Abstract

This paper discusses the design and simulation of the Cascade Greinacher circuit to increase the dc output voltage and current. The voltage increasing circuit using the Cockroft-Walton method has a large output voltage ripple and voltage drop. Meanwhile, half wave and full wave rectifier circuits are only capable of producing a DC output voltage and do not reach the maximum voltage value. In addition, the load resistance at each input power saturation is different and high frequencies require the addition of a capacitor circuit. Therefore, the Greinacher Doubler Circuit (GDC) rectifier is proposed with a modified diode and capacitor series arranged in nine levels in parallel. The circuit modification is used as a DC output voltage rectifier to reduce output voltage ripple. Then the circuit modification was tested by simulating the PSIM software and varying input voltages. Simulation testing uses a 220 volts voltage source, 50 Hz frequency, and component specifications for a single-phase step-down transformer 220 to 12 volts, 8 diodes (DXN, DN/DXN1, DN1/DXN2, DN2/DXN3, DN3), 8 capacitors with 4700Uf value (CXN, CN/CXN1, CN1/CXN2, CN2/CXN3, CN2), and 100 Ω resistor. simulation results which produce a voltage greater than 3 times the input voltage, namely 35.7 V and a current of 0.98 A. Even though at times 0.001 seconds and 0.0035 seconds and 0.0054 seconds the output voltage and current are constant at 4.9 volts respectively, the current is 0.03 A, current 0.08 A and current 0.013 A. The output voltage Vout, Vs and current continue to increase when it reaches 1 second.

Abstract

This paper discusses the design and monitoring system of ship leakage. Ship leakage causes accidents at sea. Therefore, a prototype design and monitoring system are proposed. The design uses fiberglass and resin with dimensions of 60x15x13 cm, and monitoring uses the Internet of Things to turn on three automatic pumps alternately. The results show that monitoring pump 1 obtained an average water volume of 0.00131 m3, time 83.92 seconds, discharge 0.0000157 m3/second, current 0.44 A and power 2.2 W. Pump 2 obtained an average water volume of 0.00161 m3, time 139.08 seconds, discharge 0.0000116 m3/second, current 0.24 A and power 1.2 W. While pump 3 obtained an average water volume of 0.00126 m3, time 52.26 seconds, discharge 0.0000241 m3/second, current 0.68 A and power 3.4 W. The monitoring results have different average water volume, time, discharge, current and power.

Abstract

This paper discusses the design of dual-axis solar tracker technology to measure the angle, torque and motor power of solar panels in dragon fruit fields in Banyuwangi Regency. The installation of solar panels that have been carried out in static conditions with the charging of solar panel energy produced is not optimal. Therefore, solar tracker technology is proposed to measure the angular velocity, motor torque, and motor power by following the direction of the sun. The dual-axis solar tracker uses a worm gear consisting of a spiral threaded shaft to drive a toothed wheel with a rotation angle of 180o. The results of the application of the solar tracker show that the angular velocity, torque and power increase significantly. Measurement of the dual-axis solar tracker with a time of 2-30 seconds obtained the angle, torque and power of the worm gear motor at a time of 0 seconds, namely -664.151 deg / s to a time of 30 seconds 621.534 deg / s. While the results of measurements with a time of 30-60 seconds produced an angular velocity of 621.534-2169.744 deg / s. Furthermore, the measurement of the worm gear motor torque at 0-30 seconds obtained 353,712-2286,268 Nm, and the measurement of the motor torque at 30-60 seconds produced a value of 2286,268-7356,913 Nm. The measurement of the worm gear motor power with a time of 2-30 seconds produced an average power of 7,785-46,984 kW, and the measurement of the motor power at 30-60 seconds produced a power of 46,984-101,479 kW.

Abstract

Sterilization rooms are a concern for patients in hospitals. Inpatients affected by infectious diseases require a special action room. Therefore, the application of the sterilization room control and monitoring system with IoT is proposed to overcome TB patients. The study technique covers the design and testing of the control system and IoT monitoring system with time variations of 60, 90, and 120 minutes. The results of the application of the control system application show that the time variation causes a decrease in current from 0.8A to 0.5A with a test time of 60 minutes, but inversely proportional to the voltage with a test time of 90 and 120 minutes, which increases by 3.2V-3.9V. While the results of monitoring data in the inpatient room have varying lag times ranging from 0.13 seconds, 0.8 seconds and 0.7 seconds. the average value of time variation and data transmission affects the decrease in the bacteria of the hospital room cleaning process. the longer the irradiation time, the number of bacteria will decrease. Sterilizer control and monitoring system is used as a recommendation for infectious diseases in the inpatient room in the hospital.
