Abstract

Robot sering kali digunakan untuk menggantikan tugas manusia saat membutuhkan ketelitian, kecepatan, jam kerja yang tinggi, dan kondisi yang berbahaya. Dalam pandemi COVID-19 peran robot dapat semakin penting. Salah satunya adalah robot security yang berfungsi melakukan pengamanan lingkungan. Robot security dapat difungsikan sebagai skrining awal kondisi kesehatan pengunjung suatu fasilitas umum dengan cara dilengkapi alat ukur tanda-tanda vital. Namun tanda-tanda vital tersebut harus dapat diukur secara non kontak. Sehingga dalam penelitian ini dibuat sebuah alat ukur tanda-tanda vital non kontak yang diletakan pada sebuah robot security. Tanda-tanda vital yang diukur meliputi suhu tubuh, detak jantung, dan frekuensi pernafasan. Dengan kata lain, penelitian ini melakukan integrasi pengukuran ketiga jenis tanda-tanda vital tersebut. Pengukuran suhu tubuh non kontak telah dibuat dengan cara menganalisis intensitas citra termal subjek di bagian wajah. Citra termal ini juga diproses untuk mendapatkan frekuensi pernafasan. Perubahan suhu di area lubang hidung merepresentasikan proses subjek saat menghirup dan menghembuskan udara pernafasan. Pengukuran detak jantung non kontak dilakukan dengan menggunakan teknik remote photoplenthysmograph. Algoritma yang digunakan adalah Plane Orthogonal to Skin (POS). POS bekerja dengan cara mendeteksi perubahan warna kulit wajah yang diakibatkan oleh aliran darah di bawah kulit wajah pada saat pemompaan darah oleh jantung. Berdasarkan hasil pengujian suhu tubuh, didapatkan tingkat error sebesar 0,4%. Tingkat error pengukuran frekuensi pernafasan adalah sebesar 4.72 %, sedangkan untuk detak jantung memiliki error sebesar 4,93%. Robots are often used to replace humans in certain tasks. In general, when precision, speed, high working hours, and hazardous condition. Under conditions of the COVID-19, the role of robots can be even more important. One of them is a security robot that has functions to protect the environment. Security robot can be used as an initial screening for the health condition of visitors to a public facility by being equipped with vital sign measuring devices. However, these vital signs must be measured in a non-contact manner. In this study, non-contact vital signs measurement tool was created and placed on a security robot. Vital signs measured include body temperature, heart rate, and respiratory rate. In other words, this study integrates the measurements of the three types of vital signs. Non-contact body temperature measurements have been made by analyzing the thermal image of the subject. The subject's body temperature was measured based on the intensity thermal image on the face. This thermal image is also processed to obtain the respiratory frequency. Temperature changing in nostril area represent the subject's respiration process. Non-contact heart rate measurements were performed using remote photoplethysmograph. The algorithm used is Plane Orthogonal to Skin (POS). POS works by detecting changes of facial skin color that caused by blood flow under the skin when is pumped by heart. Based on body temperature testing, an error rate of 0.4% was obtained. The error rate for measuring the respiratory rate is 4,72%, while the heart rate has an error of 4,93%.

Abstract

Logistics distribution is a series of activities that are interconnected in each process. Therefore, an information system is necessary to record, report conditions, and display the current location of items directly. An Android-based application system is vulnerable to spoofing, such as fake GPS. The application is used to falsify the coordinates of digital map locations. This research aims to develop a common tracking system and prevent Fake GPS by employing the System Development Life Cycle method, consisting of several stages, i.e., planning, analysis, design, implementation, testing, and maintenance. In this research, a prototype of the tracker tool and its information system were made. It used an RFID Smart Card for courier identity authentication and a GPS module to track position information on a digital map. RFID and GPS were controlled using the ESP32. Furthermore, the Website served as an information system to read and create a QR Code to identify the goods carried. It received data from the RFID Smart Card and GPS, stored it in the Database, and displayed it online. The test results indicated that the tracker prototype succeeded in sending location data throughout the test and gained an average distance of 6.82 meters, which was different from a commercial GPS device. It had a delay of 268.5 seconds when the location was first read. The tracker prototype had an average power consumption of 1.5 watts, an average battery life of 2 hours, 28 minutes, and 40 seconds, as well as an average battery deficiency of 36.79%. In conclusion, the system test was successful.

Abstract

Robot Security is a robot that is responsible for security as well as patrolling. When patrol automatically, the robot requires a navigation system. The robot also needs a mapping system that is used to make a map of the environment and as information on its location according to the map. The sensors used are wheel odometry and LiDAR. The wheel odometry system often slips which causes errors in reading the actual position of the robot. To fix this problem, a sensor fusion between the Inertial Measurement Unit (IMU) and wheel odometry is used. To combine these sensors, namely using the Extend Kalman Filter (EKF) which runs on the Robot Operating System (ROS) operating system. Mapping and navigation system testing, carried out using IMU sensors and without IMU, towards the 5 target points that have been made. In the test without IMU, the error of the robot reaching the target was (x = 45.86%, y = 54.595%, and = 56.63%). After adding the IMU sensor, the robot error has decreased to (x = 2.02%, y = 1.796%, and = 0.22%). In conclusion, the data combined from the IMU sensor and wheel odometry could minimize the existing slip errors.

Abstract

One of the problems that often occurs in the use of ground cables is insulation failure. This condition can cause leakage current in the 20 kV cable on the secondary side of the transformer. The greater the value of the leakage current, the more heat will cause the insulation to worsen. If this condition is not handled immediately, it can lead to the opportunity for a short-circuit current between the phase and ground. Therefore, an Internet of Thing-based monitoring tool is needed that can determine the amount of leakage current contained in the 20 kV cable on the secondary side of the transformer by applying the Kalman filter method and sending it to the substation operator using Wifi. Based on the test, it was found that the implementation of this monitoring tool obtained more constant measurement results than the actual measurement value using a measuring instrument with an average error per phase, 1.5594% phase R, 1.5535% phase S, 1.5548% phase T.
