Combinatorial mappings of exclusion processes
Authors: Wood Anthony J , Blythe Richard A , Evans Martin R 
Published: February 2020

AbstractWe review various combinatorial interpretations and mappings of stationary-state probabilities of the totally asymmetric, partially asymmetric and symmetric simple exclusion processes (TASEP, PASEP, SSEP respectively). In these steady states, the statistical weight of a configuration is determined from a matrix product, which can be written explicitly in terms of generalised ladder operators. This lends a natural association to the enumeration of random walks with certain properties.Specifically, there is a one-to-many mapping of steady-state configurations to a larger state space of discrete paths, which themselves map to an even larger state space of number permutations. It is often the case that the configuration weights in the extended space are of a relatively simple form (e.g. a Boltzmann-like distribution). Meanwhile, various physical properties of the nonequilibrium steady state—such as the entropy—can be interpreted in terms of how this larger state space has been partitioned.These mappings sometimes allow physical results to be derived very simply, and conversely the physical approach allows some new combinatorial problems to be solved. This work brings together results and observations scattered in the combinatorics and statistical physics literature, and also presents new results. The review is pitched at statistical physicists who, though not professional combinatorialists, are competent and enthusiastic amateurs.
Uncertainty in classical systems (with a local, non-stochastic, non-chaotic origin)
Authors: Jeffrey Mike R 
Published: February 2020

Abstract
Decisions made by two (or more) independent players in a dynamical system can result in an indeterminable, yet non-stochastic, outcome. The mechanism can be presented as a thought experiment in which two pilots attempt to steer a spacecraft but, in stabilizing its pitch and yaw, lose all knowledge of its forward motion. It is useful to think of this pilots’ dilemma as a classical analogue of Schrödinger’s ‘cat in a box’ thought experiment. In both, the outcome of a life or death scenario is indeterminate until it is directly observed, but in place of the probabilistic radioactive source in Schrödinger’s problem, the discontinuous action of the pilots’ decisions create the classical indeterminacy. We discuss the wider implications of the phenomenon, such as predicting indeterminate scenarios in optimal transport or other network problems. The behaviour only becomes apparent when a system’s dynamics is sufficiently taken into account.

Abstract
This paper deals with the innovation of road construction materials by the use of polyethylene terephthalate (PET) as asphalt mixtures. The PET was obtained from plastic bottles waste. The purpose of this research is to investigate the effects of the PET on Marshall parameters on asphalt concrete pavement. The wet method is used in this research. It means that PET plastic material is directly mixed into asphalt when the asphalt is heated, then aggregates are added. In this research, asphalt with penetration of 60/70 is used. Its optimum asphalt content (OAC) is 5.7 percent while The percentages of the added PET are 3 percent, 4 percent, 5 percent, 6 percent, and 7 percent of the asphalt by weight. The results show that the addition of PET plastic waste into the mixture has a significant positive effect on the Marshall parameters of asphalt concrete pavement. The addition of PET waste has been able to increase the value of other Marshall parameters, including Voids in Mix (VIM), Voids in Mineral Aggregates (VMA), Voids Filled with Asphalt (VFA), Flow, and Marshall Quotient (MQ). This research result will contribute to a significant outcome in emerging a sustainable material for road infrastructure.
Designing for Fire Safety and Ventilation in Warm Humid Climate, Case Study: Library Building of Universitas Atma Jaya Yogyakarta, Indonesia
Authors: Prasetya Ade 
Published: February 2020

Abstract
Fire safety is imperative for public buildings. Previous studies suggested that fire responsive building should limit the provision of oxygen to avoid hazardous flashover. However, due to warm humid climate, most Indonesian low-rise buildings are designed to maximize natural ventilation by constructing open stairs instead of fully enclosed stairwells. Therefore, those facts incite questions on how fire safety issues should be addressed in warm humid climate buildings. In response, this research employs a case study of five stories Library of Universitas Atma Jaya Yogyakarta, Indonesia. Furthermore, this paper introduces FDS+Evac to predict the behavior of fire spread toward occupants during egress. Research combines the mandates of fire safety along with natural ventilation by deploying two separate conditions: a) under fire incident, and b) daily (normal) condition. Under fire incident, the experiment measures egress safety indicators; degree of visibility, air temperature, and FED (Fractional Effective Dose), whereas for daily condition air velocity and its distribution are accounted. Experiments are conducted by devising three concepts: 1) existing, 2) passive protections; hung walls, enclosed stairwell, and smoke cavities, and 3) active protections; exhaust fans, air curtains, and sprinklers. Result shows that smoke, high temperature, and poor visibility are best solved by providing air cavities, whereas toxicity is reduced by increasing ventilation rate. Moreover, natural ventilation is satisfied since existing openings are unchanged.

Published: February 2020

Abstract
The online taxi bike gives some convenience to customers since its first launch. The demand for using online taxi bike from the public is quite high. Unfortunately, the high demand is not accompanied by the adaptation of urban space. Streets and circulation nodes begin to be filled with online taxi bikes which are hanging or waiting for passengers. This activity causes congestion and misuse of urban infrastructure. This development must be maintained by the government so that the presence of online taxi bike can run optimally without harming any parties. This study will examine how significant the impact of the presence of online taxi bike in urban areas is related to the use of space and urban infrastructure. This study uses qualitative method and is done by observing several strategic points in the city which were synthesized through the map. The research is complemented by literature studies and enriches the latest information through the city news. The results prove that the existence of online taxi bike can reach the blank spot of the city and complete the public access to the destination. Nevertheless, its existence can lead to conflict, especially with other public transportation services. On the passenger’s point of view, the presence of online taxi bike makes the trip easier. To reduce potential conflict, the meeting between online taxi bike community and conventional taxi bike can be arranged by the government.

Abstract
Floods are disasters that often hit cities in Indonesia. Even in certain cities, flooding is a recurring disaster. Kendari City is a service and trade city in Southeast Sulawesi Province which has a vulnerability to repeated flood disasters in urban areas including 10 Districts, which are still included in the Wanggu River Basin. This urban area experiences the phenomenon of urbanization, namely population growth and high land use change and land ownership transfer. The development of residential areas as a consequence of population growth, is also a cumulative factor triggering the flood disaster in the Wanggu River Basin. This study aims to determine the development of the expansion of flood areas in the Wanggu watershed in a time series (period 2007 - 2017) and how they impact the development of Kendari City. This research will also investigate the impact of land use change and the impact of urban population growth on the expansion of flood disasters. The method used is the collection of qualitative and quantitative data, observation, and verification in the field, to map analysis using High Resolution Satellite Imagery to determine changes in land use in the Wanggu watershed area. The expected outcome of this research is the mapping of areas that are vulnerable to the risk of flooding, especially in urban areas to the resilience strategy chosen as one of the city’s resilience efforts against disasters.

Canyon effects in urban configurations: tropical context study
Authors: Yola Lin 
Published: February 2020

Abstract
The increase of the Urban Heat Island (UHI) is a continuing phenomenon in dense cities. Technically, the building of heat gain generated from modified solar radiation in tropical urban spaces requires the scientific solution. The investigation on the behavior of urban microclimate, especially solar radiation in the urban canyon, was comprehensively investigated by early urban energy studies. However, the solar radiation trapping effect as the behavior of solar radiation in different type of urban configurations is still unclear. This study, therefore, aims to investigate the impact of urban configurations on the solar radiation performance in Kuala Lumpur tropical context. By using ENVI-met V3.1, this study simulates four urban configurations situated in two scenarios of canyon directions; East-West and South-North. The results recorded that the short wave and long wave solar radiation varies in a different type of urban configurations. It concludes that besides the Sky View Factor (SVF) and Height to Width (H/W) aspect ratio, the direction of urban canyon towards the exposure of the source of solar radiation significantly influences the solar radiation trapping effect. This finding will be a significant reference to strategies for the urban configuration to improve the microclimate in the urban spaces and mitigating climate change.

Authors: Haribowo Riyanto , Dermawan Very , Fitrina Halita 
Published: February 2020

Abstract
Decreasing river water quality due to the environmental conditions around the river can cause changes in the value of river benefits and endanger the environment. Thus, it becomes necessary to improve river water quality management by monitoring water quality. The purpose of this study is to model predictions of water quality conditions. The method is by analysing the parameters of water quality (BOD, COD, DO, pH, temperature) influenced by rainfall, catchment area, and land use. Data analysis was performed by the artificial neural network (ANN) method, using the Matlab R2014b software. In the process of network development, the most effective model was obtained with a variation of 75% training data with 5 hidden layers and a maximum epoch of 2000. From the results of the model, the relative errors (RE) for BOD, COD, DO, pH, and temperature were found to be 7.80%, 6.33%, 6.83%, 1.92% and 1.05% respectively, with an overall average of 4.79%. Because this RE value is quite small and less than 5%, it can be concluded that the artificial neural network method is quite effective for monitoring water quality conditions in the study area.
Assessment on the efficiency of sediment flushing due to different timings (a case study of Mrica reservoir, central Java, Indonesia)
Authors: Legono Djoko , Hidayat Fahmi , Sisinggih Dian , Tri Juwono Pitojo 
Published: February 2020

Abstract
The issue of the sedimentation problem of reservoirs has been growing significantly during the last two decades, particularly in areas where human activity increases pressure on the land. However, some researchers believe that such situation is also (partly) affected by the significant shift in hydro-meteorological conditions, accompanied with higher rainfall erosivity and hence an increase in land erosion. Various efforts have been suggested to control the erosion process, whether by sediment control at the catchment area or placing a ground sill and/or check dam in the stream. However, additional activities to remove sediment from reservoirs through sluicing, flushing, and dredging are often still necessary. This paper deals with the evaluation of the effectiveness of flushing at different timings. The results showed that the uncertainty of the sedimentation process and the hydrograph inflow characteristics are dominant factors affecting the problems. A further recommendation is to determine the procedure for establishing reliable advance timing that is considered most efficient for carrying out the flushing activities.

Published: February 2020

Abstract
Pervious concrete is an alternative to reduce surface runoff in urban areas. To examine effect of different materials on the void ratio of pervious concrete is studied in order to evaluate the efficiency of pervious concrete solving surface runoff problems. Various materials have been used in mix proportion of pervious concrete. Different size of aggregate, the use of supplementary material for cement, recycled aggregate as an alternative to replacing natural coarse aggregate, and fiber usage were utilized in a series of experiment to evaluate the value of void ratio that greatly affects the effectiveness of pervious concrete to cope surface runoff in urban areas. The result shows that the size of aggregate strongly affected the void ratio of pervious concrete, while the effect of the use of supplementary material for cement in pervious concrete to its void ratio was not significant. However, pervious concrete made of recycled aggregate proved to have a higher void ratio compared to pervious concrete using natural coarse aggregate. When utilizing fiber in mix proportion of pervious concrete, the higher rate of fiber reduced its void ratio.

Published: February 2020

Abstract
A study of water balance in the Upper Konto sub-watershed was carried out to determine the potential for water availability and its use in the multisector water needs. Rainfall was converted into discharge using the F. J. Mock method, compared with the observed discharge, and calibrated with the Relative Error, Root-Mean-Square Error (RMSE), Nash-Sutcliffe Efficiency (NSE), and Correlation Coefficient (R). The potential for water availability was calculated based on an 80% dependable flow using the Weibull probability method with an amount of 22.41 m3/sec, equivalent to 706.622 million m3/year. The amount of water demand within a period of 25 years in scenario 1 (calculated based on data and increasing according to the growth rate) is 95.090 million m3/year, while in scenario 2 (based on the assumption that domestic, non-domestic, and industry demand increased while fishery, agriculture, and livestock demand remained constant) is 93.419 million m3/year. The results of the water balance analysis showed that the potential for water availability is sufficient for all multisector water needs, or indicates a surplus condition for 25 years (2017-2042).

Every year downstream area such DKI Jakarta city suffers from flood and it could disturb the economic life. High sea level, increasing number of rains, land subsidence, and conversion land use into built up area around upstream caused some damage flood in downstream area. To minimize the impact, the government of DKI Jakarta Province already constructed 36 polders system since 1973 and 11 polders planned to construct. Some of those polders have retention pond and other components to support the system. Those built up polders needs routine maintenance according to its budget in order to keep its function. Guideline to allocate budget for each polder’s yearly maintenance not yet available. This research analyses indicators that give impacts to polder’s services by using PLS and PCA Method, which based on 160 samples of questionnaire and result of site survey. As an object of this research, 8 polders in DKI Jakarta which have retention pond, pumps, water gate and trash rack are chosen. They are Polder Grogol, Polder Teluk Gong, Polder Melati, Polder West Setiabudi, Polder Pulomas, Polder Tomang, Polder North Sunter and Polder South Sunter. As a result, there are 23 indicators that affected in service index of polder system.
