The paper report antibacterial activity of flower extract from Pinus merkusii Jungh Et De Vriese and its mixture with copper nanoparticle on Staphylococcus aureus. This finding revealed the potency of pine forestry waste to overcome a bacterial-resistance problem on some commercially antibiotics. The extract was prepared by hot water extraction of a dried powder of pine flower. Copper nanoparticle was synthesized following "green synthesis technique" using phenolic-rich extract of pine's flower as a reduction and capping agent. In short, a mixture of pine's flower extract and copper nanoparticle importantly was able to inhibit the growth of Staphylococcus aureus four times higher than that using water extract. © Published under licence by IOP Publishing Ltd.
