Abstract

The development of the BRIN Geodiversity Area in Karangsambung experienced landslides on the Retaining Wall (DPT) in the form of secant piles with a diameter of 60 cm and a depth of 20 m. This study aims to analyze the causes of landslides and provide alternative repair solutions. The research method uses soil data analysis, back analysis of cracked soil conditions, and numerical modeling with Plaxis 2D software. The analysis results show that the cause of the landslide is the formation of cracked soil which results in increased pore water pressure and cohesive soil becoming behaving like sand (loss of cohesion value). This condition causes active soil pressure to increase significantly from normal conditions. Stability analysis shows that the existing secant pile requires a minimum depth of 29.68 m under cracked soil conditions, while the installed depth is only 13 m. Two alternative solutions are recommended: soldier pile with diameter 1 m and depth 45.58 m (SF=1.665) and soldier pile with diameter 0.8 m and depth 22 m reinforced with ground anchor (SF=1.643). Cost analysis shows that soldier pile with ground anchor is more efficient with material cost of Rp 1.36 billion compared to single soldier pile of Rp 3.49 billion. This research contributes to understanding the behavior of cracked soil on slope stability and practical recommendations for handling similar landslides.

Abstract

The research aims to formulate the government's assets disposal decision making and to determine its estimated value. The research type is descriptive analysis using primary data collected from direct observation in the field and secondary data sourced from Satuan Kerja Pelaksanaan Jalan Nasional Metropolitan I Surabaya. This research uses flowcharts, photo documentation, and asset valuation calculations using Depreciate Replacement Cost (DRC) method. The research object are five government vehicles. The results showed that from those five vehicles, three motorbikes and two cars that have various levels of damage, three motorbikes can be disposed and two cars can be repaired. The results of this study are expected to be used for planning the assets disposal and proposing the estimated value of the assets.

Abstract

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.
