In order to make good decisions in transportation, decision-makers need some references to support it. One of the sources for such reference is by performing a micro-simulation; a model for representing real-world conditions including the behavior of travelers, vehicles and the infrastructure. This study examines and presents a comparison between AIMSUN (a commercial micro-simulation software) and Indonesia Highway Capacity Manual 1997(IHCM-1997) in relation to the road traffic performance of the study object Södralänken, E266 and E75, in the southern part of Stockholm, Sweden. A calibration process was conducted in order to find the best value of a set of parameters in each software, selected based on the lowest value of a Root Mean Square Error (RMSE) computed based on observed speed data and the model output. The parameters were then validated using evening peak-hour data. The comparisons were conducted in terms of flow, speed and density by AIMSUN, IHCM-1997 and the observation data on morning and evening peak-hour. The results are from the given experiments with the AIMSUN software with the best set of parameters being when the value of Maximum Desired Speed is at 100 km/h and Speed Acceptance is at 1,1. It shows that the significant difference between AIMSUN, IHCM-1997 and observation lays on the speed. IHCM-1997 gives relatively higher speed than both AIMSUN and observation data.

Mt. Merapi’s eruption which occurred on 26 October 2010 had disadvantageous impact for human life that live surrounds it. The primary disaster was pyroclastic cloud that destroyed villages surround it. In addition, the secondary disaster continuously became a threat for human life around the rivers that destroyed at Mount Merapi. One of the secondary disasters is Putih River’s volcanic material overflowing into Yogyakarta-Magelang Highway. The series of Sabo dam which had been built along the river could not handle that phenomenon. Sabo dam was built and expected to accommodate volcanic material or at least to resist the velocity of volcanic material (sediment controlling), so the damage caused by the flow became relatively small. However, this function could not work at that phenomenon. In order to know the function of sediment control of Sabo dam in Putih River, it is necessary to study the performance of Sabo dam. This research used Kanako software ver. 2.04 and reviewed Sabo dam PU-D1 Mranggen and PU-C8 Ngaglik. There were four simulated scenarios in this research: a scenario without Sabo dam; with Sabo dam PU-D1 Mranggen; with Sabo dam PU-C8 Ngaglik, and the last with two of Sabo dams. The simulation was based on 23 January 2011 event and simulated for 18.000 s. From this research, it can be concluded that Sabo dam PU-D1 Mranggen can reduce the total volume passing through about 43,998.6 m3 or 1.53 % for 5 hours, and reduce the sediment volume that passing through about 28,482 m3 or 52.59 % for 5 hours. Sabo dam PU-C8 Ngaglik can reduce the total volume that passing through about 255.6 m3 or 0.01 % for 5 hours, and reduce the sediment volume that passing through about 124.8 m3 or 0.33 % for 5 hours, and Sabo dam PU-D1 Mranggen and PU-C8 Ngaglik in series can reduce the total volume that passing through about 2,340.6 m3 or 0.08 % for 5 hours, and reduce the sediment volume that passing through about 157.8 m3 or 0.41 % for 5 hours

Every human being has equal right for accessing to the transportation. Difable persons that have different ability also have the same right. The provision of the accessibility and information facility in public transport is not fully meet difable need and therefore difable persons have difficulties in accessibility and information while using public transports. This research will investigate the difable perceptions about accessibility and traveler information for the public transport in Jakarta. Questionnaire method will be used for this purpose and then analyzed by Importance Performance Analysis. The improvement for the transport infrastructure and information system will be elaborated. The findings of the research could be used as input for the local authority while planning or re-construction public transport infrastructure and information system so that difable persons become more accessible and convenience. The study results show that the average value of the perceived performance for the accessibility is 2.78 from 5 scales. This means the performance of the accessibility in overall is fairly. For the information facility, the average performance is 3.11 that meaning the performance in overall is good. The respondents required the provision of waiting room for difable persons as a priority. The information about the departure of the vehicle should been improved as priority to be increased. Furthermore, it is obtained that the Customer Satisfaction Index (CSI) value for accessibility is 56%. This indicates the entire respondents satisfied sufficiently with the accessibility facility. Also, 62% of the CSI value shows that the respondents satisfied sufficiently with the provided information.

DEBRIS FLOW DISASTER MITIGATION THROUGH COMMUNITY-BASED INTEGRATED SEDIMENT MANAGEMENT (BEST PRACTICE IN MT. MERAPI AREA, INDONESIA) Kazuhiko Otani; Suharyanto Suharyanto

Publisher : Department of Civil and Environmental Engineering, Faculty of Engineering, UGM

Mt. Merapi is one of many active volcanoes in Indonesia which erupts frequently. The small eruption occurred nearly every year, whereas the big ones occurred at approximately once every five years. The eruption often produces impacts at both positive and negative view points, such as production of sediment as construction material and damage on infrastructures due to debris flow occurrences respectively. The eruption produces two types of disasters, i.e. primary disaster (such as ash fall, pyroclastic flow, and lava flow), and secondary disaster such as debris flow. This paper presents the long term effort on the development of community participation in the sand mining management as one of strategic disaster mitigation activities. The raising awareness of the community on the necessity of conducting proper sand mining management and its effect on reducing the risk due to debris flow disaster has shown the effectives of the approach being introduced. The local government acceptance on the presence of the community participation in the whole system of sediment management may involve further collaboration between the local government authority and community society in the future.

Rainfall has temporal and spatial characteristics with certain pattern which are affected by topographic variations and climatology of an area. The intensity of extreme rainfall is one of important characteristics related to the trigger factors for debris flow. This research will discuss the result of analysis on short duration rainfall data in the south and west slope of Mt. Merapi. Measured hourly rainfall data in 14 rainfall stations for the last 27 years were used as analysis input. The rainfall intensity-duration-frequency relationship (IDF) was derived using empirical formula of Sherman, Kimijima, Haspers, and Mononobe method. The analysis on the characteristics of extreme rainfall intensity was performed by conducting spatial interpolation using Inverse Distance Weighted (IDW) method. Result of analysis shows that IDF of rainfall in the research area fits to Sherman’s formula. Besides, the spatial distribution pattern of maximum rainfall intensity was assessed on the basis of area rainfall. Furthermore, the difference on the result of spatial map for one hour extreme rainfall based on isolated event and non-isolated event method can be evaluated. The result of this preliminary research is expected to be inputs in the establishment of debris flow early warning in Mt. Merapi slope area.

THE BOGOR BUS STATION RELOCATION IMPACT ANALYSIS TO THE BOGOR OUTER RING ROAD (BORR) AND PANGERAN SOGIRI STREET PERFORMANCE Tri Sudibyo; Imam Muthohar

As the main bus station in Bogor, West Java, Baranangsiang bus station is currently located in the crowded city centre, near many offices, campuses and department stores. There is a plan of Bogor’s Dinas Perhubungan Komunikasi dan Informasi (Diskominfo) to relocate the bus station to the new location in the Pangeran Sogiri Street in Tanah Baru area, near the newly built toll road, the Bogor Outer Ring Road (BORR).This research is conducted to analyze the traffic performance impact of the relocation plan of the bus station to the BORR network and the Pangeran Sogiri Street. The traffic data is obtained from the field survey in the Baranangsiang bus station and the BORR network. Some other secondary data are obtained from the Dinas Lalu Lintas and Angkutan Jalan (DLLAJ) Bogor city. Based on the obtained data, a micro simulation model is built by using Aimsun traffic micro simulation program. The analysis is conducted in three traffic performance parameters; the traffic density, speed, and vehicles queue length. With respect to the analysis result, the relocation causes a serious traffic problem to the BORR network and the P. Sogiri Street. To minimize the problem caused by the relocation, three scenarios are proposed and thus simulated based on the findings and observed traffic problems. The first proposed scenario is conducted by widening the P. Sogiri Street and providing a 4-4 toll payment gate system to the BORR. This first scenario is able to reduce traffic problem in some sections, but the average network density, speed and queue length are still high by 132%, -54%, and 200% respectively compared to the existing condition. The second scenario is conducted by widening the P. Sogiri Street and providing a 5-3 toll gate system. This second scenario is also able to reduce traffic problem in most sections, but the average network density, speed and queue length are still high by 248%, -70%, and 95% respectively compared to the main bus station before the relocation. The third scenario is conducted by widening the P. Sogiri into 4 lanes, providing a 4-3 toll gate system, and providing a new access from/to P. Sogiri Street to Bogor city direction. The simulation result shows that the third scenario is considered as the best scenario since in this scenario, the density, speed and queue length are relatively similar compared to the existing condition.
