Abstract

Perkembangan teknologi informasi telah memungkinkan industri kuliner memperluas jangkauan pasar melalui platform digital. Namun, masih banyak pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) di bidang kuliner yang belum mampu memanfaatkan sistem digital secara optimal dalam mengelola dan memasarkan produknya. Penelitian ini bertujuan untuk merancang dan mengembangkan aplikasi e-commerce berbasis website bernama Nusantara Culinary guna mendukung digitalisasi di sektor kuliner. Metode yang digunakan dalam penelitian ini adalah Agile Software Development yang meliputi tahapan analisis kebutuhan, perancangan sistem, implementasi, dan pengujian. Sistem yang dikembangkan memiliki fitur utama seperti manajemen produk, pencarian produk, transaksi online, serta komunikasi antar pengguna. Berdasarkan hasil pengujian menggunakan metode black box testing, sistem yang dibangun telah memenuhi kebutuhan fungsional dan mampu memberikan kemudahan penggunaan (user-friendly) bagi penjual, pembeli, dan admin. Implementasi sistem ini diharapkan dapat meningkatkan efisiensi operasional, memperluas jangkauan pasar, serta meningkatkan pengalaman pengguna dalam mendukung pertumbuhan UMKM kuliner di Indonesia.

Abstract

The development of digital technology and audio communication has increased the intensity of information exchange through online media, but it also raises the risk of data leakage and misuse by unauthorized parties. Therefore, information security techniques are needed that not only protect the content of messages but also conceal the existence of the messages themselves. Steganography is an information security technique that embeds secret messages into a carrier medium without raising suspicion. Audio media is chosen because it has high tolerance for small changes in sound signals. This study discusses the implementation of the Echo Hiding steganography method for embedding secret messages in digital audio media. The Echo Hiding method works by adding an echo to the audio signal using specific delay time and amplitude parameters so that it does not significantly degrade audio quality. The research stages include audio data preparation, message embedding process, message extraction process, and evaluation of the stego audio quality. The expected results of this study show that the Echo Hiding method is capable of embedding and extracting messages accurately while maintaining audio quality. Thus, this method can be used as an alternative for audio-based steganographic information security.
