Abstract
Analysis of 14C modern in coral aims to determine the activity of 14C modern of marine organism. Samples of living coral Porites lobata was taken from inner zone and middle inner zone, Spermonde Archipelago, Indonesia. This research used Liquid Scintillation Counting method. This method used three steps for sample preparation. The first step are physical and chemical washing. In this step, 9 % mass of sample has been removed from impurity. Second steps, CO2 Absorption. The sample entered in modificated absorption equipment and 14CO2 captured with KOH solution. The last steps, 8 mL sample solution mixed with 12 mL scintillator and measured used LSC Hidex 300SL at counting times 5-240 minutes. The activity of 14C modern in coral Porites lobata shown the differences activity between marine organism and land organism.
