      "rev_number": 17,
      "abstract": "Sektor e-commerce di Indonesia mengalami pertumbuhan pesat yang \r\ndisertai dengan peningkatan risiko keamanan data yang signifikan. Ancaman\r\nutama tidak hanya datang dari pihak eksternal, tetapi juga dari manipulasi data\r\ntransaksi oleh pihak internal yang memiliki akses penuh terhadap basis data.\r\nSistem basis data konvensional yang bersifat dapat diubah tidak mampu menjamin\r\nintegritas riwayat status pesanan, sehingga menyebabkan hilangnya kepercayaan\r\nkonsumen terhadap transparansi proses pengiriman dan membuka celah bagi\r\npenyalahgunaan wewenang oleh administrator sistem. \r\n \r\nPenelitian ini bertujuan untuk merancang bangun sistem pencatatan \r\ntransaksi yang aman dan transparan pada platform e-commerce \"BelanjaTech\".\r\nMetode penyelesaian masalah yang diterapkan adalah implementasi mekanisme\r\nhash chaining menggunakan algoritma kriptografi SHA-256 pada arsitektur\r\nsistem berbasis web. Sistem dikembangkan dengan pendekatan Prototype\r\nmenggunakan kerangka kerja Next.js dan basis data PostgreSQL. Logika\r\nkeamanan diterapkan pada sisi backend API untuk secara otomatis menghasilkan\r\nblok hash baru setiap kali terjadi pembaruan status pesanan, menciptakan jejak\r\naudit yang saling terikat layaknya rantai blockchain. \r\n \r\nHasil penelitian menunjukkan bahwa sistem yang dibangun mampu \r\nmenciptakan immutable ledger yang efektif. Pengujian Black Box membuktikan\r\nbahwa mekanisme validasi integritas data berhasil mendeteksi upaya manipulasi\r\nilegal secara real-time dengan memunculkan peringatan keamanan pada\r\nantarmuka pengguna saat terjadi ketidakcocokan antara data basis data dan data\r\nhash. Penelitian ini memberikan kontribusi solusi teknis bagi pelaku industri ecommerce\r\n\r\nskala menengah untuk meningkatkan standar keamanan data dan\r\nkepercayaan pelanggan tanpa memerlukan infrastruktur blockchain publik yang\r\nmahal.",
