Abstract
This research aimed to determine the effect of various macroalgae extract in Lombok marine water to mortality of Artemia salina larva. About 9 species of macroalgaes including Gracilaria sp, Sargassum crassifolium, S.policistum sp1, S.policistum sp2, S.cristaefolium, Achantophora muscoides, A.spesifera, Padina sp, and Gelidium ratifolium, were extracted through maseration method using methanol and dichloromethane. Each extract with 3 level of concentration (5ppm, 10ppm, 100 ppm for DCM phase and 100ppm, 200ppm, 300ppm for methanol phase) was added to Artemia salina cultures (2 days in age) containing 10 individuals respectively. The results suggest that addition of Sargassum crassifolium, S.policistum sp1, Achantophora muscoides, A.spesifera and Gelidium ratifolium extract brings the high number of mortality to Artemia salina larva ( >60% in average). The average number of larva mortality that was caused by addition of S.policistum sp1, Achantophora muscoides, and Gelidium ratifolium methanol extract are 7, 10, 10 respectively. Additon of Sargassum crassifolium, S.policistum sp1, Achantophora spesifera and Gelidium ratifolium DCM extracts give the average number of mortality about 6, 6.33, 7.33, and 10 respectively. Furthermore, the median lethal concentration (LC50) ef each extracts should be measured and performed in other research.
