<![CDATA[Piping installation is a medium for fluid transfer which has many design variations. The design used can affect the flow rate of the fluid. The effect comes from head losses which are divided into major losses and minor losses. Basically, major losses are losses caused by straight pipes while minor losses are losses due to pipe components. These components can be in the form of bends, connections, branching and changes in cross-sectional size. Losses that occur in pipe flow can be studied by direct simulation. To carry out a direct simulation, a test tool is needed that can help analyze losses that occur in fluid flow in pipe installations. The design that is carried out refers to the use of pipe installations that are often encountered including its components. The system design of the flow loss test equipment is selected using the VDI 2221 method. The selection of components is carried out by comparing the variations in the arrangement of system components. From the results of this comparison, the best variation was obtained with the results of the main PVC pipe, 108 bit Shimizu jet pump, ball valve type, pressure gauge capacity of 2.5 bar, flowmeter capacity of 1.5 m3/h, rotameter capacity of 2-20 GPM/10- 70 LPM. The tool has been completed built and tested so it is feasible to use.]]>

<![CDATA[The automotive industry is growing rapidly. Produce changes, especially in the level of Safety and comfort. Vehicle manufacturers are competing to improve the quality of the components used in these vehicles. One aspect of Safety and comfort is the Safety and comfort of the vehicle's wheels, in addition to an attractive wheel design. Therefore, the material used on the wheels is high-quality, with precise calculations and correct designs. Vehicle wheels are one of the main components in vehicles because vehicles without wheels cannot run. There are two kinds of wheels: spoke wheels (spoke wheels) and cast wheels. This study aims to determine how to design cast wheel wheels type MT and WM and analyze material comparison and the number of spokes based on simulation using the software. The simulation results show the design of the MT-type cast wheel: the maximum stress value on the 7050-T7651 aluminum alloy material is 426.784 MPa, and on the 7075-T6 (SN) aluminum alloy material, which is 426.784 MPa, it is still within the safe limit because it is still below the value yield strength. In the design of the WM-type cast wheel, the maximum stress value on aluminum alloy type 7050-T7651 is 362085 MPa. On aluminum alloy material type 7075-T6 (SN), which is 362,085 MPa, it is still within safe limits because it is still below the yield strength value. The maximum strain value for the two materials used is 3.987 x 100-6, and the maximum displacement value for both materials is 9.959 x 100-4. The highest factor of safety value on WM 5 spoke wheels with aluminum alloy type 7050 –T7651 is 1.76]]>

<![CDATA[Natural fibers can be employed to enhance the strength and rigidity of composite structures. These fibers can be combined with matrix materials to create composite materials. One specific example of a natural fiber is coconut fiber. Unfortunately, coconut fiber is currently underutilized, leading to organic waste. However, coconut fiber offers several advantages as a substitute for automotive product composites despite facing specific technical challenges. Hence, it is important to understand the potential of coconut fiber composites with epoxy and polyester matrices. This study aimed to assess the capabilities of coconut fiber composites with epoxy and polyester matrices through a torsion test. The study involved conducting torsion tests on composites with varying volume fractions, precisely 25:75, 30:70, 35:65, and 40:60 (coconut fiber fraction to polyester/epoxy fraction). The research entailed creating torsion test specimens and performing the torsion tests. Subsequently, an analysis of the torsion test results was conducted. This research indicates that coconut fiber with an epoxy matrix demonstrated a maximum stress value of 31.27 MPa and a maximum shear strain value of 1.022 rad at a 30% volume fraction. Similarly, coconut fiber composite with a polyester matrix exhibited a maximum stress value of 27.83 MPa and a maximum shear strain value of 0.91 at a 30% volume fraction. Based on these outcomes, it can be concluded that the optimal volume fraction of coconut fiber for producing satisfactory specimens is 30%, regardless of whether the composites have epoxy or polyester matrices.]]>

<![CDATA[Solder Dross Recycle (SDR) machine role is to extract solder out of solder dross. SDR machine has two parameters which are working temperature and controller type. There are three working temperature references which are 220 °C, 250 °C, dan 298 °C. Controller type of the machine are available for two options which are ON-OFF and PID controller. The aim of this research is to determine working temperature combination and controller type. The SDR machine is tested with variations of working temperature and controller type. Data needed for choosing the best working temperature are extracted solder mass (ESM) and energy consumption (EC). EC is obtained from measurement by digital power meter, while MST is obtained by measuring final solder weight. EC is divided by MST to obtain Specific Energy Consumption (SEC). Data needed for choosing the best controller type is electrical power which is recorded every 10 minutes. Testing period is decided to be 200 minutes. The result of working temperature testing showed that the bigger the working temperature the smaller the KES so that the suitable working temperature in this experiment is 298 °C. The result of controller type testing showed that the smallest SEC was in PID controller with the working temperature of 298 °C which is 0.55 kWh/kg. The SEC value of 0.55 kWh/kg is less as much as 10.9% than the smallest SEC value of ON- OFF controller whose working temperature is 298 °C which is 0.61 kWh/kg. The chosen working temperature based on SEC is 298 °C with SEC of 0.55 kWh/kg out of 220 °C and 250 °C. The chosen controller type is PID controller with SEC of 0.55 kWh/kg with setting of Kp. Ki, and Kd respectively are 9, 250, and 7 out of ON-OFF controller with hysteresis setting of 0.5 °C.]]>

<![CDATA[In this journal, the author reviews the performance improvement of vapor compression refrigeration machines by adding nanoparticles into the refrigeration system using CFD simulation. This study aims to determine the improvement of refrigeration machine performance by adding nanoparticles into the refrigeration system using CFD simulation and to compare the simulation results with the experimental results. Where the method used in this study is a literature review. The results of the literature study show that the dispersion of nanoparticle additives can affect the increase in the refrigeration system performance coefficient (COP) and can maximize thermal conductivity, heat transfer coefficient, and other heat transfer characteristics so that it can produce lower power consumption. Using the CFD simulation method, the highest increase in refrigeration system performance was obtained through the simulation of SiO2 + R134a nano refrigerants with a volume concentration of 4% and an increase value of 22.58%. From the experimental results, the highest value was obtained by Al2O3 + R134a nano refrigerants with a volume concentration of 0.5% and an increased value of 30.85%. The system's performance showed a significant improvement with the addition of nanoparticles. Therefore, the performance of the refrigeration machine with the addition of nanoparticles in the refrigerant fluid is higher than the system using pure refrigerant fluid (without nanoparticles).]]>

<![CDATA[Exergy analysis of power plants that utilize exhaust heat at Cemen plant was carried out to identify the reliability of the generator as a whole system or for each component that could be used as a basis for optimizing the utilization of exhaust heat and optimizing the operation of the generator to make it more efficient with increasing usage life. The exergy flow and efficiency are calculated for each component, and the data is then used to calculate how much exergy is destroyed in each component. Calculations are also carried out on the system at the time of commissioning in order to get how much the exergy efficiency has changed since the system was operational. The components of this plant include an SP boiler, AQC boiler, turbine, condenser, condensate pump, Flasher, boiler feed pump, and economist. AQC boiler is the component with the highest exergy value that is destroyed, which is 4405.34 kW or 32.98% of the total exergy destroyed in the system. The condensate pump is the component that has the smallest destroyed exergy value of 18.94 kW (0.14%). The system efficiency in January 2012 was 62.60% and decreased in December 2019 to 53.04%, where the overall system exergy efficiency decreased by 9.56% within 7 years of operation.]]>

<![CDATA[Steel has various physical and mechanical properties. The very high hardness of steel makes it difficult to form or process with a machine. Based on these problems, there needs to be a treatment (treatment) that can improve the mechanical properties of steel. The annealing process is the process of heat treatment of metals or alloys by heating the metal to austenite temperatures, holding it at that temperature for a while, and cooling the metal at a very slow cooling rate. The heat treatment process aims to improve the mechanical properties of the metal or alloy. In this study, SUH 35 steel was used as the test material. Eight test materials are prepared, namely four materials Unannealed and four materials treated with annealing. Annealing specimens are given heat treatment with a temperature of 750 ° C ± 10 ° C with a holding time of 60 minutes. This specimen is carried out by turning process with variable machining feeding that varies 0,25 mm/revolution, 0.50 mm/revolution, 0,75 mm/revolution, and 1 mm/revolution. The results of this study show that the annealed material has a lower roughness value of 311.49 VHN. In comparison, the Unannealed sample has a hardness value of 607.59 VHN, which shows better machinability in the annealed material. The results of the feeding variation show that the greater the feeding value, the more it will affect the increase in the roughness, resulting in the surface grinding process.]]>
