<![CDATA[Microorganisms such as Escherichia coli in water are a component that is difficult to remove in conventional water treatment systems. Several systems have been implemented to reduce levels of microorganisms is the use of disinfectants, the membrane filtration and activated carbon absorption. These systems have several weaknesses, so that not all microorganisms can be removed from drinking water. The plasma system is an applicable technology for removing organic compounds and microorganisms in drinking water. By creating plasma in water will produce several of active species such as OH-, H+, O3 and H2O2 that has a high oxidation potential, decompose organic compounds and kill microorganisms in the water significantly. This paper will describe the removal of microorganisms in drinking water using a plasma system by the method of dielectric barrier discharge (DBD ). The results howed that the pH of drinking water produced in the range 6.5 to 7.3. The higher voltage causes the higher the conductivity, temperature and ORP water. Removal efficiency for the content of microorganisms Coli Fecal and Coliform in the range 99.2 to 100% after water was injected voltage of 13-17 kV for 10 minutes.]]>

<![CDATA[The uncrewed Aerial Vehicle (UAV) operation is currently dominated by autonomous technology (autopilot) rather than manual control via remote control. During flying the mission autonomously, communication between the UAV and the Ground Control Station (GCS) must be in good and stable conditions. The GCS can well receive the telemetry data and payload sensor data carried by the vehicle. Conversely, any inconsistency parameters can be corrected by the GCS before transmitted to the UAV. Therefore, the role of the antenna is crucial to avoid signal loss during the communication process. This study focuses on GCS’s antenna. By designing the Yagi type antenna with the optimization of the distance, the number of directors, material, and shape of the reflector through CST simulation. The best option chosen is the Yagi antenna with the same distance between directors, seven directors, copper material, and flat reflectors with a VSWR of 1.1134, return loss -25.411 dB and 10.7 dB of gain. The measurement result after fabrication is the VSWR of 2.165 and the return loss of -8.677 dB. The antenna test results, when the UAV was flown as far as 2.5 km, found that the signal strength received by the GCS is -70.68 dBm with RSSI 107, and the signal strength in percent is 96%. ]]>

<![CDATA[The growth of type-2 fuzzy logic system is penetrating electric power system field, especially on electric power system control sub-field in order to simplify the design of power system stabilizer (PSS). Traditionally, the function of conventional PSS is to damp rotor oscillation when a disturbance occurred due to transmission configuration or/and loading changes. However, the response of conventional PSS is slow with long settling time and high peak overshoot. To cover this problem, PSS based on type-2 fuzzy logic system (PFT2) is proposed. Simulation results show that the PFT2 is able to improve the stability of a single machine with 3 scenarios on transmission configuration and loading variation. The PFT2 gives shorter settling time for all scenarios and loading variation than the settling time of conventional PSS. Also, the peak overshoot of the PFT2 is smaller than the peak overshoot of the other competing PSS.]]>

<![CDATA[Besides the ingredient composition, another important thing in the process of making dough is proofing, ie. dough rising process prior to roasting process. Proofing process requires a stable temperature to ensure that the dough is well rising. The purpose of this research is to make a proofing machine that uses DHT11 as a temperature sensor. Proportional-Integral-Derivative (PID) controller is implemented to guarantee that the machine remains at the temperature of 350Celcius, in which the fermentation process would success. PID control has been implemented in fluorescent lamp which been set its dim light to generate heat until it reach a predetermined set point value. The temperature was monitored using LCD and set to remain stable with the help of fan. The proofing process will last for 15 minutes which ended by the sound of the buzzer. The testing result shows that the value of , , will reach set point value within 120 seconds.]]>

<![CDATA[Human nail disease is usually ignored since it does not reveal clinical signs that are harmful to one's health. Nail disease, on the other hand, can be an early sign of a health issue. Some types of nail disease can cause infection, injury, or even the loss of the nail itself. It can reduce a person's aesthetics and beauty. Nail disease is very varied, so it is often difficult for clinicians to diagnose because several types have high similarities. Therefore, an automatic nail disease classification method based on nail photos was proposed in this study. The proposed method was based on the VGG-16 neural network architecture with an Adam optimizer. Nail diseases including Koilonychia, Beaus Lines, Leukonychia have been classified in this study. The model in this study is simulated in Python programming. The simulation results show that the highest classification accuracy is 96%, achieved with epoch-10. The transfer learning method based on a neural network simulated in this study is expected to support the clinical diagnosis of nail disease.]]>

<![CDATA[Wireless Fidelity (Wi-Fi) is the modern telecommunication technology nowadays being so widely used and developed at operating frequency of 2.4 GHz, that needs microstrip antenna as best suited supporting means for transmitting and receiving data signals as well at its wave transceiver subsystem. The proposed antenna design were consists of four elements rectangular patch antenna with peripheral slits technique arranged in a linear array of 2x2 operating at the frequency of 2.4 GHz until 2.5 GHz. In addition to that, the feeding technique used in this research is microstrip fed line. The simulation from this research resulted in reducing the size of related antenna dimension up to 17% compared to that of four elements array without peripheral slits. It is also apparent that the bandwidth of the proposed antenna is 320 MHz (2.253 GHz–2.573 GHz) which is equivalent to bandwidth increase percentage of 13.07%, The simulation results in the center of frequency 2.448 GHz obtained return loss of -26.14 dB with a VSWR of 1.104. The measurement results obtained bandwidth of the proposed antenna is 150 MHz (2.424 GHz–2.574 GHz) which is equivalent to 12% increase of bandwidth percentage. The results of measurements process at the center of frequency 2.448 GHz obtained value of return loss of -16.88 dB with VSWR of 1.304.]]>

<![CDATA[The battery balancing method is commonly used in cell circuits and battery circuits to maintain the power continuity on the DC Bus. The power continuity on the DC Bus is guaranteed if the load continues to get a power source, even if either the battery or power supply malfunctions. Besides, the battery balancing method is also used to protect the battery from excessive charging current pliers flowing into the battery. Therefore, the State-of-Charge (SoC) should be concern in balancing the maintained battery condition on both systems and avoiding overcharging. Artificial Neural Network (ANN) is used in this paper to determine the value of battery SoC. Based on simulations using MATLAB 2018, SoC values with ANN showed accurate results with error values below 0.1%. Based on the simulation results, the two batteries, which are arranged to have a difference of SoC value of 0.3%, will achieve a balanced SoC value for 28.45 seconds from the simulation.]]>

<![CDATA[Substrate integrated waveguide (SIW) is a technique to implement waveguide into microstrip material that can be applied to filter, antenna, mixer, coupler, and so on. Implementation of SIW to filter can overcome the problem of size reduction and high insertion loss commonly used in a conventional filter. While the complementary split ring resonator (CSRR) method overcomes the problem of size reduction and selectivity in conventional filters, thus combining the two can provide better filter performance. This research proposes both methods in realizing a bandpass filter by using a parameter study. Bandpass filter design works on a frequency of 3.4 – 4.6 GHz with an insertion loss value of 0.5 dB and a return loss value above 15 dB and has one transmission zeros at the frequency of 3.32 GHz. While the measurement results provide an insertion loss value below 3 dB and 6.5 dB return loss.]]>
