Extraction of natural dye leaves & flowers to dope on metal oxide / Nur Liana Syuhada Noor Hishamsuri

The combination of post covid recovery, depleted fossil fuel reverse and extreme weather conditions led to surge in demand for energy. Solar energy is a sustainable industry that captures the interest of the energy industry in the world. The material that is most used nowadays is from synthetic dye. Therefore, natural dye from the plant is proposed. This is because the natural never pollutes like synthetic dye as they are obtained. The objective of this study is to find out the best extraction time of natural dye in metal oxide. The natural dye was extracted from Pandanus Amaryllifolius (leaf) using conventional extraction method and doped into metal oxide which is Calcium Oxide (CaO) for 6 to 8 days. The result obtained showed the concentration of dye increasing as the time extract is increased. The natural dye is also tested with conductivity and the result showed a decreasing trend. To conclude, natural dye has the potential to be used for the solar film material.
