<![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[Global warming occurs due to increased concentrations of GHGs in Earth's atmosphere. CH4 gas is one of the GHG which potentially 21 times greater to result global warming than CO2. Emissions of CH4 in rice fields affected by irrigation pattern and micro environmental factors. This research aimed to identify the relationship of micro-environmental factors to CH4 emissions and analyse its sensitivity level. The sensitivity analysis of CH4 gas in this study was done by rank Spearman’s correlation method. The results showed that the irrigation pattern was positively correlated with CH4 emissions. Total flux of CH4 for the stagnant regime was 26.00 ± 3.41 x 103 mg/m2/season, wet regime was 15.33 ± 4.37 x 103 mg/m2/season, and dry regime was 11.80 ± 6.72 x 103 mg/m2/season. The micro-environment parameters that was soil pH, soil moisture, soil electrical conductivity, and water level are positively correlated with flux of CH4, meanwhile soil temperature and soil redox potential are negatively correlated with flux of CH4. Based on the analysis, the most sensitive micro-environmental parameters for CH4 gas emissions are soil moisture, with an average rs value is 0.51 and an average R2 is 0.28.

<![CDATA[The intensity and duration of rainfall will affect the amount of runoff. A proper drainage design is needed so that runoff from maximum rainfall would not cause a problem such as excess water or flood. The purpose of this research were to analyze the runoff volume in Tasmania Regency, Bogor and get drainage network design in accordance with the runoff that occured. Analysis was carried out using SWMM 5.1 software with designed rainfall was calculated using the Log-Person III method of 147.2 mm. Peak discharge runoff from simulation results were 0.01 - 0.08 m3/s. Based on the simulation there were 20 channels overflowed during maximum runoff and 6 channels were high potentially overflowed so that repairs were also needed. The factors that influenced were the amount of runoff, channels capacity were lower than runoff volume, and the low infiltration value of subcatchment so that only a little water could be infiltrated and the rest of rainfall became runoff.Keywords: drainage channel, rainfall, runoff, SWMM 5.1]]>
