摘要：Segara Anakan lagoon (SAL) is a dynamic estuary, downstream of several rivers in
Citanduy watershed, humid tropical climate and influenced monsoon, conditions that cause waters
to fluctuate. There are influence of natural and anthropogenic factors that impact on the increase
of aquatic organic matter, as phytoplankton indicator biota able to show its tolerance
characterized by fluctuation of chlorophyll content a. The purpose of this research is to know the
spatio-temporal distribution of chlorophyll- a SAL region. The chlorophyll- a measurement
method uses multitemporal landsat images and field measurements. The temporal approach (time
series) during 2016 refers to the monsoon wind pattern and spatially on seven different stations of
ecological characteristics. Data processing using ER Mapper 7.0 software and the preparation of
thematic data with Arc GIS software. Testing data accuracy using regression analysis. The results
of chlorophyll-a recording of landsat images ranged from 3,213 - 3,703 (mg / m3
) and field
measurements from 0.01 to 5.06 (mg / m3
). Temporally transitional seasons and on spatial
approaches, stations with anthropogenic characteristics have the highest chlorophyll content. The
condition is supported by the accumulation of aquatic organic materials, high rainfall and
upwelling phenomenon. Test of accuracy pertained high, shown with value of r = 0,94 at equation
y = -30.07x2 + 217.0x - 387.0, R² = 0.894 with regression characteristic is polynomial. The high
accuracy value in the equation, shows that the SAL area algorithm can be applied to obtain
chlorophyll content data in the field in the previous year with the support of satellite image data in
that year.
