Abstrak

Dalam beberapa tahun terakhir, adopsi Rekam Medis Elektronik (RME) telah menjadi bagian penting dari transformasi digital di sektor kesehatan. Namun, sistem RME yang bersifat terpusat masih menghadapi sejumlah tantangan, seperti risiko single point of failure dan keterbatasan dalam menjamin integritas serta keamanan data pasien. Penelitian ini bertujuan untuk mengembangkan purwarupa sistem penyimpanan data RME yang terdesentralisasi dengan memanfaatkan teknologi Blockchain dan Inter-Planetary File System (IPFS). Sistem dirancang untuk mendukung tiga skenario utama, yaitu pendaftaran pasien, pencarian data pasien, dan pendaftaran rawat jalan. Data rekam medis pasien disimpan secara off-chain pada IPFS dalam format JSON, sementara metadata berupa Content Identifier (CID) dan Nomor Induk Kependudukan (NIK) disimpan secara on-chain pada jaringan Ethereum menggunakan Smart Contract. Evaluasi sistem dilakukan melalui pengujian non-fungsional dengan mengukur konsumsi gas used pada fungsi penyimpanan data pasien dan pendaftaran rawat jalan. Hasil pengujian menunjukkan bahwa fungsi penyimpanan data pasien memiliki rata-rata penggunaan gas sebesar 380.907 unit, jauh lebih tinggi dibandingkan fungsi pendaftaran rawat jalan sebesar 51.540 unit, yang mencerminkan tingkat kompleksitas proses yang lebih besar. Temuan ini sekaligus menunjukkan bahwa integrasi teknologi blockchain dan IPFS berpotensi digunakan sebagai solusi penyimpanan Rekam Medis Elektronik (RME) yang aman dan terdesentralisasi.
