“…Tanah dasar yang berupa lempung yang memiliki daya dukung rendah yang nantinya bisa berdampak pada konstruksi yang ada diatasnya [1]. Untuk dapat memikul beban yang ada diatasnya tanah tersebut harus memiliki sifat dan daya dukung yang baik [2], Pembangunan konstruksi jalan sangat penting diperhatikan terutama subgrade jalan yang harus memiliki daya dukung yang bagus sehingga nantinya dapat mendukung beban diatasnya. Tanah lempung merupakan salah satu jenis tanah yang ada di Indonesia [3].…”

Daya dukung dan kuat geser tanah merupakan sifat-sifat yang ada pada tanah yang sangat perlu diperhatikan. Untuk tanah lempung parameter tersebut perlu diperhatikan sehingga nantinya dapat memikul beban konstruksi yang ada diatasnya. Konstruksi jalan merupakan salah satu contoh bangunan sipil yang dibangun diatas tanah. Subgrade jalan sangat perlu diperhatikan untuk pembangunan konstruksi jalan, dimana harus memiliki daya dukung yang baik. Perbaikan tanah yang bisa dilakukan untuk meningkatkan daya dukung dan memperbaiki sifat tanah lempung yang mudah mampat yaitu dengan stabilisasi. Stabilisasi tanah dengan pencampuran abu tandan sawit dan semen pada tanah lempung akan meningkatkan nilai kuat gesernya. Tujuan penelitian ini adalah untuk meningkatkan nilai kuat geser tanah lempung dengan campuran 7,5% abu tandan sawit dan 5%, 7.5%, dan 10% semen. Metode yang digunakan adalah SNI 3420:2016 untuk pengujian kuat geser. Hasilnya dari pengujian kuat geser di laboratorium nilai kohesi ( c ) dan sudut geser (φ ) tertinggi pada 7,5% abu tandan sawit dan 10% semen dengan nila kohesi 0,480 dan nilai sudut geser 41,54°. Kesimpulannya penambahan abu tandan sawit dan semen dapat meningkatkan nilai kohesi dan sudut geser tanah lempung.

Roads with subgrades that have soft soil (clay) characteristics are a problem that often occurs in these soil conditions because they have a very low bearing capacity. This condition is if the road construction that is built on it will cause damage. As a result, soil subsidence is not uniform in soil conditions that have a low bearing capacity. The type of soil used in this study is clay soil taken from the Garuda Sakti km.13 Kampar district, Riau. The purpose of this study was to increase the bearing strength of the soil by stabilizing the clay soil with a mixture of 5%, 10%, 15%, 20%, of oil palm bunch ash mixture, and 10% cement to increase the value of the California Bearing Ratio (CBR). The method used is laboratory testing to get the CBR value which refers to the California Bearing Ratio (CBR) test using SNI 03-1744-2008. From the results of atterberg tests carried out, the higher the variation of oil palm bunch ash and cement on clay soil, the atterberg value tends to decrease. The liquid limit value (PL) is 57.93% -43.16% -24.94% and the plastic limit (LL) is 27.35% -24.94%, causing the plastic index value to decrease by 16.73%. The higher the percentage of oil palm bunch ash and cement mixed with clay soil, the better the mixed soil is due to the reduced plasticity in the original soil. Testing the maximum CBR value in the laboratory with a variation of 15% oil palm bunch ash and 10% cement by 70.5%, the CBR value obtained meets the General Specifications of Bina Marga CBR 6%. The addition of Palm Oil Bunch Ash and cement can increase the CBR value in clay soils. The more variations in the levels of Ash and cement, the CBR value of the clay soil will increase. In conclusion, the variation of 15% oil palm bunch ash and 10% cement resulted in a maximum CBR value of 70.5%.

“…This clay when it has a moderate water content will be plastic and will be hard when in dry conditions [6]. High plasticity clay has a fine grain size so it has a low bearing capacity [7]. Clay soil contains water which is large in wet conditions, so that in In this condition, clay soil has very low ability in support the load on it [8].…”

Soil is a very important element in the success of a development project and is part of the foundation used. Therefore, stable soil is needed to obtain the required soil bearing capacity. Such as clay has the characteristics of low bearing capacity and large shrinkage. This study aims to determine the increase in the value of the shear strength of clay with the stabilization of PET plastic waste. The purpose of this study is to see the value of the shear strength of clay with variations in the amount of plastic waste 0%, 3.5%, 4%, and 4.5%. Method used is SNI 3420:2016 for the shear strength test. As a result, the addition of shredded plastic waste can increase the value of the shear strength of the soil.The value of shear strength increased at the percentage of plastic addition of 3.5% of 0.5663 kg/cm2 in the original soil test, the value of shear strength was 0.5271 kg/cm2, an increase of 7.43%. The conclusion is that there is an increase in the value of the shear strength of the soil stabilized by plastic waste at a variation of 3.5% of plastic waste, an increase of 7.43%.
