Abstract

Jalan tol merupakan salah satu infrastruktur penting yang bertujuan untuk memenuhi kebutuhan akan akses yang cepat dan nyaman. Jalan Tol Probolinggo Banyuwangi dibangun untuk meningkatkan konektivitas dan mobilitas masyarakat dan logistik sehingga mempercepat pembangunan ekonomi di wilayah Jawa Timur. Pada proyek Jalan Tol Probolinggo Banyuwangi STA 45+300 hingga STA 46+000 direncanakan menggunakan timbunan tanah dengan tinggi timbunan 5 meter yang terletak di atas tanah lunak dengan N-SPT kurang dari 10 hingga kedalaman 8 meter. Tanah lunak ini memiliki daya dukung rendah dan berpotensi mengalami settlement besar, serta laju pemampatan berpotensi tidak memenuhi persyaratan Ditjen Bina Marga. Tugas akhir ini bertujuan membandingkan material dan metode timbunan. Pada tugas akhir ini direncanakan timbunan dengan kombinasi ketebalan material tanah timbunan dan mortar busa 100% tanah, 25% mortar busa 75% tanah, 50% mortar busa 50% tanah, 75% mortar busa 25% tanah, dan 100% mortar busa, dengan Prefabricated Vertical Drain (PVD) atau Replacement serta direncanakan perkuatan geotextile atau cerucuk bila diperlukan. Hasil yang diketahui adalah semakin tebal tanah memampat, semakin besar pemampatannya, semakin tebal mortar busa semakin kecil pemampatannya, dan semakin tebal replacement semakin kecil pemampatannya. Diketahui juga timbunan mortar busa lebih stabil lerengnya, serta timbunan mortar busa lebih mahal daripada timbunan tanah. Biaya timbunan yang dipilih paling mahal sebesar Rp48,623,807,754.05.

The toll road is one of the essential infrastructures aimed at meeting the need for fast and convenient access. The Probolinggo–Banyuwangi Toll Road is being constructed to improve connectivity and mobility for both the public and logistics, thereby accelerating economic development in the East Java region. In the Probolinggo–Banyuwangi Toll Road project from STA 45+300 to STA 46+000, an embankment with a height of 5 meters is planned, located on soft soil with an N-SPT value of less than 10 to a depth of 8 meters. This soft soil has low bearing capacity and the potential for significant settlement, with the compression rate potentially failing to meet the requirements of the Directorate General of Highways. This thesis aims to compare embankment materials and methods. The embankment is planned using a combination of soil and foam mortar layers: 100% soil, 25% foam mortar and 75% soil, 50% foam mortar and 50% soil, 75% foam mortar and 25% soil, and 100% foam mortar, with the addition of Prefabricated Vertical Drains (PVD) or Replacement, and geotextile or pile reinforcement if necessary. The results show that the thicker the compressible soil, the greater the settlement; the thicker the foam mortar, the smaller the settlement; and the thicker the replacement, the smaller the settlement. It is also found that foam mortar embankments have more stable slopes and are more expensive than soil embankments. The most expensive embankment option selected costs Rp48,623,807,754.05.
