Sintesis dan Karakterisasi Fluorapatit dengan Variasi Suhu Sintering Berbasis Cangkang Keong Sawah Menggunakan Metode Presipitasi

Abstract

Kerusakan pada gigi merupakan salah satu contoh kurangnya unsur kalsium pada tubuh kita, karena kalsium berperan dalam perkembangan tulang dan gigi. Cangkang keong sawah dapat digunakan sebagai prekursor untuk pembentukan fluorapatit (FAp). Penelitian ini bertujuan menyintesis dan mengkarakterisasi FAp dari cangkang keong sawah dengan metode presipitasi serta mengetahui pengaruh variasi suhu sintering. Metode penelitian ini dilakukan melalui tahapan preparasi cangkang keong sawah, Sintesis FAp dengan variasi suhu sintering (600 °C, 800 °C, dan 1000 °C) dengan metode presipitasi. Hasil sintesis FAp dikarakterisasi dengan X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) serta Scanning Electron Microscope Energy Dispersive X-Ray (SEM-EDX). Hasil penelitian menunjukkan bahwa fluorapatit yang disintering dengan suhu 1000 °C memiliki nilai kristalinitas yang paling tinggi berdasarkan hasil XRD. Spektrum FTIR dari FAp suhu 1000 °C diidentifikasi memiliki gugus -OH, OH-F, dan -PO43-. Hasil analisis SEM-EDX menunjukkan fluorapatit dengan suhu 1000 °C memiliki bentuk seperti batang dan jarum serta memiliki rasio molaritas Ca/P sebesar 13,18 dan P/F sebesar 4,29.

Synthesis and Characterization of Fluorapatite with Variations in Sintering Temperature Based on Rice Snail Shells Using the Precipitation Method. Supervised by IRMA HERAWATI SUPARTO and CHARLENA Tooth decay is an example of a lack of calcium in our bodies, because calcium plays a role in the development of bones and teeth. Rice snail shells can be used as a precursor for forming fluorapatite (FAp). This study aims to synthesize and characterize FAp from rice field snail shells using the precipitation method and to determine the effect of variations in sintering temperature. This research method was carried out through the stages of preparation of rice snail shells, FAp synthesis with various sintering temperatures (600 °C, 800 °C, and 1000 °C) with the precipitation method. The results of the FAp synthesis were characterized by X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) and Scanning Electron Microscope Energy Dispersive X-Ray (SEM-EDX). The results showed that fluorapatite sintered at 1000 °C had the highest crystallinity value based on XRD results. The FTIR spectrum of FAp at 1000 °C was identified as having -OH, OH-F, and -PO43- groups. The results of SEM-EDX analysis showed that fluorapatite at a temperature of 1000 °C had a shape like rods and needles and had a Ca/P molarity ratio of 13.18 and P/F of 4.29.
