Simple urban residential building must meet the technical requirements set forth in the building and structure law number 28 of 2002. In the city of Bogor, especially in the densely populated village of Kayumanis, there are areas that have the potential of landslides. In that area, there are some houses that have been damaged by the movement of land and landslides that can threaten the safety of its inhabitants. Therefore they need to stay aware about potential collapse of several parts of house structures, and then understand how to evacuate to safer area, outside of the house after the incident was stopped. Based on these conditions, it is necessary to evaluate buildings in accordance with FEMA on the safety level of buildings. The structure and modeling analysis using SAP 2000-V10 and Indonesia Standard. Specification of simple urban residential building using the reinforced concrete material with the quality of concrete (fc') 17 MPa, 15x15 cm column dimension, 15x18 cm beam dimension and 4D12 BJTP main reinforcement, and shear reinforcement D8-20. The results of the analysis of urban residential building structures shown in 3D form, obtained values for column structure elements almost close to failure are marked with orange color, while for the element of the beam structure is declared safe marked with green color. From result of modeling analysis referring to FEMA 356 obtained value C0 = 1.0; C1 = 1.378; C2 = 1.0; C3 = 1.0; Sa = 1.011; and Te = 0.2206, which states the value of the displacement target is 0.02 m which is categorized to be at 'The Life Safety' (LS) performance level. This means that if there is a movement of land, the structure of the house is declared stable and has adequate service capacity and damage non-structural part is still controlled.

Indonesia's infrastructure project, particularly toll road projects provide mobilization services to hundreds of millions of workers, including infrastructure supporting functions such as road utility services, road maintenance, and road landscaping. To successfully bring these functions, the infrastructure authorities have to uphold an armada of heavy duty diesel (HDD) equipment including excavators, bulldozers, motor graders, pavers, and compactors. This HDD equipment consumes diesel fuel and therefore releases large quantities of pollutants, including hydrocarbon (HC) and carbon monoxide (CO). In order to manage this emission effectively, an emissions inventory should be made first. The purpose of this study is to propose an inventory technique of emissions from the equipment fleet for toll road project in Indonesia from a by developing HC and CO emissions inventory which can be used as a management backing tool to minimize the environmental impact of the project. The sample case for this proposed technique is Rembang-Pasuruan Toll Road Project Section II in East Java, Indonesia, which utilizes 9 excavators, 2 bulldozers, 2 compactors, 1 motor grader, and 1 paver. By using emission factors from nonroad engine modeling developed by Environment Protection Agency (EPA), it is obtained that the average emission of HC is approximately 29.13 gr/hr or 233.05 gr/day, and the average emission of CO is about 124.94 gr/hr or equals to 999.52 gr/day.

引用

AIP Conference Proceedings 2020年第1期2227卷

作者： Tri Tjahjono Andyka Kusuma Nuryani Tinumbia Ahmad Septiawan 1Department of Civil Engineering Faculty of Engineering Universitas Indonesia Kampus UI Depok Indonesia 2Study Program of Civil Engineering Faculty of Engineering Universitas Pancasila Serengseng Sawah South Jakarta Indonesia

This study assesses the potential passenger preference of the High-Speed Train infrastructure, which connects Jakarta – Bandung. The study aims to understand the potential HST passenger travel characteristics, which is important in predicting the HST demand. This study conducts a roadside interview using a stated preference methodology for several transport modes passenger serving Jakarta-Bandung, namely; private vehicle, train, intercity bus and paratransit. Moreover, the study extends in observing the short trip passenger preference. The analysis defines that the preferred fares are 300.000 (20 USD), which is increased compared to 2016 studies. The forecasting results of the demand for fast trains based on the probability of modal transfers amounted to 54,764 passengers per day with details of the number of trips Jakarta-Bandung was 27,005 while the Bandung-Jakarta trip was 27,759. The results for a significant difference between the total daily trips of Bandung-Jakarta and Jakarta-Bandung have already been seen since the initial statistical analysis where according to survey data, people who travelled Bandung-Jakarta were more elastic compared to Jakarta-Bandung trips. This finding shows clearly that the passenger traffic vehicle capitulates with the current road traffic highway conditions. Note that they are more uncertainty in condition on road traffic in comparison to the railway passenger. In more details, sensitivity analysis indicates that the passenger from Jakarta is more comfortable to shift using the HST compared to the passenger from Bandung. There is an indication that the Jakarta people have a higher value of time as they have a higher preference to shift toward faster transport mode compared to Bandung people. This information is also useful for operation policy, including ticketing differentiation based on the travel time period and travel origin-destination.

Ambon City, located in Maluku Island, experiences flood disaster every year. It has been considered that the flood in this city occurs more often compared to the other city in the same island. One of the river that is related to the flood occurrence in Ambon City is Wai Batu Merah River. This study aims to find appropriate structural measurement by using modelling simulation to control flood disaster in Wai Batu Merah River Basin. The modelling used HEC-RAS 5.0.7 software for coupled 1D and 2D hydraulic simulation. Flood discharge was calibrated by applying flood event in 2013. The SCS method was selected to generate flood hydrograph by using synthetic method. The records of water depth in the flood event were compared to the hydraulic model results and it showed good agreement. Based on the model, flood control scenarios i.e. normalization and dike were exercised for 25 year return period as required by government regulation. The combination of both scenarios can manage flood in Wai Batu Merah River Basin effectively. However it might need high cost to construct the structures. Therefore, it is necessary to have priority between the scenarios.

Analysis on calculation of Vehicle Operating Cost (VOC) at Gejayan intersection before and after fly over ring road operation in Yogyakarta

引用

IOP Conference Series: Earth and Environmental Science 2019年第1期340卷

作者： R E Wibisono M S D Cahyono A Muhtadi Program Study of Civil Engineering Engineering Faculty Narotama University Program Study of Civil Engineering Engineering Faculty Widya Kartika University

Gejayan intersection is located in Sleman Regency of Yogyakarta. Fly Over will be constructed at the intersection in the ring road of Yogyakarta. The nearest intersection to the east is Gejayan Intersection with a distance of 1573.11 meters. Gejayan intersection performance in 2018 has reached saturation by having Level of Service E. The more severe conditions will occur in the next 10-20 years. If it is planned using Fly Over on the ring road in Yogyakarta connecting Gejayan intersection, the vehicles flow must have other alternative by road widening. The most important step is to predict the Vehicle Operating Costs (VOC). After the Fly Over operation, VOC can be calculated to determine the cost saving. The scenario to predict VOC was 80% of vehicle volume would pass the Fly Over, and the 20% would still use the existing road. The results showed that the cost saving of Vehicle Operating Costs (VOC) of the existing road compared to the fly over use in 2019 was IDR 37,941,324,952. In 2039 the saving would be IDR 240,232,694,488. If the road was only widened, the cost saving of VOC in 2019 would be IDR 9,084,204923 and in 2039 would be IDR 72,107,188,198.
