Pengolahan POFA (Palm Oil Fuel Ash) dan Semen Sebagai Material Alternatif Timbunan Pilihan Jalan Untuk Perbaikan Infrastruktur Jalan

peningkatan seiring semen disetiap variasi. Nilai CBR dan UCS mengalami kenaikkan mencapai nilai maksimum penambahan kadar 12 yaitu sebesar 28,01% untuk CBR 4,903 kg/cm untuk UCS. Nilai diperoleh . ABSTRACT The development of the palm oil industry which continues to increase has an impact on palm oil waste in the form of ash from burning palm shells, known as POFA (Palm Oil Fuel Ash). One way to reduce the number of POFA is to use it in the field of Civil Engineering. In this study, Palm Oil Fuel Ash (POFA) was used as a material for the embankment in road pavement construction. In addition to using POFA, this study also used additional materials in the form of cement with the percentage addition of 2%, 4%, 6% and 12%. The results of the soaked CBR and UCS tests in the laboratory showed that the CBR and UCS values increased with increasing cement content in each variation. The value of CBR and UCS increased and reached the maximum value at the addition of 12% concentration, which was 28.01% for CBR and 4.903 kg/cm2 for UCS. The value obtained has reach the standard and can be used as a choice of embankment material.
