Abstract

Tanah ekspansif sering menjadi masalah dalam konstruksi jalan dan bangunan. Siklus kembang susut dapat merusak perkerasan jalan dan fondasi. Di daerah Dusun 3 Umbul Lioh Desa Palembapang, Kalianda terjadi masalah ketika musim hujan tiba, yaitu tanah menjadi lunak dan daya dukungnya menurun, yang dapat menyebabkan masalah dalam pelaksanaan konstruksi. Oleh karena itu, diperlukan usaha untuk memperbaiki tanah tersebut. Perbaikan tanah yang dilakukan yaitu dengan mencampurkan pasir bergradasi baik dengan variasi persentase mulai dari 4%; 8%; 10%; 12% dan 16%. Penelitian ini penting karena menguji perbaikan tanah dengan material bergradasi untuk meningkatkan stabilitas tanah. Berdasarkan hasil uji sifat fisik, tanah diklasifikasikan dalam kategori AASHTO sebagai A-7-5, yang termasuk jenis tanah dengan kategori buruk. Sementara dalam klasifikasi USCS, tanah ini termasuk dalam kategori OH atau MH. Penambahan pasir pada tanah lempung dapat memperbaiki sifat fisik, seperti menurunnya nilai indeks plastisitas dan batas cair, sehingga dapat menurunkan potensi pengembangan. Kadar air mengalami penurunan saat terjadinya penambahan pasir. Perubahan distribusi ukuran partikel tanah dapat memengaruhi aktivitas tanah dan kembang susut saat adanya perubahan kadar air.

Abstract

Soil or subgrade is the place where the construction made by technicians for personal and collective interests stands. Before starting a construction, soils that have low bearing capacity, water absorption and high plasticity can be stabilised by soil stabilisation methods. Soil stabilization may involve the use of chemical stabilization materials. This research aims to determine the effect and get the appropriate comparison of the results of the addition of a mixture of fly ash, bottom ash and silica. This research study was conducted using soil samples from Kalianda subdistrict and stabilization materials in the form of fly ash, bottom ash and silica matured for 24 hours. Tests were conducted at the Soil Mechanics Laboratory and physical and mechanical properties were tested.. Clay soils classified as A-7-5 (AASHTO) and OH (USCS) mixed with 4 different compositions of stabilising materials had different results. Of the 4 compositions, the mixture that has the largest bearing capacity value is only silica. Because the results of the CBR test on the mixture that added silica were greater than the mixture using only fly ash and bottom ash. Fly ash, bottom ash and silica gel are easily found or affordable, but the use of silica can increase costs due to its relatively expensive price, inversely proportional to the very affordable price of fly ash and bottom ash.

Abstract

A landslide event occurred in Sukarami, Lahat Regency, in early 2024. This study investigates the landslide mechanism, analyzes the influence of groundwater level rise and load on slope stability, and proposes a management concept. The methodology employed a landslide survey, soil investigation, and limit equilibrium-based stability analysis. Field investigations and surveys revealed that the landslide resulted from a decrease in the shear strength parameter of the surrounding soil layer triggered by rainfall and road drainage runoff. The slip plane, located within a soft to medium consistency clay layer, exhibits high susceptibility to water-induced instability. Numerical simulations demonstrated a negative correlation between groundwater level and slope safety factor, particularly when the water table reaches the critical slip plane. The implementation of a combined gabion, DPT, and minipile reinforcement system can enhance slope stability and elevate the safety factor to meet established standards. Notably, the addition of vehicle loads up to 30 kN/m2 exerted an insignificant influence on slope stability.

Abstract

A landslide that occurred on May 24, 2024, in Pekon Datarajan, Ulubelu District, Tanggamus, Lampung, caused significant disruption to provincial road access and resulted in material losses. This study aims to assess the post-failure slope stability through field geotechnical investigation and numerical analysis using the Limit Equilibrium Method (LEM), and to propose immediate countermeasures. The slope materials consist of MH (inorganic silt) and ML (elastic silt) with high moisture content and moderate to high swelling potential. The lithology is dominated by montmorillonite clay, which has hygroscopic characteristics, making it highly vulnerable to water infiltration that reduces shear strength and increases the risk of slope failure. Stability analysis indicates a post-failure factor of safety (FoS) of 1.36 (static loading) and 1.03 (dynamic loading), which decreases to 1.07 beneath raised groundwater conditions. Recommended immediate mitigation includes surface runoff control, the construction of impermeable drainage systems, the sealing of cracks using impermeable materials, and the installation of temporary slope reinforcements such as sheet piles. The implementation of these measures increased the FoS to 1.61 (static loading) and 1.16 (dynamic loading). This study provides a technical basis for the rapid and effective mitigation of landslides in areas with similar geological and hydrological conditions.

Abstract

Palembapang, South Lampung requires proper road construction for public transportation needs. However, the road conditions in the village were found heavily damaged because of poor soil conditions. Therefore, soil stabilization must be carried out. The method of this study is deep soil mixing (DSM), which is soil improvement method by mixing additional materials in the field (in-site). This method is more affordable because they use their soil as theiraggregate and reduce the transportation budget because of stuff supply.The purpose of this study is to determine the change of soil load-bearing capacity due to the variation of distance and the diameter of the DSM stabilization column on soft clay soil and soft clay soil with 8% lime. This study shows that the stabilization of soft clay soil with 8% lime has increased its load-bearing capacity (qu) from 10.368 kg/cm2to 14.69 kg/cm2. The increase of soil load-bearing capacity with the stabilization of the DSM column is proportional to the volume of soil improvement. The largest increase of the soil load-bearing capacity occurred in 1D columns range and 3.75 cm diameter. The distance variation also gives a more significant change compared to the variation of diameter. The most efficient distance and diameter are at the variation of the distance of 1.25D columns range and 2.5 cm diameter.

Abstract

In embankment planning, it is necessary to consider the influencing factors such as the materialfor making the embankment, slope stability, guard height, slope protection, the width of theembankment, the slope and dumping facilities. Some areas in Indonesia do not have good qualitysoil. For instance, the soil in Palembapang Village, Kalianda, South Lampung. Regarding theissues, soil maintenance is mandatory to be done to increase the physical parameters of the soil sothat the carrying capacity of the soil is maintained. The results shows that at the mixture rate of0%, 4%, 8%, 12% and 16%, the lime is classified as CL (clay low plasticity)which indicates nonorganicclay with low to medium plasticity. The lab testing result of the sample of natural soilshows cohesion value of 0,1813 kg/cm2 and shear angle value of 20o. After stabilizing processwas done using additives, the cohesion value and shear angle value were significantly increasing.It proves that lime can increase soil density as both value increased. In the natural soil sample,the value of the safety factor was still below the safe limit. Another lime additive was added to thesoil sample with lime addition of 16%. None of the safety factor limits were below average afterthe process. In conclusion, lime additive can decrease the plasticity (liquid limit and plasticityindex), enhancing strength and durability, reducing water absorption and soil development aswell as strengthening the stability of the embankment.
