Abstract

The development of green construction with the goal of developing the world of constructions are growing. Production process of making steel reinforcement gives negative impact to the environment, such as air pollution, hazardous chemicals and energy waste. This study examines the effectiveness of using reinforcement stirrups in term of their strength and cost. Vertical stirrups have various connection types, such as hooked stirrups and welding connected stirrups. In this study, 6 beam specimens with 3 stirrups variations were prepared, they are 2 beams with hooked stirrups of 135⁰, 2 beams with stirrups welded at the corner and 2 beams with stirrups welded at the center. Eksperimental results of deep beams without compression reinforcements  show that the maximum load that can be resisted by both the beams with hooked stirrups and corner welded stirrups are comparable. With regard to the cost, replacement of hooked stirrups with corner welded stirrups can save 5-10% of the total steel used for stirrups.

Abstract

Separated Highway Casablanca Package is located at Kuningan, Jakarta. This separated highways is designed using prestressed concrete box girder construction. The erection method is conducted by means of balance cantilever method. The main equipment used in the erection of box girder is launcher gantry. Total length of the separated highways is 1175 m, which is divided into 24 spans. This separated highways has 25 piers. The first step of designing this separated highway is by designing the dimension of the box girder. The next step is analyzing the loads that are predicted to work on the structure, namely load, traffic load, wind load, and earthquake load. Next, structural analysis is carried out to obtain the internal forces and stresses in the structure. The result of the structural analysis is used to calculate loss of prestressing force, needs of tendon, and the reinforcement of box girder. The next step is designing Piers and Foundation. The reinforcement in the piers is 1,33 times of the minimum reinforcement required by analysis. The Foundation uses bore piles and calculated using Broms method.

Abstract

The land degradation of Cimuntur Sub Watershed that happened causing the function of sub watershed is changing as a basin. The indication of erosion and sedimentation was 88,55 ton/ha/yr and sediment yield was 0,91 mm/yr. Therefore it needs study to figure out how big is the erotion and sedimentatiom in Cimuntur Sub Watershed so that can get the solution for the problem which happened in Cimuntur Sub Watershed. Analizing of erotion and sedimentation in Cimuntur Watershed is used Universal Soil Loss Equation (USLE) Method and is helped with ArcGIS software. ArcGIS software is used to overlay datas. The input data which is needed for USLE Method is Rain Erosivity Factor (R), Soil Erodibility Factor (K), Slope Length Factor (LS), Land Use Factor (C), and Practical Conservation Factor (P). The result of data overlay by ArcGIS is erotion happened. From the analizing datas is gotten that erotion at Cimuntur Sub Watershed is 963,747 ton/ha/year and sediment yield is 14,649 ton/ha/year. And then making classification of erotion class. This erotion class is made to be used as the consideration base for defining the alternative solution will be done and determine location of erotion and sedimentation solution. The alternative erotion and sedimentation solution of Cimuntur Watershed is done by doing conservation such as vegetative conservation or mechanical conservation. Vegetative conservation can be done by improving the land use management. After doing vegetative conservation, erotion decreases to 237,415 ton/ha/yr and sediment yield 3,61 ton/ha/yr. Whereas mechanical conservation can be done by building a sediment contoller (check dam). Check dam construction is done at big erosion category that is Cirende River with capacity is 8945,95 m3.

The building are design with Structure Frame System method with configuration structure collapsethe System Bearer Special Moment (SRPMK). The structure frame system methodis are the configuration structure of the building with moment resisting frame consisting of beam and column. The configuration system of the Structural Frame System are consist of reinforced concrete structure. The building was firmly designed with some load combination such as dead load, live load, and earthquake. Design with The System Bearer Special Moment (SRPMK) election expected to be a high story building structure behave ductile therefor this building firm enough to be swayed by the earthquake that happened. This system is planned to use the concept of strong column weak beam, where the vertical elements of the structure (column) should be stronger than the horizontal elements of the structure (beam), to be plastically formed jointsfirst on the beam. The joints meeting of the beam-columnshould also be well designed to avoid collapse first. The analysis of the structure of high story building using SAP2000 v12 software help to design structural building. Software are used for helping to determine the fundamental period of the structure and the forces acting on the structure. In the configuration of the structure collapse the System Bearer Special Moment (SRPMK) fundamental structural period must be limited so that the structure is not very flexible. Results in the forces acting such a axial force, shear, tortion and moment on the structure are used to design the structure of high story building.

Abstract

To perform the necessary analysis of wave propagation subsurface soil data are complete and accurate. Data were obtained directly from the field geotechnical surveys and obtained from laboratory tests on soil samples taken from beneath the surface through bore hole. Dynamic soil properties determined indirectly from the results of static testing in the field, the Standard Penetration Test (SPT) and Cone Penetration Test (CPT). Several researchers have conducted studies and generate empirical correlation between shear wave velocity (vs) with SPT N-values and CPT cone resistance (qc) such as Imai (1977), Imai & Tenouchi (1982), Ohta & Goto (1978), and Sykora & Stokoe (1983). Using data from the soil investigation reports of 85 locations spread across the Semarang city, consisting of 156 boring point, 83 point manual CPT, and 96 points machine CPT. To determine the site class parameters using weighted average method of N and vs value for 30 meters topsoil profile. The results of this study become soil properties map ( QUOTE   and  QUOTE  ), and site-class map of Semarang city. Based on two (2) soil properties, soil classification in Semarang divided into two site-class, stiff soil (SD) and soft soil (SE). SE site-class commonly found in the north coast side of Semarang city, while soil SD site-class found in the south side of Semarang city.

Abstract

Siliwangi road is one soars and populous Primary Arterial Road in the Semarang City, so often there is congestion on the roads. Result of frequent congestion on the roads, air pollution which occurs also higher. This study aims to determine how high the air pollution that occur and to provide recommendations for alternative solutions to tackle congestion at the intersection whole observatories, so as to minimize the air pollution that occurs. Traffic survey at the intersection whole observatories done during the morning Peak hour, afternoon Peak hour and evening Peak hours. Survey results are then processed by the Manual Kapasitas Jalan Indonesia (MKJI) 1997 Synchro SimTraffic Program 7.0. Initially, the green time adapted to the needs of the existing condition, then the following adjustments were made in the form of changes in the geometric intersection to accommodate existing traffic conditions. Adjustment of the traffic conditions and the geometric path then known how much pollution that occurred at the intersection. At the intersection of the existing conditions in whole observatories already reached saturation performance , with the calculation of the degree of saturation of the synchro program 7 that almost all of them are above the 1.00 figure. With the adjustment Optimization green time to Simpang whole observatories provide DS to decrease Morning Peak condition that is equal to 5.82%, 5.82% Peak Afternoon, Evening Peak 9.89% and the change in geometric intersection (lane additions of 3.7 m) on condition Morning Peak, Peak Afternoon, Evening Peak resulting decrease in DS respectively 23.80%, 8.95%, and 14.58%. Although not all perform well and there are still some poor performers approach (indicators of poor performance where the value of the degree of saturation exceeds the ideal value of the degree of saturation (DS>0.75). Use of Public Transport assuming 50% removal of the car was replaced with highly efficient use of BRT in reducing the number of DS on condition Morning Peak , Peak Lunch, Afternoon Peak resulting decrease in DS respectively 60.84%, 47.01%, and 61.97%. The scenario design is done well enough for the level of handling performance in the short term. So, it can be concluded that the performance of intersections that were reviewed for the better.

Abstract

This paper will explain how to maintain and improve water quality in Diponegoro reservoir. Krengseng watershed‘s area are Banyumanik sub-district and Tembalang sub-district which is Diponegoro reservoir catchment area that water influent to reservoir should have wastewater quality fit with the quality of wastewater domestic standard. Therefore, it needed domestic wastewater sewerage system and treatment plant in Krengseng watershed area. Domestic wastewater sewerage system and treatment plants design required some data such as quantity of domestic wastewater, water pollutants, population, and also overall site layout that would be used to design the domestic wastewater sewer system. To analyzed and sewer system design, we can used EPA SWMM 5.0 with small bore sewer as the main idea for sewer system. Specification that should be fulfilled are minimum pipe slope more than 0.006, flow rate between 0.6-3 m/s, and water flow quantity in pipe between 0.2-0.8 of pipe diameter. For treatment plants used septic tank as primary treatment and anaerobic filter as secondary treatment. Total cost for this design are planned Rp 133.819.636.500,00 with construction duration for one year and ten months.

Abstract

Volume growth in road traffic is increasing rapidly, especially in the city of Semarang. This makes the occurrence of congestion in the city of Semarang at peak hours, especially at intersections. The problems at the intersection can be overcome by the use of lights at signalized intersections so there is no conflict and clash, but the use of a signal at the intersection also raises its own problems, such as delays and queues occur, especially if there are a lot of adjacent signalized intersections in the road as well as on the road Dr.Cipto Mangunkusumo Semarang who are familiar with the way Dr.Cipto. This study aims to smooth traffic flow on roads Dr.Cipto coordinated way Kartini intersection and Sidodadi intersection. The data was collected by surveying directly at the two junctions at peak hours in the morning, afternoon, and evening. The data is taken from the volume of vehicles that pass through each intersection, signal timing, vehicle travel speed through two intersections, queue length, and geometric intersection. The survey results are then processed using the guidelines Indonesian Highway Capacity Manual (MKJI) in 1997 to obtain the performance of the existing condition, then performed traffic control and compared the results of its performance in optimal condition and scenario conditions. Best performance at each intersection are then used to create a draft of coordination between the two junctions. Results in the condition of existing intersection analysis showed unsatisfactory performance, at the intersection of Kartini shows the degree of saturation is still high in some approach, a large value of the vehicle stop, and delay simpangnya was still great. In planning the optimal conditions has a better performance than optimal conditions seen from the DS and the average intersection delay is smaller than the existing condition, while the condition of scenario planning produces a worse performance than the optimal conditions, so the recommended optimal conditions for used in coordination signalized intersections Kartini and Sidodadi. To perform coordination between the two signalized intersections, planning done is create two junctions cycle time has the same value, the morning peak hour cycle time changed to 82 seconds, the peak daylight hours to 75 seconds, and afternoon peak hours to 100 seconds. Of the distance between the intersection and the vehicle speed obtained offset value is 36 seconds while the bandwidth at peak hours in the morning for 25 seconds, 22 seconds during peak hours, and the afternoon peak hour by 32 seconds. While the efficiency of the coordination of the two junctions of 30.48% for the morning, 29.33% for the day, and 32% for the afternoon. Estimated at morning peak hour north approach can release 2238 vehicles/hour, the afternoon peak hour of 2160 vehicles/hour, and the afternoon peak hour of 2376 vehicles/hour. Coordination performance was good enough for the level of short-term treatment. Thus, it can be concluded that the performance of intersections to be better in terms of the initial conditions.
