PENGARUH MODIFIKASI DAN TATA LETAK KOMPONEN TERHADAP TINGKAT KEBISINGAN KAMAR MESIN KMP. MERAK

Noise in the ship's engine room is one of the factors that can affect the comfort and safety of the crew. This study aims to analyze the effect of component layout modifications on noise levels in the engine room of KMP. Merak. The method used in this study is a quantitative approach by measuring sound pressure levels at several points determined before and after modifications and changes to the component layout. After remapping and modification of the component layout, there were significant changes in the distribution and intensity of noise. Under conditions when the ship is sailing with both main engines and one generator unit active, there is a decrease in Leq value of 4.93% in modifications 1 and 2, and 4.43% in modification 3. Meanwhile, under conditions when the ship is anchored with both main engines inactive and one generator unit active, the noise reduction recorded is 6.79% for modification 1, and 8.01% for modification 2, and 7.71% for modification 3. These results indicate that modifications to the component layout provide an effective contribution in reducing and suppressing noise levels in the ship's engine room, resulting in a more controlled acoustic environment at a lower level.
