Coral reef restoration efforts need to be planned to improve the condition of damaged coral reef ecosystems. Microfragmentation is one of the methods used for massive coral reef restoration. This research aims to determine the growth rate and survival rate of Porites and Cyphastrea using different fragment sizes. The coral fragments were used 1 cm 2 , 2 cm 2 , and 4 cm 2 . This research was conducted in a maintenance tank owned by PT Pura Baruna Bahari located on Sambangan Island from September to December 2021. Observation of growth rate and survival rate were checked every one week by taking photos of coral fragments. These photos were processed using Image J. The results show that the highest growth rate of Porites was found in fragments 2 cm 2 (0.272 cm 2 /week) and the lowest was obtained from fragments 4 cm 2 (0.092 cm 2 /week). The highest growth rate of Cyphastrea was found in fragments 2 cm 2 with the growth rate of 0.736 cm 2 /week and the lowest was obtained from fragments 4 cm 2 with the growth rate of 0.447 cm 2 /week. The survival rates of coral fragments Porites and Cyphastrea were 100% and 98.21%, respectively. The results of growth rate analysis using One Way ANOVA showed that there was a significant difference (P<0.05) on Porites growth rate and no significant difference (P>0.05) were found on Cyphastrea’s growth rate. The highest growth rate was achieved at 2 cm 2 fragments of Porites and Cyphastrea fragments.
