Abstract

Dalam pelaksanaan membangun suatu jalan sering dijumpai tanah dalam keadaan yang kurang baik dengan sifat kembang susut tinggi yaitu mengembang pada kondisi basah dan menyusut pada waktu kering sehingga menyebabkan kerusakan pada struktur jalan yang menjadikan jalan bergelombang atau retak – retak untuk alasan inilah peneliti ingin mengetahui jenis tanah di jalan Desa Cibeulah, Pandeglang dan distabilisasikan dengan bahan campuran tambahan yaitu abu sawit. Pada penelitian ini dilakukan beberapa pengujian yaitu pengujian fisik tanah dan pengujian UCT. Pengujian fisik tanah diantaranya analisa besar butir, berat jenis butir, kadar air, batas plastis, batas cair, dan pemadatan. Sedangkan pada pengujian UCT dilakukan dengan cara stabilisasi tanah menggunakan bahan aditif berupa abu sawit dengan nilai kuat tekan bebas. Hasil pengujian fisik tanah menunjukkan bahwa tanah tersebut masuk pada golongan tanah lempung tak organik dengan plastisitas rendah dengan presentasi lolos saringan no. 200 sebesar 55%, berat jenis = 2.68, kadar air mula�mula = 25,03%, Batas Cair (LL) = 29,4%, Batas Plastis (PL) =17,663%, indeks plastis (PI) = 11.737%, kadar air optimum = 29%, dan  d maksimum = 1.380 gr/cm3 . Hasil pengujian UCT terlihat bahwa baik waktu pemeraman maupun presentasi abu sawit yang diberikan pada material pengujian akan mempengaruhi nilai kuat tekan bebas. Dengan lama pemeraman 28 hari dan bahan campuran sebesar 15% menghasilkan nilai kuat tekan bebas 2.575 kg/cm2 , peningkatannya hingga 329.16 % dari nilai qu pada presentase abu sawit 0% dengan lama pemeraman 0 hari

Additional Information:	In the construction of street we often find adverse land contour with high shrinkage swelling which expands on the conditions of wet and shrink when dry, that caused structure damage and becomes bumpy or cracked, for this reason the researcher wants to studying the type of soil in Village Cibeulah, Pandeglang and stabilized it with additive material that is palm ash. The study conducted a few tests that physical testing ground and testing UCT (Unconfined Compression Test). Physical testing including analysis of grain size, grain density, moisture content, plastic limit, liquid limit, and compaction. While proceed UCT testing through by soil stabilization using the additive in the form of palm ash with value compressive strength. Soil physical test results show that the land was classified in the class of inorganic clay with low plasticity percentage through sieve no. 200 by 55%, density = 2.68, water content initially = 25.03%, Liquid Limit (LL) = 29.4%, Plastis Limit (PL) = 17.663%, Plasticity Index (PI) = 11 737% The optimum water content = 29%, and a  d (dry density) maximum = 1.380 g / cm3 . UCT results shown that both the curing time and the presentation of palm ashes given to the test material will affect the unconfined compression strength. With a curing time of 28 days and a mixture of 15% produces unconfined compression strength 2,575 kg / cm2 which increases the unconfined compression strength up 329.16 % of the value of the percentage of palm ash 0% at 0 days curing time.
