description: Geopolimer merupakan material anorganik yang tersusun dari Si dan Al sehingga  dapat digunakan sebagai alternatif pengganti semen melalui reaksi polimerisasi.  Beberapa penelitian telah menunjukkan bahwa suhu dan waktu pemanasan dapat  berpengaruh terhadap sifat mekanis, sifat fisis dan karakteristik geopolimer. Pada  penelitian ini digunakan variasi suhu yaitu 40 ̊C, 60 ̊C, 80 ̊C dan 100 ̊C dengan  waktu pemanasan 6, 10 dan 14 jam. Geopolimer yang digunakan yaitu mortar  geopolimer berukuran 5×5×5 cm3    , berbahan fly ash, slag boiler, NaOH molaritas  10M, Na2SiO3 dan air. Pengujian sampel terdiri dari uji kuat tekan, uji absorpsi, uji  porositas dan uji densitas. Sampel dikarakterisasi menggunakan alat XRF dan  SEM-EDS. Sampel terbaik diperoleh pada suhu 80 ̊C selama 14 jam dengan nilai  kuat tekan 22,80 MPa, absorpsi sebesar 5,80%, porositas sebesar 19,73% dan  densitas 3,40 g/cm3    . Hasil karakterisasi sampel menggunakan XRF yaitu senyawa  SiO2 sebesar 52,129%, CaO sebesar 12,936%, Al2O3 sebesar 12,234% dan  Fe2O3sebesar 10,516%. Hasil karakterisasi sampel menggunakan SEM-EDS  didominasi unsur O sebesar 47,98%, C sebesar 37,47%, Si sebesar 6,90% dan Al  sebesar 3,63%. Berdasarkan hasil penelitian, dapat disimpulkan bahwa variasi suhu  dan waktu pemanasan berpengaruh terhadap sifat mekanis, fisis dan karakteristik  geopolimer berbahan fly ash dan slag boiler.    Kata Kunci: geopolimer, pemanasan, fly ash, slag boiler, karakterisasi  Geopolymers are inorganic materials composed of Si and Al that can be used as an  alternative to cement through polymerization reactions. Some researchers have  shown that heating temperature and time can affect the mechanical properties,  physical properties and characteristics of geopolymers. In this study, temperature  variations of 40 ̊C, 60 ̊C, 80 ̊C and 100 ̊C with heating times of 6, 10 and 14 hours  were used. The geopolymer used is a 5×5×5 cm3geopolymer mortar made from fly  ash, boiler slag, NaOH molarity 10M, and water. Sample testing consisted of  compressive strength test, absorption test, porosity test and density test. The  samples were characterized using XRF and SEM-EDS. The best sample was  obtained at 80 ̊C for 14 hours with a compressive strength of 22.80 MPa,  absorption of 5.80%, porosity of 19.73% and density of 3.40 g/cm3    .. The results  of sample characterization using XRF are compounds SiO2 of 52.129%, CaO of  12.936%, Al2O3 of 12.234% and Fe2O3 of 10.516%. The results of sample  characterization using SEM-EDS are dominated by the element O by 47.98%, C by  37.47%, Si by 6.90% and Al by 3.63%. Based on the results research, it can be  concluded that variations in heating temperature and time affect the mechanical  properties, physical properties and characteristics of geopolymers made from fly  ash and boiler slag.
