      Abstract
      Research on detection and interpretation of the target on the ocean floor using side scan sonar instrument was conducted in waters of East Aceh, Lhokseumawe. The results showed that the value of the reflected signal from pipe and the unknown object are 1- 2.5 Voltage/Div, silty sand of 0.5 - 1 Voltage/Div, and mud is 0-0.5 Voltage/Div. Using FFT calculation the amplitude spectrum, the value of the pipe is higher than other objects, its about 1412 Volt/dB. The value of amplitude unknown object, mud and silty sand are 834.0728 Volt/dB, 106.2367 Volt/dB, and 238.9427 Volt/dB. The reflection coefficient of pipe respectively larger than the other detected targets.
       
      Dasar laut adalah sebagian dari bumi yang wilayahnya belum terjelajahi secara keseluruhan, baik luas, kedalaman, maupun potensinya. Salah satu cara untuk mendapatkan informasi tentang berbagai aspek dari dasar laut adalah dengan sistem akustik bawah air seperti side scan sonar. Side scan sonar mampu membedakan besar kecil partikel penyusun permukaan dasar laut, seperti batuan, lumpur, pasir, kerikil, atau tipe-tipe dasar perairan lainnya. Instrumen ini mampu menangkap gelombang pasir atau riak-riak kecil yang tingginya beberapa sentimeter serta mampu memberikan informasi dengan rinci tentang kondisi topografi dasar. Tujuan dari penelitian ini adalah mendeteksi dan menginterpretasikan target di dasar laut menggunakan instrumen side scan sonar.
