In the CNC milling machining process, the surface roughness of the workpiece is one of the most important things. By using the box method, the design method is to find parameters that affect the surface roughness of the workpiece. This study aims to determine the effect of feeding speed, feed depth and cooling discharge on the level of surface roughness. And find out which parameters produce the lowest surface roughness value in the CNC milling machining process. From the results of statistical analysis with a significant level in the amount of α = 5% (0.05) obtained feed speed parameters with a value of P> F = 1.79% and depth of infeed with a value P> F = 0.03% proved to have a significant effect on surface roughness, on the parameters cooling discharge proved not to have a substantial impact in surface roughness with a value of P> F = 5.82%. While the optimum combination for the lowest level of surface roughness can be obtained by a combination of 0.18 mm feed depth parameters, 180 mm / minute feeding speed and 10 ml / second cooling discharge with the lowest surface roughness value of 1.027 µm. Keywords: surface roughness, Behnken design box, CNC milling

Airplane stability is required when the aircraft has a left engine in operative (LEI). LEI is the condition of the left engine part of the aircraft not functioning when flying or taking off. The LEI can be anticipated by using a rudder as support. The purpose of this study was to determine the aerodynamic characteristics of the rudder. The research methodology is by rudder aerodynamic analysis using Datcom digital software simulation. The simulation input data consists of: coefficient of yowing deflection of debt (CNDR) = -0.0022889 / deg, and Vertical Volume (Vv) = 0.0830. Previous tests used VV = 0.79 and then VV = 0.83. The results showed that the number Vv = 0.83 was more stable compared to Vv = 0.79. The research conclusions are that if the plane experiences an LEI, then the stability of the rudder is conditioned as follows: Vv = 0.083, CNDR = -0.0022889 / degree, lift coefficient CL = 1.8837 and angle of attack (α) = 8.3277. Keywords: Left engine in operative, vertical volume, Digital Datcom, Angle of attack

Increasing energy consumption causes problems of natural resources, especially fossil energy. Micro Power Generator (MPG) is a technological breakthrough that can help save fossil energy. There are two main parts to MPG, namely micro or meso scale combustor and a converter module. For optimizing meso scale combustor, the best fuel is needed between LPG and Butane. This research was conducted to determine the combustion characteristics of meso combustor at the equivalent variation ratio of 1.15 and 1.20 at the reactant rate of 30 cm / s. The study was conducted on ignition of the combustor meso scale space with dimensions of 30 ml in length and 3.5 ml in diameter, with variations in the supply of air in fixed fuel supply. Combustion characteristics include temperature and color of fire. Butane flame temperature in the variety of equivalent ratio is higher than that of LPG fire. The fire color produced by Butana is dark blue and light blue LPG. This shows that the combustion of butane in meso combustor is better than LPG. Keyword: Butane, LPG, combustor meso scale, fire color, flame temperature

Exhaust Pipe Preheated Fuel System (EP2FS) is a fuel heating system that utilizes wasted heat from the exhaust. Heating the fuel aims to increase the homogeneity of the mixture of fuel and air to improve the combustion process in the engine. Making EP2FS requires careful design and calculation because the temperature of the fuel must not exceed 60 oC so as not to evaporate. The design and estimation use the helical heat exchanger (theory of heat transfer). The system that is ready will be applied in motorized vehicles to be tested for combustion efficiency and performance. Keywords: Fuel Preheating, Engine Performance, Helical Heat Exchanger

As a plane that is still in flight testing period then the N219 aircraft needs to be assessed for evaluation purposes. Focus in this study is on field of performance. This field is studied to determine the performance of N219 aircraft especially in the cruise phase. This study was conducted with the aim to determine the effect of variations in the selection of flying alititudes on the achievement of maximum endurance flying. The calculation method is done by using Pr-V graph. This method is used to determine the maximum endurance through the minimum power required curve. The result show that the increase in flying height cause the decrease of air density. This happens because the pressure and temperature of the air also decreases with increasing height. In addition, the increase in flying altitude also affects the fuel flow. Fuel flow decrease with increasing altitude. Conversely, the maximum endurance increases with the increase in altitude. This happens because the endurance is derived from the division of the fuel flow weight, so the endurance is inversely proportional to the fuel flow. The lowest maximum endurance value occurs at sea level is 6,48 jam, and the highest maximum endurance value occurs at 10.000 ft is 8,65 jam. Keywords: Endurance, cruise, altitude

Al-Si alloy is one of the alloys that are widely used in the industry because it has a good cast and good strength. To increase its mechanical strength Cu alloy can be added which can be covered. Al-10Si-Cu alloy is one of the alloys commonly used in industry, especially the automotive industry because it has excellent mechanical strength. This research is focused on looking at the effect of artificial aging on T6 heat treatment to increase the hardness of Al-10Si-3Cu alloy results from casting. Dilution behavior was carried out at a temperature of 520 oC for 2 hours then quenched in water and then performed artificial aging carried out at 130oC with aging time varying from 5 minutes to 120 hours. Material characterization carried out hardness testing, tensile test, microstructure observation with an optical microscope. The highest hardness was obtained with an 80 hour holding time of 86.05 BHN where CuAl2 precipitates underwent optimum conditions. The most upper tensile strength was collected at 80 hours holding time, namely 335.063 MPa with strain value 1.133%. A low strain value indicates that this condition has begun to overgrow, so embryo has started to occur.

Flight performance is determined by the lift coefficient (CL) and drag coefficient (CD). CL and CD values are influenced by the geometric shapes of aircraft wings. Air flow through the side of the aircraft causes wingtip vortices. Wingtip vortices add induced drag to the arms of the aircraft, creating reduced aircraft aerodynamic performance. Induced drag is a drag that results from the whirlwind of air flow due to differences in pressure on the surface of an aircraft wing. Previous studies obtained data that the use of winglets on sides with 45 o bending angle can increase the CL / CD ratio by 20.73% when compared to winglets. Winglet bend angle affects fluid flow and CL / CD ratio. The purpose of the study was to analyze the winglet bend angle of the aircraft wing aerodynamic performance. The winglet bending angle variations used were 0o, 30o, 60o, and 91.4o. Analysis of the bending angle on the winglet was done with VLAERO + software. The winglet bend angle is simulated with aircraft attack angles including - 15o, -10o, -5 o, 0o, 5o, 10o, 15o and 20o. The results showed that data for bending edge 91.4o produced CL / CD of 97.452, while wings without winglets only had CL / CD values of 80.701 at 0o attack angle. Winglets with 0o buckling angles reduce CD max at a 20o attack angle by 7.03%. The conclusion of the study informs that the addition of winglets can improve the aerodynamic performance of aircraft wings. Keywords: winglet, VLAERO +, cant angle, lift coefficient, drag coefficient.
