Abstract

The traffic problems in a big city such as Semarang generally caused by the typical situation like overcrowding at peak hours. To overcome this problem, Semarang Government has implemented “One Way System” on the Indraprasta Street section without providing road partner. This study is intended to identify the effectiveness of this policy. The following streets were reviewed: Indraprasta, Imam Bonjol, Mgr. Soegiyopranoto, and Pierre Tendean. Further, the intersections which studied are Indraprasta-Imam Bonjol-Pierre Tendean and Tugu Muda. Traffic survey data were collected in the morning and afternoon peak hours. Manual Kapasitas Jalan Indonesia 1997 was used in the data analysis procedure. This short-term study was conducted by simulating the proposed scenario and compared with the existing situations.In conclusion, “One Way System” on Indraprasta Street section is assessed not effective due to its relatively small degree of saturation, while Mgr. Soegiyopranoto Street has a large degree of saturation. Therefore, the one-way system to Imam Bonjol Street and Mgr. Soegiyopranoto Street also needed to implement and form a “rotary link“. In addition, enacting contraflow for public transport on Soegiyopranoto Street and Imam Bonjol Street is necessary, also the arrangement of signals and geometric in the intersection that linked those three streets.

Abstract

Inundation of flood and rob (flood due to high tides) in Semarang City is increase wtithin area and depth. It be more seroius condition because of land subsisdence that happened in coastal area of Semarang City. This research is foccused on prediction and mapping of inundation flood and rob due to land subsidence effect in East Semarang, especially Tenggang Watershed and Sringin Watershed. On this research, data analysis including analysis of land subsidence, analysis of hydrological data, analysis of flood discharge with HEC-HMS, hydraulics analysis with HEC-RAS and then mapping the results of the flood inundation with Arc GIS. The inundation will be create with overlay the DEM of flood water level and DEM of topographic. According to the results of analysis is known that minimum land subsidence is 0 cm/year that happened in south area of Semarang and more higher ini north area with maximum land subsidence is 5.58 cm/year. On periode   2014-2031, the contribute of land subsidence to increase the inundation of flood and rob is 1.39%/year.

Abstract

National road are crucial to the economy and it spurs the economic development potential of the area contained in the province of Bangka Belitung Archipelago. National road lines is the busiest traffic lane linking inter-cities/regencies in Bangka Island requires maximum handling but the ability of the central government in providing funding is very limited. Prioritization of road handling must be done evenly as needed so that the purpose of the existence of these roads remains unfulfilled. The purpose of this study was to determine the priority handling of national road Lines in Bangka Island by the method of Analytical Hierarchy Process (AHP) using 6 (six) criteria. Data results of the questionnaire showed that of 6 (six) criteria taken in this study namely accessibility (19.3%) is the most dominant criteria. Followed mobility (17.6%), the condition of roads (17.1%), current road segment (16.3%), the development of regional (15.9%), and Economic of Gross Regional Domestic Product (13.8%). By entering the 6 (six) criteria to 21 segments, the roads segment that became the priority of road handling is Sungailiat – Boundary of Pangkalpinang  followed Tanjung Gudang - Lumut, and the next successive.

Abstract

An expansive clay soil material that is composed of various minerals include kaolinite, montmorillonite and illite group. Mineral montmorilinite have the sensitivity to the effects of the water is very easy to expand and contract. High and low levels of development (swelling) and shrinkage (shrinkage) expansive clay is determined by the high and low content of montmorillonite on expansive clay granules. Because of these properties are very high content of montmorillonite often cause problems in the building. This study uses a solution of sulfuric acid (H2SO4) as a stabilizer through the compaction process Modified Proctor on OMC Proctor standard by the number of collisions each is 10 x, 25 x and 56 x, and the amount of additional water in cc on dry ground, with variations in increments of 100%, water by 90%:10% H2SO4, water by 80%: 20% H2SO4 and water by 90%: 30% H2SO4. This research was conducted testing-testing in the laboratory include: physical properties, mechanical properties. swelling pressure, swelling potential and CBR with curing and no curing. Results of the test-the test, can increase the value of physical and mechanical properties, while pergujian against swelling pressure and swelling potential is not significantly increased.

Abstract

The flood disaster is one of the natural phenomena that are difficult to avoid. The risk of flood losses that occur in urban areas is generally greater than that occur in the countryside, which it is more due to the differences in the level of public welfare facilities and population density factors The increase in population and the high cost of residential land in urban areas, the greater the pressure of land use for settlement penetrated even in areas that have the potential to floodwaters. To avoid big losses due to flooding and loss of life, it is necessary to disaster management which includes the establishment of alternative evacuation routes, the storage location of refugee. This study will analyze and choose the path of evacuation of the population that are effective and safe as a result of flood-based Geographic Information System (GIS). Stages study began with an analysis of the magnitude of flooding, inundation extents, data collection and analysis of population, density and location of concentrations of residential quarters, global topography and the existing road network system. The study used a case in West Semarang Regency, with a fairly dense population and prone to flooding. Results of this study are expected to be applied to the area of research and can be used as a model for the evacuation of residents due to floods elsewhere.

Abstract

One dimensional flow is often used as a flood simulation for the planning capacity of the river. Flood is a type of unsteady non-uniform flow, that can be simulated using HEC-RAS. HEC-RAS software is often used for flood modeling with a one-dimensional flow method. Unsteady flow modeling results in HEC-RAS sometimes refer to error and warning due to unstable analysis program. The stability program among others influenced bend in the river flow, the steep slope of the river bottom, and changes in cross-section shape. Because the flood handling required maximum discharge and maximum flood water level, then a steady flow is often used as an alternative to simulate the flood flow. This study aimed to determine the advantages and disadvantages of modeling unsteady non-uniform and steady non-uniform flow. The research location in the Kanal Banjir Barat, in the Semarang City. Hydraulics modeling uses HEC-RAS 4.1 and for discharge the plan is obtained from the HEC-HMS 3.5. Results of the comparison modeling hydraulics the modeling of steady non-uniform flow has a tendency water level is higher and modeling of unsteady non-uniform flow takes longer to analyze. Results of the comparison the average flood water level maximun is less than 15%  (± 0,3 meters), that is 0.27 meters (13.16%) for Q50, 0.25 meters (11.56%) for Q100, dan 0.16 meters (4.73%) for Q200. So the modeling steady non-uniform flow can still be used as a companion version the modeling unsteady non-uniform flow.
