Abstract

Significant shift in the land use within Siak watershed (DAS Siak) affects to groundwater reserves. This also affected to fluctuation of the river flows. Therefore to develop a comprehensive watershed management strategies, it is required a hydrological model which is in capable to represent the hydrological cycle of the watershed. Hydrological model may use SWAT application software package. The SWAT simulations performed various scenarios for land use changes in the period of 2002, 2007, and 2012. Based on this research study, the optimal determination coefficient (R2) of SWAT output models were = 0.59, with Nash Suflicfe Efficiency (NSE) was 0.58. The determination coefficient for validation models was 0.55 and NSE was 0.48. These results have satisfied the reserach objectives as the findings coefficient were > R2 min 0.4, and >NSE 0.35. The level of ground water reserves was calculated by comparing the ratio of Qmaximum and Qminimum during the period of 2002 to 2012. It was revealed that the ratio of ground water reserves were as the following order 10,725 (2002), 6,834 (2007) and 12,951 (2012) respectively. Should the ratio value Qmaxsimum / Qminimum was bigger, the more critical ground water reserved will be. Hence, the fundamental changes in land use is Siak watershed affected to suppress the ground wateer reserve to the critical level.Keywords: Land use change, SWAT model, ground water reserve.

Abstract

The decrease of road verformance is due to various factors such as the activities on the side of the road. These activities include side barriers, such as in and out vehicles, stopping vehicles, roadside parking, and pedestrians. Soekarno-Hatta Road in front of Transmart mall is currently experiencing a performance decreased during peak hours due to the increasing volume of traffic flow caused by the activity of the vehicles that going in and out fromTransmart mall. The purpose of this study is to analyze the traffic performance on the Soekarno-Hatta road in front of the Transmart Mall and find solutions to solve the problemthere. Road performance calculation method in this study was referenced to Indonesian Road Capacity Manual (MKJI 1997). The traffic data wer calculated over four days. Based on theanalysis of existing conditions at the highest peak hours occurred on Saturday at 16:15 to 17:15 pm with the result Q = 2553 pcu/hour, C = 3234 pcu/hour and DS = 0,79. Therequirement of DS < 0,75 (MKJI 1997), while the existing DS is 0,79, exceeds the MKJI requirement, so it needs a certain traffic arrangement to improve the performance of the road.One of the alternative improvement is widening the road by 5 m, from the initial width of 7 m to 12 m, This widening decreases DS value to 0,5 which is fulfill DS requirement (DS <0,75).Keywords: Soekarno-Hatta Road, Road Performance, Side Barriers, MKJI 1997

Abstract

Peat is organic soil, but that does not mean organic soil is peat soil. Peatlands in Indonesia are 14.9 million hectares, covering around 50% of the world's tropical peat. Riau Province which has the largest area of peatlands in Indonesia is 55.3%. Unproductive peatlands in Indonesia are reported to be 4.2 million hectares. Under natural conditions, peat is a type of water-saturated soil that can store water up to 5 to 15 times its weight. This research was conducted in the village of Tanjung Leban using peat soil water content of each layer. Results Peat soil moisture content is used to determine the parameters of the Fire Danger Rating System (FDRS) water content. The analysis was conducted using primary data in the form of soil sampling and laboratory testing of soil mechanics. The results of this analysis obtained the value of the average water content of each layer. The average value of layer moisture content is different from the first layer of litter moisture content of 65.39%, the value of moisture content of the second layer of organic soil is 71.22% and the value of moisture content of the third layer of solid soil is 71.04%.Keywords: peat land, Fire Danger Rating System, water content

Abstract

The non-functioned traffic lights at intersection point of Jl. HR. Soebrantas-Jl. Kubang Raya-Jl. Garuda Sakti, Pekanbaru, is the main factor that lead to an increase in degree of saturation to 0,962. The value of degree of saturation is greater than the requirement of Indonesian Highway Capacity Manual (IHCM, 1997) which is 0,85. The IHCM method was used to overcome the congestion problem at this intersection point by specifying 4 alternatives solution. There was an increase in DS value by 8,64% for initial condition in alternative 1, a decrease in DS value by 4,78% from alternative 2, a drecrease in DS value by 2,09% for alternative 3 and a decrease by 20,26% in alternative 4. Hence, from the result shown, it is believed that alternative 4 is the best alternative to overcome the congestion problem at this particular intersection point.Keywords: intersection of Jl. HR. Soebrantas-Jl. Kubang Raya-Jl. Garuda Sakti, DS (Degree of saturation), traffic flow.
