Abstract One of the activities in PT International Nickel Indonesia Tbk release SOx. The gas is very harmful to human as well as natural ecosystem. It is recommended that the gas should be reduced. One of the efforts is planting trees which have very high absorption ability. The objective of the research is to identify absorption ability of several trees found in the mining area. All leaves of 3 branches of certain species were collected, put in plastic bags and soaked in alcohol for about 1 hour. The leaves of all species then put in paper bags and put in oven of 60oC for 1 night. The dried leaves then grind to get material powder and then sent to laboratory to analyze the sulfur content. The research revealed that sulfur content of leaves were varied depend on species and locations. It is assumed that the variation caused by absorption ability of plants species. It was noticed that there are 19 sample species which have high sulfur content, more than average (0,2167%). The study should be followed with other studies to prove that the cause is only by air SOx and to calculate number of trees required for absorbing SOx produced by PT Inco.
