Activated carbon demand in the world each year increased by approximately 5% per year, estimated that the demand of activated carbon of about 1.2 million tons in 2010. Therefore many efforts carried out research into alternative materials that could be used as raw material for making activated carbon. Muallifah research shows that activated carbon from Moringa seeds can be used to purify used frying oil, but the activated carbon used Moringa seeds have not completed the characterization of activated carbon according to data Indonesian Industrial Standard (SII), the research on the characterization of activated carbon from Moringa oleifera seed needs to be done. In this research study will be conducted on the effect of NaCl concentration on the process of carbonization of the characterization of activated carbon and the influence of physical activation of the characterization of activated carbon. The process of making activated carbon through the three stages of Moringa oleifera seed dehydration at 105 ° C for 24 hours, then oleifera seed soaking in a solution of NaCl 15%, 20%, 25%, 30%, 35%, and 40% for five hours, the process karboniasi at 500 º C for 120 minutes and the activated carbon in the sifter M. oleifera 120-250 mesh and then activated with physics at a temperature 650 º C in the medium of nitrogen for 120 minutes. The characterization was conducted on the specific gravity, iodine number, water content and ash content of activated carbon. The results showed variation of NaCl concentration and activation of physics affect the results of characterization of activated carbon based on the results of statistical analysis, F test and LSD 1% continued using the program Minitab 14 known different (significance <0.01). Activated carbon is through immersion NaCl 30% with activation of physics have the best characteristics of the iodine number 646 mg / g, density of 0.8917 g of activated carbon / mL, the water content of 1% and 5.8% ash content.
