Abstract

Paduan magnesium salah satu material yang dapat diaplikasikan pada biomaterial implant, namun memiliki kekurangan yaitu nilai laju degradasi yang cukup tinggi sehingga dibutuhkan pelapisan logam dengan metode Plasma Electrolytic Oxidation (PEO). Pada penelitian ini digunakan tricalcium phosphate (TCP) dengan alginate sebagai post treatment. Dalam penelitian ini, variasi penambahan massa TCP yang digunakan adalah 5 g/l, 7,5 g/l, dan 10 g/l. Variasi penambahan massa alginat yang digunakan adalah 5 g/l, 10 g/l, dan 15 g/l yang dilarutkan dalam aquadest untuk proses dip coating. Dari hasil data morfologi yang di dapatkan, variasi yang menghasilkan pori terkecil yaitu pada TCP 10 g/l sebesar 0,348 µm. Kemudian variasi massa alginate 15 g/l menghasilkan pori tekecil sebesar 0,073 µm dan ketebalan terkecil di dapatkan pada variasi massa alginate 15 g/l sebesar 28,013 µm. Kemudian dilakukkan pengukuran laju degradasi dengan metode weight loss dan polarisasi. Hasil uji weight loss variasi massa alginate 15 g/l memiliki laju degradasi yang paling lambat sebesar 0,31 mpy, laju degradasi ini menurun signifikan dibandingkan dengan AZ31B tanpa perlakuan sebesar 14,87 mpy dan AZ31B dengan PEO TCP 10 g/l sebesar 13,09 mpy. Kemudian hasil uji polarisasi variasi massa alginate 15 g/l memiliki laju degradasi yang paling lambat sebesar 0,60 mpy, laju degradasi ini menurun signifikan dibandingkan dengan AZ31B tanpa perlakuan yang laju degradasi nya sebesar 27,52 mpy dan AZ31B dengan PEO TCP 10 g/l sebesar 15,92 mpy. ====================================================================================================== Magnesium alloy is one of the materials that can be applied to implant biomaterials, but it has a disadvantage, namely the value of the degradation rate, which is high enough so, metal coating is needed with the Plasma Electrolytic Oxidation (PEO) method. In this study, tricalcium phosphate (TCP) was used with alginate as post-treatment. In this study, the variations in the mass addition of TCP used to be 5 g/l, 7.5 g/l, and 10 g/l. Variations in the addition of alginate mass used were 5 g/l, 10 g/l, and 15 g/l dissolved in aquadest for the dip coating process. From the results of the morphological data obtained, the variation that produced the smallest pore was the TCP 10 g/l at 0.348 µm. Then the alginate mass variation of 15 g/l resulted in a small pore of 0.073 µm and the smallest thickness was obtained in the alginate mass variation of 15 g/l of 28.013 µm. Then, the rate of degradation was measured using the weight loss and polarization methods. The results of the weight loss test of 15 g/l alginate mass variation had the slowest degradation rate of 0.31 mpy, this degradation rate decreased significantly compared to AZ31B without treatment at 14.87 mpy and AZ31B with PEO tricalcium phosphate 10 g/l by 13.09 mpy. Then the results of the mass variation polarization test of alginate 15 g/l had the slowest degradation rate of 0.60 mpy, this degradation rate decreased significantly compared to AZ31B without treatment which had a degradation rate of 27.52 mpy and AZ31B with PEO tricalcium phosphate 10 g/l is 15.92 mpy.
