  <abstract>Population growth with  increasing  consumption  levels  leads  to abundant waste in  Kuantan.  Jabor  landfill,  commonly  known  as  Kuantan  landfill,  receives  more  than 500 tons  of  waste  per  day  with  a  composition  of  60% of  domestic  waste  and  40% of commercial waste. The composition of domestic waste were organic waste, green waste, mixed paper, plastic, textile, ferrous, glass, rubber and leather, and others. Meanwhile, the compositions of  commercial  waste are  food, plastic,  yard  waste, paper, cardboard, textile,  glass,  non-ferrous,  rubber,  wood,  ferrous  metals.  Landfill  system  always produces  leachate.  This  waste  contains  many  types  of  bacteria  with  the  potential  to degrade  the  waste  compound.  Screening  tests  with  selective  media  demonstrated  the ability  of  bacteria  to  produce  amylase,  lipase,  protease  and  cellulase  enzymes.  These enzymes are needed to accelerate the molecules breakdown of municipal solid waste in the biodegradation process. Samples  for isolation of bacteria  were taken from different places, namely landfill soil and leachate. Identification of bacteria was conducted using Gen  III  microplate  BIOLOG  microbial  identification  system.  They  were  Bacillus amyloliquefaciens, Bacillus ruris, Bacillus licheniformis, Bacillus subtilis  and  Kocuria varians.  There  were  4  different  treatments:  composting  pile  wit hout  bacteria  (T0), composting  pile  with  inoculation  of  amylase  and  protease  producing  bacteria  (T1),composting  with  inoculation  of  lipase  and  cellulase  producing  bacteria  (T2),  and composting  with  inoculation  all  enzyme-producing  bacteria  (T3).  The  result  of biodegradation process of T3 treatment reached the highest temperature (53° C) with the longest thermophilic phase compared to other treatments. The  lower  value of C/N ratio, the more stable the level of maturity of compost. The  lowest of C/N ratio value was T3 (10%).  T3  treatment  compared  with  other  treatments  can  increase  as  much  as  27% content of nitrogen, 67% of phosphorus and 33% of potassium. All the treatments with bacterial inoculation (T1, T2, and T3) are able to reduce the content of heavy metals (Fe, Zn,  Cu)  on  municipal  solid  waste  biodegradation.  It  can  be  concluded  that  the inoculation  of  potential  enzyme-producing  of  bacteria  on  municipal  solid  waste biodegradation  is  effective  to  increase  the  nutrient  content  and  decrease  the  heavy metals.</abstract>
