Abstract

Data security in sales information systems has become a critical priority in today's digital era. Ilham Banjar Store needs a system that can effectively protect user data, especially in login and registration features, which are vulnerable to security threats. The lack of encryption mechanisms in the current system results in user data, such as passwords, being transmitted in plaintext, increasing the risk of unauthorized access and data modification. Therefore, this study aims to enhance the security of the Ilham Banjar Store's sales information system by implementing the Advanced Encryption Standard (AES) 256-bit Cipher Block Chaining (CBC) method in the login and registration processes. The research method used is Research and Development (RD), consisting of stages such as literature review, needs analysis, system design, implementation, testing, evaluation, and analysis. The implementation of the Advanced Encryption Standard (AES) involves the encryption processes of AddRoundKey, SubBytes, ShiftRows, and MixColumns, and the decryption processes are the inverse of these encryption steps. Testing includes measuring encryption and decryption times as well as verifying data integrity using HMAC (Hash-Based Message Authentication Code). The research results show that the performance testing indicates encryption and decryption times remain within acceptable limits, and the encrypted and decrypted data maintain their integrity. Thus, the new system meets both security and performance requirements.

Abstract

Efficient feed management is crucial for successful fish farming. Improper feed management leads to waste, poor water quality, fish mortality, reduced yields, and decreased operational efficiency. A primary challenge is determining appropriate feed rations based on fish growth stages. This research developed a web-based information system to aid fish farmers in efficient and accurate feed management. The system calculates feed rations using a formula based on fish biomass and incorporates feed efficiency analysis via the Food Conversion Ratio (FCR). A Prototype Model was used for system development due to its adaptability to user feedback. Results show the system automatically calculates feed rations, manages fish sampling data, analyzes feed efficiency using FCR, and generates daily reports for efficient feed management. Field trials validated the system's effectiveness, demonstrating its ability to provide information on feed efficiency and reduce feed waste.

Abstract

Prima Wash merupakan salah satu usaha pelayanan jasa cuci motor dan mobil yang berlokasi di Ciamis, Jawa Barat. Permasalahan yang muncul adalah kesulitan dalam pencatatan pembayaran manual, mengelola dan mengontrol pesanan yang masuk, terutama pada hari sibuk dimana pencatatan pesanan ditulis dalam buku kertas yang memungkinkan proses rekapitulasi menjadi lama. Selain itu untuk mengetahui banyak atau tidaknya antrian, pelanggan harus datang ke lokasi. Berdasarkan permasalahan tersebut maka diperlukan sebuah sistem layanan jasa kendaraan cuci motor dan mobil berbasis WEB. Dalam penelitian ini, digunakan metode Rapid Application Development (RAD) yang memungkinkan pengembangan sistem secara cepat dan berulang. Metode RAD berfokus pada kebutuhan pengguna dan melibatkan partisipasi aktif dari pengguna dalam setiap tahap pengembangan. Tahap-tahap dalam metode ini meliputi Perencanaan Kebutuhan (Requirements Planning), Desain Pengguna (User Design), Pembangunan ( Construction), dan Pengujian(CutOver). Desain diagram model sistem yang digunakan pada penelitian ini, menggunakan diagram UML yang meliputi use case diagram dan class diagram. Metode Pengujian yang digunakan adalah metode black box dengan hasil kesimpulan valid. Hasil dari penelitian ini adalah rancangan sistem informasi berbasis WEB untuk layanan cuci motor dan mobil yang sesuai dengan kebutuhan Prima Wash. Sistem ini menghasilkan beberapa fitur yaitu fitur login pengguna, kelola pengguna, lihat antrian, fitur booking online, transaksi pembayaran, input antrian, kelola konfirmasi pembayaran, dan registrasi pengguna.
