Abstract

Seagrass study needs to be continuously developed in order to know its potentiality of storing carbon. One of the studies uses carbondioxide (CO2) as growth rate indicator of the seagrass, Thalassia hemprichii, in a controlled laboratory scale. The seagrass used in this study was collected from Tongkaina waters, Sulawesi Utara. The study used Complete Randomized Design with treatments as follows: P1 – CO2 addition once per 3 days (5×100 ml/min for 25 minutes), P2 – CO2 addition once per 2 days (5×100 ml/min for 25 minutes), P3 – CO2 addition once a day (5×100 ml/min for 25 minutes), and control treatment (no carbondioxide). Results showed that daily growth rate was influenced by carbondioxide application and alkalinity. The highest wet weight occurred in P3 media in day-30, 36.67 gr, while the lowest wet weight was recorded in P1 in day-6, 27.60 gr. The highest growth rate was found in P3 in day-6, 1.310%, while the lowest was recorded in P1 in day-6, -1.772%. Carbondioxide application significantly affected the growth rate of the seagrass. Tukey test indicated that seagrass growth rate in P3 was significantly different from those of other treatments with P3>L: 0.747>0.65, while P1 and P2 did not have significant difference in growth rate with P1<L: 0.093<0.65 and P2<L: 0.068<0.65, respectively. Alkalinity measurement showed that the highest was recorded in P3, 80 mg/l and the lowest in P1, 40 mg/l.
