Abstract

The shipping industry plays a vital role in supporting passenger mobility and goods distribution in Indonesia. However, one of the challenges faced is the management of crew working hours and rest periods, particularly in relation to shore leave activities. This study aims to analyze the effect of crew shore leave on the effectiveness of watchkeeping duties on passenger ships and the impact of crew shore leave on the readiness and performance of watchkeeping crews. The research method used is a quantitative approach with an instrument in the form of a questionnaire distributed to 35 passenger ship crew members on duty at PT Pelni Makassar. The data were analyzed using descriptive statistics, regression tests, and ANOVA. The results of the study indicate that shore leave crew has a significant effect on the quality of watchkeeping, particularly in terms of physical readiness, mental readiness, and reduction of fatigue risk. These findings emphasize the importance of good shore leave schedule management to support shipping safety.

Abstract

The blasting process in the shipping sector aims to remove dirt, rust and factory scale from the plate surface and to create roughness on the surface so that the paint layer can adhere well. In the blasting process, abrasive materials are generally used once or twice. However, in field practice, reused copper slag has been used as an abrasive material. This study aims to analyze the surface roughness level of the plate during the blasting process using the Analysis of Variance (ANOVA) method with variations of new copper slag, reused copper slag 1 and 2 with cleanliness standards according to ISO 8501-1 SA 2.5 and the standard surface roughness level of the plate according to IMO-PSPC (Performance Standard for Protective Coatings) with a surface roughness level ranging from 35 µm – 75 µm. From the results of the data analysis, it shows that the reuse of copper slag during the blasting process, the roughness level obtained is getting smaller. Therefore, the surface roughness level of the plate that meets the IMO-PSPC standard which ranges between 35µm-75µm is copper slag reuse 2 and while the maximum limit of the surface roughness level of the plate that meets the IMO-PSPC criteria is copper slag reuse-3.
