Abstract

AbstrakSalah satu proses yang penting dalam pembuatan bahan berbentuk pellet adalah proses kompaksi. Penelitian ini mempelajari struktur morfologi bahan semikonduktor ZnO yang dikompaksi dengan tekanan berbeda. Bahan awal adalah ZnO murni yang digiling dengan agate mortar, disaring dan dipadatkan dengan tekanan 10 bar, 20 bar dan 30 bar sehingga berbentuk pelet. Ukuran pelet adalah Ø 13 x 2 mm. Selanjutnya, pelet ini disinter pada temperatur 1300oC dan kemudian diuji dengan menggunakan scanning microscope electron (SEM). Hasil pengujian menunjukkan bahwa struktur morfologi partikel material semikonduktor ZnO yang dikompaksi dengan tekanan 30 bar memiliki struktur morfologi yang tidak beraturan dan tidak terlihat batas butirnya. Ketika material tersebut dikompaksi,  ruang antar butir menjadi sangat kecil dan tidak mampu menampung pembesaran partikel akibat proses sintering sehingga kelihatan menyatu dan menjadi keras. Oleh karena itu, semakin besar tekanan kompaksi maka struktur morfologi dari suatu partikel menjadi lebih padat dan menyatu. Namun demikian, besarnya tekanan kompaksi harus diperhatikan dengan mempertimbangkan kemampuan gaya tekan dari cetakan yang digunakan. AbstractOne important process in manufacturing pellet material is a compaction. This research will study the morphological structure of ZnO semiconductor material that is compacted with different pressure. The first material is pure ZnO which was rinded with agate mortar, filtered and compacted with pressure of 10 bar, 20 bar and 30 bar so the pellet form were shaped. The size of pellet was Ø 13 x 2 mm. Furthermore these pellet was sintered at temperature 1300oC and than tested by scanning electron microscope testing (SEM testing). The test results show that the morphological structure of a particle ZnO semiconductor material which was compacted at a pressure of 30 bar had an irregular morphological structure and no visible grain boundaries. When material was compacted, the space between the grains becomes very small and was unable to accommodate the enlargement of particles due to the sintering process so that it appears to fuse and become hard. Therefore, the greater the compacting pressure, the morphological structure of a particle becomes more dense and fuse. However, the magnitude of compacting pressure must be considered by considering the ability of the compressive force of the mold used.

Abstract

This final project makes a device that produces electrical energy by utilizing waste heat from injection machines. The waste heat of the injection machine is converted into electrical energy using a thermoelectric. This device consists of an aluminum heatsink, aluminum plate, thermoelectric, MDF wood planks, engine gasket, and thermal paste. The heat generated by the injection machine is received by the hot side heatsink, then 4 units of the thermoelectric and the cold side heatsink. Thermoelectrics are arranged in series. The output from the thermoelectric is connected to a multimeter to test the amount of voltage and current generated. The number of thermoelectric-based equipment made of 2 (two) pieces and assembled in series. The test was carried out using an open circuit and a closed circuit with a load using a 1 watt LED lamp (Ω 55 Ω). The open circuit test results show that the largest voltage is generated at 10.80 volts with a hot side temperature of 108C and a cold side temperature of 64˚C. The results of the closed circuit test show that the greatest voltage produced is 2.64 volts with a hot side temperature of 108 C and a cold side temperature of 62 C. When thermoelectric based equipment is given a load, the voltage decreases because the voltage is divided into the given load. This equipment can be applied to turn on as many as 5 lamps with a power of 1 watt each which supports production activities in the injection workshop.

Abstract

The technology that has been developed in recent years is the production of fusion welded plates between two different materials, for example, steel with other materials such as aluminum. Combining the two materials, aluminum and mild steel, will undoubtedly produce a material connection with good properties, for example, in a vehicle car frame. However, these two materials have different melting points, mild steel has a high melting point, and aluminum has a low melting point in the inner layer. This research aims to determine the welding results and the microstructure between aluminum plates and mild steel. The Cold Metal Transfer (CMT) welding process provides a potential method for joining dissimilar metals. In this study, various 4 mm thick aluminum alloys (Al 1100) were joined to 4 mm thick mild steel (SPHC) by CMT welding technology. It was concluded that combining aluminum alloys with mild steel using the cold metal transfer method was feasible. The optimum process variable for welding aluminum-mild steel dimensions 250 mm × 100 mm × 4 mm can be obtained with ER70S-6 wire, ArCO2 shielding gas, wire feed speed 13 m/min, and welding speed e8 mm/s.The tensile strength of the joint first increases and then decreases as the welding current increases, the highest tensile strength can reach 73.35 MPa.

Abstract

LGV (liquefied gas for vehicle) is one of the alternative fuel, which prioritized for a fuel diversification program of transportation sector in Indonesia. Having different characteristics and properties of gasoline fuel, the use of LGV fuel will have an effect on the working parameters of an engine. Based on that, this research is conducted to analyze the effect of using LGV fuel at a mass air flow rate and fuel rate in passenger cars. Through this research also expected as an act to support the diversification fuel program that proclaimed by Indonesia Government. Passenger cars used in this research have a different engine capacity, i.e., 1200 cc and 1500 cc. Measurement of mass air flow rate and fuel rate are performed with the throttle position variation (absolute throttle position) from 14% to 30% on third gear. The results obtained indicate that there is a decrease in air and fuel flow rate of 4% for the test car Honda Mobilio (1500 cc) and 2% for Mitsubishi Mirage (1200 cc). In addition, the air fuel ratio (AFR) of LGV fuel has the same range like fuel petrol mixing, the value of the measured air fuel ratio is 14.4-14.8 for Honda Mobilio and 13.5-14.6 for Mitsubishi Mirage. The lower value of fuel flow rate than gasoline fuel, prove that the use of the LGV fuel is more efficient and cheaper (due to the LGV price) than gasoline. In addition, LGV fuel also more environmentally friendly than gasoline fuel as seen from result of emission testing done by the most researchers.

Abstract

One of the processes commonly used in making plastic goods is the injection molding process. Every process in injection molding has a very important role. A less-than-perfect process will result in defects or failure in the product. To reduce product defects, one of the processes that must be researched is the barrel purging process. The purging volume on the mini injection machine using the V-line method is inconsistent, as evidenced by the fact that if the purging waste, or what is usually called an avalanche is weighed, it will produce a non-uniform mass. This research uses a mini injection machine with the V-line method which has 2 main steps to carry out the plastic injection process; dosing and injecting. Unlike injection engines in general, this engine does not have a check-ring to withstand back pressure. This machine uses a shut-off system as a replacement for the check-ring role. This machine has never been subjected to a purging volume consistency testing process. The consistency of the purging volume greatly influences the product uniformity results. The research method used in this final assignment is direct. Data collection and test specimen collection will be taken directly on the mini injection machine using the V-line method. The steps taken in this research are planning, taking data, taking test specimens, processing test specimen data, and comparing test specimen data to obtain analysis results. The research results show that the mini V-line injection machine cannot support mass production, because increasing the screw rotation speed will affect the consistency of the volume of plastic that will be produced in the barrel, causing production to not run quickly and precisely.

Abstract

ATMI Duta Engineering company is a manufacturing company engaged in the field of sheet metal with a material cutting process using laser cutting technology. Sheet metal products produced at ATMI Duta Engineering company is very diverse, one of which is the base cabinet. The base cabinet has main components, one of which is the shelf. Based on the data obtained from the interview process, there are problems, namely the shelf has never been analyzed, there are no finished products, and there is a risk of damage due to excessive loading. The solution to the shelf problem is to carry out a shelf design analysis using the finite element analysis method through Solidworks CAE software. The CAE simulation was applied to 27 variations of the shelf design by combining 3 test variables, namely the shelf model, the reinforcement model, and the thickness of the material. The material used in the simulation is SPCC material with a thickness of 1mm, 1.2mm and 1.5mm. The CAE simulation results obtained are then compared with reference to the SEFA 8M-2016 standard. The loading given in the CAE simulation is ± 108 kg (1.2 SEFA standards). The strongest variation obtained from the elimination process is variation 19 with a combination of shelf model 1 design, reinforcement model A, and with a material thickness of 1.5mm. Variation 19 meets the SEFA 8M-2016 standard because the displacement value is 1.065mm and this value is smaller than 6.35mm.
