Heavy Metal Analysis of Java Tea Herbs Planted Directly Under Solar PV Arrays in the Tropics
The increasing demand of potential high value herbal crops and solar Photovoltaic (PV) technologies especially in Malaysia creates a green economic opportunity for the unique integration of agriculture and Renewable Energy Resources (RER). The adaptation of solar PV technologies in high value herbal crops cultivation for tropical country like Malaysia, requires in-depth research work where in this study, the Java Tea herbal plant (Orthosiphon Stamineus) are planted directly under Solar Photovoltaic array structures in the PV Pilot Plant Universiti Putra Malaysia. Although Java Tea has been proven to be physiologically sustainable under this condition, the crucial factor still remains is the radiation effect discharges from the energy conversion process throughout the plant growth. Thus, this work looks at the primarily clinical study based on the Heavy Metal compounds (5 parameter test), Protein and Crude Fiber content in the sample. The test conducted is based on the requirements from the National Pharmaceutical Control Bureau (NPCB) of Malaysia as the baseline for food supplements. The results shows that the Java Tea-PV product is safely consumable with good protein content of 8.4 g/100g, 30.1% w/w Crude Fibre and only Lead detection of 0.5 mg/kg.
