Abstract

Penelitian bertujuan untuk mengetahui hasil rancang hak akses komputer dengan me-manfaatkan RFID sebagai autentikasi hak akses untuk mengakses laboratorium dan komputer. Dan memahami fungsi pemanfaatan modul esp32 sebagai pusat pengiriman data pada suatu alat. Teknik pengumpulan data menggunakan studi literatur. Dalam penelitian ini dilakukan pengujian hak akses komputer pada perangkat keras. Pengujian perangkat keras dilakukan dengan menguji setiap komponen komponen yang digunakan. setelah itu diuji dengan pengujian secara keseluruhan untuk mengetahui semua komponen berfungsi dengan baik. pengujian secara keseluruhan disini dimulai dari menempelkan kartu ke RFID, setelah itu ID dari kartu akan dideteksi, apabila ID terdeteksi maka selenoid akan membuka kunci pintu dan relay menghatarkan tegangan listrik kestok kontak yang digunakan pc/komputer sehingga komputer dapat digunakan. Berdasarkan hasil penelitian, dihasilkan sebuah sistem hak akses komputer menggunakan RFID, sensor RFID akan memberikan id untuk pengenalan sistem yang akan dikirim dan diterima dikontroler sehingga kontroler mengontrol RFID, selenoid, relay, dan pushbuton.

Abstract

This study examines the performance and features comparison of three cloud-based file sharing services Google Drive, Dropbox, and OneDrive within the context of distributed systems. The primary objective is to analyze upload and download speed, security features, collaboration ease, and free storage capacity of each platform. A comparative method with direct experimentation was employed, where files sized 10 MB, 50 MB, and 100 MB were tested on each platform to obtain average transfer times. The results indicate that Dropbox excels in data transfer speed, Google Drive offers larger free storage and superior real-time collaboration features, while OneDrive stands out for its integration with Microsoft Office applications. All three services demonstrate high levels of data security and availability due to the implementation of distributed systems supporting data encryption, replication, and load balancing. This study provides insights for users to choose a storage platform that suits their needs and encourages further development of more efficient and secure cloud systems.
