Oil palm (Elaeis guineensis Jacq.) is one of the commodities that is expected to increase the economic income of the community, especially plantation farmers. The palm oil industry in Bangka district in 2020 is 41.88 thousand tons. The production process of crude palm oil produces waste that has the potential to pollute the environment, namely solid waste and liquid waste. Palm oil mill effluent (POME) contains methane gas (CH4) which has the potential to be a source of energy that can be processed into biogas and solid waste in the form of shells, fiber, EFB has the potential to become biomass. The results obtained from the calculation of the total power that can be generated for 2.5 years of liquid waste (POME) is 6.9462 MW in the category of high heat waste, followed by solid waste (TKS) of 1.4881 MW, fiber waste of 0.9864 MW and shell waste of 0.5646 MW. The total CO2 emissions generated from the generator for 2.5 years for solid waste are 73893.63 tons of CO2 in the category of high-heat waste, and for liquid waste, it is 65867.09 tons of CO2.

This study proposes a hybrid method to classify and estimate the location of short circuit disturbance on power transmission lines. The hybrid method uses Discrete Wavelet Transform (DWT) and Adaptive Neuro-Fuzzy Inference System (ANFIS). The transmission system is implemented in a real system, in which the electric power transmission system on the KP bus to the GS bus is with a length of 64 Km. The DWT is used to process information from each phase voltage and current transient signal as well as the zero-sequence current for one cycle after the disturbance has started. The ANFIS classification is designed to detect disturbance on each phase and ground in determining the type of short circuit disturbance. ANFIS estimation is used to measure the location of disturbance that occur on the transmission line. The training and testing data are generated by simulating the types of short circuit disturbance using software with variations in disturbance location and fault resistance. The result is that the disturbance classification is with 100% accuracy and the estimated disturbance location is with the lowest error of 0.0006% and the highest error is 0.03%.

This paper presents the sliding gate opener system that android smartphones can remotely control using Bluetooth protocols. The gate opener is driven by a 12-pole single-phase induction motor of permanent-split-capacitor type (PSC motor) coupled with a worm gearbox and rack-pinion power transmission. The PSC motor installation is wired to rotate either forward or in the reverse direction by using a contactors arrangement controlled by the Arduino microcontroller module. Two limit switches are installed at the ends of the gate opener movement to inform the microcontroller to stop the motor automatically when the gate opener touches them. Moreover, the microcontroller module has been wired with Bluetooth transceiver HC-06 enabling it to communicate with other Bluetooth devices. The microcontroller module has been programmed so that the gate opener movement can be remotely governed from android smartphones and controlled at the site by operating a set of pushbutton switches mounted onto the control panel's door. The functional test has been conducted on the sliding gate opener system, and the result shows that the gate opener movement can successfully be controlled locally through operating pushbutton switches and remotely using an android smartphone with up to 8 meters.

Eria Hospital has implemented a fingerprint attendance system, but it has some limitations such as difficulty in reading fingerprints, limited access to fingerprint scanner which is only located in one place, and dependence on shared equipment. To overcome these problems, an Android-based attendance application was developed using Waterfall software design. This application uses QR code and GPS to make it easier for employees to record their attendance while in the work area. The quality of this application is based on ISO 25010 quality standards, which include functional testing with all functionalities working well, reliability testing with an A rating, compatibility testing with split-screen feature compatibility, security testing with an A rating, portability testing with results can be install on different devices and Android versions 8.1 to 12, maintainability testing with an A rating, efficiency testing with a startup time of around 1.6 seconds, and user experience testing with attractiveness score of 2.62, perspicuity score of 2.57, efficiency score of 2.62, dependability score of 2.51, stimulation score of 2.62, and novelty score of 2.40. Overall, the implementation of an Android-based attendance application using QR Code has proved to be a viable solution to the challenges faced by the fingerprint attendance system, and has contributed to the optimization of attendance data collection and processing in Eria Hospital.

Variable refrigerant flow type is a multi-split type air conditioner for multi-story buildings. The aim of this study getting obtains optimization placement of the condensing unit to inlet air temperature in a multi-story building using the CFD method. The simulation was conducted from the 11th to the 30th floor. There are three variations of condensing unit position on each floor (Variation 1), on every two floors (Variation 2), and on the roof (variation 3). The result of the first variation is 35.32 °C, with the difference between the highest and lowest is 3.9 °C. The average temperature of the 2nd variation is 34.44 °C, with the difference between the highest and lowest being 0.92 °C. The average temperature of the 3rd variation is 36.65 °C, with the difference between the highest and lowest being 8.03 °C. Among the three variations, the 2nd variation of the condensing unit input air temperature is lower. Then the difference between the highest and lowest temperatures is not too far apart, indicating a more even distribution of air. The 1st, 2nd, and 3rd variations condensing unit position do not exceed Panasonic VRF air conditioner operational temperature limit, which is 52 °C.

To determine the aircraft’s flight performance, the airfoil type must be considered when designing the wing. A vortex can form when the airfoil travels through a fluid stream with a difference in velocity and pressure around it. Airfoil modification is carried out to delay the occurrence of flow separation by adding a vortex generator. This paper discusses how adding the vortex generator helps slow the stall’s onset and how the vortex generator affects the fluid flow and aerodynamic forces acting on the NACA 632-415. The vortex generator profile is positioned at an x/c = 20% of the chord line’s direction from the leading edge. The variation used is an airfoil’s angle of attack (α). Some parameters to be evaluated include the coefficient lift force (CL), the coefficient drag force (CD), and the gliding ratio (CL/CD). The research was conducted by the CFD method based on the angle of attack that produces the coefficient lift and drag forces. The addition of the vortex generator can delay the flow separation, increase the lift force coefficient by about 24.9%, the drag force coefficient by about 2.7%, and the gliding ratio by 9.1%.
