Abstract

Effective and transparent financial management is an important factor in supporting good governance in higher education institutions. At Universitas Satya Terra Bhinneka, the process of recording and managing student and organizational unit finances still faces several challenges, including the use of manual systems, limited access to financial information, and the potential for data entry errors. This study aims to develop an Android-based financial management application that assists users in recording income and expenses in a structured, accurate, and accessible manner. The development method employed in this study is the Software Development Life Cycle (SDLC) using the Waterfall model, which consists of requirements analysis, system design, implementation, testing, and maintenance. The results indicate that the developed application improves the efficiency of financial recording, facilitates real-time monitoring, and generates systematic financial reports. Based on the results of functional testing and user testing, the application is considered feasible for use as a supporting solution for financial management within the university environment.

Abstract

Keamanan informasi digital menjadi kebutuhan penting di era pertukaran data yang semakin masif. Salah satu pendekatan yang dapat digunakan adalah kriptografi klasik dengan algoritma transposisi. Penelitian ini mengimplementasikan Myszkowski Transposition Cipher sebagai metode utama untuk mengamankan dokumen digital berformat .docx. Algoritma ini dipilih karena kemampuannya dalam menangani kunci dengan karakter berulang, sehingga menghasilkan pola enkripsi yang lebih kompleks dibandingkan transposisi sederhana. Proses penelitian meliputi perancangan sistem enkripsi-dekripsi, penerapan pada file dokumen, serta pengujian melalui black-box testing dan analisis kuantitatif terhadap waktu komputasi berdasarkan variasi ukuran dokumen. Hasil implementasi menunjukkan bahwa algoritma mampu menghasilkan ciphertext yang sulit dipecahkan tanpa kunci, serta mendemonstrasikan efisiensi waktu yang layak digunakan pada dokumen berukuran kecil hingga menengah. Kesimpulannya, Myszkowski Transposition Cipher dapat diandalkan sebagai algoritma standalone untuk pengamanan dokumen, sekaligus memberi dasar empiris bagi penelitian lanjutan mengenai integrasi cipher ini dalam skema super-encryption.
