PLN (Persero) ULP SIDAREJA <p style="text-align: justify;"><em>Increasing consumers of electrical energy impacts increasing the risk of disruption that distribution systems can expose to consumers. In order not to interfere with the distribution of electrical energy, the protection system installed in the electrical energy distribution network must work optimally. Coordination between protections installed in the distribution network has a significant impact on the quality of distribution. Therefore, the protection components, that is, the reclosing switch, the overcurrent relay (OCR), and the ground fault relay (GFR) must be configured correctly. Proper adjustment is where the protection system works according to its capacity, so the effects of disturbances can be minimized, the disturbances are not widespread and can lead to power outages. The grid protection system from the Lomanis –05 feeder line to ULPSidareja is already good because the components of the protection system are well matched. Since the components do not comply with SPLN 64: 1985 and IEC 60255, that is, 0.35 to 0.4 seconds, we can conclude that the quality of coordination between protection systems is good, but we still evaluate the applied settings. is needed. Not compliant with SPLN 64: 1985, but compliant with IEC60255.</em></p> Riki Andriyan, Nasrulloh Nasrulloh, Randi Adzin Murdiantoro Copyright (c) 2022 Journal of Electronic and Electrical Power Applications Thu, 19 May 2022 00:00:00 +0800 THE ANALYSIS OF THE EFFECT OF RAINFALL AND LOAD IMBALANCE TOWARD AN ELECTRICAL POWER LOSS AT PT. PLN (PERSERO) ULP BUMIAYU. <p style="text-align: justify;"><em>Electrical energy is a very essential energy where almost all human needs are related to it. The distribution of electricity in both of transmission and distribution networks are expected to operate optimally and continuously. The constraints in the distribution of electrical energy are usually caused by several factors, including rainfall and load imbalances. The data on the value of rainfall and load imbalance will later be analyzed with the value of electrical power loss. This study aims to determine whether rainfall and load imbalance affect the electrical power loss. By knowing the value of these constraints, it will be analyzed with the value of electrical power loss. The type of research used is quantitative analysis research using multiple linear regression test.. Based on the results of linear regression analysis in the summary model, ANOVA, the coefficient showed a rainfall significance value of less than 0.05, it meant that there was no significant effect on electrical power loss and a load imbalance significance value of more than 0.05, mit showed that there was a significant effect on power loss electricity. Meanwhile, the percentage of influence of the independent variable of rainfall and load imbalance on the dependent variable of power loss was 9,4% and the remaining 90,6% was influenced by other variables not examined.</em></p> Yogi Ade Putra, Rizki Noor Prasetyono, Randi Adzin Murdiantoro Copyright (c) 2022 Journal of Electronic and Electrical Power Applications Mon, 30 May 2022 00:00:00 +0800 LIGHT CONTROL SYSTEM WITH INTERNET OF THINGS (IOT) AND BLUETOOTH TECHNOLOGY USING NODE MCU <p style="text-align: justify;"><em>Controlling lights at home can actually be done manually, but with the development of technology in the modern era, there are many ways to control lights, for example remotely using IoT technology, using bluetooth and can also use remote controls. This study aims to create a modern light control system with internet of things and Bluetooth media. The NodeMCU microcontroller was chosen as the brain of the control system, because there is already a module that can be connected to the internet. The input of the control system uses the HC-05 bluetooth module, while for the output it uses the relay module. After testing both software and hardware, the result is that the response speed after sending data from the two media has different vulnerabilities, IoT media has a response that depends on the internet network used with an average of 1.38 seconds turning on the lights and turning off the lights 1, 61 seconds, while with bluetooth media has a very good response, namely to turn on the lights 0.18 seconds and turn off the lights 0.24 seconds. This control system cannot use both media simultaneously and when it is first turned on the system must be connected to the internet first so that bluetooth media can be run or used.</em></p> Aldi Burhannudin, Isra' Nuur Darmawan, Priyono Yulianto, Eko Sudaryanto Copyright (c) 2022 Journal of Electronic and Electrical Power Applications Mon, 30 May 2022 00:00:00 +0800 ANALYSIS OF THE EFFECT OF MAGNETIC LOCATION AND ADDITION OF BERRIER FLUX ON BACK EMF VALUE ON PMSG 12S8P USING FEM METHOD <p style="text-align: justify;"><em>The purpose of the study was to determine the effect of variations in the placement of magnets and flux barriers on the back emf value in the 12S8P permanent magnet synchronous generator (PMSG) modeling. Process the output voltage (back emf) by varying the geometry of the magnet's location and adding a carrier flux to each variation of the magnet's geometry because magnets are one of the most important parts of the Permanent Magnet Synchronous Generator (PMSG). Where in this study there are 2 independent variables, namely the location of the magnet and the addition of a carrier flux. Where variations in the location of the magnet there are three variations, namely on the surface of the rotor, 2 mm below the surface of the rotor, and 4 mm below the surface of the rotor and each variation will be added with a flux barrier. While the dependent variable in this study is the back emf value. The data analysis technique used is a simple linear regression method, where the simulation results are then entered into MS.Excel and then processed using SPSS software. From the results of the study, it was concluded that the location of the magnet and the addition of a carrier flux could affect the Back EMF value, as indicated by the significance of the regression analysis of the dependent and independent variables 0.001 &lt;0.05. From the Back EMF value data, the closer the magnet is to the stator or rotor surface, the greater the back EMF value, on the contrary, the farther the magnet is from the stator or rotor surface, the smaller the back emf value.</em></p> Nur Cholis, Rizki Noor Prasetyono Copyright (c) 2022 Journal of Electronic and Electrical Power Applications Mon, 30 May 2022 00:00:00 +0800 IMPLEMENTATION OF MOTORCYCLE SECURITY EQUIPMENT USING RFID BASED ARDUINO UNO E-KTP <p style="text-align: justify;"><em>During a pandemic like now, many workers are being expelled by the company, resulting in a decline in the economy in various regions. To meet the needs of a person may do bad things such as curanmor (motorcycle theft). Even though the motorbike is equipped with a fairly strict security system, it is still sometimes broken by thieves. This study aims to create a motor vehicle security system based on Arduino R3 and RFID as an e-KTP sensor. Where this system can turn on or turn off the motorbike using an ID card or using its RFID Pin. even though the thief managed to break into the ignition, the motor still couldn't start because it needed other access. Based on the results of observations and tests carried out, the authors can conclude that the performance of the motorcycle safety device system using e-KTP works quite well. When the contact is on, it will activate the safety device system before activating the motor electrical system. RFID needs access to the appropriate e-KTP and is forwarded to the microcontroller (Arduino) then produces output to the relay to turn on the motor's electricity so that the motor can be turned on/started</em></p> Ahdika Dafiq Mafaja Yoni, Nasrulloh Nasrulloh, Edmund Ucok Armin Copyright (c) 2022 Journal of Electronic and Electrical Power Applications Mon, 30 May 2022 00:00:00 +0800 MODELING THE CONTROL PANEL CIRCUIT FOR NICE 3000 ELEVATOR 5 FLOORS USING ELECTRICAL CONTROL TECHNIQUES SIMULATOR SOFTWARE <p style="text-align: justify;">Elevator or is one of the tools that serves to facilitate human activities whose routines are more often in a storied room. The existence of this elevator is a substitute for the function of the stairs in reaching each subsequent floor in a multi-storey building. This study simulates a 5-floor elevator control circuit using electrical control techniques simulator software. The use of this application is very helpful for simulating control circuits before the equipment is installed and assembled. Useful for minimizing failures and troubleshooting of the circuit. Based on the results and discussion of the research, there are three main circuits in the control circuit, the new contact circuit and the power circuit. The connection of the power circuit to the motor between the UP contactor and DOWN contactor is not the same. UP contactor connection and motor (R and U), ( V and T ), (T and W). While DOWN contactor and motor (T and U), (V and R), (R and W). This circuit is commonly called an interlock circuit in which the two auxiliary contacts are locked between the auxiliary contact (R. NC) and the auxiliary contact (F.NC) which ensures that they cannot work simultaneously. The process of the elevator going up (UP) has been successful and shows a simulation of the lit going up and without any errors. And the elevator down (DOWN) process has been successful and shows the simulation of the lit going up and up without any errors</p> Mohammad Zidan Alfariki, Rizky Mubarok Copyright (c) 2022 Journal of Electronic and Electrical Power Applications Mon, 30 May 2022 00:00:00 +0800
