Abstract

Severe effects of the mercury use on health as an amalgam material have required an alternative material in order to eliminate it from amalgam composition. This research was conducted to analyze the physical properties and compressibility of ZnO nanopowder as an alternative amalgam material. The physical properties including morphology, dimensions, and the atomic ratio were analyzed by SEM, XRD-XRF and EDX. Further, the compressibility was conducted by using hydraulic press machine. The results showed that ZnO has particle size of 14.34 nm with morphology classified as nanorods. In the compressibility test, both the variation of compression loadings and holding time have brought an effect on the significant increase of ZnO nanopowder density.

Abstract

In this study, the application of nanotechnology was applied in the dentistry field, especially in the innovation of dental amalgam material. To date, mercury (Hg) has been used widely as dental amalgam material with consideration of the cheap price, ease of use, and good mechanical strength. However, last few years, many problems have been faced in the dentistry field due to the use of mercury. Hence, new material is needed as an innovation to eliminate the mercury from dental amalgam composition. This research was conducted to analyze the physical properties and compressive strength of zinc oxide (ZnO) nanopowder as a potential dental amalgam material. The physical properties such as morphology and dimensions were analyzed by SEM and XRD. Further, the compression test was conducted by using hydraulic press machine. The results showed that the ZnO nanopowder analyzed has the particle size of 14.34 nm with the morphology classified as nanorods type. On the compression load of 500 kg, the average of ZnO green density is 3.170 g/cm3. This value experienced the increase of 4.763% when the load was set to 1000 kg, and 7.539% at 2000 kg. The dwelling time also took the same effect. At 30 seconds, the average of ZnO green density is 3.260 g/cm3. This value experienced the increase of 0.583% at 60 seconds and 3.098% at 90 seconds.

Abstract

Sand Casting atau cetakan pasir merupakan suatu cetakan yang umum digunakan  pada teknik pengecoran logam. Kaolin merupakan masa batuan yang tersusun dari material lempung berwarna putih atau krem. Tujuan penelitian ini adalah untuk mengetahui pengaruh campuran kaolin terhadap sifat mekanik dan permeabilitas pada kondisi pasir basah dan kering. Metode yang digunakan dalam penelitian ini adalah experimental dengan pendekatan deskriptif. Bahan campuran kaolin dibuat bervariasi sebesar 1% ,4%, 7%, 10%, dan 13%. Temuan penelitian yang didapatkan yaitu: (1) kekautan tarik tertinggi terdapat pada variasi kaolin 13% yaitu sebesar 0,07 Kg/cm2, (2) kekuatan tekan tertinggi terdapat pada variasi kaolin 13% sebesar 3,11 Kg/cm2, (4) kekuatan geser tertinggi terdapat pada vaiasi kaolin 7% sebesar 0,46Kg/cm2,  (5) permeabilitas tertinggi terdapat pada variasi kaolin 10% sebesar 230 ml/menit, (6) variasi 1% dan 4% tidak dapat digunakan karena pada saat pembuatan spesimen atau sampel terjadi ambrol atau hancur.
