Abstract

Abstract: In today's era of globalization, information technology plays a very important role in processing data and transforming it into accurate information. SMK Swasta Swakarya Binjai currently faces several recurring problems. Until now, the recording of book loans and returns has been done manually, which has made it difficult to retrieve information. The current system for recording book collections, member data, borrowing, returning, and fines is still done by writing in a ledger, which is felt to be ineffective and inefficient for library management. This makes it difficult for library members to find the books they want to read and complicates the process for staff to update the existing book data. This issue serves as the basis for developing a research system for book borrowing and return processes. The objective is to create an application for book borrowing and return processes. It is hoped that the developed application will successfully address the existing issues and facilitate both library members and administrators in conducting book borrowing and return processes at the library. Keywords: System, Borrowing, Returning, Books, Library Abstrak: Pada era globalisasi saat ini, teknologi sistem informasi mempunyai peranan sangat penting dalam mengolah data, memproses data, dan mengubah data untuk mendapatkan informasi yang akurat.

Abstract

Dalam suatu perusahaan pengadaan barang dan jasa, tidak terlepas dari yang namanya tender. Pada PT. Bumi Balakka Maju Sejahterah sendiri tender merupakan hal yang utama di dalam perusahaannya. Namun sayang proses penentuan keikutsertaan tender masih dilakukan secara manual sehingga pada saat penentuan tender yang akan diikuti tidak memiliki regulasi yang tetap, dan tidak sesuai dengan keadaan perusahaan, maka dari itu pemilihan tender sering mengalami kurangnya efisien dan efektifitasnya. Untuk membantu agar proses pemilihan tender yang lebih baik kedepannya, maka dibutuhkan sebuah Sistem Pendukung Keputusan yang merupakan sistem berbasis komputer sehingga dapat membantu mendukung sebuah keputusan yang dihasilkan melalui dukungan metode WASPAS dengan menentukan nilai terbesar, maka prioritas tender yang paling tinggi akan didapat. Berdasarkan hasil dari penelitian ini, Sistem Pendukung Keputusan berhasil dibangun guna membantu masalah untuk menentukan keikutsertaan tender pada PT.Bumi Balakka Sejahterah. Sehingga tender yang diprioritaskan untuk diajukan sesuai dengan kapabilitas yang dimiliki.

Abstract

This paper presents the design and implementation of a cryptographic scheme that combines the Hill Cipher algorithm with the Three-Pass Protocol (TPP) using mod-256 arithmetic. The objective is to provide a secure communication mechanism without direct key exchange while adapting a classical cipher to modern digital contexts. The system employs a 2×2 key matrix where plaintext characters are mapped to their ASCII values, grouped into vectors, and transformed through matrix multiplication followed by modulo reduction. The TPP structure allows both sender and receiver to apply their private keys independently, producing layered ciphertexts before the final recovery of the plaintext. A prototype application was developed using Microsoft Visual Studio 2010 (Visual Basic) to validate the approach. The program includes input fields for plaintext, ciphertext at each stage, key matrices, and a log box that records the detailed matrix operations for transparency. Experimental results demonstrate that the original plaintext can be accurately restored after multiple encryption and decryption phases, while the intermediate ciphertexts remain random and unintelligible. The findings confirm that integrating Hill Cipher with the Three-Pass Protocol strengthens confidentiality and eliminates the need for key distribution. Beyond its security benefits, the prototype also serves as an educational tool, helping students and practitioners understand both matrix-based encryption and keyless secure communication protocols.
