      Abstract
      Biokomposit polivinil alkohol-hidroksiapatit-kitosan (PVA-HA-CH) merupakan material potensial untuk aplikasi medis. PVA bersifat biokompatibel dan biodegradabel. PVA dikombinasikan dengan sifat mekanik HA yang baik, serta CH yang memiliki sifat antimikroba menyediakan material sesuai untuk aplikasi balutan luka. Penelitian ini bertujuan menentukan komposisi biokomposit terbaik pada aplikasi balutan luka. Biokomposit PVA-HA-CH difabrikasi dengan teknik elektrospinning untuk menghasilkan nanofiber. Pada penelitian ini, enam larutan PVA-HA-CH disiapkan dengan konsentrasi HA dan CH yang berbeda. Karakteristik struktural, fisik, dan biomedis dari komposit nanofiber yang dihasilkan dilakukan pengujian menggunakan Optical Microscope (OM), Scanning Electron Microscope (SEM), X-Ray Fluorescence (XRF), uji kuat tarik, dan uji sudut kontak. Berdasarkan analisis SEM dan hasil uji tarik, PVA-HA-CH dengan konsentrasi HA (2% w/v) dan CH (2% w/v) dipilih untuk studi in-vitro. Bioaktivitas PVA dan komposit dievaluasi melalui perendaman dalam larutan simulated body fluid (SBF) dan uji viabilitas sel. Hasil penelitian menunjukkan, penambahan HA dan CH meningkatkan sifat mekanis dan aktivitas biologis PVA. Evaluasi biokompatibilitas, tidak terjadi sitotoksisitas signifikan dari komposit nanofiber PVA-HA(2%)-CH2%). Komposit nanofiber PVA-HA(2%)-CH2%) berpotensi dikembangkan sebagai balutan luka potensial yang mendukung proses penyembuhan luka. Kata kunci: Balutan luka, elektrospinning, hidroksiapatit, kitosan, nanofibers
       
      Polyvinyl alcohol-hydroxyapatite-chitosan (PVA-HA-CH) bio-composite is a potential material for medical application. The biocompatible and biodegradable PVA that is combined with good mechanical properties of HA and antimicrobial of CH provides a suitable material for wound dressing application., The objective of this study was to determine the best bio-composite composition for wound dressing application. The PVA-HA-CH bio-composites were fabricated by electrospinning technique to produce nanofiber. In this study, six PVA-HA-CH solutions were prepared with different concentrations of HA and CH. The structural, physical, and biomedical characteristics of the prepared nanofibrous dressing material were investigated by Optical Microscope (OM), Scanning Electron Microscope (SEM), X-Ray Fluorescence (XRF), tensile test, and contact angle test. Based on SEM analysis and tensile test results, PVA-HA-CH in concentration HA(2%w/v) and CH(2%w/v) was chosen for In-vitro studies. The bioactivity of the PVA and the composites were evaluated by simulated body fluid and viability test. The results showed that the addition of HA and CH increases the mechanical properties and biological activity of PVA. Biocompatibility evaluation showed no significant cytotoxicity of PVA-HA(2%)-CH2%) composite. Composite nanofiber PVA-HA(2%)-CH2%) may have potential applications in trauma healing and wound dressing. Keywords: Chitosan, electrospinning, hydroxyapatite, nanofibers, wound dressing
