The Adoption of Plasma Fine Bubble Innovation in a Seaweed Processing Factory to Implement Blue Economy Concept (A Case Study of PT. Hakiki Donarta)

Introduction: Seaweed is one of Indonesia's leading commodities in the mariculture sector, and its production produces wastewater. PT Hakiki Donarta is a leading seaweed processing company that currently handles its IPAL still using Polyaluminium chloride chemicals and aeration ponds with the help of water wheels. Objectives: This condition receives special attention in the waste handling process so that the business can be environmentally friendly and sustainable as the blue economy concept is applied. Thus, Plasma Fine Bubble (PFB) will be tested to compare chemical handling and PFB handling to manage wastewater and support the blue economy concept. Methods: Two of the principles of the blue economy are innovation and adaptation. IPB has innovative Plasma Fine Bubble (PFB) technology and has the expertise to develop commercialization strategies for PFB to support the implementation of the Blue Economy. To be in line with the roadmap, there are five main steps (key phases) and milestones in program development (innovation solutions), as follows: Prepare the Plasma Fine Bubble (PFB) System to be implemented; PFB System manufacturing and assembly process; Implementation and performance testing of the PFB generator at the Factory; Adopt and Scale the PFB System using Benefit-Cost Analysis; Create a business plan using PFB technology. Results: The 5 key phases are completed step-by-step. Key phases 1 and 2 were completed from July to September 2023. The results of completing key phases 1 and 2 are explained. Key Phase 1: Preparing the Fine Bubble (PFB) plasma system to be implemented. Functional requirements of the PFB system implementation. Condition of the wastewater of the factory. The current situation surrounding the factory. Key Phase 2: PFB System Manufacturing and Assembly Process Conclusions: The study confirms that Plasma Fine Bubble (PFB) technology is highly effective and sustainable for managing seaweed processing waste. By reducing waste management costs by 2%, reducing chemical costs by 40%, and addressing environmental concerns, PFB represents a significant step forward in advancing the blue economy.
