IMPLEMENTASI BACKEND SYSTEM UNTUK INTEGRASI PAYMENT GATEWAY PADA SISTEM PEMBAYARAN KOST MENGGUNAKAN EXPRESS.JS

IMPLEMENTATION OF A BACKEND SYSTEM FOR INTEGRATION OF PAYMENT GATEWAY IN THE BOARDING PAYMENT SYSTEM USING EXPRESS.JS

Rumah kost menjadi pilihan populer bagi mahasiswa, pekerja, dan pelancong karena lokasinya yang strategis, fasilitas lengkap, dan harga terjangkau. Meski sistem informasi kost telah ada untuk manajemen penyewa dan pembayaran, banyak yang masih menggunakan metode pembayaran semi-tradisional. Oleh karena itu, diperlukan teknologi modern seperti payment gateway Midtrans. Integrasi langsung dengan payment gateway melalui frontend memiliki kelemahan dalam keamanan data dan fleksibilitas. Penelitian ini merancang dan membangun Backend System untuk menambahkan mekanisme keamanan pada system pembayaran kost. Hasil pengujian menunjukkan Backend System mampu menambahkan mekanisme keamanan dengan mengamankan client key di sisi server dan mengurangi risiko akses tidak sah.

Boarding houses are a popular choice for students, workers and travelers because of their strategic location, complete facilities and affordable prices. Although boarding house information systems exist for tenant management and payment, many still use semi-traditional payment methods. Therefore, modern technology such as the Midtrans payment gateway is needed. Direct integration with payment gateways via the frontend has weaknesses in data security and flexibility. This research designs and builds a Backend System to add security mechanisms to the boarding house payment system. Test results show that the Backend System is able to add security mechanisms by securing client keys on the server side and reducing the risk of unauthorized access.
