Abstract

SMPN 3 Blitar it will be build on Ciliwung street. It was one of access roads to Blitar City. SMPN 3 Blitar it will be operated in 2019, then has to knowed the impact of development on the performance of traffic around it. This study aims to determine the degree of saturation of existing, operating time, and five years after SMPN 3 Blitar was operated. The analysis of this study is using Indonesian Highway Capacity Manual (IHCM). The Primary data in this study is peak hour traffic volume, intersection geometric conditions, and the cycle time for signalized intersections around the site. While the secondary data in this study is the road network, an Origin Destination (OD), the GDP, and Blitar population. The analysis was started with calculating the flow of traffic at peak hours, the capacity of the intersection, and the degree of saturation. The results of the analysis of the degree of saturation (DS) was indicated that the value of the intersection on the condition of the existing DS (2016), which has a value ≥ 0.750 is the intersection of the Ciliwung-Bendo. While the value of DS at the time of SMPN 3 Blitar operation (2019), which has a value ≥ 0.750 is the intersection of the Ciliwung-Bendo. And the value of DS at five years after SMPN 3 Blitar was operated (2021), which has a value ≥ 0.750 is the intersection of the Ciliwung-Bendo.

Abstract

Surabaya city is generally dominated by clay soil. This type of soil has several problems such as low coefficient of permeability, large settlement, and low bearing capacity. Pile foundation is common foundation type applied in clay soil which bedrock layer is relatively deep enough from ground surface. Moreover, pile foundation also has various shapes of cross section which can be appiled in field. The maximum load applied to foundation should be taken into account in order the maximum load (Qmax) does not exceed the allowable bearing capacity of soil (Qallowable).By comparing the cross sections of pile foundation including circle, square, and hexagon, the behaviour of maximum load applied to foundation (Qmax) is investigated based on the results of CPT (Cone Penetrasi Test) using “Philliponnat” method with variations of diameter are 0,3; 0,4; 0,5m at the test locations of (S1, S2 & S3) in order to obtain Qmax < Qallowable.The result of this study indicates that maximum load (Qmax) at the locations of S1, S2 & S3, sorted from the greatest to smallest, are obtained by the cross section shapes of squre, circle, and hexagon. Thereunto, the persentage of maximum load (% Qmax) to the cross section of square at S1 are 100% for square, 79.84% for circle, and 72.01% for hexagon. In addition, at S2 are 100% for square, 74% for circle, and 70,28% for hexagon. The % Qmax at S3 are 100% for square, 95,19% for circle, and 78,82% for hexagon.

Abstract

The higher growth of vehicles, causing congestion on some roads and may worsen air quality in the city of Surabaya. Surabaya City Government plans to build Mass Transport System as an of efforts to decrease the high growth in the number of private vehicles. It is expected that with mass transportation, carbon monoxide (CO) emissions from transportation sector can decrease and air quality in Surabaya is improving. To know the change of carbon monoxide emission (CO) emission from motor vehicle source due to tram construction plan in Surabaya, it is necessary to do research on the topic. The location of this research is at Jalan Urip Sumoharjo and Jalan Basuki Rahmat.The research methodologi is calculating the amount of CO emissions of the existing condition, in the plan condition when mass transit transport (tram) is not in operation and the plan condition if the trams in operation. CO emission rate calculation is based on an analysis of vehicle speed for each condition.The results show for Urip Sumoharjo Road, estimated CO emission for planned condition if tram operates higher than before before tram operates. Compared with the existing condition, CO emissions at Urip Sumoharjo increased by 20.71% in pre-tram plan conditions, and increased by 36.25% at the time of the plan if the tram operated. As for the Basuki Rahmat Road segment, an approximate amount of CO emissions for the planned conditions if the tram operates lower than at the time before the tram operates. Compared with the existing condition, CO emission levels on Jalan Basuki Rahmat increased by 32.49% under planned conditions before the tram operated, and decreased by 2.98% at the time of the plan if the tram operated. This is thought to be the case because the percentage of private transporters using a tram of 25.43% is not significant compared to the reduction of road capacity for tram lines

Abstract

The method used in this research is the method of the Department of Environment (DOE) which is usually referred to the design of the English manner stipulated in SNI 03-2834-2000 namely "Procedure for Making Plans Mixed Concrete Normal". Making concrete mix Bioconc in this study as many as 36 pieces with aged care 7, 14, 21 and 28 days and testing materials in the form slinder 30 x 15 cm with a variation of normal concrete without mix and concrete with the addition of additives Bioconc ie 20% and 30% of the sheer number of cement. Quality of the concrete is planned fc 30 MPa. The results of the study with normal concrete compressive strength of the resulting 24.94 MPa, using additives Bioconc 20% of the compressive strength of the resulting 24.63 MPa, using a 30% Bioconc compressive strength of 19.94 MPa produced using additives as an additive in mixed concrete gives concrete strength decreased from normal concrete mix. It is advisable to pay attention to several factors such as the mix design especially for the concrete mix additives, Cement Water Factor (FAS), material testing, concrete casting and solidification.

Abstract

Slope stability design charts are commonly used to estimate the factor of safety of slope with simple geometry, isotropic, and homogeneous soil properties. However, most of the design charts proposed by previous researchers are only focus on determination of factor of safety that the appreciation of the probability offailure of the slope cannot be made. The paper by Javankhoshdel and Bathurst (2014) is the first that introduced a series of probabilistic slope stability design charts for cohesive-frictional (c-φ) soils. In this paper, the results of probabilistic slope stability analysis using those design charts are compared and validated with theresults obtained from Monte Carlo simulation using Slide 6.0. At the first stage, 42 slope models withvariation of slope angle(α) and mean friction angle(μφ) are built. Then, probabilistic slope stability analysis is conducted using both methods. Two statistical parameters including R-square (R2 ) and standard error (SE) are used to assess the correlation of the results obtained from both methods. Based on the statistical analysis, the following data are obtained:R 2 of mean factor of safety, probability of failure with COVc=COVφ=0.1, and probability of failure with COVc=0.5, COVφ=0.2are 0.9902; 0.9934; 0.9942, respectively. Moreover, SE of mean factor of safety, probability of failure with COVc=COVφ=0,1, and probability of failurewith COVc=0.5, COVφ=0.2are 0.060; 3.789; 3.112, respectively.The results of statistical analysis indicate that the results of probabilistic slope stability analysis using design chart and Slide 6.0 have strong correlation. It also confirms that the probabilistic slope stability design charts proposed by Javankhoshdel and Bathurst (2014) are valid.

Abstract

This study aims to assess the needs of intercity passenger travel demandbetweenSyamsudin Noor Internationl Airport and districts cities in South Kalimantan Privince. Passenger transport in Syamsudin Noor Airport is currently served by Airport CityTaxi, Intercity Taxi and Motor. In general, transport services from and to the airport is still not satisfactory, so that the necessary alternative modes that can fulfill the Syamsudin Noor Airport user expectations.This study using stste preference method results the intercities passenger transport demand thatis possible to organize from Banjarmasin, Banjarbaru and Martapura ranks highest demand number. Other cities such as Pelaihari, Batulicin, Kotabaru and Amuntai occupies the next position. Whilethe other cities despite the relatively smaller amounts of demand but average is still more than 150 people per day. This study results the tariff forBEP rates in accordance with the closest distance to the farthest distance Rp. 20,000, - to Rp. 135.000, -. While passenger survey results forWTP is Rp. 50,000, - to Rp. 150.000, -. So that commercial rates can be considered in accordance with the public willingness to pay.
