The prevalence of non-communicable degenerative diseases in Indonesia continues to rise, particularly affecting adolescents and productive age populations due to unhealthy lifestyle patterns and free radical exposure. Purple sweet potato leaves (Ipomoea batatas L.), a locally abundant resource often regarded merely as agricultural by-product, contain significant bioactive compounds including polyphenols, flavonoids, anthocyanins, and terpenoids demonstrating potent antioxidant properties with IC50 values of 47.99 ppm. This study employs a qualitative descriptive literature review approach, analyzing 28 scientific publications spanning 2018-2025 sourced from Google Scholar and PubMed databases to examine the potential of purple sweet potato leaves as effervescent tablet raw material for degenerative disease prevention. Findings reveal that bioactive constituents effectively neutralize free radicals, prevent lipid peroxidation, and protect cellular structures from oxidative damage linked to diabetes, cancer, and cardiovascular disorders. The effervescent tablet formulation provides strategic advantages including enhanced solubility, accelerated absorption rates due to elimination of disintegration processes, pleasant carbonation sensation masking unpleasant active ingredient taste, and superior gastrointestinal tolerance. This innovation offers promising prospects for degenerative disease prevention through local food resource utilization, though experimental validation regarding optimal formulation, effective dosage determination, and clinical efficacy assessment remains necessary for practical implementation.

Various recent studies have shown that natural active compounds contained in traditional and fermented plants play a crucial role in supporting human health. These compounds include flavonoids, polyphenols, tannins, saponins, alkaloids, organic acids, probiotics, and other phenolic compounds. Detection of these compounds is usually carried out through specific chemical reactions that allow researchers to more precisely identify the bioactive components. Their biological activities are diverse, including antioxidant, antibacterial, anti-inflammatory, and antimicrobial properties, which work to protect the body from cell damage and infection. Natural compounds are considered promising agents for disease prevention and health promotion due to their broad biological activities. The fermentation process has been shown to increase the content of bioactive compounds while lowering the pH of the medium, creating conditions unfavorable for the growth of pathogenic bacteria. Furthermore, probiotics that develop during fermentation play a role in maintaining the balance of the gut microbiota, strengthening the immune system, and improving digestive health. Fermented products are widely recognized as functional foods because they contain beneficial probiotics and enhanced bioactive compounds. These naturally derived products, rich in secondary metabolites, have also been shown to have significant physiological effects, such as lowering cholesterol levels, controlling blood sugar, and maintaining stable blood pressure. This makes natural ingredients and fermented products not only sources of nutrition but also have great potential for development as functional foods and traditional herbal medicines. This highlights the importance of integrating traditional knowledge with modern scientific approaches in developing functional foods and herbal medicines. Therefore, research on natural bioactive compounds and the role of fermentation in enhancing their effectiveness is highly relevant to supporting sustainable public health.  

This study aims to utilize data mining techniques, specifically the K-Nearest Neighbors (KNN) algorithm, to classify leaf diseases in sugarcane (Saccharum officinarum). Early and accurate detection of leaf disease types is a crucial step in prevention and control strategies, thereby reducing potential crop losses caused by pathogen attacks. Leaf diseases in sugarcane, such as leaf scald, rust, and mosaic virus, are known to affect photosynthesis, inhibit growth, and reduce the quality and quantity of sugarcane produced. The classification process in this study was carried out through image analysis of infected sugarcane leaves, where features such as color, texture, and shape were extracted using digital image processing techniques. The KNN algorithm was chosen because of its non-parametric nature, ease of implementation, and its ability to provide accurate classification results even with limited data size. The working principle of KNN is to determine the class of a new sample based on the majority class of its k nearest neighbors in the feature space, making it very suitable for the case of leaf disease image classification. In addition to building a classification model, this study also examines disease prevention strategies based on the identification results. These strategies include the use of disease-resistant sugarcane varieties, the implementation of appropriate planting patterns, land moisture management, regular plantation sanitation, and the measured and environmentally friendly use of pesticides or fungicides. Model performance evaluation was conducted using accuracy, precision, recall, and F1-score metrics to assess model effectiveness across various data scenarios. The results of this study are expected to not only contribute to the development of decision support systems for farmers and related parties but also support the application of artificial intelligence-based technology in the agricultural sector.

Successful development encompasses various aspects of community life and cannot be separated from progress in the health sector. Health is one of the key indicators in determining the quality of life of a population. Therefore, attention to health—especially for vulnerable groups such as the elderly—is of great importance. Regular health check-ups serve as a preventive measure to help the community detect illnesses early and encourage individuals to take an active role in maintaining their own health. Several types of examinations are commonly provided free of charge during community service activities, including blood pressure checks, random blood glucose tests, uric acid level tests, and cholesterol level screenings. These health checks are especially beneficial for the elderly, as they help monitor overall health conditions and enable early management of diseases to prevent further complications. In this activity, a total of 40 elderly individuals voluntarily participated in the health screening. The methods used included health education sessions and direct examinations of blood pressure, uric acid levels, and random blood glucose levels. The counseling was delivered using simple and clear language, and it included a question-and-answer session to help participants better understand the information provided. The results of the examinations showed that some of the elderly participants had high blood pressure and elevated blood glucose levels, which led to recommendations for follow-up visits to nearby healthcare facilities. Through this health screening initiative, the overall health quality of the elderly participants improved, and their awareness of the importance of early detection increased. This activity is expected to motivate the broader community to pay more attention to their health and to undergo regular health check-ups. By taking a proactive role in managing their well-being, individuals can reduce the risk of serious complications in the future and contribute to the creation of a healthier society overall.
