The underground rock is composed of rock skeleton and pore fluids. When seismic waves propagate in underground medium, it will show complicated change influenced by pore and pore fluids in rocks. It is very important to study the characteristics of reflec... see more

The quantification of the reflection of water waves is of paramount importance in coastal and marine engineering. Reflected waves are produced as a result of an incident wave meeting a reflective boundary e.g., in a wave basin. While reflection can be see... see more

In planning the construction of a seawall, it is necessary to consider several things, such as incoming waves, types of defensive units, and economic factors. So planning for the type and size of the armor unit used, it is expected that the structure will... see more

An accurate mapping of ocean seabed is needed to answer the challenges faced by the marine scientist today. Sub-bottom profiler present as one of the acoustics system which used to describe the sediment layer profile of the ocean bottom, as well as the th... see more

The table tennis game table can be made of any material with certain bounce height requirements according to ITTF regulations. Wood as the main material for the table is found in Indonesia. Various types of wood have the potential to be a dining table mat... see more

The development of cellular technology has now entered the 5th generation (5G), this 5th generation provides 3 types of services, eMBB (enhanced Mobile BroadBand), URLLC (Ultra-Reliable and Low-Latency Communications) and mMTC (massive Machine Type of Com... see more

This paper presents an experimental study on wave reflection from submerged rectangular objects (shelves) in a 2-D laboratory flume. Preliminary tests using resistive wire probes and an acoustic Doppler anemometer were first conducted to confirm that a pi... see more
