Abstract

The study of the characteristics of the underwater acoustic wave propagation pattern which includes temperature, salinity and sound speed can be used to detect the presence of submarines. In general, submarines through or hide in shadow areas (shadow zone), which is an area that is not traversed by the propagation of acoustic waves. By knowing the position or area, it can be mapped submarine traffic area. The Monterey - Miami Parabolic Equation (MMPE) program is used to simulate the acoustic wave propagation pattern, which has previously been tested using the Ray Tracing (high frequency) and Normal (low frequency) methods. This study chose the Lombok Strait as a research locus because the area has complex oceanographic dynamics with the meeting of water masses from the Indonesian Ocean and the Pacific Ocean. Simulations are carried out in 2 seasons namely the West and East seasons (2015-2016). The first simulation of acoustic sources was placed on the island of Bali and propagated to the East. Simulation II of acoustic sources on Lombok Island and the direction of propagation to the West. Simulation III of acoustic sources on Bali Island and propagating to the Southeast, and IV Simulation of acoustic sources on Lombok Island and direction of propagation to the North West. From the simulation results show the formation of shadow zones in all research stations except at the PPSL 15 station and STN 10 station. The submarine traffic lane map is made based on the shadow zone area formed, and the determination of the installation site of submarine monitoring equipment is determined based on the minimum area / there is no shadow zone. The area is the area between STN 10 and PPSL 15 stations with coordinates A (8,746 S - 115,622 T), B (8,746 S - 115,819 T), C (8,750 S -115,624 T) and D (8,750 S - 115,814 T)
