Abstract

Rivest code 4 (RC4) adalah perhitungan kriptografi kunci simetris canggih yang memiliki mode kerja stream chipper, sehingga dalam menangani informasi dan data pada waktu tertentu menggunakan dua kotak pengganti (s-box) sebagai tampilan dengan panjang perubahan 256 dan selanjutnya s-box kedua yang merupakan elemen dari perhitungan public key. Rivest code 4 digunakan untuk menyandikan informasi, pesan atau data. Peneliti mencoba mengimplementasikan fitur login Sistem Pemilihan Ketua Umum yang menjadi pokok bahasan penelitian ini, dengan mengimplementasikan algoritma RC4 pada aplikasi yang sudah ada. Akibatnya, data terenkripsi yang tersimpan pada database akan sulit dicari tahu arti sebenarnya. Berdasarkan temuan penelitian ini, field yang berisi informasi pengguna yang mana dalam hal ini yaitu password dapat terenkripsi dengan baik, dan juga saat implementasi login juga dapat berjalan dengan baik dengan menggunakan algoritma RC4.

Abstract

This study aims to analyze library management strategies for improving student literacy in schools. Literacy is an important skill that encompasses not only reading and writing but also understanding and critically processing information. School libraries play a strategic role as learning resource centers that can support student literacy improvement if managed properly. This study used a qualitative approach with a descriptive approach. Data collection techniques included observation, interviews, and documentation. Data were analyzed using data reduction techniques, data presentation, and conclusion drawing. The results indicate that effective library management strategies include developing relevant collections, improving librarian competency, utilizing information technology, implementing engaging literacy programs, and creating a comfortable library space. Furthermore, supporting factors such as school support and adequate facilities were identified, as well as inhibiting factors such as budget constraints and low student reading interest. Efforts to address these obstacles include increasing policy support for sustainable collection development, librarian training, and collaboration with various parties. With the implementation of appropriate management strategies, school libraries can function optimally in improving student literacy.
