Abstract

Testing is an experiment to know the change of mechanical properties and micro structure in JIS G 4051 S 15 C series steel which is previously was cooled with some variation of media such as immersion into water, oil and cooling in free air then the test include: chemical composition, hardness , Impact, Fractography and Metallography. From result of testing the chemical composition with main integer element got result: 0.15% C, 0.157% Si, 1.2% Mn, 0.01% P, 0.02% S. Hardness test results with Vickers method obtained 183 HV for original test object (original) , 182.66 HV for water-cooled test specimens, 190.33 HV cooled with oil and 196.33 HV cooled with air. While in the impact test the toughness value is 0.5 Joule / mm2 for the original test object, 0.39 Joule / mm2 water-cooled test specimens, 0.56 Joule / mm2 oil-cooled specimen, and 0.61 Joule / mm2 cooled test object With free air. In Fractography testing can not be further analyzed the type of fracture, because the photo does not showed the form of cracks or fault plot. While the metallographic results for the original test object or non heat treatment structure is Ferrite and Pearlit, after Hardening the structured remains Ferrit and Pearlit, there is a change in the structure form into Martensit. The mechanical properties generated after the testing process on the JIS G 4051 S 15 C steel have increased the toughness and decreased the hardness so that the steel can be summarize to be more resilient than the original.

Abstract

The analysis of the resistivity of a wire based on the Wheatstone bridge method and the Ohm law method in physics experiment module has been done. The analysis of the resistivity of a wire was done in a physics laboratory at UPNVJ engineering faculty. This topic was studied because there has been no experiment in the themed of electricity in the physics experiment module at the faculty of engineering UPNVJ. The most popular method applied to obtain wire resistivity value is the Ohm law method. In order to enlarge the understanding of the electricity concept, this research needed other method that can be used to find out the wire resistivity namely the Wheatstone Bridge method. This research aimed to obtain the resistivity value of Nichrome wire from two different methods. The methods were the Ohm law method and the Wheatstone bridge method. In Ohm law method, the wire length was subsequent varied. Then, the electric voltage value and an electric current were recorded. While in the Wheatstone bridge method, it was used circuit bridge. The value of the variable resistor was varied and the segment length metal plate was measured. The data were processed in order to obtain the Nichrome wire resistivity values by linear regression method. From Ohm law method and the Wheatstone bridge method were respectively obtained the value of Nichrome wire was ρ±Δρ=(2,875±0,005)x10-6 Ωm and ρ±Δρ=(5,00±0,25)x10-6 Ωm. The results of the two methods are match with the value of the standard of the Nichrome wire is ρ=1,0x10-6 Ωm. By using the two methods, it was expected that the students’ understanding of the electricity concept was increasingly widespread.

Abstract

To spur the development of the shipbuilding industry efficient and effective, then one will have to do is select the appropriate application of technology to existing conditions. Selection of the technology is closely related to the technical aspects in the field. National shipyards often get the order the construction of new ships with a capacity that exceeds the shipyard conditions. Based on limited means, but the implementation of the construction of ships should still be able to walk then attempted to carry out the connection of the hull below the water. With theadoption of block module, where assembly of the hull is divided into two parts, the module block bow and stern module block. Block modules separate hull is launched / lowered into the water, and then later made the connection in the water. As tools for splicing in the water system been caisson. Serves as a tool in connecting module block in the water then the caisson system must meet requirements such as: 1. The shape of the surface to be attached to the hull should have the same shape as the shape of the ship body. 2. Structure of the caisson to be strong enough. 3. The caissons must have stability and buoyancy are pretty good. In planning is the preparation before the second block of the module is launched into the waters, such as: 1. Determination of the number and dimensions of the hinge. 2. Determination of welding procedures. The process of implementing these connections include: 1. Control of the position of the module block such that the connections between the two. 2. Installation of the amplifier while. 2. Installation of the caisson continued process of welding the hull. 3.

Abstract

Several studies of multi-hulls ship showed that hull resistance could be predicted from position between the each hull. The design optimization of the hull form could be considered by minimizing resistance, which is generally the sum of the viscous resistance and the wave making resistance of the ship model. This paper presents an investigation of pentamaran hull form with chine hull form to the effects of outriggers position, asymmetry, and deadrise angles on the resistance characteristics. This research investigated the resistance characteristics by modeling pentamaran hull form using chine with symmetrical main hull and asymmetric outboard on the variation deadrise angles: 25o, 30o, 35o and Froude number 0,1 to 0,7. We examined the calm water resistance characteristics of six pentamaran models with chine-hull form by variation of deadrise angles using Ansys CFD. Increasing the deadrise angle of chine hull form contribute to the resistance due to the interaction of the wave systems produced by each demihull. Strong interaction effect on the resistance coefficient component was found for change in the hull length as well. Compared to the wigley hull form, the maximum drag reduction of the chine hull form was reduced by 18.05% in deadrise 250, 16.1% in deadrise 300, and 18.19% in deadrise 350. While the smallest value of total resistance coefficient was generated from chine 350 at R/L:1/14 and R/L:1/7. Optimum hull form for minimum resistance has been obtained, so it is interesting to continue with angle of entrance and stem angle of hull for further research.

Abstract

To support qualified IT operations, recently many companies have hired more than 1 (one) communication link as a redundancy and to improve High Availability or the availability of their network systems. One method to improve high availability of multi router networks (links) is to use Gateway Load Balance Protocol (GLBP) which is a protocol that works on OSI layer 3. Where the GLBP function is to divide the traffic load and as a failover function when one router / link is damaged. Gateway Load Balancing Protocol (GLBP) itself is born from the concept of load balancing, a concept that is useful for dividing / balancing loads or loads on multiple links to the same remote network. That way the network link will not be disturbed if there is damage caused by one of the routers.This thesis describes the concept of GLBP by using the weight method where network simulation tools use GNS3 software. The results obtained from the simulation with GLBP weight method sharing the router data load is determined by the weight value given to each router. Where Comparison of Weight Values given to the Router will determine the number of data packets transmitted to the router.
