Pengukuran Titik Stabilitas Secara Melintang Kapal Dengan Percobaan Kemiringan Simulator Stabilitas Kapal Berbasis Mikrokontroler Arduino

Abstract

The stability of the ship in various conditions during the addition, reduction or transfer of cargo and during the voyage can be calculated by knowing the initial stability conditions of the ship in advance. In general, the initial stability of the ship is limited to transverse stability. This means that the transverse stability line of the empty weight of the ship must be known in advance by carrying out a slope experiment. Conventionally, the slope experiment is carried out using a pendulum on the CL line. This study discusses the identification of the transverse stability line of the ship through a slope experiment using Delphi programming based on an Arduino microcontroller which functions as an inclinometer. The level of accuracy of the inclinometer is calculated by comparing it with a pendulum and a protractor which functions as a reference angle measuring instrument. With an experimental angle of 0°-5° and a protractor as a reference angle measuring tool. The results of calculations using the model obtained BM 3.23 cm; GZ 0.61 cm; GM 0.38 cm; KG 0.50 cm; RM 0.18 cm. The difference in the test results of the tilt angle experiment may be due to an error in the scale reading on the ship model.
