ANALISIS PERMEABILITAS TANAH YANG DIPADATKAN DENGAN MENGGUNAKAN METODA CUBIC PERMEAMETER
Get PDFAbstractThe development of infrastructure in Indonesia is increasing in various regions such as the construction of reservoirs, dams and other construction. One of the important things that became the basis of development is foundation ground. Therefore, it is necessary to know the type of soil used and the permeable nature of the soil. Soil permeability illustrates the ability of soil to pass water. In this study to determine the permeability of the soil by using a cubic mold and compare the results of soil permeability obtained from compacted soil using the pressure method and the standard method. Soil samples used were from Pamenang village, Pringsewu. Soil taken is disturbed and undisturbed soil samples. The soil was then compacted by a standard method and with a pressure test method at a pressure of 5 MPa, 10 MPa and 15 MPa. Then the permeability test is carried out to get the permeability coefficient. The results of observations in the laboratory show the greater pressure applied to the soil, the smaller coefficient of permeability. The relationship between the permeability coefficient with standard compaction method and the pressure method get the permeability coefficient value so that the pressure is between 5 to 10 MPa. Keywords: Soil, Compaction, Pressure and Permeability. AbstrakPerkembangan pembangunan infrastruktur di Indonesia sedang meningkat diberbagai daerah seperti pembangunan waduk, embung, bendungan dan konstruksi lainnya. Salah satu hal penting yang menjadi dasar dalam pembangunan adalah pondasi tanah. Oleh karena itu, perlu mengetahui jenis tanah yang dipakai dan sifat permeable tanah tersebut. Permeabilitas tanah menggambarkan kemampuan tanah dalam meloloskan air. Pada penelitian ini untuk mengetahui permeabilitas tanah dengan menggunakan mold segiempat dan membandingkan hasil permeabilitas tanah yang didapatkan dari tanah yang dipadatkan menggunakan metode tekanan dan secara metode standar. Sampel tanah yang digunakan berupa sampel tanah yang berasal dari desa Pamenang, Pringsewu. Tanah yang diambil merupakan sampel tanah yang terganggu dan sampel tanah tak terganggu. Tanah tersebut selanjutnya dipadatkan dengan metode standar dan dengan alat uji metode tekanan pada tekanan 5 MPa, 10 MPa, dan 15 MPa. Selanjutnya dilakukan pengujian permeabilitas untuk mendapatkan nilai koefisien permeabilitasnya. Hasil dari pengamatan di laboratorium menunjukan semakin besar tekanan yang diberikan pada tanah maka semakin kecil koefisien permeabilitasnya. Hubungan koefisien permeabilitas dengan metode pemadatan standar dan metode tekanan memperoleh nilai koefisien permeabilitas sehingga tekanan berada diantara nilai 5 sampai 10 MPa. Kata kunci: Tanah, Pemadatan, Tekanan dan Permeabilitas

Analysis of Supportive Lower Structure Building on Overpass Construction In The Sumatera Trans Toll Road
No full textEvery light or heavy load construction recquires a supportive foundation, the foundation must be calculated to be able to guarantee the stability of the building to its own weight, building loads and external forces. Pillar foundation is used as a building foundation when the land under the building does not provide sufficient carrying capacity to carry the weight of the building and its load. This research was carried out on one of the bridges on the Trans Sumatra Toll Road. A pillar foundation is used to the toll road project. The purpose of this research is to determine the bearing capacity of the foundation on the pier and abutment from the results of load on the upper construction. Based on the results of the carrying capacity of abutment is obtained 60 cm diameter of pile with 6 pieces, and the bridge’s pillar is 60 cm of pile 15 pieces. While the main reinforcement diameter is 22 mm as much as 6 pieces, with Ø10 strap and 250 mm distance. Keywords: Foundation, Pillar, Pile, Pile Carrying Capacit

Analysis And Planning of Bored Pile Foundation In Double Train Bridge Way Changes In Central Lampung Regency
No full textIndonesia has considerable coal reserves, but only a few or even very few can be exploited. The potential of coal owned by South Sumatra Province is known to reach around 85% of the total reserves contained in Sumatra, or around 22.24 billion tons. This means that even though mining is maximized to 50 million tons per year, coal will not be mined for 200 years. To maximize the potential of available coal, modes are needed from the train, but for now there is only one mode used to extract coal from it to transport coal from Tarahan - Tanjung Enim or vice versa. So to maximize the coal's potential, the Ministry of Transportation through the Directorate General of Railways plans to build a double track railway line between Tarahan - Tanjung Enim, one of the roads going through the river is needed a bridge to facilitate the train journey to transport the coal. The railroad bridge that was built was located in KM132 in the burial way of Central Lampung Province. In this bridge construction, the carrying capacity of the foundation needs to be analyzed so that it can withstand the burden of the upper structure and the train.From the results of the study showed that the analysis of the carrying capacity of the permit pile of 1700 kN was greater than the maximum carrying capacity that burdened the pile of 1508.93 kN so that it could be concluded that the structure under the bridge was able to withstand the load from the upper structure.

Terbanggi Besar - Pematang Panggang Toll Road Tariff Based On Ability to Pay and Willingness to Pay
No full textTransportation is a very important aspect to stimulate the economy, a region cannot be totally independent in meeting its own regional needs, so that the area needs other regions as a support where one of the connecting infrastructure is a toll road. The Terbanggi Besar - Pematang Panggang Toll Road is one of the 8 Trans Sumatra toll road projects that have entered the construction phase in 2017 which are planned to be operated in 2021. The tariff analysis carried out is based on the Ability to Pay (ATP) and Willigness to Pay (WTP) approach. The average ATP value obtained is Rp 131,638.00 / 100 km and the average WTP value obtained is Rp. 40,989.00 / 100 km. Respondent's ATP value > WTP value indicates that the ability to pay respondents is greater than willingness to pay because users have relatively high income but the utility of these services is relatively low. While the determination of ideal rates is based on the average value of ATP and WTP. Based on calculations, the price of the Terbanggi Besar - Pematang Panggang toll roads tariff is Rp. 86,314.00 / 100 km
