Abstract

Tanah ekspansif memiliki karakteristik yang sangat dipengaruhi oleh perubahan kadar air, menyebabkan perubahan volume yang signifikan yang dapat merusak struktur di atasnya. Penelitian ini bertujuan untuk meningkatkan stabilitas tanah ekspansif melalui stabilisasi menggunakan kombinasi garam dan semen. Metode yang digunakan meliputi uji laboratorium untuk menganalisis sifat fisik dan mekanik tanah sebelum dan sesudah stabilisasi. Variasi campuran yang digunakan adalah semen dengan kadar 13 persen, 16 persen, dan 19 persen serta garam sebanyak 3 persen, dengan waktu pemeraman selama 3 dan 7 hari. Hasil penelitian menunjukkan bahwa stabilisasi ini menurunkan kadar air hingga 62,50 persen, meningkatkan berat jenis dari 2,36 menjadi 2,59 g/cm3, serta meningkatkan kepadatan kering maksimum. Selain itu, potensi pengembangan tanah yang awalnya sebesar 114,5 persen berhasil ditekan hingga 0 persen setelah penambahan garam 3 persen dan semen 13 persen. Waktu pemeraman juga berpengaruh terhadap efektivitas stabilisasi, di mana pemeraman lebih lama memberikan hasil yang lebih baik. Kesimpulan dari penelitian ini adalah bahwa kombinasi garam dan semen dapat secara efektif memperbaiki karakteristik tanah ekspansif, sehingga dapat diterapkan dalam perbaikan tanah untuk mendukung konstruksi yang lebih stabil dan aman.

Abstract

Learning facilities for students of the Faculty of Engineering, University of Jember (FT-UNEJ) were still insufficient. Fifteen study programs at FT-UNEJ were only served in one lecture building. Additional floors in existing buildings are done to increase the classrooms as a follow to the problem. An additional three floors were made as a classroom and one roof as a meeting room (rooftop). Planning and evaluation were done by modeling 3D buildings in a structural analysis program. Analysis and evaluation in the structural analysis program were modeled with the same dimensions as the existing conditions, and an additional number of floors would be added according to the preliminary design calculations. Modeling results showed the condition of the building plans was still safe. The largest inter-floor deviation value is 10.2 mm which is still below the permit deviation (31.5 mm), and the structural integrity value is -0.97 (requirement -1 <- 0.97 <1).

Abstract

The landslide occurred on the slopes of the Gandong Magetan River. The location of the river in the middle of the city caused landslides to almost reach people's homes. Efforts should to be made to improve slope stability so that it is safe against landslides. Slope stability analysis uses the LEM (Limit Equilibrium Method) with the Geoslope program. The results of the analysis of the slope stability of the existing conditions get the value of the safety factor of 0.379. Alternative reinforcement that is planned is the manufacture of counterweight slopes. Planning of counterweight slope embankment as many as 4 levels with a height of 3 m each level. The results of the counterweight slope stability analysis get a safety factor value of 0.507. The critical area is at the top of the slope so that soil nailing reinforcement is added. The results of the counterweight slope stability analysis with soil nailing and gabion reinforcement obtained a safety factor value of 1.507. So that the slope reinforcement plan is safe against landslides.

Abstract

The Santer Riverbank which is located in Panggul Melati Hamlet, Kepanjen Village, Gumukmas District, Jember Regency, East Java is still used by the community for agricultural land. This research was conducted to create safe agricultural land for the community. Landslides on this riverbank often occur because it is located on the edge of the river and has a steep slope. In the observation in 2022, there is a collapsed riverbank approximately 20 meters in front of the river embankment. To prevent a longer landslide area, the slopes on the river border are optimized so that residents can still use the land safely. The selected reinforcement is made based on the geometric conditions and the results of the SF value from modeling the existing conditions using the Geostudio program. Appropriate reinforcement based on geometric conditions and SF values ​​is a balancing method. close to the counterweight method, the geometric conditions are more optimal with the SF value increasing from 1.099 to 1.623

Abstract

One of the bridge construction projects in Kalimantan was built on soft soil using a piled embankment reinforcement system. The reinforcement used is a combination of minipile and geotextile poles. However, after the landfill was carried out on the bridge embankment, a settlement is occured of approximately 0.6 m in a period of 3 months. Studies are conducted to evaluate and review the causes of decline. In addition, optimization of the design was carried out in this study. Evaluation is carried out by reviewing the bearing capacity of single and group piles of the minipile based on Standart Penetration Tests data. The calculation of load distribution on piled embankments follows the regulation of BS 8006. Deformation analysis is performed with Plaxis 2D program. Based on the analysis results, it was found that the ultimate bearing capacity of the pile group under the embankment was not able to withstand the working load. The settlement that occurred in the bridge's oprit was most likely caused by the collapse of the soil. Based on the consolidation analysis using plaxis, a value of 0.6 m was obtained within 90 days. Based on the evaluation results, the optimization of the design was carried out using the same method, namely using a pile embankment but differed in the dimensions and installation configuration. The design optimization results show that the bearing capacity is sufficient and the resulting average total deformation is 0.0435 m.

Abstract

Fenomena longsor merupakan bencana geoteknik yang sering terjadi di daerah tropis, termasuk Indonesia. Salah satu kejadian longsor yang terjadi pada Jalan Raya Gumitir KM 233+550 pada Juli 2023 mengancam kestabilan lereng yang vital bagi infrastruktur transportasi. Penelitian ini bertujuan untuk menganalisis stabilitas lereng pasca longsor dan membandingkan efektivitas metode perkuatan soil nailing dan gabion. Metode yang digunakan dalam penelitian ini adalah analisis stabilitas lereng menggunakan perangkat lunak geoteknik berbasis Limit Equlibrium Method, dengan data sekunder berupa data boring dan Standard Penetration Test. Hasil analisis menunjukkan bahwa lereng pada kondisi eksisting memiliki faktor keamanan 0,944, yang menandakan kondisi kritis. Setelah perkuatan dengan soil nailing, faktor keamanan global meningkat menjadi 1,917, menunjukkan bahwa lereng berada dalam kondisi aman. Sementara itu, perkuatan gabion menghasilkan faktor keamanan 1,562, yang masih memenuhi kriteria aman meskipun lebih rendah dibandingkan soil nailing. Berdasarkan hasil analisa, dapat disimpulkan bahwa kedua metode perkuatan efektif, namun soil nailing lebih direkomendasikan untuk meningkatkan kestabilan lereng pada lokasi vital dengan risiko longsor tinggi. Penelitian ini memberikan rekomendasi teknis untuk memilih metode perkuatan yang sesuai dengan kondisi lapangan dan tingkat risiko, dengan mempertimbangkan faktor keamanan, efisiensi, dan keberlanjutan.
