Analisis Stabilitas Lereng Pada Tanah Clay Shale Proyek Jalan Tol Semarang-solo Paket VI Sta 22+700 Sampai Sta 22+775

The aim of this thesis was to analyze the slope stability on clay shale soil and to provide recommendations of design that meet the design criteria with the level of service based on the standard on the project Semarang-Solo toll road. The toll road was built to support economic growth in Semarang, Solo and its surroundings. The location was reviewed in this thesis include a toll road project Semarang-Solo package IV Sta. 22+700 to 22+775. We choose these location because we consider that these sta have the greatest risk of landslides. The data used in this case study were primary and secondary datas. The datas were collected by interview method, observation methode and methods of literature. For analysing in this thesis were by calculate the slope stability and provide alternative solutions to problems that occured. Geotechnical analysis was done in two ways, namely manual and program. Manual analysis used Fellenius method and Bishop\u27s method while analysis finite element method used Plaxis software 8.2. Mohr-Coulomb failure model were chosen as a model soil. The results showed that the catastrophic landslide occurred at Sta 22+700 to 22+775. Changed the geometry of the slope and strengthening with bored pile at two different elevation were tired to produce sliding safety factor 1,433 this value is greater than the safety factor requirement 1,4

Perencanaan Box Culvert Dan Pintu Air Tambahan Pada Pintu Air Manggarai, Jakarta Selatan

Banjir merupakan permasalahan yang sering dihadapi oleh masyarakat Jakarta. Lahan-lahan yang telah banyak berubah fungsi menyebabkan penyerapan air berkurang. Banjir yang sering terjadi di Pintu Air Manggarai, dikarenakan kondisi saluran tersebut sudah tidak memungkinkan menampung air hujan dengan intensitas tinggi. Dengan kondisi tersebut, pemerintah kota Jakarta mengatasi masalah banjir yang terjadi di Jakarta dengan merealisasikan program normalisasi Sungai Ciliwung berupa penambahan pintu air Manggarai. Perencanaan Pintu Air Tambahan pada pintu air Manggarai menggunakan data curah hujan 10 tahun terakhir, data tanah, dan peta topografi Kota Jakarta. Perhitungan debit banjir rencana dengan periode ulang 25 tahun (Q25) sebesar 495 m3/det. Berdasarkan perhitungan debit baru untuk saluran tambahan dikurangi dengan debit banjir saluran lama didapatkan hasil 195 m3/det. Saluran Tambahan pada pintu air Manggarai menggunakan saluran tipe box culvert. Perhitungan struktur box culvert ini menggunakan software SAP 2000 untuk menentukan ukuran tulangan yang digunakan. Dari hasil perhitungan didapatkan dimensi box culvert tinggi 10 m, lebar 8,6 m dan tinggi jagaan 1 m. Pintu air dengan tinggi pintu 7 m dan lebar pintu 7 m. Pembangunan konstruksi Pintu Air Tambahan Manggarai memerlukan waktu 46 minggu dengan total anggaran sebesar Rp 28.182.870.000 (dua puluh delapan milyar seratus delapan puluh dua juta delapan ratus tujuh puluh ribu rupiah)

Analisis Longsoran Ruas Jalan Cening Kecamatan Singorojo Kabupaten Kendal Jawa Tengah

This Final Project contained about land stability and it countermeasures on roads Cening Sub-district of Singorojo District of Kendal Central Java. This road crosses the hills with unstable soil conditon. Based on the soil drilling test result, it's contain of clay, clay stone ( splinter ), and clay stone ( clay shale ) layers. This Final Project analyzes value of the slope safety factor that included a condition when occured of the movement of soil slopes which is caused by instability on slopes due to degdradation of soil layers, manual calculation of slope stability using Fellenius method and Plaxis V.8.2 computer program. Based on the to manual calculation of slope stability using Fellenius method,it's obtained value of the slope safety factor equal to 1,074 and use Plaxis software obtained value of the slope safety factor equal to 1,081. Those values of the slope safety factor are still less than slope stability regulation equal to 1,5, with the result that the slope condition is prone to landslide. The Analysis result indicate that reinforcement slope with bored pile with diameter of 0,55 m in depth of five meters which is placed at the bottom of the slope, it's the alternative handling had increased the value of the safety factor with the factor of safety of the existing condition which is from 1,081 become 1,812

Perencanaan Jembatan “Berdikari” Kali Garang

This final project consists of redesign of Berdikari-Kali Garang Bridge by using Prestressed Box Girder Concrete. The construction method that is used in this project is segmental box girder. And for the prestressed system, the type of cantilever is based on the consideration of the length of this bridge which has 240 meters length, and is devided into 3 quarters, which are : 60 m + 120 m + 60 m. The design of this bridge begins with the explaination of the background for the choice of the bridge type, the purpose for this study is followed with the fundamental of design, which is analyzed is based on the BMS '92. from the original data, the preliminary design is done by determining the main dimension of the bridge. In the initial phase, the design of load analyzed are used. Load analyze are self weight, dead load, additional weight, traffic load, and time analyze because of creep, and loss of prestressed. From the analyze, than did the allowable stress control. After, did the box reinforcement calculation, allowable deflection, shear calculation, strength and stability calculation which are crack moment control, limit moment, divided force, and torque. At the end of design stage is did the support design. Upon completion stage box, then do the structural design under the initial step to determine cross-sectional dimensions of the pillars and abutments plan which will be calculated ultimate load that will be used to analyze the strength of pillars and abutments. Recent stages of planning the foundation pillars and abutments. The end result of this planning and cross section shape. Where that will be calculated from the price of the building to be used

Analisis Stabilitas Lereng Boja – Darupono Sta. 10+720 Jawa Tengah Dan Usulan Penanganannya

The landslide occurred on road Boja – Darupono Sta. 10+720 created a long traffic jam and holding up economic development between Kendal and Semarang. By analyzing the slope stability by using Fellenius method, it is shown that the SF or safety factor of the slope is 1,19 for the radius of the circle ( R ) = 28,67 and 1,63 for R = 27,09. While SF on a Plaxis V.8.2 program is 1,19, so it can be concluded that the slope in critical condition because of the SF on Plaxis V.8.2 program smaller than that of 1,5 safe although the safety factor on Fellenius value is greater than the value of safe SF. The first alternative of slope reinforcement is a Bored pile, the second alternative is Geotextille with a Counter weight. Based on finite element method calculation using Plaxis V.8.2 program, reinforcement with Bored pile produce SF = 1,75 and Geotextille with a Counter weight SF = 1,5. This form these two alternatives, Bored pile reinforcement has the greatest, so can be considered as the best alternative solution

Perencanaan Jalur Ganda (Double Track) Jalan Rel Ruas Semarang – Gubug

Based on National Railways Master Plan (RIPNAS) of Directorate General of Railways Ministry of Transportation (2011), in 2030, number of railway pessangers in Java increased in the amount of 858.5 million people / year and freight in Java amounted to 534 million tons / year. Therefore, the government planed to develop the railway network in Java with Double Track program or multiple pathways in order to achieve optimal service, the development of a single track to double track between Semarang Tawang Station in Semarang until Gubug station in Grobogan were included. From the design performed, the double track alignment will be placed on the right side of the existed alignment in direction from Semarang to Gubug where there are more open land availability, with the new lines elevation as high as the existed lines elevation. Railway constructed in accordance with the first class railway classification with R54 rails type, double elastic\u27s fastening system using Pandrol e-clip type with rubber pad, PT.WIKA Beton prestressed concrete sleppers N-67 type , upper ballast thickness of 30 cm and 15 cm thick sub ballast. Double track railway\u27s subgrade situated more on the fill positions between 30 cm to 165 cm height using retaining wall reinforcement. Side channel surface drainage with a rectangular cross section from reinforced concrete
