Global liquefied natural gas expansion exceeds demand for coal-to-gas switching in paris compliant pathways
Authors: Yang Shuting , Hastings-Simon Sara , Ravikumar Arvind P 
Published: May 2022

Abstract
The shift from coal to natural gas in the power sector has led to significant reductions in carbon emissions. The shale revolution that led to this shift is now fueling a global expansion in liquefied natural gas (LNG) export infrastructure. In this work, we assess the viability of global LNG expansion to reduce global carbon emissions through coal-to-gas switching in the power sector under three temperature targets—Paris compliant 1.5 °C and 2 °C, and business-as-usual 3 °C. In the near to medium term (pre-2035), LNG-derived coal-to-gas substitution reduces global carbon emissions across all temperature targets as there is significantly more coal power generation than the LNG required to substitute it. However, we find that long-term planned LNG expansion is not compatible with the Paris climate targets of 1.5 °C and 2 °C—here, the potential for emissions reductions from LNG through coal-to-gas switching is limited by the availability of coal-based generation. In a 3 °C scenario, high levels of coal-based generation through mid-century make LNG an attractive option to reduce emissions. Thus, expanding LNG infrastructure can be considered as insurance against the potential lack of global climate action to limit temperatures to 1.5 °C or 2 °C. In all scenarios analyzed, low upstream methane leakage and high coal-to-gas substitution are critical to realize near-term climate benefits. Large-scale availability of carbon capture technology could significantly extend the climate viability of LNG. Investors and governments should consider stranded risk assets associated with potentially shorter lifetimes of LNG infrastructure in a Paris-compatible world.

Published: May 2022

Abstract
The development of Jenderal Ahmad Yani International Airport is performed on the north side of the airport. From that, a new taxiway will be available to support the flight activities. This study aims to analyze the geometry of the exit taxiway on the north side of the airport following the requirement issued by ICAO and FAA. The analysis was based on the type of aircraft mainly operated at Jenderal Ahmad Yani International Airport. The geometry analysis was performed on ICAO Three Segment Method and Landing Length Requirement. The location of the existing exit taxiway has not obtained an excellent functional percentage. Seventy-seven point seven percent (77.7%) of the planes are required to turn around before entering the apron. Therefore, changing the location and type of exit taxiway is recommended to maximize the runway’s performance in supporting the aircraft’s operational activities.

Abstract
Social history has shown that a city plays an important role in meeting human needs such as housing, service facilities, entertainment areas, and transportation networks. Therefore, the interaction between demand and infrastructure creates a traffic flow. Previous studies show that traffic flow is strongly correlated with land use types’ scale and operational characteristics. In addition, traffic volume can represent logistics distribution, which is one of the parameters to assess regional economic conditions. This condition prompted researchers to research to develop an interaction model between land-use intensity and traffic. The study was conducted in Bandar Lampung City, Indonesia, the economic center of Lampung Province, Indonesia. The methodology used in this study is the multiple linear regression analysis for origin-destination matrix. This analysis was performed using 23 parameters that could influence the model, but we try to find the most significant influence variables in this study. The process of evaluating some statistical parameters is considered as decision parameters. Finally, the analysis results show a strong correlation between land use and traffic volume in the city of Bandar Lampung, Indonesia the best model y = 62,3 + 2,275 x16 + 1,348 x20 with x16 is store building area, and x20 is the number of schools.

Abstract
Transport and tourism infrastructure are interrelated and have the ability to strengthen regional development and have a major impact on the rate of economic growth. East Kalimantan province has many potential mainstay tourism objects that have not been managed and promoted properly. The weakness of tourism in East Kalimantan lies in the transportation infrastructure. Access to several favorite tourist sites related to travel costs is considered relatively high, and the low accessibility of the road network impacts tourist visits to tourist attractions. This research is the basis for determining potential tourist destinations for the priority development of transportation infrastructure in East Kalimantan Province. Determination of tourist destination areas using the location quotient index approach (LQ > 1), namely the business sector that has the largest potential contribution to regional budget revenues in the transportation and tourism sector and reviewing policy directions contained in the regional regulations of East Kalimantan province regarding spatial plans for designated areas tourism is spread over an area of ± 97,442 ha. The areas that have been designated as transportation infrastructure developments are Kutai Kertanegara Regency, Berau Regency, Balikpapan City, Samarinda City, and North Penajam Paser Regency as the state capital.
Factor Analysis of Commuters’ Willingness to Use Public Transport
Authors: Baqarizky Nabila , Jachrizal Sumabrata R 
Published: May 2022

Abstract
Jabodetabek is the largest Indonesian metropolitan city with estimated daily trips of 47.5 million. According to Priadmaja, Anisa, Prayogi (2017), only 16.7% of the population uses public transport, contributing to 53% of traffic congestion in Jabodetabek. Furthermore, the continued increase of urban migration in search of employment, education, and other services has heightened the traffic congestion within the city and its surrounding areas. To mitigate this challenge, the Transit-Oriented Development concept was initiated to maximize the use of public transport. However, not many people prefer to travel using public means and therefore, this research sought to analyze the factors that influence the commuters’ willingness to use the available modes. Six variables were considered, including security, safety, amenities, affordability, equity, and regularity with limitations to KRL, MRT, and BRT modes. Questionnaires were issued to the respondents who filled the required information and sent them back. The collected data was analyzed with the help of multiple linear regression equations. The results indicated that amenities, regularity, equality, safety, and affordability variables influenced the use of KRL mode. Furthermore, the MRT mode was affected by regularity, affordability, and equality variables while the variables that influenced the use of BRT mode included amenities, safety, orderliness, and equality.
Index of Walkability to and from Public Transport Stops or Terminals in Greater Jakarta to Enhance Walking Environment
Authors: Putranto L S , Khuana R B 
Published: May 2022

Abstract
Almost all travel between an origin to a destination requires walking as first-mile and last-mile transport mode. Walking can be conducted either in the sidewalks, zebra-crosses, and pedestrian bridges. This paper adopts the index of walkability developed by D’orso dan Migliore in 2020 to be used for 150 respondents in Greater Jakarta. This index consists of three constructs (factors), i.e., practicability, safety and, pleasantness. A confirmatory factor analysis was used using principal component analysis in SPSS 27 and rotated using varimax with Kaizer Normalization. Instead of three factors in the original index, in this Indonesian adaptation, only two factors were extracted. Based on the discussion on this paper, it was recommended to increase the number of respondents to get a more valid result.

Published: May 2022

Abstract
In this current condition, people’s interest in using public transportation in Jember decreasing with a low load factor value below 50%. It is caused by several factors such as service coverage, lyn information, safety, fare, urban planning, and the quality of services provided by service providers to the satisfaction of public transport users. The Analytical Hierarchy Process (AHP) method is used to determine the weight of the factors that influence the interest of public transport users in Jember. The effort to be made is to formulate a policy strategy to support people who originally use private transportation switching to public transportation. The results showed that there were 5 selected factors: service coverage, lyn information, safety, fare, and urban planning. The weights of the factors that influence the interest of public transport users in Jember are 40% of the safety factor, 17% of the service coverage factor, 16% of the urban planning factor, 14% of the lyn information factor, and 13% the fare factor. Directions for future studies are presented.

Published: May 2022

Abstract
The development of the transit area in Poris Plawad is one of the government’s attempts in solving this issue. This implementation consists of construction plans that aim to increase the population of the area. This research aims to analyze the movement of pedestrians to and from the station and provide a recommendation of possible improvement in several aspects of the area’s services. In this research, the pedestrian facilities’ level of service (LOS) will be the standard reference to define how appropriate the facilities are. The Poris Plawad pedestrian area is categorized as LOS E and LOS F, thus needing improvements. The safety and serviceability of the pedestrian area also need to be evaluated as there are no sidewalks to be found. This research uses Vissim 11 as the leading software for the modelling of the system. The modelling made in this software will be used to compare actual field conditions with the behaviour of the model. The RSME value of the model is below 10%, which means that the model correctly represents its actual conditions. The author then implements several solutions to the existing condition and future conditions of the development area. The solutions for the existing conditions are building sidewalks and pelican crossings for the main road to decrease safety hazards. This increases the safety factors of the existing condition. The future condition will have an increased amount of pedestrians and a modified TOD layout plan. The solution for this is to make a design solely for pedestrians with full attention to their safety and comfort.
Traffic management at intersection to minimize dispersion of air pollution
Authors: Ambarwati L , Indriastuti A K 
Published: May 2022

Abstract
One of the consequences of higher mobility is the increase in air pollution. The increase in traffic volume at intersections impacts delays and congestion, thus producing higher air pollution concentrations. This research aimed to identify intersection performance and analyze air quality at existing conditions, then propose traffic management scenarios that increase intersection performance and reduce air pollution at a time. This study was taken on Soekarno-Hatta – M.T. Haryono – D.I. Panjaitan intersection, in Malang.
The intersection performance was at the worst level of service (LOS F) for each approach from traffic analysis using the Indonesian Highway Capacity Manual. At this condition, the prediction of air pollutant parameters was out of standard level. The CO concentrate was lower than the standard level, while NO was higher than the standard level. Traffic management was proposed by controlling the movements at the intersection approaches and the number of phases at the intersection. The third alternative can improve intersection performance from F to C and decrease air pollution. The concentration reductions are about ±37.4% for NOx and ±61.3% for CO from the road median to the end of the road.
Impact of Overloading Vehicle towards the Level of Service on Freeway Segment (Case Study: JORR KM 27 to KM 23)
Authors: Sugari Herlin , Kusuma Andyka , Purnomo Robby Yudo 
Published: May 2022

Abstract
The congestion problem that occurs on the road is one of the indicators to determine the level of service. Approximately 20% of all traffic congestion is due to the existence of shockwave jams or phantom jams. One of the factors causing the shock wave phenomenon is the speed differences between heavy vehicles and light vehicles (Garber & Hoel, 2009). On the other hand, the Over Dimension and Over Loading (ODOL) Vehicle worsened the situation by reducing operational speed due to the exceeding load. Indonesia Traffic Police stated that throughout 2019 there were 136.470 vehicles out of 1.376.956 offences that were ODOL vehicles. This research aims to identify the effect of overloading vehicles and the volume of heavy vehicles on creating shock wave phenomenon that led to the lower level of service. Microsimulation modelling is carried out to obtain the resulting level of service from heavy vehicles volume using the primary data from the data collection. The result shows that the large volume of heavy vehicles exacerbated by the presence of ODOL vehicles can cause a temporary change in road speed and lead to a decreased level of service.
Behavior Model Analysis of Pedestrians and Cyclists Mode Selection Base on Active Transportation on Universitas Jember Tegalboto Campus
Authors: Sulistyono S , Kriswardhana W , Arianto J B 
Published: May 2022

Abstract
The University of Jember as one of the campuses that have a high traffic volume is trying to realize a “Green Campus” through the “Ring the Bell” program. However, this vision has not been implemented optimally because there are still many campus residents who do not use active modes of transportation (walking & cycling) even though sidewalk facilities are available. This indicates that the behavioral preferences for choosing active transportation modes for the residents of the Jember University campus are still unclear. Therefore, this study aims to analyze the behavioral model of pedestrian and cyclists mode selection based on active transportation at the Tegalboto Campus, Jember University. The primary data collection of residents’ preferences was obtained through the TPB (Theory Of Planned Behavior) questionnaire. SEM model (Structural Equation Model) was applied in the behavioral analysis process to determine the interaction between the independent variables of TPB as a whole. The results of behavioral modeling show that intention is the variable that most influences the behavior of campus residents in using active transportation modes, while attitude is the variable that most influences intentions than subjective norms and perceptions of behavioral control.

Study of Refinancing Scheme On Toll Road Infrastructure (Case Study: Gempol-Pandaan Toll Road)
Authors: Sunarya Nesa Nurhadi , Karsaman Rudy Hermawan , Santoso Idwan 
Published: May 2022

Abstract
PT. Jasamarga Pandaan Tol (JPT) is a toll road operator that officially operates the Gempol-Pandaan section located in East Java. JPT made adjustments to the concession scheme through a business plan addendum in March 2015, wherein in this model the financing process involves the use of shareholder loan funds. The profit generated by this business plan model is considered to have a high level of sensitivity during the loan tenor and has the potential for default to creditors. To avoid this, it is necessary to compare other alternative financing methods such as Refinancing and Infrastructure Investment Fund (IIF). The method used is financial feasibility analysis by taking into account the value of NPV, B / C, PP, IRR, WACC, and ROI as parameters. Based on the results of the financial feasibility analysis, the refinancing model provides better PP and ROI parameter values than the business plan model.

Abstract
Malang Kota Baru Station is located in the center of Malang City with a variety of land uses occurring around the area. The concept of an area supports aspects of building density, diversity of land use, and the proximity of the area to transit points, one of which is Transit-Oriented Development (TOD). The purpose of this research is to obtain a development strategy that can be carried out in the area. The TOD principle approach is used in the Area of suitability analysis. The AHP method and SWOT analysis are used to obtain a regional development strategy. The results of the suitability analysis show that almost all of the existing condition variables are not under the TOD principle parameters. Furthermore, all parameters are used in the AHP analysis, and the order of priority for regional development is obtained, namely: diversity, design, and density. Determination of the grand strategy for regional development based on IFAS and EFAS obtained recommendations for aggressive maintenance strategy. This strategy needs to be carried out in regional development by maximizing various opportunities, to resolve or minimize internal weaknesses that occur.
A Comparison Analysis on Car User Decision When Faced with Different Congestion Pricing Policy (Case Study: Jakarta Metropolitan Area)
Authors: Alvinsyah  , Fathurrizqi Muhammad 
Published: May 2022

Abstract
This research aims to analyze the car user’s decision in their mode choice when faced with two different congestion pricing, namely Road Pricing (RP) and Parking Pricing (P2) policy scheme. The comparison analysis is conducted through the developed binomial logit model both for RP and P2 policy schemes. Data is collected by utilizing a stated preference survey, where the car user is asked their preference towards the mode choice on a given set of price and timesaving combination for both policies. Then the utility function for each policy is established by conducting some statistical procedures to have a feasible and reasonable model. Having set the utility functions, the validity test is carried out to the developed model using a different set of data from the survey. Further analysis is done to select the model that satisfies the statistical feasibility and the validity threshold number. Comparison to both different choice models yields different decisions represented in the form of shifting mode percentages. The research results show that the RP policy scheme tends to shift the car user higher than the P2 policy scheme at the same total additional charging fare.

Published: May 2022

Abstract
The application of an intermodal transportation integration system will make it easier for people to carry out activities, guarantee travel travel time, and optimize the use of public transportation, and have an impact on reducing the use of private vehicles which can affect road performance. The policy for implementing the transportation integration system needs to be considered in order to accommodate travel activities by following regional development conditions. This study aims to determine the management integration and the constraints in implementing the transportation integration system. This study uses a qualitative method by taking into account the aspects of the policy which involve elements of regulators, operators and consumers. This research shows that the regulator is able to carry out the management of the transportation integration system through the implementation of government affairs in the transportation sector, however, there are obstacles in the form of regulatory linkages, coordination and limited authority. So it is necessary to optimize the role of regulators to be able to coordinate intensely with public transport operators in order to realize an integrated transportation system management that can meet the travel needs of the community.
Verification of vertical temperature profiles in the COSMO and ICON models with available observational data
Authors: Gochakov A V , Tokarev V M , Kolker A B 
Published: May 2022

Abstract
This paper presents results of numerical estimates of vertical temperature profiles in the COSMO and ICON NWP models. Data from two vertical profilers, an MTP-5 microwave temperature profiler and a classic AVK-type radiosonde, are used for the estimates. Mean errors, correlation coefficients, and root-mean-square errors are calculated for different seasons. The simulation results are analysed depending on configurations of the horizontal resolution of the models and between the models. The estimates are plotted, and comparisons are made between the models using each of the measurement types: between different measurements for each model. The response to spatial variability in the measurements and model grid cells is assessed. Conclusions are formulated by comparing the quality of reproduction of the atmospheric boundary layer between the models and the model configurations. The findings provide useful information for the interpretation of modeling results by forecasters.
