Abstract

Social media is the most popular platform by the Indonesian people, starting from Facebook, Instagram and Twitter. Twitter is one of the most widely used social media, both for interacting with other people or looking for information or news that is trending topics, quickly various news or information spreads on Twitter such as issues that are currently trending, namely the Omnibus Law. , various responses given by twitter users regarding this policy that has been approved by the government. In this study, to classify the sentiments of the Indonesian people regarding the issue of Omnibus Law using the method Naïve Bayes and Particle Swarm Optimization (PSO) and divided into two test scenarios, the use of theAlgorithm Particle Swarm Optimization on Naive Bayes aims to optimize the accuracy results. The results obtained when using Naive Bayes based on Particle Swarm Optimization (PSO) are better than Naive Bayes. The best accuracy results are in scenario three with split 90% - 10% data using Naïve Bayes to get 85% results and using Naïve Bayes based on Particle Swarm Optimization the accuracy results change to higher 4% get 91% results, the amount in doing the split data is very influential on the results of the classification carried out. The response from the public is in the form of negative sentiment towards the Omnibus Law Bill.

Abstract

Malware is intentionally designed to damage computers, servers, clients or computer networks. Malware is a general term used to describe any program designed to harm a computer or server. The goal is to commit a crime, such as gaining unauthorized access to a particular system, so as to compromise user security. Most malware still uses the same code to produce another different form of malware variants. Therefore, the ability to classify similar malware variant characteristics into malware families is a good strategy to stop malware. The research is useful for classifying malware on malware samples presented as bytemap grayscale images. The malware classification research focused on 25 malware classes with a total of 9,029 images from the Malimg dataset. This research implements the VGG-16 and InceptionResNet-V2 architectures by running 2 different scenarios, scenario 1 uses the original dataset and the other scenario uses the undersampled dataset. After building the model, each scenario will get an evaluation form such as accuracy, precision, recall, and f1-score. The highest score was obtained in scenario 2 on the VGG-16 method with a score of 94.8% and the lowest in scenario 2 on the InceptionResNet-V2 method with a score of 85.1%.
