This study aimed to formulate a blue economy engineering model for seaweed cultivation (Kappaphycus alvarezii) by integrating water quality management, hydrodynamic regulation, planting distance optimization, and environmentally based business efficiency. A mixed-methods approach combined field true experimental design with quantitative descriptive analysis of marine economic performance. Variables included water quality, local current velocity, Daily Growth Rate (DGR), ice-ice disease prevalence, carrageenan yield and gel strength, and financial feasibility. Results showed that water conditions remained suitable for growth, with temperature of 27–30°C, salinity of 28–34 ppt, pH of 7.5–8.5, and dissolved oxygen above 5 mg/L. A planting distance of ±50 cm increased local current velocity by 54.2%, from 19.2 ± 2.3 to 29.6 ± 2.7 cm s⁻¹, while reducing dissolved organic matter from 3.8 ± 0.6 to 2.7 ± 0.5 mg/L. These conditions increased DGR by 19.7%, from 2.74 ± 0.18 to 3.28 ± 0.21% day⁻¹, and reduced ice-ice prevalence from 18.7% to 8.7%. Carrageenan yield increased by 10.5% to 35.8 ± 1.4%, while gel strength increased by 24.9% to 512 ± 27 g/cm². Financially, the R/C ratio increased from 1.28 to 1.51, while the Payback Period shortened from approximately 205 to 117 days. Thus, hydrodynamic-based planting distance optimization improved productivity, product quality, economic efficiency, and coastal cultivation sustainability. This strategy strengthens integration among microenvironmental management, disease risk reduction, carrageenan value addition, and investment efficiency within an adaptive blue economy framework, supporting sustainable coastal spatial utilization over the long term sustainably.
