design on fuel oil system to support the performance of the main engine on board mt.
calypso 7”
The use of Heavy Fuel Oil (HFO) as the main fuel of the ship requires proper viscosity
management to maintain the efficiency and reliability of the main engine. This thesis
discusses the development of an Arduino Uno R3 CH340-based viscosity sensor
prototype on the MT. Calypso 7 to support the performance of the main engine. The
problem raised comes from the author's direct experience during sea practice, where there
is instability in fuel viscosity which has an impact on incomplete combustion and engine
damage. This research uses the Research and Development (R&D) method to design,
build, and test the developed tool. The prototype integrates a DS18B20 temperature
sensor, a KY-003 Hall Effect sensor, a 775 DC motor, and an LCD module for real-time
viscosity monitoring. The validation test results show that this tool has a feasibility level
of 91.4% and is included in the “very suitable” category. Thus, the developed tool is
proven to be effective and practical in helping control the viscosity of fuel to improve the
performance of the ship's main engine.
