Abstract: This study was conducted to determine the different turbidity and photoperiod effect toward bleaching condition of Sargassum sp. The study contained three studies (turbidity and photoperiod effect) using complete randomized design with 3 treatments and 6 replications in each study. Turbidity levels used were 10cm, 30cm and 50cm while photoperiod levels were 16 hours bright 8 hours dark, 12 hours bright dark and 8 hours bright 16 hours dark. The parameter observed were external and cytological anatomy observation. Each turbidity and photoperiod treatment significantly affected thallus color gradation and chlorophyll-α content of Sargassum sp. (p<0.05). The lowest thallus color gradation and chlorophyll-α content in different turbidity were found at 10 cm (38.167% and 0.02305 μmol), while highest were observed at 50 cm (45.095% and 0.03280 μmol). The lowest color gradation and chlorophyll-α content in different photoperiod were obtained from 8 hours bright 16 hours dark (41.446% and 0.02723 μmol) while highest levels were observed at 16 hours bright 8 hours dark (49.934% and 0.03385 μmol).
