Abstract
Perkembangan teknologi Internet of Things (IoT) memberikan peluang dalam meningkatkan efisiensi pencatatan dan pengelolaan stok barang pada suatu usaha. Toko Raja Intan masih melakukan pencatatan stok barang secara manual menggunakan buku, sehingga proses pencatatan membutuhkan waktu dan dapat menimbulkan kesalahan dalam mengetahui jumlah stok barang. Penelitian ini bertujuan untuk merancang dan membangun sistem scan barcode barang berbasis IoT yang dapat membantu proses pencatatan stok barang masuk dan stok barang keluar secara lebih terstruktur. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan delapan tahapan, yaitu studi pendahuluan, perencanaan, pengembangan produk awal, uji coba awal, revisi produk, uji coba lapangan, revisi produk akhir, dan produk akhir. Sistem yang dibangun menggunakan ESP32 sebagai pusat pengendali yang terhubung dengan scanner barcode, LCD 20x4, buzzer, serta database Supabase melalui jaringan internet. Pada sistem ini, barcode digunakan sebagai trigger atau kunci akses untuk menjalankan proses stok yang telah dipilih oleh pengguna, bukan sebagai tempat penyimpanan data barang. Hasil penelitian menunjukkan bahwa sistem dapat menjalankan proses pemilihan barang, pemindaian barcode, pencatatan stok masuk dan stok keluar, serta penyimpanan dan pembaruan data pada database. LCD 20x4 dapat menampilkan informasi hasil proses. Berdasarkan hasil pengujian, sistem yang dibangun dapat digunakan sebagai alat bantu untuk mempermudah pencatatan dan pengelolaan stok barang pada Toko Raja Intan. Kata Kunci: Internet of Things, Scan Barcode, Database Supabase ================================================== Advancements in Internet of Things (IoT) technology offer opportunities to enhance the efficiency of inventory recording and management for businesses. Currently, Toko Raja Intan records inventory manually using logbooks; this process is time-consuming and prone to errors regarding stock quantity accuracy. This study aims to design and develop an IoT-based barcode scanning system to facilitate a more structured process for recording incoming and outgoing stock. The research employs the Research and Development (R&D) method, comprising eight stages: preliminary study, planning, initial product development, preliminary testing, product revision, field testing, final product revision, and the final product. The system utilizes an ESP32 microcontroller as the central controller, connected to a barcode scanner, a 20x4 LCD, a buzzer, and a Supabase database via the internet. In this system, the barcode serves as a trigger or access key to execute inventory processes selected by the user, rather than as a storage medium for item data. The results demonstrate that the system successfully handles item selection, barcode scanning, the recording of incoming and outgoing stock, and data storage and updates within the database. The 20x4 LCD displays the results of these operations. Testing indicates that the developed system serves as an effective tool to streamline inventory recording and management at Toko Raja Intan.
