Judul: Applications Light Response Sinusoidal Curves For Carbon Dioxide Sink Measurements on Bamboo Betung (Dendrocallamus asper (Schult f.) Backer ex Heyne).
Abstrak: Planting plant such as bamboo Betung (Dendrocalamus asper (Schult f.) Backer ex Heyne) is one of the best way for reducing global warming effect. Bamboo Betung is giant grass which has been traditionally used by Indonesian people for construction material since a long time ago. It has better carbon sink ability than trees because of its C4 photosintesis mechanisms. In previous studies, the basic formula that was used for fitting plant’s light response curve was less precise. Quadratic and cubic equation make over estimate or under estimate result compared to those calculated based on annual increment. This study tried to obtain an ideal sinusoidal equation model to calculate the carbon sink capacity more precisely. To calculate carbon sink, it necessary to measure carbohydrate mass of leaves, number of leaves per cluster, and leaves area. Carbohydrate mass of the leaves is measured by carbohydrate analysis, where the mass of CO2 is known from the mass conversion of carbohydrates from photosynthesis. Light response sinusoidal curve approximated by multiple linear regression equation. Regression coefficient had been tested by t-student test to obtain the best model equation. In this study, probability value of each regression coefficient was selected P-value <0.1. This research proposed a sinusoidal equation as a basic equation for plant’s light response curve fitting. The sinusoidal equation was success for bamboo betung’s light response curve fitting (R2>60%). The best sinusoidal equations models for light response curve is Ŷ=A+BZ1(X–24(H–1))+DZ1Sin 2π(X−6) 24 . It had similar result in estimating carbon sink (82,35 kg/cluster/year) compared to those which calculated by annual increment (72,98-91,22 kg/cluster/year). It is better to choose sinusoidal equation than quadratic or cubic. In the future, light response sinusoidal curve equation can be used as a standard equation for many other green plants, therefore it can be used as consideration in choosing the most suitable plant to overcome the problem of increasing CO2.

Abstrak: Climate change are an effect from increase CO2 level in the air which can be reduced by planting green plant that have higher affinity toward CO2 such as bamboo. This research counted how much CO2 absorption using sinusoidal equation at three bamboo species. Sample taken from Bambusa vulgaris, Gigantochloa apus and Gigantochloa robusta leaves that were young, mature, and old respectively. The amount of CO2 absorption by bamboo were comparable to carbohydrate mass formed during the process of photosynthesis which calculated by determining the carbohydrate using Cu-Nelson method. This research showed that the mass value of carbohydrates from three bamboo species exceeds the CO2 absorption from slow growing species and almost close to fast growing species. The three bamboo species can be optioned in climate change reduction efforts caused an increase CO2 level in the air.
