Abstract

Quality of product in various industries, especially in metal industry is the most attention so the product can compete and attract consumers. Surface roughness is one of the demand that must be fulfilled because it can be the initiation of cracks, especially when material receives recurring and fluctuating loading. Therefore, low surface roughness can produce a product with longer lifespan material. The goal of this study is to determine the most optimal combination of electroplating process with factors variety of voltage (volts), temperature (℃), and time of immersion (minutes) to produce a low values of surface roughness. This study uses an experimental design with Taguchi method. Contribution factors of control that produce the surface roughness values ​​were influenced significantly by control factor voltage (volts) amounted to 77.31% with an average roughness value of 1.29 μm. This is due to the increase in voltage which causes the deposition of electrolyte ions which is faster in the deposition structure of the specimen. Where as other control factors were not effected significantly on the temperature control factor amounted to 4.85% with an average roughness value of 1,32 μm. These results are possible because the temperature variations used (40℃ to 50℃) are still within the optimum operating temperature. And the other control factors is immersion time amounted to 10.13% with an average roughness value of 1,32. The result ware obtained because the length of coating time affected the quantity of deposition of nickel ions on the surface of the specimen. The result of optimal condition is the voltage level 2 (6 volts), the temperature at level 2 (45℃), and the immersion time at level 3 (25 minutes).

Abstract

This research is aimed to provide insight on the dependency of tensile strength on process parameters of the Fused Deposition Modeling (FDM). FDM is one of the most popular 3D printing manufacturing techniques. In the present study, a tensile test was performed to measure the tensile strength of PETG (Polyethylene terephthalate glycol) specimen with the combination of different layer height, infill geometry, nozzle temperature, and fan speed whereas other parameters are kept at a constant level. This study uses the ISO 527 1BA standard. Taguchi L16 (44) with 4 levels for each factor was used to determine the effect of each parameter. Each experiment repeated 3 times to minimize the occurrence of errors. layer height, infill geometry, nozzle temperature, and fan speed ​​respectively effect of 13.4%, 63.6%, 19.0%, and 2.7%. Fan speed is considered a parameter that has no impact on tensile strength. The layer height and nozzle temperature parameter shows that the higher the value, the tensile strength of specimens tend to increase. Furthermore, infill geometry from the one with the highest to the lowest tensile strength value is gyroid, zig-zag, grid, and triangles. The combination of layer height of 0.24 mm, infill geometry gyroid, and nozzle temperature of 250 ˚C is the optimum combination of parameters which has the highest tensile strength of 34.76 N/mm2.

Abstract

To improve the performance of the WEDM process, it is necessary to adjust the WEDM parameter settings to optimize the material removal rate (MRR) by decreasing the electrode wire wear (TWR) value. Using SKD 61 steel as the material, the impact of peak current, voltage open, and wire tension on material removal rate and tool wear ratio is used to estimate the ideal level parameters. The study's findings should be able to offer suitable parameter settings for WEDM work. Peak current (Ip) of 63.7%, wire tension of 31.4%, and open voltage of up to 1.9% are the machining parameters that impact the material removal rate (MRR) in the wire cut electrical discharge machine process sequentially. Open voltage, which contributes 54.4%, the wire tension parameter, which contributes 36.5%, and the peak current (Ip) parameter, which contributes 7.8%, are the machining parameters that have the most significant cumulative influence on the tool wear ratio (TWR). Peak current parameter at level 3 (9A), open voltage parameter at level 1 (5V), and wire tension parameter at level 2 (8N) are the ideal settings for MRR and TWR, resulting in MRR values of 9.861 mm3/min and TWR as high as 0.078. The study's findings usually show that higher wire tension and peak currents enhance material removal rates because the jumps of sparks produce tremendous energy. In contrast to how to open voltage and wire tension affect the wear value of the wire, thicker wires erode more quickly because more tremendous energy is generated, necessitating ideal conditions for both responses. The results of the optimization of the two responses are produced by raising the maximum peak current, lowering the minimum open voltage, and figuring out the ideal wire tension.

Abstract

Silage is animal feed fermented to add nutrition and increase feed availability, especially during the dry season. The feed fermentation process is faster if the feed has been chopped before. This service aims to introduce choppers to Jelbuk Village, Jember Regency farmers. The service begins by discussing the problems faced by farmers/breeders, chaired by Mr. Mahfudz. They wanted a portable mini chopper to move and operate this machine at each member's residence. The chopper is modified from the previous multi-function chopper machine, which can chop leaves and twigs and crush animal manure for compost raw materials. Socialization of this machine is carried out simultaneously with training in making silage. After demonstrating the machine's operation and maintenance, the service partners were enthusiastic and rushed to try this new counter at their homes. They hope coaching activities can be continued later with the technologies they need.

Abstract

3D printing, also known as additive layer manufacturing, is a technique that creates three-dimensional objects or any shape from a digital model. It works by building objects layer-by-layer, similar to how a laser printer operates. Fused Deposition Modeling (FDM) is a widely used technique in 3D printing because it is easy to use, cost-effective in production, and environmentally friendly. This study focuses on a self-made filament made of a PLA-titanium mixture. PLA is a biodegradable thermoplastic polymer sourced from plants, whereas titanium is a strong, lightweight, and corrosion-resistant metal. To measure the hardness of different materials, there are several methods available. In this study, the Shore D hardness test, specifically designed for polymer materials, was used. Data were collected using the Taguchi method, specifically L4 (23), and the data were analysedusingAnalysis of Variance (ANOVA). The variations in print parameters examined in this study include nozzle temperature (230°C and 240°C), layer height (0.2 mm and 0.3 mm), and print speed (30 mm/s and 40 mm/s). The aim of this study was to determine whether there were any changes in the hardness of the specimens. The ANOVA results revealed that the most influential parameter was print speed, with a contribution value of 56.01%. The results demonstrated that the printing parameters affected the hardness of the printed specimens. The highest hardness level of 56.3 Shore D was obtained with a nozzle temperature of 240°C, a layer height of 0.3 mm, and a print speed of 30 mm/s. The application of this study was demonstrated through the creation of dentures made from PLA-titanium.

Abstract

Titanium is a biocompatible metal commonly applied in biomedical fields such as bone and dental implants. Recently, the produced titanium-Polylactic Acid (PLA) filament for 3D printing Fused Deposition Modeling (FDM) technique is easier to operate and affordable. This filament contains less than 20% PLA, which is also biocompatible but hydrophobic and capable of producing inflammation of the surrounding artificial living tissue. Therefore, a heat treatment is needed to reduce or even eliminate PLA. The research aimed to optimize the mechanical properties and biocompatibility of titanium-PLA filaments through heat treatment, demonstrating significant advancements in 3D printing applications for biocompatible materials. A Thermogravimetric Analysis (TGA) was carried out to find out the right temperature for reducing PLA levels. Specimens were heat treated with four temperatures at 100oC, 160oC, 190oC, and 543oC, and two holding times of 60 and 120 minutes. The mass of the specimens was weighed before and after heat treatment to determine the mass reduction and tested for tensile, micrograph, and fractography observation. The result is a meagre mass reduction. The highest tensile strength of the heat-treated specimen with a heat treatment temperature of 160oC and a holding time of 60 minutes is 18.310 MPa. However, it is still below the strength of the non-heat treated specimen, 19.890 MPa. Specimens with low tensile strength have a microstructure that shows an uneven distribution of titanium particles. Last, fractography shows porosity in the specimens with the lowest tensile strength.

Abstract

The increasing interest in coffee in all circles means that coffee production and quality must always increase due to consumer demands. One way to maintain the quality of coffee beans is by breaking them down using a huller machine. This research aims to improve the optimization of coffee machines by modifying the cylinder blades of huller machines with variations of 3, 4, 5, and 7 cylinder blades in terms of static loading design and quality and production capacity of coffee bean breaking. The experiment was carried out using 400 rpm and breaking 10kg of dry coffee cherries every time the sample was taken. The research results show that the best sample collection is the variation of 3 cylindrical blades with the maximum stress and lowest deformation values of 6.67 MPa and 0.000737 mm. In terms of production quality, it shows that the best sampling was the three cylindrical blade variations with 50% whole and good coffee beans. In terms of production capacity, the most significant capacity was the seven cylindrical blade variations with a value of 294.11 kg/hour. Sampling from the four most optimal variations uses the SAW (Sample Additive Weighting) method. The most optimal result from the 4 test criteria, the variation of 3 cylindrical blades is the best because it has the highest score with a value of 0.9754.

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.
