Published: February 2021

Abstract
The random utility maximization (RUM) is a widely used principle to study customer behaviors derived from econometric theory. The mode choice problem in transportation planning has been intensively studied to explore the choice behavior of travelers. In the demand analysis, market shares among transport modes are substantially used for public transport planning and operation. Therefore, this study is a preliminary analysis of the modeling complex mode choice behaviors among motorcycle and bus system so-called Trans Koetaradja by considering specific attributes of mode, households, and individual sociodemographic attributes. The developed model of mode choice is used to explore the effect of specific attributes of mode, households, and individual sociodemographic attributes on traveler’s mode choice behaviors and its contributing factors. Using the Revealed Preference (RP) data collected in Banda Aceh, we formulate Binary Logit (BL) to identify and evaluate the effects specific attributes of mode, households, and individual sociodemographic on mode choice. These results confirm that there is a substantial contribution of the specific mode attributes of the individual in determining selected mode choice. The specific attribute of motorcycle mode preference such as travel time (TT) and distance of destination (DD). Findings further confirm that individual sociodemographic variable including dummy young Age (DYA), dummy has elementary education background (DEB), dummy has low-medium income (DIN), dummy owned motorcycle (DOM) and dummy has driver license (DDL) have a statistically significant alert to the selecting mode choice of motorcycle.

Abstract
The area of Masjid Raya Baiturrahman is an area that is integrated with public space, pedestrian pathway, and public transportation infrastructure namely Halte Trans Koetaradja. This area is always crowded because of the Masjid Raya Baiturrahman besides as a center of Islamic worship also as a center of Islamic tourism in Banda Aceh. This area is always crowded by motorists and pedestrians who visit and perform activities in the area. Because the still mix of motor vehicles and pedestrians makes the area at certain times very dense so it is not safe and comfortable for pedestrians. This research aims to identify the existing conditions of the pedestrian street in the area of Masjid Raya Baiturrahman Grand and also identify the characteristics of pedestrian movements to determine the level of service from the pedestrian path. This study was conducted using a table based on the list of Ministerial Regulation of Public Works No. 03 the Year 2014 and also the Department of Transport (DOT) to identify the existing conditions of the pedestrian path in the area of Masjid Raya, then conducted a review of the characteristics of pedestrian movements using the formula of pedestrian speed, pedestrian flow and also pedestrian density. The results of this research appointment that the pedestrian pathway in the area of Masjid Raya Baiturrahman when reviewed from the existing service level, it is still a level of service A, but if the review of existing conditions then there is an improvement to the pedestrian pathway. This is because the supporting facilities have not been compactor to the pedestrian pathway by the standard guidelines.

Published: February 2021

Abstract
Indonesia is one of the most vulnerable countries in the risk of natural disasters from the standpoint of geography, geology, climatology and demography. The geographical position of Indonesia is located at the confluence of 3 main tectonic plates and includes the Pacific Ring of Fire, and has more than 500 volcanoes, of which about 128 are still active. Some of the disasters that caused severe damage, large casualties and high losses included the earthquake and tsunami in Aceh (2004), the earthquake in Yogyakarta (2006), the earthquake in Padang (2009), the earthquake in Lombok (2018) and earthquake, tsunami and liquefaction disasters in Palu (2018). For this reason, it has become a necessity for the Indonesian people to learn from this disastrous experience of disaster by identifying all aspects related to risk and vulnerability to improve the ability of communities to cope with disasters. This study, which is based on the results of a study of a number of disaster studies, seeks to revisit several disaster events in Indonesia with a special review of the concept of disaster mitigation and its application to minimize disaster risk in urban areas. The results of the study show that the concept of disaster mitigation has been planned in several cities in Indonesia but there are still weaknesses in its application when a disaster occurs. This result is expected to be one of the references in improving the quality of urban disaster mitigation planning in Indonesia.

Abstract
Unsignalized intersection is the most operated traffic facility in Indonesia including several small-medium cities like Bireuen. The unsignalized intersection is mainly characterized by the complex maneuver mechanism by road users. The RSU Fauziah intersection is one of the most crowded intersections within the city center. This unsignalized intersection seems does not fit with current traffic demand. Indiscipline driver’s movement and the rejection gap by the driver leads to deteriorating the capacity and level of service (LOS) of the intersection. Therefore, this work proposes to investigate the deterioration of capacity and level of service of targeted unsignalized intersection considering current traffic facility (unsignalized) and tested roundabout type traffic operation. The study was conducted at RSU Fauziah unsignalized intersection which located at the city center of Bireuen, Aceh Province, Indonesia. Using peak hour traffic data recorded using a video camera, the capacity was evaluated using the Indonesian Highway Capacity Manual (IHCM, 1997) for the existing traffic performance and simulating using VISSIM for trial implementation of roundabout. While the level of services (LOS) was examined using the Ministry of Transportation Decree (2006). The result of analysis demonstrates that the capacity of unsignalized slightly increases by 24.5% while the delay and level of service are significantly reduced to 39.2%, and improved from E to C, for delay and LOS, respectively. It can be concluded that the improvement of the existing condition by implemented a roundabout could improve the capacity and LOS of an existing unsignalized intersection.
The unit price of building changes to different design of seismic importance factors
Authors: Mastura C A W S , Mubarak M , Abdullah A 
Published: February 2021

Abstract
The design of a building needs to accommodate the potential for earthquake risk. The function and utilization of buildings are closely related to the risks caused by earthquakes, especially for people using the building. In the design process, load changes due to utilization are accommodated through an index value called seismic importance factors (SIF). The application of the index will directly affect the structural dimensions of a building. Thus, the amount of building unit price (BUP) needed will also vary according to the function of the building. This research was conducted to analyze changes in BUP on some seismic importance factors in a building structure design. Changes in unit prices were explained by applying the price index approach in the form of the building unit price index (BUPI). This study was applied to a six-story building using reinforced concrete structures and following earthquake load conditions in four seismic zones in Aceh Province. The BUPI was analyzed based on comparing a building unit price (BUP) to the reference BUP that was set from the building designed with the lowest SIF index in the initial seismic zone. The analysis results show that the increase in the SIF indices will potentially increase the BUP to 6 % (IDR. 105,061.25) for SIF 1.00 to 1.25, while the increase in costs for SIF 1.25 to 1.50 was 4 % (IDR. 84,507.32). The BUPI values have clearly explained how the building unit price increases following the SIF indexes increase.

AbstractThe use of fiber reinforced polymer (FRP) has been implemented as an alternative for strengthening and repairing methods. Nowadays, the use of natural material for FRP has been developed in order to minimize the disadvantage effects to nature due to synthetic FRP material and economic reason. In this paper, an experimental study was carried out to evaluate the bond strength of abaca fiber as natural reinforced polymer (NFRP) material in reinforced concrete (RC) beams. The test specimen was a beam that had cross-section area of 100 × 100mm2and 300mm length. Single rebar was used in this study with 10mm diameter of rebar. Artificial crack was applied in order to consider the initial crack by using cardboard between the concrete. Two externally bonded strengthened beams with a different type of abaca fiber arrangement, bond length, and thickness were applied on the concrete surface. The test was conducted by applying a tension load on the beam until the specimen reach its failure. The results showed that the bond strength decrease as the bond length becomes longer because the maximum load was almost constant for different bond length. The maximum load was approximately around 4 tf for short and long bond length. The compatibility of abaca fiber and rebar was also monitored. Both abaca fiber and rebar able to stand the load compactly. Abaca fiber composite laminate had a similar trend with rebar at the same location where an artificial crack was made. Furthermore, the arrangement and thickness of the abaca fiber composite laminate affected the results.

Abstract
Pidie Jaya earthquake occurred on December 7, 2016 caused the damage of many building structures. Therefore, it is important to assess the performance of building structures in resisting the earthquake load. In this paper, the performance assessment of two building structures, which were the Multipurpose Hall Building that has been deformed permanently and Prosecutor’s Office Buildings that have been experienced some flexural and shear cracks was conducted. The study was started by performing site, design document, and as built drawing assessment. The building structures were modelled as space frames using ETABS software and the data obtained from the site was inputted. The design response spectrum recommended by SNI 1726:2019 was used as spectrum demand. The performance of building structures was assessed by conducting a non-linear push over analysis in two X and Y directions until the structures near to collapse and capacity curves were obtained. By comparing the capacity and demand spectrums in Acceleration-Displacement Response Spectrum (ADRS) format, then the performance points of the structures were obtained based on ATC-40. Based on the inter-story drift at the performance point, then the performance levels of the structures were determined. The assessment results showed that the performance level of the Multipurpose Hall Building structure is Life Safety, while the Prosecutor’s Office Building structure is Damage Control.
A proposed method for calculating dimension of irrigation channel section
Authors: Yulianur BC A , Fauzi A 
Published: February 2021

Abstract
In general, the cross section of irrigation channels in Indonesia is planned to be trapezoidal. The calculation of the dimensions of the trapezoidal section uses the quadratic equation when calculating the hydraulic depth in the channel. Calculations using quadratic equations can produce imaginary numbers if the discriminant value is negative, resulting in a failed calculation of channel dimension. This study proposes a method for calculating the dimensions of a trapezoidal cross-sectional irrigation channel, in which the discriminant value of quadratic equation is not negative. The analysis is carried out on all formulas that produce the independent variable for the discriminant value in the quadratic equation. The independent variable is the mean flow velocity in the channel or the channel base slope. This study produces a formula for calculating the mean flow velocity in a channel as well as a formula for calculating the channel base slope which results do not result in a negative discriminant value. Thus, the calculation of the hydraulic depth in the channel has not failed and the calculation of other channel dimensions can be continued.

Abstract
Monitoring in-service road surface conditions is a part of road pavement maintenance. The most effective maintenance type will save costs and time. Road damage usually occurs on roads that have reached the design age, but some roads have been damaged before reaching the design age. To assess road damage, several methods can be used. The most widely used method in Indonesia is the Bina Marga method and the PCI (Pavement Condition Index) method. This study aims to compare both methods, in terms of accuracy and workability, in monitoring the surface condition of Prof. Ali Hasyimi street, which is located in the city of Banda Aceh. The data required for these two methods is the primary data, which are geometric, visual road damage, and traffic volume. Based on this study’s results, the Bina Marga method is easier and faster to use, while the PCI method is more detailed to utilize. In terms of accuracy, both methods relatively have the same accuracy.

Published: February 2021

Abstract
One of the problems with infrastructure in the City of Balikpapan is the inadequate drainage system and is one of the causes of flooding in the City of Balikpapan. Drainage problems in the city of Balikpapan concentrated in the central area of the city, one of which system of drainage that is located in the city center is the Ampal/Klandasan Besar Basin. In that drainage system, there is one of the sub-basin where the majority of its land use is built-up area, namely the Posindo Sub-basin. This study aims to analyze the effect of land use on high floods that occurred in the Posindo Sub-basin. Flood discharge due to rain was analyzed using the HEC-HMS program. The results of the hydrological discharge of the HEC-HMS model are compared with the cross-sectional capacity of the channel so that the flood height above the channel is obtained. Based on the analysis of channel capacity and flood discharge, the results show that the drainage channel in the Posindo Sub-basin is unable to drain the hydrological discharge due to rain without overflow.

Abstract
Following the development of transportation technology, steady road infrastructure is needed. The choice of construction type is a crucial point for the expected quality. Road construction consists of flexible and rigid pavement construction. Rigid pavement has higher durability and is produced from concrete, a strong, flexible, and fire-resistant material. Lightweight concrete, containing high amounts of pores, can be produced by using lightweight aggregate or a mixture of lightweight-coarse aggregate fulfilling the requirements for compressive and flexural strength. This study evaluated the compressive and flexural strength of lightweight concrete without coarse aggregate as a rigid pavement material. This study used specimens from type I Portland cement for compressive and flexural strength test, in 0.5 water-cement ratios and the specific gravity of 1.0. The result revealed a compressive strength value of 38.91 kg/cm2 and a flexural strength value of 1.32 MPa. Based on the results obtained, it was concluded that lightweight concrete material fulfilled the general specification criteria for the compressive strength requirements of the cement-treated subbase (CTSB).

Published: February 2021

Abstract
Membrane separation technology has been extensively applied in separation processes. Improving membrane hydrophilicity plays a significant role in mitigating fouling phenomena and maintain membrane filtration performance. Fouling is a pore blockage of the membrane due to the interaction between hydrophobic molecules and membrane surface that cause membrane flux declining, shorter membranedurability, and increasing energy consumption. Incorporating inorganic particles to enhance membrane hydrophilicity is very attractive nowadays. Inorganic particles have unique characters due to their small size, excellent mechanical properties, and hydrophilic nature. This research aims to improve PES membrane filtration performances by employing nanocarbon and Fe2O3 as an inorganic additive. The membrane manufacturing process was carried out using a phaseinversionmethod., especially non-solvent induced phase separation (NIPS). The resulted membranes were analyzed by filtration soy protein solution to evaluate protein permeation flux and flux recovery ratio (FRR). The result experiments showed that PES/Nanocarbon could provide the highest FRR of up to 76.46%.
