<![CDATA[This literature review study is motivated by the important role of the piping system in determining production results in an industry. The fluid flowing through the piping system experiences instability, resulting in Head Losses. As a result, the fluid pressure is lower than desired, resulting in suboptimal system performance. The aim of this study is to identify a research gap concerning a review of the design of Head Losses test equipment that has been made by previous researchers. The analysis was conducted by literature review using the systematic literature review (SLR) method. Based on a review from 30 journal, it was found that to design a head losses test equipment in a pipe installation, a person must have a basic knowledge of fluid mechanics. Furthermore, an understanding of the function of pumps, pipe installations, pressure gauges, and measuring instruments that are part of the functional system in this test equipment is required. These are the author's references for designing flow loss test equipment that will be used in the Mechanical Engineering Laboratory at Mercu Buana University's Faculty of Engineering.]]>

<![CDATA[Currently laundry service providers are mushrooming, this is because most people are busy with office work and activities, while homework cannot be ruled out, for example washing clothes. Cleanliness of clothes is an absolute thing that must be achieved. The thing that most influences the cleanliness of laundry results is the right amount of water and the appropriate detergent capacity. If the detergent capacity is adjusted to the water capacity and number of clothes, maximum results will be obtained. To overcome this, a detergent pump with fuzzy logic was made for the control system. Fuzzy logic provides a limit on the detergent volume adjusted for the input of water volume and the capacity of the clothes to be washed. For input data taken using a flow meter sensor to measure the volume of water used and a potentiometer to provide input weight of clothes to be washed. From the input data, the fuzzy logic method will produce detergent volume according to needs, so there is no excess detergent volume that can cause damage to clothes and reduce the live time of the washing machine. With a pump using a peristaltic pump, the resulting detergent volume is expected to be more stable. With the results of three volume variable experiments namely 20ml, 40ml, and 60ml obtained a maximum error data of 4.01% of the expected volume, the deviation of the desired detergent volume is not too much, so it is expected to reduce excess expenditure on the use of detergent. As for the fuzzy logic method that is applied can provide output results that are adjusted to changes in clothing weight between 5kg - 15kg and changes in the volume of water used between 37L - 56L so that it is expected to provide optimal results during the washing process. The system is designed using a maximum voltage of 12V DC and 3A current making this device low-power only 36 watts. This tool does not consume too much electricity.]]>

<![CDATA[Fossil fuels are still a daily necessity in the world. Human dependence on fossil fuels has created problems related to pollution and energy security. Wind turbines are renewable energy power plants where their use is expected to be an unlimited alternative energy source. This wind turbine research uses a field test study method with a six-blade spiral horizontal axis wind turbine (TASH) type. TASH performance is assessed by measured parameters such as rated voltage, generator output current and torque value; also non-dimensional parameters such as power coefficient, Cp, torque coefficient, Ct and Tip Speed Ratio, TSR values generated due to TASH rotation at every wind speed from 3.0 m/s to 4.5 m/s wind speed. Field test results obtained: Actual power (experimental) = 5.50 Watt and torque value = 10.7 N.m at a wind speed of 4.5 m/s. Cp = 0.0083, Ct = 1.2180, and TSR = 0.0068 at a wind speed of 3.0 m/sThe solidity value obtained based on the calculation results is 1.627 for a 5-blade wind turbine, while for a 6-blade and 8-blade wind turbine, the solidity values are 1.953 and 2,604. As the turbine solidity value increases, the power coefficient will also increase, inversely proportional to the torque coefficient, that as the turbine solidity value increases, the torque coefficient will decrease]]>

<![CDATA[The global market for Computer Numerical Control (CNC) milling machines continues to grow at a significant rate, with the automotive industry being the largest end-user. The Fanuc 31i controller is one of the leading controllers in the manufacturing industry. This controller has AI nano CNC features that support high-precision movements and high-speed NC program execution. The more understanding of the AICC (AI Contour Control) parameter settings can make a significant contribution to improvement of production efficiency and quality. This research is conducted to investigate the influence of changing the "R" value in the AICC parameter on the CNC Milling machine OKK VP1200 with the Fanuc 31i controller to machining time and workpiece accuracy. The experiments were conducted on three shapes: complex, circle, and square, using three test specimens with variations in AICC parameters ranging from R1 to R10. By adjusting these parameters, the actual machining time was recorded, and the accuracy of the machining process was measured using a Coordinate Measuring Machine (CMM) and later the data was analyzed. This study presents data and instructions for the application of AICC R1-R10 parameters that is adjusted to the specified tolerances or deviations. Furthermore, the research can provide the percentage of actual time compared to the programmed time if a CAM Programmer has determined the tolerance range limit or deviation of a product and determined which AICC parameters to use. In practice, a CAM Programmer can make predictions for two aspects based on the data in this research that are actual machining time and product accuracy.]]>

<![CDATA[One of the quality affected factors of machined products is surface roughness, which is affected by several factors, like force and vibration. Vibration is the derivation of deflection. To improve efficiency of double chuck, in this experiment will modify the holder of double chuck to decrease the vibration. The modifications are divided into used wood to decrease length force from clamp and change the entry angle from 45° to 90°. The vibration was measured by a vibrometer at the vertical axis. Each modification succeeded to decrease the vibration at a reduction of 1.5 mm, where the highest decrease was changed the entry angle from 0.21-0.23 m/s2 to 0.10 m/s2. Modification on changed the entry angle has better surface roughness which the value of 1.3 µm.]]>

<![CDATA[The lube oil cooler is one of the tools in the PLTGU lubrication system. The lube oil cooler functions to keep the lubricating oil temperature in the turbine at a normal temperature, namely ± 40 C. The temperature is maintained at normal temperatures to prevent damage to the bearings and overheating of the turbine. An overheated turbine will waste energy into heat energi. To maintain the temperature of the lube oil, a fin & tube type heat exchanger with crossflow flow was chosen. The design of the lube oil cooler begins by determining the initial design parameters for the cooling fluid and lubricating oil such as temperature, specific heat, mass flow rate, viscosity, density, and thermal conductivity. Furthermore, calculations are carried out using general equations and according to standards, simulation using Aspen Hysys V11 software and analyzing the design results. From calculaion we get dimentions of the lube oil cooler with an outside diameter 0,038 m, an inside diameter of 0,035 m, 18 BWG, a pipe length of 4,49 m, a number of 161 pipes, a number pipes per line 13 pieces with triangular shape and the number of pipes per row fins 2 pieces. The standard of lube oil cooler design is the value of pressure drop ≤ 0,68 bar, where the value of pressure drop on the duct side is 0,0075 bar and the tube side is 0.574 bar. For the simulation using aspen hysys V11, there is no error in the design as evidenced by the blue material flow and red energi flow. And the resulting effectiveness is 74.9 %.
