Sekolah Sukma Bangsa Pidie telah menerapkan aturan lingkungan, namun pendekatan berbasis sanksi dan pencatatan manual belum mampu mendorong perubahan perilaku siswa secara berkelanjutan. Penelitian ini merancang dan membangun sistem back-end website SEHATI (Sekolah Hijau dan Anti Plastik) sebagai aplikasi manajemen insentif ramah lingkungan yang melayani empat peran pengguna secara terstruktur. Sistem dikembangkan menggunakan framework NestJS berbasis Node.js, Supabase sebagai layanan basis data PostgreSQL, serta JSON Web Token (JWT) untuk autentikasi dan otorisasi pengguna, dengan metodologi Scrum dalam empat sprint. Fitur yang diimplementasikan mencakup sistem insentif berbasis poin dengan mekanisme streak kepatuhan membawa tumbler, pencatatan pelanggaran otomatis, transaksi kantin berbasis koin, voucher, dan leaderboard antar kelas. Pengujian menggunakan metode Black Box Testing melalui Swagger memvalidasi seluruh 136 endpoint API dan seluruhnya dinyatakan berfungsi dengan baik. Pengujian performa menunjukkan sistem mampu menangani 100 pengguna secara bersamaan dengan success rate 100% dan waktu respons P99 di bawah 100 ms pada kondisi beban tinggi. Sistem ini diharapkan menjadi solusi digital yang efektif dalam mendukung program Sekolah Hijau dan mendorong budaya peduli lingkungan melalui pendekatan gamifikasi di Sekolah Sukma Bangsa Pidie.

Sukma Bangsa Pidie School has implemented environmental regulations; however, a sanctions-based approach and manual record-keeping have not been able to drive sustainable changes in student behavior. This study designed and developed the SEHATI (Green and Plastic-Free School) website back-end system as an eco-friendly incentive management application that serves four user roles in a structured manner. The system was developed using the Node.js-based NestJS framework, Supabase as a PostgreSQL database service, and JSON Web Token (JWT) for user authentication and authorization, employing the Scrum methodology over four sprints. Implemented features include a point-based incentive system with a compliance streak mechanism for bringing reusable water bottles, automatic violation logging, canteen transactions using coins and vouchers, and an inter-class leaderboard. Testing using the Black Box Testing method via Swagger validated all 136 API endpoints, and all were found to function properly. Performance testing showed that the system is capable of handling 100 concurrent users with a 100% success rate and a P99 response time under 100 ms under high load conditions. This system is expected to be an effective digital solution in supporting the Green School program and promoting an environmentally conscious culture through a gamification approach at Sukma Bangsa Pidie School.
