Abstract

Abstrak Cerucuk ferosemen merupakan salah satu ide yang bisa dijadikan alternatif mengatasi permasalahan tanah lunak akibat rendahnya daya dukung terhadap beban di atasnya. Penelitian ini bertujuan untuk menganalisis kapasitas model cerucuk ferosemen terhadap beban aksial di atas tanah lunak ditinjau dari batas penurunan maksimum 2,54 cm. Terdapat 3 macam kondisi pengujianyaitu cerucuk tunggal berlubang, cerucuk tunggal tertutup dan cerucuk kelompok tertutup pada ujungnya (4 buah silinder). Variasi pengujian cerucuk tunggal berupa lama waktu di dalam tanah lunak, yaitu 1, 3, 7, dan 14 hari. Hasil pengujian dibandingkan dengan perhitungan teoritis.  Deformasi dan tegangan tanah lunak dianalisis menggunakan metode elemen hingga. Hasil pengujian menunjukan bahwa kapasitas terhadap beban meningkat seiring dengan bertambah lamanya perendaman. Pada variabel 14 hari, kapasitas maksimum cerucuk tunggal berlubang sebesar 0,80 kN dan meningkat drastis pada cerucuk tunggal tertutup sebesar 3,53 kN terjadi peningkatan signifikan sebesar 77,33%. Sedangkan kapasitas cerucuk kelompok tertutup memiliki kapasitas sebesar 9,91 kN. Kata kunci: Cerucuk ferosemen, tanah lunak, kapasitas dukung (q ultimit), faktor aman, FEM (Finite Element Method).  Abstract Ferrocement pile is an idea to overcome the problem of soft soil which has a low bearing capacity to the load.. This study aims to analyze the bearing capacity of the ferrocement pile model against axial loads on soft soil in terms of the maximum settlement limit of 2.54 cm. There were three conditions of testing: single pile with a hollow at the bottom, single pile closed at the bottom, and group pile closed at the bottom. The variations of the test were the length of immersed in soft soil, namely 1, 3, 7, and 14 days. The deformation and stress were analyzed using a software of FEM (Finite Element Method). The test results show that the capacity of ferrocement pile to the load increases with the increase in the duration of immersion. In the 14-day variable, the maximum capacity in a single hollow ferrocement pile was 0.80 kN and increased significantly in a single closed ferrocement pile of 3.53 kN, or 77.33%. Meanwhile, the group closed ferrocement pile had a capacity of 9.91 kN. Keywords: Ferrocement pile, soft soil, bearing capacity (Q ultimate), safety factor, FEM (Finite Element Method).

Abstract

Abstrak Tujuan penelitian adalah melihat pengaruh penambahan bahan difa soil stabilizer terhadap daya dukung dan potensi pengembangan tanah lempung. Tanah lempung berasal dari Lampung Selatan, dibagi menjadi lima variasi penambahan bahan tambah: variasi 1 (tanah asli), variasi 2 (tanah asli ditambah 8% semen dan 0% difa), variasi 3 (tanah asli ditambah 4% semen dan 3% difa), variasi 4 (tanah asli ditambah 6% semen dan 3% difa) dan variasi 5 (tanah asli ditambah 8% semen dan 3% difa). Untuk pengujian CBR, setiap variasi diberikan empat perlakuan yaitu pemeraman empat hari, pemeraman tujuh hari, pemeraman 14 hari, dan pemeraman empat hari dilanjutkan perendaman empat hari. Sedangkan untuk pengujian potensi pengembangan, benda uji direndam selama empat hari sebelum dilakukan pengujian. Hasil penelitian menunjukkan penambahan difa soil stabilizer meningkatkan nilai CBR tanpa atau dengan rendaman untuk semua perlakuan dan menurunkan potensi pengembangan lempung. Dengan demikian dapat mengurangi ketebalan lapisan pondasi struktur perkerasan jalan. Kata kunci: difa soil stabilizer, sifat mekanik, stabilisasi, tanah lempung.  Abstract The objective of this study was to investigate the effect of difa soil stabilizer on the bearing capacity and swell potential of clay. The clay was divided into five variations: variation 1 (clay only), variation 2 (clay plus 8% cement and 0% difa), variation 3 (clay plus 4% cement and 3% difa), variation 4 (clay plus 6% cement and 3% difa) and variation 5 (clay plus 8% cement and 3% difa). For the CBR test, each variation was given four treatments, namely four-day curing, seven-day curing, 14-day curing, and four-day curing followed by four-day soaking. As for the swell potential test, the specimens were soaked for four days before testing. The results showed that the addition of difa soil stabilizer increased the CBR value without or with soaking for all treatments and decreased the clay swell potential, thereby reducing the thickness of the foundation layer of the pavement structure. Keywords: clay, difa soil stabilizer, mechanical characteristics, stabilization
