Abstract

Aims: This study aims to improve waste bank activities in Medan and make them more efficient Methodology and Results: The study involved the collection of secondary and primary data. The secondary data collected involved a general description of the study area, number, status, and location of the waste bank. Primary data included interviews and field research on selected waste banks. Importantly, survey and data collection were conducted from December 2017 to April 2018. A semi-structured interview survey approach was conducted to collect the data. Using the Material Flow Analysis (MFA) methodology, the findings of the study showed that of the total amount of the input material, 87.4 % is a recyclable waste and 12.6 % water. Also, the waste bank activities generate 87.2% recyclable items, 12.6% wastewater, and 0.2% residues. Conclusion, significance, and impact study: The findings are essential in understanding the use of resources to provide information for improving waste bank activities and waste management. Apart from the community, the government also plays a significant role in supporting the future of waste banks. This study found that waste bank activities are still conventional, with no technology adoption. In the future, the waste bank should be more efficient and manage large amounts of wastes, because the potential for recyclable products is still abundant.

Abstract

Food-wasting behavior can occur when someone does not finish the food they have taken. It can also be seen in purchasing or taking more food than they can consume. Food-impulsive behavior and personal norms are assumed to predict food-wasting behavior, and this study aims to prove this assumption. Personal norms reflect an individual's personal value system in specific situations that can influence specific behaviors, while food impulsive behavior refers to consumers' tendency to buy impulsively, without reflection, immediately, and impulsively. This research was conducted in Makassar City on 150 adolescents aged 12 to 19 years old, and the data were analyzed using multiple linear regression. This study provides three findings. First, food-impulsive behavior and personal norms together can predict food wasting by 32.5% (p=0.000; p<0.05). Second, food-impulsive behavior positively predicts food-wasting behavior by 11% (p=0.000; p<0.05), indicating that the higher someone's food-impulsive behavior, the higher their food-wasting behavior. Third, personal norms can negatively predict food-wasting behavior by 21.5% (p=0.000; p<0.05), indicating that the higher someone's personal norms, the lower their food-wasting behavior.
