Objektif kajian ini adalah untuk merawat kulit dengan nanopartikel perak untuk membangunkan ciri-ciri antibakteria di kulit. Aktiviti biologi ke atas kasut kulit menyebabkan pertumbuhan bakteria dan menyebabkan bau yang tidak menyenangkan. Nanopartikel perak telah diketahui mempunyai beberapa kesan antibakteria dan telah ditambah kepada minyak yang digunakan dalam langkah pemprosesan kulit. Sedikit nanopartikel perak (6 dan 8%v/v) telah dimasukkan ke dalam minyak dan ciri-ciri antibakteria telah dinilai menggunakan rendaman dan kaedah ujian kapasiti. Larutan bakteria, bersamaan kekeruhan McFarland piawai sebanyak 0.5 telah disediakan untuk staphylococcus aureus dan bakteria Escherichia coli. Hasil kajian menunjukkan bahawa ujian antimikrobial ke atas sampel yang mengandungi nanopartikel perak menunjukkan ciri-ciri antibakteria yang indikasi oleh Piawai Antarabangsa (ISO 22196) kelembutan penggantungan kurang dari 3x108 CFU/ml. Oleh itu kulit yang dirawat dengan nanopartikel perak mempunyai ciri-ciri antibakteria dengan kecenderungan untuk mengurangkan bau-bau tidak menyenangkan. Kata kunci: Kulit; sifat anti-bakteria; nanopartikel; perak The objective of this study is to treat leather with silver nanoparticles so as to develop antibacterial properties in the leather. The biological activity on leather shoes resulted in bacterial growth and caused the unpleasant smell. Silver nanoparticles have been known to possess some antibacterial effects and were added to the oil used in the leather processing step. A small amount of silver nanoparticles (6 and 8%v/v) were added to oil and its antibacterial properties have been evaluated using the immersion and capacity test methods. The bacteria suspension, a turbidity equivalent to a 0.5 McFarland standard was prepared for the S. aureus and E. coli bacteria. Results revealed that antimicrobial tests on samples containing silver nanoparticles showed suitable antibacterial properties indicated by the International Standard (ISO 22196) tenderness of suspension of less than 3x108 CFU/ml. Thus leather treated with silver nanoparticles has antibacterial properties with the tendency to reduce the unpleasant odors.
