Abstract

Technological developments are increasing day by day in the automotive world. The use of vehicles is always accompanied by fuel, where the fuel is used in the combustion process in the cylinder which will cause heat in the engine. The engine temperature must be stabilized with the cooling system to produce optimal engine performance. If the heat does not get good cooling, it will cause changes in the mechanical properties and the shape of the engine components. The nature and components of the machine when it has changed will cause the engine components to be disrupted and reduce the service life of a machine. This study used an experimental method, while the analysis method used a one-factor variation analysis processing by varying the three types of water coolant with rpm variations of 1000, 1500, 2000, and 2300. Measurements were made by measuring the temperature at the inlet and outlet temperatures of the radiator. The variables used in the study these are the heat transfer rate, the overall heat coefficient, and the effectiveness of the fluid.

Abstract

The Savonius-Darrieus turbine is a vertical axis wind turbine which has a shaft arranged perpendicularly parallel to the wind direction, so that it can receive wind from all directions. This research was conducted by modifying the L-shaped blade angle with variations in the angle of curvature of the turbine blade as many as 3 angle variations, namely 10⁰, 20⁰, and 30⁰ respectively, also simulating wind turbines using the CFD (Computational Fluid Dynamics) method with a variable wind speed of 2 m/s, 2.1 m/s, 2.4 m/s, and 2.5 m/s. From the graph of the relationship between wind speed and maximum velocity, and the graph of the relationship between wind speed and maximum pressure, it can be seen that a 30° blade angle wind turbine has the highest maximum velocity value with a value of 4,387 m/s^-1 at a wind speed of 2.5 m/s. A 20° blade angle wind turbine has the highest max velocity value with a value of 4,288 m/s-1 at a wind speed of 2.5 m/s. A 10° blade angle wind turbine has the highest maximum velocity value with a value of 4,280 m/s-1 at a wind speed of 2.5 m/s. The 30° blade angle wind turbine has the highest maximum pressure value with a value of 4.111 Pa at a wind speed of 2.5 m/s. A blade angle wind turbine of 20° has the highest maximum pressure value with a value of 4.795 Pa at a wind speed of 2.5 m/s. The 10° blade angle wind turbine has the highest maximum pressure value with a value of 4.105 Pa at a wind speed of 2.5 m/s.

Abstract

The conventional process of printing meatballs using hands and spoons is considered less efficient in the production process both in quality and quantity. Meanwhile, commercially available meatball printing machines are bulky and complicated to use. Therefore, the design of a meatball making machine that has smaller dimensions can be developed at a more affordable price. This research began by designing a meatball printing machine using the SolidWorks software, with a frame design made of U-profile iron, meatball containers made of stainless steel cylinders, and packaging boxes for the electrical system from the relay. In the operation of the meatball molding machine, pneumatic is used as a drive system with a time delay relay to control the time for cutting the meatball dough. The manufacture of this machine produces a pneumatic-based meatball molding machine with constant pressure, with an automatic system using a time delay relay of 2 seconds for cutting forward and 0.2 seconds for cutting backward. From testing the machine applying a mass of 2.5 kg meatball dough, 192 meatballs were obtained, with a processing time of 7 minutes 29 seconds, with a remaining dough mass of 4 ounces, and an average meatball diameter of 24.95 mm.

Abstract

The aim of this research is to modify the coffee bean husking machine to enhance the quality and efficiency of the husking process. The modifications include the addition of a spring mechanism in the grinding space, enabling the outer roller to move flexibly in accordance with the size of the entering coffee beans. Furthermore, these changes also consider reducing the percentage of broken coffee beans during the husking process. The machine underwent two rounds of testing, with three samples tested under two different drying conditions. The research results demonstrate the success of the modifications in achieving their objectives. The machine's capability to husk coffee beans up to the parchment layer, not just the husk, indicates an improvement in the quality of the husking process. The quantity of successfully husked coffee beans also increased, while the percentage of broken beans decreased. By enhancing the quality and quantity of coffee beans produced by this machine, the modifications can significantly benefit coffee farmers. Additionally, this study utilized Autodesk Fusion 360 software to enable virtual assembly of machine components before physical production. The outcomes of the virtual assembly aided in understanding the machine's functionality and the interactions among its components. Therefore, the modifications to the coffee bean husking machine have assisted coffee farmers in producing higher-quality beans and expediting the coffee processing process.

Abstract

Testing the torque of a motorized vehicle, especially two-wheeled motorized vehicles (motorcycles), often requires equipment that is considered expensive and difficult to access on a small laboratory scale. However, the torque test is considered important to find out how a motorbike works using certain fuels, for example widely used fuel mixtures such as gasoline mixed with certain vegetable oils, to find alternative fuels. Therefore, a simple torque test tool is needed that can be designed and used as a preliminary study of alternative fuels. In this study, designed a simple eddy current-based torque test frame with a roller conveyor. Before the frame is formed, the frame design is outlined using the student version of ANSYS software to study the loading characteristics and promises. The simulation results show that the frame design can be used with a loading force of 294 N in the eddy current area and 981 N in the roller area. The frame was then manufactured using hollow iron measuring 4x6 cm with ASTM A500 material type. This research has succeeded in designing and producing a simple eddy current-based torque test frame using a roller conveyor.

Abstract

In the metal heating process, a tool is needed that can help the heat treatment process, namely a furnace where there is a space inside to warm up the workpiece to a certain temperature and hold it for a certain time interval. In this study, the furnace design was carried out using Autodesk Fusion 360 software, while the manufacture of the furnace uses several components such as A1 kanthal wire as a heating element, SK34 refractory brick, and Castabel C16 cement which is used as a heat retaining material. Performance analysis is carried out by calculating the speed of reaching the maximum temperature that can be achieved, the time required to reach the maximum temperature, and energy consumption. Based on the results of design and calculation, a furnace with external dimensions of 40x30x40 cm and heating chamber dimensions of 18x18x18 cm was produced. Furnace trials were carried out by melting aluminium material where the melting point of the material in its pure state is 660oC. Further tests carried out show that the maximum temperature that can be reached is 700oC, while the time required to reach that temperature is 50 minutes with an energy consumption of 2,404.6 Watts.

Abstract

One of the main components in IoT-based devices is sensors. Polyaniline is a conductive polymer that has great potential to be developed as an active layer for chemical sensors because it has high sensitivity, is easy to synthesize and its electrical conductivity can be adjusted. This study aims to synthesize and characterize polyaniline using the interfacial polymerization method. In this study, polyaniline was synthesized by varying the aniline concentration of 2, 3, and 5 M, then its functional groups were characterized using FTIR and its conductivity and sensitivity were measured with an LCR meter. The result shows that polyaniline is in the form of emeraldine salt which is characterized by the formation of absorption bands at concentrations of 2, 3, and 5 M, respectively, 1,141.86 cm-1, 1,139 cm-1 and 1,139.93 cm-1. The highest conductivity was obtained at a concentration of 2 M, namely 4.9x10-5 and a sensitivity of 82.8% for an ammonia concentration of 100 ppm. So it can be concluded that the polyaniline obtained is a form of semiconducting emeraldine salt.
