PENURUNAN OPRIT JEMBATAN SEMARANG LINGKAR UTARA DAN JEMBATAN KALI JAJAR DEMAK JAWA TENGAH DENGAN PRE-FABRICATED VERTICAL DRAIN

<p><em>Construction on soft soil, often creates problems. The Semarang North Ring Bridge and Kali Jajar Bridge are the Recent soft Marine Alluvium zones located in the Pantura area which have very soft soil characteristics with a depth of more than -30.0 meters this has resulted in a very large settlement due to very small grains, flood, rob, pore water pressure increases so that the shear strength of the soil will be small, the compression is large and the permeability coefficient is small so that if the construction load exceeds the critical bearing capacity, the damage to the foundation soil will occur. To get the increase in soil bearing capacity, it can be achieved by changing the properties of the soil from the shear angle (</em>f<em>), cohesion (c) and unit weight (</em>g<em>). The settlement can be reduced by increasing the cavity density from the compression of the soil particles (Wesley, 1977). Soil improvement takes a long time, aiming to increase shear resistance so that it requires a fast time in this case is to use Pre-Fabricated Vertical Drain (Bowles 1981). The results of the analysis of the pattern of decline and the effectiveness of the use of PVD (pre-fabricated vertical drain) at the Oprit Bridge in the two research locations have the same decrease in the range of the same heap height at (H = 4 meters) there is a decrease of 117.53 cm at 64 months on the bridge. Kali Jajar (STA. 3 + 200) and there was a decrease of 268.94 cm at 37 months at the Semarang North Ring Bridge</em></p>

PENGARUH PENAMBAHAN KAPUR TOHOR TERHADAP SIFAT MEKANIS BATA RINGAN

<p align="center"><strong>Abstract</strong></p><p>Light brick is an alternative material in the construction sector that has an efficiency value, in addition to being lighter than conventional bricks for building loads, lightweight bricks also reduce the use of materials during construction. One of the uses of light bricks is on walls. This is because the walls contribute to the heavy load on the building structure. Along with the development of the use of light bricks, research was carried out on light bricks with quick lime mixture as a substitute for part of the cement on light bricks which refers to the mechanical properties of light bricks which include free compressive strength testing, while the variation of the mixture used is 5%, 10%, 15%, and 20% of the volume of cement used. The results of the compressive strength of light bricks at the age of 28 days, respectively, the variation of the lime mixture 5%, 10%, 15%, and 20% obtained compressive strength of 0.96 Mpa, 0.81 Mpa, 0.43 Mpa, and 0.32 Mpa where compressive strength The maximum is obtained in the lime mixture as much as 5%, is 0.96 Mpa.</p><p> </p>

Analisa Air Bawah Tanah pada Lokasi Tambang Batubara Tanah Laut Kalimantan Selatan

<p> </p><p class="BodyAbstract">The impact of coal mining will produce a reservoir due to cutting and excavation from the mined area. If it is left without any effort to improve the environment due to mining it will have an impact on the surrounding environment. Research conducted by the author to determine the effect that occurs with a reservoir due to coal mining in the surrounding area. Based on measurements using the geoelectric method, it can be seen the condition of the soil layer in the reservoir and surrounding areas so that it can be estimated the movement of underground water in the aquifer layer. By using a piezometer around the reservoir it can be seen the change in the level of the underground water level at a certain time and the water level in the reservoir is measured in elevation so that it can be predicted the flow direction that occurs. From the results of the study obtained the underground water level has a greater value than the water level in the reservoir, especially in the rainy season. This activity is the initial stage of the study to determine the effect of the reservoir on underground water conservation. For the next stage measurements are needed throughout the year by installing logers so that data can be recorded automatically digitally and doing model simulations using Modflow software to predict the effect of reservoirs on underground water conservation in the long.</p>

kONSEP IMPLEMENTASI PENGEMBANGAN TOD PADA SIMPUL TRANSPORTASI MODA KERETA API (Studi Kasus: Provinsi Banten, Indonesia)

<p class="FormatUI"><em>A train is a mass transportation means that can carry passengers or goods on a large scale, so that the Indonesian people use it as a means of transportation both within cities and intercity/ Along with this, the train station is the main requirement needed in the movement of the rail transportation mode. Apart from the main function of the station as a place for passengers to get on or off, stations can be developed into centers of urban activities by maximizing the use of space at the station and the utilization of the surrounding space which is integrated with the development of properties high density and other supporting facilities. To realize this, an effort is needed to maximize the potential for station development through the Transit Oriented Development (TOD) approach. The development of TOD at a railway station can create an ideal distance or radius from a transportation node to occupancy, creating lower cost, time and energy efficiency so as to improve the quality of life in urban areas, and it is hoped that it can reduce the maintenance costs of the station itself through additional functions that can generate revenue. In order to optimize the function of railway stations, especially in urban areas, this study was conducted to create a concept for regional development with the concept of TOD based on railway stations. This study used a qualitative approach with the study area located in Banten Province (outside the BPTJ working area), and data collection was carried out using purposive sampling method. The result is a station that has the potential to be developed into a transit-based area in Banten Province is the Serang Station</em><em>.</em></p>

PERANCANGAN EFEKTIVITAS PERBAIKAN TANAH DENGAN MENGGUNAKAN METODE PREFABRICATED VERTICAL DRAIN

<p><em>As a country that surrounded by active volcanoes, Indonesia has a very diverse clay soil content. However, in reality, clay soil is an unfavorable condition for construction activities because of its low-level of stability. Therefore, when the clay soil receives a static load on it, the soil will slowly have a settlement due to the dissipation of pore water. This settlement usually occurs over a very long period of time, thus, it is necessary to do the soil improvement using Prefabricated Vertical Drain (PVD) combined with preloading in order to shorten the time of soil consolidation so that the consolidation process becomes faster. Soil settlement analysis is calculated using two soil parameters derived from the NSPT correlation data and laboratory test data to determine the most efficient soil parameters. Furthermore, a theoretical soil improvement analysis was carried out by comparing Baron's theory and Hansbo's theory and using the Settle3D analysis program. The analysis results show that the calculation of consolidation settlement using soil parameters from laboratory test results has the closest value to the actual results in the field with a efficiency of 91%. Meanwhile, for soil improvement, the most effective PVD design was chosen using the Hansbo theory with a triangular installation pattern and a spacing of 150 cm combined with a gradual embankment.</em></p>
