Context. The properties of the population of Galactic supernova remnants (SNRs) are essential to our understanding of the dynamics of the interstellar medium (ISM) in the Milky Way. However, the completeness of the catalog of Galactic SNRs is expected to be only ~30%, with on order 700 SNRs yet to be detected. Deep interferometric radio continuum surveys of the Galactic plane help in rectifying this apparent deficiency by identifying low surface brightness SNRs and compact SNRs that have not been detected in previous surveys. However, SNRs are routinely confused with H II regions, which can have similar radio morphologies. Radio spectral index, polarization, and emission at mid-infrared (MIR) wavelengths can help distinguish between SNRs and H II regions.

Aims. We aim to identify SNR candidates using continuum images from the Karl G. Jansky Very Large Array GLObal view of the STAR formation in the Milky Way (GLOSTAR) survey.

Methods. GLOSTAR is a C-band (4–8 GHz) radio wavelength survey of the Galactic plane covering 358° ≤ l ≤ 60°, |b|≤ 1°. The continuum images from this survey, which resulted from observations with the most compact configuration of the array, have an angular resolution of 18″. We searched for SNRs in these images to identify known SNRs, previously identified SNR candidates, and new SNR candidates. We study these objects in MIR surveys and the GLOSTAR polarization data to classify their emission as thermal or nonthermal.

Results. We identify 157 SNR candidates, of which 80 are new. Polarization measurements provide evidence of nonthermal emission from nine of these candidates. We find that two previously identified candidates are filaments. We also detect emission from 91 of the 94 known SNRs in the survey region. Four of these are reclassified as H II regions following detection in MIR surveys.

Conclusions. The better sensitivity and resolution of the GLOSTAR data have led to the identification of 157 SNR candidates, along with the reclassification of several misidentified objects. We show that the polarization measurements can identify nonthermal emission, despite the diffuse Galactic synchrotron emission. These results underscore the importance of higher resolution and higher sensitivity radio continuum data in identifying and confirming SNRs.

Published: April 2021

The Apollo 15 and 16 missions were the first to explore the Lunar surface chemistry by investigating about 10% of the Lunar surface using a remote sensing X-ray fluorescence spectrometer experiment. The data obtained have been extensively used to study Lunar formation history and geological evolution. In this work, a re-evaluation of the Apollo 15 and 16 X-ray fluorescence experiment is conducted with the aim of obtaining up-to-date empirical values for aluminum (Al) and magnesium (Mg) concentrations relative to silicon (Si) of the upper Lunar surface. An updated instrument response, a newly reconstructed Lunar trajectory orbit, and improved intensity ratio calculations were used to obtain new intensity ratio maps. The resulting Lunar Al/Si and Mg/Al X-ray maps show a clear distinction in Lunar mare and highland regions. The mean Al/Si and Mg/Al intensity ratios for the mare regions obtained from the newly obtained maps are 0.54 ± 0.07 and 0.54 ± 0.17, respectively; for the highland regions, the values are 0.76 ± 0.07 and 1.07 ± 0.13, respectively. For the Mg/Si intensity ratio, no clear distinction between Lunar features is obtained and we derived a mean value of 0.47 ± 0.13. Our determined intensity ratios are lower than previously published. These values can be used to infer concentration ratios when accounting for Solar activity, inter-orbit variability, and measurements from different instruments. We employed a correction to infer concentration ratios by comparing our intensity ratios directly to Lunar rock concentrations obtained from various Lunar missions.

Die Symptomatik des thorakalen Bandscheibenvorfalls ist außerordentlich variabel und bereitet nicht selten differenzialdiagnostische Schwierigkeiten. An diese Ursache für die Beschwerden überhaupt zu denken, ist der der wichtigste diagnostische Schritt. Das MRT erbringt dann die endgültige Diagnose. Bei primär radikulären Beschwerden oder leichten Dorsalgien
ohne neurologische Ausfälle ist zunächst eine konservative Therapie zu empfehlen.

Ein operatives Vorgehen ist nur beim symptomatischen Patienten indiziert. Die operative Massnahme sollte die ventral lokalisierte Pathologie sicher erreichen und möglichst visualisieren können.

Published: April 2021

Ziel der Studie Ziel dieser Studie war es, die Empfehlungen eines etablierten ABS-Teams während der wöchentlichen Routinevisiten zu evaluieren sowie ihre Umsetzungsrate und die Gründe der Nichtumsetzung zu untersuchen.

Methodik Die Visiten eines multiprofessionellen ABS-Teams (Infektiologie, Mikrobiologie, Apotheke und Krankenhaushygiene) wurden über 8 Wochen auf 9 intensivmedizinischen und peripheren Stationen eines Universitätsklinikums (1451 Betten) begleitet. Die Empfehlungen des ABS-Teams wurden prospektiv analysiert und bei fehlender Umsetzung Gründe standardisiert von den behandelnden Ärzten erfragt.

Ergebnisse Während des Beobachtungszeitraums fanden bei 262 Patienten 359 ABS-Visiten statt. Im Median nahmen 4 Ärzte und 1 Apotheker (Q25/Q75: 4/6) an den ABS-Visiten teil. Bei 177/359 (49%) ABS-Visiten erfolgte mindestens eine Empfehlung zur Antiinfektivatherapie. Insgesamt wurden 210 Empfehlungen ausgesprochen. Am häufigsten waren mit 38% (80/210) Empfehlungen zur Einhaltung der festgesetzten Therapiedauer. Je mehr unterschiedliche Berufsgruppen an der ABS-Visite teilnahmen, je eher wurde eine Empfehlung ausgesprochen (p=0,016; Odds Ratio=1,018 (1,003–1,033)). 62/210 (30%) der Empfehlungen des ABS-Teams wurden vom behandelnden Arzt nicht umgesetzt. Als häufigster Grund wurde mit 32% (20/62) eine bewusst von der Empfehlung abweichende Therapieentscheidung angegeben.

Schlussfolgerung Die hohe Empfehlungsrate von knapp 50% zeigt den Bedarf an Therapieoptimierung durch ABS-Teams in der Routine. Je multiprofessioneller diese besetzt sind, desto häufiger werden auch Empfehlungen ausgesprochen. Gründe für die fehlende Umsetzung von Empfehlungen sollten kritisch hinterfragt werden – sowohl seitens des ABS-Teams als auch seitens der behandelnden Ärzte auf Station.

Published: April 2021

Protein detection and quantification is a routinely performed procedure in research laboratories, predominantly executed either by spectroscopy-based measurements, such as NanoDrop, or by colorimetric assays. The detection limits of such assays, however, are limited to μM concentrations. To establish an approach that achieves general protein detection at an enhanced sensitivity and without necessitating the requirement for signal amplification steps or a multicomponent detection system, here, we established a chemiluminescence-based protein detection assay. Our assay specifically targeted primary amines in proteins, which permitted characterization of any protein sample and, moreover, its latent nature eliminated the requirement for washing steps providing a simple route to implementation. Additionally, the use of a chemiluminescence-based readout ensured that the assay could be operated in an excitation source-free manner, which did not only permit an enhanced sensitivity due to a reduced background signal but also allowed for the use of a very simple optical setup comprising only an objective and a detection element. Using this assay, we demonstrated quantitative protein detection over a concentration range of five orders of magnitude and down to a high sensitivity of 10pgmL−1, corresponding to pM concentrations. The capability of the platform presented here to achieve a high detection sensitivity without the requirement for a multistep operation or a multicomponent optical system sets the basis for a simple yet universal and sensitive protein detection strategy.

Published: April 2021

Environmental context The ocean-produced dimethyl sulfide (DMS) molecule is thought to affect cloud formation and the solar radiation budget at the Earth’s surface, hence playing an important role in regulating climate. In this study, we calculated the DMS sea-to-air flux across the Southern Ocean, south-east Indian Ocean and north-west Pacific Ocean, and analysed the influence of DMS fluxes on sulfate aerosols. These results improved our understanding of the effects of DMS emissions on sulfate compounds in the atmosphere over the global ocean. Abstract Oceanic dimethyl sulfide (DMS) is the most abundant biogenic sulfur compound emitted into the atmosphere and could indirectly regulate the global climate by impacting end product sulfate aerosols. DMS emissions and their influence on sulfate aerosols, i.e. methanesulfonic acid (MSA) and non-sea-salt sulfate (nss-SO42–), were investigated over the Atlantic Ocean and Indian Ocean sectors of the Southern Ocean (SO), the south-east Indian Ocean, and the north-west Pacific Ocean from February to April 2014 during the 30th Chinese National Antarctic Research Expedition. We found a strong large-scale DMS source in the marginal sea ice zone from 34 °W to 14 °E of the SO (south of 60 °S), in which the mean flux was 49.0 ± 65.6 μmol m−2 d−1 (0.6–308.3 μmol m−2 d−1, n = 424). We also found a second large-scale DMS source in the South Subtropical Front (~40 °S, up to 50.8 μmol m−2 d−1). An inconsistency between concentrations of atmospheric sulfate compounds and DMS emissions along the cruise track was observed. The horizontal advection of air masses was likely the main reason for this discrepancy. Finally, the biological exposure calculation results also indicated that it is very difficult to observe a straightforward relationship between oceanic biomass and atmospheric MSA.

Iris yellow spot virus (Iris yellow spot).
Authors:   CRCNPB
Published: April 2021

In 1981, de Avila et al. (1981) described a disease characterized by chlorotic and necrotic, eye-like or diamond-shaped lesions on onion scapes (referred to as 'sapeca') in southern Brazil. In 1989, Hall et al. (1993) observed a very similar disease in onion in the USA and detected a tospovirus, which was later shown by Moyer et al. (1993) to be Iris yellow spot virus on the basis of molecular and serological data. In 1998, a new tospovirus was isolated and characterized in the Netherlands from infected iris and leek and named Iris yellow spot virus (IYSV) (Cortês et al., 1998). This virus was subsequently found naturally infecting onion in several major onion-producing states of the USA and around the world (for reviews, see Gent et al., 2006 and Pappu et al., 2009). Gera et al. (1998b) reported that IYSV was responsible for a 'straw bleaching' disease on onion in Israel. In 1999, a 'sapeca' isolate from Brazil was identified as IYSV on the basis of biological, serological and molecular data (Pozzer et al., 1999). In Israel, Kritzman et al. (2000) reported natural IYSV infection of lisianthus grown in the field. IYSV has now been endemic in south-western Idaho and eastern Oregon in onion, leek and chive seed production fields for over 10 years. Losses caused by IYSV can reach 100% in onion crops, for example, in Brazil (Pappu et al., 2009). However, studies in the Netherlands in 2008 showed that latent infections of IYSV were common in onion crops but did not cause economic damage (NPPO of the Netherlands, 2008). Iris yellow spot represents an immediate and serious threat to sustainable and productive onion cropping systems around the world, and the recent detection of this disease in numerous onion-producing countries demonstrates that the disease is spreading rapidly in a range of environments. IYSV is on the EPPO Alert list (http://www.eppo.org/QUARANTINE/Alert_List/alert_list.htm).
Influence of temperature on terahertz waves propagating in magnetized plasma

Published: April 2021

The transmission characteristics, including reflectivity, transmissivity and absorptivity, of terahertz waves propagating in high temperature magnetized plasmas are studied numerically and theoretically. The numerical results indicate that the transmission characteristics will be influenced by the wave frequency, electron temperature, plasma density, collision frequency, thickness of plasma and the external magnetic field. It is found that the strength of magnetic field distinctly affects the transmissivity trough and absorptivity peak when terahertz waves penetrate in the plasma. When the electron temperature is higher than 10 keV, the influence of temperature can be observed obviously. These results maybe provide a significative theoretical basis to a certain extent, for the ‘blackout’ communication.
Optical solitons for the decoupled nonlinear Schrödinger equation using Jacobi elliptic approach
Authors: Sabi’u Jamilu , Tala-Tebue Eric , Rezazadeh Hadi , Arshed Saima , Bekir Ahmet
Published: April 2021

Most of the important aspects of soliton propagation through optical fibers for transcontinental and transoceanic long distances can best be described using the nonlinear Schrödinger equation. Optical solitons are electromagnetic waves that span in nonlinear dispersive media and permit the stress and intensity to stay unaltered as a result of the delicate balance between dispersion and nonlinearity effects. However, this study exploited the Jacobi elliptic method and obtained different soliton solutions of the decoupled nonlinear Schrödinger equation with ease. Discussions about the obtained solutions were made with the aid of some 3D graphs.
Collective motion of polar active particles on a sphere*

Published: April 2021

Collective motion of active particles with polar alignment is investigated on a sphere. We discussed the factors that affect particle swarm motion and define an order parameter that can show the degree of particle swarm motion. In the model, we added a polar alignment strength, along with Gaussian curvature, affecting particles swarm motion. We find that when the force exceeds a certain limit, the order parameter will decrease with the increase of the force. Combined with our definition of order parameter and observation of the model, the reason is that particles begin to move side by side under the influence of polar forces. In addition, the effects of velocity, rotational diffusion coefficient, and packing fraction on particle swarm motion are discussed. It is found that the rotational diffusion coefficient and the packing fraction have a great influence on the clustering motion of particles, while the velocity has little influence on the clustering motion of particles.

Published: April 2021

Thermal comfort is a comfort that relates to the room’s temperature conditions such as heat and cold which is manifested from the sensor on the skin and conveyed to the brain. So, the body can adjust the temperature to the surrounding environment. According to the American Standard of ASHRAE 55 of 2009, The purpose of this study is to analyze the suitability of the thermal comfort standard at the At-Taqwa Mosque of the GegerKalong KPAD. The research is conducted by measuring the thermal comfort at the At-Taqwa Mosque. It uses an anemometer measurement tool. The aspects of thermal comfort measured are wind speed, temperature, and relative humidity. The measurement results show that the thermal comfort at the At-Taqwa Mosque is still below the standard. The results of this measurement are simulated on three digital software which are named Sunhour, Flowdesign, and CBE Thermal Comfort. The results of the simulations on these three software show the thermal comfort at the At-Taqwa Mosque doesn’t approve to standard of ASHRAE 55 of 2009 because the highest temperature is on the western exterior area with 33.5 C and the lowest is on the eastern interior area with 23.6 C.
The Influence of the Sound Absorber Application to the Acoustics Conditions and the Thermal Transfer Value of the Building Envelope in Open Plan Office

Published: April 2021

In open plan office concept, the acoustical distraction problems have become a common problem. Besides, it also needs to deal with thermal issues to have a comfortable work environment. Since the concern of sustainable design is highly discussed, design solutions need to consider energy-saving and environmental health. Commonly sound absorber materials are used to improve acoustics quality. To increase the absorptance, the absorber is installed with air gap and filled with additional insulation e.g. mineral wool. These extra layers potentially give benefit to reduce the thermal transfer when being applied on the envelope walls and ceilings. It is because some of the sound absorber material, air gap, and mineral wool have a low thermal conductivity resulting in lower thermal transfer. This research observes the influences of various sound absorber applications on the acoustics condition and also the impact on the overall thermal transfer value (OTTV and RTTV). The thermal transfer calculation refers to Indonesia National Standard SNI-03-6389-2000, while the rooms acoustics is simulated with Software CATT Acoustics v9 referring to BS EN ISO 3382-3:2012. Absorber materials that been involved are wood wool and PET panel. The result shows that wood wool that applied with 30 mm air gap and additional insulation have reduced the OTTV and RTTV of the room envelope. The initial room condition with Reverberation Time 3.71 second has been reduced to 0.48 second, while OTTV and RTTV are reduced from 48.65 W/m2 and 37.38 W/m2 become 44.24 W/m2 and 14.27 W/m2 respectively.

Published: April 2021

One of the efforts to decrease environmental impact due to construction activities is by reducing Embodied Energy in design phase. In the design phase, EE can be associated with the usage of construction materials. On the other hand, the Building Information Modeling (BIM) can be an alternative approach in improving the effectiveness and efficiency material usage. The aim of this paper is to explain how to implement BIM in calculating and reducing the value of EE. The research methodology is a mix qualitative-quantitative method that conducted by using a case study and utilized BIM model of low-cost public apartment. The EE calculation is based on material properties of the BIM model and it also depends on the unit price analysis of each construction works. Furthermore, the Life Cycle Analysis (LCA) method is used to calculate the EE of materials properties value. In order to find the best EE reduction value, a comparison analysis is conducted that it compared the use of conventional materials (as alternative 1) and 2 types of substitution materials there are prefabricated wall panels and concrete masonry unit. Thus, the EE reduction value can be seen and the best low EE material will be used as a reference in the next phase of the construction process.

Published: April 2021

Compulsory education is one of the Indonesian government’s programs in an effort to advance the nation. The compulsory education program can run well if it is supported by right facilities and infrastructure, such as good quality educational buildings. The technical performance of educational buildings can be realized with good quality if the building is designed and built with due observance to the technical standards of a predetermined building. With the same quality of educational buildings in all regions of Indonesia, this study will evaluate the technical performance standards of basic education buildings. The aim of the study was to determine the feasibility level of the technical performance of basic education buildings in Indonesia based on the UNESCO guidelines for school building design in Asia. The study used a qualitative method with a comparative case study approach, namely six basic education buildings in the province of Bali. Those buildings are compared with UNESCO guidelines based on aspects of the environment, teaching spaces and service areas.The results of this comparison are expected to be able to consider more environmental aspects, teaching spaces and service areas in sustainable design, development and maintenance so that the policies applied are localities, such as the use of materials and building methods
Modularity in Design for Disassembly (DfD): Exploring the Strategy for a Better Sustainable Architecture
Authors: Arisya Khalda Fadhilah , Suryantini Rini
Published: April 2021

This paper explores the idea of modularity as one of the important design strategies that potentially creates a circular and more sustainable architecture. Modularity is a common design strategy used to generate form, create spatial efficiency, support mass production and prefabricated design, particularly in modern architecture. However, its contribution to sustainability is rarely discussed. This paper utilises Design for Disassembly (DfD) as a framework to investigate the potential of modularity in design, speculating that such design aspects can potentially minimize waste and improve efficiency in the systematic assembly and disassembly of building components. This paper employs two architectural projects designed with DfD approach as study cases, the Loblolly House and Cellophane House in the USA. The data are taken from works of literature and online secondary sources. The particular building components are mapped based on categories, such as building layers or joints and analysed based on its modular characteristics. The study reveals that the application of modules in particular building layers and separable joints with further use of the division-subdivision operation are significant design strategies found in each case. Such strategies provide better flexibility and interchangeability of building components during the assembly-disassembly process, proven by the calculation of construction waste. These findings arguably expand the discussion of modularity and encourage further study of modular design for a better sustainable architecture.

The need for light in the room is something that cannot be negotiated. Meeting these needs can be obtained through natural lighting and artificial lighting or a combination of both. The purpose of this study is to analyze the performance of natural lighting, especially the daylight factor in the Hall of the Faculty of Engineering, State University of Gorontalo, and provide solutions to improve lighting performance in the room. The research method was carried out through a computer simulation (computer simulation) with DIALux Evo 9.0 software by comparing the existing model and the engineering design model. The latter was carried out by changing the handrail material into transparent material such as glass, adding windows on both sides, and adding light shelves outside and inside the building. The FT Hall room simulation was conducted on September 21 with clear sky conditions within the significant lecture period from 07.00 to 17.00. The simulation results show that the engineering design can increase natural light intensity on the left and right edges compared to the existing conditions, with an average increase of 18%. However, this engineering has not reached the middle of the stands, so that additional engineering is needed to optimize natural lighting. Interestingly, this engineering design reduced excessive light intensity at points A1 and A3 with an average of 847 lux at the existing A1 point, down to 709 lux in the engineering design. Meanwhile, A3, with an average of 653 lux for the existing one, drops to 569 lux in the engineering design. The result shows that the engineering design can optimize the direction of light according to the target point and reduce glare, although additional engineering is still needed.
Thermal performance of reused shipping containers as building components

Published: April 2021

The era of disruption occurred influenced by innovations that emerged according to the needs and developments of the times. This occurs in various sectors, including the construction industry sector. One of the growing innovations in the construction industry sector is the reuse of shipping containers (SC) into buildings with various functions. The trend of reusing SC as buildings is quite significant. Several sectors have used a lot of SC as buildings, including: Offices, educational, commercial and residential. However, the reuse of SC as a building has several weaknesses, one of which is the thermal aspect. The structure of the container, which is generally composed of steel, should be considered in achieving indoor thermal comfort. The case study of the paper was SC buildings at Institut Teknologi Sains Bandung (ITSB). The aims of this study were to determine the contribution of design parameters of SC to indoor thermal comfort and its effect on energy efficiency. The method was model simulation on the thermal aspect using Sefaira software. The results showed that setting of design parameters considerably contributed to thermal comfort and energy efficiency.

The influx of information technology to the developing world has increasingly shown its impacts when information technology usage has become a part of daily life. Like its features, online apps have altered the way people interact and do daily activities, especially in urban areas. Conceptually the neighborhood was developed as part of the town planning practice and theory for developed worlds, though it is a universal phenomenon. Therefore, the neighborhood idea requires several adjustments to fit the dynamic third-world country context.

The study aims to observe the characteristics of urban socio-spatial changes in correlation with the use of online apps and review the extent to which it will modify the essential elements used in defining a neighborhood. It uses an exploratory approach to explain the relationship between spatial character changes and socio-cultural community in two neighborhoods in Bandung city as case studies. The compiled data’s correlational analysis shows several changes in the neighborhood elements characters, either spatial or social related, but they are responses to the inadequate public facilities. In conclusion, to some degree, it has not been significant enough to indicate the neighborhood changes and requires further research to see the advanced information technological impact on urban life

Pathumthani Province is on fertile plains and river valleys offering suitable land for agriculture. In 2019, A large number of agricultural lands, particularly farmland, is accounted for over 40 percent of the total province. However, the revenue of the agricultural sector contributes less than 3 percent of the gross provincial product (GPP), while the industrial sector becomes a major economic-based activity of this province, accounting for half of the GPP revenue. This research seeks an opportunity to enhance economic values and optimize the efficiency of agricultural-related supply chains. The research aims 1) to assess the need assessment of the agricultural sector in the issue of an intelligent exchange for sustainable economic transaction development, 2) to map a relationship between current situations of the agricultural sector and the commercial sector. Through the process of focus group and in-depth interview, the result of this study demonstrated the potential and current problems include the need to exchange agricultural goods/resources. The results could allow for an enhancement of the exchange of goods, especially agricultural products, to increase the potential of connectivity between producers and consumers in Pathumthani.

Micro-Hydro Power (MHP) is a solution to the need for renewable energy in the era of the industrial revolution 4.0. Its environmentally friendly effect has become a consideration for many people to consider implementing it in their respective places. One of the critical points to realize this is a sustainable MHP management model. This paper discusses the assessment of the MHP management model for electrification in rural areas in Indonesia. There are two objects in this research: Kunci Putih MHP in Jatirunggo Village, Semarang Regency, and the Mbakuhau MHP in Kamanggih Village, East Sumba Regency. This research aims to assess the management model of the Kunci Putih MHP and Mbakuhau MHP from the social-managerial, economic, and technical aspects. This study uses descriptive qualitative methods with gap analysis techniques. The results show that the two locations have different challenges based on three aspects that have been recognizing in international standards. The private sector manages Kunci Putih MHP with a National scale installation operated by the company directly. In contrast, Mbakuhau MHP manages by a credit union collaboration with National Electricity East Sumba. Kunci Putih MHP is driven by the private sector through auction and is responsible for maintenance, project engineering, repair, and equipment maintenance. Mbakuhau MHP can be successful in community-based management because IBEKA (Pro-Poor Public-Private Partnership) gave the community training during construction. The community provides technical training in leadership because Mbakuhau MHP is an electrification solution for isolated villages so that management is better carried out by the community. Therefore, the two cases cannot significantly be compared because they are different in power and scale.

Published: April 2021

The concept of sustainable development is widely known as an improvement towards the quality of buildings and the environment. Thus, this concept improves the comfort, health, satisfaction, and work performance of people. The city of Denpasar-Bali experienced very high population growth and decreased the quality of the environment and the balance between economic, social, and environmental factors. On the other hand, indigenous villages named Bali Aga villages that spread out across Bali island have building design and settlement concepts that always maintain harmony between humans, nature, and God. This concept has been proven to effectively respond to social, economic, and environmental problems for years. The aim of this paper is to discuss the suitable concepts and criteria for sustainable design and settlement of Denpasar city in the future by learning from Bali Aga concepts. The qualitative content analysis was applied to this study. Interviews with several professional architects in Denpasar were undertaken to explore the common approaches and barriers to sustainable design. Detailed information on indigenous design and settlement concepts gathered from surveys to selected Bali Aga villages. The result shows that Bali Aga’ building and settlement concept is fundamental to create suitable building and settlement concepts for the future development of Denpasar city to maintain economic, social, and environmental balance.

The problem of meeting housing needs for low-income communities is the inaccessibility of prices on the housing market. The Salatiga government has made efforts to meet this need by building low-cost houses for civil servants that utilize Government Land, thus keeping prices far below standard. As time went on, these cheap houses that belong to civil servants were not used as residential for the owners, but most of them became long-term investments. Based on these problems, the study aims to examine the impact of the low-cost house construction, namely KORPRI Housing in Prajamukti, Salatiga City of residential and investment functions. The method used is quantitative, primary data collected through field observations and interviews with residents and housing provider stakeholders. Meanwhile, secondary data obtained through government agencies and websites. The analysis technique uses a quantitative descriptive method and map overlay. The results showed that the function of houses is 60% for investment by rent out the housing to others, 30% as residential functions for civil servants, and 10% sold to other people. This condition is due to the status of the house is not the owner’s first home, strategic housing location, and triggered by an increase in land value. The contribution of this research is that previous researchers discussed a lot about the construction of cheap houses that received subsidies from the government, whereas in this study, the price reduction was the result of taking land assets belonging to the government in the form of Government Land.

Published: April 2021

Public transportation is an effort towards sustainable transportation. The City of Semarang has public transportation such as the Bus Rapid Transit (BRT), called the Bus Trans Semarang. The opening of the Bus Trans Semarang in 2009 continues to grow and increase the number of passengers. However, the number of passengers is still far below the expected target, even though the Bus Trans Semarang service continues to be improved. The decrease in the number of passengers further exacerbated by the existence of restrictions on community activities in Semarang City due to the pandemic COVID-19. Bus Trans Semarang services during the COVID-19 Pandemic need handled or minimized to reduce the risk of spreading COVID-19 to passengers when using the Bus Trans Semarang. This study aspires to determine what service variables are based on passenger preference that needs improvement, especially in the new normal era. The hope is that by knowing these variables, services can be made on the Bus Trans Semarang to increase public transportation use while reducing private vehicles’ use. Thus, Bus Trans Semarang can be suitable public transportation since users’ safety and comfort are essential for the success of public transportation in breaking the COVID-19 chain. This study uses the Importance Performance Analysis (IPA) of passengers. This study produces service variables expected by passengers, namely ease of mode change with other types of vehicles, timeliness of arrival at bus stops or terminals, and health protocol expectations on the Bus by both officers and passengers.

Bangkok has expanded considerably between 1991 - 1996. Which, the key factors contributed to the expansion consisted of real estate, business development and manufacturing industry. The horizontal expansion continued until 1991, after that Bangkok has increased its vertical expansion, especially in the inner and urban areas. The increasing in term of population causes the inner zone growth with high concentration rate, however, the suburban areas are characterized as of urban sprawls with the major expansion of road network. Those connectivities cut through the heart of Bangkok with the surrounding provinces. Currently, Bangkok has been continued its expansion in all directions, with high number of private cars and less users’ choices for public transportation, wich resulted in land-use changes, pollution, and traffic problems. The objective of this research is to study pattern of urban expansion and rate of changes in land use and infrastructure development by analyzing the land use changes in Bangkok and metropolitan and infrastructure development during the past 10 years, 2009 – 2019. The comparing of growth can be performed based on the study of satellite imagery, Path 129 Row 50 and Path 129 Row 51. From the result of analysis, it was found that road intersection density had an effect of the urban density areas. Finally, the Land Change Modeler (LCM) was used to explore and recommend for the appropriate ways for urban planning and development corresponding to the changes and responsive to the people in more sustainable way.

High-molecular-weight dextrin (WS-1000) was produced from waxy corn starch and enzymatically modified to link glucose by α-1,6 glycosidic bond at the terminal point of the glucose chain, forming MWS-1000. In this study, the physical properties of MWS-1000 were characterized, and the advantages of its use as a food modifier were described. From rheological and calorimetric studies, it was found that MWS-1000 does not undergo retrogradation, but it does not prevent the retrogradation of WS-1000, suggesting that they have no intermolecular interaction in solution. Investigation of the effect of MWS-1000 on the viscoelasticity of gelatinized wheat starch showed that in the linear viscoelastic region, storage modulus decreased and tan δ increased with increase in replaced MWS-1000 content. In addition, it was confirmed that gelatinized starch containing MWS-1000 showed viscoelastic behavior similar to that of commercially available custard cream.
