<![CDATA[Underground cable distribution channels to be excellent especially in big cities like Jakarta. This is because the underground cable distribution is a solution to the difficulty of land acquisition that will be used for top cable networks. Nevertheless, there is an important factor to be considered in implementing the underground cable distribution channel that is the condition of the soil through which the cable. This study aims to determine the dimensions of the cable house was safe from the soil instability. The soil instability are the stability of bolsters and the shear stability and take into account the carrying capacity of the foundation used. The data used as a reference in the analysis using research data that has been done previously. In stability analysis and foundation bearing capacity used Geo5 software demo version aid. The results obtained from the analysis, with variations on the dimensions of the cable house used are 2 mx 2 m, 2.5 mx 2.5 m and 3 mx 3 m, it is seen that the greater the dimensions used then the security number of stability bolsters, soil shear stability and the carrying capacity of the foundation decreases. This is due to the greater the dimensions of the cable house used, the greater the burden borne by the soil.]]>

<![CDATA[Cikapundung River Restoration lies in a river border with a steep sloping slope and waves to the west - east which is formed from the flow of the river cikapundung. Generally, the soil structure of the Cikapundung River Basin slope is residual ground, corrosion stone and colluvial deposition,which caused vulnerable to landslides. It was also separate and able to keep water. Therefore, shear strength is weak, especially if water is saturated. In this case landslides always occur when it rains. In general, this is due to high rainfall with a certain duration, thus causing the stability of the slope is disrupted. Another cause is the non-functioning drainage system because it is covered by some material from the slopes submitted by water. Therefore, the water rubs the slope.]]>

<![CDATA[The danger of buckling and instability structures easily occurs on the steel beam structure, it will make the structure fails before it reaches the cross section ultimate capacity.In that case the strength of a beam is not only determined by cross-section ultimate capacity. The instability of the structure causes lateral torsional buckling eventhough there is no torque on the beam. There is one way to support the stability of the beam; by installing lateral support on its side. This research is intended to obtain information about flexural strength by comparing the theoretical results based on SNI 03-1729-2002 and (Indonesian National Standard Draft) RSNI 03-1729.1- 201x with the results of experimental testing and finite element analysis results (using the ABAQUS program). The flexural specimens which are studied are in the long-span with a length of 3.3 meters span test. The loading uses three-point load system. The results of the test show information that flexural strength for the long-span specimen from experimental test results has the smallest difference of 33.18% of the theoretical result. As for analysis with FEM also hasthe same difference of 33.18% with the experimental results. Failure that occurs for long-span specimen is due to lateral torsional buckling failures.]]>

<![CDATA[Surface of highway pavement is wet during rain and drowned by stormwater. This situation can makes slip of vehicle wheels and causes an accident. Porous asphalt is a new generation in flexible pavement. Porous charactheristic can be obtained by using less fine aggregates comparing the normal one so it has more voids. We can expect the pavement has higher skid resistance and its voids can be functioned as drainage in mix. This type of pavement developement also strongly depends on availability of the approriate local material for that we can produce a good performance porous asphalt which is described in this paper. Consideration of so many problems can be taken apart, the research is limited in modification design of asphalt concrete wearing course using porous asphalt mix exploits South Sumatera aggregates. After investigatives classification of aggragates, the fine aggregates (sand) can be reduced significantly to obtain a large amount of voids by 6.1% asphalt used. However, this porous structure also causes defect, mainly the stability degradation in mix. So the future research will continue to formularize a better stability performance from pavement variety expected]]>
