Abstract

The Lake Toba boundary area has complex geological and geomorphological characteristics due to past volcanic activity. Along with the rapid development of infrastructure and settlements in this area, in-depth geotechnical studies are needed to support safe and sustainable planning. This study aims to evaluate the maximum shear modulus (Gₘₐₓ) of soil based on Standard Penetration Test (SPT) data with an empirical approach using the formula of Hardin & Black (1968). The study location is in Nainggolan, Samosir Regency, North Sumatra. Analysis was conducted on field data in the form of N-SPT values, soil unit weight, and calculations of effective stress and effective octahedral stress. The results show that the Gₘₐₓ value tends to increase with depth, with the highest value of 60,820.13 kN/m² at a depth of 14.45–16.45 meters, and the lowest value of 14,383.66 kN/m² at a layer of 4.45–6.45 meters, indicating a weak soil zone with high pore water content. Layers with high Gₘₐₓ values are recommended as the main supporting layer of the foundation, while layers with low values require reinforcement. This study proves that the empirical correlation approach based on SPT can be a practical and economical alternative in estimating soil dynamic parameters, and can be used to support civil engineering planning and geotechnical risk mitigation in the Lake Toba area.

Abstract

Infrastructure development often faces challenges due to soft soil conditions, as encountered in the Binjai-Pangkalan Berandan Toll Road Construction Project at STA 38+825. Soft soil has low permeability, low bearing capacity, and a long consolidation period, making soil improvement necessary before construction. One commonly used method is preloading, which involves applying an initial load with temporary embankments to accelerate the soil consolidation process. This study aims to analyze the effect of the preloading method on the acceleration of soil consolidation time and the magnitude of soil settlement at the project site. The analysis was conducted using an analytical approach based on field soil test data, such as boring log data, Standard Penetration Test (SPT) data, and other soil parameters. The calculations were performed using Terzaghi’s One-Dimensional Consolidation Theory. The results show that the preloading method can accelerate the soil consolidation process to achieve 90% consolidation in 249 days. The total settlement observed during the preloading process was 65.246 cm. These findings indicate that the preloading method is effective in soft soil conditions to improve soil stability before the main construction phase begins.

Abstract

Sesuai dengan UU lalu lintas No. 22 tahun 2009 dinyatakan bahwa : 1]Para setiap pengguna jalan harus dapat mengetahui, memahami serta   menjalankan segala peraturan yang telah ditetapkan dalam UU lalu lintas , agar terwujudnya keamanan ,keselamatan lalu lintas  dan terhindarnya  kemacetan  dijalan raya. 2} Masalah lalu lintas  juga merupakan masalah yang berhubungan dengan transporatasi diperkotaan. 3} Terjadinya kemacetan dijalan raya  salah satu pemicu   disebabkan kurang pengetahuan tentang peraturan dan UU lalu lintas, disiplin berlalu lintas  sering diabaikan   pengguna jalan tentu bila dibiarkan akan menimbulkan  meningkatnya tingkat kecelakaan . Isu tentang pentingnya pemahaman  keselamataan berlalu lintas  perlu ditingkatkan  [1] Bagaimana meningkatkan pengetahuan masyarakat atau  siswa tentang keselamatan berkendara dijalan raya. [2] Bagaimana meningkatkan pengetahuan  siswa tentang marka ,  rambu lalu lintas serta bahaya jika melanggar. [3] Bagaimana meningkatkan pengetahuan siswa tentang kelengkapan keselamatan berkendara (safety equipment) serta cara penggunaan yang benar dan resiko jika tidak menggunakannya. [4] Bagaimana meningkatkan pengetahuan  siswa tentang Perilaku aman,/selamat dalam berkendara (safety attitude) serta penerapannya dan resiko jika tidak melakukannya.  [5] Bagaimana meningkatkan pengetahuan  siswa tentang potensi kecelakaan dijalan  raya  (Zero acident) dalam  berkendara. Disertai  contoh dan  tanda kerusakan pada kendaraan meliputi tindakan pencegahan dan perbaikan. Dan dengan memberikan kuesioner  selama pelaksanaan PKM  secara keseluruhan mereka menyatakan puas dan penyuluhan  masih perlu dilakukan  berkelanjutan.
