Abstract
Mortar Geopolimer tersusun dari material geopolimer yang berfungsi untuk menggantikan pasta semen. Bahan dasar utama geopolimer adalah material yang mengandung silika (SiO2) dan alumina (Al2O3) seperti fly ash, GGBFS (ground granulated blast furnace slag). Namun, rata-rata material tersebut tidak memiliki kemampuan untuk adsorpsi methylene blue, maka dari itu penambahan Metakaolin diperlukan untuk membantu kemampuan mortar untuk adsorpsi methylene blue. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan Metakaolin terhadap kuat tekan dan kemampuan adsorpsi methylene blue mortar geopolimer berbasis fly ash dan GGBFS. Dengan rasio fly ash, GGBFS, metakaolin dan larutan alkali yang tepat sesuai dengan mix design diharapkan dapat meningkatkan kuat tekan dan kemampuan adsorpsi limbah methylene blue pada mortar geopolimer1. Pengujian karakterisasi yang dilakukan pada penelitian ini diantaranya uji XRF, FTIR, XRD, SEM�EDX, dan BET. Kemudian, mortar yang dihasilkan dilakukan pengujian densitas mortar, water absorption, kuat tekan, adsorpsi methylene blue, dan UV-Vis. Dari hasil penelitian, diperoleh nilai densitas mortar berdasarkan ASTM C905 mengalami penurunan seiring dengan meningkatnya persentase penambahan metakaolin dan menurunnya persentase penambahan GGBFS, dengan nilai maksimum didapatkan pada variasi F70G25M5 sebesar 2,41834 g/cm3. Nilai penyerapan air mortar berdasarkan ASTM C1403 memiliki nilai maksimum pada variasi F70G5M25 sebesar 20.8-34.8 g/100 cm2. Kuat tekan mortar berbanding lurus dengan nilai densitas, dengan nilai maksimum didapatkan pada variasi F70G25M5 sebesar 50,37 MPa. Persentase pertambahan massa setelah dilakukan adsorpsi limbah methylene blue memiliki nilai yang berbanding terbalik dengan nilai kuat tekan dan densitas, dengan nilai removal efficiency maksimum didapatkan pada variasi F70G5M25 sebesar 73,80095 %

Geopolymer mortar is composed of geopolymer material that functions to replace cement paste. The main raw material of geopolymer is material containing silica (SiO2) and alumina (Al2O3) such as fly ash, GGBFS (ground granulated blast furnace slag). However, on average these materials do not have the ability to adsorb methylene blue, therefore the addition of Metakaolin is needed to help the mortar's ability to adsorb methylene blue. This study aims to analyze the effect of adding Metakaolin on the compressive strength and adsorption capacity of methylene blue geopolymer mortar based on fly ash and GGBFS. With the right ratio of fly ash, GGBFS, metakaolin and alkali solution according to the mix design, it is expected to increase the compressive strength and adsorption capacity of methylene blue waste in geopolymer mortar1. Characterization tests carried out in this study include XRF, FTIR, XRD, SEM�EDX, and BET tests. Then, the resulting mortar was tested for mortar density, water absorption, compressive strength, methylene blue adsorption, and UV-Vis. From the research results, the mortar density value based on ASTM C905 decreased along with the increasing percentage of metakaolin addition and decreasing percentage of GGBFS addition, with the maximum value obtained in the F70G25M5 variation of 2.41834 g/cm3. The water absorption value of mortar based on ASTM C1403 has a maximum value in the F70G5M25 variation of 20.8-34.8 g/100 cm2. The compressive strength of mortar is directly proportional to the density value, with the maximum value obtained in the F70G25M5 variation of 50.37 MPa. The percentage of mass increase after adsorption of methylene blue waste has a value that is inversely proportional to the compressive strength and density values, with the maximum removal efficiency value obtained in the F70G5M25 variation of 73.80095%.
