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

Salted egg is one of the egg types that has a lot of devotees because it tastes a little salty and savory. Salted eggs are usually homemade in various regions. The easy process of making them has attracted many people to do so. This study developed a PLC-based on automatic system for a salted egg maker using the osmotic pressure method to accelerate the opening of the semi-permeable membrane on duck eggshells so that the salting mixture seeps into the eggs more quickly. It was carried out in an osmotic pool containing water and acetic acid at a concentration of 5%. The data collection process in designing the salted egg maker consisted of evaluating the performance of photoelectric sensors, proximity sensors, temperature controller, thermostat set point, baking time, and salted egg durability test. The results of the tests indicated that the time needed to make salted eggs from raw eggs to cooked eggs only took 36 minutes using the machine designed. Additionally, the presented salted egg maker reveals the short making time, and long salted egg durability. altogether revealing full potential to be easily used for practical applications.

Abstract

Perkembangan dunia teknologi pada saat ini telah mencapai titik dimana semua aktifitas dapat digantikan oleh mesin, dimana mesin adalah sebagai alat bantu manusia dalam melakukan banyak hal. Untuk membuat sebuah mesin dapat beroperasi secara otomatis dibutuhkan beberapa bagian, diantaranya software, hardware dan mekanik. Pada pelatihan yang di selenggarakan oleh Program studi Teknik elektro ITATS ini adalah dengan membuat sebuah sistem pengatur kecepatan motor menggunakan mikrokontroler. Target pelatihan ini adalah siswa SMK area Surabaya, pelatihan dilakukan dengan beberapa tahap, proses pembuatan program, proses memasukkan program dalam mikrokontroler untuk mengatur nyala LED dan mengatur kecepatan motor. Dari hasi pelatihan yang telah dilakukan mendapatkan bahwa siswa SMK mampu membuat sebuah program sederhana untuk mengatur menyalakan lampu LED, mengatur kecepatan motor, dimana untuk kecepatan motor di bagi menjadi tiga, kecepatan lambat, sedang dan kecepatan tinggi. Dari pelatihan ini diharapkan siswa SMK mampu membuat sebuah sistem sederhana menggunakan mikrokontroler untuk membuat sebuah sistem otomatis.

Abstract

Wireless LAN (WLAN) network quality in indoor environments is significantly affected by distance, building conditions, and physical obstacles such as concrete walls, glass, and other materials. Manually testing WiFi signal quality at multiple points is repetitive, time-consuming, and potentially leads to data inconsistencies. Therefore, this research aims to design and build a WiFi service coverage area testing system using a Raspberry Pi 3-based remote-controlled wheeled robot as a more efficient and controlled measurement alternative. The robot functions as a mobile platform that acts as a WiFi client to measure Received Signal Strength Indicator (RSSI) values ​​at various coordinate points in the test environment. The system was developed using a Raspberry Pi 3 as the control center, Python programming for the control system and RSSI reading using the PyWiFi library, and OpenCV for real-time camera display. The robot is controlled via a remote interface and moves according to a predetermined coordinate scheme. Tests were conducted at 35 measurement points, comparing the RSSI results from the robot prototype with the WiFi Analyzer application on an Android device. The test results show that RSSI variations are influenced by the distance from the access point and the physical environmental conditions. Data comparison shows an average error percentage of 5.51%, which indicates a system success rate of 94.49%.

Abstract

Traditional storage cabinets that rely on conventional locks and provide unrestricted access are highly vulnerable to theft. To safeguard documents and other valuable items from loss, an integrated security system is required to regulate and secure access to storage compartments. This study aims to develop a security system based on facial recognition, ID cards, and a keypad interface The Haar Cascade classifier combine with LPBH utilizing the OpenCV library is employed for facial identification by storing 30 photos per person in a designated folder, and subsequently comparing facial objects captured by a webcam against pre-stored and trained facial data in the database. The analysis indicates that the optimal detection range of the system is between 100 and 300 cm. In facial orientation testing, the best recognition performance is achieved at angles between 0° and 40°. Based on 20 experimental trials, the system demonstrates an average success rate of 80%. These results suggest that a facial‑recognition‑based security system utilizing the Haar Cascade approach is feasible for implementation as a protective mechanism for storage cabinets.
