Abstract

The outboard motor mount is an important piece of equipment when building an outboard motor workshop or laboratory. The outboard motor mount is needed because it is not possible to learn about the motor components with the motor attached to the hull of the boat. Therefore, it is necessary to design an outboard motor holder that fits the lot size and can be moved to facilitate the testing of the outboard motor in the test pool located outside the laboratory building. The design is carried out by making 3 models of the seat frame using the Ulrich method and Finite Element Analysis to analyze the strength of each concept. Rapid Upper Limb Assessment is used to analyze the ergonomic aspects of the three concepts. Based on Finite Element Analysis, it is known that the safety factors of concept 1, 2 and 3 are 1,985, 1,689 and 1,860 respectively. The results of the Rapid Upper Limb Assessment analysis show that the three concepts have a final score of 3. Based on the priority scale table with the criteria of evaluating manufacturing costs, ergonomics, flexibility, mass, ease of manufacture and ease of assembly, score concept 1,2 and 3 are 24%, 25% and 29% repectively. From this value, the selected concept is concept 3 as shown in the detailed drawing attachment A.

Abstract

Indonesia is a maritime country so that ships are transportation that supports economic movement. The government's policy of prioritizing the maritime sector in national development has a positive impact on the domestic shipping industry. The shipping industry over time considered the use of composites as a substitute for wood. This innovation is expected to be environmentally friendly because it is a way of treating waste. The lack of use of coco fiber and fly ash as plantation waste and industrial fuel combustion can be used as opportunities for new environmentally friendly raw materials. It is necessary to use coconut fiber as an alternative natural fiber to synthetic fiber as a reinforcing element from fly ash as a filler in the manufacture of composites. Coconut coir fiber as a reinforce was delignified using 5% NaOH for 120 minutes to reduce the lignin content in the fiber. Analysis of the strength of mechanical properties through tensile tests in accordance with ASTM D638-14 on composite specimens with variations in the addition of reinforcement as much as 10% and 30%, and various variations in the percentage of adding fly ash of 0%, 5%, and 15% to the reinforce. The variation of the composite mixture to the highest tensile strength was obtained by adding 30% reinforce. Specimen 9 with fly ash filler of 15% produced a tensile strength of 27.09 MPa. The mixture of adding reinforcement and filler substitution in coconut fiber composites has a strengthening effect on the tensile strength of the composite. The resulting composite can be used for bulkhead wall material for ship interior accommodation in accordance with SNI 01-4449-2006 regarding fiberboard.

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.

Abstract

Aerators play an important role in maintaining shrimp survival in aquaculture ponds. To improve aerator performance, good quality and durability floats are required to support the optimization of aerator loads. Because aerators operate in open areas exposed to sunlight, there is a possibility that aerators will degrade due to exposure to ultraviolet light from the sun. Therefore, this study reviews the impact of ultraviolet light on the decrease in tensile mechanical properties and changes in functional groups in float materials made of HDPE. Tensile test samples were replicated three times in each variation to obtain reliable experimental results, then FTIR testing was performed. The results show that the sample with the highest exposure has the largest decrease in tensile strength, which is about 14%. Based on FTIR analysis, ultraviolet radiation does not reduce functional groups, but reduces the intensity of each functional group. HDPE has an approximate service life of 1664 days.

Abstract

Corrosion of paddle wheel aerator gearboxes is a major factor affecting their performance in shrimp farms. To maintain its performance, protection from corrosion of the gearbox is necessary. This study focuses on the effect of nickel electroplating on corrosion rate. Electroplating is a way of coating metals with electric current. The variations used were electroplating current and time, then analyzed using the weight loss test. The results showed that the thickest coating occurred in the variation of 4A and 30 minutes, about 1.03 mm. The thinnest coating occurred in the 1A and 10 minutes variation, which was 0.10 mm. The lowest corrosion rate is at variation 4A and 30 minutes, which is about 0.1655 mmpy. The highest corrosion rate was in the 1A and 10 min variation, which was about 0.4246 mmpy. The greater the electroplating current and time, the more the service life of the coating increases. The conclusion of this research is that nickel plating by electroplating can reduce the corrosion rate of the aerator gearbox by about 92%, because the corrosion rate of the coated one is lower than the uncoated one.

Abstract

Spot welding technique is one of the most important parts in the train manufacturing process, especially in the plate working stage for the train carbody. This research aims to see the parameters that affect the tensile strength of the spot welding results using the Taguchi Method on SUS 304 2 mm and DIN 1.4003 3 mm welding joints. The parameter variations performed in this Taguchi Method are current strength, welding time, and electrode diameter. While the control level used is 2 levels on Strong Current 10.5 kA and 11 kA, Welding Time 20 cycles and 25 cycles, and Electrode Diameter 6.5 mm and 12 mm. The results obtained after analyzing and processing the data are the most influential parameters, namely strong current, followed by welding time, and the smallest influence is the electrode diameter. The results of the optimum parameter combination in this study are Current Strength 11 kA, Welding Time 25 cycles, and Electrode Diameter 11 mm. The combination of these parameters has been proven in confirmation of experiments with the Taguchi Method at a confidence level of 95% in the interval of confirmation experiments.

Abstract

UT Surabaya has a warehouse for storing spare parts needed either during heavy equipment maintenance work or customer demand in purchasing spare parts. This warehouse still does not maximize the existing capacity, seen from the many spare parts that are not arranged. This is due to the lack of shelf storage capacity due to the demand for many spare parts. In addition, the placement of spare parts that are not organized according to their group creates one of the problems, namely oil leaks that hit other spare parts. Seeing these problems, it is necessary to design a warehouse rack supported using the Ulrich Method by making three design concepts for selecting the most appropriate concept and in accordance with warehouse needs. Making design and structural strength analysis using Fusion 360 Software based on Finite Element Methods. The selected concept is design concept 2 with structural strength analysis of the rack frame obtained the results of allowable deformation of 1.37 mm for manual calculation and software displacement analysis obtained the maximum value that occurs 0.3670 mm with ASTM A36 material deformation allowance of 23.87 mm. The maximum stress value of 45.82 MPa in software analysis and 45.64 Mpa in manual calculations with ASTM A36 material allowable stress limit of 166.667 MPa. Then the maximum safety factor value of 5 is obtained, which means the machine frame is safe to use. total
