ABSTRACT
Padina australis is a brown algae categorized as seaweed with a widespread in Indonesian coastal waters. We aimed to reduce the salt concentration of the brown seaweed P. australis by immersing it in flowing water. We used a completely randomized design (CRD) with different immersion durations (0, 4, 8, 12, 16, 20, and 24 h) of P. australis in flowing water. Each treatment received four replications. We evaluated dry matter (DM), organic matter (OM), crude protein (CP), ash, salt, and alginate contents. The results revealed a significant (p<0.05) impact on OM, CP, ash, salt, and alginate contents but did not significantly affect DM. Immersing P. australis in flowing water for 4 h is the optimal duration for decreasing salt content up to 97.62% while increasing CP and alginate levels proportionally. Immersion treatment in flowing water maintained the DM, OM, and ash contents.
