Abstract

Facial expressions play an important role as a non-verbal language rich in emotional information, especially in psychological contexts. The main challenge in this research is to understand and analyse complex facial expressions, which are often difficult for psychologists to interpret. The implementation of webcam-based facial expression recognition leverages the computer's ability to visually recognise human emotions, supported by artificial intelligence and machine learning. Convolutional Neural Network (CNN) and OpenCV methods are used to detect and classify facial expressions directly. The CNN model is trained using a dataset with six expression classes (happy, sad, angry, surprised, neutral, afraid), with four convolution layers for multi-class classification. The implementation of facial expression recognition is successful, the system captures facial images from a webcam, detects faces in the frame, and classifies facial expressions directly on the screen window. The performance of training data against the trained model measured using Classification Accuracy shows an accuracy of 72.34% in training accuracy and 60.54% in validation accuracy. While the performance of the facial expression recognition system calculated using Confusion Matrix resulted in an accuracy of 70.55%. The calculation results show that the model is at the Fair Classification parameter level or able to classify facial expressions in humans with a fairly good level of accuracy, this research has great potential for application development in the field of psychology. However, further optimisation is needed by involving experts to ensure its effectiveness.

Abstract

Cigarette smoke is a source of pollution which contains various substances such as nicotine, tar, carbon monoxide gas (CO) and carbon dioxide gas (CO2) which harm the body's health. Cigarette smoke is inhaled by active smokers and passive smokers, namely people who do not smoke, but are exposed to and inhale cigarette smoke from the surrounding environment. WHO data shows that 8 million deaths were caused by cigarette smoke, 1.2 million of which were passive smokers. Currently, in several places special smoking rooms have been provided, however, cigarette smoke flowing outside the room still causes pollution. Reducing air pollution is crucial and must be provided with a solution, including by filtering the air from smoking rooms. This research aims to build a prototype system for monitoring, filtering and automatically disposing of indoor cigarette smoke. The prototype reduces the level of cigarette smoke in the room until it reaches normal conditions (400-1000 ppm) and filters the cigarette smoke produced from the smoking room before it is released outside the room. The NodeMCU ESP-32 is used as a microcontroller and is equipped with an MQ-2 sensor which is capable of detecting various types of gas including carbon monoxide (CO), carbon dioxide (CO2) and cigarette smoke, as well as activated carbon as the main ingredient in the cigarette smoke filtering process. Activated carbon has high absorption capacity so it is effective as an air purification medium. The system test results succeeded in detecting, monitoring, filtering and disposing of filtered smoke with an average level of filtered cigarette smoke of 249.5 ppm.
