Abstract

Penelitian ini bertujuan untuk menganalisis dan mengimplementasikan teknologi blockchain dalam sistem infonnasi kesehatan sebagai solusi untuk meningkatkan keamanan, integritas, dan kerahasiaan data pasien. Permasalahan utama yang dihadapi pada sistem tradisional meliputi kerentanan terhadap peretasan, manipulasi data, serta kurangnya transparansi dalam proses pertukaran infonnasi medis antar lembaga. Metode penelitian menggunakan pendekatan studi literatur, analisis kebutuhan sistem, dan simulasi implementasi blockchain berbasis mekanisme konsensus Proof-of-Authority. Pengujian dilakukan melalui evaluasi keamanan, kecepatan transaksi, serta ketahanan sistem terhadap serangan umum seperti pen-Ibahan data tanpa otorisasi dan pencurian identitas. Hasil penelitian menunjukkan bahwa blockchain mampu meningkatkan keamanan data pasien secara signifikan melalui mekanisme pencatatan terdistribusi, enkripsi kriptografi, serta kontrol akses berbasis smart contract. Selain itu, sistem menunjukkan peningkatan integritas data dan transparansi alur informasi tanpa mengorbankan kinerja. Simpulan dari penelitian ini adalah bahwa blockchain merupakan teknologi yang efektif dan layak diterapkan dalam sistem infonnasi kesehatan, dengan potensi besar untuk menjadi standar keamanan data di masa depan, meskipun masih memerlukan optimalisasi terkait skalabilitas dan interoperabilitas antar platform medis. Kata Kunci : Blockchain, Sistem Informasi Kesehatan, Keamanan Data, Smart Contract, Integritas Data, Proof-of- Authority ================================================================================================== This study aims to analyze and implement blockchain technology in health information systems as a solution to enhance the security, integrity, and confidentiality of patient data. Traditional systems often face vulnerabilities such as hacking attempts, data manipulation, and limited transparency in medical information exchange across institutions. The research employs a literature review, system requirements analysis, and a simulation of blockchain implementation using a Proof-of-Authority consensus mechanism. System testing includes security evaluation, transaction speed measurement, and resilience assessments against common threats such as unauthorized data modification and identity theft. The results indicate that blockchain implementation significantly improves the security of patient data through distributed ledger mechanisms, cryptographic enczyption, and smart contract—based access control. Additionally, the system demonstrates improved data integrity and transparency without compromising performance. The study concludes that blockchain is an effective and feasible technology for health information systems, with strong potential to become a future standard for data security, although further optimization is needed in terms of scalability and interoperability across medical platforms.
