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

The rapid development of technology at present is almost utilized in every aspect of life, including education, economy, social, and health. However, the equal distribution of this technology has not been fully implemented, especially in the field of health. According to data from Databoks in 2022, 71% of the population has never accessed health services online. This serves as the basis for the creation of the User Interface (UI) and User Experience (UX) for health service applications (homecare) using the Double Diamond method, which is divided into four stages: discover, define, develop, and deliver. Data collection in this research is conducted through literature studies, interviews, and observations. Additionally, usability testing is performed using the System Usability Scale (SUS), with a testing result of 83.3%, categorized as excellent. This can contribute to a positive user experience for the users.

Abstract

E-commerce is a buying and selling process carried out via a digital platform, utilizing the internet as a transaction medium. The existence of e-commerce makes it easier to buy and sell online, which is the key to business development and potential profits in the future. Online business competition is increasingly intense, even reaching price competition. Bratajaya Farm Animal Shop chose to use the e-commerce platform as a way to sell their products. With this e-commerce, it is hoped that it will make it easier for customers to look for sacrificial animals without having to come directly to the shop which takes time. E-commerce technology design for the sale of sacrificial animals at the Bratajaya Farm Shop using the PHP programming language and MySQL database and testing using Blackbox testing. The method used for the E-Commerce system uses Content Based Filtering, with the Content Based Filtering method it can make it easier for customers to search for the animal category to choose

Abstract

In today's telecommunication world, we cannot be separated from long-distance communication using telephones, either personal needs or mass needs. Therefore, this research aims to introduce a system that may be less familiar today, namely the VoIP System Implementation Using Issabel as an Integrated IP PBX Server with Telco Vendors. In this research, the author conducted experiments using VirtualBox to support thesis writing and using one of the providers that the author borrowed from the office in order to make calls to GSM and PSTN. The author observes that currently there are quite a lot of call centres that need this system to support employee performance and cost efficiency. Through this journal, the author hopes that entrepreneurs or telecommunication companies can gain an understanding of the VoIP System and IP PBX Server to be implemented.

Abstract

Using the Convolutional Neural Network (CNN) algorithm, this research aims to create a better lecturer attendance application that improves the attendance system and creates peace of mind when lecturers arrive at national universities. The author analyzes the results of applying deep learning algorithms to an experimental face recognition system that uses convolutional neural networks. The purpose of this study is to show that deep learning algorithms can improve the accuracy and efficiency of recording presence. In addition, the goal of this research is to create a timekeeping application using face recognition technology that is expected to have a high level of accuracy. In addition, this research includes a modification of the CNN model. This modification resulted in an epoch value of 75 for training of 100% and test of 95%. Analysis of results, drawing conclusions, and suggestions for additional development are the final stages of this research. Evaluation of the integrated system is done by collecting actual attendance data and comparing it with the attendance records created by the system. This validation will help explain the performance of the system and find problems or vulnerabilities that may need to be fixed
