Abstract

The rapid growth of IoT devices has brought significant security challenges, particularly in detecting various types of attacks within heterogeneous network environments. This study explores the effectiveness of data balancing techniques, including Random Undersampling (RUS), Cost-Sensitive Learning (CSL), Synthetic Minority Oversampling Technique (SMOTE), and Randomized Combination Sampling (RCS). Feature selection methods, namely correlation (threshold 0.8) and mutual information (top 15 features), were employed to optimize feature sets. The Decision Tree (DT) and Linear Discriminant Analysis (LDA) classifiers were used to evaluate the performance of balanced datasets. The evaluation metrics included accuracy, precision, recall, F1-score, G-mean, and ROC curves. The results revealed that SMOTE and RCS outperformed other balancing methods, with SMOTE achieving the highest accuracy (98.7%) and RCS demonstrating robust G-mean values across both feature selection techniques. DT consistently showed better performance compared to LDA across all metrics, while feature selection significantly improved the classification results, particularly under mutual information criteria. However, the analysis highlighted limitations of LDA in handling imbalanced datasets and high-dimensional features. This study concludes that a combination of advanced data balancing and effective feature selection significantly enhances the accuracy of intrusion detection in IoT networks. Future work will focus on integrating real-time detection systems and exploring hybrid models to further improve the detection of complex attacks in dynamic IoT environments.

Abstract

Pada masa saat ini sistem sangat banyak digunakan di kalangan manusia untuk interaksi teknologi informasi yang sangat cepat berkembang, mulai dari penggunaan teknologi untuk pendidikan, bisnis, maupun geografis. Webshop saat ini banyak digunakan untuk melakukan pemesanan secara online tanpa harus datang ke tempat yang berbasis web. Penelitian ini dilakukan di salah satu toko online yang ada di Palembang untuk memenuhi kebutuhan digitalisasi. Metode yang digunakan pada perancangan  maupun pengembangan yaitu metode waterfall, dengan sistem ini peneliti berharap bisa memenuhi kebutuhan digunakan dalam pemesanan online yang memudahkan pemesan untuk diera di mana kebutuhan serba online. Berdasarkan hasil penelitian pada toko Yhoophii Shop dalam proses pemesanan dan penjualan masih bersifat pasif sebatas melakukan penjualan di toko serta bersifat verbal dengan menawarkan produk dari mulut kemulut dan belum menggunakan teknologi yang berbentuk website. Dengan adanya website yhoophii shop ini dapat membantu toko dalam meningkatkan pemasaran produk dan toko dapat dikenal oleh masyarakat luas.

Abstract

The development of information technology has driven major changes in corporate promotion and communication strategies, one of which is through the use of company profile websites. This study aims to design and implement a web-based company profile website for PT Mitra Makmur Global; a company engaged in the heavy equipment rental sector. The research method used is a qualitative method with a Waterfall system development model, which includes the stages of needs analysis, system design, implementation, testing, and maintenance. The website is designed to provide information about the company profile, vision and mission, services, and contacts in an interactive and easily accessible manner. The implementation results show that the company profile website is able to improve the company's professional image, expand the reach of promotions, and make it easier for potential clients to obtain information related to the company's services. In addition, the implementation of a responsive interface design and structured navigation makes users feel more comfortable in navigating the site. In conclusion, the development of the PT Mitra Makmur Global company profile website plays a significant role in strengthening the company's digital presence, increasing customer trust, and becoming an effective promotional tool in the digital era.

Abstract

Electrical energy efficiency is an essential requirement in supporting environmental sustainability. Lamps, as one of the most frequently used electrical devices, contribute significantly to energy consumption in both households and industries. This study aims to design an Internet of Things (IoT)-based current monitoring system for lamps using the Blynk application. The system is built using a NodeMCU ESP8266 as the main controller and a PZEM-004T sensor as a measuring tool for voltage, current, power, and energy. The test results show that the system can operate in real time to monitor electrical parameters and display data through the Blynk application on a smartphone. The measurement accuracy reaches ±3.8%, with influencing factors including voltage stability and internet connection quality. This system has proven effective as an electrical energy monitoring solution that supports energy conservation and electrical safety.

Abstract

Perkembangan teknologi informasi yang pesat mendorong berbagai sektor untuk bertransformasi menuju sistem berbasis digital, termasuk industri pariwisata. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem informasi pemesanan paket wisata berbasis web pada Nusa Indah Travel di Kota Palembang. Sistem ini dikembangkan untuk mengatasi permasalahan yang sering terjadi pada sistem manual, seperti keterlambatan pemesanan, kesalahan data, dan keterbatasan akses informasi. Dengan menggunakan model pengembangan Waterfall, sistem dibangun melalui tahapan analisis kebutuhan, perancangan, implementasi, pengujian, dan pemeliharaan. Hasil penelitian menunjukkan bahwa sistem mampu memberikan kemudahan bagi pelanggan dalam mencari dan memesan paket wisata, melakukan pembayaran secara online, serta memperoleh informasi perjalanan secara real-time. Sementara itu, pihak admin dapat dengan mudah mengelola data pengguna, transaksi, dan laporan operasional. Penerapan sistem ini tidak hanya meningkatkan efisiensi kerja dan akurasi data, tetapi juga mendukung peningkatan kualitas pelayanan serta daya saing agen travel di era digital.
