Kerusakan patah tulang pada manusia dapat diperbaiki dengan bantuan implan, contohnya menggunakan paduan titanium Ti-6Mo-6Nb. Namun, paduan tersebut memiliki keterbatasan sifat kelembaman biologi dan ketahanan korosi saat diaplikasikan sebagai implan ortopedi dengan menimbulkan risiko infeksi. Solusi untuk mengatasi hal ini, paduan Ti-6Mo-6Nb dilakukan modifikasi permukaan dengan menggunakan proses pelapisan hidrotermal pada kombinasi campuran material pelapis seperti kitosan, kaca bioaktif, dan seng oksida. Penelitian ini difokuskan dalam pengaruh penambahan rasio seng oksida sebanyak 0, 1 dan 3 dengan pengunaan variasi waktu perendaman selama 1 ,2 dan 3 jam terhadap sifat antibakteri dan ketahanan korosi. Metode penelitian yang digunakan, yaitu preparasi sampel paduan Ti-6Mo-6Nb, sintesis larutan pelapis, proses pelapisan hidrotermal, karakterisasi morfologi permukaan (SEM-EDX), karakterisasi gugus fungsi atau interaksi ikatan kimia (FTIR), karakterisasi kekasaran permukaan (3D OM), karakterisasi pembasahan permukaan (Contact Angle), pengujian sifat antibakteri, dan pengujian korosi. Hasil penelitian menunjukkan bahwa paduan Ti-6Mo-6Nb yang dilapisi oleh material pelapis dengan kode sampel Z0-2J diperoleh nilai laju antibakteri tertinggi sebesar 65%, maka mengindikasikan mempunyai sifat antibakteri yang baik dan pada kode sampel Z3-3J diperoleh nilai laju korosi terendah, yaitu 1,6E-04 mm/tahun dengan nilai resistansi tertinggi sebesar 2857,5 kΩ, sehingga memiliki sifat ketahanan korosi yang baik. date: 2026-04-02 date_type: published pages: 149 institution: Fakultas Teknik Universitas Sultan Ageng Tirtayasa department: Teknik Metalurgi thesis_type: sarjana thesis_name: sarjana referencetext: [1] W.
