Abstract

The auto level buff machine spindle shaft is a transmission shaft that continues rotation to the buff wheel. This shaft is subjected to a combination of bending and twisting loads, so it is necessary to design analysis regarding the strength of the shaft so that failure does not occur during use. The shaft design analysis will use manual calculations with reference to the failure theory which is then compared with the calculation results based on CAE simulation. The CAE software used are Solidworks Simulation and Ansys Workbench. Based on the results of manual calculations and simulations, there is a difference in Von mises stress, deflection, and safety factors. The results of the design analysis show that the shaft receives an equivalent stress of about 19 MPa and a deflection of about 0.088 mm. The safety factor that occurs is in the range of number 14 which exceeds the minimum safety factor of 1.5. It can be concluded that the spindle shaft design on the auto level buff machine is safe to use.

Abstract

Biogas is an alternative energy that has great economic value for rural communities. In practice, the CH4 biogas content is the most important part of the energy conversion process, but the impurities in the form of carbon dioxide which reduce the heating value is still large. So that efforts are needed to reduce CO2 by purification.The purpose of this study is to obtain a way of purification that improves the quality of biogas with high heating value and low CO2 impurities. The use of tile-type powder adsorbents, namely fine and coarse, which were studied at intervals of 5 and 20 minutes, for data retrieval of heat value and CO2 content. Gas Chromatography - Mass Spectrometry (GCMS) is used to test the adsorption gas content. The results showed a finer type of tile powder size gave better purification results with results at minute 5 and 20 respectively of 24.1 and 20.1% while on the type of grain size coarse at minute 5 and 20 each produced CO2 levels of 23.1 and 20.8%. Due to a decrease in CO2 levels the biogas calorific value after the highest purification is 23893 kJ/ m3 after the purification process which has resulted in a decrease in CO2 levels known during the purification process takes place the largest absorption effectiveness is 59.8% in the type of fine size within 20 minutes. The finer the size of tile powder, the heating value increases

Abstract

Falls are a major health problem around the world, especially in the world of healthcare because patient falls are the top worst problem that continues to occur. Most patients who fall out of bed are not witnessed. This is exacerbated by the various health problems that can result from falling. Remaining on the floor after a fall can cause trauma, serious injury and even death. Therefore, a fall detection system is needed so that people who fall can be given immediate help before they cause serious health problems. So in this study, we will create a fall identification system based on sound and image using the MFCC (Mel-Frequency Cepstrum Coefficients) method for sound extraction and LVQ (Learning Vector Quantization) for classification. Image processing using CNN (Convolutional Neural Network) method. In this system, both do not work together, but image processing works after sound processing. The system is able to detect falls with an overall accuracy of 93.3% for 15 times of sound and image processing tests.

Abstract

To support advanced material research, a machine that can perform wear testing is needed, one of which refers to the ASTM G65 standard. This journal contains the process of making the design of ASTM G65-based wear test equipment with the scope of design, construction, validation and verification. Validation at the design stage is carried out by vibration analysis using Ansys software. From the data obtained, transmissibility analysis was carried out so that it can be validated that the vibrations that occur in the engine are safe and do not interfere with engine performance. Next, the prototype construction of the ASTM G65 engine was carried out and continued with validation and calibration to conform to the ASTM G65 specifications. Then a wear test is carried out on a material to find out that the machine is working according to the test scheme. Verification of the test results is carried out by comparing the test results with the tests that have been carried out on other scientific studies to ensure authentic test results.

Abstract

Plastic has a very big role in everyday life, usually used for household needs, and in the automotive industry. One of the most widely used types of plastic is polypropylene (PP). Polypropylene (PP) has unique properties, flexibility, and a relatively low melting point that makes it stand out as an excellent material for a variety of applications such as ropes, hinge caps, food packaging, and the automotive industry. The addition of dyes to plastic materials can affect the good properties of plastics, one of which is tensile strength. In general, the addition of dye is given as much as 1 kg of granulated dye compared to 25 kg of plastic (4% granulated dye). This study aims to determine the tensile strength of polypropylene (PP) plastic material with the addition of 1%, 5% and 15% dye. So, it is necessary to test to assess the tensile strength which consists of 3 (three) components, namely: 1. Yield strength. 2. Maximum tensile strength and 3. Modulus of elasticity. The manufacture of product specimens uses the ASTM D638 standard and is made using the injection molding process. The values of yield strength, maximum tensile strength and modulus of elasticity on plastic materials without added dye were 30.02 N/mm2, 42.47 N/mm2 and 0.43 GPa. While the addition of dyes of 1%, 5% and 15% respectively the values are 1. Yield Strength of 32.53 N/mm2, 30.59 N/mm2 and 28.29 N/mm2, 2. Maximum tensile strength of 46.13 N/mm2, 45.33 N/mm2 and 41.57 N/mm2, 3. The elastic modulus are 0.58 GPa, 0.55 GPa and 0.42 GPa. The results showed an increase in the value of yield strength, maximum tensile strength and modulus of elasticity at the level of addition of 1% dye, but the value decreased with the addition of dye by 5% & 15%.
