"Isi Piringku" is a dietary guideline developed by the Ministry of Health of the Republic of Indonesia as part of a balanced nutrition campaign. Understanding this concept is particularly important for elementary school-aged children, as this is a critical period for physical growth, mental development, and the formation of healthy lifestyle habits. A balanced nutritional intake plays a vital role in improving learning concentration, supporting physical activity, and preventing various diseases caused by nutritional deficiencies or excesses. However, the dietary behavior of elementary school students remains far from balanced nutrition principles, with an average achievement of only 53.9%. Based on this condition, this Community Service Program (PkM) aimed to improve the knowledge, skills, and behavior of Youth Red Cross (PMR) members at SDN Krapyak in consuming food according to balanced nutrition guidelines using the “Isi Piringku” media. The activities carried out included obtaining permission, conducting socialization, training on the use of the “Isi Piringku” media, and providing ongoing mentoring. Through this program, it was expected that PMR members could become change agents and role models for their peers in implementing healthy and balanced eating habits. The results of the activity showed that the mentoring was successfully conducted. There was a significant improvement in the knowledge and skills of PMR members, as reflected in the increase in the average score from 70.8 to 90.97 after the intervention. This indicates that the approach using the "Isi Piringku" media is effective in promoting balanced nutritional behavior among elementary school children.

This research presents a personalized, context-aware recommender system to suggest Places of Interest (POIs) using a hybrid approach combining Bayesian inference and collaborative filtering. The system explicitly addresses the cold-start problem that new users face and improves recommendation accuracy by considering contextual variables such as user mood, budget, companion, and location. The system collects real-time contextual inputs for new users with no historical data and applies Bayesian inference to generate relevant POI suggestions. As users begin to interact and provide ratings, the system progressively shifts to a collaborative filtering mechanism, leveraging cosine similarity to identify similar users within comparable contexts. The recommender system focuses on three categories of POIs: restaurants, hotels, and landmarks. These locations are retrieved through the Google Maps API, and only mapped locations are considered. The system was implemented on Android devices and evaluated through a user study involving 25 participants from diverse backgrounds, including software developers, IT students, and general users. Evaluation metrics such as normalized Discounted Cumulative Gain (nDCG) and classification accuracy were used to assess recommendation quality. Results demonstrate that the system performs better than traditional methods, with nDCG improvements reaching up to 83 percent. Users reported high satisfaction regarding the recommendations' accuracy, ease of use, and contextual relevance. While the system offers significant improvements, it also has certain limitations. Its dependency on Google Maps data may restrict its scope, and using only four contextual factors limits the system’s adaptability to more complex user preferences. Future enhancements could include additional dynamic contexts such as weather, POI popularity, and time-related trends, as well as integrating more advanced models to increase personalization and flexibility in real-world applications.
