<![CDATA[The orientation angle of a quadrotor UAV can be estimated from gyroscope and accelerometer data. Orientation can be predicted from gyroscope data under static or dynamic conditions, but the predicted value has accumulated errors. Meanwhile, orientation can also be calculated from accelerometer data, but only correct if the sensor is in a static state. To get a more precise orientation angle, the orientation predicted from the gyroscope data and the orientation calculated from the accelerometer data were fused using a Kalman filter. Determination of the condition of the sensor using a threshold value that is applied to the covariance of the acceleration data. in this study, the zero-acceleration compensation algorithm is used so that when the sensor is static, the orientation angle is calculated from the accelerometer. The use of this algorithm can increase the accuracy of the quadrotor orientation for roll angle to 96.84% and pitch angle to 98.91%.]]>

<![CDATA[Industry is one of the largest users of reactive power in the distribution of electric power. Industries use equipment such as induction motors, transformers and other equipment to support their production needs. Loads such as induction motors are inductive loads that require reactive power to operate. Reactive power in an electric power distribution network is a loss. Reactive power can reduce the effectiveness of the real power which is converted into active power so that the efficiency of real power usage is reduced. Installing a capacitor bank is one way to compensate for the use of reactive power in a load. Installing capacitor banks aims to improve the value of the power factor that has decreased due to the use of excessive reactive power loads. PLN has set a standard power factor value for consumers of 0.85 and reactive power consumption of 0.62 of the total power consumption. For this reason, it is necessary to carry out further analysis regarding the advantages and disadvantages of installing bank capacitors to improve the value of the power factor so that the ideal economic factor for consumers is obtained.]]>

<![CDATA[An Induction motor is an electric machine that converts electrical energy into kinetics energy and widely used in the industrial fields. Many disturbances that occur in the motor that cause production to be not optimal as for the problems that occur at PT. Madu Baru Yogyakarta is when there is a disturbance in the three-phase induction motor, workers still use manual methods to analyze the disturbance, so that the time used in the analysis takes a long time even the three-phase induction motor cannot work again. In overcoming this, it is necessary to implement a data logger system that can detect the electrical parameters of a three-phase induction motor in real time, in order to make it easier to analyze existing disturbances through graphs. The voltage sensor CYVS13-34U0 and current sensor SCT-019 will detect the electrical parameters which will then be processed by the Arduino Mega 2560 pro so that the processed data will be stored on the microsd card. The data resulting from the processing are electrical parameters in the form of voltage, current, apparent power, real power, reactive power, and power factor. The data will be saved as a file with .txt format which has an interval of about 1 minute for each storage.]]>

<![CDATA[The direction finder of a radio transmitter is a device that functions to find and determine the direction of a radio transmitter that works in the Ultra High Frequency (UHF) band. UHF frequency used is in the range of 420 - 440 MHz. The concept of Doppler radio is used as a method to determine the direction a radio transmitter is located. Radio Doppler use four receiving antennas which are installed at a certain distance so that it can produce a difference in frequency (Doppler) on each radio antenna because of the difference in the angle of the detected signal. The direction of the incoming signal will be displayed on a set of 16 LEDs and each LED will represent the direction of the incoming angle of 22.5 degrees. The detected frequencies are 422,580 MHz and 429,980 MHz originating from the UHF transmitter with 100mW of power and amplified with a radio frequency amplifier of 3 Watts power. The results show that the frequency of 429,980 MHz was detected with a maximum detectable distance of 1500 meters. The frequency of 422,580 can be detected with a maximum distance of 800 meters. This radio direction finder is can be used to find radio signal in UHF band frequency 420-440 MHz. The direction of the radio transmitter location is simply show in group of led’s as a direction detector. ]]>

<![CDATA[In planning the installation of solar panels at a location, it is necessary to have solar irradiance data at that location. Solar irradiance data is obtained through direct measurements using a solar irradiance meter. Solar irradiance measuring instruments usually use one of three types of sensors, including thermopile (pyranometer), solar cells, or photodiodes. Each has advantages and disadvantages. The advantages of solar cell sensors are that they have a faster response to sunlight, are more in line with the production of energy produced by solar panels and have a more economical price compared to other sensors. Solar irradiance is directly proportional to the short-circuit current of the solar cell. The aim of this research is to design an Arduino Uno-based device to measure the insolation and irradiance of sunlight, equipped with a data logger to support data analysis. The solar power meter is designed using a solar cell reference with a short circuit current of 455 mA. The microcontroller board used is Arduino UNO ATmega328 while the current sensor used is WCS2801 with a sensitivity of 2mA/mV. Irradiation, current and insolation data are recorded and stored every minute using a datalogger to SD card with a capacity of 16 GB. the average of % error when testing the comparison of readings with photodiode-based solar power meter is 1.747%. The highest point of sun insolation is 5.56.kWh/m2 during three-day period of data logging and it is achieved when solar cell is positioned horizontally on the terrace. ]]>

<![CDATA[The wind speed gauge in a wind tunnel plays an important role in the airflow simulation process so that it is similar to the actual conditions as desired. Wind speed measurement in wind tunnel mostly use manometer with special fluid (red manometer fluid) and the resulting data is in the form of analog data. The red manometer fluid is unavailable in Indonesia and its price is quite expensive so it becomes a challenge for wind tunnels that still use manometer. Therefore, it is necessary to make a new instrument for measuring wind speed that is easy to use by utilizing materials that are easily obtained but still apply the same measurement principles as a manometer in measuring wind speed in wind tunnels. The design of the wind speed measuring device can take advantage of microcontroller technology. The wind speed sensor design process goes through three stages including hardware design, software design, and system design. The hardware used for the system are an Arduino Uno R3 microcontroller, a differential pressure sensor MPXV7002DP, and an LCD. Research results obtain a wind speed sensor that can be used to measure wind speed in a low subsonic wind tunnel based on Bernoulli's principle that utilizes a pitot tube with a maximum speed of 30m/s. The wind speed sensor is an Arduino-based design that can display the wind speed measurement results on the LCD screen. The wind speed sensor was declared valid to be used to measure wind speed because there were no deviations from the wind speed measurement when compared to the measurement results from a calibrated anemometer.]]>
