Abstract

In general, plastics have low density, are insulating to electricity, have varying mechanical strength, limited temperature resistance, and varying chemical resistance so that they are widely used because of their advantages. Efforts to manage plastic waste practically and effectively to reduce the widespread pollution. The purpose of this study was to find out the effect of the use of condenser cooling water on the results of the distillation of plastic waste capacity of 3 Kg. Testing was carried out in two ways: measuring the relationship of the time and heat of the kettle, the relationship of time and heat of the condenser. The results showed that the longer time achieved will be the greater the increase in the temperature of the kettle obtained that is 650C to 720C means a change (720C - 650C = 70C), and the longer time achieved will be less heat obtained ie heat value of 2805.688125 and hour later decreased by 2622.88125. In conclusion, the longer the time reached at the time of energy administration in the kettle and the provision of energy to the condenser, the greater the increase in the temperature of the kettle.

Abstract

Laser technology is now so rapidly and is used in almost all fields, such as in manufacturing, medical, arts, trade transactions and printing. Although there are various types of lasers on the market, the C02 laser is the most common in manufacturing. This is due to its relatively large power so that its use is more flexible and can be used for cutting thin sheet materials as well as rather thick materials. Laser cutting has various advantages over other manufacturing technologies because it can receive data directly from the computer, so that cutting automation can run in the industrial world. The use of CNC (Computer Numerical Control) machines in laser cutting systems is very necessary, because we can cut a material with the design shape we want and with good cutting quality. The method used is experimental by designing and manufacturing and testing a CO2 laser cutting CNC machine. Testing is done by finding the best feedrate and knowing the level of accuracy of the cutting results on different types of cutting grooves. From the results of the study it can be concluded that the best feedrate is 50 mm/min, and also the level of accuracy with different groove cutting shapes affects the level of cutting accuracy, the lowest accuracy coefficient is 0.73 mm.

Abstract

The use of synthetic refrigerant R22 has been banned by the government which can cause damage to the ozone layer causing global warming effects. temperature (ΔT°C) of the evaporator during the test time at the time of the study. The method used in this research is to vary the refrigerant R 22 and Musicool 22 with a pressure variation of 60,70,80 Psi, the size of the room studied is 3x4x2,5 m and Split AC Changhong, LG, and Panasonic with 1 PK power. Research results it can be seen that each brand of Split AC has a different effect of electricity consumption, the lowest and highest electricity consumption at a pressure of 60 and 80 Psi. Musicool 22 refrigerant is more energy efficient than R22. It can be seen that each brand of Split AC has the effect of the temperature difference (ΔT°C) of the evaporator, which differs the highest at a pressure of 60 and 80 Psi. Musicool 22 refrigerant is more suitable for LG and Changhong brands.

Abstract

EDF is an electric propulsion consists of a duct, fan, and electric motor with the motor power source coming from a battery which creates compression air for thrust. The design and configuration of an EDF is not complicated as a jet engine, but it could generate high thrust for highspeed flying like highspeed UAV needs. The preliminary design of an EDF yields a design and performance estimation. The design needs validation by experimental tests for real performance data. The test needs test tools and EDF itself. The aim of this research is experimental testing of an EDF for real performance data as validation of the existing design. The performance test is done by EDF test bed hence the manufacturing process of EDF is done by 3D printing. Test results show differences in performance of EDF with estimation results by analytical approach. The thrust of EDF from the experimental test is lower than the estimation calculation from the preliminary design, so the EDF does not fill the design criteria yet and needs refinement design.

Abstract

The need for motorized vehicles in Indonesia has increased, following the conditions of the Indonesian people who have high mobility. Currently, the Government of Indonesia is trying to control the use of fuel oil, so a solution is needed to modify the octane value of the fuel used while still paying attention to performance and exhaust emissions from vehicles. The addition of Eco Racing to pertalite can increase the octane value, thus affecting fuel consumption. This study aims to determine the effect of Eco Racing variations on performance, fuel consumption, and exhaust emissions on a GL Max motorcycle. This study uses an experimental method with testing using a dynamometer and a gas analyzer. The results showed that the variation of Eco Racing had an effect on performance, fuel consumption, and exhaust emissions on the Gl Max motorcycle with the best mixture being 2 Eco Racing tablets. Performance has increased with the best torque produced being 9.15 Nm and the best power produced is 9.8 HP. Fuel consumption is decreasing until it reaches a value of 2.1 kg/kWh, making it more fuel efficient. Exhaust emissions are more environmentally friendly where CO becomes 5.91%, HC becomes 6011 ppm, and CO2 becomes 2.63%, while O2 increases to 11.51%. The condition of the vehicle affects performance so that the increase in torque and power can only be maintained up to 8000 rpm and the Eco Racing mixture is not able to reduce Hydrocarbon emissions to below the Threshold Value. Where in this study, hydrocarbons were only able to be reduced to 6011 ppm, while the threshold value that had been set was 2400 ppm.

Abstract

The strength of welded joints is influenced by a wide variety of factors. One of them is due to structural changes as a result of the heating process. In order for the connection between the two metal parts to have good quality, it is necessary to have a proper welding and the connection and the shape of the weld bevel are in accordance with the use of the results of the weld. Parameters in Shielded Metal Arc Welding (SMAW) welding include current strength, voltage, electrical polarity, and the angle of the joint used. These parameters make the basis for the right selection in order to get a good quality or connection quality. The purpose of this study was to determine the effect of bevel variations on the tensile strength test of the SMAW welding process connection on medium carbon steel material. The welding process is carried out using RB 26 type electrodes using a current of 100 A at 1 G welding position, welding is carried out on the material using V, I and double V bevel with 1 specimen per bevel. Based on the research that has been done, it can be concluded that the type of joint bevel has an important influence on the results of the weld. From the variation of the bevel that has the highest tensile strength value, it is V bevel rather than double V bevel and 1 bevel. Due to the variation of V bevel has a small distortion angle compared to double V bevel and I bevel. Optimal electric welding results depend on the welding process technique.
