Abstract

The growth of technology has an important role in supporting medical equipment facilities, especially for tools for providing compression or cardiopulmonary resuscitation (CPR). CPR is a first aid measure for victims of sudden cardiac arrest in which cardiac compression is carried out for 4 cycles, each cycle consisting of 30 compressions. CPR given manually can endanger the victim due to certain factors such as insufficient or excessive pressure applied. So that the above can be realized, a tool is needed that can make it easier for someone to check their heart rate on their skin quickly and effectively. The MAX30102 sensor is a sensor that can calculate heart rate. This research aims to create an optimal automatic cardiopulmonary resuscitation device to help victims continue to breathe. This RJP tool uses a Nema 23 stepper motor as the driving motor, the motor driver uses a TB6600 driver as the motor controller. During testing, 1 minute produced 103 compressions and 30 compressions in 18 seconds. The torque strength of the stepper motor is only capable of lifting a load of 7 kg, the torque produced is 2.06 Nm. This research also uses sensors to detect heartbeats. This allows the device user to monitor the patient's heartbeat while undergoing RPJ.

Abstract

Conventional door security systems, such as padlocks and manual keys, have weaknesses, including vulnerability to duplication and the risk of loss. Biometric-based systems, such as facial recognition, offer a more reliable solution through unique user identification. This study develops a door security system using the Local Binary Pattern Histogram (LBPH) method for facial recognition, complemented by fingerprint verification as an additional security layer and real-time notifications via the Telegram application. The LBPH method was chosen for its ease of implementation and processing speed, although it has limitations such as sensitivity to lighting changes and potential recognition errors due to similar facial textures. The system utilizes LBPH for initial authentication, followed by fingerprint verification. Users also receive real-time notifications via Telegram to monitor access attempts. Testing showed a facial recognition accuracy of 85% under bright lighting conditions at distances of 30–150 cm, but it decreased to 65% in dim lighting. Fingerprint verification took approximately 2 seconds, while notification delivery required 1–2 seconds on a stable internet network. This system enhances security by ensuring only registered users can unlock the door. If facial recognition fails, the door remains locked without valid fingerprint verification.Keywords - Face Recognition, Fingerprint Sensor, LBPH, Security System, Telegram Notification.
