Abstract

Penelitian tentang sintesis komposit kitosan/MgO/Ag dengan variasi massa prekursor AgNO3 0,05 g, 0,1 g, 0,15 g dan 0,2 g disintesis dengan metode kopresipitasi. Komposit yang dihasilkan dikarakterisasi menggunakan X-Ray Diffractometry (XRD) dan Scanning Electron Microscope (SEM). Selanjutnya, keefektifan komposit ini sebagai antibakteri diuji yaitu Staphylococcus aureus (Gram positif) dan Escherichia coli (Gram negatif). Hasil penelitian menunjukkan bahwa puncak karakteristik partikel MgO dan Ag tidak muncul pada difraktogram XRD, tetapi secara visual dan morfologis SEM mendukung pembentukan dua partikel dan berdasarkan literatur dari hasil peneliti lain. Selain itu, komposit ini efektif dalam menghambat pertumbuhan kedua bakteri.

Furthermore, the effectiveness of this composite as an antibacterial was tested, namely Staphylococcus aureus (Gram positive) and Escherichia coli (Gram negative). The results showed that the characteristic peaks of MgO and Ag particles did not appear on the XRD diffractogram, but visually and morphologically SEM supported the formation of two particles and based on the literature from the results of other researchers. In addition, this composite is effective in inhibiting the growth of both bacteria.

KITOSAN/MgO/Ag合成复合材料，并对抗菌作用进行分析

该研究采用抑制法合成的基托山/MgO/Ag前体质量变异。生产的复合材料采用x光衍射(XRD)和扫描电子显微镜(SEM)进行分类。此外，这些作为抗菌药物的复合材料的有效性被测试为菌根菌根(正克)和大肠杆菌(阴性克)。研究结果表明，MgO和Ag粒子的峰值并没有出现在XRD的衍射图中，而是在视觉和形态学上支持两种粒子的形成，并基于其他研究人员的研究结果。此外，这种复合材料有效抑制了两种细菌的生长。抽象研究的吉山/MgO/Ag合成了0.05 g、0.1 g、0.15 g和0.2 g是由采用精确性方法合成的。用x光衍射和扫描电子显微镜(SEM)进行分析。此外，这种抗菌药物的有效性受到了测试，namely stalococcus aurecus和Escherichia大肠杆菌(阴性克)。最近的结果表明，MgO和Ag particles的性格特征并没有出现在XRD difftogram上，而是形形色色和形态上支持两党的形成，并基于其他观察结果的文献。此外，这个合成物质有效地抑制了两种细菌的生长。
