Abstract

Background: Household food waste presents a significant barrier to sustainable food security, with notable environmental, economic, and nutritional implications. This study evaluated the effectiveness of visual meal-planning education in enhancing knowledge of menu planning, influencing food purchasing behavior, and reducing household food waste in Tanah Sareal District, Bogor City. Methods: A pre-experimental, one-group pretest–posttest design was employed with 50 housewives responsible for household food management, selected through total sampling. The intervention included an initial educational session and refresher sessions every four weeks over a 12-week period, utilizing visual meal-planning materials. Data collection involved structured questionnaires to assess knowledge and behavior, as well as direct measurement of food waste using a weighing method over eight consecutive days. Data were analyzed using descriptive statistics and the Wilcoxon Signed Rank Test. Results: Findings indicated a significant increase in knowledge scores at the third evaluation (p = 0.001), reflecting improved understanding of menu planning and food purchasing. While planning and purchasing behaviors improved, the changes were not statistically significant. However, householdfood waste decreased significantly by 41 g/capita/day (60%) following the intervention (p = 0.000). Conclusion: In summary, visual meal-planning education effectively enhances knowledge and substantially reduces household food waste, although its influence on behavior change is limited.

Abstract

Background: Food waste remains a significant challenge in Indonesia, particularly within urban areas. This study evaluated the impact of educational interventions regarding food expiration dates on mothers’ knowledge and food waste behavior in urban households in the Tanah Sareal District, Bogor City Methods: A quasi-experimental, one-group pre-test and post-test design was implemented with 55 housewives. The intervention used posters and balanced nutrition modules that emphasized food storage and expiration date labeling. Data were collected through a validated questionnaire and analyzed using descriptive statistics, paired t-tests, and chi-square tests. Result: Results indicated a significant increase in mothers’ knowledge, from 26.87 ± 3.91 before the intervention to 29.16 ± 1.31 after the intervention (p=0.0001). Food waste behavior also improved, as the average amount of food waste decreased from 73.44 ± 48.06 grams to 31.99 ± 27.30 grams (p=0.0001). Additionally, a significant association between knowledge and food waste behavior was observed following the intervention (p=0.022). Conclusion: These findings indicate that education about food expiration dates can enhance knowledge and reduce food-waste behavior among urban households. Community-based educational interventions employing simple visual media may offer an effective strategy for reducing food waste and promoting sustainable household food management.
