Abstract

Mobile Ad-hoc Network (MANET) is a mobile network, due to its nature MANET has basic weaknesses in its reliability when traffic is high. High network traffic is caused by one of the factors including the size of the packets being transmitted, which can cause smaller packets to be susceptible to not reaching the recipient or packet loss. Packet Scheduling is one solution to address these issues. This research uses Priority Packet Scheduling method based on the size of the data packet. Data packets with a size greater than 1000 bytes will be given high priority and sent first. Packets with a size between 1000 bytes and 500 bytes will be given medium priority and packets below 500 bytes will be given the lowest priority. Each priority will still receive a sending quota to prevent starvation. The results of Priority Packet Scheduling show that the method does not have an impact on the Packet Delivery Ratio and even experienced an increase in Average End-to-End Delay when compared to not using Priority Packet Scheduling. However, the Average Throughput values obtained with this method are significant.

Abstract

Advances in technology make people tend to choose online transactions compared to cash. With the rapid development of technology, PT Pertamina launched their newest program, the MyPertamina application. The MyPertamina application is a combination program between loyalty and e-payment. The MyPertamina application has many users, so there are often positive and negative reviews that are irrelevant to the rating given on the Google Play Store. MyPertamina application review data will be obtained using the Web Scraping technique using the Google-Play-Scraper API. The scraped data will then be subjected to text preprocessing to clean the text so that the data can be executed. Sentiment analysis can detect whether a text contains positive or negative opinions from user reviews that are not in accordance with the rating. Random Forest is a method in analysis consisting of several decision trees as a classifier. In this study, the random forest method was used by dividing two sentiment classes, namely positive and negative, taking evaluation indicators, namely accuracy, recall, precision and f1-score. Tests were carried out based on the number of trees and tree depth on 800 data by dividing the data by 250 data per class. Based on the results of the tests and analyzes that have been carried out, with a comparison of training data and test data 80%:20% obtained values of 90% accuracy, 90% precision, 91% recall, and 89% F1-Score with a depth of 80 trees and 50 tree depths.

Abstract

Stress is a state of pressure on a person due to something that happens not as expected or unwanted. Stress can risk disrupting a person's health, both physical aspect and mental aspect, and reduce their quality of life as well if not treated immediately. A person's heart rate and GSR (Galvanic Skin Response) can be used as features to detect stress. Both features are influenced by sympathetic nerves that regulate a person's response to emotions so that they can be used to identify a person's stress level. The K-Nearest Neighbor (k-NN) method is used as a classification method because it has advantages in accuracy using data with few parameters and a large amount of data. The tool uses Arduino Uno as a microcontroller, MAX30102 sensor to measure heart rate, Grove GSR sensor to measure GSR, and LCD to display the output. Testing was carried out using 10 subjects as test data, and using 70 training data. The results of system testing in this study are based on the accuracy of the tool's readings compared to the results of the subject's questionnaire. The accuracy produced by this stress detection system is 70%. For the results of testing the k-NN method on this system has an accuracy of 64.29% for 70 training data. While the results of testing the computation time of the system get an average computation time of 13.3 ms.
