Teaching aids are used in the field of education to streamline the implementation of the learning process. In this research, AC servo motor learning media with type R88M-1M10030-S2. The learning media will focus on controlling the position and speed of the servo motor for the x, y and z axes. This research uses the experimental work method. Testing of this research is carried out in Motion Variety parameter testing, NC function testing, HMI function testing, and user evaluation testing. It was found that the percentage of deviation value was 4.9%. In position testing, the deviation value of the X and Z axes has a small average final error with an X-axis error value of 0.21% and a Z-axis of 0.24%.

Abstract

ABSTRAKKendali ketinggian air merupakan suatu sistem yang sering ditemukan di sebagian besar fasilitas industri. Kendali ketinggian air seringkali dihadapkan pada gangguan yang disebabkan perubahan aliran masuk serta perubahan laju pengeluaran air. Penelitian ini bertujuan untuk meningkatkan kendali ketinggian air dalam sistem dengan kendali Fuzzy PID dalam menghadapi variasi gangguan berupa perubahan laju pengeluaran air, serta mengimplementasikan pada kontroler PLC. Penelitian ini melibatkan pengujian kendali Fuzzy PID dan kendali PID dengan metode tuning Ziegler-Nichols 1. Variasi gangguan berupa keluaran pompa DC yang bisa diatur kecepatannya dari Output DA PLC resolusi 0-6000 yang dikonversi menjadi 0-100%. Hasil penelitian menunjukkan Fuzzy PID dapat diimplementasikan pada PLC dengan hasil yang minim overshoot, settling time yang lebih pendek rata-rata 17.23 detik sedangkan PID rata-rata 78,4 detik dan terdapat overshoot. Namun, Fuzzy PID cenderung memiliki rise time lebih lambat 1-2 detik daripada kendali PID.Kata kunci: PLC, Fuzzy PID, PID, Water Level, Ziegler-Nichols ABSTRACTWater level control is a system that is often found in most industrial facilities. Water level control is often faced with disturbances caused by changes in the inflow and changes in the rate of discharge of water. This study aims to improve the control of the water level in a system with Fuzzy PID control in dealing with variations in disturbances in the form of changes in the rate of water discharge, and to implement it on the PLC controller. This study involves testing Fuzzy PID control and PID control using the Ziegler-Nichols 1 tuning method. The disturbance variation is in the form of a speed-adjustable DC pump output from the PLC DA Output with a resolution of 0-6000 which is converted to 0-100%. The results showed that Fuzzy PID can be implemented on PLCs with minimal overshoot results, shorter settling time with an average of 17.23 seconds while the average PID is 78.4 seconds and there is overshoot. However, Fuzzy PID tends to have a slower rise time of 1-2 seconds than PID control.Keywords: PLC, Fuzzy PID, PID, Water Level, Ziegler-Nichols

Abstract

The increasing complexity of industrial automation technology today requires industries to upgrade their existing systems, such as IoT-based SCADA, which allows for real-time production monitoring from anywhere. However, to achieve this, a system is needed that does not affect or halt the production process and does not require replacing the existing system during the upgrade process. Therefore, a system that can adapt to the existing one is necessary. This research aims to implement an IoT-based SCADA system in an existing plant by integrating the system with ctrlX Automation to address this issue. The implementation is carried out in several stages. The first stage involves integrating the plant controlled by the Omron CP1L PLC with ctrlX Automation. The second stage is creating tags for the SCADA system using tools installed on ctrlX Automation. The third stage involves developing the user interface. The fourth stage is the remote access communication process for the IoT system using the OpenVPN Cloud tool. The test results show that the integration between the Omron CP1L PLC and ctrlX Automation was successful, with a 100% tag retrieval rate from the Omron CP1L PLC, and the data could be visualized. The user interface can be accessed, and remote access can be performed on different networks and locations using the OpenVPN Cloud tool. During testing, the average data transfer write-read delay with one address/tag during remote access was 61.3ms, and for the write-read test with three addresses simultaneously, the average was 78.1ms. Based on these results, the data transfer process using ctrlX Automation integrated with the Omron CP1L PLC can be categorized as very good.

Abstract

Job safety in the construction sector in Indonesia is a pressing issue, with accident rates still high despite conventional efforts to improve them. This research aims to overcome this issue by utilizing the Internet of Things (IoT) through Smart Helmets. The Smart Helmet is equipped with an Inertial Measurement Unit (IMU) sensor to detect falls and monitor worker orientation and movement in realtime. This system uses MongoDB for data storage and Real-Time Locating System (RTLS) with ESP32 and HELTEC LoRa32 V2 for signal transmission. The MPU9250 9DOF sensor is used to obtain data from the IMU, while Sensor Fusion and Kalman Filter are used to increase the accuracy of sensor data measurements. The research design research method is applied through the needs identification, design, implementation and evaluation stages. The results of this research are able to monitor workers' movements and orientation and detect work accidents in the construction sector.

Abstract

Since March 2020, coronavirus disease (COVID-19) has become a major global concern. Even in an emergency, medical personnel should avoid contact with COVID-19 patients. Mobile manipulators are a non-contact alternative to medical personnel for performing healthcare tasks such as distributing supplies to COVID-19-quarantined patients. In this study, patients use an Android application to order mobile manipulator robots, which include the Collaborative Manipulator Robot UR5e and the autonomous mobile robot MiR200 (abbreviated and referred to as CURe-Mi). The HTTP protocol is used for communication between the Android application and the robot. The experiment was conducted in a small room with several tables and bottles used to simulate hospital rooms and medications. The delivery testing results show that all four items were delivered successfully. The results of the manipulator robot and mobile robot movement accuracy tests show that the average error is 0.213 and 4.51 cm, respectively. The Android application performance test demonstrates that the application successfully sends commands to the mobile manipulator robot within its maximum range of 1,800 cm. The CURe-Mi mobile manipulator robot has successfully assisted medical personnel in handling several contactless COVID-19 patients serving missions.

Abstract

The electrocardiogram (ECG) and heart rate are parameters used in the analysis and cardiac activity. Monitoring and analysis is currently still being carried out face-to-face. In this study used the Internet of Things (IOT) and the web-based interface, This is done so that the process of monitoring and analysis of ECG waveforms can be done anywhere and anytime by medical personnel. This study is a continuation of monitoring ECG and heart rate, an AD8232 modul were used to read and conduct bio-voltage signal conditioning from the body with the help of the electrodes. The electrode tapping technique is determined based on Einthoven's triangle theory. In addition, the NodeMCU microcontroller is used to control output and allows running an Internet of Things (IoT) system. Also performed EKG wave output testing, the success rate of data transmission, the realization of the interface as well as testing the accuracy and precision of heart rate values. The results showed that the resulting ECG waves had a frequency of 40Hz and a QRS complex wave period of 0.10 second. In addition, the percentage of success rate of data transmission is 98.84%. Also obtained a heart rate measurement accuracy of 97.966% and a precision level of 0.658%. An interface has also been realized that can display ECG waves in the order of milliseconds and milliseconds.
