Abstract

Abstract – Among shipyard repair companies there is a constraint, which is the condition of the workarea that requires a tool or equipment that can be used to accommodate ship access which can reachdifferent height of the deck from the ship caused by tides. Even though there is existing product, theconditions often a fixed stairs which can cause rapid corrosion due to direct contact with the weather.Therefore, based on the mentioned problem, it is necessary to design a new lifting tool that can avoidthose problems. In this research, the new lifting tool design is called an Accommodation Ladder andGangway Portable. This equipment are not fixed and can be adjusted in terms of height whichdirectly can solved the problem at the deck area. Several steps will be carried out which will includedata to be appointed, lifting equipment planning, strength analysis and also the assembly processesfor the prototype. In order to meet the strength of the staircase restraint, it is necessary to analyze thestrength of the structure using the finite element method. After analysis, the FEM stress value wassmaller than the permissible stress, which means that it's acceptable and safe with the ratio of 166.67N/mm2 ? 157.2 N/mm2. For the lifting system in the lifting process, it was planned to use 16x9 1fcWire Rope with a diameter of 10 mm using 2 pulleys with a diameter of 100 mm. This operation usesa manual winch and it can be portable by using the High Duty Wheel.

Abstract – Pressure vessel is a structure which used for fluida storage wheter in gas or liquid form inmany kind of industries. Referred as pressure vessel because the pressure and temperature of thefluida inside the pressure vessel is different compared to pressure and temperature of atmosphereoutside of pressure vessel. This research started with calculating the plate thickness in every sectionbased on internal and external pressure consideration. After that, the next step is calculating themaximum deflection due to wind load and required plate thickness due to seismic load. Finally, thelast step is calculating the stress value that occurs in pressure vessel using hand calculation andANSYS method.The result shows that the largest required thickness based on internal and externalpressure is 0,875 in and 0,1875 in for the smallest. For maximum deflection calculation, the result is0,576 in based on Henry H. Bednar method and 4,09 in based on Dennis R. Moss method. In stressanalysis using hand calculation method, the largest result is 7.416,38 psi and 1.870,44 psi for thesmallest. On the other hand, the largest value of the stress analysis using ANSYS method is 7.832,76psi and 1.994,99 psi for the smallest.

Abstract

Abstract – A packaging industry in Surabaya is engaged in the production of plastic packaging.Based on 2018 data, there is a product that has the largest percentage of defects, namely PT004cover Eva Mulia (12.7%). Primary ex treatment is the most dominant problem among other disabilitycategories with a percentage of 43%. The purpose of this study is to know and identify the factors thatcause the many defects in the primary ex treatment category and determine alternative improvementpolicies that can reduce the rate of occurrence of primary Ex treatment defects. The Six SigmaDMAIC approach (Define, Measure, Analysis, Improve, Control) is done to overcome this problem.3.35 sigma was obtained from the DPMO calculation in the measure phase and from making a pchart type control chart known that the production process is not statistically controlled. From theanalysis of the causes of the problem using FTA (Fault Tree Analysis), there were 4 factors thatcaused the primary ex treatment defect, the non-sterile environment, there was no standard forprimary administration, the primary material was volatile in the open air, and the primary andprinting processes were carried out separately . As well as handling problems using FMEA (FailureMode and Effect Analysis) and several alternative policy improvements, namely determining the rightdose for the primary and ink mixture, combining the primary giving process and printing process,adding the primer is done together with weighing ink, mixing the primer with ink printing at the sametime in a sterile place, and make a work instruction. The results of the 15-day improvement resultedin a value of 3.8 sigma.

Abstract

One way to maximize the engine power of the bore up motor is by modifying the camshaft, so as to get an efficient volumetric. The purpose of this study is to determine the effect of variations in the total duration of the modified camshaft on motor performance. The research method used is the experimental method by varying the modified camshaft with a total duration value of 235°, 236°, and 238° and the standard camshaft with a total duration of 222.5° by testing using a dynotest engine to measure power and torque, burret tube and stopwatch to measure fuel consumption. The results of this study indicate that the modified camshaft with variations in total duration can significantly increase power and torque. The standard camshaft produces a maximum power and torque of 14.27 (HP) and a torque of 12.2 (Nm), while the modified A camshaft produces a maximum power and torque of 16.21 (HP) and a torque of 13.22 (Nm), the modified B camshaft produces a maximum power and torque of 16.84 (HP) and a torque of 13.69 (Nm), and the modified C camshaft produces a power and torque of 16.08 (Hp) and a torque of 13.42 (Nm). In this study it can be concluded that increasing the total duration value can increase power, torque, and fuel consumption.

Abstract

PT. RPC Indonesia produces pipes using the filament winding method. The pipe has shipping standards to ensure it reaches its destination safely, so a packing spacer is made as a pipe safety in the shipping process. Currently, the process of making packing spacers is using the hand lay-up method. This is deemed less effective because of the lengthy manual manufacturing process with poor results, and because it takes workers who only focus on making packing spacers. Therefore, a mandrel that functions as concrete was designed to transfer the hand lay-up process to the winding process using a filament winding machine for the production of packing spacers. The Ulrich method is used in the mandrel design process for packing spacers, starting from the requirements, making alternative design concepts, selecting design concepts, and realizing the design. Based on the results of the design concept, the selected design concept is design concept 2. Next, the process of fabrication and testing of the mandrel and the output produced by the mandrel are carried out. It was found that the mandrel was able to produce 18 pieces of DN100 pipe packing spacers in 8 hours. The output or packing spacers produced from the production process with a mandrel using a filament winding machine are able to withstand a load of 3008 kg. The total budget for making mandrels is Rp. 5,847,000. In future research, it is expected to add a silicone filament separator component that is resistant to high temperatures so that the fiber does not slip due to the presence of resin.

Abstract

The supply of pineapple leaf waste has great potential to provide benefits, other than just being composted or burned. Instead, the process will have an impact on humans and the environment. In addition, the handling of fly ash waste has also recently become a concern. The abundance of them and the lack of utilization add to the series of waste handling problems. Composite technology is one of the waste control solutions. Composite technology helps in the use of wastes as composite materials into new materials, especially in the shipping sector and generally for application in other industrial fields. This research aims to determine the effect of laminate configuration and fly ash substitution on the bending strength of the pineapple leaf fiber-reinforced hybrid composite WR200 as an alternative hull material. The configuration of the laminate was varied, and the effect of the substitution of fly ash as a filler on the composite was also analyzed. The variations used in this study are laminated configurations with fly ash substitution and without fly ash substitution. Composite samples were manufactured using the hand lay-up method with a reinforcement: matrix composition of 30%:70 %. The resulting composite with the highest bending strength of 120.47 MPa in the CWWC laminate configuration without fly ash substitution. The resulting composite can be applied as an accommodation room bulkhead material according to the SNI 01-4449-2006 standard.
