Because a number of company products openly donate money and goods to Israel. This has made people angry at Israel and the products that support it, thus calling for a boycott of products supporting Israel on social media. Therefore, researchers conducted sentiment analysis related to the boycott of products supporting Israel from social media X and YouTube using the Naïve Bayes algorithm with its three models, namely Multinomial, Bernoulli, and Gaussian on Indonesian and international citizens. As a result, the international dataset obtained a positive sentiment value of 79.79% with 600 data supporting the boycott, while the negative class obtained 20.21% with 152 data rejecting the boycott. Then the Indonesian dataset has a positive sentiment value of 51.78% with 1312 data supporting the boycott, while in the negative class 48.22% is obtained with 1222 data rejecting the boycott. So, in Indonesia and other countries, the majority of netizens call for a boycott of products supporting Israel through social media platforms X and YouTube. When evaluating the model, the BernoulliNB model obtained the highest accuracy value on both datasets. On the Indonesian dataset, BernoulliNB achieved an accuracy value of up to 89%. Then on the international dataset, it gets an accuracy value of 76%.</em></p> Adityo Fajar Nugroho Arry Avorizano Copyright (c) 2025 Adityo Fajar Nugroho, Arry Avorizano https://creativecommons.org/licenses/by/4.0 2025-09-30 2025-09-30 4 2 41 50 10.22236/jutikom.v4i2.18336 https://journal.uhamka.ac.id/index.php/jutikom/article/view/16018 <p> <span class="fontstyle0">Technological advancements have transformed shopping patterns from conventional to online, yet<br />many businesses still lack an effective e-commerce platform. This research aims to develop a<br />website-based e-commerce system for clothing stores using ReactJS. The system development<br />employs the Waterfall method with stages of design, implementation, and testing. The design utilizes<br />Use Case Diagrams and Sequence Diagrams, while testing is conducted using Black Box Testing<br />methodology. The result of this research is an e-commerce platform that simplifies transactions,<br />product management, and customer management, thereby increasing business efficiency and digital<br />market reach effectively and efficiently. This platform also provides customers with a more<br />convenient and faster online shopping experience.</span> </p> Zakie Nurfaiz Ramadhan Rahmi Imanda Copyright (c) 2025 Zakie Nurfaiz Ramadhan, Rahmi Imanda https://creativecommons.org/licenses/by/4.0 2025-09-30 2025-09-30 4 2 51 61 10.22236/jutikom.v4i2.16018 https://journal.uhamka.ac.id/index.php/jutikom/article/view/20496 <p><em>A server is a room used to store computer equipment. Currently, at PT SIK, the server room only uses a thermo controller to display the actual temperature inside the server room, and it is only installed within the room, making it impossible to monitor directly. Another issue is that the Air Conditioner in the server room turns off suddenly, causing the temperature to rise. Additionally, the server room administrator works 24/7 and cannot anticipate any possible failures in the server room's Air Conditioner. The researcher will attempt to collect, record, and process data on the server room temperature using a DHT22 temperature and humidity sensor connected to a NodeMCU ESP8266 microcontroller, which is connected to the internet and can send real-time notifications to the server room administrator. On the smartphone side, the Blynk application is used to view temperature and humidity graphs and to receive notifications when there is an abnormal condition in the server room.</em></p> Agus Kristiawan Masmur Tarigan Copyright (c) 2025 Agus Kristiawan, Masmur Tarigan https://creativecommons.org/licenses/by/4.0 2025-09-30 2025-09-30 4 2 62 70 10.22236/jutikom.v4i2.20496 https://journal.uhamka.ac.id/index.php/jutikom/article/view/18610 <p><em>The implementation of a cloud storage server based on SFTPGo allows users to access and manage file storage via WebGUI and SFTP clients. This study aims to develop a secure and easily accessible cloud storage system using Docker and Cloudflare Tunnel technology. The system is implemented on a Linux-based server and tested in various scenarios to ensure the reliability of WebGUI access and connectivity via the SFTP protocol. The implementation results show that the combination of SFTPGo, Docker, and Cloudflare Tunnel provides a flexible and secure storage environment. With this mechanism, users can upload and download files using predefined credentials, while ensuring that SFTP access is only possible through Cloudflare Tunnel, enhancing system security.</em></p> Zen Aufa Bahalwan Dimas Febriawan Copyright (c) 2025 Zen Aufa Bahalwan, Dimas Febriawan https://creativecommons.org/licenses/by/4.0 2025-09-30 2025-09-30 4 2 71 76 10.22236/jutikom.v4i2.18610
