Abstract

The Student Dormitory is a gathering place for most new students at ITERA. For disaster mitigation, it is necessary to conduct geophysical and geotechnical surveys. Geophysical and geotechnical surveys are conducted to describe the subsurface lithology. The purpose of this study is to identify the subsurface of the Dormitory building so that it can be determined which buildings have the potential for geological hazards. The methods used are geomagnetic, geoelectric and geotechnical methods. The results obtained are that High and low magnetic anomalies are related to the thickness of the lithology. This is also justified by the results of geoelectric using resistivity cross-sections. The thickness of this lithology is related to the level of building security. TB4 has the highest security based on magnetic and geoelectric data. Meanwhile, TB1 has the lowest security based on subsurface conditions.

Abstract

Penyusunan kurikulum berbasis Outcome Based Education (OBE) merupakan upaya strategis untuk memastikan ketercapaian kompetensi lulusan yang relevan dengan kebutuhan dunia kerja, perkembangan teknologi, dan tantangan pembangunan berkelanjutan. Sejalan dengan hal tersebut, Program Studi Teknik Sipil Institut Teknologi Sumatera (ITERA) menyelenggarakan Focus Group Discussion (FGD) sebagai wadah kolaboratif dalam merumuskan Kurikulum 2025–2030. Proses ini melibatkan pemangku kepentingan internal dan eksternal, termasuk dosen, mahasiswa, alumni, praktisi, asosiasi profesi, serta pengguna lulusan. Kurikulum yang dikembangkan dirancang sesuai dengan standar Outcome Based Education (OBE) dan kriteria akreditasi LAM Teknik, dengan penekanan pada penguatan kompetensi inti bidang teknik sipil, integrasi teknologi digital, prinsip keberlanjutan lingkungan, serta pengembangan soft skills mahasiswa. Hasil FGD ini menghasilkan rekomendasi kurikulum yang adaptif, aplikatif, dan berorientasi pada capaian pembelajaran lulusan (CPL) yang selaras dengan standar nasional maupun internasional, sekaligus mendukung visi ITERA untuk menjadi perguruan tinggi yang unggul dalam sains, teknologi, dan inovasi.

Abstract

The construction of a structure on soft soil has the potential for structural failure. This phenomenon occurs because the low bearing capacity of soft soil is accompanied by high compressibility, resulting in large settlements and low stability. This problem needs to be solved by soil improvement. In the Indrapura–Kisaran STA 112 + 500 Toll Road Construction Project, soil will be filled more than the ground's bearing capacity. Therefore, a soil improvement method using a Controlled Modulus Column (CMC) is necessary. The analysis method used in this study uses analytical methods and the finite element method (FEM). The analysis was performed by comparing the bearing capacity and settlement in conditions without improvement (preloading) and with improvement using CMC. The installation of CMC with a spacing of 1 meter, a diameter of 0.42 meters, an LTP thickness of 1 meter, and a concrete quality of 16.41 MPa showed an increase in soil bearing capacity of 30%. The rise in ground bearing capacity also affected soil compressibility, resulting in a reduction of up to 68% in soil settlement. Therefore, installing CMC on soft soil effectively increases bearing capacity and reduces settlement. Ground stability is improved, with the safety factor rising to 2.11.
