Background: Seaweed cultivation in Jeneponto Regency has been practiced for a long time and has become the main livelihood for most people in Mallasoro Bay. In cultivating seaweed, obstacles often arise in the form of failure experienced by seaweed farmers, or the quality of the harvest is not good. Methods: This study aims to develop a calendar for planting seaweed Eucheuma sp. in Mallasoro Bay, Jeneponto Regency based on sea surface temperature and chlorophyll-a distribution obtained from Landsat-8 imagery. Findings: Processing of Sea Surface Temperature Imagery and Chlorophyll-a processed using ENVI 4.8 dan 5.3 software, satellite images used in clean conditions and no cloud disturbances. In this research, data analysis was carried out descriptively. The water temperature that is good for seaweed growth is 27-30°C, for the Mallasoro Bay Sea Surface Temperature, which is suitable for planting seaweed in April, May, June, July, August, September, October, and November. While the classification based on the criteria of chlorophyll-a trophic status in marine waters, namely the range < 1 mg/L is classified as Oligotrophic, 1-3 mg/L is classified as Mesotrophic, 3-5 mg/L is classified as Eutrophic, and > 5 mg/L is classified as hypertrophic. Conclusion: from the results of image analysis for the distribution of chlorophyll-a in Mallasoro Bay, it shows that Mallasoro Bay throughout the year is at the Mesotrophic level or the fertility level of the waters is quite fertile because it is in the range of 1-3 mg/L. so b the seaweed planting calendar in Mallasoro Bay is obtained, namely in January, February, and December, equipment preparation such as cleaning and repair of seaweed planting equipment can be carried out, then at the end of March, May, July, and September, the procurement of seaweed seeds is carried out , in early of April, June, August, and October, Novelty/Originality of this article: it is possible to spread seaweed seeds, then in mid of May, July, September, and November, harvesting is carried out, so that seaweed cultivation in a year can be carried out 4 times cycle.

Conclusion

Based on the results of the research, the seaweed planting calendar in Mallasoro Bay was obtained, namely in January, February, and December, equipment preparations such as cleaning and repairing seaweed planting equipment could be carried out, then at the end of March, at the end of May, at the end of July, and at the end of September, seaweed seedlings were procured, in early April, early June, early August, and early October seaweed seedlings could be sown, then in mid-May, mid-July, mid-September, and mid-November harvesting is carried out, so that seaweed cultivation in one year can be carried out 4 cycles.

Future Research

Further research could investigate the impact of climate change on the suitability of the developed seaweed planting calendar, considering potential shifts in sea surface temperature and chlorophyll-a distribution patterns. Additionally, studies could explore the integration of other environmental factors, such as salinity and nutrient levels, into the planting calendar model to enhance its predictive accuracy and optimize seaweed growth. Finally, research is needed to assess the economic feasibility and social acceptance of implementing the satellite-based cultivation scheduling system among local seaweed farmers, including training programs and support mechanisms to facilitate its adoption and ensure sustainable seaweed farming practices in Mallasoro Bay. These investigations will contribute to a more resilient and productive seaweed aquaculture industry, benefiting both the environment and the livelihoods of coastal communities.
