Abstract

Seaweed cultivation, particularly Eucheuma cottonii, plays an important role in the economy of coastal communities in Munte Village, Tana Lili District, North Luwu Regency. However, seaweed production has experienced a significant decline due to diseases such as bleaching and ice-ice, resulting in economic losses for farmers. This study aims to identify the economic losses caused by seaweed diseases using the Effect on Production (EOP) approach. Primary data were collected through questionnaires and direct observations, involving 88 respondents who are seaweed farmers in Munte Village. The analysis results show that the average harvest of healthy seaweed reached 1,597 kg/person in the last year, while the harvest affected by disease was only 241 kg/person in the last year. With an average selling price of seaweed at Rp 13,000/kg, the economic loss in the study location per person amounts to Rp 2,714,773/year, with the total economic loss for the entire population in Munte Village, particularly in Dusun Lengkong To Pao and Dusun Masollo, estimated to reach Rp 705,840,000 per year.
