Batam City, which is part of the Riau Islands province, a connecting city between Indonesia and Singapore. City located in very strategic location border region countries, neighboring one world's business centers, namely For this reason, marine transportation has important role maritime countries like Indonesia. The high intensity Singapore cannot be separated from Chinese population community ...

To evaluate a rapid and cost-effective method for monitoring bacteria in ballast water, several marine bacterial isolates were characterized by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Since International Maritime Organization (IMO) regulations are concerned with the unintended transportation of pathogenic bacteria through ballast water, empha...

The connecting rod is a critical part inside the marine engine. The inspection of its important parameters is directly related to the assembly and quality of the marine engine. A coordinate measuring machine (CMM) is a conventional choice to measure the parameters of a connecting rod. However, CMM requires significant resources in time and cost, which leads researchers into in-situ measurement....

Shipmasters may have to perform unberthing without tugboat assistance when a tsunami warning is issued. Keeping this in mind, we studied emergency unberthing without tug assistance by conducting numerical simulations and full‐mission ship maneuvering simulator (SMS) experiments. A panamax class medium‐sized bulker and a pure car carrier (PCC) were used as test ships. In the...

The relevance of simulation as a teaching tool for medical professionals working in rural and remote contexts is apparent when low-frequency, high-risk situations are considered. Simulation training has been shown to enhance learning and improve patient outcomes in urban settings. However, there are few simulation scenarios designed to teach rural trauma management during complex medical transp...

With increasing marine transportation and logistics, the ship autopilot has become much more important not only to lower the seaman's operating intensions, but also to reduce the seaman's deployment. It is still a challenge to design ship coursekeeping controller because of ship's uncertain dynamics and time-varying environmental disturbance. This study focuses on backstepping adaptive course-k...

Hull form optimization from a hydrodynamic performance point of view is an important aspect of ship design. This study presents a computational method to estimate the ship seakeeping in regular head wave. In the optimization process the Genetic Algorithm (GA) is linked to the computational method to obtain an optimum hull form by taking into account the displacement as design constrain...
