Abstract
Laut Senunu adalah wilayah perairan laut yang masuk ke dalam kawasan Coral Triangle (Segitiga Terumbu Karang) yang terletak di Kepulauan Nusa Tenggara Barat. Kawasan Segitiga Terumbu Karang ini merupakan kawasan terkaya akan kehidupan laut di antara semua laut di Planet Bumi. Perairan laut Indonesia selalu berada dalam pengaruh berat baik dari aktifitas, perusahaan, minyak, transportasi laut serta aktifitas warga di daerah pesisir maupun daerah aliran sungai yang bermuara ke laut tersebut. Aktifitas tersebut membawa banyak penyebab resiko terjadinya kerusakan alam dan dapat berakibat merusak sumber daya laut.
Kualitas air di laut sangat bergantung dengan kualitas air dari sumbernya. Oleh karena itu diperlukan suatu parameter yang dapat digunakan sebagai standar penentuan kualitas air. Salah satu parameter yang dapat digunakan untuk penghitungan serta analisa kualitas air di Laut Senunu adalah Total Padatan Tersuspensi (Total Suspended Solid, TSS).
Data yang digunakan untuk mendapatkan persebaran TSS adalah data ground truth, hasil pengolahan citra Aqua MODIS. Data ground truth merupakan hasil pengambilan sampel berupa air laut yang selanjutnya dilakukan pengolahan di laboratorium. Proses pengolahan citra satelit menggunakan v
prinsip remote sensing, dimana citra menggunakan algoritma
Ocean Color 4 (OC4 – V4).
Hasil dari penelitian ini adalah peta persebaran TSS di
Laut Senunu, Nusa Tenggara Barat dan analisa beberapa data
diantaranya data citra terhadap ground truth, analisa data
lapangan, analisa konsentrasi klorofil-a secara temporal, dan
analisa parameter yang dapat mempengaruhi nilai dan sebaran
TSS. Berdasarkan hasil analisa dapat disimpulkan bahwa Aqua
MODIS memiliki korelasi yang cukup kuat terhadap data ground
truth dengan nilai koefisien korelasi R² = 81,3%. Secara
temporal, konsentrasi TSS di laut Senunu berada pada rentang
konsentrasi rendah yaitu sekitar 0,5 – 38 mg/l (tahun 2003 dan
2009), 0,06 – 0,1 (tahun 2013), sehingga dapat disimpulkan
bahwa kualitas air di laut Senunu tergolong bersih. Persebaran
konsentrasi TSS di laut Senunu pada setiap stasiun tidak merata
dan cenderung berubah-ubah. Hal ini dikarenakan faktor-faktor
yang mempengaruhi seperti arus perairan, angin, waktu
pengambilan data dan kondisi fisik perairan.

Senunu sea is the sea area which is into the Coral Triangle (Coral Triangle) that’s located in West Nusa Tenggara Islands. The Coral Triangle is the richest region between all marine life in the Earth. Indonesia's marine waters are always in a good heavy influence of activity, enterprise, oil, marine transportation as well as the activities of residents in the coastal areas and watersheds area that flows into the sea. These activities bring many causes of risk to damage the nature and the result will damage marine resources.
The quality of water in the ocean is very dependent on the quality of water from the source. Therefore, we need a parameter that can be used as a standard water quality determination. One of the parameters that can be used for the calculation and analysis of water quality in Senunu Sea is Total Suspended Solids (Total Suspended Solid, TSS).
The data that is used to obtain the distribution of TSS is a data ground truth, Aqua MODIS image processing results. Ground truth data is the result of taking a sample of sea water that further processing is done in the laboratory. Satellite image processing using remote sensing principle, where the image using an algorithm Ocean Color 4 (OC4 - V4).
The results of this study are the spread map of TSS in Senunu Sea, West Nusa Tenggara and the analysis of some data
vii
including image data to ground truth, the analysis of field data,
the analysis of the concentration of chlorophyll-a is temporarily,
and the analysis of the parameters that can affect the value and
distribution of TSS. Based on the analysis, it can be concluded
that the Aqua MODIS has a strong correlation of the data by
ground truth value of the correlation coefficient which R² =
81.3%. Temporarily, TSS concentration in Senunu Sea is at the
low of concentration range, it’s about 0.5 to 38 mg / l (2003 and
2009), from 0.06 to 0.1 (in 2013), so it can be concluded that the
quality of water in the Senunu Sea relatively clean. The
distribution of TSS concentration in Senunu sea at each station is
uneven and tends to fluctuate. This is because the factors that
influence such as water currents, wind, time data retrieval and
physical condition of the waters.
