Background: Adolescents are a group vulnerable to various reproductive health issues, including sexually transmitted infections (STIs), due to limited knowledge and exposure to inaccurate information. Health education serves as a promotive and preventive measure to enhance adolescents' understanding of STI prevention. Purpose: To provide effective health education aimed at increasing adolescents' knowledge and awareness regarding STI prevention. Method: This community service activity was conducted at KP Vocational high school Baleendah, Bandung Regency, West Java, on February 11, 2026. The activity aimed to impart knowledge and understanding regarding STIs and their prevention among adolescents. Thirty-three students participated as respondents. Knowledge levels were measured using a Google Forms questionnaire administered before (pre-test) and after (post-test) the educational session. The questionnaire covered the definition of STIs, types of STIs, modes of transmission, signs and symptoms, impacts on reproductive health, and prevention strategies. Evaluation involved analyzing questionnaire scores using a one-group pre-test and post-test design to measure changes in respondents' knowledge levels before and after the intervention. Results: The results showed that the mean age of respondents was 15.9 years (standard deviation ±0.63 years), with the majority (20 respondents or 60.36%) being 16 years old. Regarding gender, there were 12 male respondents (36.4%) and 21 female respondents (63.6%). Knowledge scores prior to the educational activity yielded a mean of 11.03 points (standard deviation ±2.81 points) within a range of 5–15 points, whereas scores following the activity showed a mean of 13.48 points (standard deviation ±1.02 points) within a range of 9–15 points. Conclusion: The community service activity, consisting of health education on the prevention of sexually transmitted diseases (STDs), successfully increased adolescents' knowledge regarding reproductive health and STD prevention measures. This increased knowledge fostered self-motivation and encouraged the adoption of healthier, more responsible behaviors concerning reproductive health. Suggestion: Schools are encouraged to integrate reproductive health education into their regular student development programs. Furthermore, future community service initiatives could employ more interactive methods—such as peer education, the establishment of adolescent health cadres, or the use of digital media—to strengthen the sustainability of reproductive health education programs.

This study aims to identify forms of social entrepreneurship among Social Studies Education students, examine the application of Sundanese cultural values, analyze the supporting and inhibiting factors, and formulate a social entrepreneurship model based on local wisdom. A qualitative approach with a multiple-case study design was employed. The research was conducted at three universities—Universitas Bale Bandung, Institut Pendidikan Indonesia, and Universitas Tazkia—using observations, document analysis, focus group discussions (FGDs), and in-depth interviews with 29 informants, including students, faculty members, program administrators, and community partners. Data were analyzed interactively through data condensation, data display, and conclusion drawing. The findings indicate that student social entrepreneurship manifests in three main forms: businesses based on local potential, community cooperatives, and digital social movements. Sundanese cultural values, including Silih Asah, Silih Asih, Silih Asuh, Sauyunan, and Sabilulungan, as well as the character traits of Cageur, Bageur, Bener, Pinter, and Singer, were found to be well integrated into entrepreneurial practices. Institutional support and social capital emerged as the primary enabling factors, whereas limited financial capital and business literacy constituted the major barriers. This study resulted in the NISSE Model (Sundanese Values–Social Sciences–Social Entrepreneurship), a holistic framework that integrates cultural inputs, the pedagogical processes of Social Studies Education, student competencies, and community transformation. Theoretically, the model contributes to the theory of indigenous entrepreneurship by demonstrating how local wisdom can function as an operational principle shaping business ethics, collaborative decision-making, and altruistic orientations. Practically, the NISSE Model provides a curriculum framework for local-wisdom-based entrepreneurship that may be adapted to diverse cultural contexts globally.
Background: Gastritis is a common digestive health problem among productive age groups, including farmers, due to irregular eating patterns and inappropriate food choices. Farmers' physically demanding work activities and long working hours often lead to delayed mealtimes, increasing the risk of gastritis. Purpose: To increase farmers' knowledge about healthy eating habits as a means of preventing gastritis. Method: This community service activity was conducted on January 18th in Mekarsari Village, Cimaung District, involving 10 farmers as respondents. This community service activity used an educational and participatory approach based on community nursing, oriented towards increasing knowledge and empowering farmers in gastritis prevention efforts through the implementation of healthy eating habits. The extension material was delivered through interactive lectures supported by posters and leaflets, combined with discussions and questions and answers. Respondents' knowledge levels were measured using questionnaires administered before and after the educational activity (pre-test) and after the educational activity (post-test). A descriptive qualitative evaluation was conducted by comparing changes in respondents' knowledge levels between before and after the educational activity. Results: The average age of respondents was 39.2 years with a standard deviation of ±8.79 years. Most respondents were aged 40–49 years (40.0%). 50.0% of respondents were male and 50.0% were female. The educational level of respondents was 40.0% elementary school graduates, 40.0% junior high school graduates, and 20.0% high school graduates. The majority of respondents had worked as farmers for >10 years (6 respondents) and most respondents had a history of stomach complaints (8 respondents) (80.0%). There was an increase in respondents' knowledge about diet and gastritis prevention to 80.0% (post-test) in the good category from 60.0% before the educational activity (pre-test). Conclusion: The Community Service (PKM) activity, which provided education on healthy eating patterns for farmers, effectively increased participants' knowledge of healthy eating principles and gastritis prevention efforts. This activity also provided relevant benefits that can be continued and developed as a promotional and preventive program in the community, particularly for groups of farmers at risk of gastric health problems, thereby contributing to improving community health. Suggestion: It is hoped that the community will apply and share health information related to the knowledge gained regarding regular mealtimes and selecting safe foods for the stomach in their daily lives. Community Health Centers are also expected to collaborate with relevant parties to ensure the sustainability of community-based health education programs as a promotional and preventive effort, particularly in preventing gastritis. Keywords: Health education; Gastritis; Community health; Farmers; Healthy eating patterns Pendahuluan: Gastritis merupakan salah satu masalah kesehatan saluran cerna yang sering dialami oleh kelompok usia produktif, termasuk petani, akibat pola makan yang tidak teratur dan pemilihan makanan yang kurang sesuai. Aktivitas kerja petani yang menuntut fisik tinggi dan waktu kerja panjang sering kali menyebabkan keterlambatan waktu makan sehingga meningkatkan risiko terjadinya gastritis. Tujuan: Meningkatkan pengetahuan petani mengenai pola makan sehat sebagai upaya pencegahan gastritis. Metode: Kegiatan pengabdian kepada masyarakat ini dilaksanakan pada tanggal 18 Januari di Desa Mekarsari, Kecamatan Cimaung, dengan melibatkan 10 orang petani sebagai responden. Kegiatan pengabdian kepada masyarakat ini dilaksanakan dengan pendekatan edukatif dan partisipatif berbasis keperawatan komunitas, yang berorientasi pada peningkatan pengetahuan serta pemberdayaan petani dalam upaya pencegahan gastritis melalui penerapan pola makan sehat. Materi penyuluhan disampaikan melalui ceramah interaktif yang dibantu media poster dan leaflet serta dikombinasikan dengan diskusi dan tanya-jawab. Tingkat pengetahuan responden diukur menggunakan kuesioner yang dilakukan sebelum kegiatan edukasi (pre-test) dan sesudah kegiatan edukasi (post-test). Evaluasi secara deskriptif kualitatif dengan membandingkan perubahan tingkat pengeteahuan responden antara sebelum kegiatan edukasi dengan sesudah kegiatan edukasi. Hasil: Menunjukkan bahwa rata-rata usia responden adalah 39.2 tahun dengan standar deviasi ±8.79 tahun, sebagian besar responden berusia 40–49 tahun sebesar 40.0%. Responden yang berjenis kelamin laki-laki sebesar 50.0% dan berjenis kelamin perempuan juga sebesar 50.0%.

Mayoritas responden memiliki status pekerjaan sebagai petani selama >10 tahun yaitu sebesar 60.0%, dan sebagian besar responden memiliki riwayat keluhan pada lambungnya yaitu sebanyak 8 responden (80.0%). Terdapat peningkatan pengetahuan responden tentang pola makan dan pencegahan gastritis dalam kategori baik menjadi sebesar 80.0% (post-test) dari sebesar 60.0% sebelum kegiatan edukasi (pre-test). Simpulan: Kegiatan Pengabdian kepada Masyarakat (PKM) berupa edukasi pola makan sehat pada petani secara efektif memberikan peningkatan pengetahuan peserta mengenai prinsip pola makan sehat dan upaya pencegahan gastritis. Kegiatan ini juga memberikan manfaat yang relevan untuk dilanjutkan dan dikembangkan sebagai program promotif dan preventif di masyarakat, khususnya pada kelompok petani dengan risiko gangguan kesehatan lambung sehingga berkontribusi dalam meningkatkan derajat kesehatan komunitas. Saran: Diharapkan kepada masyarakat dapat menerapkan dan saling berbagi informasi kesehatan terkait pengetahuan yang telah diperoleh mengenai keteraturan waktu makan dan pemilihan jenis makanan yang aman bagi lambung dalam kehidupan sehari-hari. Diharapkan juga kepada Puskesmas untuk melakukan kolaborasi dengan pihak terkait dalam menjamin program edukasi kesehatan berbasis komunitas dapat berjalan secara berkelanjutan sebagai upaya promotif dan preventif, khususnya dalam pencegahan penyakit gastritis.
This research was conducted in Kecamatan Majalaya. Kecamatan Majalaya is chosen as locus of this re- search because of its uniquenesses. One of its uniquenesses is a diversity of communities that have experienced acculturation and language. The data examined in this study amounted to one hundred and seven vocabularies. The method used in this study is descriptive, i.e. a method that aims to create a portrait or depiction on data, at- tribute, and relationships of phenomena under study in a systematic, factual, and accurate way. Thus, the expected result is to establish the description of vocabulary in form of a portrait or disclosure as it is. The purpose of this study is to identify the development of the vocabularies in Bandung’s geographical dialect, that is the frontier of lulugu Sundanese (formal language) and Bandung Sundanese (informal language). The results showed that there was a wide difference between Majalaya northern dialect with South Majalaya in phonologic-morphophonemic, such as language symptoms of metathesis, protesis, epentesis, aperesis, syncope, and apocope. Beside that, there are morphological differences in repeated words (reduplication) and compound (compositum), while in semantical differences, there may be a completely different form, but the inherent meaning is still the same.
SQL Injection (SQLi) and Cross-Site Scripting (XSS) remain severe threats to web application security, particularly as attackers employ increasingly sophisticated obfuscation techniques to bypass conventional detection systems. This research constructs a machine learning framework using ensemble learning — specifically combining Random Forest and XGBoost — integrated with character-level n-gram feature extraction. The methodology involved rigorous data curation of a large-scale dataset, refining 156,636 raw samples into 151,783 unique entries to ensure high-quality training data. By extracting 10,000 character-level n-gram features, the model captures the intricate structural patterns of complex and obfuscated payloads. Experimental results show consistent and measurable performance: the proposed ensemble model achieved an overall accuracy of 99.67%. Stability was confirmed through a 5-fold cross-validation process, yielding a mean accuracy of 99.64% and a standard deviation of 0.0003. These findings are reinforced by ROC AUC scores of 1.0000 for XSS and 0.9999 for SQLi, indicating near-perfect discriminative capability. The combination of character-level representation and ensemble learning produces a precise and resilient solution for safeguarding modern web environments against dynamic and evolving cyber threats.
