Abstract

The soil layers in Banjarmasin are generally soft clay soil, whereas hard soil layers are in the range of 30 to 50 matters below ground level. Therefore, deep foundation is the right alternative to build a stronger and more stable construction. This study aims to determine the comparison value of pile bearing capacity based on theoretical and actual result so it can be used to determine the selection for planning and execution in installation of piles foundation. The study was conducted at Lambung Mangkurat University (ULM) Campus, Jl. Brigjend H. Hasan Kayu Tangi, Banjarmasin. This study used mini piles size of 20cm x 20cm with vary in length. The type of soil bearing capacity against piles is friction. In theoretical calculation, it used sondir data while in actual bearing capacity it used the result from loading data test at pile B, E, G and I, then all data processed and analyzed by using methods from Davission (1973), Mazurkiewich (1973), and Chin (1970). The results of the calculation of bearing capacity of the ultimit piles, both theoretical and actual show a very significant difference. A very large difference on pile E4 with a depth of 12 meters of 53,25%, and the smallest difference in pile I with a depth of 12 meters by 15,25%.

Abstract

Dalam makalah ini mendiskusikan mengenai pengembangan fasilitas infrastruktur umum di Komplek Bumi Mas Lestari Perdagangan Banjarmasin yaitu Pembangunan Jalan lingkungan yang secara khusus meninjau bagian tanah dasar dan ketebalan timbunan sirtu. Perhitungan daya dukung tanah dasar mengacu kepada input nilai CBR metode SNI yaitu index dan engineering properties, uji kepadatan tanah standar proctor di laboratorium dan uji CBR Laboratorium. Studi penelitian terhadap tanah dasar yang dibandingkan adalah tanpa dan dengan penggunaan penambahan semen 9% terhadap tanah asli lanau lunak berlempung plastisitas rendah, hasil yang dapat mewakili untuk perbandingan nilai kelayakan subgrade adalah pemenuhan terhadap ketentuan nilai CBR subgrade pada Spesifikasi Umum Bina Marga sebesar minimum 6% pada pelaksanaan timbunan jalan, karena antara nilai CBR tanah dasar asli yang dihasilkan 4% dan setelah distabilisasi menggunakan semen menghasilkan peningkatan 9,8%, tanah dasar telah memenuhi persyaratan dan dapat digunakan menjadi bagian dari konstruksi perkerasan jalan diatasnya sebagai penopang. Abstract This paper discuss infrastucture development of road transportation in Bumi Mas Lestari Housing Compex Construction mainly Road access facility construction mainly for subgrade and embankment of thickness materials. The calculation of theoretical bearing capacity of subgrade based on Standar Nasional Indonesia (SNI), including Proctor Standard and CBR test laboratory.research focus on cement mixing between natural condition of subgrade using 9% cement ratio in silty clayey low plasticity type of soil sample. Conduct Bina Marga Specification of Road Construction, minimum CBR Design is 6% was allowed with 9,8% CBR Design after mixing cement as stabilitation of 4% CBR design before.

Abstract

Tanah merupakan salah satu dari sekian banyak material yang bervariasi (heterogen) antara satu lokasi dengan lokasi yang lain., maka dalam penelitian ini melakukan penambahan material pasir putih yang kemudian dicampurkan dengan tanah asli yang berasal dari desa Bangkuang Kecapamatan Karau Kuala Kabupaten Barito selatan. Kegiatan penelitian dilakukan di laboratorium Geoteknik dan Transportasi Politeknik Negeri Banjarmasin meliputi beberapa metode pungujian dilakukan sesuai dengan standar penelitian yaitu: SNI 03-1965-2008, SNI 03-1964-2008, SNI 03-1967-2008, SNI 03-1965-2008,SNI 03-1743-2008 SNI 03-1738-2011, dan SNI 2828:2011. Hasil penelitian, dengan penambahan pasir putih sangat berpengaruh terhadap perbaikan sifat – sifat tanah yang akan digunakan untuk bahan stabilisasi subgredre, maka didapat nilai sifat-sifat tanah diberi bahan pasir putih (0%) meliputi; kadar air (W) 23,87%, berat jenis (Gs) 2,59, batas cair (LL) 33,9%, batas plastis (PL) 20,11%, plastisitas indeks (PI) 13,79%, kadar air optimum (OMC) 18,6%, kepadatan kering maksimum (dMax) 1,61 Gr/Cm3 dan CBR desain 5%. Nilai sifat-sifat tanah diberi bahan tambah pasir putih. Nilai sifat-sifat tanah diberi bahan tambah pasir putih (15%) meliputi; berat jenis gabungan (Gs) 2,62, batas cair (LL) 29,6%, batas plastis (PL) 19,52%, plastisitas indeks (PI) 10,08%, kadar air optimum (Omc) 81,5%, kepadatan kering maksimum (dMax)) 1,54 Gr/Cm3 dan CBR desain 6,1%, berat isi kering (d) 1,538 gr/cm³. Abstract Land is one of the many varied material (heterogeneous) between one site and another location., then in this research performs addition material of white sand is then blended with the native soil that comes from the village of Karau Kuala Kecapamatan District Bangkuang Barito South. Research activities carried out in the laboratory of Geotechnical and transportation State Polytechnic Banjarmasin includes several methods of pungujian conducted in accordance with the standards of research, namely: in accordance with the SNI 03-1965-2008, SNI 03-1964-2008, SNI 03-1967-2008, SNI 03-1965-2008, SNI 03-1743-2008, SNI 03-1738-2011, and SNI 2828:2011. Results of the study, with the addition of white sand is very influential towards the improvement of the nature – nature of the land to be used for subgredre stabilization materials, then obtained the value soil properties are given materials white sand (0%) include; moisture content (W) 23.87%, heavy types (Gs) 2.59, liquid limit (LL) 33.9%, limits plastis (PL) 20.11%, plasticity index (PI) 13.79%, optimum moisture content (OMC) 18.6%, maximum dry density (/dMax) 1.61 Gr/Cm3 and CBR design 5%. The value soil properties are given the added ingredient of white sand. The value soil properties are given the added ingredient of white sand (15%) include; the weight of the combined type (Gs) 2.62, liquid limit (LL) 29.6%, limits plastis (PL) 19.52%, plasticity index (PI) 10.08%, optimum moisture content (Omc) 81.5%, maximum dry density (/dMax)) 1.54 Gr/Cm3 and CBR design 6.1%, weight dry (/d) 1.538 gr/cm ³.
