Abstract
Permasalahan kesehatan gigi dan mulut mengakibatkan kehilangan gigi. Solusi yang bisa dilakukan dengan pemasangan implan gigi berbahan Ti6Al4V.Permasalahan keberhasilan terjadinya ikatan secara fungsional antara tulang rahang dengan permukaan implan menjadi faktor penting. Untuk meningkatkan keberhasilan ikatan fungsional perlu dilakukan modifikasi permukaan. Sehingga tujuan penelitian ini untuk memodifikasi permukaan Ti6Al4V dengan metode Plasma Electrolytic Oxidation (PEO). Kemudian untuk menganalisis pengaruh tegangan, media larutan dan waktu tahan terhadap lapisan yang terbentuk. Metode PEO dalam penelitian ini menggunakan variasi tegangan 425V, 450V dan 475V. Variasi media larutan dengan perbandingan komposisi Ca(CH3COO)2:KH2PO4:Na2EDTA yaitu 1:1:0,5;1,5:1:0,5;2:1:0,5 dalam satuan molar. Variasi waktu tahan 5 menit, 10 menit, 15 menit. Setelah dilakukan analisis dengan XRD (X-Ray Diffraction), morfologi permukaan lapisan dianalisis dengan uji SEM (Scanning Electron Mmicroscope) dan EDX (Energy Dispersive X-ray), sifat hidropilik lapisan dianalisis dengan uji sudut kontak air dan kekasaran permukaan dianalisis dengan alat surface roughness tester. Sampel terbaik pada tegangan 475V media larutan dengan ratio 2:1:0,5 dan waktu tahan 15 menit. Karena hasil uji XRD teridentifikasi hidroksiapatit terbanyak yaitu 76,2%. Morfologi permukaan secara kualitatif berdasarkan hasil uji SEM kekasaran meningkat karena secara kualitatif semakin besar aglomerasi hidroksiapatit. kekasaran dibuktikan dengan nilai Ra dan Rz yaitu 8,112µm dan 43,559µm dan sudut kontak terbentuk θkanan= 5,9350, θkiri= 5,8740. Sehingga lapisan yang terbentuk bersifat hidropilik

Dental and oral health problems result in tooth loss (edentolous). The solution use dental implans made from Ti6Al4V. The problem of successful functional bonding between the jawbone. The Implant surface is an important factor. To increase the success of functional bonding, it is necessary to modify the surface. So the purpose of this research is to modify the surface of Ti6Al4V with the plasma electrolytic oxidation (PEO) method. Then analyze the effect of voltage, solution media and holding time on layers formed. The PEO method in this study uses voltage variations of 425V,450V dan 475V. Variation of solution media with composition ratio of Ca(CH3COO)2:KH2PO4:Na2EDTA 1:1:0,5;1,5:1:0,5;2:1:0,5 in molar unit. Variations holding time 5 minutes, 10 minutes, 15 minutes. After analysis by XRD (X-Ray Diffraction), the surface morphology of the coating was analyzed by SEM (Scanning Electron Microscope) and EDX (Energy Dispersive X-ray)tests. The hidrophilic properties of the coating were analyzed by water contact angel test and the surface roughness was analyzed by surface roughness tester. The best sample at voltage of 475V solution media ratio 2:1:0,5 and holding time 15 minutes. Because the XRD test result identified the hydroxyapatite percentage is 76,2%. The surface morphology qualitatively based on result of the SEM test increase the roughness due to the greater agglomeration of hydroxyapatite. Roughness proven by Ra and Rz values are 8,112µm and 43,559µm. The contact angel formed formed θright = 5.9350, θleft = 5.8740. So that the layer formed is hydrophilic.
