Abstract

The rapid escalation of global metabolic health concerns emphasizes the critical urgency for advanced technological solutions that facilitate precise and automated monitoring of daily caloric intake. This research conducts a rigorous comparative analysis to evaluate the predictive performance and computational efficiency of Random Forest (RF) and Support Vector Machine (SVM) algorithms in classifying food calorie levels. The methodology commenced with a comprehensive data preprocessing phase involving multi-strategy missing value imputation and the discretization of caloric values into ordinal categories. Feature selection was meticulously executed using linear regression coefficients to identify high-impact nutritional variables. To ensure a robust evaluation, the dataset was partitioned using an 80:20 ratio for training and testing, complemented by cross-validation to minimize bias and variance. Experimental results indicated that the Random Forest (RF) demonstrated superior classification capabilities, achieving a peak accuracy of 94.8% alongside balanced precision and recall scores. Statistical evaluation via confusion matrices further revealed that Random Forest exhibited enhanced generalization across high-dimensional nutritional features compared to the geometric approach of Support Vector Machine (SVM). Furthermore, the analysis of computational overhead provided critical insights into the real-time deployment feasibility of each model. Ultimately, the findings suggest that the Random Forest serves as a robust engine for personalized dietary management systems, offering a reliable framework for future developments in preventive digital healthcare. By successfully bridging machine learning with nutritional science, this study establishes a benchmark for high-accuracy food classification essential for modern health-centric mobile applications.

Abstract

KUB ZIAE Sembalun Bumbung is a souvenir center located on the main tourist route of Sembalun, offering products such as black garlic, organic red rice, Rinjani coffee, and dried beans. However, this business faces challenges including weak brand identity, low visibility, and the absence of digital presence. Limited digital literacy among managers also results in reliance on conventional promotion methods. This community service program aimed to enhance KUB ZIAE’s competitiveness through two key strategies: (1) strengthening offline visual identity with signboards, banners, and product labels; and (2) developing digital assets such as Google Business Profile, Instagram, and Facebook accounts, along with content creation training. A participatory approach was applied, including needs assessment, co-design, intensive training, and on-site mentoring. The results showed improved business visibility with the installation of signboards and banners, while new product labels increased consumer trust. On the digital side, the Google Business account successfully appeared in search results, Instagram posts reached hundreds of accounts, and members gained skills in creating and managing promotional content. Although challenges remain, such as limited digital literacy and internet connectivity, the intervention effectively enhanced visibility, expanded market reach, and strengthened KUB ZIAE’s image as a leading souvenir center in the Rinjani tourism area
