Abstract

The process welding which in principle is connecting two or more components, more rightly aimed toassemble ( assembly ) several components into one form of machine. The purpose of this research is to findthe mechanical force low carbon steel and high carbon steel. Material of this research is low carbon steelplate thick of 10 mm and high carbon steel of a spring thick 10 mm. the process welding use electrodesE6013 and E7016 by the angle v . Test in do is testing pull and testing hardness brinell .Where testing pull ,tensile strength on the highest low carbon steel found in specimens 2 namely 44,92 kg/mm2 .While in testingpul high carbon steel tensile strength is highest in specimens column material that is 91,35 kg /mm2. ForBrinell Hardness Test, the highest hardness HAZ to low carbon steel is on a point of 1 and 3 namely 104,53kg/ mm2. While highest hardness HAZ to high carbon steel is at that point 1 namely 201,03 kg / mm2.Keywords: welding, tensile strength and hardness

Abstract

The purpose of this study was to determine the fuel consumption of the motorcycle Yamaha Vega ZR assembled in 2009 by using the intake manifold with the basic material of the fiber composites. This studyused an experimental method. The sample is a Yamaha Vega ZR motorcycle is assembled in 2009 to number Engines: 5D9-191066. Data collected through the experimental method. The consumption of fuel measuredin static conditions with a measuring glass. Testing is done by measuring the time required by the machine to spend in a given volume of fuel at the 1500 rpm ,2500 rpm and 4000 rpm. Results showed that the differencein the time required to spend 10 ml of fuel between the use of intake manifold standard with intake manifold fiber composite fibers in the round 1500 rpm is 0.11 minute, the lap 2500 rpm is 0.08 minute and at enginespeed of 4000 rpm is 0.04 minute. The difference in the average time required to spend 10 ml of fuel is 0.07 minute at 1500 rpm until the engine rotation 4000 rpm. Thus, fuel consumption decreases when using theintake manifold with the basic material of the palm fiber composite intake manifold using standard.Keywords: palm fiber composites, intake manifold and fuel consumption.

Abstract

The rapid development of a variety of disciplines to encourage the advance of civilization of human life. Use elbow in the system design perpipan causing a loss of pressure in the flow. It because by a change in direction of fluid flow through the channel. The pressure drop (pressure drop) to flow past the elbow is greater compared with a straight pipe of the same length. The size of the drop in pressure (pressure drop) to flow through the elbow is affected by the magnitude of the radius of curvature and angle of the bend of the elbow itself that caused the separation (separation loss) and secondary school (secondary flow) on the elbow 900. From the results of this study concluded that the pressure distribution at Re 8.1737 x104 is smaller than Re 10, 1467 x104, while pressure on Losses Re 8.1737 x104 is smaller than Re 10.1467 x104. Keywords: Distribution analysis, air pressure, and elbow 900.
