Abstract
This study aims to mitigate harmonics in a Single Phase Inverter in the design of inverter products with harmonics filters which can later be used as a basis for consideration of the quality of electricity on the harmonics side for the use of AC load power with power plants sourced from DC generators using an inverter. An experimental electrical circuit was configured by giving nonlinear loads effect to determine the number of harmonics that appear. Then design filters on the circuit to mitigate the harmonics that occur in accordance with IEEE 1531-2003 standard.

Authors: Sekarsari K , Tata T 
Published: March 2021

Abstract
This research presents an overview of the performance of the PID control technique applied to the Brushless DC motor to regulate the speed using the Arduino microcontroller and LabView software. Brushless DC motors are chosen because they have high efficiency both in performance and longer durability. Kp, Ti and Td parameter tuning techniques use the Trial and error method and the results obtained from the value of Kp = 0.050, Ti = 0.001 and Td = 0.001 indicate a minimum error compared to controls without using PID. The percentage of overshoot still exists but the rise time and settling time indicate a faster response speed to the setpoint.

Abstract
The prototype of the rice drying machine is a device used for rice dryers that are not weather dependent. The driver of this prototype rice drying machine uses ½ HP induction motor as its main mover. To be able to adjust the rotation of the induction motor using Variable Frequency Drive (VFD) brand LS iC5 with 1 HP power. The rotation needed to rotate the load can be done by changing the frequency and voltage so that the rotation speed of the induction motor can be adjusted as needed. From the testing of a no-load induction motor with a frequency adjustment range from 5 Hz to 13 Hz, the induction motor speed is 142.8 rpm (rotation per minute) to 375.3 rpm. The measured voltage is 76.5 V to 116.7 V and the measured current is 2.5 A to 1.6 A. From the results of the test of a no-load induction motor it can be concluded that the ratio of frequency to voltage is directly proportional while the ratio of frequency to current is inversely proportional. In testing induction motors with a frequency adjustment range from 5 Hz to 9 Hz, they produce the same conclusions as to the induction motor load testing. VFD is certainly appropriate to be used as a speed regulator as needed.

Published: March 2021

Abstract
This study aims to determine the effect of the installation of Distributed Generation (DG) on the value of voltage drop and real power losses in the distribution network of 20 kV Gunung Dukuh feeder (GNDH). In addition, this study also aims to determine the optimal distribution location of Distributed Generation (DG) to get the best voltage drop and power losses. The background of this research is that the voltage drops and power losses are common in GNDH feeders at PT. PLN (Persero) Cimahi area. The voltage value on the GNDH feeder is sometimes still below the standards set by PLN. This will certainly cause the load not to work optimally and can even cause damage to the electricity load and in the end will be very detrimental to all parties, both the electricity consumer and PT. PLN (Persero). Based on the characteristics of DG directly connected to the distribution system, there is no need for a transmission system to deliver electricity. This is certainly very influential on the decrease in the voltage drop and the value of power losses. The method used in this research is power flow simulation using ETAP 16.0.0 software and analysis after getting simulation results. The findings of this study are the simulation results prove that the installation of DG affects the decrease in voltage drop and power losses in GNDH feeder, before installation of DG the voltage drop in GNDH is 10.1% and the value of power losses before DG installation is amounted to 446.5 kW. After the DG installation simulation, the optimal installation of two DGs is found on the TM 36 bus and the TM 42 bus with a decrease in the voltage drop to 1.18% and a power loss value to 117.2 kW.

Published: March 2021

Abstract
The photovoltaic generator is a renewable energy generator and this generator can be used as a DG because it is an environmentally friendly generator and can be stored close to the load because it does not cause pollution to consumers who are near the plant. Photovoltaic generator requires an inverter to convert the voltage generated by PV (DC voltage) to the voltage needed by the grid (AC voltage). In this study, the data obtained is the planning of DG installation in Karimunjawa. However, there is no harmonics calculation in the network. So that requires the design of an inverter in order to analyses the harmonic generated and the effect of harmonics on the grid. Not only inverters, this generator also needs a boost converter because the voltage generated by PV is insufficient to convert into a 400 Volt AC voltage. The inverter will use the PWM technique which will convert the DC voltage to AC and use an LC filter to refine and reduce the harmonic generated by the inverter. Simulation in this research is to found value of the component in LC filter and Boost Converter. After that the circuit will connect to the grid for analysis harmonic on the load.

Published: March 2021

Abstract
Mercury has a significant negative effect on the health of humans and living things, and is a dangerous element that is widely known. Mercury is commonly found in gold mining wastewater. One way to remove mercury from waste water is to use the adsorption process. One of the adsorbents used in the absorption of mercury is palm shell fly ash. Palm shell fly ash is solid waste from the result of burning palm shells on the boiler. The use of fly ash from palm shells as an adsorbent is preferred because it is cheap, environmentally friendly and available in large quantities. The adsorption process is carried out by contacting the adsorbent directly with waste water. Addition of adsorbents to wastewater can increase the pH of wastewater to 4 levels. The best adsorption results are indicated by the efficiency of mercury ion absorption up to 100%. The adsorption capacity of the adsorbent increases with increasing time of stirring the adsorbent in wastewater.
