Abstract

Metal cutting process (cutting process) is to cut metal to get the shape and size and quality of the planned cutting surface. The metal cutting process is carried out with special tools, according to the type of cutting process. So the tools for one process cannot be used in another process, even for similar processes, the tools cannot be exchanged if the cutting plans are not the same. Lathe process is a machining process to produce cylindrical machine parts which are carried out using a Lathe. Its basic form can be defined as the machining process of the outer surface of cylindrical or flat lathe objects. Polyvinyl Chloride, commonly abbreviated as PVC, is the third-order thermoplastic polymer in terms of total usage in the world, after Polyethylene (PE) and Polypropylene (PP). Worldwide, more than 50% of PVC produced is used in construction. PVC is produced by polymerizing vinyl chloride monomers (CH2 = CHCl). Because 57% of its mass is chlorine, PVC is the polymer that uses the lowest petroleum feedstock among other polymers. This research follows up the selection of configuration of the lathe machining process using plastic work pieces. In this study, Maximat V13 lathe and PVC type plastic were used. The variation of machining processes are spindle rotation (320, 540, and 900 rpm), feeding speed (0.07, 0.14, and 0.28), the use of tool types (carbide and HSS) and cooling (without cooling, coolant, and oil). So, with this research, it is expected that the optimal parameters in determining the configuration of the lathe machining process on a PVC work piece to produce a good turning surface can be achieved

Abstract

The alternator on the motor is one component of the vehicle that can be used to improve its utilization. Modifications to the alternator on the vehicle are made to increase electric power. The working principle of an electric generator is in accordance with the law of faraday if a conductor is rotated in a magnetic field until it crosses the magnetic force line (GGM), it will cause an electric force line (GGL) in volts at the end of the conductor. In the alternator to be used, the lighting coil resistance is 0.24 - 0.36 Ω and the charging is 12.3 - 13.3 V at 1500 rpm. The research conducted was an experiment by comparing the alternator output voltage before it was modified with the alternator output that had been modified. Modification of the alternator is done by the method of load variation and replacement of the diameter of the coil along with the number of turns on the alternator. Measurement of alternator before and after modification shows results that are directly proportional to the output of the alternator at 1,000 rpm - 8,000 rpm. The results of three tests can be concluded that the modification of the alternator has increased from 6.42 A for the standard alternator to 13.7 A for the modification alternator.

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).

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.

Abstract

This paper discusses the granulator machine testing process. This test aims to determine the process of occurrence of granular. Granular pellets are one form of feed pellets, granular (rounded) and light in weight. Granular pellets are not easy to sink but are easily broken down in water. This type of pellet is made without going through the process of pressing, so that it can produce feed grains that are light weighted, not easily submerged but easily decomposed in water. The goal is to determine the optimal state of the granulator machine with three angular tilt positions, it can perform maintenance on the granulator machine. The granulator machine testing process is carried out by means of the plate angle measurement process, the water mixture measurement process, the plate speed measurement process. Material used for the testing process uses flour and water. While the tools used in the granulator machine testing process are spray, 14 key, sieve, and container. After testing at 3 angles at an angle of 25o, angle of 30o and angle of 35o the authors conclude that this machine can produce small granules at a slope of 250 with an engine speed of 17 rpm and average weight of granular which is produced 236 grams. While the results of hourly 3 kg / hour.

Abstract

Penggunaan serat alam sebagai reinforcement pada material komposit semakin diminati pada satu dasawarsa terakhir ini. Hal ini disebabkan karena serat alam lebih ramah lingkungan ,memiliki densitas yang rendah, kompatibel dengan alam, dan harganya yang relatif murah. Salah satu penggunaan serat alam pada material komposit adalah serat kulit pohon waru (hibiscus tiliaceus). Kekuatan komposit serat kulit pohon waru (hibiscus tiliaceus) tidak hanya dipengaruhi oleh reinforcement dan komposisi antara serat-resin, akan tetapi juga dipengaruhi oleh jenis resin sintetis yang digunakan.Serbuk Alumina (Al2O3) adalah salah satu contoh material filler yang sering digunakan pada material komposit.Tujuan dari penelitian ini adalah mengetahui pengaruh penambahan serbuk alumina (Al2O3) terhadap energi impact yang diserap ,harga impact dan patahan komposit kulit pohon waru. Metode yang digunakan dalam penelitian ini adalah metode eksperimental.Dalam penelitian ini peneliti menginginkan pemanfaatan serat kulit pohon waru sebagai bahan alternatif penguat komposit.

Abstract

The increase in NOx levels produced by CNG-fueled engines occurs when the fuel switches from gasoline to gas fuel (CNG). The author changed the otto 4 stroke gasoline engine, into a CNG-fueled motorbike and provided additional cooling in the form of a burst of air to the cylinder block. Changes in engine block temperature are detected using a temperature sensor placed on the engine oil. Bursts of air cooling result in temperature changes in engine oil. Changes in engine oil temperature are accompanied by changes in the resulting NOx emissions. This study shows that with a decrease in engine oil temperature in the combustion engine, NOx emission levels also decrease. From the research results it can be ignored that by providing additional air bursts will be able to reduce NOx emissions by up to 18%
