Authors: Sanjaya Z N , Utomo A B 
Published: February 2022

Abstract
Physical distancing is one of the procedures to avoid the spread of Covid-19. Several researchers have created tools to support physical distancing and the detection focus is on the front or back side with sound alert. However, this kind of sound alert can disturb other people activities. Moreover, people have a blind spot in their right and left side vision which is more than 400 on the horizontal plane. The study aims to design two bracelets for socializing in physical distancing during Covid-19 pandemic. It works at a distance of 1 meter within a radius of 1200 on eye blind spot and provide the option of a vibration or sound alert or both with the push button. The main components of this tool are Arduino nano as the system controller, HC-SR 04 ultrasonic sensor as the distance measure, PIR HC-SR 501 sensor as the people movement detection, continuous rotation servo motor MG90S as the sensors driver of 1200, vibrating DC motor type 310-101 as the vibration output and buzzer as the sound output. The result of this study is two bracelets that available to detect distance and movement on the 1200 rotation angle. When both of bracelets on the 1-meter distance, they will make vibration, sound, or both.

Authors: Setiawan M F 
Published: February 2022

Abstract
Thermal comfort is a person’s state of mind that expresses a person’s level of satisfaction with his environment. Optimal thermal comfort can be achieved by considering several factors, including building orientation, air conditioning, position and size of openings, building materials, and others. The purpose of this study is to find recommendations for designing thermal comfort in cities on the island of Java using Mahoney Tables. Mahoney Tables is a collection of reference tables used in construction as climate-friendly design references. In this study, climate and meteorological data will be taken in certain cities on the island of Java. From the results of the above discussion, it can be concluded that the building must pay attention to 4 aspects, namely openings, the building must have wide openings located on the south-north side of the building and the openings must be as high as the human body; The room must be one room without a partition; Building envelopes, buildings must be protected from direct sunlight and rain by paying attention to the selection of materials; and building utilities must pay attention to drainage. The recommendations above are expected to be used by architects/researchers who will design/research buildings to be comfortable.

Published: February 2022

Abstract
Construction has been significantly influenced by COVID-19. In some countries, construction projects are discontinued, and even in some countries where construction work is still permitted, high safety standards are required. Construction site safety is essential during the COVID-19 pandemic. The contractor is responsible for creating a safe workplace at the project site. Therefore, this paper presents project risk identification and mitigation during the covid-19 pandemic based on contractor’s perspective. This research identified the risk factors related to the COVID-19 pandemic that consist of 5 categories: man, materials, machines, methods, and environment. Between these risk factors, worker shortage, site accessibility, and lack of construction materials, caused by the strict large-scale social restrictions (PSBB) policy are the biggest challenges faced by the contractor. The findings of this research develop the project risk categories and mitigation strategies from the contractor’s perspective. It suggests that future construction in addition to planning the design, operate, maintenance, supply chain, and project management must also consider the occurrence of a pandemic.

Published: February 2022

Abstract
Technological innovation provides many business opportunities (technopreneurs) that involve various fields of study. Architecture is not an exception; technological advances can create a “hi-tech” masterpiece. There are two fields of study related to the application of architectural technology. First, the use of technology to improve the quality of architectural products, so that the design results are considered to be able to keep up with the times, such as materials and technological elements. Second, a form of architectural preservation that can be used as a guide in following technological developments, such as spatial planning. During the Diponegoro War some of his followers were forced to leave Mataram, then those who stopped in Pekalongan began to introduce batik in three areas: Wonopinggo, Pekajangan, and Buaran in 1825-1830. Gradually, batik production increased, until it is expanded into weaving craft. Both types of clothing production can’t be separated from technological advances, handmade batik is replaced with stamped batik, and the weaving of ATBM production changes to using ATMs. The historical journey that transformed Pekalongan as a well-known clothing city in Indonesia is interesting to study, especially in the architectural field, namely spatial planning formed from local culture. This study discusses the spatial preservation of clothing production houses in three areas in Pekalongan, namely: Pekajangan, Kauman, and Pesindon. The objective of the study was to identify the form of spatial preservation used during the development of clothing-making technology. Descriptive-exploratory research method is used to explore elements of local wisdom used as guidelines for spatial planning. The results of the study elaborate that the layout of the clothing production house in Pekajangan, Kauman, and Pesindon consists of: living room, family room, drying room, and factory. However, there are differences in the location of the drying room. This difference is due to the change in function from residential building to production building, and also from the development of clothing technology. This requires some additional spaces. Based on the research results from the three areas, the factory is a long-lasting and sustainable space category.
Youth social behaviour in using the city’s public space (case study of Menteng Bintaro park)
Authors: Purnomo A 
Published: February 2022

Abstract
The Menteng Bintaro park is one of the city parks available in South Tangerang City. This city park is one of the destinations frequently visited by the community, especially teenagers. Social behaviour commonly owned by adolescents is usually characterized by the tendency of adolescents to try to separate themselves from parental supervision where adolescents tend to have a desire to be free, but not infrequently adolescent behaviour leads to deviant behaviour patterns. As a public facility, a city park must of course provide comfort for everyone who visits it. So, it is necessary to make observations about the social behaviour of adolescents in using city parks as public spaces. This research objective was to evaluate the social behaviour of adolescents in using urban public spaces with details including: identifying forms of adolescent social behaviour in utilizing city parks; evaluating the existing condition of the city park; identify the factors that influence the use of Menteng Bintaro park by youth. The object of research is Menteng Bintaro Park which is located in Sector 7 Bintaro Jaya, Jl. Wahid Hasyim, Pondok Jaya, Kecamatan Pondok Aren, South Tangerang City, Banten. This study uses descriptive qualitative methods with data collection techniques including observation and documentation. The data analysis technique used in this research is descriptive qualitative.

Published: February 2022

Abstract
The paper presents an investigation of university students’ travel mode choice behaviour for commuting to campus. It uses a dataset collected through a survey among students of four universities in Semarang, i.e., Unnes, UINW, Udinus, and Unissula. Eight hundred and thirty-seven respondents completed the questionnaires. Multinomial logit (MNL) models are used for investigating four transport mode choices, i.e., walk, motorcycle, car, and bus. The independent variables are schools, genders, origin, residential types, vehicle ownership, driving license ownership, monthly allowance, transportation budget, and commuting distance. The model shows that all independent variables, except monthly allowance, are significant predictors. Overall, the model prediction accuracy is about 90 percent. A motorcycle was the foremost prevalent transport for school trips. Empirical models reveal that the mode of choice behaviour of non-native students differs significantly from those that originate in Semarang. The log odds of driving a car, riding a motorcycle, and walking versus riding a bus are higher when students’ origin is not from Semarang compared to Semarang.

Abstract
One of the anchor functions is to connect the construction steel joint to the concrete to transfer the tensile force of steel to concrete. The research aimed to compare the theoretical and experimental adhesive stress and the pullout capacity of plain steel single anchors and deformed cast in place and retrofit post-installed chemical epoxy sika anchor fix-2. The experimental result of the cast in place method of the plain steel anchors to the theoretical increase by 3.657% and deformed steel anchor increased by 50.13%; retrofit post-installed chemical epoxy sika anchor fix-2 method of plain steel to the theoretical increased by 23.29% and deformed steel anchor increased 63.69% and plain steel anchor method and retrofit postinstalled chemical epoxy sika anchor fix-2 to the cast in place increased by 18.404% and steel anchor deform increased by 8.905%. Therefore, retrofit post-installed chemical epoxy sika anchor fix-2 plain anchor and deformed steel anchor give better results than cast in place theory so that the basis for the planning can be used as the basis for retrofit post-installed chemical epoxy sika anchor fix-2 while overall, deformed steel anchor is still better than plain steel anchor.

Authors: Nugroho U , Falah K T 
Published: February 2022

Abstract
The growth of vehicles in the city of Semarang is fast, as calculated based on the BPS Semarang the number of vehicle growth is 11% per year. This causes the road capacity to be periodically increased. As is the case at the adjacent intersections on Dewi Sartika street and Talangsari street initially, to break up delays and queues and increase capacity, efforts were made to add a 7-meter-wide bridge. However, this widening will not solve the problem in the next 5 years so that alternative solutions are needed for the two intersections. This study aims to evaluate the two intersections using the Binamarga method based on the 1993 MKJI, to determine the capacity of the intersection and plan the design of the intersection in the future and then make modelling with PTV Vissim Software to describe the simulation of the actual situation.
The role of asymmetry in few-cycle, mid-IR pulses during THz pulse generation
Authors: Flender Roland , Borzsonyi Adam , Chikan Viktor 
Published: February 2022

Abstract
The efficiency of terahertz (THz) pulse generation improves at longer driving wavelengths. For this reason, the use of mid-infrared (MIR) sources is more advantageous compared to visible or near-infrared systems. In this work, we investigate how single-color and two-color schemes of MIR pulses with few-cycle pulse durations compare in producing THz pulses. The results reveal that as the duration of the driving pulses decreases, the second harmonic generation crystal can be omitted from the system. Our numerical study pinpointed three regions where the optimal pulse parameters are fundamentally different for the most efficient THz pulse generation. The first is the two-color approach, where the two-color scheme is dominant at 3.2 optical cycles and over. The second is the single-color approach, where the single-color scheme becomes dominant at 1.7 optical cycles and below. Therefore, it simplifies the traditional two-color scheme for THz pulse generation. There is also a third transitional region where the two-color scheme still prevails, but the sign of the relative phase between the input pulses becomes important. Considering the effect of the relative phase and the carrier to envelope phase (CEP) effect on the THz pulse generation, the results have shown that as the pulse duration become shorter, the role of the CEP becomes important for efficient THz generation. By measuring the efficiency of the THz generation in this optical arrangement, quantifying the CEP becomes possible, which could become an important experimental tool for few-cycle, MIR laser technology.

Abstract
Mung bean (Vigna radiata) sprouts are widely consumed worldwide due to their high nutritional value. However, the low yield and microbial contamination of mung bean sprouts seriously reduces their economic value. This study investigates the effects of non-thermal plasma on the quality and microbial reduction of mung bean sprouts by pretreatment of seeds in water for different times (0, 1, 3 and 6 min). The quality results showed that short-time plasma treatment (1 and 3 min) promoted seed germination and seedling growth, whereas long-time plasma treatment (6 min) had inhibitory effects. Plasma also had a similar dose effects on the total flavonoid and phenolic contents of mung bean sprouts. The microbiological results showed that plasma treatment achieved a reduction of native microorganisms ranging from 0.54 to 7.09 log for fungi and 0.29 to 6.80 log for bacteria at 96 h incubation. Meanwhile, plasma treatment could also efficiently inactivate artificially inoculated Salmonella typhimurium (1.83–6.22 log) and yeast (0.53–3.19 log) on mung bean seeds. The results of seed coat permeability tests and scanning electron microscopy showed that plasma could damage the seed coat structure, consequently increasing the electrical conductivity of mung bean seeds. The physicochemical analysis of plasma-treated water showed that plasma generated various long- and short-lived active species [nitric oxide radicals (NO·), hydroxyl radicals (·OH), singlet oxygen (1O2), hydrogen peroxide (H2O2), nitrate (

on bacterial inactivation and plant growth promotion. Taken together, these results imply that plasma pretreatment of mung bean seeds in water with moderate oxidizability and acidity is an effective method to improve the yield of mung bean sprouts and reduce microbial contamination.

A doubling of atmospheric CO2 mitigates the effects of severe drought on maize through the preservation of soil water
Authors: Ripley B S , Bopape T M , Vetter S 
Published: February 2022

Abstract

Background and Aims
Drought limits maize production in many regions of the world, and this is likely to intensify in future. Elevated atmospheric CO2 (eCO2) can mitigate this by reducing stomatal conductance and water loss without reducing yield. The magnitude of this effect depends on the interaction of eCO2 and drought severity, but scarce data collected under severe drought conditions limit predictions of future maize production.

Methods
We compared the severe drought × eCO2 responses of six maize genotypes from semi-arid and sub-humid growing regions.

Key Results
Genotypic differences were apparent in growth, gas exchange, water relations, grain quality, and biomass at maturity, but the response to eCO2 was consistent. Plants under drought and eCO2 had similar biomass and yield to irrigated plants at ambient CO2. Reduced stomatal conductance and water loss preserved soil moisture equivalent to 35 mm of rainfall and allowed sustained photosynthesis at higher rates for a longer period after watering stopped. Under irrigation, eCO2 improved maize growth but not grain yield.

Conclusions
The results suggest that eCO2 may extend the future land area available to rainfed maize cultivation, but cannot circumvent the absence of seasonal rainfall that restricts maize growth. Elevated CO2 will reduce water requirements of irrigated maize when atmospheric conditions drive high evapotranspiration.
Multiview network embedding for drug-target Interactions prediction by consistent and complementary information preserving
Authors: Shang Yifan , Ye Xiucai , Futamura Yasunori , Yu Liang , Sakurai Tetsuya 
Published: February 2022

Abstract
Accurate prediction of drug-target interactions (DTIs) can reduce the cost and time of drug repositioning and drug discovery. Many current methods integrate information from multiple data sources of drug and target to improve DTIs prediction accuracy. However, these methods do not consider the complex relationship between different data sources. In this study, we propose a novel computational framework, called MccDTI, to predict the potential DTIs by multiview network embedding, which can integrate the heterogenous information of drug and target. MccDTI learns high-quality low-dimensional representations of drug and target by preserving the consistent and complementary information between multiview networks. Then MccDTI adopts matrix completion scheme for DTIs prediction based on drug and target representations. Experimental results on two datasets show that the prediction accuracy of MccDTI outperforms four state-of-the-art methods for DTIs prediction. Moreover, literature verification for DTIs prediction shows that MccDTI can predict the reliable potential DTIs. These results indicate that MccDTI can provide a powerful tool to predict new DTIs and accelerate drug discovery.

RF-Net 2: fast inference of virus reassortment and hybridization networks
Authors: Markin Alexey , Wagle Sanket , Anderson Tavis K , Eulenstein Oliver 
Published: February 2022

Abstract

Motivation
A phylogenetic network is a powerful model to represent entangled evolutionary histories with both divergent (speciation) and convergent (e.g. hybridization, reassortment, recombination) evolution. The standard approach to inference of hybridization networks is to (i) reconstruct rooted gene trees and (ii) leverage gene tree discordance for network inference. Recently, we introduced a method called RF-Net for accurate inference of virus reassortment and hybridization networks from input gene trees in the presence of errors commonly found in phylogenetic trees. While RF-Net demonstrated the ability to accurately infer networks with up to four reticulations from erroneous input gene trees, its application was limited by the number of reticulations it could handle in a reasonable amount of time. This limitation is particularly restrictive in the inference of the evolutionary history of segmented RNA viruses such as influenza A virus (IAV), where reassortment is one of the major mechanisms shaping the evolution of these pathogens.

Results
Here, we expand the functionality of RF-Net that makes it significantly more applicable in practice. Crucially, we introduce a fast extension to RF-Net, called Fast-RF-Net, that can handle large numbers of reticulations without sacrificing accuracy. In addition, we develop automatic stopping criteria to select the appropriate number of reticulations heuristically and implement a feature for RF-Net to output error-corrected input gene trees. We then conduct a comprehensive study of the original method and its novel extensions and confirm their efficacy in practice using extensive simulation and empirical IAV evolutionary analyses.
