Abstract

Corrosion happens differently for each point of hull plate which caused of corrosion rate differences. So that is very important to measure it for each point, which is calculated using Weight Gain Loss Method. The measurement of plate thickness that used is Ultrasonic Test Method conducted by PT BKI. To determine the condition of ship protection, then the coating and sacrificial anode system is evaluated by testing the composition and current and voltage of anode as well. Furthermore, the number and position of anode is also analyzed. So that the re-design of cathode protection is needed by referring to the PT BKI’s standards. Then the prediction of corrosion rate is calculated by using the design of cathode protection. The largest corrosion rates are in the amidships and portside for each plate lane, they are on the keel plate point K3 is 0.37 mm/years, pedestal plate point A4 is 1.05 mm/years, bilge plate point B4 is 0.62 mm/years and side plate point C5 is 0.39 mm/years. But the number of installed anode is 31 anodes with an irregular position. So in this study, done the redesign system of cathode protection based on regulations issued by PT BKI, with the result of the number of the anode is 56 units. Using the design, then carried a prediction by the result is lower, that on the keel plate is 0.073 mm/years, pedestal plate is 0.021 mm/years, bilge plate is 0.013 mm/years and the side plate is 0.014 mm/years.

Abstract

In this study, the manufacture of composites using the powder metallurgical method used two research variables, namely the rate of heating with variations in temperature with an increase of 3°C/minute, 5°C/minute and an increase of 7°C/minute.  The second variable is the mixing composition with variations in aluminium composition: Fly Ash is 100%:0%, 85%:15%, 80%:20% and 75%:25%.  The highest hardness results in this study were found in the 15% fly ash composition with a heating rate of 3°C/minute where the hardness value was 66.17 HRF while the lowest hardness value was found in the 0% fly ash composition with a heating rate.  of 7°C/min with a hardness value of 34.84 HRF.  For compressive strength test results.  the highest value was obtained in the 15% Fly Ash composition with a heating rate of 3°C/minute where the compressive strength value was 106.78 MPa, while the lowest compressive strength value was in the 0% fly ash composition with a heating speed of 7°C minutes where the value was 42.71 MPa.  From the hardness and compressive strength value, it can be concluded that the smaller the heating rate, the higher the hardness and compressive strength and the greater the SC mixing composition, the higher the hardness and compressive strength.

Abstract

Kaizen is a concept of continuous improvement that emphasizes quality enhancement and efficiency in production processes. In this study, the Kaizen approach was applied to address dimensional defects in the welding process of the Fender D155A-6R component at PT. Arkha Jayanti Persada. The component, which was previously imported from Japan, is currently being tested through local production trials. Initial inspection indicated that 11 of 33 measurement points were out of tolerance, most of which were linked to welding activities. To analyze the problem, the PDCA (Plan, Do, Check, Act) cycle was employed. The investigation revealed several contributing factors: the absence of a locator to secure parts during welding, insufficient reinforcement that caused deformation, and the lack of a standardized welding procedure for operators. Corrective measures were then introduced, including the installation of a locator, additional reinforcements, and the establishment of a formal welding procedure. After two PDCA cycles, the dimensional issues were successfully resolved. The findings indicate that applying Kaizen through PDCA led to significant improvements in dimensional accuracy and product quality.
