This research is a quantitative study with a pre-experimental design using a one-group pre-test and post-test approach to assess the impact of training on health literacy and knowledge of the food traffic light system among food handlers at the canteen of Politeknik Kesehatan Megarezky. Pre-experimental research aims to test the effect of an intervention on characteristics of interest to the researcher. This study was conducted from September to December 2024 using validated questionnaires.The respondents in this study were 13 individuals working as food handlers. The data were analyzed descriptively using Microsoft Excel and SPSS 21. The paired t-test results for the literacy variable showed a Sig value of 0.000 (≤0.05), indicating an improvement in health literacy regarding the Food Traffic Light System before and after the training. Regarding knowledge, the paired t-test results also showed a Sig value of 0.000 (≤0.05), indicating a significant difference in knowledge before and after the training. This study emphasizes the importance of improving literacy and knowledge for food handlers to create a healthy canteen. Additionally, the study recommends conducting research with a larger sample and using complex method for future studies.Keyword: Food Traffic Light System, Healthy Canteen, Health Literacy, Health Promoting University

Abstract

This study explores the functions and meanings of belis, a traditional dowry or bride price in Manggarai culture, within marriage ceremonies in Mbuit Village, West Manggarai. Employing a descriptive qualitative approach grounded in symbolic interactionism, data were collected through in-depth interviews with cultural informants, supported by observation and literature review, and analyzed using the Miles and Huberman three-step framework. The findings reveal that belis serves as a key cultural element, fostering social integration, promoting harmony, and preserving traditions in Manggarai marriages. Symbolically, belis represents the union of two families (social integration) and signifies an economic exchange. The study also highlights the challenges faced by families, particularly those from lower socio-economic backgrounds, in fulfilling the belis requirements, underscoring its deep cultural significance and the commitment it represents.
