Abstract

The construction development which grows fast in Indonesia is causing needs of supporting technology that give more efficiency yet it also has to be more effective. Technological developments in the field of construction is giving a system called Building Information Modelling (BIM) as a result. Before BIM, we already aware of AutoCAD, SAP, Ms.Project that have been used for project planning, the use of these softwares take a lot of time because they can’t be integrated, so it need more cost, human resources and time to for a project planning. BIM encourage the exchange between different diciplines, so that this exchange process could get faster and affecting the costruction itself in a good way. Currently in Indonesia, there are a lot of construction workers who haven’t use BIM technology, even acknowledge about the benefits it gave, while in fact, BIM have so many excellences compared to the common technology that have been used. Thus, writers do this research to acknowledge about comparison between BIM and conventional methods. Writers are using three methods, they are questionnaires, interviews and a case study, to acknowledge about the performance of BIM. With case studies planning of 20 storey building made comparisons between the efficiency of conventional methods with BIM concept in need of time, human resources and costs for project planning.This study concluded that the use of the application with the concept of BIM can accelerate project planning time by ± 50%, BIM reduces the human resources needs by 26,66%, and saving personnel costs to 52,25% as compared to using conventional 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.

Abstract

Gayamsari District Area of Semarang is one of the flooded area. The causes of flooding is local rainfall that occurred in the village Gayamsari, Pandean Lamper, Siwalan and Sambirejo which is a sub-system of the East Flood Canal, where the channel capacity in the area can not accommodate the flow of water passing through the channel. Limited drainage capacity caused by the blockage of garbage and sediment that makes the water can not flow when it rains. This causes the drainage channel over capacity when it rains with great intensity and in a rather long time, which can result in a puddle with a depth of between 20-50 cm for ± 1-5 hours. To overcome this done drainage planning in order to cope with floods and inundation in the area. The initial steps of planning a drainage cover primary and secondary data collection, planning drainage used 14 years of rainfall data, topographic maps and the existing drainage system. In planning, hydrological analysis to seek the discharge plan with EPA SWMM program. Obtained flood discharge plan with a return period of 5 years on each subcatchment ranged from 0.24 to 3.81 m3 / sec. Furthermore, to determine the effectiveness of the existing channel cross section is modeled with HEC-RAS program. Planned cross-section with a steady flow conditions. The results of calculations using the program shows a cross section in the downstream Gajah Raya Street and Soekarno-Hatta Street can not accommodate discharge plan. Handling is done by increasing capacity of the drainage channel and making the detention basin.

Abstract

Reduced green open areas and forests in upstream of Beringin watershed areas is affect the run-off, so it is possible resulting in increased surface run-off, decreased time of concentration, and at the same time a decrease in groundwater recharge. Thus the flow in the rainy season will tend to rise and discharge will decrease in the dry season. Comparison of river's Qmax (usually in the rainy season) and Qmin (in the dry season) is very large. The greater the ratio of river's Qmax to Qmin, indicating the further degradation of the watershed. Upstream areas in the South is quite hilly with steep slopes, with a height of 12.5 m to 250 m. The issue of Beringin River originated from land use change in the uplands, especially on open land (forest, shrubs, and farm or agricultural) into housing and settlement, causing flooding in the watershed  Beringin. To calculate the average maximum rainfall-average using Thiessen polygon method with three rainfall stations that affect which is the Mijen, Tugu, and Mangkang Waduk. Rainfall data were used from 2003 till 2012, while the flood discharge plans taken from the calculation method of HSS Gama I  with a return period of 10 years at 180.59 m3/s. Normalization is planned in the main river along the 7.18 km, from the estuary (STA 0) to the arround Mangkang regency (STA 23). Varying the width of the river is 14 m of STA 0 to STA 8, 12 m of STA 9 to STA 19, and 10 m of STA 20 to STA 23 with the same slope at 1: 1.5. This cross section plan has previously been simulated with HEC-RAS 3.1.3 program and the results was they were able to accommodate discharge plan that occurs. Safety height of 0.6 m was added in each cross section above the water level of the river. Revetments also added to the bend of the river in STA 22-23 with a length of 200 m and a height of 4m. This project implementation is scheduled for 28 weeks with a budget plan of of Rp 16,881,359,000.00.
