Abstract

Thermal spray coating is a material protection process by depositing the coating material on the substrate material. Process parameters such as spray-off distance, surface roughness, and substrate preheat temperature, spray time, voltage, and arc current greatly influence the mechanical and tribological behavior. Selection of appropriate process parameters and coating materials must be carried out to obtain a coating that meets the design requirements. The coating method used is electric arc spray with parameters: spray-off distance of 200 mm, compressor air pressure of 7 bar, voltage of 32 volts, and layer thickness of 1 mm. At the same time, the independent variables are arc currents: 159, 185, and 299 amperes. The substrate material is AISI 1045 steel, PMET 885 intermediate material, and PMET 720 coating material. The tests carried out were observing the microstructure, hardness, wear rate, and corrosion rate. This research shows that the higher the arc current, the better the coating quality. At an arc current of 229 amperes, it is known that the hardness, the wear rate, and the corrosion rate are 398.10 VHN, 8.96 x 10-8 gram/mm2.s, and 0.8911 mpy, respectively. This research's contribution is to provide a reference on the influence of the arc current of the electrical arc spray coating process on the tribological behavior of the surface layer so that suitable for the desired application.

Abstract

Utilizing alternative energy as an effort to use energy needs to be done. One is energy harvesting, which is capturing minute amounts of energy from one or more surrounding energy sources, collecting and storing them for later use. There are examples of uses in harvesting energy from vibrations, which are carried out using piezoelectricity as a converter into electrical energy. A piezoelectric-based electrical energy harvesting device has been designed using a cantilever method from mechanical pressure from humans climbing stairs. This research uses an experimental method where there are variations in the load given by humans of 55 Kg, 65 Kg, and 75 Kg to provide a force on an energy harvester that has four piezoelectric circuits installed, which are installed in series and parallel totaling 38 piezoelectric units. , where the four circuits have a number of piezoelectrics of 10, 8, 10, and 8 piezoelectrics on each side. The resulting voltage will later be rectified using a rectifier bridge until it is temporarily stored in the capacitor. As obtained from the calculation results, the voltage values for each load are 7.762 mV, 11.103 mV, and 17.55 mV, respectively.

Abstract

Technological advancements drive innovation in environmentally friendly material science. Environmental issues, such as pollution from toxic substances, motivate research into sustainable biocomposites. One of the widely studied biocomposites is a natural rubber-based composite with fillers that enhance its mechanical properties. Calcium carbonate (CaCO3) is a popular inorganic filler. Marine shell waste, especially cockle shells (Anadara granosa) and eggshells, pose serious environmental problems. Cockle shells contain 95.7% calcium carbonate. Eggshells also have the potential to improve the mechanical properties of elastomer composites. This study aims to compare the effects of cockle shell and eggshell fillers on the mechanical properties of natural rubber through tensile testing, to determine the more effective filler in improving the mechanical performance of the composite. Test results show that cockle shells have a higher ultimate tensile strength (UTS) (up to 20.3 MPa) and a higher Young's modulus (up to 3.4 GPa) compared to eggshells, which have the lowest UTS of 17.94 MPa and the lowest Young's modulus of 1.8 GPa. This indicates that cockle shells are stiffer. However, eggshells have a higher yield strength (up to 15.2 MPa), indicating better elasticity. Overall, cockle shells enhance strength and stiffness, while eggshells excel in elasticity

Abstract

One of the basic competencies that Vocational High School (SMK) mechanical engineering teachers must have is being able to draw technically using CAD (Computer Aided Design) based applications. This competency is part of the competency field of study expertise that teachers must have. From the results of observations in the field, it was found that there are still many vocational school teachers in Cilegon City who are still not experts in using CAD-based applications, one of which is SMKS YP Fatahillah 1 Cilegon. As a form of implementation of one of the duties and obligations of the Tri Dharma of Higher Education, the Mechanical Engineering Department of Sultan Ageng Tirtayasa University carries out a community service program, namely training in the use of CAD-based technical drawing applications at SMKS YP Fatahillah 1 Cilegon. This activity was carried out for 3 days and was attended by 24 participants who work as teachers and laboratory assistants at the vocational school. The training method is delivered by lectures, presentations and direct exercises and practice. From this activity, the results showed that there was an increase in the competency of the participants, namely in their ability to draw techniques.

Abstract

This study focuses on designing a touch-free door lock system based on Arduino, utilizing ultrasonic sensors, sound sensors, magnetic switches, and slot locks, following the Pahl and Beitz design methodology. The aim is to develop a reliable system that enhances convenience and reduces the need for physical contact with door locks. The results indicate that the ultrasonic sensor performs effectively in detecting distances, while the magnetic switch operates within a maximum reading range of 10 mm. However, the sound sensor demonstrated low accuracy, requiring multiple claps for successful detection. The findings suggest that the developed product functions as intended, though the limitations of the sound sensor highlight the need for further improvements to optimize precision and responsiveness.

Abstract

The exploration of natural resources as materials for engineering applications is increasingly important, as organic materials offer greater environmental benefits. The Maja fruit, a typical Indonesian plant, has not been fully utilized for engineering purposes, particularly its shells. The goal of utilizing this material is to contribute to sustainable development. In this study, Maja fruit particles were used as a filler in combination with rice husk ash. The particle compositions of Maja fruit were set at 20%, 30%, and 40%, respectively. The composite fabrication process was conducted under cold conditions at a pressure of 30 MPa. The results indicated that an increase in the composition of Maja fruit shell particles led to higher compressive strength in the composite, although this caused a decrease in surface hardness. The optimal composite performance was achieved with a composition of 40% Maja fruit shell particles and 60% epoxy resin, as determined by a weighting method. It was also observed that while the inclusion of rice husk ash tended to reduce compressive strength, it contributed to enhancing the hardness of the composite.

Abstract

Stress concentrations cause many machine element failures. Failure will occur more rapidly if the machine elements obtain repeated and fluctuating loading. For this reason, the material for machine elements must have better fatigue life. There are various attempts made to increase material life and other mechanical properties. In this study, the research sample used is AISI 4140 steel. The samples obtain hardening followed by cooling and tempering. The hardening temperature is 8500C with a holding time of 17 minutes. The cooling media in this research are dry sand, semi-wet sand, and wet sand. Wet measurements based on volumetric ratios. Semi-wet sand with a ratio of sand and water 4: 1, sandy sand 4: 2. The final process is tempering treatment, with a temperature of 2500C. The material fatigue test refers to the JIS Z 2274 Standard. From this study, the heat treatment given can reduce the fatigue life of the material, even though the hardness increases. The higher the cooling rate, the hardness of the material increases, but the fatigue life is low.

Abstract

Clean and healthy air are major topics around the globe. It is because poor air quality hurts human health and is even responsible for the deaths of millions of people. This work develops exhaust pipes containing filters to reduce the pollutants emitted by motorcycles. There are three pollutant concentrations measured here: CO2, CO, and HC. The measurements were taken before and after the filter system so that the pollutant reduction could be calculated.  The maximum pollutant reduction of the filter system: 6.1 % of CO2, 8.0 % of CO, and 651.0 ppm of HC. The primary mechanism of this filter is the physical trapping of pollutants. When the gas flows through the exhaust pipe, the pollutants in the stream are attached to the filter due to direct contact. This change can be visually observed in the filter color, which darkens after use in the exhaust pipe. However, a limitation of this work is its short-term experiment, which lasted only five minutes, indicating a key area for future research. It is also necessary to have alternative filters that are sustainable and can work properly in high-temperature conditions.
