ABSTRACT
Chlorophyll-a is a phytoplankton pigment involved in photosynthesis. Chlorophyll-a concentration detection through satellite orbiting can only be infered the concentration of  chlorophyll-a at sea surface and could not estimate the sea primary productivity. Sea Primary productivity may last up to a depth of  compensation or the depth at which the intensity of  light stayed at least 1% of  sea surface light intensity. However, the aim of  this study is to find out the relationships between the concentration of  chlorophyll-a and primary productivity so that the concentration of  chlorophyll-a could be used to predict primary productivity. The linear regression equation have been applied to construct model explaing relationship between the chlorophyll-a concentration and sea primary productivity. The equation explaing on chlorophyll-a concentrations with primary productivity is PP = 22.746 + 95.536Keu (R²) = 0.66 where PP is the sea primary productivity, Keu is the average of  chlorophyll-a concentration throughout the water column. The results of  these equations can be applied to satellite imagery so that it can assist in monitoring water quality conditions.

ABSTRAK
Klorofil-a merupakan pigmen fitoplankton yang berperan dalam proses fotosintesis. Deteksi konsentrasi klorofil-a melalui satelit hanya dapat menduga konsentrasi klorofil-a permukaan dan bukan produktivitas primer. Produktivitas primer dapat berlangsung sampai kedalaman kompensasi atau kedalaman dimana intensitas cahaya tinggal 1% dari intensitas cahaya permukaan. Penelitian ini bertujuan untuk mencari hubungan antara konsentrasi klorofil-a dengan produktivitas primer sehingga konsentrasi klorofil-a dapat digunakan untuk menduga produktivitas primer. Analisis regresi linier dilakukan terhadap model hubungan antara konsentrasi klorofil-a dengan produktivitas primer. Persamaan hubugan antara konsentrasi klorofil dengan produktivitas primer adalah   PP = 22.746 + 95.536Keu  dengan (R²) = 0.66 dimana PP adalah produktivitas primer dan Keu adalah konsentrasi klorofil-a rata-rata di seluruh kolom perairan. Hasil persamaan tersebut dapat diaplikasikan untuk citra satelit sehingga dapat membantu dalam memonitoring kondisi  kualitas perairan.

Kata kunci: Konsentrasi klorofil-a, intensitas cahaya, produktivitas primer, citra satelit
