Work accidents according to Heinrich 88% are caused by human factors so that they can be prevented, so improving the behavior of workers becomes very important. The study was conducted on cadets post-sea practice, against the use of personal protective equipment (PPE). The research method was carried out quantitatively by distributing questionnaires to 150 people (75 cadets of nautica and 75 cadets of technics / machines). The results showed that the understanding of cadets on the function and usefulness of PPE when on board was relatively high (90%-90.8%). However, the use of PPE on board is relatively low (83%-84.8%). So it can be concluded that the understanding of cadets against PPE is high enough but still reluctant to use it completely and correctly. The reason they did not use, because PPE is not suitable to use due to poor maintenance. For that to the management of the ship to carry out routine maintenance, so that PPE can be used to the maximum extent possible.

Ketel uap bantu di kapal merupakan salah satu permesinan bantu yang memiliki perananpenting untuk menghasilkan uap panas yang berkualitas. Kegunaan dari uap ini adalah untukmemanaskan bahan bakar, ruangan, zat cair dalam tangki, fresh water jacket cooling,menggerakkan pompa turbin dan lain sebagainya. Agar menghasilkan uap yang berkualitas dandalam jumlah banyak maka dibutuhkan pembakaran yang sempurna pada ketel uap bantu.Penelitian ini dilakukan di kapal MT. Enduro. Sumber data yang diperoleh adalah data primeryang diperoleh langsung dari tempat penelitian serta data sekunder yang diperoleh dariliteratur-literatur yang berkaitan dengan judul penelitian. Hasil kerja yang diperoleh daripenelitian ini menunjukkan bahwa tidak optimalnya pembakaran pada ketel uap bantudisebabkan karena temperatur bahan bakar yang tidak sesuai yang disebabkan oleh rusaknyaheater, kurangnya suplai udara disebabkan oleh rusaknya elektromotor, macetnya fire damperdisebabkan oleh rusaknya magnetic contactor, nozzle burner kotor disebabkan oleh bahan bakaryang masuk ke dalam nozzle burner tidak melalui proses pemisahan di dalam purifier.

Abstract. The commercial vessel uses sea water to stabilty a vessel when the vessel is not loading a cargo. The water stabilized for the vessel is known as ballast water. The activity of loading the ballast water for the ship from origin port and dissposal to the distination port has caused impact on spreading the unidenfied organism the local port. Aim of the study to determine disposal value of water ballast either from a foreign merchant vessel or domestic merchant vessel so that Port of Tanjung Emas Semarang (PTES) is able to determine a policy on ballast administration from merchant vessel include a data of Arrival and Departure Report of the Vessels (ADRV) documents for the last five years (2009)(2010)(2011)(2012)(2013)(2014). Disposal ballast water of domestic vessel to PTES is average about 37,036 m³ and increased by 76.68% in a year. Yearly ballast water disposed from the foreign commercial vessels has reached 576.045 m3 for the last 5 years. The increasing of ballast water is about 122.19%. Level of vunerability on the PTES waters is due to ballast water dissposal caused mainly from foreign commercial vessels. The PTES administration should provide water reservoir and and water ballast treatment of commercial vessels which has 51,090 m³/per month or 81,744 kl/month.

This article aims to analyze the policy strategies implemented for the commercial shipping development of the Apo Dock in Jayapura port to improve port performance towards strengthening the sea highway program. Apo Dock as a shipping commercial in Jayapura port has weaknesses as identified by the observation and the study of primary data. These weaknesses have resulted in price disparities for the Papua province as port functions well as a logistical hub. Based on the Strengthen-Weakness-Opportunity-Threats (SWOT) analysis results, it was concluded that the Apo Dock performance as the Jayapura Port Commercial Route was in quota I with a position (0.83; 1.44). The strategy used by Jayapura port to develop commercial shipping to be more efficient in accordance with its function as the strength-opportunity (SO) strategy. The SO strategy strengthens the commercial shipping function as a support base for the economic development centers and a government supporter in MP3EI, the commercial port facilities and infrastructure development were established in order to support all port activities and efficiency, and develop hinterland areas to maximize the busy and crowded commercial shipping hub.
