BNPB (2016) menyatakan lebih dari 10 kali tanggul penahan lumpur Sidoarjo mengalami keruntuhan. PPLS (2018) telah melakukan penelitian pemanfaatan LuSi untuk tanggul uji. Berdasarkan pengamatan tahun 2019 terdapat retakan pada tanggul ditengarai akibat perubahan karakteristik tanah saat terjadi perubahan musim. Penelitian ini bersifat pemodelan menggunakan data sekunder penelitian terdahulu. Tujuan penelitian untuk mengetahui faktor keamanan konfigurasi geometri tanggul pada variasi muka air tanah dan endapan lumpur dengan pengaruh nilai suction pada SWCC dari data penelitian terdahulu. Hasil pemodelan pada muka air tanah (M.A.T) 0 m rentang angka keamanan 1,7-3,4 dan muka air tanah (M.A.T) -30 m rentang antara 2,4 - 4,6. Pemodelan pengaruh endapan lumpur yaitu saat endapan lumpur rendah (1 m) rentang angka keamanan yaitu 1,8-3,5, untuk endapan lumpur tinggi (3 m) rentang 2,5-7,0. Besar pemampatan segera (Immediate Settlement) semakin tinggi timbunan rentang pemampatan 0,08876 m -0,10107 m dan semakin besar kemiringan tanggul rentang 0,08876 m - 0,02166 m.

Kota Surabaya merupakan salah satu kota besar di Indonesia yang selalu bermasalah dalam bidang transportasi terutama kemacetan. Adanya pembangunan fly over yang melintasi jalur trek ganda kereta api Stasiun Benowo – Stasiun Kandangan KM 219+958 yang terletak di Desa Kandangan ini termasuk salah satu solusi untuk mengatasi kemacetan di Surabaya barat khususnya di daerah Kandangan dan sebagai jalur alternatif menuju Gresik. Pada penulisan studi ini penulis memodifikasi desain awal fly over Kandangan yang awalnya dengan konstruksi pilar disetiap bentangnya, dirubah menjadi timbunan tanah dengan alasan biaya timbunan lebih ekonomis daripada konstruksi pilar jembatan. Direncanakan alternatif bentuk timbunan` oprit serta perkuatan tanah timbunan dan perbaikan tanah dasarnya. Dua alternatif bentuk timbunan yang dibandingkan yaitu timbunan bersisi tegak dan bersisi miring. Dalam perencanaan perkuatan oprit bersisi tegak akan dibandingkan dua alternatif perkuatan antara lain: geotextile wall reinforcement kombinasi dengan flat sheet-pile concrete, dan geogrid wall reinforcement kombinasi dengan keystone wall. Sedangkan untuk perencanaan perkuatan oprit bersisi miring akan dibandingkan dua alternatif perkuatan antara lain: geotextile slope reinforcement dan cerucuk berupa micropile beton. Abutment direncanakan dengan kestabilan konstruksi harus ditinjau terhadap pengaruh gaya-gaya eksternal maupun terhadap gaya-gaya internal yang dapat menyebabkan pecahnya konstruksi. Apabila abutment tidak memenuhi maka daya dukungnya harus direncanakan pondasi dalam berupa tiang pancang. Hasil dari perhitungan total biaya konstruksi pada perencanaan oprit didapatkan diantaranya untuk oprit bersisi tegak dengan alternatif perkuatan geotextile kombinasi sheet-pile adalah Rp. 86.280.857.674,34 dan untuk alternatif perkuatan geogrids kombinasi keystone-wall adalah Rp. 73.797.613.851,84. Sedangkan untuk oprit bersisi miring dengan alternatif perkuatan geotextile adalah Rp. 103.183.365.174,93 dan untuk alternatif perkuatan micropile adalah Rp. 134.243.009.394,93. Maka dipilih alternatif timbunan dan perkuatan yang paling efektif dari segi biaya, pelaksanaan, dan hemat ruang sehingga oprit bersisi tegak dengan perkuatan geogrids kombinasi keystone-wall adalah yang paling sesuai. Sedangkan untuk abutment direncanakan dengan lebar melintang 32,725 m dan tinggi total 12,530 m. Dimensi pilecap 32,725 m x 6,5 m. Pondasi dalam dipakai tiang pancang PC Spun Pile diameter 60 cm berjumlah 84 buah dengan dipancang kedalaman 42 m dari OGL.

Slope stability analysis is very important in slope design so it can manage and maintain the infrastructure assets. If the slope is unstable, it can damage the infrastructure around the slope. The method commonly used in slope stability analysis is 2D modeling which assumes the length of the landslide area is not limited or continuous. In fact, landslides that occur in the field are limited and not continuous, so 3D modeling is more suitable than 2D modeling. 3D slope stability analysis has been developed by various researchers. Most of the results of previous studies stated that the 3D and 2D factor of safety ratio was more than one for cohesive soils and less than one for non-cohesive soils. This safety factor affects the amount of reinforcement needed. Differences in 2D and 3D safety factors will cause differences in the amount of reinforcement needed. Therefore, this study was conducted to determine the differences in the 2D and 3D slope stability analysis result. Slope stability analysis was carried out using LEM, where the 2D slope stability used the Fellenius method while the 3D slope stability used the Hovland method. Calculate the required reinforcement amount using geotextiles with Tult = 250 kN/m. The results obtained from this study are the 2D safety factor is smaller than the 3D safety factor. The 3D and 2D safety factor ratios range from 1.09 – 1.397. While the amount of reinforcement required in the 3D analysis is less than in the 2D analysis with the ratio of 3D and 2D reinforcement requirements ranging from 0.5 to 0.955 depending on the width and height of the embankment.

The infrastructure is important for the great life of a region and most of the country. Therefore, infrastructure must be always in proper condition in its functionality. Furthermore, it must follow the main principle which is infrastructure asset management. In this case, geotechnical mapping is also related to the principles of Infrastructure Asset Management in planning, designing, and feasibility studies of an infrastructure project in Badung Regency, hence the infrastructure projects are better prepared. The research methods include collecting soil investigation data, processing soil investigation data, describing the results of soil investigation data with mapping tools, and geotechnical zoning with statistical analysis. The results obtain geotechnical map of Badung Regency in 2 and 3-dimensional form. The 2D results in the form of a hard soil depth map can be concluded that South Kuta District has a variation depth of 0.4 – 15 meters, North Kuta District has a variation depth of 1.5 – 5 meters, Kuta District has a variation depth of 1.5 – 10 meters, Mengwi District has a variation depth of 1.5 – 10 meters, Abiansemal District has a variation depth of 5-15 meters, Petang District has a variation depth of 5-22 meters. The 3D Zone 1 lithology map can be concluded that Zone 1 area covered with hard soil depth around 5 – 10 meter is dominated by sandy silt, silty sand, sand and a little clayey silt. That area covered with hard soil depth about 1.5 – 5 meter is dominated by clay, clayey silt, sandy silt, silty sand and sand with heterogeneous distribution. The Zone 1 area is dominated by the specific volume saturated value (γsat) range of 1.5 – 2.0 t/m3. The values > 2.0 t / m3 is found in Sading area with hard soil depth of 5-10 meters. The Zone 1 area is dominated by the range of N-SPT values = 0 - 30. The N-SPT values > 30 are found in Sading area with hard soil depth 5-10 meters.

The construction of the Serang – Panimbang Toll Road Section III faces the challenge of surplus excavated material dominated by clay shale from the Bojong Formation. This material is categorized as highly plastic clay (CH) with high swelling and shrinkage potential, so it does not meet the specifications as fill material without special treatment. This study aims to evaluate the effectiveness of stabilizing the excavated soil using calcium carbonate (CaCO3)-based lime. The research method was conducted experimentally in the laboratory with variations in lime content additions of 6%, 7%, and 8% to the dry weight of the soil. The tests included physical properties (Atterberg Limits, Specific Gravity) and mechanical properties (Standard Proctor, CBR Soaked, Unconfined Compressive Strength/UCS, and Swelling). The results showed that the original soil had a Plasticity Index (PI) of 61.17% and a very high swelling potential of 6.92%. Stabilization with CaCO3 proved to be effective in improving soil characteristics. The most optimal decrease in PI occurred at a variation of 7% (to 47.63%), but the best improvement in mechanical properties was achieved at a variation of 6%. At a 6% concentration, the soaked CBR value increased from 0.498% to 1.549%, the unconfined compressive strength (qu) increased to 2.681 kg/cm², and the swelling potential decreased dramatically to 1.26%. Thus, a 6% addition concentration is recommended as the optimum variation for soil stabilization at the study site.

Differential settlement in the transition zone between embankment segments and rigid structures such as Slab-on-Pile is one of the most critical issues in toll road construction on soft soil, as it may reduce ride comfort, safety, and service life. In the Serang–Panimbang Toll Road Section III Project, the applied ground treatment method consists of Free Draining Granular Material (FDGM) supporting the approach embankment and bored piles as the abutment foundation for the Slab-on-Pile system. This study aims to evaluate the performance of the existing treatment method by comparing settlement predictions derived from one-dimensional analytical methods (Terzaghi’s theory for embankments and the Boussinesq and Poulos–Davis methods for abutments) with two-dimensional numerical modeling using PLAXIS. The resulting settlement profile in the transition zone is then analyzed to assess the potential for differential settlement with respect to the applicable serviceability limits. The validation results show a strong agreement between analytical and numerical methods, with settlement deviations of 6.09% for the embankment and 4.93% for the abutment. Nevertheless, the embankment over FDGM experiences a total settlement of 51.90 cm, while the Slab-on-Pile abutment settles only 6.10 cm, producing a differential settlement of 45.80 cm, far exceeding the allowable limit. These findings indicate that the use of FDGM alone is insufficient to accommodate the high compressibility of the thick soft soil deposit at the study location.
