Rice husks were a significant component of side product agriculture in the rice milling process. It is
a classic environmental problem as a source of agricultural waste. To utilize cellulose as a major component
in rice husk, there has been substantial study undertaken on the preparation of activated carbon as porous
materials. Studies of porous activated carbon (PAC) show the importance of the application of porous materials
such as adsorbents to remove environmental pollutants. This present research aimed to inquire the effect of
carbonization temperature (600, 700, 800, and 900oC) with HCl as chemical activated solution. The PAC
products were analyzed with the quality standard base on the national standard of Indonesia by number SNI
06-3730-1995. Analyzing the standard parameters of PAC were moisture content, ash content, volatile matter,
fixed carbon, and the amount of iodine absorption capacity have been studied. The PAC products were
characterized with FTIR and BET surface area analyzed to evaluate the porous of PAC. Returning to the initial
inquiry of this investigation, it is now possible to state that carbonization temperature is at 700oC. The higher
specific surface area (504,03 cm2/g), pore volume (0,258 nm), and micropore diameter (0,896 nm) have been
analyzed by multipoint BET method. Based on quality standards analyzed, the moisture content (0,67%) and
volatile matter (15,71%) to related for activated carbon from rice husk. A number of feasible future studies of
activated carbon from the natural source using the same experimental setup are evident
