Abstract
Penggunaan semen dalam pembangunan industri tanpadisadari merupakan 8% penyumbang emisi karbon terbesar di dunia. Pembuatan semen adalah proses yang menghasilkan Karbon Dioksida (CO2) dalam proses nya. Olehk karna itu pembuatan Mortar berbasis GGBFS serta penambahan variasi Fly ash dan Karbon Aktif ditujukan untuk pembangunan kedepan yang lebih ramah lingkungan. Pada penelitian ini Fly ash dan juga GGBFS digunakan sebagai bahan substitusi semen dengan memanfaatkan kandungan CaO dan juga SiO2 ¬yang tinggi. Di sisi lain pemanfaatan Karbon Aktif digunakan sebagai adsorben CO2 yang ada dilingkungan dengan memanfaatkan pori pori yang dimiliki oleh Karbon Aktif. Penelitian ini bertujuan untuk menganalaisis pengaruh variasi Karbon Aktif dan fly ash terhadap kemampuan kuat tekan dan pengangkapan gas CO2 yang dimiliki mortar GGBFS yang dibuat dengan komposisi 0%,5%,10%,15%, dan 20% secara bergantian sehingga bisa disebut sebagi komposit FA/GGBFS/Semen/Karbon Aktif/Semen dengan curing time selama 7, 14 ,dan 28 hari pada wadah berisi air untuk memicu reaksi hidrasi pada mortar. Material yang digunakan pada penelitian ini dilakukan pengujian karakterisasi dengan fourier-transform infrared spectroscopy (FTIR), Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX), dan X-ray diffraction (XRD) serta pengujian Brunauer-Emmet-Teller (BET) untuk Karbon Aktif. Juga dilakukan uji SEM-EDX, XRD, FTIR, densitas, penyerapan air, kekuatan tekan dan pengujian CO₂ adsorpsi pada benda uji mortar GGBFS. Dari hasil penelitian yang dilakukan didapatkan bahwa seiring dengan pertambahan material Karbon Aktif mortar semakin berpori dan mempunyai kemampuan adsorpsi yang semakin baik, namun hal ini disisi lain mengunrangi densitas dari mortar dan sehingga mortar juga mempunyai kuat tekan yang menurun dengan penambahan Karbon Aktif dilain sisi penggunaan Fly ash dengan kandungan SiO2 yang cukup tinggi dapat membuat mortar mempunyai kuat tekan yang lebih tinggi hal ini karna ada nya reaksi pozzolan yang terjadi. Oleh karna itu dapat ditentukan variasi dengan kuat tekan maksimum yaitu pada komposisi FA15%KA5% yang mempunyai kuat tekan 29,48 Mpa dan mortar dengan kemampuan adsorpsi maksimum yaitu pada komposisi FA5%KA15% pada kemampuan adsopsi CO2 sebesar 1,0507%.

The use of cement in industrial development is unwittingly 8% of the largest contributor to carbon emissions in the world. Cement-making is a process that produces Carbon Dioxide (CO2) in the process. Therefore, the manufacture of GGBFS-based mortar and the addition of variations of Fly ash and Activated carbon is aimed at future development that is more environmentally friendly. In this research, fly ash and GGBFS were used as cement substitution materials by utilizing the high CaO and SiO2 content. On the other hand, the use of activated carbon is used as an adsorbent for CO2 in the environment by utilizing the pores of activated carbon. This research aims to analyze the effect of variations in activated carbon and fly ash on the compressive strength and CO2 gas trapping capabilities of GGBFS mortar which is made with compositions of 0%, 5%, 10%, 15%, and 20% alternately so that it can be called a composite. FA/GGBFS/Cement/Activated carbon/Cement with a curing time of 7, 14, and 28 days in a container filled with water to trigger a hydration reaction in the mortar. The materials used in this research were tested for characterization using Fourier-transform infrared spectroscopy (FTIR), Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX), and X-ray diffraction (XRD) as well as the Brunauer-Emmet-Teller test ( BET) for Activated carbon. SEM-EDX, XRD, FTIR, density, water absorption, compressive strength, and CO₂ adsorption tests were also carried out on GGBFS mortar test specimens. From the results of the research carried out, it was found that as the activated carbon material was added, the mortar became more porous and had better adsorption capabilities, however, this on the other hand reduced the density of the mortar and so the mortar also had a reduced compressive strength with the addition of activated carbon, on the other hand, the use of fly. Ash with a high enough SiO2 content can make the mortar have a higher compressive strength, this is because there is a pozzolan reaction that occurs. Therefore, variations with the maximum compressive strength can be determined, namely the composition FA15%KA5% which has a compressive strength of 29.48 Mpa, and the mortar with maximum adsorption capacity, namely the composition FA5%KA15% with a CO2 adsorption capacity of 1.0507%.
