Abstract

Stabilisasi merupakan usaha dalam memperbaiki sifat fisik tanah dan mekanika tanah sehingga memenuhi persyaratan teknis tertentu. Salah satu cara dilakukan untuk stabilisasi adalah denga nadanya penambahan zat adiktif berupa abu terbang (Fly Ash). Penelitian ini bertujuan mengetahui nilai CBR maksimum Pada tanah rawa pasang surut yanag ada di Kecamatan Alalak Kabupaten barito kuala. setelah dilakukannya stabilisasi menggunakan zat adiktif menggunakan abu terbang (FlyAsh), Serta mengetahui variasi proporsi campuran kadar Fly Ash terhadap tanah rawa pasang surut yang ada di Kecamatan Alalak Kabupaten barito Kuala. Variasi penambahan kadar Fly Ash yang digunakan 10%, 20%, 30%, sedangkan variasi waktu dalam Perendaman sesuai SNI 1744 : 2012 selama 4 hari. Pada hasil pengujian pemadatan modified proctor, penambahan kadar Fly Ash paada tanah rawa Pasang surut terbukti meningkatkan berat volume kering maksimum (γd) secara berlanjut. Sedangkan nilai kadar air optimum (ωopt) mengalami peneurunan yang tidak terlalu signifikan pada setiap penambahan kadar Fly Ash.. Pada pengujian CBR Laboratorium dengan menggunakan pemadatan modified proctor pada penambahan kadar Fly Ash 10% dan waktu perendaman selama 4 hari didapat nilai CBR Laboratorium maksimum sebesar 10,3%. Penambahan Fly Ash terbukti dapat meningkatkan CBR dan nilai daya dukung tanah. Stabilization is an effort to improve the physical properties of the soil and soil mechanics so that it meets certain technical requirements. One way to do it for stabilization is by adding an addictive substance in the form of fly ash (Fly Ash). This study aims to determine the maximum CBR value in tidal swamp land in Alalak District, Barito Kuala Regency. after stabilization using an addictive substance using fly ash (FlyAsh), and knowing the variation in the proportion of the mixture of Fly Ash levels to tidal swamp soil in Alalak District, Barito Kuala Reg ency. Variations in the addition of Fly Ash content used were 10%, 20%, 30%, while the time variation in soaking was according to SNI 1744 2012 for 4 days. In the modified proctor compaction test results, the addition of Fly Ash content in tidal swamp soil was proven to increase the maximum dry volume weight (γd) continuously. While the value of the optimum water content (ωopt) decreased which was not too significant at each addition of Fly Ash levels. In Laboratory CBR testing using modified proctor compaction at the addition of 10% Fly Ash content and immersion time for 4 days obtained the maximum Laboratory CBR value of 10.3%. The addition of Fly Ash is proven to increase the CBR and the bearing capacity of the soil.
