Authors: Tulegenova A A , Andreenko T I , Rafikova Y 
Published: October 2019

Abstract
The use of woody biomass obtained from pruning and removal of perennial agricultural plantations for energy needs is a relatively new direction, which is now actively explored and developed in Europe. In Russia, horticulture and viticulture is also a traditional direction of agriculture in the southern regions, in particular, in the Republic of Dagestan. Dagestan is a volatile region with a variety of problems in the fuel and energy complex. The solution to these problems may become the use of renewable energy resources in the region. The paper presents the methodology for assessment of bioenergy resources in the region with the use of spatial analysis. The main purpose is to determine the optimal economically and technologically available energy technology for the estimated energy resource. The results show the high importance of social and economic factors for the development of renewable energy in the region, which is not typical for the other regions of Russia and should be taken into account in the further development of the methodology of multi-stage bioenergy resource assessment.
Developers’ perception of cost drivers influencing project cost performance on Surabaya high-rise residential, Indonesia
Authors: Chicoca D , Utomo C 
Published: October 2019

Abstract
Good cost performance is one of the fundamental criteria of a successful project. The major challenges developers have in this process is to balance the budget and project cost performance. Most of the scholars agreed that the construction indu stry in any country is complex because it involves a broad range of stakeholders and has wide-ranging linkages with other areas. Some of these factors are also unknown at the project level, which create difficulty for project managers to assign a favourable contingency cost. Therefore, this work came to establish factors influencing project cost performance of high-rise residential development through macro indicators based on developer’s perspective. It sought to identify these factors in an effort to shed more light on how cost drivers affect project cost performance. From the study findings, there are seven cost drivers. These drivers are analysed based on significance and impact using multiple regression analysis. The top most in terms of significance are property market and construction industry, project characteristic factor, socio economic factor and project component costs factor. The least one out of the seven factors is the statuary regulation factor. In relation to impact, project stakeholder factor has the highest impact, followed by the property market and construction industry, project characteristic factor and project component costs factor. The least one is socio economic factors.
Risk analysis of traffic congestion due to problem in heavy vehicles: a concept
Authors: Kesuma P A , Rohman M A , Prastyanto C A 
Published: October 2019

Abstract
One of the most common problems on roads is traffic congestion caused by problems with heavy vehicles (e.g. trucks, trailers). The consequences of this problem often harm the wider community, both in material and non-material forms such as fuel waste and loss of time. Several previous studies have tried to look for factors that cause traffic congestion, but it has not been able to provide a complete understanding of the root causes and who are the stakeholders who must have an important role in solving this problem. This study aims to develop a research framework to get more better understanding about congestion caused by problems with heavy vehicles, which can be categorized as a type of non-recurrent congestion (NRC) that is dynamic and unpredictable. Risk management prioritizes a proactive approach before an event occurs, so the impact of risk can be minimized. Probability and Impact Matrix techniques are used to determine risk priority. Furthermore, to find the root causes of traffic congestion problems, the Fault Tree Analysis (FTA) method and Social Network Analysis (SNA) are considered to be quite potential to be used to describe complex patterns of relationships among stakeholders. The results of this study are expected to provide more complete information to understand the problem of congestion due to the problem of heavy vehicles, so that a more comprehensive solution can be formulated.

Published: October 2019

Abstract
The sustainable concept of housing supports a house in reducing the dependence on fossil-based energy. The environmental impact of a housing building, particularly CO2 emissions, depends on the house overall design, including site planning, configuration, materials, construction, and operation where every aspect affected the house environmental performance. Nature has provide sufficient energy to tropical climate environment like Indonesia. Nevertheless, economically viable cluster housing is the other issue that encounter high costs housing from energy efficient building such as the Near Zero Energy House (nZEH) due to high price of materials and equipment used. The objective of the research is to understand how nZEH design parameter has been implemented and give impacts on architectural form of housing design. Methods used in this study is qualitative approach using research instruments among others: checklist, interview form and observation log book. From the case study conducted in this research, it was found that the object, the cluster design housing, are poorly incorporate the nZEH design parameter due to costly reasoning that impact to initial cost of the housing building. Among the design parameter which has been suggested are limited to passive design, fenestration, HVAC, lighting, and minor consideration to operation and maintenance.
Lean and sustainable construction: link between the sustainability report disclosure and the impact on profitable opportunities for investors
Authors: Kresnanto N C , Putri W H 
Published: October 2019

Abstract
Lean management in the construction sector is a company-driven movement to gain various advantages in running the business process. By implementing lean management, the company is simultaneously able to achieve multiple goals, such as profit maximization, while being able to eliminate non-value added activities and improve its environmental and social performance. To communicate these activities, the company issues a sustainability report, whose quality of disclosure depends on what the company has done with its business processes. This study tries to examine whether the quality of disclosures in sustainability reports has been able to contribute to influencing the number of earnings per share, which in this case is essential information for investors to see opportunities for profitability. The findings of this study indicate that, overall, disclosures in sustainability reports have not been a critical reference for investors, especially in looking at their profitability opportunities, and they only position this sustainability report as an additional source of information to ensure their concerns about social and environmental responsibility. The implication of this research for the development of sustainable construction is that it functions as a note to increase stakeholder engagement, especially investors, so that they appreciate the efforts of management to achieve competitive advantages and not only profit oriented.

Abstract
The purpose of this study was to determine whether the use of building function variables as dummy variables affected the duration of construction projects, together with identified measureable external factors. Multivariate regression is a technique that estimates a single regression model with more than one outcome variable. When there is more than one predictor variable in a multivariate regression model, the model is a multivariate multiple regression. Goodness of Fit (R2) of the equation regression analysist used as sensibility benchmarks. Variables are transformed to index number for unit synchronize. If the result is unsatisfied for predicting a project duration, an implementation of dummy variables could be tried if there any improvement of R2. The trial on this research, 43 data show that in first stage, five influence factors: Education Index, Technology Absorption Index, Labor Experience Index, New Technology Availability Index, and Innovation Index generate regression equation without full fill the mathematical requirement. At the second stage, by adding dummy variables based on type of building, apartment, office, hotel and other then the three type together with the five external factors, afford a good R2.

Published: October 2019

Abstract
Indonesia steel design code 2002 was revised in 2015. The latest version refers to AISC 360-10 which convert steel stability analysis to direct analysis method (DAM). DAM is an elastic analysis which includes second-order effect where P-delta and geometric imperfection are directly calculated during the analysis. Imperfection is modelled as notional load applied horizontally which is determined as 0.002 of gravity load. Numerical study using SAP software had been conducted to compare DAM and the previous method ELM on eccentrically braced frames (EBFs) under seismic load. It is known that EBF is one of earthquake resistant structural systems of steel structure. Numerical study was validated against experimental results performed by other researchers. Similar EBF frames used in the experiment were reanalyzed by ELM and DAM and coefficient of notional load is varied as 0.002 and 0.003. Seismic load applied in the analysis were varied based on three different seismic zones and soil conditions.

Published: October 2019

Abstract
This study studied the effect of using fiber on the shear strength of concrete beams without transverse reinforcement. The concrete mixture does not use coarse aggregate and uses stainless steel fiber with a diameter of 0.2 mm and a length of 36 mm. This study explains the effect of concrete quality on shear strength that can be carried by concrete beams with a ratio of 45 / 10.5, 25 / 10.5 and 20 / 10.5. The making of test specimens in this study was a beam of varying lengths of 110 cm, 70 cm and 60 cm while a width of 7 cm, and a height of 12.5 cm. From the test results, the shear stress value is calculated using the formula v / (b x d x √ (fc)) > 2 in international units, in which the shear capacity value is bigger than the code states. Diagonal tension failure occurs on 110cm beam and shear tension failure on 70 cm and 60 cm beams.

Abstract
This study discusses the results of the rapid assessment of school buildings in Lombok after an earthquake occurs. The earthquake in July 2018 with a high enough intensity caused a lot of damage to the building. The earthquake including the school building affected the entire area of Lombok Island. This study assessed 15 school buildings on Lombok Island. School samples were taken randomly from several districts that were rocked by the earthquake. The results showed that school buildings in all locations were part of a Non-Engineered Building where there were no results of analysis of earthquake resistant buildings. Overall, the condition of the building is categorized as being moderately damaged with non-structural components such as walls not having good connections with columns and beams. In addition, the structure and attributes of the roof are also damaged by a high percentage. In some buildings, it still does not follow good structural rules so that it is very dangerous for building users in the event of a large earthquake. Improvements using the retrofitting method are one of the most recommended ways to improve the performance of buildings that have mild and moderate damage.

Authors: Faizah R , Priyosulistyo H , Aminullah A 
Published: October 2019

Abstract
The accumulation of waste rubber tires causes environmental problems, due to most of them cannot be recycled into new tires. Recently, this waste is gradually used as a material replacement in civil engineering such as in increasing damping properties. This study investigates the physical and mechanical properties of waste rubber tires including density (ρ), ultimate tensile strength (σ), elongation at break, hardness (Shore A), modulus of elasticity (E), and shear modulus (G). The specimens used were coded as A, B, C, and D to represent specified brand name. The testing method referred to ISO standards and was carried out in the laboratory of Center for Leather, Rubber, and Plastics (CLRP), and the structural laboratory of Department of Civil Engineering and Environmental, Gadjah Mada University, Yogyakarta, Indonesia. The result shows that the density of all brands is nearly the same which is around 1.1 gr/cm3. The A rubber tire is indicated as the best damping properties since it has the lowest value on tensile strength, hardness, modulus of elasticity and shear modulus. However, the elongation at break is the highest value, compared to the other specimens. B rubber tire shows hard rubber, while C and D are high strength rubber. Therefore, B, C, and D rubber tires are appropriate to be used as barrier supports which must be able to withstand large forces, while the damping is not a priority.
A joint choice decision model of intra-household interaction-based motorcycle mode and departure time in Yogyakarta, Indonesia
Authors: Irawan Muhammad Zudhy 
Published: October 2019

Abstract
The motorcycle-based joint trip between family members in a household becomes a common phenomenon in responding to unreliable public transport. This study aims to model the joint choice decision between intra-household interaction-based joint trip using motorcycle and departure time. With the data collected from 416 workers using the motorcycles in Yogyakarta, Indonesia, a cross-nested logit model was developed to explore the individual and household characteristics, work-and travel-related characteristics influencing household-based joint trip and departure time. The model result reveals that motorcyclists are more likely to change their departure time rather than an intra-household-based joint trip. Motorcyclists departing on a peak hour have a lower elasticity due to the alteration of travel time and travel cost than motorcyclists leaving on an off-peak hour. In a case of the off-peak departure time, motorcyclists leaving home to work by driving alone are more elastic for a change of travel cost than motorcyclists departing to work with their family member.

Published: October 2019

Abstract
Solo-Yogyakarta KM 9-15 Road is the national highway, which supports the traffic of goods and services, but many passing goods transport vehicles do not match the allowable load. As a consequently, the damage on the pavement occurred. Therefore, this study aims was to know the effect of overloading on design life and pavement thickness. This study used the method of Binamarga to analyze the effect of pavement thickness caused by overloading. The analysis was carried out by using the formula of design life decreasing with the value of Cumulative Equivalent Standard Axle (CESA) for overloading and standard load. Based on the 2013 Binamarga method, the design life is reduced by about eight years, from the previously determined is 20 years. Moreover, based on the analysis on pavement thickness of 20 years design life for a standard load, it showed that pavement thickness is needed for total surface layer is 100 mm consist of AC WC 40 mm and AC BC 60 mm. In addition, the base course layer is 145 mm (AC Base), and the subbase course layer is 300 mm (LPA Kelas A). At the same time, for overloading, the analysis result showed that it was required the pavement thickness for the surface layer is 100 mm, the base course layer is 180 mm, and the subbase course layer is 300 mm. These results indicate that overloading causes a reduction in the design life of the pavement and an increase in the thickness of the pavement.
Computational analysis to study the effect of infusion of Tetracyanoquinodimethane in zinc based metal-organic framework

Published: October 2019

Abstract
The present study reports the computational analysis of band structures and density of state (DOS) profiles of a Tetracyanoquinodimethane (TCNQ) infused IRMOF-1 (Iso Reticular Metal-Organic Framework-1). IRMOF-1 is a zinc-based MOF and has been reported useful in literature for a variety of applications, including gas storage and sensing owing to its highly porous structure. We have adopted a SIESTA based computational investigation approach to investigate the tuning of the band structure and DOS of IRMOF-1 via the infusion of a redox active species, i.e., TCNQ. The results have highlighted that the doping of TCNQ in IRMOF-1 is useful for the realization of a novel material with an estimated band gap of 4.35 eV. The necessary computational steps involved various optimization steps, such as the optimization of mesh-cutoff, lattice constant, lattice volume, and conjugate gradient. These computation studies have thus established that an approach of doping IRMOF-1 with TCNQ can result in the development of a suitably functional porous material that can be further exploited as an ultrawide‐bandgap semiconductor material or for the electrochemical sensing of different analytes, such as gases.
Strongly anisotropic type II blow up at an isolated point

Published: October 2019

We consider the energy supercriticald+1d+1-dimensional semi-linear heat equation∂tu=Δu+up, x∈Rd+1, p≥3, d≥14.\begin{equation*} \partial _tu=\Delta u+u^{p}, \ \ x\in \Bbb R^{d+1}, \ \ p\geq 3, \ d\geq 14. \end{equation*}A fundamental open problem on this canonical nonlinear model is to understand the possible blow-up profiles appearing after renormalisation of a singularity. We exhibit in this paper a new scenario corresponding to the first example of a strongly anisotropic blow-up bubble: the solution displays a completely different behaviour depending on the considered direction in space. A fundamental step of the analysis is to solve thereconnection problemin order to produce finite energy solutions which is the heart of the matter. The corresponding anistropic mechanism is expected to be of fundamental importance in other settings in particular in fluid mechanics. The proof relies on a new functional framework for the construction and stabilisation of type II bubbles in the parabolic setting using energy estimates only, and allows us to exhibit new unexpected blow-up speeds.
