Research Methodology

The study took place in Bungin Permai, located in the Tinanggea district of Southeast Sulawesi. This region is recognized for its favorable conditions for seaweed cultivation, particularly Sargassum plagiophyllum.

Experimental Design

The research employed a longline cultivation method, which is effective for maximizing space and optimizing growth.

Three different planting distances were tested:

• 10 cm
• 15 cm
• 20 cm

The duration of the experiment spanned 36 days, allowing sufficient time to assess growth performance under varying conditions.

Data Collection Process

Data collection focused on two main parameters:

1. Daily Growth Rate (DGR): This metric was crucial for evaluating how different planting distances influenced the growth of Sargassum plagiophyllum.
2. Water Quality Parameters: These included temperature, salinity, and nutrient levels, all essential factors affecting seaweed health and growth.
