Fabrikasi dan karakterisasi membran β-tcp dengan menggunakan serbuk β-tcp, natrium alginat, dan kalsium klorida
L Latar belakang: β-Tricalcium Phosphate (β-TCP) merupakan salah satu materialyang memiliki sifat osteokonduktif, bioaktif, dan biokompatibel sehinggaberpotensi digunakan sebagai filler pada membran untuk Guided BoneRegeneration (GBR). Penggunaan Natrium Alginat (NA), Kalsium Klorida (KK),dan β-TCP diharapkan dapat menghasilkan membran yang stabil dan efektif untukaplikasi regenerasi tulang. Tujuan: Untuk mengetahui karakteristik dan pengaruhvariasi konsentrasi β-TCP terhadap struktur kristal, gugus fungsi, dan morfologimembran yang difabrikasi. Metode: Penelitian eksperimental laboratoriumdeskriptif menggunakan campuran NA 2,5%, KK 1%, dan β-TCP dalam berbagaikonsentrasi (1%, 3%, 5%, dan 10%). Serbuk β-TCP difabrikasi denganmencampurkan kalsium karbonat (CaCO₃) dan Dibasic Calcium PhosphateDihydrate (DCPD) dengan rasio Ca/P 1,5 menggunakan ball mill, lalu dilakukanproses sintering pada suhu 1.100℃ selama 6 jam (kenaikan suhu 10℃/menit).Karakterisasi membran dilakukan menggunakan X-Ray Diffraction (XRD), FourierTransform Infrared (FTIR), dan Scanning Electron Microscopy (SEM). Hasil:Pengamatan visual menunjukkan bahwa membran semakin kasar seiringpenambahan konsentrasi β-TCP. Hasil XRD menunjukkan bahwa struktur kristalβ-TCP tetap terdeteksi dalam membran meskipun sudah difabrikasi bersama NAdan KK, dengan puncak difraksi yang sesuai dengan pola β-TCP murni.Karakterisasi FTIR mengidentifikasi gugus fosfat, hidroksil, dan karbonil sebagaiciri khas β-TCP. Analisis SEM menunjukkan bahwa konsentrasi β-TCPberpengaruh pada kekasaran permukaan akibat aglomerasi partikel sehinggaberpotensi mempengaruhi kualitas membran. Kesimpulan: Membran β-TCP yangdifabrikasi memiliki potensi untuk digunakan sebagai GBR.Kata kunci: β-Tricalcium Phosphate, natrium alginat, kalsium klorida, membran,Guided Bone Regeneration.
B Background: β-Tricalcium Phosphate (β-TCP) is a material with osteoconductive,bioactive, and biocompatible properties, making it a potential filler material formembranes used in Guided Bone Regeneration (GBR). The use of Sodium Alginate(SA), Calcium Chloride (CC), and β-TCP is expected to produce a stable andeffective membrane for bone regeneration applications. Objective: To investigatethe characteristics and effects of varying β-TCP concentrations on the crystalstructure, functional groups, and morphology of the fabricated membranes.Methods: A descriptive experimental laboratory study was conducted using amixture of 2.5% SA, 1% CC, and β-TCP in various concentrations (1%, 3%, 5%,and 10%). The β-TCP powder was fabricated by mixing calcium carbonate(CaCO₃) and Dibasic Calcium Phosphate Dihydrate (DCPD) with a Ca/P ratio of1.5 using a ball mill, followed by a sintering process at 1,100℃ for 6 hours(temperature increase of 10℃/minute). Membrane characterization was performedusing X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), and ScanningElectron Microscopy (SEM). Results: Visual observations showed that themembrane surface became rougher with increasing β-TCP concentration. XRDresults indicated that the β-TCP crystal structure remained detectable in themembrane even after fabrication with NA and KK, with diffraction peaks consistentwith pure β-TCP patterns. FTIR characterization identified phosphate, hydroxyl,and carbonyl groups as characteristic features of β-TCP. SEM analysisdemonstrated that β-TCP concentration affected surface roughness due to particleagglomeration, potentially influencing membrane quality. Conclusion: Thefabricated β-TCP membrane has potential for use as GBR.Keywords: β-Tricalcium Phosphate, sodium alginate, calcium chloride,membrane, Guided Bone Regeneration.
