NutriScan QR-Code in Improving Student Complaint Responsiveness Toward the Quality of the MBG Meal Program

Abstract

The Free Nutritious Meal (Makan Bergizi Gratis/MBG) program in Indonesia aims to improve the nutritional status of students through the provision of balanced meals. However, its implementation still faces various challenges, particularly related to inconsistent food quality and the lack of an effective complaint response system. This study proposes the NutriScan QR-Code as a digital innovation designed to improve student complaint responsiveness toward MBG meal quality. This research employed a quantitative approach using a pre-experimental design with a one-group pretest–posttest model. Data were collected using a Likert-scale questionnaire administered to high school students in grades 10–12 who were beneficiaries of the Free Nutritious Meals Program. A total of 59 respondents participated in the pretest phase and 46 respondents in the posttest phase following the implementation of NutriScan QR-Code. The data were analyzed using an Independent Sample t-test to examine differences before and after the implementation of the NutriScan system. The findings show that the implementation of the QR-Code-based NutriScan system significantly improved student complaint responses. This is evidenced by the t-test results (Sig. 2-tailed = 0.010 < 0.05), indicating a statistically significant difference between pretest and posttest scores. All measured indicators—including complaint frequency, ease of use, response speed, system clarity, and student satisfaction—showed improvement after the system was implemented. In conclusion, the NutriScan QR-Code system is effective in enhancing the efficiency, accessibility, and responsiveness of student complaint management regarding MBG meal quality. It also promotes transparency and encourages active student participation in monitoring school nutrition services
