Description Penelitian ini bertujuan untuk menganalisis nilai hambur balik permukaan dasar perairan berupa pasir dan lumpur. Echosounder bim tunggal Simrad EK15 frekuensi 200 kHz digunakan untuk perekaman hambur balik akustik permukaan dasar perairan. Pengambilan data dilakukan pada bulan tanggal  29 April – 2 Mei 2017 yang berlokasi di perairan Teluk Yos Sudarso, Kota Jayapura Provinsi Papua. Pengambilan contoh substrat digunakan untuk data validasi menggunakan sedimen grab. Hasil penelitian ini menggambarkan nilai rata-rata hambur balik permukaan substrat perairan pasir bervariasi antara -37.48 dB sampai -36.03 dB, dan lumpur bervariasi antara -46.98 dB sampai -45.15 dB. Hal ini juga menunjukkan bahwa substrat pasir memiliki tingkat kekerasan dan ukuran butir yang lebih besar dibandingkan jenis substrat lumpur substrat. Secara akustik, nilai hambur balik permukaan pasir akan lebih tinggi dibandingkan lumpur
The objectives of this research are to analyze the surface backscattering strength of seabed. The single beam echosounder Simrad EK15 with 200 kHz of frequencies was used for recordings of seabed acoustic backscattering. Data collection was conducted in April 29 – Mei 2 2017 which located in the Yos Sudarso Bay, Jayapura, Papua Province. Sampling substrate was taken for ground truth data using sediment grab. The results show that average value of surface backscattering strength of sand varied between -37.48 dB up -36.03 dB, and mud varied between -46.98 dB up -45.15 dB. It shows also that sand has a high substrate roughness, hardness, and grain size larger than the type of mud substrate. In acoustic backscattering values of sand were greater than mud.
