Perairan kolam Ancol merupakan bagian dari perairan Teluk Jakarata. Kolam ini terbentuk karena adanya reklamasi pulau G, F di teluk Jakarta. Kolam perairan ini dijadikan tempat lalulintas perahu wisata dan olahraga Jetski. Survei batimetri merupakan kegiatan untuk mengetahui kedalaman suatu perairan. Metode pengukuran batimetri bisa dalaksanakan menggunakan prinsip akustik bawah air. Prinsip ini memanfaatkan cepat rambat gelombang suara di dalam air. Penggunaan perinsip ini telah berkembang pesat. Instrumen yang digunakan dalam melaksanakan survei batimetri pada saat ini dikategorikan menjadi singlebeam echosounder dan multibeam echosounder. Pada pelaksanaan survey kali ini menggunakan singlebeam echosounder teledyne echotrac CV 100. Pengambillan dan pengolahan data dari survey ini didasarkan standar IHO S-44 edisi ke-V. Penelitian ini bertujuan untuk melakukan uji analisis kualitas data dari survei batimetri di perairan kolam Ancol menggunakan singlebeam echosounder teledyne echotrac CV 100 dengan standar IHO SP 44 edisi ke-V. Hasil pengukuran menunjukan berdasarkan hasil antara lajur silang dan lajur utama di dapatkan hasil sounding masuk dalam orde 1a/1b, dan memiliki nilai kepercayaan lebih dari 95%.

Abstract

Indonesia adalah negara kepulauan terbesar di dunia yang berdasarkan data rujukan nasional memiliki luas 8,3 juta km2, terdiri dari 17.504 pulau, 1,9 juta km2 daratan, dan 6,4 juta km2 lautan. Salah satu informasi penting yang terkait dengan laut adalah data pasang surut air laut (Pasut). Badan Informasi Geospasial (BIG) sampai saat ini sudah membangun dan mengelola 216 stasiun pasang surut di seluruh Indonesia. Salah satu lokasi stasiun pasang surut adalah di Makassar di Dermaga Lantamal VI Makassar. Keberadaaan stasiun pasang surut air laut di Makassar sangat penting, terutama bagi kapal-kapal yang keluar dan masuk pelabuhan Makassar dan masyarakat sekitar, karena di wilayah tersebut termasuk area dengan kedalaman laut dangkal. Penelitian ini bertujuan mengetahui karakteristik pasang surut laut di Makassar yang diperoleh berdasarkan data tahun 2017-2021. Proses pengolahan data mengggunakan perangkat lunak T-tide yang menggunakan metode Least Square dalam perhitungannya. Hasil penelitian membuktikan bahwa rata-rata nilai HHWS, MSL, dan LLWS adalah 1.83, 1.19, 0.47 dalam satuan m (meter) yang ber-referensi ke palem pasut, sehingga ini adalah nilai muka laut yang lokal di Stasiun Makassar. Kemudian dari perhitungan bilangan Formzahl di stasiun pasang surut Makassar diperoleh nilai 1.07 – 3.06, dengan rata-rata bilangan formzahl 2.10, hal ini menjadi bukti bahwa tipe pasang surut Staisun Makassar adalah pasang surut campuran condong ke harian tunggal.
