Abstract

This study aims to analyze the factors that affect the stability of ships in MV. Sumatra Leader. The research was carried out for 12 months, from 9 February 2023 to 9 February 2024. This research was carried out on a pure car carrier or Ro-Ro ship named MV. Sumatra Leader, owned by NYK Spill Indororo, Ltd. The data analysis technique of this study is qualitative, using a descriptive approach. The subject of the study was five ship crews consisting of the Captain, Chief Officer, Second Officer, Bosun, and Foreman. The data collection technique is in the form of direct observation and interviews with the research subjects. The results of this study show that the factors that affect the ship’s stability are cargo arrangement, cargo space optimization, cargo handling techniques, the presence of ramp doors, ballast arrangements, a good stowage plan, ship drafts, and correct GM calculations. It is recommended to check the clinometer periodically, tie the cargo well and firmly so that it does not shift, arrange the cargo according to the stowage plan, and do GM calculations to get a positive and ideal GM of the ship after the loading is completed to maintain the stability of the ship when sailing.

Abstract

The study has been conducted on the water quality level of the Babak River around Kebon Kongok landfill, Lombok. This research was conducted considering that water has many benefits in the daily lives of people. This research uses an experimental method by analyzing physical parameters (temperature, conductivity, pH, and total dissolved solids (TDS)), and chemical parameters in the form of heavy metal content lead (Pb), iron (Fe), manganese (Mn), and copper (Cu)). Analysis results were compared with quality standards based on Ministry of Health Regulation No. 32 of 2017 concerning water quality. Based on the study, it was found that the farther the distance of water measured from the source of pollution, the value of the physical and chemical parameters of water will be smaller. Most of the physical parameter test results show the Babak River water quality is still at the safe threshold limit but there is 1 point of river water that is polluted due to the distance that is too close to the active zone. Chemical parameters show the results of heavy metal content below the threshold limit. Analysis of the water quality shows that the water is still in good condition, which is below the threshold set by the Indonesian government.
