Abstract

Porous tantalum has been recently recognized as a conventional orthopedic implant for bone substitute applications besides stainless steel, cobalt-chromium, titanium, and other metallic alloys. Porous tantalum has excellent mechanical and osseointegration properties similar to cancellous bone structure. To optimize the utilization, the dip coating technique was applied to coat porous tantalum with hydroxyapatite (HA). X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques investigate the coating characterization. HA is a bioceramic material that used for bone substitutes due to its chemical and structural similarity to bone minerals. Coated porous tantalum requires the sintering process of porous tantalum to adhere to HA. During the sintering process, various temperatures (650°C, 750°C, 850°C, 950°C, and 1100°C) were used to determine the optimum temperature for porous tantalum coated with HA. The heating rate is 1°C/1 min and the holding time is 60 minutes. The result shows that the optimum temperature of HA-coated porous tantalum is at 850°C. The morphology structure of the HA-coated porous tantalum shows that the adhesion between porous tantalum and HA is in good condition. The element in the HA-coated porous tantalum shows that the existence of HA is high.

Abstract

Tepung porang diperoleh dari proses pengeringan dan pengayakan umbi porang, yang mana memiliki kadar glukomanan yang tinggi. Glukomanan merupakan serat pangan larut air yang mengandung kalori yang rendah dan banyak digunakan sebagai bahan pengental dalam industri pangan. Salah satu proses pengolahan porang menjadi glukomanan diantaranya adalah pengayakan rotary screen, yaitu suatu proses pemisahan bahan berdasarkan ukuran lubang kawat atau mesh yang terdapat pada ayakan yang berputar. Tulisan ini bertujuan untuk menganalisis pengaruh sudut kemiringan dan kecepatan putaran ayakan terhadap kinerja mesin rotary screen dan menentukan kondisi terbaik mesin rotary screen dalam pemisahan glukomanan tepung porang. Mesin pemisah yang digunakan jenis rotary screen dengan dua jenis ukuran mesh. Sudut kemiringan yang digunakan 5°, 10°, dan 15°, kecepatan putaran ayakan divariasikan pada 30 rpm, 40 rpm,dan 50 rpm. Desain penelitian yang dipilih untuk dua faktor dan dua level adalah full factorial, dimana massa input awal tepung porang sebanyak 1 kg. Hasil analisis ANOVA menunjukkan bahwa kedua parameter, baik sudut kemiringan ataupun kecepatan putaran berpengaruh secara signifikan terhadap massa glukomanan dengan nilai P-value sebesar 0,03, sedangkan kecepatan putaran ayakan sebesar 0,017. Berdasarkan hasil respon parameter terbaik diperoleh bahwa variasi sudut kemiringan 5° dan kecepatan putaran ayakan 30 rpm memberikan hasil terbesar dengan rendemen glukomanan sebesar 340 gram.
