Abstract

Ibis Hotel and Candi Land Apartment located at Diponegoro street currently are built into the new residential alternative in Semarang. This will trigger trip generation in the future, thus will increase congestion in the area. Therefore, it is important to assess the impact of the hotel and apartement operations. This study aims to predict the trip generation, evaluate the performance of the existing road network, predict the performance of the network after the operation of Ibis Hotel and Candi Land Apartment and propose the solutions to encounter the conditions. Analyses of the performance of segments, signalized intersection and roundabout refer to IHCM 1997. Trip generation prediction of hotel and apartment refer to Department of Transportation regulation. Based on the analysis, Ibis Hotel and Candi Land Apartment trip generation amounted to 341 pcu/hour. The existing degree of saturation (DS) of the nearest road segments are 1.40 on Sriwijaya street, 1.64 on Diponegoro street, 1.00 on Veteran street, 0.57 on Pahlawan street, 0.85 on Kawi street, 0.84 on Sultan Agung street, and 1.55 on S. Parman street. The degree of saturation of Pahlawan intersection is 1.92 (North). Thus, the degree of saturation of Diponegoro Park roundabout is 1,00 (CD inweave Diponegoro street – Kawi street). After the operation of Ibis Hotel and Candi Land Apartment, the degree of saturation of Pahlawan intersection will increase up to 6,97%. The Degree os saturation of Diponegoro Park roundabout will also increase for about 5,12%. The proposed solution on Pahlawan intersection are to make Veteran street a one way road leaving the intersection and reset the green time. This treatment will decrease the degree of saturation up to 21 – 32 %. The proposed solution on the nearest road segments are to widen the road segments that cause a decrease on the degree of saturation for about 17-31%. Whilst, the proposed solution for Diponegoro Roundabout is to give road signs which are expected to reduce conflict on the weaving area.

Abstract

Construction project have problems regarding waste, which can be in forms of Physical Construction Waste and Non-Value Adding Activity. The purpose of this research is to evaluate waste that occured in construction projects, while the aim of this research is to know the frequency and impact of waste, as well as the waste cause factor. The object of the research was waste on building project in the area of Semarang. Waste identification was carried outfrom literature, observation and interview and wereanalyzed using fishbone diagram to get waste cause factor variable. Waste variables were divided into four categories, i.e. waiting periods, material, human resources, and operations. Waste cause factor variables were grouped into six categories, i.e. people, professional management, design and documentation, materials, execution and external.Questionnaires were distributed to 100 respondents of 12 different contractors, with response rate of 65%. Data was processed by Weighted Mean Score (WMS) method. The results of this research showed that “extra work” waste had the highest frequency, “rework and repair” waste had the highest impact, and “slow drawing revision and distribution” and “design changes”, were the highest waste cause factors on building projects in the area of Semarang. The results of data processing also showed that structural works was type of work where waste often occurred. The result of risk-waste matrix showed that “extra work” was included into high risk-waste category which means it could cause serious disruptions to the project execution and company’s finance.

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.
