Penta Helix Model Communication to Promote Appropriate and Green Technologies for Ayung River Preservation Program in Bali

The Ayung River Preservation Program in Bali involves the community and stakeholders to address the degradation of the river. This research focuses on implementing the Penthealix communication model to promote green technology and involve stakeholders in preserving the Ayung River, which is the longest river on the island. The degradation of the river watershed highlights the critical state of the water supply in Bali. Existing data shows that the decrease in river flow rates along the watersheds in Bali has reached 60%, which has the potential to cause a water crisis on the island of Bali. Using the case study method, this research uses in-depth interviews and FGDs with local communities and other stakeholders. Secondary data was also collected from reports in newspapers. The results of the study show that efforts to preserve the Ayung River are implemented in the Green Technologies Program, which includes: 1) Biopori Holes and Infiltration weels; and 2) Community-based waste management. In its implementation, a Penta-Helix collaboration model was built between 1) The Government; 2) Communities; 3) businesses; 4) Academicians; and 5) the media. This program runs the Penta-Helix partnership model, which prioritizes Attribute, communication, and Conflict Resolution Technique efforts to achieve Partnership Commitment between stakeholders.
