Amorphous silica is the demand raw material nowadays by  the chemical  industry  as  it  is  widely  used  in  the  production  of  resin,  optical  beads, glass,  porcelain  and  in  the  semiconductor  circuit.  Most  of  the  amorphous  silica previously were produce from rice husk ash due to its low cost and is environmentally friendly. This research was conducted to find an alternative way and optimum condition to produce amorphous silica from sugar cane leaves ash by chemical extraction method. This is due to its low cost and can be one of the effective ways to dispose agricultural waste. The scope of this research are to study the effect of extraction temperature used during extraction process, the effect of extraction time and the effect of different solvent used to the  yield of amorphous silica produced.  This research was conducted by using pretreatment  method  of the  sugar  cane  leaves  ash  followed  by  soxhlet  extraction method.  Based  on  the results  obtained  and  analysis,  it  was  confirmed  that  sugar  cane leaves is one of the sources to produce amorphous silica and the optimum condition to produce  amorphous  silica is  at  high  temperature  of  extraction  which  is  at  80°C,  and  8 hours  time  of  extraction  and  by  using  methanol  as  the  extraction  solvent.  The  silica obtained  from  the  extraction  process  was  characterized  by  using  Fourier  Transform Infrared  Spectroscopy (FTIR).  As  a  conclusion,  it  was  confirm  that  sugar  cane  leaves contain SiO2 compound based on the wavelength analysis obtained from FT-IR. 0aExtraction (Chemistry) 0aSilica  00104071a10000b10000d2019-09-04l0oTP156.E8 N39 2012 rs Bc.p0000067963r2019-09-04 00:00:00t1w2019-09-04yPSM  00104071a10000b10000d2019-09-04l0oCD 6319 | TP156.E8 N39 2012 rs Bc.p0000067964r2019-09-04 00:00:00t1w2019-09-04yPSM  aVIRTUA40c3652d3658  aVTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5020*5040*5200*6500*6501*9992
