      Abstract
      Benang jahit bedah merupakan biomaterial polimer yang lazim digunakan untuk menjahit jaringan pasca tindakan bedah. Tujuan utama penggunaan benang jahit bedah adalah menahan apposing jaringan bersama untuk memfasilitasi dan mempercepat proses penyembuhan dengan sedikit atau tanpa menimbulkan bekas luka. Seiring perkembangan zaman, dibutuhkan benang jahit dengan standar kualitas yang tinggi. Secara umum, benang operasi digolongkan menjadi dua jenis, yaitu benang yang dapat diserap (absorbable) dan yang tidak dapat diserap oleh tubuh (non-absorbable). Istilah “absorbable” mempunyai arti kemampuan untuk diabsorbsi (diserap), didegradasi (dipecah), baik sebagian atau seluruhnya oleh jaringan tubuh setelah diaplikasikan. Adapun beberapa hal yang perlu diperhatikan dalam aplikasi benang jahit bedah adalah kekuatan mekanik dan biokompatibilitas benang. Tujuan penelitian ini adalah melihat pengaruh penambahan biomaterial terhadap sifat fisiokimia dari benang bedah. Sifat fisiokimia yang diperhatikan dalam penelitian kali ini meliputi sifat mekanis, gugus fungsi menggunakan fourier transform infrared (FTIR), sifat termal menggunakan Thermogravimetry Analysis (TGA), dan morfologi permukaan scanning electron microcopy (SEM) sampel. Penambahan selulosa kedalam kolagen memiliki potensi terbesar dalam kenaikan kuat tarik sebesar sebesar 248%. Potensi terbesar kenaikan modulus young sebesar 157.14% dapat dicapai dengan menambahkan poliuretana. Peningkatan kuat tarik dan modulus young berdampak pada menurunnya elongasi dari sampel itu sendiri. Penambahan sutra memiliki pengaruh terbesar dalam peningkatan elongasi, yaitu 94.22%. Selain sifat mekanis, penambahan biomaterial juga mempengaruhi gugus fungsi dengan bergesernya bilangan gelombang atau hilangnya gugus fungsi. Perubahan sifat termal dan morfologi dari sampel menjadi indikasi adanya reaksi yang mempengaruhi sifat fisiokimia.
       
      Surgical suture threads are polymer biomaterials that are commonly used to suture tissue after surgery. The primary purpose of using surgical sutures is to hold the apposing tissue together to facilitate and speed up the healing process with little or no scarring. Along with the times, sewing threads with high quality standards are needed. In general, surgical sutures are classified into two types, namely those that can be absorbed (absorbable) and those that cannot be absorbed by the body (non-absorbable). The term "absorbable" means the ability to be absorbed (absorbed), degraded (broken down), either partially or completely by body tissues after being applied. Several things need to be considered in the application of surgical sutures, namely the mechanical strength and biocompatibility of the thread. The purpose of this study was to see the effect of adding biomaterials to the physiochemical properties of surgical sutures. Physiochemical properties that are considered in this research include mechanical properties, functional groups using Fourier transform infrared (FTIR), thermal properties using Thermogravimetry Analysis (TGA), and surface morphology of scanning electron microscopy (SEM) samples. The addition of cellulose to collagen has the greatest potential in increasing the tensile strength by 248%. The greatest potential for increasing the young’s modulus of 157.14% can be achieved by adding polyurethane. The increase in tensile strength and young’s modulus has an impact on decreasing the elongation of the sample itself. The addition of silk had the biggest effect in increasing the elongation, namely 94.22%. Apart from mechanical properties, the addition of biomaterials also affects functional groups by shifting the wavenumbers or the loss of functional groups. Changes in the thermal and morphological properties of the sample are an indication of a reaction that affects the physicochemical properties.
