Abstract

Siwa Ferry Port with 3 units of ships, namely KMP New Rose, KMP New Camellia and KMP Merak, with the Siwa - Tobaku crossing service having an important role for regional development in Wajo Regency and several surrounding areas. In managing the Siwa Ferry Port, the Regional Government of Wajo Regency as the port operator, together with the Region XIX Land Transportation Management Center of South Sulawesi and West Sulawesi Provinces as regulator functions always supervise aspects of safety, security and order. The research method used is direct observation in the field (Field Research) by measuring the distance between vehicles and lashing tools as well as literature/documentation. This research analysis is guided by the Regulation of the Minister of Transportation Number 115 of 2016 regarding Procedures for Transporting Vehicles on Ships and the Regulation of the Minister of Transportation Number 30 of 2016 regarding Obligations to Bind Vehicles to Crossing Transport Vessels. The analysis that will be used is the analysis of vehicle weighing equipment needs, analysis of vehicle placement on ships, analysis of vehicle loading space cleanliness, analysis of the distance between vehicles, analysis of vehicle loading space sterilization from passengers, analysis of vehicle binding and analysis of administrative sanctions to ship operators. Based on this analysis, it was concluded that the conditions of transportation at the Siwa ferry port are still not in accordance with the Regulation of the Minister of Transportation Number 30 of 2016 and Regulation of the Minister of Transportation Number 115 of 2016 in terms of vehicle binding, range between vehicles, sterility of loading space from passengers and spills of grease and oil, availability of fasteners and binding officers.

Abstract

The lubrication system on the main engine plays a crucial role in maintaining optimal engine performance during operation. Its function is to lubricate moving engine components, lower engine temperature, reduce vibration, and protect core components from corrosive substances so that engine performance will always be maintained and can support the smooth operation of the ship, from the researcher's observation of the mother machine in KM. Tonasa Lines found that the main engine had a problem with the lubricating oil part, namely the dropped lubricating oil pressure. This study is directed to determine the cause, impact of the pressure drop, and handling steps so that the main machine can work normally again. This study applied the FTA (Fault Tree Analysis) method to understand the causes and effects of decreased lubricating oil pressure. The results showed that the decrease in lubricating oil pressure was caused by a pump not functioning optimally and blockages in the lubricating oil filter. This results in inefficient lubrication of the main engine. Decreased lubricating oil pressure that reaches 2.0 kg/cm2 increases the main engine's temperature. The recommended solution to restore the lubricating oil pressure to the normal pressure of 3.0 kg/cm2 is to add lubricating oil to the degraded/reduced Lubricating Oil Tank. In addition, it is important always to ensure the cleanliness of lubricating oil filters, monitor pump RPM through routine maintenance, and document any incidents in log books.
