Abstract: School  bench  is  one  of  the  facilities  that  identified  could  cause  musculoskeletal  pain  in  school-age  children. During  class,  students  often  sit  with  poor  posture,  back  and  neck  bent  in  a  long  time  so  that  musculoskeletal  pain  often occur in a classroom. Based on research conducted by Ira Idawati, school bench design needs to be different for each level of  class  because  children  have  different  anthropometric  at  each  grade  level  elementary  school-age.  This  can  be  done  by designing  school  bench  with  fixed  or  adjustable  size.  If  school  decides  to  use  fixed  size  bench,  it  is  recommended  to  use several size of bench based on the level of the class. But if school used with adjustable size, the school could only buy one type and size of bench with a certain level of ergonomics. This study analyzed the used of the fixed and adjustable school bench  design  in  elementary  school  based  on  economically  and  ergonomics.  The  result  from  this  study  shown  that elementary  student  who  sit  on  fixed  size  bench  had  a  larger  risk  to  the  body  than  adjustable  bench  size  from  REBA  and RULA scores. This suggests that adjustable bench was recommended for teaching and learning process facilities for health and  to  prevent  injury  on  child.  From  economic  terms,  the  value  of  the  Net  Present  Value  for  fixed  size  bench  is  more economical than the adjustable one. From this two aspect, the elementary school had references to make school bench type decision.
