Surging is a phenomenon in which the airflow back toward of the compressor side. This case is known by excessive sound or vibration in the turbocharger. The main cause of surging phenomenon is divided into two types, that is failure operation by crew and improper selection turbocharger by the designer. This research identifies the effect of surging on twisting moment of turbocharger shaft ABB type VTR 354 on Niigata 8MG40X engine. The method is using simulation based on Finite Element Method (FEM), start from determining the compressor and turbine torque then preparing the turbocharger shaft and simulation with SolidWorks. It is found that critical area caused by surging is located on compressor seat. The largest torque difference at 50% of the engine load about -1.304 Nm and maximum stress is about 0.015906 Mpa, while the displacement is about 0.0000270028 mm and the maximum strain is about 6.26693e-008 mm/mm. Thus, the shaft material 17NiCrMo6-4 is considered capable of dealing with surging on the turbocharger.

Publisher : Institut Teknologi Sepuluh Nopember

The dredging of the canal water intake at PLTGU Grati is an effort to maintain the depth of the reduced canal due to sedimentation. The dredging process itself uses a cutter suction dredger. To distribute mud or slurry (a mixture of water and sand) result of dredging to dumping area of PLTGU Grati using HDPE (high-density polyethylene), as pipe material, hence pipe does not wear due to corrosion but erosion. Basically, erosion is caused by impact of solid particle (sand) which is suspended inflow (multiphase) on a solid wall boundary. Wear caused by erosion itself is recognized as one of the problems in some industries that distribute slurry in their process. This research thesis analyzes and predicts the rate of erosion occurring in HDPE pipes that are transported slurry from the sedimentation dredging in PLTGU Grati using CFD (computational fluid dynamic) method. Variations of slurry concentration, impact angle, particle diameter and velocity of the slurry has been be performed to determine the effect on the rate of erosion. The results of this research thesis showed that the concentration of slurry, impact angel, diameter of particle and the concentration of the slurry were directly proportional to the rate of erosion on the HDPE pipe.

One of the parameters that affecting efficiency of container terminal is dwell time (DT). The more least the DT the more efficient a container terminal would be. As the government regulations of the Ministry of Transportation that stated in Number PM 25 in 2017 in Article 2 Paragraph 1 explains that the maximum dwell time must not exceed than 3 days. The purpose of this study is to identify the major factor of prolonged DT in a container terminal. The authors used discrete event simulation to model the system inside the container terminal operation by using Arena Simulation software. The Root Cause Analysis (RCA) is being used for the data analysis and finding the root cause. The container handling inside the container terminal data is collected, then the effect container of handling the equipment on dwelling time was testified by creating a model then analyzed. The result of the simulation is that there is a small impact from container handling equipment towards DT. From the Problem Tree framework that created based on the operational data and interviews. It shows that the most DT is contributed by the prolonged time of container stay at container yard.
