To ensure that the performance of the protection system is still good or not in terms of protection, calculations and adjustments must be made to the safety relay settings, especially the over current relay. In the research, analysis of the over current relay protection settings on the 30 MW generator at the Poso 1 PT PLTA unit. Poso Energy obtained that the maximum load current data on the generator was 2042 A, while the calculation results obtained were 2041.7 A. For the relay (top) operating time in the specification data, the value was 1.4 s, while in the calculation results it was 1.3 s. And for the setting current (Is) in the specification data the value is 4.7 A, whereas in the calculation results it is 4.28 A. Over current relay (OCR) or over current relay is an auxiliary relay from the differential relay, the over current relay is used to secure the generator of the overcurrent in the Poso 1 PLTA is PCS-985GE-EN-H2-110V-5A. In the specification data, the TMS value is 0.15 s, while in the calculation results it is 0.14 s. This means that data in the field is slower to protect components from interference by 0.01 s. However, overall the overcurrent relay settings on the generator at the Poso 1 PLTA are still in good condition.

Sign language is a form of language that can be learned which prioritizes communication with body language, facial expressions, and some non-sounds. This sign language is widely used by the deaf and mute. However, there is still a lack of institutions teaching sign language, books on sign language, and a tool for learning sign language. This study aims to design a hardware system that can translate sign language and output in the form of audio and display on the LCD. The stages of the research included designing the physical form of the device, testing the sensor flex, testing the MPU6050, testing the Nrf24l01, testing the Dfplayer, testing the Liquid Crystal Display (LCD), and testing the overall device on the A-Z alphabet. The results showed that when the Flex sensor was not indented the average error was 1.23%, and when it was indented the average error was 2.01%. The delay time required in sending data using Nrf24l01 media for conditions without obstructions is 0 seconds with a distance of 1 meter, with a barrier of 9.84 seconds with a distance of 3 meters, at a distance of 3 meters the data cannot be sent.

A solar tracker is a photovoltaic (PV) system support tool aimed at optimizing solar energy absorption by directing solar cells to follow the movement of the sun.In this research, a solar tracker for PV with battery load model was created using MATLAB-Simulink with each controller, namely Proportional Integral (PI), Proportional Derivative (PD) and Proportional Integral Derivative (PID) and the simulation results were compared. The simulation results show that the PID controller is the controller with the most optimal results because all set point values entered in the output remain the same and the overshoot value is also low, the PD controller is the controller that produces high errors and also overshot reaching 120 V, and the PI controller is the controller that the results are closest to a PID controller where the resulting overshoot value is only around 20%.

Robotic arms are a type of robot that is currently developing rapidly in industry, this has caused robotics technology to become one of the mandatory subjects taught in universities. In the Undergraduate Department of Electrical Engineering, Faculty of Engineering, Tadulako University, the robotics course is a mandatory subject studied by students, especially students who take the weak current concentration (TEN). This research aims to provide students with an understanding of how to control a robot arm. The design of a robot arm system with 4 degrees of freedom is made using several types of control such as control using Arduino IDE software, push buttons and potentiometers. The results of testing the robot arm trainer after controlling it with three types of control were successful. In the first control using the Arduino IDE software control it shows that the direction of rotation of the motor rotates according to the program target given, in the second control using a push button it shows that the speed and acceleration are directly proportional to changes in motor degrees, then in the third control using a potentiometer it shows that the degree mapping on the potentiometer is directly proportional to the degree of the stepper motor. However, in the test there were differences in degree values when the motor rotated which caused the resulting data to be inaccurate. This is due to a mismatch in tooth size between the belt and the stepper motor gear, causing wear on the belt.
机械臂是一种机器人，目前在工业领域发展迅速，这使得机器人技术成为大学的必修课之一。在塔杜拉克大学工程学院电气工程本科系，机器人课程是学生必修的一门课程，尤其是选修弱电专业（TEN）的学生。本研究旨在让学生了解如何控制机械臂。通过使用 Arduino IDE 软件、按钮和电位计等多种控制方式，设计了一个具有 4 个自由度的机械臂系统。在使用三种控制方式对机械臂训练器进行控制后，测试结果非常成功。在第一种使用 Arduino IDE 软件控制的情况下，电机的旋转方向与所给的程序目标一致；在第二种使用按钮控制的情况下，速度和加速度与电机的度数变化成正比；在第三种使用电位器控制的情况下，电位器上的度数映射与步进电机的度数成正比。然而，在测试中，电机旋转时的度数值存在差异，导致得出的数据不准确。这是由于皮带和步进电机齿轮之间的齿尺寸不匹配，导致皮带磨损。

By using the float magnetic level gauge method which consists of a reed switch as the main component to take height level readings. The neodymium magnet used in the buoy functions as a trigger to activate the reed switch when the buoy height reaches a certain level. The use of the voltage divider principle is to obtain variations in the sensor output voltage which is then converted into water level readings. The process of monitoring waste liquid levels uses LabVIEW software. Research has been tested in one of the departments in the metal processing industrial area which obtained the results that the sensor readings correctly provide an output signal to the microcontroller which functions as a relay controller which activates the drain pump motor when it reaches full level. With a monitoring system, users can control the system via computer without having to go directly to the field to activate the pump motor manually

The need for the use of electric power in modern times has experienced many developments in the field of technology, which of course has an effect on the amount of electricity consumed in society. Along with the rapid demand for electricity in Indonesia. The reliability of the electric power system is key to meeting the community's needs for electrical energy. This is due to the increasing number of human activities that require electrical energy. This study aims to analyze the reliability of protection coordination, working principles, security, and SBEF relay simulation when a fault occurs at the Maros substation. The method of data collection and direct observation in the field was carried out precisely at the Maros 150 kV Substation, the Maros Transmission and Substation Service Unit (ULTG). The results of the study, namely the reliability of the SBEF relay protection coordination when a fault occurs at the Maros substation, show that the first relay to work is the OCR GFR on the feeder side because, based on the working current settings and working time, if given a fault current of 3021 A, it will work after 426 ms, followed by the incoming side GFR OCR relay, SBEF stage 1 Fault percentage = 0075% so that it has a reliability percentage of 100%. The working principle and safeguards carried out on the SBEF relay when a fault occurs at the Maros substation and the data recap of the Maros ULTG fault can be seen by comparing the frequency of faults that cause the transformer to go out before and after the implementation of the two-stage SBEF relay function and the frequency of faults that cause the transformer to go out at ULTG Maros in 2019 as many as 1times and in 2020 as many as 0 times. The simulation on SBEF when a fault occurs at the Maros substation on the transformer uses the ETAP 19.0.1 application; the first time it works is GFR.
现代社会对电力的需求在技术领域经历了许多发展，这当然会对社会用电量产生影响。随着印度尼西亚对电力需求的快速增长。电力系统的可靠性是满足社会对电能需求的关键。这是因为需要电能的人类活动越来越多。本研究旨在分析马罗斯变电站发生故障时保护协调、工作原理、安全性和 SBEF 继电器模拟的可靠性。数据收集和现场直接观察的方法正是在马洛斯 150 千伏变电站、马洛斯输变电服务单元（ULTG）进行的。研究结果（即马洛斯变电站发生故障时 SBEF 继电保护协调的可靠性）显示，第一个工作的继电器是馈电侧的 OCR GFR，因为根据工作电流设置和工作时间，如果给定 3021 A 的故障电流，它将在 426 ms 后工作，其次是进线侧 GFR OCR 继电器，SBEF 第 1 阶段故障百分比 = 0075%，因此它的可靠性百分比为 100%。通过对比两级SBEF继电器功能实施前后导致变压器停电的故障频率，以及2019年导致马洛斯ULTG变压器停电的故障频率多达1次，2020年多达0次，可以看出马洛斯变电站发生故障时SBEF继电器的工作原理和保障措施，以及马洛斯ULTG故障的数据回顾。使用 ETAP 19.0.1 应用程序对马洛斯变电站变压器发生故障时的 SBEF 进行模拟；首次运行时为 GFR。
