Abstract
Sea grapes Caulerpa lentillifera or commonly also known by the local language lawi-lawi Bulaeng (Makassar), Latoh (Java), the language of trade green caviar is currently one of the mainstay of seaweed commodities by the Ministry of Maritime Affairs and Fisheries, because this type is in demand by export destination countries such as Japan, China, Philippines and Vietnam. This is because this sea grape is rich in minerals such as: I, P, Zn, Ca, Mg, Se, Fe, Mn, Co- vitamins such as: B vitamins, vitamin E, and some essential unsaturated fatty acids. In addition, it contains bioactive compounds including sesquiterpenoids, diterpenoids, ꞵ--sitosterol and caulerpenin which function as anti-cancer, anti-oxidative, anti-diabetic, help reduce cholesterol and prevent cardiovascular disease. With a broad market uptake, C. lentillifera sea grape has the potential to be used as an alternative commodity that can increase the income of fishermen who cultivate seaweed. The problem is, the seeds used only rely on seeds from the surrounding waters, so the production is seasonal and highly dependent on nature. This study aims to map the distribution of C. lentillifera sea grapes in South Sulawesi waters which have the potential as a source of seeds which will then be cultivated en masse by the community using technology and innovation. The research was carried out from August 2022 to October 2022. Sampling of Caulerpa sp was carried out at 3 stations where sea grapes grow in the waters of Takalar Regency using a square frame measuring 25x25 cm placed on a transect line along the coast. The results showed that the distribution pattern of C. lentillifera in the waters of Puntondo Takalar Village, South Sulawesi, was clustered with a Morisita index of 12 (value > 1) at GPS points Lat -5.592957o, Long 119.472463o to Lat -5.593118o, Long 119.472872o. Relative closure values were 69% for C. lentillifera and 31% for C. racemosa. The distribution frequency of C. lentillifera was found at station 2 observation stations while C. racemosa was only found at stations 1 and 3. Water quality included Salinity 30-34 ppt, temperature 28o-30o, pH 7.33-7.39, brightness 50-70% , the current speed is 0.0038-0.0051 cm/s.
