Abstract

This research explores the potential of a plastic extruder machine as a solution to address plastic waste by utilizing high temperatures to melt and form plastic blocks. The machine aims to determine the optimal temperature for the production of plastic pellets. Despite initially producing plastic liquid, the machine is expected to effectively reduce plastic waste. The machine specifications involve an electric motor, gearbox, melting furnace, intake, melting spiral, output, pulley, and V-belt. Analysis of electric motor planning determines the required power. Gearbox planning involves gearbox ratio and required torque. Planning for pulleys and V-belts is conducted to transmit power from the motor to the machine's drive system. Planning for shafts and bearings was also carried out. The plastic extruder machine holds promise as a significant solution for plastic waste recycling. The manufacturing cost of the machine is found to be Rp17,349,350 and can be further reduced with a more optimal design. Recommendations for future research include enhancing detailed analysis and utilizing a richer set of references.

Abstract

AbstrakSistem suplai bahan bakar adalah cara untuk membawa bahan bakar ke ruang bakar, bisaberupa sistem bensin, diesel, atau bahan bakar lainnya.Untuk menciptakan pembakaran yangsempurna pada motor berbahan bakar bensin dimulai pada saat terjadinya loncatan bunga apipada spark plug atau busi kemudian membakar campuran bahan bakar dengan udara dalamkondisi campuran paling ideal yang telah diatur oleh ECU kemudian dikabutkan melalui throttlebody ke dalam ruang bakar sehingga dengan komposisi percampuran yang paling ideal akanmenghasilkan pembakaran yang sempurna. Pada saat pembakaran sempurna terjadi maka akansangat berpengaruh terhadap performa mesin yang semakin maksimal. Metode yang digunakanuntuk melakukan penelitian ini adalah metode eksperimental dengan pengujian daya dan torsi. Berdasarkan hasil analisa dan pembahasan pada bab sebelumnya dapat disimpulkan sebagaiberikut :Dengan penggantian variasi nilai AFR menjadi 13,5 : 1 daya maksimum mengalamipeningkatan sebesar 3,2 % dari ECU standar dan daya tersebut didapatkan pada putaran mesinyang sedikit lebih tinggi yaitu 8150 rpm yang sebelumnya didapatkan pada putaran mesin 8040rpm pada ECU standar.Dengan penggantian variasi nilai AFR menjadi 13,5 : 1 torsi maksimummengalami peningkatan sebesar 2,2% dari ECU standar dan torsi tersebut didapatkan padaputaran mesin lebih rendah yaitu 7920 rpm yang sebelumnya didapatkan pada putaran mesin8040 rpm pada ECU standar.Dengan merubah nilai AFR dapat meningkatkan daya dan torsisepeda motor.

Abstract

Abstract TIG welding is a welding technique for connecting metals using tungsten rod electrodes and using noble gas as a protective gas which is exhaled on the weld metal to protect against contamination with the surrounding atmosphere. Aluminum metal is a metal that has a high affinity for absorbing H2, N2 and O2 in the air at high temperatures, so it is necessary to have a high purity protective gas during the welding process, because N2 H2 and O2 will cause a decrease in the corrosion resistance of the material. To find out the effect of the TIG welding process on the mechanical properties and microstructure, a study was carried out to determine the mechanical properties, namely hardness, and bending properties, as well as the microstructure found in aluminum after the tungsten inert gas welding process was carried out using current. different. In this study the welding process used the Tungsten Innert Gas process by varying the welding current, namely 100 A, 130 A and with a welding time of 2.5 seconds, 4.5 seconds, . So that from the welding parameters used, it will be known the effect of the welding parameters Keywords : Welding Current, Alumnium Metal, TIG welding
