SPATIAL DISTRIBUTION OF CHLOROPHYLL-a INCIRATA LAKE USING REMOTE SENSING
Abstract: The research of
spatial distribution chlorophyll-a in Cirata lake using remote sensing. The
method used is secondary data collection, remote sensing, and statistical
analysis. Remote sensing method comprising, Pansharpening, radiometric
correction, interpretation and image extraction, and datapresentation.
Statistical analysis performed correlation and linear regression to get the
mappingformula chlorophyll-a. Purpose of this study is to apply remote sensing
method as a tool monitoring of the Cirata lake. The research objective is to
obtain a model of remote sensing data with the dataof chlorophyll-a.The results
showed linear regression equation in the frst quarter, Y= 13.982*(x)- 50.673
with r = -0.33, R2 = -0.007, and P-value = 0.39. Second quater, Y=
4.366*(x)+2.442, r = 0.33, R2 = -0.031, and P-value = 0.40. Third quater, Y=
7.394*(x)+9.393, r = 0.11, R2 = 0.29, and P-value = 0.79. Fourth quater, Y =
2.917*(x) + 8.324, r = 0.74, R2 = 0.70, and P-value = 0.022.Spatial
distribution of chlorophyll-a in Cirata lake concentrated on central of the
lake area markeddarker colors or chlorophyll-a concentration ≥ 10 mg/m3 with a
clumped pattern. Intake area has clumped pattern dominated the light colors or
chlorophyll-a concentration ≥ 10 mg/m3 and inlet area has clumped pattern with
a light color or chlorophyll-a concentration ≥ 8 mg/m3.
