Abstract. Indonesia is a maritime country where 2/3 of its territory is ocean. Therefore, many ships are needed for transportation from one island to the nother within NKRI region. The AA5083H116 materials are widely used in maritime transportation vehicle due to its low density and high weldability. The research propose is to characterize the influence of welding speed of Metal Inert Gas (MIG) of AA5083H116 using ER5356 electrode on the welded joint properties. The AA5083H116 materials of 3 mm x 1200 mm x 2400 mm dimension were cut into welding specimens of 3 mm x 75 mm x 300 mm size. Any pair of specimens was welded using electrode of 0.8 mm diameter. The welding parameters being used are 19 volts of electrical voltage, 120 amperes of electrical current, and 8, 10, 12 mm/s of welding speeds. The characterization were carried out on angle distortion that measured using dial indicator on a milling machine table, X-ray radiography test, as well as physical and mechanical properties tests i.e. microstructure, Vickers micro hardness, tensile and bending strength. The research results show that the smallest distortion angle was found at welding speed of 12 mm/s, all of the welding results satisfy the distortion angle of < 5o, and the radiographic results satisfy the DEPNAKER RI regulation standard. The microstructure exhibits Al2Mg3 precipitation, Vickers hardness distributions, while the highest tensile and bending strength were obtained at welding speed of 10 mm/s.

Abstract: The study was executed to get a quick calculation method for the design of equipment heat exchanger type shell and tube with a program shell and tube heat exchanger design. The purpose of this study was to obtain the results of the validation program shell and tube heat exchanger design of a condenser with power 4368.75 kW and the results of the evaluation program shell and tube heat exchanger design on the thermal design condensers nuclear power plant AP1000 PWR type. Input data into the program is done by inserting the parameters temperature, flow rate, physical properties and geometrical dimensions of the available designs of heat exchanger equipment specifications. Parameter for comparison of data can be obtained from the results of other calculations or experimental data. The results of comparison of the validation program shell and tube heat exchanger with condenser design calculations showed the highest difference found on Utube parameter equal to 1.3% lower than the design condition. This occurs because of differences in calculation between the program designed. The result evaluation of program shell and tube heat exchanger design toward the thermal design condensers nuclear power plant PWR type AP1000 obtained unknown parameters from the technical specifications.

Natural materials are environmentally friendly materials that can be made as components of matrix and reinforcement. Wood is part of the stem or branches and twigs of hardened plant due to lignification. Bamboo is a type of grass plants belonging to the order Graminae, familia Bambuseae, rooted fibers, the trunk-shaped cylinder with a diameter that varies from base to tip, hollow, hard. The composite is a composite of two or more materials that are integrated macroscopically and form a new properties. The composite type used in the laminate composite consists of two different layers of material and combined together, using adhesive, the manufacturing process using the hand lay up method. Matrix used balsa and mahoni wood, for reinforcement used type of bamboo apus molded basket woven. Bending test, using ASTM D7264 / D7264M-07 standard. The results of the experiment by testing each test, using 3 test specimens, then taken the average value. For balsa wood matrix, with plain woven reinforcement, buckling strength with value 35.60 ± 2.30 MPa, for balsa wood matrix, with basket woven reinforcement, buckling strength with value 32.64 ± 4.20 MPa. For mahoni matrix, with plain woven reinforcement, buckling strength of 55.15 ± 4.89 MPa, for mahoni matrix, with basket woven reinforcement, buckling strength of 77.15 ± 4.88 MPa. From these data shows that by using mahoni matrix the buckling strength is greater than using balsa wood matrix, either using plain or basket woven.

AA7075-T6 aluminum alloy is a material that widely used in the aircraft industry because aluminum as a lightweight metal, good machinability, good corrosion resistance and good castability and non-magnetic metals. Aluminum also has high tenacity, is easy to form and is easy to connect. Aluminum has good resistance to corrosion, however aluminum has effect to corrosion if it is on corrosive environment including AA7075-T6 aluminum alloy which used in the aircraft industry. Inhibitor is used to control a corrosion. The aims of these researchs were to investigate the effect of inhibitors on corrosion rates and the rate of fatigue crack corrosion propagation on AA7075-T6 aluminum alloys. This research is used Na2CrO4 inhibitors with variety of concentrations of 0.1%, 0.3%, 0.5% and 0.7% added to 3.5% NaCl solution. Corrosion rate test is used a method of potential dynamic polarization. Corrosion fatigue testing is carried out with constant amplitude at a frequency of 10 Hz and a voltage ratio (R) 0.1. Specimens were used cracked specimen centers (CCT) on orientation in the direction of rolling. The supporting data of the research were the mechanical properties of the material included optical microstructure observation, tensile testing and hardness testing. The results have shown that the optimal concentration of Na2CrO4 inhibitors was achieved at 0.5% which was characterized by a decreasing in corrosion rate and slower corrosion rate of fatigue cracking.

Abstract: Automation is a technology that can be used to implement an instructional process or an automatic procedure. In this framework that has been using an instructional program that combined with a control system to process an instruction or commands. This processing module is a part of the automation which checking a process simulation of hollow and not hollow objects, then a PLC is use to control the process as designed be needed to control all of the working processing modules systems works. working system, a programming language that easily to be understood is needed such as functional block diagram (FBD) is use to program a plc system which functional block diagram (FBD) is a method that can describe a function between input and output variable, in FBD there is a Sequential Function Chart method (SFC ) which control the program sequential activity. So this research discusses the control of processing module which based on FBD programming language by using the SFC method.

Fueled by a rise in food needs as beef and oil into basic commodities has been consumed by thepublic, has lead the increasing of waste the cows and coconut shell. The main ingredient used in thisresearch is a waste product from cow bones and from the remains of the coconut shells from which no orhousehold wastes, that can be processed into charcoal. The purpose of this research which is to enhanceeconomic value of waste from cow bones and coconut shells using combustion pyrolysis system beingcharred (fixed carbon) to produce good quality charcoal, to find out the extent of the temperature used andthe composition of charcoal. The process used in this research is pack carburizing with cow bones andcoconut shell as the media at the temperature 950oC, time detention three hours with variations compositioncharcoal. It can be concluded that charcoal bone across his cattle and charcoal coconut can be used as asource of carbon that might improve the force and hardness in the material carbon steel low (low carbonsteel). The process of pack carburizing can increase the value of % C, against low carbon steel material.
