Abstract

Percepatan pembangunan di bidang infrastruktur adalah kebutuhan saat ini, termasuk masa konstruksi sebuah jembatan. Salah satu solusi untuk mempercepat masa konstruksi jembatan adalah menggunakan komponen jembatan yang dibuat terlebih dahulu di luar lokasi pekerjaan atau pra-fabrikasi, dibuat dalam ukuran segmen yang masih mudah untuk dimobilisasi dari workshop ke lokasi, kemudian komponen tersebut mudah dirangkai menjadi satu kesatuan, yang akhirnya akan meminimalisasi waktu pelaksanaan di lokasi pekerjaan. Solusi tersebut adalah komponen jembatan modular, salah satunya yang dilakukan oleh Puslitbang Jalan dan Jembatan yang bekerjasama dengan POSCO yang merupakan perusahaan fabrikasi baja dari Korea Selatan, yaitu jembatan Gelagar Boks Baja Modular bentang 40 m dan terdiri dari tiga segmen: 12 m, 16 m, dan 12 m. Ujicoba konstruksi jembatan gelagar boks baja modular dilakukan pertama kali di Indonesia pada tahun 2016, dengan lokasi di Kali Cimanis, Kabupaten Cirebon. Pada umumnya, jembatan gelagar boks baja modular ini dipasang sebagai lintas atas dari sebuah jalan eksisting yang digunakan sebagai tempat untuk sebuah mobile crane melakukan pekerjaan peluncuran gelagar. Dengan lokasi ujicoba konstruksi di atas sebuah sungai dan tidak memungkinkan untuk menggunakan metode yang sama, maka dalam pelaksanaannya, digunakan alternatif metode konstruksi dengan menggunakan dua buah crane di satu sisi sungai yang merupakan lokasi perakitan dan satu buah crane di sisi lain untuk menyambut gelagar. Dalam penelitian ini, dilakukan analisis terhadap metode konstruksi tersebut untuk memastikan pelaksanaan yang dilakukan dapat berjalan aman, komponen struktur tidak mengalami kerusakan, dan pekerjaan dapat berjalan lebih cepat sebagai bagian dari tujuan percepatan pembangunan infrastruktur. Dari hasil analisis setiap kemungkinan dari tahapan konstruksi yang digunakan dalam metode konstruksi alternatif tersebut, didapat hasil bahwa tegangan terbesar yang terjadi akibat pelaksanaan adalah 50,37 MPa, yang kurang dari tegangan ijin 380 MPa. Selain itu, defleksi vertikal terbesar yang terjadi pada tahapan peluncuran gelagar adalah 21,98 mm, yang kurang dari defleksi ijin 50 mm. Sehingga, metode konstruksi ini dapat digunakan dan menjadi acuan untuk metode konstruksi jembatan gelagar boks baja modular untuk lintas atas sungai.

Abstract

Determining the priority of regional road development, especially rural roads, is still using methods objectively appro or by assessing field conditions. Programming of road construction carried out through the mechanism of RPJMDes and RKPDes has not provided a clear picture of the level of rural accessibility. Another method is Technical Guidelines (Juknis) for District Road Planning issued by the Directorate General of Highways. This technical guide generally contains a planning approach based on the calculation of priority scale based on the average daily traffic (LHR), and calculation of the cost-benefit value (Net Present Value (NPV / km). Both methods produce calculations that are more likely to prioritize roads that have a level conditions for severe road damage or high traffic, even though there are areas that need road construction related to the accessibility of the population, such as access to education, health, trade or agricultural centers.To determine whether a village has adequate accessibility of road infrastructure, it is necessary an analysis method that can produce a value (index) for accessibility, one of them is the rural accessibility assessment method issued by the World Bank, namely the Rural Access Index (RAI). RAI uses a calculation method that uses a fixed variable population to access a specific area. Low RAI value indicates that the area is need road access. This study compares the results of the use of three methods for prioritizing rural road development by taking case studies in the Ciwidey Agropolitan Area. The comparison of the three methods shows that the use of RAI is superior to its ability to provide an index (assessment) of the accessibility of rural roads to a specific area needed by the community, such as access to agricultural land in a case study that is associated with the proportion of the population passing through it. Keywords: rural road, road data assessment, priority program, accessibility, RAI.

Abstract

Several studies have been completed to adjust the value of PCE to be more in line with the existing changes in field. This study aims to analyze the speed distribution of two toll road segments and use it to estimate the PCE. This study was conducted using data of flow and speed for inter and intra city, namely Jakarta-Cikampek and Jakarta Outer Ringroad. The result of analysis shows that the speed in these two toll roads followed the normal distribution and the PCE’s values of intra city are greater than inter city. Result of comparison shows that the pce’s values based on speed are smaller than those in MKJI 1997. Keywords: pce, speed, toll roads, intra city, inter city

Abstract

Liquefaction is the loss of soil strength due to an earthquake. Liquefaction usually occurs on the water-saturated soil, pore water pressure increases and the soil loses its bearing capacity ,consequently it can not support heavy structure which cause the building collapses. Padang is an earthquake-prone area that has caused several damage (Earthquake in Padang on September 2009), many buildings and infrastructures have collapsed, its was due to the liquefaction triggered by the earthquake. Analysis and prevention of liquefaction is needed to minimize the impact of the earthquake. This study liquefaction analysis uses the CPT, and the prevention of liquefaction by the cement column method. The results of liquefaction analysis consisting of 10 locations which were observed shows that there were 4 points location of potentially liquefaction, 3 points of hight liquefaction and 3 points that didn’t potentially liquefaction. The cement column method is carried in a laboratory by means, the soil sample is placed in a test box and then grouting by cement with a diameter 2.5 cm, with spacing 2D, 3D and 4D. The test box was vibrated and then shear strength was tested after and before grouting. The results of shear strength test obtained cement column can reduce the potential liquefaction with the spacing is 2D. The shear streght value increas from 3.14 kPa to 16.86 kPa, the shear strength value increased by 537% ,and can reduce the settlement by 500%. The results of this study can be utilized by consultants and the government to guideline development of Padang city. Keywords: soil, earthquake, liquefaction, CPT, cement column

Abstract

The structural strength testing is required to evaluate an existing pavement. The common equipment used for this sort of testing is Falling Weight Deflectometer (FWD. Especially in Indonesia, the availability of FWDs is very limited except in Java island. The alternate equipment for this purpose is to use the IRE’s LWD. This type of LWD is slightly different to that of standard ones, where the IRE’s LWD does not use load cell. The load parameter depends on the height of drops which is calibrated on the laboratory. Another thing is that the IRE’s LWD has higher stress level because its load is higher than the standard ones. This study is to look for the possibility of the use of IRE’s LWD as the alternate equipment for FWD on the flexible pavement as well as to find the correlation between these equipment in terms of surface modulus. The main parameters considered in this study are the surface modulus on the load point (E0) and surface modulus in the 900 mm offset (E1). The site for this study is at IRE campus which is classified as medium to low volume flexible roads. It is found that there is a strong correlation between surface modulus obtained from FWD test and that of IRE’s LWD. This is indicated by the plotting between each modulus around the equality line as well as by their coefficient correlation. This findings assure that it is possible to use the IRE’s LWD as the alternative for FWD for evaluation flexible roads which are classified as the medium to low traffic flexible roads. Keywords: IRE’s LWD, FWD, surface modulus, flexible pavement evaluation, medium to low traffic roads.

Abstract

Fly ash is a coal combustion product from several power plants. Currently, F type fly ash is commonly used for concrete mixes. This study discusses the effect of 100% addition of fly ash on concrete mixes. In this study cement is substituted with fly ash. Laboratory testing is performed by making a physical model in the form of reinforced concrete beams. Test results were compared between geopolymer concrete and conventional concrete. To determine the mechanical properties of concrete, the specimen was made in a cylindrical shape measuring 150 mm x 300 mm and a beam measuring 150 mm x 150 mm x 600 mm. To determine the structural capacity of geopolymer and conventional concrete, two structural beams measuring 150 mm x 350 mm with a length of 4000 mm were made. The testing of structural beams was undertaken according to the ACI 437.1R-07. Then, the laboratory test results are compared to the theoretical analysis. Based on the results it was found that beams strength made of geopolymer concrete is almost equivalent to the conventional concrete. Based on the test results, the load capacity of the geopolymer concrete beam structure of 87.5 kN with a deviation of 38% for theoretical analysis. For conventional concrete, the load capacity is 109.2 kN with a deviation of 25% compared to theoretical analysis. In addition, the structural capacity value of geopolymer and conventional concrete beams based on the results of laboratory tests is smaller than the results of theoretical analysis. Keywords: Portland cement, fly ash, conventional concrete, geopolymer concrete, reinforced concrete beam
