Lisa Khumaeroh. 26050118120022. Hubungan Ketinggian Muka Air Laut Dan
Salinitas Pada Muara Sungai Ketiwon, Tegal. Elis Indrayanti, Baskoro
Rochaddi.
Intrusi air laut menjadi permasalahan daerah pesisir seperti Kota Tegal,
terutama di muara sungai seperti yang terjadi di Sungai Ketiwon. Penelitia n ini
bertujuan untuk mengetahui hubungan ketinggian air laut dan salinitas pada aliran
Sungai Ketiwon melalui daya hantar listriknya. Penelitian ini dilakukan tanggal 13-16 Juni 2022. Metode yang digunakan dalam melakukan analisis data adalah
menggunakan korelasi regresi linier untuk mengetahui korelasi ketinggian air laut
dan daya hantar listrik. Selain itu untuk mengetahui distribusi daya hantar listrik
vertikal menggunakan software Ocean Data View (ODV) 4.0. Berdasarkan
pengukuran di lapangan didapatkan nilai daya hantar listrik di sepanjang daerah
penelitian berkisar antara 516 µs/cm hingga 1999 µs/cm. Sedangkan besarnya nilai
daya hantar listrik yang dihitung berdasarkan korelasi ketinggian air laut dan
salinitas adalah 2494,33 µs/cm - 3631,176 µs/cm pada saat kondisi pasang dan
1428,332 µs/cm - 1672,517 µs/cm saat kondisi menuju surut. Hasil olahan
menggunakan korelasi regresi linier didapatkan nilai R sebesar sebear 0,7 – 0,9.
Angka tersebut mempunyai arti bahwa terdapat korelasi yang positif dan cukup kuat
antara ketinggian air laut terhadap daya hantar listrinya.
Kata Kunci : Salinitas, Daya Hantar Listrik, Intrusi Air permukaan, Pasang Surut,

ABSTRACT
Lisa Khumaeroh. 26050118120022. The Corellation of Sea Level and Electrical
Conductivity at the Ketiwon Estuary, Tegal. Elis Indrayanti, Baskoro Rochaddi.
Seawater intrusion is a problem in coastal areas such as Tegal City,
especially at the mouth of rivers such as what happens on the Ketiwon River. This
study aims to determine the relationship between sea level and salinity in the
Ketiwon River flow through its electrical conductivity. This study was conducted on
June 13-16, 2022. The method used in conducting data analysis is to use linear
regression correlation to determine the correlation of sea level and electrical
conductivity. In addition, to find out the distribution of vertical electrical
conductivity using Ocean Data View (ODV) 4.0 software. Based on measurements
in the field, the value of electrical conductivity along the study area ranged from
516 μs / cm to 1999 μs / cm. Based on measurements in the field, the magnitude of
the electrical conductivity value calculated based on the correlation of s eawater
level and salinity is 2494.33 μs / cm - 3631.176 μs / cm at high tide conditions and
1428.332 μs / cm - 1672.517 μs / cm when conditions are heading at low tide. The
processed results using linear regression correlation obtained an R value of 0.7 –
0.9. This number means that there is a positive and fairly strong correlation
between sea level and its conductivity.
