<![CDATA[Implementation of control systems has been carried out in many fields of science. One of it applications is in the agriculture fields. In this research we implemented a control system on farming in a box. Farming in a box is a system that uses old shipping containers for the purpose of growing plants in any environment. Inside shipping containers is fully assembled hydroponic pipe with air temperature control. In this research was built a little farming box from acryclic to imitate a shipping container. Main focus of this research is design an air temperature control using fuzzy logic controller. Fuzzy logic controller was choosen because many existing farming box use on off controller. In some application, fuzzy logic controller has better performance than on off controller. Farming box temperature is controlled by blowing cool air using an electric fan. In this case, cool air is produced by cold side of peltier. Electric fan speed is controlled by pulse width modulation signal (PWM) that generated from microcontroller. Air temperature data feedback is obtained from DHT 11 sensor that installed in a acrylic box. Sensor is physically connected with microcontroller and Fuzzy logic controller is embedded in microcontroller as an algorithm. Fuzzy logic controller was design with error temperature and error difference as an input, and duty cycle of PWM signal as output. Fuzzy logic controller system performs to reduce the temperature from 31,6 ° C to set poin 28° C in 71 seconds. Steady state error obtained by 1.28% and better than uncontrolled system that obtain steady state error 7,14%.]]>

<![CDATA[The 3 phase induction motor is a reliable and strong motor also has cheap price. However induction motor are also vulnerable, from the result of survey conducted by Electric Power Research Institute (EPRI), there are 41% cases of damage occur in the bearing caused by working environment condition, bearing age, and several other factors. Bearing fault is not easily to identified, with applying the data extraction method using the Discrete Wavelet Transform (DWT) and the K-Medoids clustering method will facilitate the identification process. The extraction method will pass the data in the form of current signals into the digital filter (Low Pass Filter and High Pass Filter) to be mapped into the region of frequency and time simultaneously, and clustering method will group data based on certain characteristics. Based on the clustering tests that have been done on the 3 phase induction motor current signal data with 3 bearing conditions, the Discrete Wavelet Transformation with mother wavelet bior1.1 decomposition level 2 and K-Medoids produce an accuracy rate of 86.8%.]]>

<![CDATA[Inception of electrical treeing can irreversibly deteriorate the insulation of polymeric power cables leading to a complete failure and initial process of degradation in polymer insulation due to a void that experiences high electric field stress in the material. This paper present will study filler’s influence on inception of electrical treeing growth in silicone rubber – oil palm endokaprium composite. The observed data is inception voltage and time phenomena in two types of test sample, that is " with filler " and " without filler ". Sample of filler consisted of silicone rubber and oil palm endokaprium composite for oil palm endokaprium weight is 0.1 grams and weight silicone rubber 3.9 gram. While the sample without filler is only silicone rubber . It is obtained that the tree inception voltages dan time for “with†dan “without filler†specimens are 8 kV / 182 seconds and 7,5 kV / 137 seconds, respectivelly.. It is considered that “fillerâ€Â acted as a barrier for tree inception. We throught that “filler†enhanced dielectric strength of silicone rubber and oil palm endokaprium by disturbing high electric field stress, result in higher tree inception voltage and longer tree inception time.]]>

<![CDATA[The availability of two types of solar panels that are common in the market namely monocrystalline and polycrystalline types cause confusion in the selection so that many solar panel users are questioning the differences of these two types of solar panel. This study produced a data logger system using Arduino Uno R3 to control voltage, current and temperature sensors for logging data that stores power measurement data from monocrystalline and polycrystalline solar panel in a micro SD. After it we can manage data to compare power produced between two types the solar panel. From the results of testing this data logger system it can be seen that monocrystalline solar panel are 9.18% better on power produced than polycrystalline when the maximum power conversion is generated.]]>

<![CDATA[Coffee roasting is the process of removing the water that is exist in the coffee beans. Roasted coffee beans will change weight and give a nice aroma and taste. The longer the coffee beans are roasted, the color of the coffee beans will continue getting darker blackish brown. The roasting level of coffee beans is determined from the change in color of coffee beans starting from light, medium and dark. Roasting coffee beans that develop on a home industry scale is still manual, that is, using more human labor in its operation. Therefore, this research will be made an automatic coffee roasting machine using a heater to heating the coffee beans, a DC motor to stir roasted coffee beans and a webcam to monitor changes in the color of coffee beans when roasted. Components of heating elements and motors controlled by Arduino Mega 2560 microcontroller while the webcam is connected with Raspberry Pi 3. As a component of performance that has been met with sensors as data collectors, microcontrollers as data processors and actuators as control systems. In this researh 3D modeling for a roasting container is done using SketchUp 3D design software. The results of the coffee roasting machine can meet the requirements of the system designed in accordance with the roasting level desired by the user and the thermocoupel give a better result in reading the temperature parameter compared to infrared thermometer. In 4,5 minutes the difference reading in temperature reach 27,50C between two sensors.]]>

<![CDATA[Purification water has several methods; one of them is the plasma generation. The circuit used to generate plasma is Zero Voltage Switching (ZVS), where its use uses the resonance circuit concept. The main category to generate plasma glow discharge is the circuit should generate high voltage output with a current range from 10-6 A to 1 A. In this study, when ZVS connected to the flyback converter with an input voltage of 12 V, the output values of 11 kV and 11 μA were obtained. In comparison, if ZVS was not connected to the flyback converter, the circuit is less stable, and the output value is weak because the output values only reach 8.97 kV and 8.97 μA. For maximum output, the ZVS circuit should be connected to the converter circuit due to the flyback converter can repair and strengthen the voltage. The flyback converter circuit is affected by the diode and capacitance effects. The effect of using capacitors in a flyback converter circuit is when the capacitance is too low, the ripple will form. Then when capacitance reaches a specific value, the ripple will decrease, and the voltage graph will approach a straight line. Hence the use of components in the ZVS and the flyback converter need to be considered because it affects how the release of plasma glow discharge will form.]]>

<![CDATA[Currently, renewable energy is under review so that its use can be more widespread in the future. One of the renewable energy sources that are commonly used is solar energy through solar cell technology that can convert solar energy into electrical energy and then becomes one of the components that makes up the solar power plant. The use of the solar power plant can be interconnected with distribution networks in electric power systems, both medium-voltage networks and low voltage networks. In this study, a 3 MWp capacity of solar power plant was conducted with the medium-voltage network system of X City. This interconnection study consisted of power flow and short circuit studies using ETAP 12.6.0 software. The results of the power flow study show the voltage level of each bus has increased by 0.293%-0.926% after interconnection with the solar power plant system, with a value that still matches the SPLN 1:1978 standard of 90% to 105%. Besides, the results of short circuit study show the value of the three-phase short circuit fault current experienced a change in value that is not too significant, with an increase of 1-37 A and a decrease of 1-5 A, with a value that is still according to the protection component rating standard of 25 kA.]]>
