Abstract: PT Pelabuhan Indonesia (Persero) is one of the gateways for ships and goods both domestically and export-import. In the operation of the Rubber Tyred Gantry (RTG), several cases of problems were encountered that could hinder or disrupt the loading and unloading process caused by the incompatibility of the maintenance schedule provided by the company for the equipment used. The purpose of this study is to determine the time schedule for the maintenance interval of the Rubber Tyred Gantry unit on critical components that often experience damage, and determine a maintenance strategy to anticipate sudden damage to critical components. This study uses the Reliability Centered Maintenance (RCM) II method with critical component analysis using Failure Mode and Effect Analysis (FMEA). The results of this study are maintenance intervals based on the RCM II Decision Worksheet for critical components that have potential failures, including Engine components with preventive maintenance intervals every 16 days a month or 23 times a year, Spreader components with preventive maintenance intervals every 10 days a month. or 36 times a year and Trolly Brake components with preventive maintenance intervals every 13 days a month or 28 times a year during machine operating hours and Strategies to reduce damage to RTG units based on the RCM II Decision Worksheet on RTG unit maintenance using a preventive maintenance strategy by a combination of corrective maintenance where preventive maintenance is carried out according to a predetermined maintenance interval schedule and corrective maintenance is carried out by preparing spare parts that must be replaced when carrying out preventive maintenance checks.

Abstract: Comfort Zone is a psychological state when things are familiar and people feel they are in control and hence experience less anxiety. However for a person to grow the person must step out of comfort zone into an optimum performance zone. What is true for persons can be true of an academic discipline. Industrial Engineering, which essentially means Optimisation, is currently in comfort zone of office/factory/shop set up. Industrial Engineering must step out of this familiar set up and get into everything, everywhere and every time. Getting out of comfort zone is scary, but not so hard. And indeed being out of comfort zone is what will ensure growth and eventual success. No growth can happen by staying with familiar. Scientists and Inventors have to step out of comfort zone. Explorers had to step out of comfort zone to discover new continents. If humans had not step out of comfort zones we would not have had aeroplanes or ships for that matter. Academic discipline also has to move out of comfort zones to grow. Some of obvious instance of an academic discipline growing by stepping into interdisciplinary mode is Biotechnology, or Process Control that borrows from Electrical engineering and Computer Science as much as from Chemical Engineering.

Abstract: The problem of determining the efflux time for tanks of various sizes, shapes, and purposes has received significant attention by engineering literature. Models developed are typically situational, and prove useful in very specific scenarios. Few of these models however, take into consideration tanks with pipe fittings or some kind of tubing aligned. Traditional investigations focus on efflux times of tanks with open orifices, through the usage and manipulation of Torricelli’s law. This essay deals with tanks that are connected to pipes, and how the friction between the fluid and pipe walls impedes the usage of Torricelli’s law and requires more advanced models. The principal objective of this essay is to develop a model that describes the efflux time of tanks with pipe fittings by investigating its relationship with fluid velocity and flow rate. This includes usage of Bernoulli's Extended equations and undertaking the assumptions of pseudo-steady state flow. The computer software MATLAB will be used to develop the efflux time model and other complex differential equations. The model developed by the paper is then compared to other models in literature, in terms of accuracy of prediction. The most significant conclusion arrived at is that ignorance of minor losses advances the argument over its significance when dealing with the efflux of tanks, and must be considered in any new models in the future.
