Malware represents an evolving cybersecurity threat that demands more effective detection methods. Conventional signature-based detection systems have limitations in identifying new variants, driving the development of deep learning-based approaches. This research implements and evaluates four variants of the YOLOv11 algorithm (n, s, m, l) for malware classification based on visual image representation. The dataset consists of 22,056 malware and benign images, divided into 70% training, 15% validation, and 15% testing across 8 classes (adware, backdoor, benign, downloader, spyware, trojan, virus, worm). Each model was trained for 100 epochs with batch size 32 using Google Colab with GPU support. Results demonstrate that all variants achieve high accuracy (97.8%-98.1%) with YOLOv11m as the best performer (98.1%). YOLOv11n offers optimal balance between accuracy (97.9%) and efficiency (1.5M parameters, 0.3 ms/img inference) ideal for real-time applications. This research surpasses previous methods such as K-NN (97.18%) and hybrid CNN (96.55%) with superior inference speed (0.3-0.9 ms/img vs tens to hundreds of ms/img), proving the effectiveness of YOLOv11 for fast, accurate, and scalable malware detection.

This study investigates the implementation of the Gradient Boosting Machine (GBM) algorithm for network intrusion detection using the CICIDS2017 dataset within the CRISP-DM framework. The process encompasses Business Understanding, Data Understanding, and Data Preparation including data cleaning, categorical feature encoding, normalization, and data split (80 % training, 20 % testing). In the Modeling phase, GBM Hyperparameters (learning_rate = 0.1; max_depth = 5; n_estimators = 150) were optimized via Grid Search with 2-fold Cross Validation, and F1-Score  was selected as the primary metric due to class imbalance. Evaluation on the test set yielded accuracy of 99.99 %, precision of 100 %, Recall of 99.98 %, and F1-Score  of 99.99 %, demonstrating exceptional detection capability with minimal false negatives and false positives. Compared to previous studies, this GBM model outperforms in accuracy and stability without overfitting. These findings confirm GBM’s effectiveness for modern Intrusion Detection Systems and its suitability for Deployment in resource-constrained operational environments.

Background: Adenoid hypertrophy is a condition characterized by enlargement of the adenoid tissue which can cause nasopharyngeal obstruction and potentially affect the function of the Eustachian tube. Dysfunction of the Eustachian tube may disrupt middle ear ventilation and increase the risk of otitis media. The degree of adenoid hypertrophy can be objectively assessed using a lateral nasopharyngeal radiograph by calculating the adenoid–nasopharyngeal ratio (A/N ratio). Objective: This study aimed to determine the relationship between adenoid hypertrophy based on the adenoid–nasopharyngeal ratio and the incidence of otitis media. Methods: This study was a quantitative research with an analytic observational design using a cross-sectional approach. Data were obtained from the medical records of patients with adenoid hypertrophy who underwent lateral nasopharyngeal radiographic examination at RSI Purwokerto from 2022 to 2025. The sample consisted of 31 patients who met the inclusion and exclusion criteria. Data analysis was performed using the Spearman correlation test because the data were not normally distributed based on the Shapiro–Wilk test. Results: The results showed that most of the subjects were male (17 subjects, 54.8%) and female (14 subjects, 45.2%). The median age of the subjects was 7 years with an age range of 4–9 years. The median adenoid–nasopharyngeal ratio was 0.90 with a range of 0.68–0.99. Otitis media was found in 11 subjects (35,5%), while 20 subjects (64,5%) did not experience otitis media. The Spearman correlation test showed a correlation coefficient of r = 0.015 with a p-value of 0.936 (p > 0.05), indicating that there was no significant relationship between the adenoid–nasopharyngeal ratio and the incidence of otitis media. Conclusion: There was no statistically significant relationship between adenoid hypertrophy based on the adenoid–nasopharyngeal ratio and the incidence of otitis media.

The rapid growth of e-commerce among university students has provided greater convenience in conducting digital transactions. However, it has also created various challenges, including online fraud, discrepancies between advertised and delivered products, delayed shipments, and limited understanding of consumer rights and dispute resolution mechanisms. This community service program aimed to enhance legal literacy and increase students’ awareness of consumer protection in electronic transactions, particularly within the Faculty of Teacher Training and Education (FKIP) of Yapis University Papua. The program employed an educational-participatory approach through counseling sessions, interactive discussions, case simulations, and participant comprehension evaluations. The materials covered consumer rights and obligations, common violations in electronic transactions, complaint procedures on e-commerce platforms, and non-litigation dispute resolution mechanisms. The results demonstrated a significant improvement in students’ understanding of consumer protection laws, their ability to identify violations of consumer rights, and their knowledge of appropriate actions when disputes arise in online shopping transactions. Furthermore, participants showed strong engagement throughout the activities and were able to apply their knowledge effectively during case simulations. The program contributed to the development of more critical, informed, responsible, and legally aware digital consumers who are better prepared to engage safely and confidently in e-commerce activities.

The Integrated Primary Care Posyandu (ILP) program requires cadres to assume a much broader role compared to conventional Posyandu services. In the working area of Puskesmas Penusupan, ILP achievement reached only 20% in 2025, while merely 25 out of 225 cadres (11%) had received related training. This condition indicates that cadre readiness needs to be examined more comprehensively before the program can be implemented optimally. This study aimed to analyze the factors associated with the readiness of ILP Posyandu cadres using a descriptive-analytic method with a cross-sectional approach. The study involved 144 cadres selected proportionally from a population of 225 using the Slovin formula. Data were collected through structured interviews using a validated questionnaire and analyzed using univariate, bivariate (Spearman Rank), and multivariate (ordinal logistic regression) analyses. The results showed that among the eight variables examined, only skills (r = 0.171; p = 0.040) and resource availability (r = 0.225; p = 0.007) were significantly associated with cadre readiness. In the multivariate analysis, resource availability emerged as the most influential factor with an OR = 2.839 (95% CI: 1.311–6.149), indicating that cadres supported by adequate resources were 2.8 times more likely to demonstrate good readiness. In conclusion, resource availability was identified as the dominant factor associated with the readiness of ILP Posyandu cadres in the working area of Puskesmas Penusupan. Therefore, improving the availability of facilities and infrastructure, providing practice-based training, and strengthening operational support should become priority programs in the future.

Chronic rhinosinusitis (CRS) is a long-term inflammatory condition affecting the nasal mucosa and paranasal sinuses, which significantly impacts patients’ quality of life due to persistent and recurrent symptoms. Limited epidemiological data regarding CRS are available in Central Kalimantan, particularly at RSUD dr. Doris Sylvanus in Palangka Raya, prompting this study to determine its prevalence and patient distribution characteristics. This research employed a quantitative descriptive design with a cross-sectional approach. Data were collected from medical records of patients diagnosed with CRS in 2023 and 2024. Univariate analysis was conducted, and results were presented in tables and diagrams illustrating frequency distributions by year, gender, age, and main complaints. The findings showed a total of 118 CRS patients, with 53 cases in 2023 and 65 cases in 2024. The prevalence of CRS increased from 4.91% in 2023 to 10.83% in 2024. Based on gender, males accounted for 50.8% (60 patients), while females represented 49.2% (58 patients). The age group most affected was 46–55 years (31%), indicating a predominance among individuals of productive age. Nasal congestion was the most frequent primary complaint, reported by 35% of patients. The study concludes that the prevalence of CRS at RSUD dr. Doris Sylvanus increased notably from 2023 to 2024, with a slightly higher incidence among males in the productive age group. These findings highlight the need for enhanced preventive measures and early diagnosis to manage CRS more effectively in the local population.

Diabetes Mellitus is a non-communicable disease with an increasing prevalence and has become a major public health concern globally and nationally. The incidence of diabetes mellitus is influenced by various individual and environmental factors. This study aimed to analyze the relationship between age, gender, and residential proximity to landfill areas and the incidence of diabetes mellitus in Bendosari District. A quantitative analytic observational design with a cross-sectional approach was employed. The study population consisted of 1,890 patient visit records recorded in the Management Information System of Bendosari Public Health Center in 2025. A total of 363 respondents were selected using proportionate stratified random sampling. Data were analyzed through univariate analysis, bivariate analysis using the Chi-Square test, and multivariate analysis using multiple logistic regression. The findings showed that age was significantly associated with diabetes mellitus incidence (p=0.000; OR=79.790; 95% CI=53.511–118.974). Gender was also significantly related to diabetes mellitus incidence (p=0.000; OR=0.298; 95% CI=0.203–0.435), indicating that females had a higher risk than males. In contrast, residential proximity to landfill areas was not significantly associated with diabetes mellitus incidence (p=0.308; OR=1.247; 95% CI=0.439–3.540). Multivariate analysis revealed that age and gender were the dominant factors influencing diabetes mellitus incidence, with the model explaining 56.1% of the variation. The study concludes that age and gender are significant determinants of diabetes mellitus incidence, whereas residential proximity to landfill areas has not been proven to significantly affect its occurrence.

Tuberculosis (TBC) in children remains a serious public health problem in Indonesia, with the 0–14 age group accounting for 16.2% of total notified cases in 2024. The uneven distribution of cases across provinces is thought to be influenced by various social determinants, yet spatial studies specifically on childhood TBC at the national level remain scarce. This study aimed to analyze the spatial pattern of childhood tuberculosis cases and social determinants in Indonesia in 2024 using a spatial ecological design across 38 provinces. Analysis included descriptive statistics, thematic mapping using QGIS, Moran's I test, and Local Indicator of Spatial Association (LISA) with queen contiguity weighting matrix. Results showed a strong positive spatial autocorrelation with a Moran's I value of 0.612. High-high clusters were identified in DKI Jakarta, Central Java, Banten, and West Java, which simultaneously recorded high population density and low primary healthcare ratios. Territory-based interventions should be prioritized in these hotspot provinces.

Conclusion: The Healthy Teen School program effectively improved adolescent nutrition knowledge and behavior.

A balanced diet is a daily dietary pattern that contains nutrients in types and amounts appropriate to the body's needs. Knowledge of balanced nutrition and healthy eating habits is an important factor in preventing nutritional problems among adolescents. A lack of understanding regarding appropriate food choices can lead to unhealthy eating behaviors. Therefore, nutrition education is needed to improve students’ knowledge and awareness of the importance of implementing a balanced diet in daily life. This counseling activity aimed to increase students’ knowledge regarding balanced dietary patterns. The activity was conducted on June 4, 2025, at State Junior High School 5 Kendari and involved 30 seventh-grade students as respondents. The counseling methods included lectures using PowerPoint media, an ice-breaking session in the form of the WHO six-step handwashing simulation, question-and-answer sessions, and interactive quizzes. Evaluation was carried out using pre-tests and post-tests to measure students’ knowledge levels before and after the counseling activity. The results showed an increase in the mean knowledge score from 68.40 in the pre-test to 89.67 in the post-test. The paired t-test analysis showed a Sig. (2-tailed) value of 0.000 (p < 0.05), indicating a significant difference between pre-test and post-test results. In addition, students gave positive responses to the counseling activity, stating that the material was interesting, easy to understand, and enjoyable. These findings indicate that balanced diet counseling was effective in improving students’ knowledge regarding the implementation of healthy eating habits in daily life.

The improvement of village road infrastructure plays an important role in enhancing community mobility and supporting local socioeconomic development. This study aims to analyze changes in mobility conditions before and after road improvement, explore community perceptions and experiences, identify changes in activity and economic patterns, and examine factors that support or hinder mobility optimization in Trayeman Village, Slawi District, Tegal Regency. A mixed-method approach was employed involving 98 respondents selected from a population of 5,229 residents using the Slovin formula with a 10% margin of error, along with 15 key informants for qualitative data collection. Data were gathered through observations, in-depth interviews, documentation studies, and Likert-scale questionnaires. Quantitative data were analyzed descriptively, while qualitative data were examined using the Miles and Huberman interactive analysis model. The findings indicate that road improvement has significantly enhanced community mobility, with an overall mean score of 3.89, categorized as high. Access to services recorded the highest score (4.06), followed by economic mobility (4.00) and social mobility (3.99). Community perceptions were largely positive, viewing the improved road as a catalyst for development and improved accessibility. Road improvement also encouraged broader economic opportunities, lower transportation costs, business growth, and increased income. Supporting factors included private vehicle ownership and supportive village policies, whereas high fuel prices, limited transportation options, and uneven local road conditions remained major challenges. Further improvements in supporting infrastructure and transportation services are recommended to maximize mobility benefits.

This study aims to develop and evaluate the feasibility of Teknoran, a website-based digital learning medium developed through the Canva application for the Office Technology subject in Grade X at SMKN 31 Jakarta.

Transportation plays an important role in supporting community mobility and enhancing socio-economic activities in urban areas. The increasing population growth and community activities in Sorong City have led to a higher demand for transportation modes. This study aims to identify the characteristics of transportation users in Kota Sorong and to analyze the probability of selecting different transportation modes using the Multinomial Logit (MNL) method. A quantitative approach was employed in this research. Questionnaires were distributed to 225 transportation users in Sorong City. The variables analyzed included gender, age, occupation, income, trip purpose, travel frequency, and reasons for choosing a transportation mode. The data were analyzed using multinomial logistic regression with SPSS software. The results indicate that transportation mode choice is influenced not only by socio-economic factors, but also by showed that income, trip purpose, travel frequency, and reasons for choosing the mode significantly influenced transportation mode choice, while gender, age, and occupation did not have significant effects. The probability analysis indicated that private vehicles had the highest probability of selection at 89.63%, followed by online transportation at 9.96%, and conventional motorcycle taxis at 0.41%. These findings imply that socio-economic and travel behavior factors strongly influence transportation mode preferences in Sorong City and may serve as a reference for future urban transportation planning and policy development.

Medical students need to take the Competence test as Doctor Profession Program (UKMPPD) to be passed and earned their medical profession. Exams are one of the most common stressors experienced by medical students and the body will respond to these stressors in the form of feelings of depression or anxiety. Anxiety and depression itself can affect student performance during exam preparation. The purpose of this study was to determine the relationship between anxiety and depression on the preparation of the Professional Doctoral Program Competency Test (UKMPPD) for students of the Faculty of Medicine, University of Pattimura. The method used is quantitative analysis with cross sectional research design and total sampling technique. The sample is all the student population of the Faculty of Medicine, University of Pattimura who meet the inclusion and exclusion criteria, totaling 90 respondents. The results showed that the majority of respondents experienced mild anxiety symptoms, which is 37% during the CBT exam and 34% during the OSCE exam. The majority of respondents also did not experience depression, which is 68% during the CBT and 70% during the OSCE and the majority had an optimal level of preparation for UKMPPD, which is 63% during the CBT and 64% during the OSCE. Data analysis using the chi square test showed a significant relationship between anxiety symptom and the level of preparation for UKMPPD both CBT (p=0.030) and OSCE (p=0.012). There was no significant relationship between depression symptom and the level of preparation for UKMPPD for both CBT (p=0.123) and OSCE (p=0.07). It can be concluded that there is a significant relationship between anxiety and preparation for UKMPPD, but there is no significant relationship between depression and preparation for UKMPPD.

Diabetes Mellitus Type II is a chronic metabolic disease characterized by elevated blood glucose levels due to insulin resistance and impaired insulin secretion. Globally, the number of people with diabetes in 2024 is estimated to reach 800 million, with more than 95% being Type II Diabetes Mellitus. At RSUD Prof. M. Yamin, SH Pariaman in 2025, there were 189 recorded cases of Type II Diabetes Mellitus without complications. The purpose of this scientific paper is to provide nursing care to a patient with Type II Diabetes Mellitus in the Internal Medicine Ward of RSUD Prof. M. Yamin, SH Pariaman. The method used is a case study with a nursing process approach, including observation, interviews, physical examination, and data collection from medical records. This study was conducted in the internal ward for 5 days, from February 6, 2026 to February 10, 2026, with the subject Mrs. N. The assessment results identified nine nursing problems: unstable blood glucose levels, acute pain, impaired skin/tissue integrity, ineffective peripheral perfusion, impaired physical mobility, sleep pattern disturbance, fatigue, risk of infection, and risk of nutritional deficit. The evaluation after 5 days of nursing care showed that five diagnoses were resolved, namely unstable blood glucose levels, ineffective peripheral perfusion, fatigue, risk of infection, and risk of nutritional deficit. Meanwhile, the other four diagnoses were not fully resolved but showed improvement. It is expected that the patient and family will maintain adherence to a healthy lifestyle, therapy, diet, and regular follow-up in order to prevent complications.

This community service activity aims to improve the community’s legal understanding and awareness through outreach on the National Criminal Code (KUHP) in Waisarisa Village, West Kairatu Subdistrict, West Seram Regency. The issues identified include the community’s limited understanding of the provisions of the New Criminal Code and a lack of legal awareness in daily life. The method used in this activity was a quantitative descriptive approach with a one-group pre-test and post-test design. Data collection was conducted through pre-tests, post-tests, and observations of 46 respondents who participated in the dissemination activity. The results of the activity showed an increase in the community’s legal understanding and awareness after participating in the outreach. The average pre-test score of 68.48% increased to 100% on the post-test, representing a 46.03% increase. The most significant improvement occurred in the indicators of understanding of the new Criminal Code and community legal awareness, each of which increased by 96%. These results indicate that legal outreach activities using an educational and participatory approach are effective in improving the community’s legal literacy. It is hoped that this initiative will foster a culture of legal awareness and enhance the community’s compliance with legal regulations in social life.

The enactment of Law Number 1 of 2023 concerning the Criminal Code (KUHP) has brought a fundamental paradigm reconstruction to the Indonesian criminal justice system through the explicit recognition of the "living law" (hukum yang hidup di masyarakat). This study aims to analyze the legal standing of living law within the Indonesian legal system and examine the juridical and sociological implications of integrating these unwritten norms from the perspective of Article 2 of Law Number 1 of 2023. The research method employed is normative legal research with a statutory approach. The results indicate that the positioning of living law holds a strategic standing rooted in Article 18B paragraph (2) of the 1945 Constitution of the Republic of Indonesia and is further reinforced by the Constitutional Court Decision Number 35/PUU-X/2012. Following the promulgation of Law Number 1 of 2023, Article 2 paragraph (1) formally deconstructs the rigidity of the colonial-inherited formal legality principle (Wetboek van Strafrecht) and transforms it toward a material legality principle. Consequently, living law is now recognized as a valid basis for criminal liability and acts as a complement to national law, manifested through additional criminal penalties in the form of fulfilling local customary obligations to support restorative justice. Nonetheless, the state imposes limitations through a codification mechanism into Regional Regulations guided by Government Regulations, which must be aligned with Pancasila, the 1945 Constitution, Human Rights, and general principles of law recognized by civilized nations to prevent legal uncertainty and subjective interpretations of the law.

TPS 3R is a community-based waste management approach aimed at reducing waste generation through reduce, reuse, and recycle activities. However, the operational sustainability of TPS 3R still faces several challenges,including  waste processing effectiveness, and community participation. This study aims to analyze the community’s Willingness to Pay (WTP) for waste management fees and to formulate priority recommendations for improving the performance of TPS 3R Banjar Sugihan using the Quality Function Deployment (QFD) method. The research was conducted in Banjar Sugihan Village, Tandes District, Surabaya City, involving 563 household respondents. WTP analysis was carried out using the bidding game method, while QFD analysis was conducted through the preparation of the House of Quality (HoQ). The results showed that the community’s WTP ranged from IDR 16,000 to IDR 19,000 per month. If applied to all 3,758 households in Banjar Sugihan Village, the potential retribution revenue is estimated to reach IDR 60,128,000–IDR 71,402,000 per month. The QFD analysis indicated that the priority strategies for improving TPS 3R performance include enhancing infrastructure facilities, optimizing waste sorting and processing, increasing waste processing capacity, strengthening human resource capacity, and implementing a WTP-based retribution system. Therefore, the implementation of a WTP-based retribution system and priority strategies derived from QFD analysis are expected to support the sustainability of waste management at TPS 3R Banjar Sugihan.

In the Education 4.0 era, schools face unprecedented challenges in managing teacher performance effectively. Traditional top-down performance management systems have proven inadequate for fostering continuous professional growth, intrinsic motivation, and adaptive teaching competencies required in increasingly technology-driven learning environments. This study aims to develop, validate, and assess the effectiveness of a School-Based Performance Management (SBPM) model designed to enhance teacher effectiveness across cognitive, affective, and pedagogical dimensions. Using a Research and Development (R&D) design following the ADDIE framework, the study was conducted in three phases: needs analysis, model development, and model validation. Participants included 12 school principals, 186 teachers, and 8 education experts from 24 public secondary schools in [Province, Country]. Validation by experts yielded a content validity index (CVI) of 0.91. Implementation resulted in statistically significant improvements in teacher effectiveness scores (t = 8.74, p < 0.001, Cohen's d = 1.23), digital pedagogy competency (mean increase = 22.4%), and student learning outcomes (mean improvement = 17.8%). The SBPM model provides a contextually responsive, evidence-based framework that empowers schools to manage teacher performance collaboratively, fostering professional accountability and sustainable instructional quality in Education 4.0.
