Abstract

The use of coolant in the machining process aims to reduce the temperature in the cutting area and reduce friction due to friction between the workpiece and the tool which has an impact on the surface quality of the product. Commercial coolants such as Dromus oil use minerals, which are non-renewable and have a negative impact on the environment. Therefore, to overcome this problem, several studies have been carried out to replace or combine commercial coolants with vegetable oils. In this research, an experiment was carried out on the effect of using nyamplung oil ascutting fluidby mixing three different liquids (nyamplung oil, dromus oil, and water) (25%:25%:50%, 20%:30%:50%, and 30%:20%:50%) and the influence of the contribution of Turning machining parameters on tool wear. Machining was carried out on S45C steel using HSS type M2 chisels. This research method uses the Taguchi methodorthogonal array L9(33) with 3 factors (spindle rotation speed, coolant variation, and cutting depth). The results of this experiment show that a coolant composition of 25%:25%:50% (nyamplung oil:dromus oil:water) in 100ml of liquid contributes to reducing tool wear. Based on the average value, it shows that the highest parameter contribution is spindle speed at 60.26%, followed by cutting depth with 29.14% and coolant variation with a contribution of 9.40%.

Abstract

The use of composite materials as a substitute for metal materials in the engineering field has become increasingly widespread not only in the field of transportation panels but also in other fields such as property and architecture because alternatives have the advantage of using composite materials to be lightweight, corrosion resistant and strong and can be designed as needed. One of the methods developed to manufacture composite polymers is resin infusion with vacuum assistance. This method is inversely compared to the non-vacuum method. The (VARI) process requires an airtight space in printing and can reduce the fouling effects that occur in non-vacuum processes such as causing a lack of optimal composite material properties. The Taguchi method is a methodology in the field of engineering which is very much aimed at improving a product quality in a time process while at the same time reducing costs and minimal resources. The Taguchi method is a product or process that is robust against noise, therefore this method is a robust design. In writing this research, I have experience in the process of making and researching carbon in body organization in the Mechanical Engineering University of Jember named Tawang Alun, here I will conduct research in analyzing the optimal parameters for the surface roughness characteristics of front cover products made of carbon fiber using a vacuum process. resin infusion aid. The factor that contributes the most to the surface roughness response is vacuum pressure with a contribution of 25.20%. For hardener factor contribution of 14.93% and coating factor of 23.77%. The contribution error that occurs is 36.09%. Each factor has a value contribution that is not too different. Based on the data and analysis results that have been obtained using the Taguchi method with the help of Minitab 19 and Microsoft Excel, it shows that the parameter of vacuum pressure has a significant influence on the results of surface roughness. While the hardener parameter has no significant effect on surface roughness, then the coating parameter has a significant effect on surface roughness. In the calculation of the F test, it can be concluded that the optimal factor parameters in making a front top with a small surface roughness value are 0.4 bar vacuum pressure, 60% hardener and PVAC coating.

Abstract

3D printing is a process of making three-dimensional solid objects from a digital file process created by laying down successive layers of material until the object is created. Many filaments can be used in 3D printing, one of which is PETG (PolyEthylene Terephthalate Glycol). PETG is a modification of PET (PolyEthylene Terephthalate) with added glycol at a molecular level to offer different chemical properties that provide significant chemical resistance, durability, and excellent formability for manufacturing. This study aims to find the most optimal parameter of surface roughness of PETG with different parameters of nozzle temperature, infill geometry, layer height and fan speed. Taguchi L16 (44), with four levels for each parameter, was used to determine the effect of each parameter. Each experiment was repeated five times to minimize the occurrence of errors. Based on the result, the effect of each parameter is nozzle temperature at 4.9%, infill geometry at 5.9%, layer height at 82.3%, and fan speed at 4.6%. Layer height has the highest effect on surface roughness, and other parameters have a low effect, under 7%. Research shows that the optimal combination of parameters is a nozzle temperature of 220 °C, infill geometry zig-zag, layer height of 0.12 mm, and a fan speed of 80 %.

Abstract

Technological advancements in the industrial sector have led to rapid developments in 3D printing technology, enabling the creation of three-dimensional prototype models. Various filaments, including polyethylene terephthalate glycol, nylon, and polylactic acid, have been widely adopted in the industry. However, filaments composed of metal mixtures are relatively scarce in Indonesia, primarily available only through select online shops worldwide. The production and sale of such filaments present lucrative opportunities within the manufacturing industry. In this research, an experimental study was conducted to examine the hardness of test specimens fabricated using PLA-brass filament. The objective was to identify the optimal hardness value of the specimens. The study focused on three key parameters: nozzle temperature, layer height, and print speed, each at two different levels. The Taguchi L4(2³) experimental design was employed, along with S/N ratio and ANOVA analysis, to evaluate the results. The findings revealed that specific combinations of parameters yield favorable hardness values, as determined by the Taguchi Method. The optimal set of parameters for achieving good hardness values was determined to be a nozzle temperature of 230°C, a layer height of 0.2 mm, and a print speed of 40 mm/s. These results enhance the understanding of PLA-brass filament properties and facilitate the utilization of 3D printing technology in the manufacturing industry.

Abstract

The increasing need for energy and dwindling natural reserves encourage the search for alternative energy sources. One alternative energy source is biodiesel. Biodiesel can be produced from used cooking oil through the esterification and transesterification processes. However, biodiesel sourced from plant materials has disadvantages, one of which is its low calorific value. Most studies discuss the addition of chemical additives to increase the calorific value of biodiesel. However, the addition of ethanol vapor as an air additive to increase the calorific value of biodiesel is rarely discussed. This study was conducted experimentally, the study examined the effect of adding ethanol vapor to a diesel engine through an air filter. The diesel fuel used was dexlite type diesel fuel added with biodiesel from used cooking oil as much as 10% to 30%. Testing used additional ethanol vapor channeled through an air filter with a heating temperature of 90oC to 100oC. The results of the study were in the form of crankshaft rotation, effective power, and fuel consumption. The results showed that fuel with the addition of ethanol vapor produced the highest crankshaft rotation, effective power, and fuel consumption when compared to without the addition of ethanol vapor in all variations of the given fuel composition. The highest value of crankshaft rotation, effective power is in the B0 composition with values ​​of 32.53 rev/s and 2.74 kW, respectively. While the lowest fuel consumption is in the B70 composition with the addition of ethanol vapor of 105.7 seconds.
