Land conversion happens on the open land into developed regions an impact on the improvement of storm water runoff and impairment infiltration or water storage amount that goes into the ground. Eco drainage is drainage infrastructure of urban areas where rainfall runoff is not directly channeled water receiver but accommodated in the retention pond to provide sufficient time for the water to seep into the ground. Retention pond is designed not only as flood control but also as a place of recreation for the park to be combined with increasing the area of green open space and improve the esthetic value of theenvironment. The completion of this study using EPA SWMM 5.0 assistance program to analyze the suitability of the drainage capacities to cope with the flood problem. The results showed that the problem of flooding due to the capacity of the existing channel with a dimension of 1x1 m not in accordance with the conditions of rain and runoff into drainage capacities with a value of 1.0 or 100% has been filled with runoff that goes into the drainage. Simulation repairs done by using the channel dimensions 2x2 m still not able to cope with the recent flooding. The capacity of the existing line with the percentage Impervius undeveloped land with a value of 85%, 60% and 2% can be maximized by the addition of the retention pond with an area of 2 hectares and a depth of 2 m as well as changes in the dimensions of the channel just upstream (3x3m) and downstream (2x2m) into alternative solutions to problems ofurban flooding in the region. The capacity of drainage channels and retention ponds planned until the 20 years in the future development of the city of pekanbaru RTRW according to changes in the percentages of land be impervius 95% still holds a runoff into drainage channels so that the problem of flooding in the area of AKAP Subdistrict payung sekali can be resolvedKeyword : Flooding, Eco drainage, Retention Ponds , EPA SWMM 5,0

Abstract

Times showed population growth of Pekanbaru city with the development of local economic activities rapidly. Regional regulations of Pekanbaru city had been not adhered mainly by local people by building houses in the drainage canal and river border line. It was occurred in Siak river area, the people were living along the bank of the river and became into a densely populated area, seedy and less healthy. Therefore, it is necessary to design a Flats are able to answer the needs of the community in avoiding density, untidiness and maintaining health. Because site is located on the bank, so the design must be able to adapt to nature and local climate and then the design of this Flats using tropical architecture approach according Lippsmeier. Where tropical condition requires special handling in its design, the main effect is from the condition of high temperature and high humidity comfort level such as the level of cool air at home by draft. In realizing the convenience so then in this Flats design uses the concept of Verticl Garden in design. So that, the Flats can be a dwelling or shelter for the residents as well as more well ordered.Key Words : Flats, Tropical Architecture, Vertical Garden.

Abstract

Local scour at bridge pillars that occurs continuously will cause damage to the bridge structure. Many forms of pillar have been developed to minimize local scouring, but yet provide maximum results. Laboratory model has been developed to identify the local scour phenomena on the grouped cylinder pillar by looking at the phenomena with and without pillar protector. The bed of model is using Kampar sand with grain size d35 = 0,285 mm, d50 = 0,330 mm and d65 = 0,380 mm and Gs = 2,63. Three variations of the flow used in this research is classified on the type of subcritical flow with Froude number ranged from 0,46354 – 0,76903. Reynolds number in Fr1 scored 1658,416 then included in the transitional flow and turbulent flow occur in Fr2 scored 3081,683 and Fr3 scored 4381,188. Hjulstorm graphic shows that the granules of gradation used in this research in moving zone. Hydrodynamic flow in pillar causes downflow on the front pillar and wake vortices are formed on the back, so that the presence of these forces will create a horseshoe vortex at the bottom of the pillar. The equilibrium of scour depth against time function occurred at minute 75. The maximum ratio of scour depth (ds/b)  is 2,9 which occurs in Q3P. Pillar protector of curtain type can reduce scour depths  of up to 62,07 %. Sediment transport analysis result prove that the higher Froude number is used the bigger the granules are transported.  Key word  : local scouring, laboratory model, grouped cylinder pillar, hydrodynamic flow, depth ratio.

Abstract

Clays are soft soil which have a low bearing capacity. One of the methods to determine the soil bearing capacity is CBR (California Bearing Ratio). Research on Laboratory for determining CBR value of soil generally performed on condition of optimum moisture content or fully saturated soil. This research evaluates the CBR value of clays with various fly ash contents from OMC to fully saturated. The results showed that, when the soil is compacted at OMC conditions, the effect of saturation resulted will decrease the CBR value up to 67% of CBR unsoaked. When soil is compacted with moisture content above the OMC, increase of water content resulted will decrease the CBR value up to 24%. Furthermore, the addition of fly ash content is effective to improve the CBR value between 20% -25%.  Key Words: CBR, water content, clay, fly ash
