Evaluating the Effectiveness of Quasi-Experimental Designs in Promoting Sustainable Waste Separation Behavior Through Waste Management Websites
Main Article Content
Abstract
This research investigates of the effectiveness of a quasi-experimental research design in promoting sustainable behaviors through a waste management website, with a focus on the Generation Z’s perception. The research objectives are to study the influence of a recycling waste management website on participants' perceptions in various aspects, to examine the effects of website useage experience on participants' perceptions, and to explore the relationship between the perceived effectiveness of online resources provided on the website and participants' recycling behaviors. The sample consisted of 49 participants in the waste management website activity, selected through convenient sampling from high school students participating in a technology transfer to the community project. The research instrument was a pre and post website usage questionaire. The data were analyzed using the Wilcoxon signed-rank test to compare outcomes before and after intervention. The results revealed that participants' perceptions, usage experience, and recycling behaviors increased significantly at the 0.001 level after using the website. The research hypothesis was confirmed that digital platforms such as websites can promote awareness and sustainable behaviors. This study contributes to the understanding of how digital interventions can promote environmental sustainability, particularly among tech-savvy younger generations. These insights are beneficial for policymakers and environmental organizations in developing digital platforms to promote sustainable waste management.
