Understanding Waste Bank Management: A Study of Coordination Between Waste Banks Unit Using Social Network Analysis

Waste banks are an innovation in waste management that is increasingly increasing in terms of quantity and type. This is because waste banks are a combination of elements of sustainable economic principles and community involvement. However, the effectiveness of waste bank management depends on a strong communication network among the network of parties involved in it. This study aims to determine the structure of the communication network between waste bank units (WBU) using social network analysis. The study was conducted on 43 waste bank units (WBU) in Makassar City. There were 4 findings in the study. First, the network structure showed a network that was still relatively low; only 2.2% of the total potential communication relationships were realized. This finding is relatively similar to the density of waste bank networks in developing countries. Second, WBU-AS emerged as a central actor in the WBU network. However, it appears that the distribution of centrality in the network is uneven, where WBU-AS emerged as a central actor while most WBUs were in peripheral positions with limited connections. Third, 2 other clusters were formed in the network with WBU-PB and WBU-LB each as supporting central actors. Fourth, it is necessary to further explore the factors causing many WBUs to be in isolated positions in the WBU network. Because there is a possibility that they will build their own communication channels with parties outside the network.
