactive data analysis. The results show that the Panwascam's preventive strategies include socialization of election regulations, political education, and strengthening coordination with village officials and community leaders. This strategy has been proven to increase regulatory understanding among lower-level election organizers and public political awareness, especially first-time voters. Meanwhile, the repressive strategy is implemented through violation handling mechanisms, preparing legal recommendations, and summoning perpetrators and witnesses. Based on field findings, the Panwascam successfully handled one case of violation of ASN neutrality that was recommended to the Regency Bawaslu. This study concludes that the supervision of the Sinjai Borong Panwascam is relatively effective, although it still faces limited resources, low public legal literacy, and strong local political patronage. The results of this study provide a conceptual contribution to strengthening the community-based electoral supervision model, which integrates regulatory, educational, and collaborative aspects. They also serve as practical recommendations for improving the quality of electoral democracy at the local level.

The financial crisis experienced by PT Garuda Indonesia Tbk prompted the company to enter into a Debt Payment Suspension (PKPU) process as a legal measure to avoid bankruptcy and restructure its finances. The complexity of debt, liquidity pressures, and post-pandemic operational challenges have made PKPU a strategic instrument for obtaining debt payment deferrals and formulating a settlement plan that is acceptable to creditors. This study aims to analyze how the implementation of PKPU affects Garuda's rescue efforts from the threat of bankruptcy and assess the extent to which the debt restructuring resulting from PKPU in 2021–2023 effectively improves the company's financial condition. The method used is normative legal research with a legislative, conceptual, and case study approach to the homologation decision and Garuda Indonesia's official financial reports. The results of the study show that PKPU provides legal certainty for debtors and creditors through a collective postponement mechanism, and debt restructuring has been proven to significantly reduce the company's liabilities from around US$10.1 billion to around US$4.6 billion, while improving financial and operational stability in the short to medium term. In conclusion, PKPU serves as an effective corporate rescue instrument, while post-PKPU debt restructuring provides a strong foundation for Garuda Indonesia's financial recovery, although long-term sustainability still depends on the consistent implementation of the peace plan and the company's operational performance.

Early childhood (0–6 years) is a critical period in human development, often referred to as the golden age, during which all aspects of development, including language and vocabulary, grow rapidly. However, based on preliminary observations at TK Merpati, Simpang Sungai Rengas District, the vocabulary skills of children aged 4–5 years were still relatively low. This study aimed to examine the effectiveness of papercraft puppet media in improving the vocabulary skills of children aged 4–5 years at TK Merpati, Simpang Sungai Rengas District. The research employed a classroom action research design conducted in three cycles. The subjects consisted of 17 children aged 4–5 years. Data were collected through observation sheets, and data analysis was carried out by comparing the percentage of children’s vocabulary achievement before and after the implementation of the papercraft puppet media in each cycle. The results indicated a significant improvement in children’s vocabulary skills. In the pre-action stage, children’s achievement was categorized as Not Yet Developed (NYD) with a percentage of 30%. In Cycle I, the percentage increased to 50% (Beginning to Develop). In Cycle II, it further improved to 76% (Developed as Expected). In Cycle III, the results reached 95% (Very Well Developed). These findings demonstrate that papercraft puppet media is effective in enhancing vocabulary development in early childhood.

In the 21st century learning era that demands the integration of 4C skills and digital literacy, the textbook Akidah Akhlak Class IV MI based on the 2019 KMA 183 Curriculum needs to be evaluated for its suitability to be relevant in shaping students' Islamic character. This study aims to analyze the suitability of the book's content, presentation, language, and graphics according to BSNP standards, with a focus on the strengths of active learning and the weaknesses of technology integration such as QR codes and science-technology interconnections. The descriptive qualitative method through library research uses the 2020 Kemenag textbook by Subkhiaton Noor as primary data, supported by BSNP instruments and comparisons with other books. The results show that the book is very suitable overall: very good content suitability (accurate material, relevant KI-KD, supports 4C through discussion and reflection), good presentation (systematic structure, HOTS-LOTS, glossary), good language (communicative, appropriate to students' cognition), graphics pass with minor improvements in visual consistency, so it is effective for contextual learning even though it needs additional digital features.

The purpose of this study was to examine how problem-based mathematics learning affected the learning interest of 5- to 6-year-old students at the Ki Hajar Dewantara State Kindergarten in South Jakarta. To compare problem-based mathematics learning and conventional learning, this study used a quantitative method and a quasi-experimental design. Problem-based learning is intended to use mathematical problems in children's daily lives. Children in group B were divided into experimental and control groups. To collect data, structured observations were conducted on elements of children's interest in learning. These included enjoyment, focus, activity, and willingness to participate in learning activities. To determine the difference in the level of interest in learning between the two groups, the data obtained was analyzed statistically. The results showed that, compared to conventional learning, problem-based mathematics learning had a significant effect on increasing children's interest in learning. Children showed more enthusiasm, better concentration, active involvement in activities, and critical thinking skills in solving mathematical problems. The results showed that effective problem-based mathematics learning made learning meaningful, enjoyable, and appropriate for the characteristics of early childhood development.

The establishment of the age limit for children up to 18 years in Indonesian law is a normative instrument that aims to ensure legal certainty and child protection. This provision is adopted in various laws and regulations as a form of the state's commitment to fulfilling children's rights. However, in law enforcement practice, the application of this age limit often causes problems when faced with the dynamics of actual cases that reveal a discrepancy between the normative age and the social, psychological, and factual conditions of the child. This condition creates tension between the legal-formal approach that emphasizes legal certainty and the need for substantive justice oriented towards the best interests of the child. This study aims to analyze the problems of applying the age limit of 18 years in the context of actual cases and to examine how the tension between legal certainty and the reality of children is reflected in law enforcement practices in Indonesia. The research method used is normative legal research with a legislative and conceptual approach, as well as normative qualitative analysis. The results of the study show that the rigid application of the age limit for children has the potential to ignore the contextual aspects of children and give rise to inconsistencies in practice. Therefore, a more contextual legal approach is needed through strengthening the discretion of law enforcement officials and progressive interpretation by judges in order to achieve substantive justice and optimal protection for children.

Stunting remains one of the major chronic nutritional problems in Indonesia, including in Oesapa Village, Kelapa Lima District, Kupang City, East Nusa Tenggara Province. This condition is not only caused by inadequate nutritional intake but is also closely related to chronic infections resulting from poor hygiene and sanitation, particularly intestinal parasitic diseases. To reduce the risk of parasitic infections and improve children’s nutritional status, preventive efforts through education and health promotion are essential.This community service activity aimed to increase public awareness and knowledge, especially among parents and caregivers of stunted children, regarding the importance of maintaining hygiene and sanitation to prevent intestinal parasitic diseases. The methods used included participatory approaches such as interactive lectures, group discussions, and practical demonstrations of clean and healthy living behavior (PHBS), food hygiene, clean water management, and household waste disposal. Evaluation was conducted using pre-test and post-test instruments to measure changes in participants’ knowledge.The activities, carried out from May to September 2025 in Oesapa Village, showed a significant improvement in community understanding of hygiene and sanitation practices. Participants demonstrated greater commitment to maintaining environmental cleanliness and adopting healthier daily behaviors. Continuous educational efforts and multisectoral support are needed to help reduce the prevalence of stunting in the region

Puberty in girls is a developmental stage where sexual maturation occurs as a manifestation of reproductive ability, marked by the first menstruation (menarche), a form of primary sexual maturity in girls. The purpose of this study was to determine whether there is a relationship between nutritional status and maternal menarche history with early menarche in elementary school students in grades 4-6 at SDN 01 Nagrak Gunung Putri Bogor in September 2025. This research was a quantitative, observational analytical study using a cross-sectional approach. It was conducted at SDN 01 Nagrak Gunung Putri Bogor from August to September 2025 with a sample of 49 respondents. Univariate and bivariate data analysis used the Chi-Square Test.

The study concluded that there is a relationship between maternal nutritional status and menarche history with early menarche. It is recommended that SDN 01 Nagrak Gunung Putri Bogor collaborate with the nearest community health center and the Health College to conduct outreach activities on reproductive health.

In the learning process, educators often face challenges in helping students achieve optimal learning outcomes. One of the contributing factors is the dominance of teacher-centered learning models, which frequently leads to low student engagement and reduced motivation. This condition affects students’ curiosity, particularly in Science learning, which requires active participation and exploration. Therefore, innovative teaching materials are needed to encourage student involvement while simultaneously stimulating their curiosity. One alternative that can be utilized is the Student Worksheet (Lembar Kerja Peserta Didik/LKPD), which can be designed systematically and contextually to support active learning. This study aims to determine the effectiveness of using LKPD in enhancing students’ curiosity in Grade VII Science learning at SMPN 1 Sanrobone. The research employed a Classroom Action Research (CAR) approach carried out in two cycles, each consisting of planning, implementation, observation, and reflection stages. The findings indicate a significant increase in students’ curiosity after the implementation of LKPD, as shown by improvements in questioning behavior, interest in the material, and the ability to observe and explore scientific phenomena. Based on these results, it can be concluded that the use of LKPD is effective in fostering students’ curiosity and contributes to a more interactive and meaningful Science learning experience.
