ANALISA KONSENTRASI DAN SEBARAN KLOROFIL-A DAN TSS TOTAL SUSPENDED SEDIMENT MENGGUNAKAN CITRA SATELIT LANDSAT-8 UNTUK MENGETAHUI KUALITAS PERAIRAN DI MUARA KALI PORONG STUDI KASUS PESISIR PANTAI SURABAYA-SIDOARJO

ABSTRAK

Klorofil-a dan TSS Total Suspended Sediment merupakan salah satu parameter yang cukup penting untuk mengetahui kualitas perairan di suatu wilayah. Klorofil-a dan TSS juga menjadi suatu parameter yang digunakan untuk mengukur tingkat pencemaran air dan sedimentasi yang diakibatkan oleh pembuangan material-material tertentu ke dalam air. Metode penginderaan jauh dengan citra satelit dapat menjadi solusi untuk melakukan penelitian masalah Klorofil-a dan TSS karena metode ini lebih efisien dan efektif dalam penelitian berskala spasial yang luas dan kontinyu. Salah satu citra satelit yang dapat digunakan adalah citra satelit Landsat-8 tahun 2014. Citra satelit Landsat-8 tahun 2013 mempunyai panjang gelombang yang dapat digunakan untuk meneliti Klorofil-a dan TSS multi temporal multi spektral memiliki 11 band dengan spesifikasi 16 bit karena semakin banyak bit semakin bagus kenampakan citra tersebut lebih sensitif terhadap perbedaan air laut pada kedalaman yang berbeda dan lebih mampu membedakan tampilan objek di permukaan sehingga mengurangi interpretasi. Proses validasi dilakukan dengan membandingkan nilai Klorofil-a dan TSS yang didapat dari pengolahan Citra Satelit dengan data Klorofil-a dan TSS hasil Ground Truth. Menurut Kepmen Lingkungan Hidup KLH No 12 Tahun 2003 dan PP. No 82 Tahun 2001 kandungan TSS yang normal adalah 50 mgL. Hasil yang diperoleh menunjukkan nilai TSS di daerah penelitian berkisar antara 0-150 mgL terdapat beberapa lokasi yang memiliki nilai TSS cukup tinggi yaitu 50 mgL mencapai 19. Menurut Bohlen dan Boynton 1966 kandungan ideal Klorofil-a dalam suatu perairan adalah1 5 mg L. Nilai Klorofil-a di daerah penelitian berkisar antara 0-18.7 mgL dengan rincian daerah yang memiliki nilai 0-15 mgL mencapai 99.78. Dengan demikian kondisi Klorofil-a masih sesuai standart kelayakan. Beberapa lokasi diindikasi telah terjadi degradasi kualitas perairan yang jika dibiarkan terus-menerus dapat merusak ekosistem di daerah tersebut. Penelitian ini dapat digunakan untuk memberikan informasi mengenai kondisi perairan di muara Kali Porong dan sekitarnya sehingga berguna bagi strategi pengelolaan wilayah pesisir ke depannya.


ABSTRACT

Chlorophyll-a and TSS Total Suspended Sediment is one of the parameters is quite important to know the water quality in a region. Chlorophyll-a and TSS also be a parameter used to measure the level of water pollution and sedimentation caused by the disposal of certain materials into the water. Method of remote sensing satellite imagery can be a solution to the problem of research Chlorophyll-a and TSS because this method is more efficient and effective in a broad spatial scale research and continuous. One of the satellite imagery that can be used are Landsat satellite imagery-8 in 2014. Landsat satellite imagery-8 in 2013 have wavelengths that can be used to examine the Chlorophyll-a and TSS multi-temporal multi-spectral has 11 bands with 16-bit specification as more and more bits the better the appearance of the image is more sensitive to differences in water sea at different depths and better able to distinguish objects on the display surface thus reducing interpretation. Process validation is done by comparing the value of Chlorophyll-a and TSS were obtained from the processing of satellite imagery data Chlorophyll-a and TSS results of Ground Truth. According to the Decree of the Environment MOE No. 12 of 2003 and PP. No. 82 2001 is the normal content of TSS 50 mg L. The results demonstrate the value of TSS in the study area ranged from 0-150 mg L there are several locations that have a high enough that TSS values 50 mg L of 19. According to Bohlen and Boynton 1966 the ideal content of chlorophyll-a in a body of water is 15 mg L. Chlorophyll-a values in the study area ranged from 0-18.7 mg L with details of the area that has a value of 0-15 mg L reached 99.78. Thus the condition of Chlorophyll-a is according to standard eligibility. Some locations have indicated that water quality degradation if allowed to continue may damage the ecosystem in the area tersebut.Penelitian can be used to provide information about the condition of the waters in the estuary and surrounding Porong so useful for coastal zone management strategies in the future.
