Abstract

Seawater corrosion is one of the main causes of damage to the hull and hull of the ship, which can reduce the strength, service life, and safety of the ship and crew. To prevent losses due to corrosion, protection of the hull plate is required through two methods: passive protection (coating) and active protection (cathodic protection). A commonly used method in active protection is the victim anode system, in which more reactive metals are sacrificed to protect hull metal. The anodes that are often used are zinc (Zn) and aluminum (Al). This study aims to evaluate the efficiency and effectiveness of the anode system installed in KRI TJA-541, by comparing the needs of the victim anode from a technical and economic perspective, as well as the results of theoretical calculations based on the DNV RP-B401 standard. The observation results showed that the thickness of the coating of KRI TJA-541 ranged from 150-250 ?m, which is included in category II (DNV RP-B401), with a Zn anode requirement of 439 kg or Al 153 kg. Currently, 1424 kg of Zn is installed, which shows that the use of the DNV RP-B401 standard with aluminum (Al) anode is more technically and economically advantageous.

Abstract

One of the defense equipment that determines the readiness of the Navy in maintaining the integrity of the Republic of Indonesia is the Republic of Indonesia Warship (KRI). The worthiness of the KRI is of course the main parameter that is always integrated with the condition that it is always ready to fight to maintain Indonesia's sovereignty at sea . The readiness of the KRI is assessed from the aspect of equipment feasibility as a benchmark to determine the level of readiness and capability of the warship. This research aims to analyze the concept of increasing the competence of the Navy surveyor personnel. The research method used is the AHP and SWOT methods. The results of the study indicate that the appropriate strategy to be applied by the Navy in order to achieve sustainable competitive advantage is by : a ) increasing the competence of the Navy with formal and informal course activities, b ) increasing cooperation with external institutions, c ) increasing standardization socialization. operational test equipment to increase the ability to operate test equipment owned by the Indonesian Navy's airworthiness personnel, d ) add equipment in accordance with the update on the development of defense equipment, and e ) improve the coaching program for both tour of duty and tour of area.
