Abstract

Laterite soil is used to support the development of transportation infrastructure such as roads. The use of geotextile as soil reinforcement material is one of the geotechnical engineering practices. The use of geotextile material and lateritic soil for pavement reinforcement requires parameters from lateritic soil and its interaction with geotextile. Planning and implementation work in the field normally use the ratio interface friction angle soil and geotextile friction angle (  /  ), where   is value of interface friction angle between geotextile and laterite (  ) and  is value of angle of internal friction laterite (  ). The ratio (  /  ) was obtained from direct shear test method ASTM D 3080-70. The laterite soil was compacted using a test proctor at a maximum density condition or with a value of optimum water content. The laterite soil came from two locations in Central Kalimantan province distinguished by the closer proximity to the City of Palangka Raya. The geotextile was is Geo- reinforcement HRX 250 and HRX 300. The result showed the value of the ratio  /  for Palangka Raya laterite soil based on two samples of different geotextile types. For the woven geotextile reinforcement HRX 250 (fine), the value  /  was 0.81 to 0.90, and for the woven geotextile reinforcement HRX 300 (rather coarse), the value  /  was 0.75 to 0.77. The ratio  /  is not significantly influenced by the geotextile mass, strength and elongation values. It is the soil types and characteristics that actually influence this ratio

Abstract

During this time to get the value of California Bearing Ratio (CBR) planners will conduct field tests and/or laboratory tests. This takes time and is relatively large. For this reason, it is needed a practical matter or formulation about the relationship between soil parameters so that planners do not need to test the overall soil parameters. This study aims to obtain a graph or correlation of the Plasticity Index (PI) with California Bearing Ratio (CBR) for clay soils in the Palangka Raya region. Clay soil samples were taken at 3 (three) locations in the City of Palangka Raya. Based on the results of tests on several samples obtained the largest CBR value in soil samples from Tangkiling village which reached a value of 6.56%. While the lowest CBR value obtained from the village of Kereng Bengkirai is 3.14%. For the PI value, the biggest value obtained in Bukit Rawi village is the largest, namely 20.54% and the smallest PI value obtained in Tangkiling village is 9.01%. In general, it can be concluded that the CBR value of clay is inversely proportional to the value of PI. Wherein it is known that the greater the CBR value, the smaller the PI value and vice versa. The overall correlation results of the PI value (plasticity index) to the CBR (California Bearing Ratio) obtain the correlation results using the linear graph CBR = -0.28383 PI + 8,9843. While the correlation value based on analytical calculations obtained CBR = -0,3006X + 9,0190. This test shows that the correlation value has a very high relationship when viewed from the benchmark correlation results (R = 0.80-1.00). The results of the correlation value using linear regression graphs worth R = 0.8489 and using analytical correlation methods worth R = 0.9283. So the final result of this study is to look for a relationship between PI values ​​and CBR values. Then for the value of R is taken the smallest value that is R = 0.8489.

Abstract

Soil bearing capacity is the ability of the soil to support the foundation load acting on it. To produce an accurate bearing capacity, it is necessary to know the properties and characteristics of the soil. For this reason, a comparison of the carrying capacity of the soil is carried out based on the calculation of CPT / Sondir and SPT to be able to plan a safe and economical pile foundation. The purpose of this study was to determine the amount of soil bearing capacity of the deep foundation in the environment around the Ataqwa Mosque, Baringin Village, Palangkaraya City based on field tests, and based on laboratory tests, and to determine the value of the comparison between the Mayerhof Method and the Schmertmann-Nottingham Method. Based on the Sondir value, it is continued with the calculation of the carrying capacity of the soil, then the calculation results are analyzed and concluded. From the calculation of the value of the carrying capacity of the foundation pile implementation of point 1 (one), the highest value of 400 mm diameter piles in the Meyerhoff method is 75,319 kg, while the lowest bearing capacity value is also at 400 mm piles of 10,676 kg. For point 2 (two), the highest value is obtained at 400 mm diameter piles in the Shmertmann-Nottingham method of 65,853 kg, while the lowest bearing capacity value is also at 400 mm piles of 10,676 kg

Abstract

Palangka Raya is a city where almost a part of the area is peatland with peat water with an acidity level of around 4.0 - 5.0 which can make concrete become porous and cause damage. This study is to determine the effect of peat water, Kahayan river water, and PDAM water on the compressive strength of concrete. In this study, the immersion of concrete samples was carried out for 28 days and 60 days. The measurement results are known that the pH of peat water is 4.0 while the pH of Kahayan river water and PDAM water is 5.0.From the results note that in the 28 days immersion, peat water concrete has increased in compressive strength while concrete in Kahayan river water and PDAM water has decreased in compressive strength. However, during the 60 days immersion the peat water concrete decreased in compressive strength to 20,638 MPa (17.31%). Whereas the Kahayan river water and PDAM water in the 60 days immersion experienced an increase in compressive strength values of 31,687 MPa (26.96%) and 27,696 MPa (10.98%). From these results, it can be concluded that the Kahayan river water with pH = 5.0 does not make the concrete lose its strength and can survive in an acidic environment.

Abstract

Tanah merupakan dasar dari suatu struktur atau konstruksi, baik itu konstruksi bangunan maupun jalan raya. Sifat-sifat tanah yang buruk atau kurang menguntungkan bila digunakan untuk suatu bangunan atau konstruksi antara lain, plastisitas yang tinggi, kekuatan geser yang rendah, dan potensi kembang susut yang besar. Seperti tanah lempung Desa Mintin yang memiliki nilai CBR dan UCS yang rendah karena dominan butiran halus sehingga mudah dipengaruhi oleh air. Guna mengatasi permasalahan yang ada pada tanah lempung ini, akan dicoba stabilisasi dengan menggunakan semen dan ditambah matos sebagai bahan kimia dan diharapkan mampu memperbaiki dan memenuhi syarat teknis. Pada prosedur penelitian ini dibagi menjadi 3 tahap yaitu penelitian awal meliputi analisa saringan, dan indeks plastisitas, setelah diketahui bahwa tanah tersebut tanah berbutir halus maka dilakukan penelitian kedua yaitu menambahkan campuran pasir 50% terhadap berat isi kering tanah kemudian dilakukan pengujian plastisitas (PI) ≤ 10%. Setelah didapatkan nilai PI ≤ 10% maka dilakukan penelitian tahap akhir yaitu penambahan semen 10% dan campuran matos 0, 4, 8 dan12% terhadap berat isi kering tanah pasir kemudian diuji CBR dan UCS. Hasil penelitian menunjukan bahwa stabilisasi semen ditambah matos dapat memperbaiki sifat fisik dan mekanik tanah lempung, pada sifat fisik berat volume, kadar air, berat jenis, dan batas-batas Atterberg mengalami penurunan setelah dilakukan stabilisasi. Sementara, pada sifat mekanik tanah lempung menjadi semakin baik. Dari hasil campuran semen 10% dan campuran 0, 4, 8, dan 12% matos, campuran yang paling baik terdapat pada 4% penambahan matos untuk nilai CBR, sedang untuk nilai UCS campuran yang paling baik terdapat pada 8% penambahan matos.
