This research methodology uses experimental approach in laboratory by making cylinder paste test object with dimension diameter of 2.5 cm x height 5 cm with some combination of fly ash and bottom ash mix with time setting test (ASTM C 191-04a) and compressive strength (ASTM C 39-04a). The research concludes that the effect of bottom ash on fly ash-based geopolymer paste shows good results in setting time and compressive strength. © Published under licence by IOP Publishing Ltd. publisher: Institute of Physics Publishing date: 2017 type: Conference or Workshop Item type: PeerReviewed identifier: Affandhie, B.A. and Kurniasari, P.T. and Darmawan, M.S. and Subekti, S. and Wibowo, B. and Husin, N.A. and Bayuaji, R. and Irawan, S.
