Abstract
Pengamatan terhadap inland water level dapat dilakukan secara langsung melalui pengamatan terhadap rambu ukur. Namun metode ini memiliki kelemahan yaitu perlu pengamatan secara langsung di lapangan dan biaya perawatan yang mahal. Oleh karena itu penelitian ini mencoba menggunakan data satelit altimetri yang pada umumnya digunakan untuk menentukan tinggi muka air laut guna menentukan tinggi muka air di daratan. Satelit altimetri yang digunakan dalam penelitian ini adalah CryoSat-2 dan studi kasus bertempat di Danau Towuti dengan rentang waktu pengukuran dari tahun 2011 hingga 2018, Sulawesi Selatan. Satelit CryoSat-2 dipilih karena memiliki footprint yang cukup kecil sekitar 300 meter. Data satelit altimetri yang didapat kemudian dibandingkan dengan data pengukuran in-situ. Hasil penelitian menunjukkan bahwa penggunaan satelit altimetri CryoSat-2 SAR-Mode Level 2 guna menentukan inland water level dapat dilakukan. Namun dalam penggunaanya perlu dilakukan pemilihan data sehingga hasil penentuan water level dapat diterima.

Observation of inland water level can be done directly through the observation of the tide-gauge measurement. However, this method has a weakness that needs direct observation in the field and expensive maintenance costs. Therefore, this research tries to use satellite altimetry data which is commonly used to determine sea level surface. However, this study discusses the use of satellite altimetry data to determine inland water level. The satellite altimetry used in this study were CryoSat-2 and case studies were located at Lake Towuti, South Sulawesi with measurement ranges from 2011 to 2018. The satellite CryoSat-2 was chosen because it had a fairly small footprint of about 300 meters. Satellite altimetry data obtained later compared with in-situ measurement data. The results showed that the application of satellite altimetry CryoSat-2 SAR-Mode Level 2 to determine inland water levels was possible. But the use of data needs to be done so that the result of determination of water level is acceptable.
