<![CDATA[The conventional drying process for olive leaves is done in the sun. The drying capacity is relatively small over a long period. This process can be improved by using a rotary dryer. To determine optimal drying conditions in the temperature range of 30-45 [ºC], it is necessary to carry out numerical analysis using the Computational fluid dynamics method with varying heating temperatures of 30, 40, 50, and 60 [ºC]. The total heat energy transferred from the heater to the olive leaves by convection is 366,252 [kJ/s] and 21,371 [kJ/s] by conduction with a rotary dryer rotation speed of 75 [rpm]. The drying temperatures resulting from these four variations are 25.65, 26.85, 29.55, and 31.35 [ºC] with a heat flux of 2.542 x 10-6 [W/m2]. The heating temperature of the rotary dryer set at 60 [ºC] can distribute the heat of 1.8 [M.J.], resulting in an optimal olive leaf drying temperature of 31.35 [ºC].]]>

<![CDATA[Due to their affordability and compact size, the annual rise in fuel prices has prompted Indonesian consumers to opt for more fuel-efficient vehicles, particularly hatchback models. This study analyzes the key factors influencing fuel consumption in hatchback cars produced in 2024 in Indonesia using statistical analysis with MATLAB. The data analyzed includes technical specifications from various popular hatchback models in the Indonesian market, such as vehicle weight, torque, engine capacity, and engine technology. The analysis results show that vehicle weight has a moderate positive correlation (r = 0.25) with fuel consumption, meaning heavier cars use more fuel than lighter vehicles. In contrast, engine capacity and torque show weak negative correlations with fuel consumption, with correlation values of -0.13 and -0.18, respectively, suggesting that while these factors influence performance, their effect on fuel efficiency is relatively minimal. The findings highlight the critical importance of vehicle weight reduction as a key strategy for improving overall fuel efficiency. Furthermore, this study provides essential insights for consumers to select vehicles that offer a better fuel economy. It also offers valuable guidance for manufacturers looking to design more fuel-efficient and environmentally friendly cars. The potential for vehicle weight reduction to become a primary focus for increasing fuel efficiency in hatchback cars is especially emphasized, offering hope for a more sustainable automotive market in Indonesia]]>

<![CDATA[Batteries are one of the vital components that are the main source of energy in electric forklifts which of course must be considered, especially their performance in issuing voltage and density of electrolyte which can be influenced by other factors such as temperature. The design of the battery itself tends to be closed so that it has very minimal air circulation which makes the hot temperature trapped and affects the performance of the battery itself. For these problems, an analysis of the addition of an extra fan on the battery cover was carried out to determine the extent of the extra fan's influence on battery performance (temperature, voltage, and electrolyte density) with a lead acid on the electric pallet mover. SPSS (Statistical Package for the Social Science) is used as a research method which is expected to produce data that shows how much influence the addition of an extra fan has on the battery performance of the electric pallet mover. The results of this study show that the addition of an extra fan to the pallet mover battery cover provides a significant change in the temperature, voltage, and density of the battery electrolyte. When the level of the extra fan is in the off state (none) compared to the level of the extra fan in the high speed state (6500 RPM) in the temperature test, the results show that the average change is 10.93oC. Then when the level of the extra fan is in the off state (none) compared to the level of the extra fan in the high speed state (6500 RPM) in the Voltage test, the results show that the average change is 0.6 volts. Meanwhile, when the extra fan level is in the off state (none) compared to the extra fan level in the high speed state (6500 RPM) in the Density test, the results show that the average change is 0.22.]]>

<![CDATA[Water is an inexhaustible resource. In Indonesia there are several areas that have the potential of water energy for electricity production. Water energy can be used for electricity production and supports emission reduction programs because it does not produce CO2 emissions during the electricity production process by water turbines. One of the problems experienced by turbines is damage caused by cavitation. Cavitation itself is the formation of air gas bubbles due to very low pressure reaching below the vapor pressure, so that water evaporates at low pressure. This research was conducted to determine the effect of rotational speed on the potential for cavitation. This research was conducted using the CFD method and using the ANSYS application. In the simulation process, several variables are used, namely rotational speed and fluid velocity. The conclusion of this study is that the higher the rotating speed of a propeller turbine, the higher the cavitation potential that will occur in the propeller turbine. Because the higher the rotational speed of a turbine,so the lower the pressure that occurs in the turbine, this is in accordance with Bernoulli's Law. Suggestions for further research can be done with several modifications or variations of the winglet radius so as to get a better design. In addition, in future research it is also possible to modify the angle of the blade so as to reduce the emergence or formation of gas bubbles on the propeller blades due to decreased pressure.]]>

<![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.]]>
