Keyword : Citra Satelit Landsat-7 ETM+,Sedimen, Teluk Jakarta

Dalam tugas akhir ini telah dianalisis data citra satelit Landsat-7 ETM+ untuk menghitung laju luasan sebaran sedimen dan pola sedimentasinya di perairan Teluk Jakarta dengan menggunakan algoritma Ambarwulan dkk. Hasil perhitungannya dibandingkan dengan data lapangan di perairan pantai Muara Karang, Jakarta Utara dan Muara Tawar Bekasi Utara.


Galat relatif rata-rata Total Suspended Solid (TSS) dari citra satelit bulan Juni 2010 dan Agustus 2011 yang mewakili musim Timur dibandingkan dengan data pengukuran tanggal 14 Agustus 2010 di perairan pantai Muara Karang adalah 5,875%, sedangkan galat pada bulan Oktober 2011 yang mewakili musim Peralihan II dengan data lapangan tanggal 15 November 2010 di perairan pantai Muara Tawar sebesar 12%. Hasil analisis citra menunjukkan nilai TSS tinggi dengan kisaran 83 – 183 mg/liter terdapat di sekitar muara sungai, sementara perubahan luasan tutupan sedimen di perairan pantai sekitar Muara Karang berkurang masing – masing sebesar 20,1, 21,3, dan 32 km2 pada periode 22 April - 8 Mei, 12 – 28 Agustus dan 28 Agustus – 13 September 2011 serta bertambah 26,1 km2 dalam rentang waktu 8 Mei - 9 Juni 2010 dan 35,6 km2 antara tanggal 6 – 22 April 2011. Perubahan nilai TSS di kedua lokasi tersebut bertambah sebesar 0,04, 0,0272 dan 0,006 kg/m3 antara tanggal 6 dan 22 April 2011, 21 Mei dan 22 Juni 2010 serta 12 dan 28 Agustus 2011, sedangkan dalam rentang waktu 22 April – 8 Mei 2011 dan 28 Agustus – 13 September 2011 terjadi pengurangan TSS sebesar 0,02 dan 0,271 kg/m3.


Pada musim Barat terjadi penumpukan sedimen di bagian timur Teluk Jakarta dan pantai barat Muara Karang, sedangkan di musim Timur penumpukan sedimen terdapat di bagian barat teluk. Pada Peralihan I dan II sedimen menyebar secara merata sepanjang perairan pantai.

Deskripsi Alternatif :

In this thesis has been analyzed imagery satellite data from Landsat-7 ETM+ to calculate the alteration rate of sedimentation area and its pattern in the Jakarta Bay with the Ambarwulan et. al algorithm. The calculation results have been compared with field data in the coastal waters of Muara Karang, North Jakarta and Muara Tawar, North Bekasi.


The mean relative error of Total Suspended Solid (TSS) from June 2010 and August 2011 that represents East Monsoon compared to observed data on 14th August 2010 in the coastal waters of Muara Karang is 5,875%, while the error on October 2011 that represents Transition Monsoon II compared to measured data on 15th November 2010 in the Muara Tawar coastal waters is 12%. Analysis results shown high TSS between 83 – 183 mg/liter at the surrounding of the estuaries of some rivers flowing to the Jakarta Bay, while the alteration of sediment coverage area at Muara Karang coastal waters were decreased by 20,1, 21,3, and 32 km2 in the periode of April 22 - May 8 , August 12 – 28, August 28 – September 13, 2011 and increased by 26,1 km2 in range time May 8 - June 9, 2010 and 35,6 km2 between April 6 – 22, 2011. Sediment concentration changes at both location were increased by 0,04, 0,0272 and 0,006 kg/m3 in April 6 – 22, 2011, May 21 and June 22, 2010 and August 12 - 28, 2011, while in time period April 22 – May 8, 2011 and August 28 – September 13, 2011 the concentratios were decreased by 0,02 and 0,271 kg/m3.


In the west monsoon sediment accumulations were occurred at the eastern side of Jakarta Bay and at the western coast of Muara Karang, while in the east monsoon sediment are accumulated in the western side of the bay. In transition monsoon I and II sediments were spread along the Jakarta Bay coastal waters.
