Abstract

The increase in fuel prices has significant impacts on the Indonesian community's economic sector. Most people object to this policy because of its significant effects on daily life. Additionally, Indonesia's economy has not fully recovered from the Covid-19 pandemic, compounded by news of rising oil prices. With news of the increase in fuel prices, most people express sentiment regarding the rise in fuel prices on one of the social media platforms, Twitter. This study aims to differentiate the sentiment provided by the public, whether positive, negative, or neutral, using the Naïve Bayes Classifier and Decision Tree algorithms. The analysis results show that the Naïve Bayes Algorithm model, specifically Bernoulli Naïve Bayes, achieves the highest accuracy of 65.60%, with a precision of 68%, recall of 60.30%, and f1-score of 59.33%.

Abstract

In this study, the researchers found a way to help teachers input student grades and achievements. Currently, records are still kept in books, which can cause problems such as burning, deterioration over time, or damage caused by pests. The purpose of this study is to create a system that can be a solution to the above problems, which will also make it easier for teachers to monitor their students so that they can report to the students' guardians. The researcher hopes that this system can help in monitoring student development. Blackbox testing was conducted to show that all features functioned as expected. In addition, a user survey was conducted, which showed a satisfactory rating of 60%, particularly for the interface design. However, the system performance still needs improvement because errors occurred in several aspects and received a low satisfaction rating of less than 50%. There are still many shortcomings in this research that need to be addressed. Hopefully, future research can improve on these shortcomings, resulting in a useful project.
