6. Research Method• Research is experimental in nature is a form of experimental research that seeks to isolate and control any conditions relevant to a situation that was examined and then do the observation of the effect or influence potential extraction of moringa oleifera as a source of energy. • With the changes or manipulation of free variables the number of materials used and its effects observed at variable voltage and electric current is generated as a source • The influence of the application of additional ingredients such as (quasi experiment of acid and salt and water on the circuit generates the voltage and electric current).• Extraction is a process of separation of a substance based on the difference in solubility of two not mutually soluble liquids, usually water and other organic solvents.• The extraction process can take place at the liquid-liquid extraction, also known by the name solven extraction. This type of extraction is a process commonly used in laboratory scale or industrial scale.• Leaching of chemical separation process, which aims to separate a chemical compound from the matrix solids into liquids
