<![CDATA[The Rawabuaya flyover bridge is an option to overcome the traffic jam that often happens in the Rawabuaya area. It has an extremely vital function to disentangle the traffic congestion; therefore, the structure must be strong in holding the on-going load, specifically the seismic load. The seismic load is dangerous to a structure because it has period that causes the structure to repeatedly shaken. If the movements happened continually, the structure will collapse ― depending on how much earthquake load that is being loaded on the structure. Therefore, it is essential to conduct a structural analysis on the earthquake resistance level of the Rawabuaya flyover bridge based on the "Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung dan Non-Gedung" RSNI 03-1726-2010 and "Peta Zonasi Gempa Indonesia 2010" to know further about the on-going deformation. This research was done thoroughly by recognizing the maximum forces in the combination of ultimate loads based on the most recent rules of encumbering, including the rules regarding the seismic load. The maximum forces in the combination of ultimate loads were compared with the forces' nominal values, especially those related to the seismic load. From the research, it was concluded that the values of the maximum forces in the combination of ultimate loads had the combined seismic load worked on the upper structure of box girder as well as on the structure beneath the pier of Rawabuaya flyover bridge with a maximum moment values of 800300.80 KNm applied to Pier P6B with the combination of the singular ultimate load, additional dead load, pre-stressed load, and “T” truck load. Impairment to the structure was found to happen if the combination of the ultimate load was forced to work continuously on the Rawabuaya flyover bridge. Meanwhile, the result of the compared maximum forces in the combination of ultimate load with the values of nominal forces indicated that the Rawabuaya flyover bridge had a large amount of seismic load with 10% difference. It meant that this structure was able to resist 90% of ultimate seismic load, which required the usage of reinforcements on the upper structure of box girder as well as on the structure beneath the pier to increase the concrete stress power and the tendon on the upper structure of box girder to increase the tensile of the concrete. Keywords: prestressed box girder, structural analysis, seismic load, force]]>

<![CDATA[Bogor Agricultural University (IPB) Campus is an urban area that experienced flooding when heavy rain occurred, especially at Graha Widya Wisuda (GWW)’s parking lot, Kamper Street (FEMA), Meranti Street, and Tanjung Street. The drainage system of IPB campus is a conventional system. It drain surface runoff as fast as possible to the outlet. Zero Runoff System (ZROS) is one of technologies to minimize runoff using water storage. The advantages of ZROS are runoff minimization, local aquifer’s recharge, and damage mitigation on public facilities. This research aimed to design ZROS at IPB Campus that capable to minimize surface runoff. This research started by water catchment area (WCA) delineation, design rainfall and peak runoff analysis, infiltration rate measurement, and ZROS design calculation. Based on frequency analysis the design rainfall was 125.68 mm. Sub-sub-WCA 1-1C (3 locations), 1-1B, 2-1B, and 2-2A were the flooding’s location. Water pocket is the proposed technology to be applied in ZROS. To mitigate flooding, sub-sub-WCA 1-1B, 1-1C, 2-1B, and 2-2A needed 44 units of water pockets with length of 1.20 m (sub-sub-DTA 1-1B, 2-1B, dan 2-2A) and 1.60 m (sub-sub-DTA 1-1C), with depth ranged from 2.41 m to 3.40 m. Keywords: drainage, flood, runoff, water balance, ZROS]]>

<![CDATA[Naturally in a watershed rainfall distributes spatially. To know rainfall in the watershed needs information from many installed rain gauges. However, rainfall data is found not completely recorded. It is then important to estimate missing or unrecorded rainfall data. This study aims to estimate annual rainfall data in stations by using ANN (Artificial Neural Network). This study was conducted in Cisadane watershed. This study perfomed using rainfall data for 14 periods, the location of rainfall post (coordinates and elevation), DEM map, and watershed map. Data processing and analyzing performed using Ms. Excel 2010, ArcGIS 10.0, and BackPropogation Neural Network 1.0 program. Data used as input in ANN to estimates unrecorded rainfall data were coordinates (X,Y) and elevation (Z) of each rainfall post. ANN can be used to predict the amount of rainfall in cisadane watershed marked with a value of determination (R2) 0,97. After all data complete, average of rainfall in Cisadane watershed can be calculate using arithmetic, thiessen polygon, and isohyet. The amount of rainfall watershed in Cisadane using the arithmetic mean produce rainfall of 2.609 mm, with Thiessen Polygon of 2.539 mm, and with Isohyets of 2.594 mm.
