Abstract

This research was conducted to obtain maximum design results through the QFD (Quality Function Deployment) method as an initial reference that must be considered at the design stage. Conducted to determine consumer needs for products made. Followed by the DFMA (Design For Manufacturing and Assembly) method to get the design results that match the needs and improve the efficiency of the designs made to the time of manufacture and reduce the cost of materials that are not needed. Then at the final stage, a stress analysis simulation is carried out using Solidworks software to determine the maximum stress received due to the given load and can determine the safety of the table frame strength that will be loaded and find out the maximum load that the frame can accept. The material used in the frame is ASTM A36. From the results of this study, it was found that with a given loading of 600 N, the frame experienced a maximum stress of 161.1 Mpa and a yield stress of 257.76 Mpa was obtained and a safety factor of 1.3. So with these data the frame design that has been made is declared safe. And for the maximum load that the frame can accept is 97.88 kg.

Abstract

Nowadays, working with production machines is very much needed in the manufacturing industry. The surface roughness produced by the machining process determines the quality of the workpiece components. Surface roughness can be influenced by factors, namely, feeding speed, cutting speed, and depth of cut so that these factors greatly affect the surface quality. Several conclusions can be drawn: Variations in Feed Rate and Spindle Speed ​​dosnt have an influence on the level or value of the surface roughness of the Nylon specimen. the smoothest or best is at Fr 400 mm SS 1910 rpm with a roughness value of 1.377 µm and the roughest at Fr 800 mm SS 636 rpm with a roughness value of 4.114 µm. at Fr 400,600,800 mm, SS 1910 rpm produces an average roughness of 1,505 m , At 400,600,800 mm, SS 1273 rpm produces an average roughness of 1,968 µm, At 400,600,800 mm ,SS 636 produces an average roughness of 3,301 µm.

Abstract

This study aims to make a rubber-based fire seal with a diameter of 32.60 mm using a Compression Molding tool. Compression Molding itself is a set of printing tools by heating and pressing. The scheme of the basic processes consists of heating a charge (thermostat and reinforcement) to a certain temperature, in the mold cavity and then pressing it with a certain pressure.The first process begins with tool preparation and mold making, then rubber is made into a 32.60mm diameter fire seal. After everything has been prepared, then cut the rubber into small pieces to meet the volume of the seal in the mold and put the rubber into the mold. Press the mold using a  re using the thermostat. After completion, the measurement of seal shrinkage includes the inside diameter, outside diameter, and seal thickness and then compared with the mold size, so that conclusions can be drawn. The calculation is influenced by the density of the structure after the testing process.

Abstract

The brake handle is one of the components to restrain the vehicle's movement rate by holding the clamp mechanism, the problem that exists in the brake handle when there is a hard impact. Handles are usually made with aluminum metal material, so that aluminum has certain properties in this study combined with magnesium elements with variations of 1%, 3%, and 5%. Magnesium is the lightest chemical element among other industrial metals. The low density value and strength of magnesium is an advantage of this element as an alloy. The alloy used is a metal casting process using the sand casting method. After combining aluminum and magnesium in a bending test to get an acceptable bending strength. The percentage value of magnesium has a significant effect with a comparison of Fcount > Ftable value 72.29 > f0.0001(2;9) = 4.26. The percentage factor obtained is 87% and the maximum value is 38.08 kg/mm2 and the minimum value is 30.46 kg/mm2.

Abstract

Indonesia is a country that has a variety of energy resources, both non-renewable and renewable. Development is progressing rapidly, as well as a very large population, of course resulting in a very large need for energy support. According to data owned by the World Bank, until 2020 alone Indonesia already has a population of 237.5 million. According to a report from the Riau Provincial Regional Energy General Plan (RUED-P) for 2020, the potential for New Renewable Energy (EBT) owned by the Province Riau itself consists of 6 types, namely geothermal, water, biomass, solar, wind and sea which can be utilized as electrical energy which is estimated to reach 5.9 gigawatts (GW). According to the Riau Energy and Mineral Resources (ESDM) Office, it is known that there are still 11 villages in Riau that did not have electricity until 2020, one of which is Kelapa Patih Jaya village. Based on the simulation using HOMER, the optimum hybrid power plant configuration is obtained consisting of 1 wind turbine and 10 batteries, with an inverter and biomass of 10 kW each

Abstract

Technological developments move very quickly. Machines are one of the technologies that were created, from existing machines being innovated according to the needs of the times, one of which is 3D Printing. This machine has a special sophistication, which is capable of printing in the form of a prototype whose form is with a drawing on the design in a CAD/CAM application. using Acrylonitrile Butadiene Styrene material. The reason for this test is because the cost of mold production is cheaper than using a molding machine that is commonly used in general, the level of precision is higher than making molding using conventional machines. The method of analysis used the experimental method to determine the effect of treatment on other factors under controlled conditions. Where the resulting mold is tested for surface roughness. From the test results, the data used will be obtained in the form of statistical data analysis, which is carried out using the Analysis of Variance (ANOVA). The analysis that has been applied, concluded that the layer height: low, standard, high has an effect on the roughness of the printed molding, and it can be proven by Fcount 13.026 > Ftable 2.56. with a significant 0.014 < 0.05. The lowest roughness results are printed using a layer height: 0.16 mm/s (high quality).

Abstract

The purpose of this study is to find out what chisel is the best for cutting acrylic resin and evaluate which one is the best, which can be seen from the surface roughness value obtained through the cutting process. The workpiece materials used in this study are acrylic resins and various types of chisels, namely HSS, carbide and tungsten, Because the chisel has different characteristic properties, so it can be used as a comparison. For the next process, the workpiece is fed three times with a spindle kec of 1000 rpm and a cut kec of 400 mm / minute and a feeding depth of 0.5 mm. It can be concluded that the surface roughness data of the workpiece, the value of the surface roughness of the workpiece of acrylic resin is averaged from the smoothest to the roughest, namely HSS, tungsten chisel, and the roughest carbide. The average roughness value of the HSS chisel is 0.751 μm and the average roughness value of the tungsten chisel is 1.578 μm and the roughness value of the carbide chisel is 1.768 μm.

Abstract

Various innovations have been developed by researchers to obtain and develop new natural fibers because of its advantages. Some of the advantages of natural fibers such as excellent physical properties, abundant natural materials, do not damage the environment and lower production costs. This study aims to produce alternative natural fibers by utilizing fiber from oil palm fruit which is commonly found in South Sumatra. The research was carried out by preparing resin and catalyst with a ratio of 100 ml: 1 ml which was then poured into the mold as much as 25% and continued by arranging palm fruit fiber randomly. After 8 hours, the resulting composite material is soaked for 2 hours with NaOH alkaline liquid with variations of 0%, 5% and 7%. The mechanical properties of the palm fruit fiber composite increased after being treated with alkali, where the highest values ​​were tensile strength 22.46 N/mm2, impact strength 0.15 J/mm2 and bending strength 87.50 N/mm2 obtained at variations of alkaline NaOH of 7 %.
