    Abstract

    ABSTRACT Study of Chlorophyll Characteristic on the Leaves As Photodetector Organic Material By Ar Rohmah M0202017 The aim of research was studied the optically and the electrically chlorophyll on the leaves such as spinach of Amaranthus sp, morinda citrifolia and cassava leaves. Measurement of the optic is absorbance with Uv-Vis Spechtrophotometer and the electric is conductivity with two point probe methods. Absorbance of spinach are higher than the others. I-V data showed the conductivity on the dark of spinach, morinda citrifolia and cassava leaves are (3,8133 ± 0,0007) x 10-3 (Ωm) -1 , (3,2761 ± 0,0006) x 10-3 (Ωm) -1 dan (1,893 ± 0,001) x 10-3 (Ωm) -1 , while the conductivity on the lighted of spinach, morinda citrifolia and cassava leaves are (4,1947 ± 0,0007) x 10-3 (Ωm) -1 , (3,4061 ± 0,0007) x 10-3 (Ωm) -1 and (2,0973 ± 0.0006)x10-3 (Ωm) -1 . The increasing of conductivity on the lighted spinach are higher than the others, are ( 0,38 ± 0,06) x 10-3 (Ωm) -1 . The total chlorophyll of spinach are 27 mg/l, morinda citrifolia are 22 mg/l and cassava leaves are 16 mg/l. The reducing of total chlorophyll happened by degradation of chlorophyll molecules become its generation molecules.
