Abstract
Material yang memiliki sifat antimikroba telah banyak digunakan sebagai bahan pelapis untuk mengurangi keberadaan bakteri patogen pada permukaan benda yang sering disentuh. Tujuan dari penelitian ini adalah untuk menganalisis karakteristik nanopartikel tembaga sebagai senyawa aditif pada cat pelapis dan mengevaluasi aktivitas antibakterinya. Sintesis nanopartikel tembaga (Cu) dilakukan melalui metode reduksi kimia menggunakan glukosa dan asam askorbat sebagai reduktor. Sifat nanopartikel tembaga yang kurang stabil dan mudah teroksidasi, mengakibatkan material ini membutuhkan capping agent seperti etilen glikol (Cu-EG). Karakterisasi material dilakukan menggunakan X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) - Energy Dispersive X-Ray (EDX), Transmission Electron Microscope (TEM), serta Particle Size Analyzer (PSA). Nanopartikel Cu dan Cu-EG yang telah disintesis digunakan sebagai zat aditif pada cat pelapis dengan variasi konsentrasi aditif sebesar 1% (b/b), 5% (b/b), 10% (b/b), dan 15% (b/b). Aktivitas antibakteri dievaluasi menggunakan metode difusi cakram Kirby-Bauer terhadap bakteri Escherichia coli dan Staphylococcus aureus. Cat pelapis dengan aditif Cu dan Cu-EG memiliki aktivitas antibakteri yang semakin besar seiring dengan bertambahnya konsentrasi yang diberikan. Pelapis antimikroba ini dapat digunakan sebagai komponen utama untuk strategi mitigasi dari infeksi bakteri karena adanya aktivitas contact-killing terhadap bakteri patogen.

Materials with bioactive properties has been widely used as antimicrobial coatings to reduce the presence of pathogenic bacteria on frequently touched surfaces. The aim of this experiment is to analyze characteristic copper nanoparticle as additive compound for coating paint and evaluate their antibacterial activity. Synthesis of copper (Cu) nanoparticles was carried out through a chemical reduction method using glucose and ascorbic acid as reducing agents. Characteristic of copper nanoparticle is less stable and easily oxidized, resulting this material requiring a capping agent such as ethylene glycol (Cu-EG). Material characterization using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray (EDX), Transmission Electron Microscope (TEM), and Particle Size Analyzer (PSA). Cu and Cu-EG are used as additives in coating paints with variations in additive concentrations of 1% (w/w), 5% (w/w), 10% (w/w), and 15% (w/w). b). The antibacterial activity of antimicrobial coating was determined by Kirby-Bauer disk diffusion method against Escherichia coli and Staphylococcus aureus. Coating paints with Cu and Cu-EG additives have antibacterial activity which increases with increasing concentration. This antimicrobial coating can be used as the main component for the mitigation strategy of bacterial infection because of its contact-killing activity against pathogenic bacteria.
