Abstract
This paper briefly describes the design and analysis of the structure of ocean bottom units (OBU) as a pair of surface buoys to detect tsunami early. This engineering work such as any other marine construction is based on naval architecture. The design concept OBU is firstly made then the stability calculation is conducted, finally the structural strength is calculated for load case of hydrostatic and impact as the OBU landed on approximately 2000m of ocean depths.

Gambar 5 memperlihatkan prototipe dari Ocean Bottom Unit (OBU) hasil desain tim perekayasa INA-TEWS-BPPT, sedangkan pada Gambar 6 diperlihatkan OBU tersebut sedang saat posisi mengapung dipermukaan laut setelah 2 bulan berada di dasar laut untuk keperluan perawatan rutin
Summary
Bidang penelitian yang diminati adalah dinamika struktur dengan berbagai aplikasi kerekayasaan seperti prediksi beban dinamis pada wahana permukaan dan bawah air, prediksi kerusakan struktur, getaran struktur kapal, serta desain buoy tsunami/seismik dan unit dasar laut. 2016 / Rekayasa Desain dan Analisis Struktur perangkat dasar laut Ocean Bottom Unit (OBU) untuk INA – TEWS / Wibowo. Pada sistem ini tsunami buoy akan berpasangan dengan OBU untuk mendeteksi dini kejadian tsunami.
