This community service program aimed to improve teachers’ understanding and practical skills in preparing Classroom Action Research (CAR) proposals among senior high school teachers in Semarang City, Indonesia. Classroom Action Research is an essential component of teacher professional development, enabling educators to systematically identify classroom problems, implement pedagogical interventions, and evaluate learning improvement strategies. However, many teachers encounter difficulties in translating classroom challenges into structured research proposals. The program involved 22 teachers from public and private senior high schools in Semarang City and was implemented using a participatory and experiential learning approach integrating theoretical sessions, guided discussion, proposal-writing workshops, and direct mentoring. Training materials covered classroom problem identification, research cycles, proposal structure, formulation of objectives, intervention design, and indicators of success. Program effectiveness was evaluated through direct assessment of participants’ practical outputs. The success indicator was defined as a minimum of 90% of participants being able to prepare an initial classroom action research proposal draft correctly according to the provided guidelines. The results showed that the program successfully achieved its target, with 90.9% of participants able to produce an initial classroom action research proposal draft containing essential proposal components. Participants also demonstrated improved confidence and understanding regarding classroom-based research implementation. This program contributes a practical professional development model integrating research literacy enhancement and hands-on proposal writing practice to strengthen teachers’ reflective teaching and evidence-based instructional improvement capacity.

Tobacco use remains a significant public health issue in Indonesia. Adolescents are considered capable of making their own decisions, including the choice to smoke. According to the Global Adult Tobacco Survey (GATS) 2021, the smoking prevalence in Indonesia is 33.5%, equivalent to 68.8 million people. This study aims to analyze the factors influencing smoking behavior among adolescents. The results of this study emphasize the importance of greater attention and action to smoking prevention efforts among adolescents, especially among males and those in the older age group. The interventions focused on health education and raising awareness of the dangers of smoking which need to be enhanced, as well as involving family and schools to create a supportive environment therefore the adolescents can make healthier decisions. Furthermore, these results can serve as a basis for the development of more effective policies to address the issue of smoking among adolescents in Indonesia. The research employed a descriptive quantitative method with a cross-sectional design. A total of 5,181 respondents were selected using simple random sampling, and data were collected using a questionnaire. The findings reveal that daily smoking behavior among adolescents is still relatively high, with 11.7% of respondents smoking every day. The majority of respondents were male (70.78%), with the largest age groups being 15 years (21.3%) and 14 years (20.6%). Bivariate analysis using the Chi-Square test indicated a significant relationship between smoking behavior and both age and gender, with a p-value of 0.000 (p < 0.05). These results suggest that male adolescents and older age groups are more likely to engage in smoking behavior than their counterparts.

This study examines the dynamics of church music regulation implementation in the congregation of the Adventist Secondary School – Surya Nusantara Adventist University (SLA-UASN) Pematangsiantar (September 2022–December 2025). The goal is to describe the implementation of the regulation in worship practices, address challenges, reveal congregational responses, and align local practices with the views of Ellen G. White and official SDA documents. The research employed a qualitative descriptive approach with a case study method; data were collected through in-depth interviews with 16 informants, participant observation, and documentation studies, then analyzed thematically using source triangulation. The results indicate that the regulation originates from church regulations (SDA Church Guidelines) and local policies, but is disseminated orally, resulting in differing understandings. There is intergenerational tension between supporters of traditional music (hymnals) and contemporary music that has not been bridged dialogically. Resistance from music ministers arises from inconsistent implementation and minimal involvement in policy development. Communication between music leaders and ministers remains weak, with no regular evaluation forum, resulting in a continued decline in the quality of music worship. This study concludes that effective music regulation requires clear written documentation, structured intergenerational dialogue, ongoing music theology education, and inclusive and participatory pastoral leadership.

The method used was a descriptive quantitative approach with a one group pre-test post-test design involving 54 students as participants. The instrument used was a questionnaire administered before and after the educational session. The educational materials included the definition, types, impacts, and prevention efforts related to Bullying and child harassment in the school environment. The results showed an increase in students’ knowledge and awareness regarding the importance of preventing Bullying and child harassment in schools. Therefore, educational programs conducted through the KKN activity can be one of the efforts to create a safe and Bullying-free school environment.

This study aims to identify and explain language errors in a scientific journal article entitled "Analysis of Language Errors in Expository Texts on the Digital Platform 'Ruangguru', August 2024 Edition as a Reading Resource for High School Students," published in the Semantik Journal, Issue 3, Number 4. The method applied in this study is descriptive qualitative using a literature study approach. For data collection, observation and recording techniques were used, while data analysis was carried out using the content analysis method. The findings of this study revealed 27 language errors divided into five categories, including 12 spelling errors (typos) (44.4%), 5 word choice errors (18.5%), 4 punctuation errors (14.8%), as well as ineffective sentence structure errors and errors in the bibliography (3 each) (11.1%). The causes of these errors include minimal editing process, inadequate understanding of PUEBI (Indonesian Standards for Ethics and Education), and inaccuracies from the author. This study shows that articles analyzing language errors still contain errors, so there is a need for improvements in the quality of editing by the author and the journal's editorial team.

This study aims to analyze the extent of the effect of honey bee pollen supplementation on increasing appetite and body weight in anemic children. The type of research used in this study is an experimental study with a pre- and post-test one-group design. The research sample consisted of 52 anemic fourth- and fifth-grade elementary school students. The average total food intake (Yellow Rice) showed a significant result (P=0.000), increasing from 241.40±94.334 g to 354.94±122.57 g after the final measurement of ad libitum appetite. The average body weight also showed a significant result (P=0.00), with a mean of 23.59±5.29 kg at pre-test and rising to 24.65±5.58 kg at post-test. The Z-Score calculation for weight-for-age based on the WHO NCHS reference showed a non-significant result: P=0.0180 (0.01±0.04) at pre-test and 0.03±0.08 at post-test. Based on the 24-hour recall analysis over two days, a significant result was obtained (P=0.000), with total energy intake of elementary school students increasing from an average of 1,594±420.17 kcal before intervention to 2,070.2±491.77 kcal after two months of intervention. After statistical testing (Paired T-Test), a P-value of 0.00 (<0.05) was obtained. It can be concluded that the administration of honey bee pollen for 8 weeks at a dose of 25 grams per day significantly increased appetite and body weight in anemic elementary school children.

Student character building is an important goal in the education system, particularly in Christian Religious Education (CRE) which emphasizes not only cognitive aspects but also the development of moral and spiritual values. However, various character issues such as low discipline, responsibility, and social awareness remain challenges in the school environment. Therefore, a learning strategy is needed that can integrate Biblical values contextually into the educational process. This study aims to analyze learning strategies based on Matthew 11:28–30 in shaping student character at SMP Negeri 1 Moro’o, West Nias Regency. This study uses a qualitative approach with descriptive methods. Data were collected through observation, in-depth interviews, and documentation involving Christian Religious Education teachers and students. The results of the study indicate that the values contained in Matthew 11:28–30, such as love, humility, gentleness, and peace of mind, can be implemented through contextual learning strategies, teacher role models, and reflective learning. The implementation of these strategies contributes to student character building, especially in improving attitudes of discipline, responsibility, and concern for others. The novelty of this research lies in the development of a learning strategy framework based on theological analysis of Matthew 11:28–30 which is practically integrated into Christian Religious Education learning to shape students' character.

School snacks are one of the food sources commonly consumed by elementary school children; however, they are at risk of microbiological contamination if not properly managed. One of the pathogenic bacteria that can contaminate food is Salmonella, which can cause diarrheal disease. This study aimed to analyze hygiene and sanitation factors of food handlers on Salmonella bacterial contamination in pentol snacks at elementary schools in Palang District, Tuban Regency. This study used an observational analytic design with a cross-sectional approach. The sample consisted of 20 pentol vendors and 20 pentol snack samples. Data were collected through observation using a hygiene and sanitation checklist and laboratory examination to detect the presence of Salmonella bacteria. Data analysis was initially planned using the Chi-square test; however, due to homogeneous results, the analysis was conducted descriptively. The results showed that most vendors had good hygiene and sanitation (85%) and sufficient (15%). Laboratory examination results showed that all pentol snack samples (100%) were negative for Salmonella bacteria. In conclusion, pentol snacks at elementary schools in Palang District were microbiologically safe from Salmonella contamination.

The research in this paper aims to explore the concepts and principles of the educational environment from the perspective of the Qur'an and Hadith using a tafsir tarbawi (educational exegesis) approach. The developmental dynamics of human potential, both spiritual and intellectual, do not occur in a vacuum but are heavily influenced by environmental factors (educational ecology). By employing textual, thematic, and contextual analysis methods on several key verses such as QS. Al-Alaq: 1-5, QS. At-Tahrim: 6, QS. Luqman: 13-19, QS. Al-Kahfi: 66-70, and QS. Al-Hujurat: 13 this study maps the Islamic educational ecosystem into several primary domains. The results of the analysis indicate that the Qur'an constructs the educational environment as an integrative macro-systemic unity, comprising the domestic family environment (as a fortress for moral and creedal protection), the formal academic school/pesantren environment (as a space for teacher-student etiquette and ethics), and the socio-communal environment (as an arena for egalitarian multicultural inclusivity). Furthermore, this study formulates five fundamental paradigms of Islamic educational ecology: the integralistic, tawhid (monotheistic), humanistic-egalitarian, gradual-systemic, and transformational-emancipatory paradigms. This theoretical reconstruction corrects Western secular empiricism while simultaneously providing a holistic foundation for educators in managing an educational environment that aligns with divine revelation values and the demands of modern civilization.

This community service program aims to empower students. The lack of digital business literacy and knowledge about Islamic entrepreneurship in Islamic-based schools, as well as the application of sharia business principles, are the main drivers of this program. The activity implementation technique uses the Participatory Action Research (PAR) methodology. Problem identification, needs analysis, preparation of materials and instruments, pre-testing, training in Islamic business ethics and entrepreneurship theory, digital business practices, mentoring, post-testing, and program evaluation are some of the steps included in the activity. A total of 60 12th-grade students and ten instructors participated in this activity. The results showed that students' knowledge of sharia-based digital business, digital marketing skills, and entrepreneurial drive all increased. Student interest in starting a business increased by 78%, and participants' understanding of digital literacy increased by 85%. Furthermore, the program successfully instilled the ideals of Islamic entrepreneurship, such as accountability, honesty, and trustworthiness, as well as the prohibition of usury in digital business operations. In addition to encouraging the development of an Islamic digital business community within the educational environment, this community service program helps students develop personalities with noble morals, creativity, and adaptability.

This study aims to examine the authority of Islamic Education teachers as a form of moral capital in shaping character education among elementary school students. The research employed a qualitative method using a case study approach at SD Negeri 104267 Pegajahan. The primary subjects of the study were Islamic Religious Education (PAI) teachers, while the informants consisted of students, fellow teachers, and the school principal. Data were collected through observations, in-depth interviews, and documentation studies, then analyzed thematically to identify patterns related to teacher authority and character formation. The findings indicate that the authority of Islamic Religious Education teachers functions as a moral force recognized and respected by students, making it an important asset in the internalization of character values. This authority was formed through exemplary behavior, consistency in attitudes, and the establishment of humanistic pedagogical relationships between teachers and students. Through these qualities, teachers became moral role models who positively influenced students’ character development both inside and outside the classroom. The study concludes that strengthening teacher authority as moral capital is an effective strategy for realizing authentic, meaningful, and sustainable character education in elementary schools, as teacher authority should not only be viewed institutionally but also as a moral resource that significantly contributes to students’ personal and social development.

This research aims to classify students’ lifestyles using the K-Nearest Neighbors (KNN) algorithm. The dataset consists of 392 high school students obtained from Kaggle, with key attributes including study hours, social media usage, Netflix viewing duration, attendance, sleep quality, internet quality, mental health, and extracurricular activities. KNN was chosen for its simplicity in distance-based classification, measured using Euclidean Distance.
