【 摘 要 】

The high demand of seaweed had encouraged the farmers to expand their cultivation area, cause the spatial & temporal labor migration, water quality degradation, and destruction of the mangrove ecosystem. This research aims to provide information about seaweed cultivation in Nunukan for better management and planning for seaweed business sustainability. This research was conducted in April and May 2018 with 89 respondents. The result showed that the labor origin for seaweed farming mainly from South Sulawesi or from the illegal Indonesian Worker in Sabah - Malaysia. There are a big number of fishing boats capturing drifted seaweed in Ambalat and Karang Unaran water. This activity occurs due to the presence of "dead water" and "tide water" in Sebatik Strait. Seaweed farming cycle is about 35 days with an average number of ropes 500 - 600 per farm. There are 2,033 seaweed farms, which required 16,284 workers per year. The money circulation in seaweed business was estimated to be more than IDR 3.05-4.57 billion a month. This research recommends the local government to develop seaweed cultivation zoning to avoid conflict of sea area utilization and to improve marine water quality as well as to guarantee the sustainability of seaweed investment and business in Nunukan.
