Abstract

Simpang Lima is a CBD of Semarang City that has a high level of activity. Improvements have been made to the faces of the Simpang Lima area and included the provision of facilities for difabled, but not yet many difabled persons accessing the area due to difficult access to and from the area. This research aims to assess the accessibility of difable to public open space in Simpang Lima area by analyzing the application of public facilities, especially for difabled and analyzing alternative solutions in the provision of accessible public facilities based on difabled needs. The Data acquired by distributing questioner to the difabled who are members of the “Komunitas Sahabat Difabel” and the audit of difable facilities in Simpang Lima area based on the provision of facilities. Based on the research conducted, it is known that the accessibility in Simpang Lima Semarang area for difabled is still less accessible with the final value of 1.97 from the scale of 1 to 3. This is due to the incomplete disfigured facilities in the area as well as some facilities already available but not in accordance with the provision of difabled facilities. In addition, in this study also produce the direction of planning the area such us, connecting the guiding block there is disconnected, increasing the number of ram at each height different and on each entrance, the supply of crossing lights, the addition of signage especially for difabled, and the addition of other difabled facilities such as parking areas and toilets specially for difabled persons.

Abstract

Revetment is a strengthening structure on river slopes from erosion. Erosion of river slopes can widen the wet cross section of the river and increasing scouring can endanger the surrounding buildings. The construction of the Demangan Water Gate in Surakarta City (Phase I) is planned at the mouth of the Pepe river downstream. The construction work will result in changes in river morphology, therefore it is necessary to protect the river slopes so that landslides do not occur. Apart from being a river slope protector, the Revetment design can also be a recreation area and an inspection road. The construction to be used is a concrete sheet pile revetment with reinforcement of the piles behind it as an anchor. Between the concrete sheet pile and the concrete pile, it is connected by a beam-slab structure so that it becomes a portal system. River slope stability analysis using GeoStudio2018 R2 software. River slope conditions that may occur are applied in several modeling, including: River slope conditions without Revetment reinforcement, River slope conditions with Revetment reinforcement, Conditions when changes in river water level elevation occur and river slope conditions when erosion occurs. Based on the results of modeling analysis on the original slope when the river water level increase then recedes has the smallest safe number (SF = 1,822). This is because on the back side of the Revetment, the active soil pressure is in a saturated condition, while the front side of the Revetment loses hydrostatic pressure as a counterweight. The highest safety number is in slope modeling with Revetment strengthening when the river water level increase (SF = 3.114), because the hydrostatic pressure on the back and front of the Revetment is balanced. Revetment construction on river slopes increases the safety rate by 30.64% - 43.70%. With the strengthening of the river slopes, it is hoped that it can provide sufficient security from the main function of protecting the river slopes and obtaining additional functions as a recreation area.

Abstract

This study was conducted on soil improvement works development Pelabuhan Indonesia III projects, Teluk Lamong Surabaya. The aim of the study was to obtain the optimization of the acceleration of soil consolidation using preloading with prefabrication vertical drain (PVD) and prefabrication horizontal drain (PHD). The method used in this study is the optimization of value engineering methods, which generally consists of phases: information, creativity, analysis, development and recommendation. The study concluded that the consolidation of the soil with alternative preloading system using  landfill with  gd = 1.91 kg/m3 and using  PVD/PHD brand Geowork type MW- 408/Geowork  type SD 100 X 20 with a distance of 80 cm is a method the most optimal soil improvement. This alternative produces a faster consolidation of 53 days from the scheduled time and cost savings of about Rp 1.77 billion from the planned start-up costs.

Abstract

Brick masonry confined with concrete frame is very common for non engineered or institutional building in developing countries. This typical building often seriously suffer from earthquake hit the region. This study aims to evaluate seismic performance of this type of building by developing fragility functions of the structure. Masonry wall is modelled as diagonal strut within the concrete frame. The masonry constituents and composite properties were determined for the model. The structure was subjected to incremental static lateral loading while pushover analysis was utilized to predict the re-sponse of the structure. As the damage states were defined from the spectral capacity curves, the fragility functions were develop for the structure. Based on this study, the seismic performance of the buildings can be determined rationally based on the resulting capacity curve: the infilled frame structure can resist maximum load of 20,3 × 103 kN and open frame is only able to withstand 15,2 × 103 kN. From the fragility curve, it can be concluded that the probability of the infilled frame to reach a certain damage state is lower than the open frame. The results confirm the beneficial effect of the ma-sonry wall to increase the seismic resistance of the building.

Abstract

Accessibility related to public transport is a means of advancing the economic welfare of the community, creating and increasing economic degrees, as well as a precursor sector of other sectors. Therefore, people with disabilities are also entitled to the same service to the public transportation as an effort to realize similarities, the equality of citizens and the enhancement of the role of disability. This research aims to analyse disability access and the role of the transportation service of Semarang and PT. Trans Semarang on Bus Rapid Transit in Semarang City. This research uses a type of qualitative approach that is implemented through interviews, observations and documentation. The conclusion of this research shows that from the regulatory aspects, the government of Semarang should be appreciated because the government of Semarang has tried to fulfill the rights of the disabled. But from the implementation aspect, there needs to be an improvement because the accessibility of disabled people running optimally can be seen through the condition of public facilities in the city of Semarang. Public facilities in the city of Semarang do not completely ignore the reference accessibility means there are public facilities that have been good enough but many more are not optimal.
