Abstract— Jabor landfill commonly known as Kuantan landfill receives more than 500 tons per day waste with a composition of 60% of domestic waste and 40% of industrial waste. Landfill system always produce leachate. This waste contains many types of bacteria which potential to degrade the waste compound. Samples were taken from different places, landfill soil and leachate. Bacteria found in landfill soil were 19 different species of bacteria which are three Gram positive and 16 Gram negative bacteria. Bacteria were found in leachate tank were found to be 18 different species of bacteria. Those are five Gram positive and 13 Gram negative bacteria. Almost all of the bacteria in the soil and landfill leachate are able to produce amylase and protease enzymes, but only a few bacteria produce the lipase enzyme. The best bacteria are Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus subtilis, Bacillus ruris and Kocuria varians.

Index Terms— Landfill, leachate, Bacillus, Gram negative and Gram positive bacteria.
