<![CDATA[The potential of traffic problems at non-signal intersection relatively higher and more complex than signalized intersection. Intersection of Dramaga-Bubulak street has no signal and is one of the intersection with high level mobility. The research objectives were to analysis the performance of actual conditions and alternatives strategies to improve intersection performance as well as to know the influence of one way traffic system on intersection performance. The results showed that the volume of traffic passing the intersection were 3816 passenger car unit (pcu)/hour at peak hour with degree of saturation (DS) of 0.85 and delay on the intersection was 14.41 sec/pcu so the intersection service level was B. The service level of intersection was good, so the research analyzed three alternatives strategies to decrease DS value. Performance analysis of traffic showed that alternatives I was the best model alternative condition, because application of one way traffic system on outer ring Bubulak would decreased the service level of Dramaga-Bubulak street.Key words: intersection, non-signal, street]]>

<![CDATA[Land use change due to housing construction can indirectly damage the water catchment area. This resulted in a decrease in the area of rainwater absorption that caused rain water collected on existing drainage channels. This study aims to analyse the number and dimensions of infiltration wells in reducing the volume of inundation and determine the value of effectiveness reduction of runoff. The infiltration wells was used to collect rainwater and absorb it into the soil. Based on the calculation in Babakan Village area of 2.42 ha, with runoff coefficient of 0.4 for village character, and design rainfall of 97.36 mm/day, the estimated flood volume based on SNI 03-2453-2002 was 805790.30 liter or 805.79 m3. Based on the calculation, Babakan Village needed 115 infiltration wells and 76 trenches. With the infiltration wells and trenches, the total flood volume can be reduced 620.62 m3 or 77.02% of the total runoff.Keywords: design rainfall, infiltration wells, runoff, trenches ]]>

<![CDATA[Bogor as tourist destination at weekend bear quite high vehicles volume. The purpose of this research was to analyze corelation between vehicles volume at highways gate and NOx exposure from the vehicles. By knowing the average concentration of NOx exposure level pollution risk to the health of highway gate worker could be analyzed. This research using Griess Saltzman method referring to SNI 19-7119.2-2005 using some equipment like impinger. The result showed that type of vehicle that produced the highest amount of NOx pollutant was vehicles with diesel engine, and the gate with highest NOx concentration was gate 08 with NOx concentration value 40.008 µg/m3 at 09.00-10.00. Risk quotient (RQ) to the workers with weighed 65-90 kg and had been working for 25 years was 0.041950 and it was RQ < 1. It meaned that the average pollution caused by NO2 at the highways gate does not affect workers and workers does not cause any health risk because RQ < 1. For the next research, it would be recommended to conduct on O3 and NO3, because those compounds are easily reacted with NOx in the air.]]>

<![CDATA[Cultivated paddy fields that applied in Indonesia currently produces high emissions of greenhouse gases (GHG), particularly methane gas (CH4). This research aimed to analyze CH4 gas emission in various water management, and to develop DNDC model in predicting CH4 gas emission. This research was conducted from January to May 2018, located at field laboratory of Departement of Civil and Environmental Engineering. The research was conducted by three water regimes i.e., continuously flooded (RT) for conventional rice farming, wet regime (RB), and dry regime (RK) for system of rice intensification (SRI). The highest total methane (CH4) flux was 48.74 kg/ha on RT, on RB was 3.59 kg/ha and on RK -5.40 kg/ha. DNDC model needed data inputs of climate, soil physics, vegetation and anthropogenic activities. The result of the DNDC model showed that the highest total CH4 flux was 44.44 kg/ha on RT, on RB was 17.88 kg/ha and on RK was 0.02 kg/ha. The result, of total actual of CH4 gas flux was compared with DNDC model and got the coefficient of determination (R2) values 0.93, so the model could be used to predict total CH4 gas emission.Keywords: DNDC, methane gas, paddy field, water regime.]]>

<![CDATA[One of the causes of the decreasing of water quality was the increasing of inappropriate human activities that caused water pollution. Cihideung River was being made as water resource in the campus area which the water have been used for a lot of activities in IPB Dramaga Campus. The purpose of this research were to analyze the clean water quality from the ground water tank (GWT) in Cihideung to the new buildings of the FEM, to compare the result with a national quality standard, to determine the criteria of clean water quality based on STORET method, and to analyze the influence of time and weather to the water quality. The parameters which had concentration below the standard were TDS, turbidity, temperature, iron, fluoride, chloride, manganese, and sulfate, and biological parameters like the total coliform/E.coli. The parameters which exceeded the standard were the value of color of 60 TCU in Cihideung GWT at rainy afternoon and pH of 6.38 in wing 1 sanitary at rainy morning. According to the US-EPA system, the water quality of distribution channels of FEM new building were classified into grade B, that meant light contaminated.Key words: distribution channels, quality standard, water pollution, water quality]]>

<![CDATA[Groundwater needs will increase in accordance to area development. Groundwater has a limited quantity because it depends on the geometry and distribution of aquifer. The purpose of this study were to identify soil lithology and aquifer thickness, to determine soil hydraulic conductivity values and to predict potential groundwater reserves in Dramaga District . The processed data were data geoelectric with Schlumberger configuration, hydrogeological maps, and geological maps of Bogor. Aquifer thickness were obtained from the average yield of the aquifer thickness at the research location. Thickness of unconfined aquifer was 14,69 m and 17,77 m for confined aquifer. Aquifer had lithological layers of andesite, tuffaceous, sandstone, clay, and sand. The value of hydraulic conductivity was 2,5 m / day for unconfined aquifer and 2,04 m / day for confined aquifer. Using the Darcy equation groundwater reserves were estimated 241,29 m3 / day or 2,79 l / s for unconfined aquifers and 1291,19 m3 / day or 14,94 l / s for confined aquifers.Key words: aquifer, Darcy equation, geoelectric, groundwater reserves]]>

<![CDATA[Indonesia is an archipelago with a high risk of earthquakes. Traditional houses in Indonesia are very varied, distinctive, and made of wood. Rumah gadang is one of the traditional houses and located in Minangkabau, West Sumatra. Rumah gadang in various regions are threatened due to natural disasters. The purpose of this research were design and analyze rumah gadang structures againts the durability on earthquake. The analysis used software SAP2000 v14 and Microsoft Excel. The main material was pheasant wood or senna siamea with density 800 kg/m3 and the modulus of elasticity 11000 MPa. Based on the calculation of maximum internal force, the combination of load and resistance factor design (LRFD) was greater than the combination of allowable stress design (ASD). The actual pressure was smaller than the ultimate pressure so structure was fulfill the strength standard. Buckling didn't occur when the ultimate pressure work. Maximum flex occur on the roof was 1.08 cm due to the hight of roof cross-section is smaller than the width off cross-section. Keywords: ASD, earthquake, LRFD, rumah gadang]]>
