Abstract
Negara kepulauan merupakan negara yang seluruhnya terdiri dari satu atau lebih kepulauan dan dapat mencakup pulau-pulau lain. Seperti halnya Negara Indonesia dimana dua per tiga luas Indonesia didominasi oleh lautan atau perairan. Lautan menjadi salah satu sumber kehidupan bagi masyarakat Indonesia, termasuk bagi para nelayan. Nelayan mencari rezeki dan peruntungan melalui hasil tangkapan ikan yang didapatkan setiap harinya. Ekosistem ikan tidak terlepas dari produsen makanan yang terdapat di laut, yakni klorofil-a pada fitoplankton.
Data yang digunakan untuk mendapatkan persebaran klorofil-a adalah data ground truth, hasil pengolahan citra Aqua MODIS, dan Landsat 8. Data ground truth merupakan hasil pengambilan sampel berupa air laut yang selanjutnya dilakukan uji laboratorium. Proses pengolahan citra satelit menggunakan prinsip remote sensing, dimana masing-masing citra menggunakan algoritma yang berbeda, yaitu ATBD 19 dan algoritma klorofil-a pada Landsat 8.
Hasil dalam penelitian ini adalah peta persebaran klorofil-a di Pantai Surabaya-Sidoarjo dan analisa beberapa data diantaranya data citra terhadap ground truth, analisa antar citra, dan analisa konsentrasi klorofil-a secara temporal. Berdasarkan pada proses analisa dapat disimpulkan bahwa Aqua MODIS memiliki korelasi yang kuat terhadap data ground truth dengan nilai koefisien korelasi sebesar 78,88%. Sedangkan hasil
pengolahan citra Landsat 8 mempunyai korelasi yang sangat
lemah sebesar 16,24%. Secara temporal, konsentrasi klorofil-a di
daerah Pantai Surabaya – Sidoarjo berada pada rentang
konsentrasi sedang yaitu sekitar 1,001 – 2 mg/m³. Hal ini
dikarenakan beberapa faktor seperti kondisi fisik perairan,
musim, dan arus perairan.
======================================================================================================
Archipelago country is the country that all of its region contains one or more islands and can cover another islands. As Indonesia that two third of its wide is domineered by sea or water. Sea is becoming one of living source to Indonesian, especially for fishermen. Fishermen search their livelihood from totally fish catched every day. Ecosystem of fish is coming from food producer in the sea, that is chlorophyll-a in phytoplankton.
Data that is used to know the chlorophyll-a distribution is ground truth data, results of Aqua MODIS processing and Landsat 8. Ground truth data is the result of sea water sample which are tested in laboratory. Satellite image processing uses remote sensing principle where each satellite use different algorithm, such as ATBD 19 and chlorophyll-a algorithm in Landsat 8.
Result in this research is chlorophyll-a distribution map in Surabaya – Sidoarjo coast and analysis some data that is between image and ground truth, inter image analysis, and temporal analysis of chlorophyll-a distribution. Based on analysis processing can be concluded that Aqua MODIS has a high correlation with ground truth data in 78,88% coefficient correlation. Whereas Landsat 8 processing result has a weak correlation about 16,24%. Temporarily, chlorophyll-a concentration of Surabaya – Sidoarjo Coast is in medium concentration about 1,001 – 2 mg/m³. It is caused by some factor
such as physical condition of water, season, and currents.
