Abstract

The study of the potential and strategies for collecting used cooking oil from households and micro-enterprises in Kuta Village, Kuta Subdistrict, Badung Regency, is crucial to support environmental conservation efforts and the development of a sustainable economy. This research aims to identify the potential availability of used cooking oil generated by households and micro-enterprises and optimize efficient and sustainable collection strategies in Kuta Village, Badung Regency. The research method used is descriptive with a quantitative approach and a cross-sectional study design. The research sample includes households and micro-enterprises using cooking oil. The study results show that the average cooking oil consumption for households is 1.05 liters per week, while for micro-enterprises, it is 25.82 liters per week. All respondents (100%) produce used cooking oil, with an average UCO generation of 82.86% of the total cooking oil consumption for households and 8.21% for micro-enterprises. The optimization strategies for UCO collection include direct collection by collectors, utilizing waste banks as collection points, and educating the community about the negative impacts of improper UCO disposal and its processing benefits. These findings provide a basis for efficient, sustainable, and environmentally friendly UCO management.

Abstract

This study aims to evaluate the effectiveness of using reusable water tumblers in reducing the consumption of bottled drinking water among senior high school students in Denpasar City. The research employed a mixed-methods approach, combining quantitative and qualitative methods through surveys using questionnaires and interviews with 322 respondents from two schools. The findings indicate that the average consumption of bottled drinking water before the habitual use of tumblers was 2.618 bottles per student per week, which decreased to 1 bottle per week after tumbler use became a regular practice. Pearson correlation analysis revealed a moderately strong negative relationship between tumbler usage frequency and plastic bottle consumption (r = -0.61). Furthermore, the linear regression model showed that each increase in tumbler usage level could reduce plastic bottle consumption by 0.69 bottles per week. The study concludes that the use of tumblers is effective in reducing bottled water consumption among students, although infrastructure support, such as water refill stations in schools, is still needed to optimize its impact.
