In order to maintain its stability, commercial ships use ballast water as a
medium to maintain the stability of the vessel. Water ballast exchange is required
as a preventive measure to avoid damage to ecosystem in a region, especially in
writing this mini thesis that port of Baltimore, USA. The purpose of this mini
thesis is to know about how the operation of water ballast exchange, the impact of
water ballast disposal, and eliminating the constraints in the implementation of
water ballast exchange. In writing this essay, the authors describe the theory of
water ballast exchange as a foundation for solving existing problems.
The method used in this research is descriptive (when viewed from the
aspect of presentation level) and also qualitative (when viewed from the way of
data processing), then analyzed with fishbone analysis method to determine the
problem of each factor and technique of data analysis ultrasound (Urgency,
Seriousness , Growth) to determine which issues are the top priority. In this case
the technique of collecting data in the form of approach to the object through
observation, interview directly to the subject and using documents and data
related to the process of water ballast exchange.
From the results of the research, there were found problems in the
preparation of the implementation and the equipment which includes the activities
of the cause not implemented, the obstacles not implemented, and the effect on the
stability of the ship. Chief officer as an officer responsible for this activity should
be more assertive, especially in training and supervision. Equipment maintenance
is not routine, and the implementation of water ballast exchange is not in
accordance with the procedure resulted in water ballast exchange process is not
running effectively and efficiently. As for the suggestion of the author of the
company also play a role by conducting guidance or training to crew that will go
aboard and also at the time aboard by chief officer, applying technology of AOT
(Advance Oxidation Technology) that can kill dangerous microorganisms and
standard operational procedure (SOP) that is clear on board. So it can be done
well according to the rules set by the water ballast management convention.
