Abstract

Motorbikes that are very much operated every day need fuel oil which is a fossil fuel that has been depleted and cannot be renewed. With the current conditions, it is necessary to control fuel consumption on a motorcycle. Setting the intake lobe lift, the exhaust lobe lift and valve gap have a positive impact on fuel consumption. There has been a lot of research about setting the intake lobe lift, the exhaust lobe lift and valve gap. The number of conventional motorcycle vehicles that are still operating requires special arrangements and deeper studies to be able to be economical in fuel consumption. The objectives of this study are: (1) to identify the factors that cause high fuel consumption. The research method uses the experimental method. By using pertamax. . The results showed that: 1) modification 2 uses the longest fuel consumption, and 2) there are effects of variations in the intake lobe lift and exhaust lobe lift on fuel consumption, 3) there is an effect of adjusting valve gap variations on fuel consumption, 4) there are the effect of variations in the intake lobe lift and exhaust lobe lift and adjustment of valve gap variations on fuel consumption.

Abstract

The amount of chicken production and consumption produces large amounts of waste as well. The amount of available chicken feather waste is not used properly so it needs an alternative to utilize chicken feather waste to be something more useful and innovative, one of which is to waste broiler chicken feathers. The main objective of this study was to obtain a variety of composite boards made from resin with broiler chicken feather filler instead of tile tiles. The making of composite specimens from polyester resin with yucalac 157 BQTN-EX type by adding different prepared chicken feather fillers in order to find out the best flexural and compressive strength from one variation of chicken feather filler arrangement. Composite specimens were made with the standard ASTM-D size 7264. Analysis of the test data using the TWO-WAY ANOVA approach ¬ to determine the effect of the transmission of chicken feather filler on flexural strength and press.The results of the flexural test obtained the lowest yield strength with a composition in the direction of 0 ° worth 11.3 MPa and the highest yield strength with a 45 ° alternating composition worth 54.5 MPa. For the compressive test results obtained the lowest compressive strength with a random composition of 23.9 MPa and the highest compressive strength of 34.5 Mpa. For the bending test and press on the tiles, the value of 1.1 MPa and 0.29 MPa means that the composite value is higher than the value of tile tiles.

Abstract

This project aims to change the conventional ignition mechanism to beautomatic by utilizing the microcontroller-based technology. The driver startsthe engine using a smartphone microphone and bluetooth smartphone thentransmitted to the HC-06 bluetooth module that connected to the Arduino uno tomove the 5v relay module wirelessly The driver can start the engine by openingthe Arduino bluetooth voice controller application on the smartphone and thencommands the sound then sends a signal to the Arduino Uno to start the enginewithout using a conventional ignition key. Wireless communication between thesmartphone and the actuator on a motorized vehicle can function properly if usedwith a range of distances from 1 meter - 50 meters with the condition that thesensor has been applied to the vehicle

Abstract

Safety and comfort are the valuable factor for the driver. One of the safety factor refers to the steering accuracy. Steering wheel hardness must be soft when turning but remain stable in straight track. The comfort factor refers to the bouncing effect when the car passing in rough track. Those two factors is depend on the shock absorber components. This study aims to know the optimum gas pressure and spring pressure to obtain the maximum vibration reduction. This study use the experimental methods use the 6 bar, 8 bar, and 10 bar of absorber pressure. The spring pressure used in this study is 20 , 25 dan 30 (Kg/cm2). The data obtained were analyzed with MINITAB software. From the results of research on Optimizing Shock Absorber Pressure and Coil Spring Pressure Against Car Vibrations can be concluded as follows: 1. There is an influence of absorber pressure and spring pressure on the suspension on the amount of vehicle vibration. The optimum absorber pressure is 10 (bar). 2. The optimum coil spring pressure at 24 (kg / cm2).

Abstract

Plug welding is one of the welding methods of joining material with filling techniques using filler metal. This study aims to determine the effect of variations in electrical current and depth of artificial penetration of Ø8 mm holes on the failure mode and tensile load bearing capacity of dissimilar metal plug welding connections between SS 304 series stainless steels and SS 400 series carbon steels. used are 200, 215 and 230 A while the variation in depth of artificial penetration with diameter of Ø8 mm is 0, 1 and 2 mm. The results of this study indicate that the variation of the welding current without any artificial penetration (0 mm) results in an interfacial failure failure mode. While the existence of artificial penetration with a depth of 1-2 mm produces pull out failure mode. The results of the shear tensile test showed that the highest welding strength was obtained at a variation of 230 A with a hole depth of 1 mm at an average of 12.6 kN while in the hole depth parameters 0 and 2 mm the weld strength values ​​were obtained at a mean of 5.6 and 7.8 kN.

This research used experimental method with variables used in this research is mixture of pure pertalite (P), mixture of pertalite - methanol 90% - 10% (PM1), mixture of pertalite - methanol 80% - 20% (PM2), mixture of pertalite - methanol 70% - 30% (PM3), mixed pertalite - methanol 60% - 40% (PM4), 50% - 50% (PM5) pertalite - methanol mixtures, pertalite - methanol 40% - 60% (PM6). Variable related in this research is power, torque and working temperature of the engine. The results of this study indicate that the addition of methanol with pertalite fuel tends to produce lower power and torque, while the temperature of the radiator and exhaust system shows that the use of methanol mixture with pertalite fuel can significantly increase the engine temperature of the vehicle.
