Abstract


Research on the growth of Thalassia hemprichii in Bone Batang Island, Spermonde archipelago has been done to find out the growth rate, the biomass and the production of T. hemprichii. The method of Plastochrone Interval has been applied for its leaf which is by making hole on by puncture its leaf midrib. The result showed that the average growth rate of T. hemprichii leaves in sand substrate area of Bone Batang island was 2.9 mm/day. The amount of biomass was 1527 g/m2. The production of T. hemprichii was 9.99 g/m2. The analysis showed that the sand substrate of this island contains organic material of 6.76%.

Keywords: growth rate, biomass, plastochrone interval, T. hemprichii
