Abstract

One of the alternative fuel mixture that can be used by the gasoline motor is Brown's Gas. The gas is produced from the electrolysis solution of baking soda inside the elektrolizer. Percentage of baking soda solution is 99.45% destilled water and 0.55% baking soda.This research used a Suzuki Smash 110 cc motorcycle. Testing performed with engine speed of 1500, 2000, 2500 rpm. The testing time is 2, 3, 5, 8, and 10 minutes. Observation and calculation showed that the average rate of fuel consumption respectively are 125,7, 176,5, and 243,0 gr/h for gasoline and are 96.4, 121,9, 171,6 gr/h for motor combination brown gas and gasoline. From the above results it’s obtained that the efficient fuel consumption is 171,6 gr/h that is with engine speed 2500 rpm.Linear regression model is y = -5.919 x + 204.7 (R ² = 0.858), while quadratic regression model is y = -2.226 x ² + 20.72 x + 145.5 (R ² = 0.541). The quadratic regression fit better to the data for the coefficient of determination closer to 1.Keywords: Gasoline Motorcycle, Suzuki Smash 110 cc, Brown Gas

Abstract

The use of water pumps DAB type DB-125 as the impulse turbine functions for Micro Hydro Power Plant Lisrik (PLTMH) is the topic in this research. Water pump is used to suck water and deliver it to a certain height. In this application the water pumps used as turbines where water from a certain height will rotate the impeller pump and produces electricity. The testing is done in the laboratory of mechanical engineering of University of Sam Ratulangi. Turbine is driven by three pumps which are assembled in series and parallel, to get different head and flow (Q). Water flow and load on dinamometer ( ) have been set at the lowest rotation of the load on turbine. For the initial set of water flow Q = 33,5 litres/minute. The results showed that the different H and Q from curve turbine rounds, maximum power is at Q = 40 litres/minute, H = 33,5 m, and n = 910 rpm

Abstract

ABSTRACTUtilization of water pump Shimizu Type PS-128 Bit which functioned as a water turbine for Micro Hydro Power Plant (MHPP) is an effort in the search for alternative energy in a simple and easy in term of manufacturing and assembling. Principally, the water pump is used to suck the water from a lower surface and raise it to a certain height. The basic of working of a pump is the opposite of a water turbine, and therefore can function as reaction water turbine, in which water from a certain height rotate the pump impeller.Testing the water pump Shimizu Type PS-128 Bit as a water turbine is carried out in the Laboratory of Mechanical Engineering University of Sam Ratulangi. The “reaction turbine” is driven by four water pumps which connected in series and parallel. It aims to get different heights (head) and flow rate (Q).Flow rate and the load on the dynamometer (W1) has been determined, as the lowest round “reaction turbine” that is charged with the force (N) certain turbine cannot rotate. So that initial water discharge is determined by Q = 31 liters/minute. Based on the research that has been done that the power generated depends on the rotation, H and Q. The maximum power generated Pm = 12 watt is at Q = 37 liters/minute, H = 18 m, and n = 1080 rpm.Keywords: Pump, Reaction Turbine, Head, Flow rate.

Abstract

ABSTRACT The purpose of this research is to analyze the ratio of the snarled thickness on a lathe machine. The problem of this research is how the influence of the snarled thickness ratio on turning process with varying cutting speed and different cutting depth. Some tests on the turning process on a number of work pieces with same material type and different cutting condition is cerried out. The result shown that higher cutting speed make snarled thickness ratio weaken, while the larger cutting depth make snarled thickness ratio increased. With a 95% confidence level variation of cutting speed will influence to snarled thickness ratio on turning process either 0.25 mm of cutting depth or 1.00 mm of cutting depth Keywords: Snarled thickness ratio, cutting speed, cutting depth, turning process

Abstract

In this study whether the effect of cuts without using coolant differ significantly by cutting use liquid cooling to the power cut. To get the effect these cuts do testing on a lathe with a cutting speed varied. The results of this study, based on cutting anlisis detected by the fifth variation of the cutting speed will affect the power cut. With the greater the cutting speed will increase cutting power, good for lathing process with and without coolant. The process of turning the cooling liquid tends to be greater influence on cutting power compared to the lathing process without coolant. Based anlisis regression and correlation with level of 5% error hypothesis test two directions is known that in the process of turning cutting speed without coolant does not affect the power cut amounted to 73.48%. While in the process of turning to liquid cooling effect on the cut of 97.56%. Keywords: Cut Speed, Coolant, turning, Power Cut

Abstract

The lathe machine is a machine tool that rotates a workpiece to perform cutting. Lathe it self constitutes a procces that cuts rotating workpiece used chisel that moves parallel with rotating axis. The cutting process will generate heat. The lathe machines is equipped with liquid direct contact cooling system to cooling the chisel and the workpiece. This research, observed the effect of cooling liquid flow rates toward the heat, generates by cutting procces of a cylindrical workpiece.The are two aims of this research. The first aim, is to calculate the gerenates by the cutting process of a cylindrical workpiece. The second aim, is to know the number of cooling liquid flow rates that is good to cooling the chisel and the workpiece. Experiment were done by three variations of cooling flow rates, that is regulated by the open angle of cooling liquid’s ball valve. There are three open angle variations that are 300, 600, 900.From the experiments, the used of the cooling liquid is able to cooling down the high temperature due to cutting process. At 900 open angle of cooling liquid’s ball valve showed a better effects of cooling process. However, the decreases of temperature done by 300 and 600 open angle position of cooling liquid’s ball valve are not significant. Keyword: the effect of cooling liquid flow rates toward the heat, generates by cutting procces of a cylindrical workpiece

Abstract

This research is a test method carried out on the IXION BT 25 bench drill machine which has been developed using a cooling system. After the drill process is carried out on the test object, the drill chisel is measured for tool wear using a digital microscope measuring instrument.From the results of the measurement of drill chisel wear, it is obtained that a drill diameter of 8 mm results a tool wear of 0.3608 microns, a drill diameter of 12 mm brings a tool wear of 0.0540 microns. Whereas, a drill diameter of 17 mm results a tool wear of 0.1030 microns and a drill diameter of 23 mm brings a tool wear of 0.0108 microns. From these results, tool wear that occurs in the drilling process using the coolant developed on the IXION BT 25 bench drill machine will decrease with the larger the drill diameter. From the correlation analysis, it is found th at the relationship between drill diameter and tool wear tends to be very close with a correlation coefficient of 0.78467 and shows that the drill diameter and tool wear have opposite directions. Keywords: Chisel Wear, Drill Bit Diameter, Bench Drill Machine IXION
