ABSTRACT

The Covid-19 pandemic has impacted the socio-economic well-being of people either in urban or rural areas. The Covid-19 cases and fatalities that concentrated in major urban areas in Malaysia. However, as the pandemic progressed, the rural community faced health vulnerability due to the Covid-19 pandemic threat. Among the significant impacts of the Covid-19 pandemic are income generation, economic activity work, and health vulnerability, especially the rural community involved in rural economic activities such as agriculture and fishery. Therefore, this paper aims to investigate the impact of the Covid-19 pandemic on the socio-economic well-being of rural communities in Malaysia. The case study selection is in Mersing, Pontian and Batu Pahat involving three villages using GIS mapping. The methodology used is quantitative research through a household survey conducted using 182 heads of households based on the economic and social dimensions. The finding reveals that most of the target group experienced a decline in income generation, economic activity restriction, and education issues. Furthermore, there are also decreasing in the economically active population (age 15-60) in the village. As a result, this study is essential in formulating a post-Covid-19 recovery plan regarding socio-economic well-being impacts and the revival of rural community well-being in Malaysia through Geographic Information Systems (GIS) mapping.

ABSTRACT

The COVID-19 pandemic outbreak in early 2020 impacted people’s lives and the working environment and led to a drastic change in human activities. This has opened a window to analyze the people’s response to the safety measures implemented to contain the virus, which can be reflected and monitored using Night-time light (NTL) images. This study aims to demonstrate the use of NTL images captured by satellites to detect changes in human activity in the UAE before and during the pandemic. The study period will include the pandemic year and the previous years (2017-2019) will be used as a control. Raw NTL data was pre-processed to obtain cloud-free radiance images through which the monthly average radiance was calculated. The monthly average radiance is categorized into three classes: residential, commercial, and roads. The radiance levels during the lockdown were compared against the months prior to the restriction imposed. The results revealed that the roads category showed the highest decrease in radiance levels due to the enforcement of the safety measures, followed by the commercial category, whereas the least reduction was observed for the residential category. The results show how NTL radiance could be used in monitoring the changes in human activities.

ABSTRACT

The outbreak of diseases such as the pandemic Covid-19 is a critical problem that has emerged throughout the world. The outbreak is believed to be originated from Wuhan, China in December 2019. In February 2020, World Health Organization declared the name of the virus as Covid-19 and it has become a global pandemic in March 2020. This paper aims to review articles related to the application of GIS spatiotemporal analysis and web-based mapping for the Covid-19 pandemic. GIS spatiotemporal analysis is used to track the pattern of the Covid-19 and web-based mapping-based mapping is used to visualize the Covid-19 cases. This proves that GIS is a helpful tool to determine and track the transmission pattern and visualize the Covid-19 cases so that early mitigation can be done to combat the virus

ABSTRACT

Sustainable coordination and certainty of delivery are essential to achieving holistic COVID-19 vaccination, which covers the whole country. On November 4th 2020, the National Security Council (NSC) has structured the COVID-19 Risk Area Geo-Data Working Group, which consists of the Ministry of Health Malaysia (MOH), Malaysian Administrative Modernisation and Management Planning Unit (MAMPU), Department of Survey and Mapping Malaysia (JUPEM), Department of Statistics Malaysia (DOSM), PLAN Malaysia and Malaysian Space Agency (MYSA). As of February 2021, Malaysia has access to 66.7 million doses of COVID-19 vaccines supplied through the COVAX Facility and initial purchases from 5 vaccine manufacturers. Vaccination for COVID-19 is voluntary and will be provided free of charge to all Malaysian citizens and non-citizens in three phases. JUPEM through the Defence Geospatial Division (BGSP) has been entrusted to develop a Web GIS application, after a string of successes in developing Joint Common Operation Picture (JCOP) in the early stages of transmission of COVID-19. BGSP has developed Web Applications and Dashboards to provide an overview that can help in the planning, implementation and operation of vaccination centres for the National COVID-19 Immunization Programme (PICK) in Malaysia.

ABSTRACT

Coronavirus 2019 (COVID19) has now become a pandemic. In the early stages of the pandemic, Kota Kinabalu was one of the districts in Sabah with the greatest number of COVID19 positive cases. Despite the government’s announcement of the Movement Control Order (MCO), some residents were unable to follow the rules. As a result, the number of COVID19 positive cases in Sabah has increased, particularly in the Kota Kinabalu district. The increase of COVID 19 cases is indeed influenced by the behavior of the population in a place. The behavior of the population during previous pandemics has already shown how human attitudes can affect the spread of disease in the area. In Sabah, it is also seen to occur, such as violating the movement control order. Due to a shortage of manpower, it is difficult to identify and monitor residents who violate this MCO. Geographical factors in Sabah are also among the reasons why authorities find it difficult to keep control over all areas. In addition, the lack of technology, such as Geographic Information System (GIS), has made it difficult for authorities to monitor all locations. As a result, using Principal Component Analysis (PCA), this study was undertaken to identify the primary determinants of population behaviour that cause the spread of COVID19, which was then mapped using Geographic Information System (GIS). Only zones that registered positive cases of COVID19 from March to August 2020 were included in this study, which included a total of 100 respondents in the Kota Kinabalu area. Population behaviour, factor location, and responder location are among the data sources. To investigate the pattern of population behaviour in Kota Kinabalu, this study used factor analysis using PCA and the classification method using GIS. The study’s findings include a behaviour pattern map for the Kota Kinabalu district, which influences COVID19 distribution in the early phases of the pandemic. This study can assist various parties in identifying a potential area in Kota Kinabalu that has a high risk of COVID19 infection.

ABSTRACT

Implementation of remote sensing in agriculture helps to enhance crop growth monitoring especially during the Covid-19 pandemic. To enhance black pepper growth condition, a study was conducted at two study sites in Bintulu, Sarawak. Hence, this study aims (i) to construct a black pepper growth monitoring at different levels of elevation in Suka Farm (SF) and Taime Farm (TF);and (ii) to integrate limited ground data and NDVI time series from Landsat 8OLI for black pepper growth monitoring. Elevation maps were generated using Natural Neighbor (NN) based on the ground data analysed using ArcGIS 10.4 Software. Three elevation levels were classified into the lower, middle, and upper levels. Observational ground data and NDVI time series of Landsat 8 OLI were calculated using SAS 9.4 software. All parameters then correlating with the elevation levels using Pearson Correlation Coefficient. Optimum growth of black pepper growth in SF and TF was identified at an elevation range between 39m–50m. The NDVI time series also indicated equivalent results as the ground data. This study proposed that the elevation of an area gives a significant impact on black pepper growth. Besides, the NDVI time series of Landsat 8 OLI was feasible for monitoring black pepper growth.

ABSTRACT

Covid-19 is caused by aetiological agent for SARS-CoV-2. The disease has caused pandemic responsible for deaths and economic loss worldwide. Therefore, novel drugs of covid-19 primarily using herbs are urgently needed. Cabya (Piper retrofractum Vahl.) is a popular spice and also traditionally applied for herbal medicines. This study conducted an in silico experiment to screen methanolic active compounds in cabya and test their inhibitory activities against main protease enzyme (Mpro) as receptor of SARS-CoV-2. The in silico approach complied with molecular docking protocols enabling to evaluate performance of the compounds to inhibit Mpro. Two common drugs were used as control, i.e. chloroquine and ivermectin. As the results, molecular docking showed a promising inhibition by active compounds in cabya;in this regard, beta-sitosterol demonstrated the strongest inhibition against Mpro with binding affinity -7,5 kcal/mol, which is better than chloroquine (-4.8 kcal/mol) and close to ivermectin (-8,5 kcal/mol). The interaction resulted from two hydrogen bonds with amino acids ARG A131 and ASP A289 at distance of 15Å and 2,49 Å, respectively. The inhibition site of beta-sitosterol was similar to that of ivermectin. This research revealed the potential use of cabya for covid-19 treatment through restriction of molecular binding between virus and receptor.

ABSTRACT

COVID-19 has affected the operation of many sectors including the agriculture sector. The outbreak of COVID-19 has effect operational activities especially in the Oil Palm plantation. This study is aimed to identify the effect of pandemic COVID-19 on operational activities in oil Palm production. The effect of operational activities that are being studied is a worker’s health condition, access to input supply, the management of field operation, and the cost of production. Through data collection method by questionnaire were distributed to 35 respondents from Ladang Kumpulan Melayu Kota Tinggi, Johor. Based on demographic analysis, most of the respondents have more than 20 years of experience in the field. Based on the study, the management of field operation is the major effect that influences the oil palm production with β= 0.486 and correlation for relationship is 0.017. When the new legislation of standard operating procedure is implemented then it will influence oil palm production. The access to input supply has a significant difference with oil palm production due to pandemic COVID-19 rather than the other three variables. If the supply is limited, it also will affect the quality of the yield. When there is a movement control order (MCO), the company cannot access the input needed for operation in the oil palm plantation

ABSTRACT

The World Health Organization recommends limiting the consumption of processed and red meat products due to the increased risk of developing cancer of the gastrointestinal tract of people and a decrease in immunity with a new coronavirus infection. An alternative to red meat is rabbit meat, rich in polyunsaturated fatty acids, which prevent carcinogenesis, causing apoptosis, control the cell cycle and the production of eicosanoids. For the production of meat products, dietary supplements are traditionally used to improve the consistency and increase the yield of finished products, which in some cases do not meet safety requirements. In this context, the use of rationally selected biopolymer plant complexes in combination with a protein component of animal origin is promising and can be safely used in the production cycle of products of various compositions. To obtain meat products based on rabbit meat using biotechnological approaches, protein-carbohydrate complexes containing sprouted forms of legumes, jerusalem artichoke dietary fibers and composites of animal and vegetable origin have been developed. Protein-carbohydrate complexes contained 17.2 – 23.7% protein, 2.20 – 4.70% fat and 18.2 – 21.8% dietary fiber in their composition. And conducting a biological assessment on a test culture indicates that the developed protein-carbohydrate complexes are physiological for biotest, that is, they have the necessary level of safety, which allows them to be recommended for enriching meat-based food systems and expanding the range of products produced by meat processing enterprises.

ABSTRACT

The hotel industry is one of the sectors that is heavily affected by the COVID-19 pandemic. Compensating for this lost revenue requires understanding which aspects of guests’ priorities have changed, including their feelings about sustainable practices. Drawing from an online survey with 250 adults who were at least 18 years of age, described themselves as familiar with sustainable practices, and stated they had stayed in a hotel both before and during the pandemic, this study finds that the pandemic had a significant impact on their attitudes towards sustainable practices. Although they believe that hotels’ adopted protocols are adequate to protect them from COVID-19, they do not intend to adopt sustainable practices in the pandemic era.

ABSTRACT

The article discusses the principles for the formation of a sustainable architecture of office spaces in the context of such a global environmental problem as a pandemic. Current trends and general principles of the formation of office spaces in the post-COVID period, the direct relationship between the health of employees, the office ecosystem and the concept of “typology of organizational cultures of the company” are analysed. The main attention is paid to the architectural aspects of organizational models of office objects. The principles and techniques for creating a healthy efficient workspace, which a sustainable office complex should have, are formulated. The reconceptualization of the organization of office activities and methods of adapting traditional office spaces in a pandemic with the prospect of their development in the post-COVID period are considered. The most “viable” types of office spaces and models of workplace organization are singled out in these conditions. It is based on the opinions of business experts related to the further development of office activities, possible changes in internal strategies in the organizational culture of companies. Optimal architectural solutions for the organization of safe and demanded office spaces are proposed.

ABSTRACT

Current house setup presents inadequacies of flexibility that bring into unsuitable situation, which examine resilience during the COVID-19 pandemic. Social distancing restrictions cause residents to carry out all activities inside the house, including Architecture students. Creativity as an attitude that is needed by Architecture students’ needs to be maintained even if online learning is implemented. This research was conducted on Pradita University students who had experienced architectural studio learning activities, during the protocol period for maintaining the established distance learning. The previous study is adaptation has occurred with layout modifications to residential during the pandemic, further presumption that the house can become resilient by learning process and self-organization process to produce a creative environment. The research method uses direct observation by assigning the respondents themselves as observers who report the observations. The results indicate that space as “a process manifestation” is present in all respondent area in their house. While the space as “social dimension” and “knowledge repository” are held by most of the respondents. Meanwhile, space as “an indicator of culture” and “source of stimulation” was only raised by half of respondents. This paper aims to investigate the implementation of creative space in residential homes. The research results are expected to be used for improving housing providers so as residents can carry out self-organization as a resilience architecture.

ABSTRACT

The Covid-19 pandemic has impacted changes in services and work systems in hospitals worldwide, including Indonesia. The Indonesian Ministry of Health’s policy calls for hospitals to accept Covid-19 patients, requiring hospital management to adjust in the design of their facilities. This study aims to examine the changes made before receiving and while treating Covid-19 patients, considering the contagious character of the disease. It focuses on the hospital’s inpatient installation that chambers infected patients for a certain duration of time. The research was carried out by comparing before-after hospital plan documents and conducting interviews with hospital management along with a field survey to Rumah Sakit Khusus Ginjal (RSKG) Nyonya Habibie in Bandung. Changes reviewed include those related criteria sourced from guides and regulations mentioning standards of Covid-19 inpatient facilities. These criteria, divided into two aspects— zoning-circulation paths and ventilation-air circulation – are the basis of quantitative evaluation, using Likert scale. The result of this phase is to find whether alterations done are enough to meet the newly set standards for Covid-19 inpatient installation and be able to reduce the chance of transmission.

ABSTRACT

Covid 19 pandemic affected learning methods from offline to online. All parties involved in learning need to make various adaptations so that the learning process can run effectively. Students are required to focus on education at home (School from Home/SFH). The architectural learning method prioritizes practice in designing called Studio Class. It causes problems when it comes to changing the learning method online. Place of residence also plays an essential role. When they are SFH, the students live in private houses, rented houses, and boarding houses. The purpose of this study is to determine whether characteristics of the learning room environment (thermal, lighting, and audial) in the living space have a major impact on the success of SFH learning. This study employs quantitative research to ascertain the variables affecting environmental comfort through online questionnaire data. The thermal element is determined to have the greatest impact on overall comfort. Audial comfort is critical in breaking students’ concentration when performing studio exercises. In general, students who live in boarding houses do not feel disruption from surrounding noise, however students who live in private homes do.

ABSTRACT

This study identifies and quantifies floating macro litter and macro plastic from Deli River Medan during pandemic Covid-19. Macro litter transport consists of floating items at surface, suspended in water column and transport over on riverbed. Litter was collected from 5 location along 11.6 km using static trawls with a height of 150 cm and width of 300 cm with a square mesh size of 0.5 cm. Sampling was done in July, and during selection, 40 cm of net’s height was constantly submerged for one hour. This study found that macro litter was 19.26 kg/h with 65.2% as anthropogenic waste, 34.3% as macro plastic, 0.3% as metal, and 0.15% as medical waste. The composition of macro plastic has various variants, namely food containers, plastic bags, food packaging, sanitary packaging, and mineral water packaging with percentages of 10.21%, 67.89%, 8.35%, 4.36%, and 9.18%. The macro plastic abundance was obtained at 2,476 x 10-4 kg/m3. This study showed a significant increase in plastic consumption during the pandemic, especially plastic bags because it is dominated in all locations.

ABSTRACT

Wheat and rice are plants that contain many health benefits, such as chlorophyll, protein and phenolic compounds, which are very suitable for consumption during the current COVID-19 pandemic. This study aims to observe the growth response of wheat and rice with various types of growing media. The use of the right planting media is expected to provide good content for wheat and rice plants so that they can be used as health drinks that are good for consumption. This study used a factorial completely randomized design using two factors, where : factor I = plant species with T1 (wheat) and T2 (rice) and factor II = type of growing media with P0 (top soil), P1 (top soil: husk charcoal). ) (1:1), P2 (top soil:cocopeat) (1:1), P3 (top soil:sawdust) (1:1) and P4 (top soil:husk charcoal:cocopeat:sawdust) (1:1:1:1). The results of this study indicate that the highest plant height data was obtained from rice plants with an average top soil planting medium of 18.13 cm. The highest protein content was found in wheat with top soil growing media: sawdust with a yield of 2.20 L/g. So it can be said that wheat can be used as a health drink because it contains high protein.

ABSTRACT

Anticipated future reductions in aerosol emissions are expected to accelerate warming and substantially change precipitation characteristics. Therefore, it is vital to identify the existing patterns and possible future pathways of anthropogenic aerosol reductions. The COVID-19 pandemic prompted abrupt, global declines in transportation and industrial activities, providing opportunities to study the aerosol effects of pandemic-driven emissions changes. Here, measurements of aerosol optical depth (AOD) from two satellite instruments were used to characterize aerosol burdens throughout 2020 in four Northern Hemisphere source regions (Eastern & Central China, the United States, India, and Europe). In most regions, record-low measures of AOD persisted beyond the earliest ‘lockdown’ periods of the pandemic. Record-low values were most concentrated during the boreal spring and summer months, when 56% to 72% of sampled months showed record-low AOD values for their respective regions. However, in India and Eastern & Central China, the COVID-19 AOD signature was eclipsed by sources of natural variability (dust) and a multi-year trend, respectively. In the United States and Europe, a likely COVID-19 signal peaks in the summer of 2020, contributing as much as −.01 to −.03 AOD units to observed anomalies.
