The integration of Artificial Intelligence (AI) into precision agriculture has significantly improved plant disease recognition; however, many existing deep learning models remain computationally expensive and feature-redundant, limiting their deployment on low-power and edge devices. To address these limitations, this study proposes a lightweight framework for maize leaf disease recognition based on serial deep feature extraction, dimensionality reduction, and machine-learning–based classification. A pre-trained MobileNetV2 network is employed as a fixed feature extractor to obtain discriminative visual representations, while Principal Component Analysis (PCA) is applied to reduce feature dimensionality by approximately 76%, retaining 95% of the original variance and improving computational efficiency. The compressed features are subsequently classified using a Radial Basis Function Support Vector Machine (RBF-SVM), optimized via grid search and cross-validation. Experiments conducted on a four-class maize leaf disease dataset (Northern Leaf Blight, Common Rust, Gray Leaf Spot, and Healthy), with class imbalance handled during training, demonstrate that the proposed MobileNetV2–PCA–SVM pipeline achieves 97.58% accuracy, 96.60% precision, 96.59% recall, and 96.59% F1-score, outperforming the DenseNet201 + Bayesian-optimized SVM baseline (94.60%, 94.40%, 94.40%, and 94.40%, respectively). This improvement corresponds to a 2.98% accuracy gain, a 55% reduction in error rate, an 86% reduction in model parameters (20.31M to 2.75M), and an 85% reduction in model size (81 MB to 12 MB). These results indicate that the proposed framework provides a compact and efficient solution with strong potential for deployment in resource-constrained agricultural environments.

Helminth infections caused by Soil Transmitted Helminths (STH) and Taenia sp. remain a major public health concern in tropical regions, including Indonesia, particularly among elementary school children. This study aimed to identify the presence of eggs and larvae of intestinal nematodes and cestodes in fecal samples collected from elementary school children in Bekoso Village, East Kalimantan. The research employed a descriptive survey method with a cross-sectional approach, and laboratory examinations were conducted using the Kato-Katz technique. A total of 16 fecal samples were examined to detect Ascaris lumbricoides, hookworm, and Taenia sp. eggs. The results showed that 12.5% of samples were positive for hookworm eggs, 12.5% for Taenia sp. eggs, and 6.25% for Ascaris lumbricoides eggs. These findings indicate that poor personal hygiene and inadequate environmental sanitation contribute to an increased risk of intestinal helminth transmission. The study highlights the importance of preventive efforts through the promotion of clean and healthy living behaviors, consistent use of footwear, handwashing with soap, and community participation in mass deworming programs to reduce the prevalence of intestinal helminth infections among elementary school children.

The results indicated an improvement in students' understanding of various PHBS indicators, including handwashing habits, waste management, healthy food consumption, physical activity, growth monitoring, avoiding tobacco smoke, maintaining toilet cleanliness, and eradicating mosquito larvae. The active participation shown by the students reflects a heightened awareness of practicing PHBS within the school environment. In conclusion, this educational initiative has delivered a positive impact on student knowledge and holds the potential to foster a sustainable culture of clean and healthy living, both at school and in their daily lives.

Hand washing is a major pillar in clean and healthy living behaviors (PHBS). However, there are still children who do not understand the correct handwashing technique so that germ cleaning is not optimal. This community service activity aims to improve students' knowledge and motor skills in practicing the six steps of hand washing according to World Health Organization (WHO) standards. The method used in this activity is interactive counseling combined with live demonstrations. The stages of the activity include providing material through audiovisual media (video/poster), direct demonstrations by instructors, and independent practice by all participants. In addition, a question and answer session was held to ensure student understanding and corrective feedback on inappropriate movements. Evaluation instruments in the form of observation sheets were used to assess the accuracy of the sequence, duration, and coverage of the hand area when washing. The result of this activity was the success of all participants in practicing the six-step sequence of handwashing correctly independently. The involvement of teachers and school health workers also strengthens the sustainability of this practice through regular monitoring. Through this education, it is hoped that early awareness will arise which has become a routine habit to reduce the risk of disease transmission in the school and home environment and support the creation of a culture of clean living from an early age.

As HIV transitions into a manageable chronic condition, optimizing lifestyle behaviors is key to achieving long-term health outcomes. This study aims to explore lifestyle behaviors in people with HIV (ODHIV) who participate in peer support groups as well as identify socioeconomic and clinical predictors of healthy lifestyle engagement. The research design was a cross-cutting analysis involving 250 ODHIV registered in a community support group. Lifestyle behavior was measured using  a modified Health-Promoting Lifestyle Profile II (HPLP-II) instrument. Multivariate logistic regression analysis was used to determine independent predictors, with Nagelkerke R² and Hosmer–Lemeshow tests  to assess model suitability. The results showed that 56.2% of respondents had a healthy lifestyle. Factors of higher education (OR = 2.77; p = 0.006), older age (OR = 2.32; p = 0.015), employment status (OR = 2.00; p = 0.029), and longer duration of ART therapy (OR = 1.17 per year; p = 0.003) were significant predictors. The model explains 32% of lifestyle variations, with ART compliance and substance control as the strongest behavioral domains. These findings confirm the role of peer support groups as a behavioural reinforcement environment, but socioeconomic disparities remain influential. The integration of theory-based lifestyle interventions into community-based HIV services is necessary to optimize chronic disease outcomes.

This study was conducted to understand how parenting styles significantly influence the process of shaping children’s behavior. The method used in this research was a qualitative approach, with data collection carried out through interviews and direct observation of participants aged 10–18 years who live in Cicendo District, Bandung. Based on the results conveyed by several participants, it can be seen that parenting styles play a very important role in children’s growth and development as well as in the formation of their emotional conditions. Parents who play a positive role such as giving more attention, communicating well, and providing full support tend to build positive responses and emotional stability in children. This helps shape a healthy personality and creates a comfortable home environment that makes children feel safe. In contrast, parents who display negative roles and parenting styles such as being harsh, lacking attention, and frequently engaging in conflict tend to make children feel pressured and lack self confidence due to unmet emotional support. As a result, children may limit their relationship with their parents, which leads to emotional instability. Overall, the discussion shows that the family is the primary foundation for children, as their growth and development are strongly influenced by how parents fulfill their roles in shaping children’s personalities, which ultimately impacts their lives in the future.

This study evaluates the legal perspective concerning business competition in Indonesia regarding alleged abuse of dominant power in the competition between digital platforms TikTok Shop (including the acquisition of Tokopedia) and Shopee. The method applied is normative juridical with a case study approach, referring to Law Number 5 of 1999, particularly Articles 19–21 related to market control and Article 20 concerning below-cost selling practices. The analysis focuses on inter-platform integration, aggressive discount strategies, use of cross-platform data, as well as post-acquisition behavior that may hinder healthy competition. The assessment is conducted by considering market structure, business actors' behavior, and law enforcement efforts by the Business Competition Supervisory Commission (KPPU). Research findings indicate that although TikTok Shop has strong competitiveness following the acquisition, proving the existence of abuse of a dominant position requires meeting legal and economic provisions rigorously. Therefore, the implementation of conditional approval and remedial measures by the KPPU is considered a reasonable step to maintain a healthy business competition environment in the digital era.
