Menurunnya kunjungan wisatawan, pemutusan hubungan kerja, hingga pelaku usaha pariwisata yang gulung tikar terjadi akibat meluasnya virus covid-19 serta menurunnya kunjungan wisatawan ke objek dan daya tarik wisata. Penelitian ini menggunakan analisis bibliometric dengan alat analisis menggunakan aplikasi vosviewer 1.6.16.Kata Kunci : virtual tourism, destinasi, Covid-19VIRTUAL TOURISM AS AN ALTERNATIVE IN PANDEMIC COVID-19                                                                     ABSTRACTThe Covid-19 pandemic that occurred in almost all countries led to changes in people's behavior which required them to stay at home because there was an increase in confirmed positive cases so that some countries implemented lockdown policies. Indonesia is one of the countries affected by the Covid-19 virus implementing large-scale social restrictions to prevent the increasing number of positive cases in Indonesia, as a result of which various industrial sectors are affected, one of which is tourism. The decline in tourist visits, layoffs of employment, business actors who went bankrupt occurred due to the spread of the Covid-19 virus, and the decline in tourist visits to tourist objects and attractions. This study uses bibliometric analysis with analysis tools using the Vosviewer 1.6 application. This research discusses how the form of virtual tourism implementation that can be carried out by tourism businesses during the Covid-19 pandemic, as well as how virtual tourism has been researched over the last 10 years published by Scopus. Keywords: Virtual tourism, Destination, Covid-19

The existence of the co-19 pandemic is the cause of the implementation of large-scale social restrictions (PSBB), which resulted in almost all Indonesian people can only carry out their activities at home. As a result of the high activity being carried out at home, the by-products in the form of garbage also increased a lot. Both organic and inorganic waste, which often cannot be utilized. On the other hand, the educational process that usually occurs in schools now has to move to the house, with the mother acting as a teacher. Of the many stimulation needs that must be obtained by early childhood, religious values become the main thing that needs to be instilled as a foundation for them to be able to live their lives later. The purpose of this activity is to improve the ability of parents to use waste as a medium of Islamic learning in children. The activity was carried out in the South Tangerang area, with 15 participants having pre-school age children. The activity was carried out using the method of presenting material using a zoom cloud meeting, giving video tutorials, presenting the results of the work, and giving assignments. The results of the activity show that there are many media that participants can produce based on waste, especially cardboard and plastic, to be used in Islamic religious learning in early childhood.

Rank Dominance

Since 1991, India has cautiously and slowly opened almost all the sectors, except a few related to strategic importance, for foreign investors. Degree of openness of various industrial sectors for FDI has been increased to the extent of 100 percent by consistently liberalizing industrial policies of the sectors. The purpose of the paper is to study pattern and trends of sectoral distribution of FDI within the background of the first generation reforms and liberalized industrial policies during 1991-2001. The paper has used series of the dynamics and stylistic indices and statistical tools such as three level indices, index of rank dominance, and correlation matrices for explaining the pattern of FDI distribution across sectors during 1991-2001. The results show that electrical, transportation, chemical, telecommunication, and service sectors are most dominating sectors and represent almost 75 percent of total FDI received during 1991-2001. Index of rank dominance indicates distribution of FDI across the sectors is top heavy.

Understanding and being able to measure, analyze, compare, and contrast the image of a tourism destination, also known as tourism destination image (TDI), is critical in tourism management and destination marketing. Although various methodologies have been developed, a consistent, reliable, and scalable method for measuring TDI is still unavailable. This study aims to address the challenge by proposing a framework for a holistic measure of TDI in four dimensions, including popularity, sentiment, time, and location. A structural model for TDI measurement that covers various aspects of a tourism destination is developed. TDI is then measured by a comprehensive computational framework that can analyze complex textual and visual data on a large scale. A case study using more than 30,000 images, and 10,000 comments in relation to three tourism destinations in Australia demonstrates the effectiveness of the proposed framework.

A study has been mode of transport-controlled mass transfer-controlled to particles suspended in a stirred vessel. The motion of particle in a fluid was examined and a method of predicting relative velocities in terms of Kolmogoroff’s theory of local isotropic turbulence for mass transfer was outlined. To provide a more concrete visualization of complex wave form of turbulence, the concepts of eddies, of eddy velocity, scale (or wave number) and energy spectrum, have proved convenient. Large scale motions of scale contain almost all of the energy and they are directly responsible for energy diffusion throughout the stirring vessel by kinetic and pressure energies. However, almost no energy is dissipated by the large-scale energy-containing eddies. A scale of motion less than is responsible for convective energy transfer to even smaller eddy sires. At still smaller eddy scales, close to a characteristic microscale, both viscous energy dissipation and convection are the rule. The last range of eddies has been termed the universal equilibrium range. It has been further divided into a low eddy size region, the viscous dissipation subrange, and a larger eddy size region, the inertial convection subrange. Measurements of energy spectrum in mixing vessel are shown that there is a range, where the so called -(5/3) power law is effective. Accordingly, the theory of local isotropy of Kolmogoroff can be applied because existence of the internal subrange. As the integrated value of local energy dissipation rate agrees with the power per unit mass of liquid from the impeller, almost all energy from the impeller is viscous dissipated in eddies of microscale. The correlation for mass transfer to particles suspended in a stirred vessel is recommended. The results of experimental study are approximately 12 % above the predicted values.

Abstract There are two broad views as to why people stay poor. One emphasizes differences in fundamentals, such as ability, talent, or motivation. The other, the poverty traps view, emphasizes differences in opportunities which stem from access to wealth. To test between these two views, we exploit a large-scale, randomized asset transfer and an 11-year panel of 6,000 households who begin in extreme poverty. The setting is rural Bangladesh and the assets are cows. The data supports the poverty traps view—we identify a threshold level of initial assets above which households accumulate assets, take on better occupations (from casual labor in agriculture or domestic services to running small livestock businesses), and grow out of poverty. The reverse happens for those below the threshold. Structural estimation of an occupational choice model reveals that almost all beneficiaries are misallocated in the work they do at baseline and that the gains arising from eliminating misallocation would far exceed the program costs. Our findings imply that large transfers which create better jobs for the poor are an effective means of getting people out of poverty traps and reducing global poverty.

Abstract O. ficus-indica is highly valued as a fruit-producing cactus, also yielding 'leaves' that are used as a vegetable and browsed by livestock. It has been introduced widely from its native Mexico to almost all countries where the climate is suitable. The fruit is very rich in vitamin C and is exploited commercially in many areas. Many countries, especially in Asia, have recently established large-scale commercial plantations. However, O. ficus-indica, like several other species of Opuntia, have been known to spread and become invasive weeds. Historical records, however, appear to indicate a time-lag of about 100 years between introduction and the beginnings of invasive spread thus the actual risk may be low.

Predictive models of friction-induced vibration have proved elusive despite decades of research. There are many mechanisms that can cause brake squeal; friction coupled systems can be highly sensitive to small perturbations; and the dynamic properties of friction at the contact zone seem to be poorly understood. This paper describes experimental and theoretical work aimed at identifying the key ingredients of a predictive model. A large-scale experiment was carried out to identify squeal initiations using a pin-on-disc test rig: approximately 30,000 squeal initiations were recorded, covering a very wide range of frequencies. The theoretical model allows for completely general linear systems coupled at a single sliding point by friction: squeal is predicted using a linearised stability analysis. Results will be presented that show that almost all observed squeal events can be predicted within this model framework, but that some subsets require innovative friction modelling: predictions are highly dependent on the particular choice of friction model and its associated parameters.

Spines are common morphological features found in almost all major biological groups offering an opportunity to explore large-scale evolutionary convergence across disparate clades. As an example, opuntioid cacti have spines with barbed ornamentation that is remarkably similar in form and scale to that found on porcupine quills, suggesting specific biomechanical convergence across the animal and plant kingdoms. While the mechanics of porcupine quills as defensive mechanisms has been previously tested, the mechanics of cactus spines (which have evolved to fill a number of functions including defence, climbing and dispersal) has not been characterized. Here we study the puncturing and anchoring ability of six species of cactus, including both barbed and non-barbed spines. We found that barbed spines require less work to puncture a variety of targets than non-barbed spines. Barbed spines also require more work than non-barbed spines to withdraw from biological materials, owing to their barbs engaging with tissue fibres. These results closely match those found previously for barbed versus non-barbed porcupine quills, implying biomechanical convergence. The variation in performance of barbed versus non-barbed spines, as well as between barbed spines from different species, is probably tied to the diversity of ecological functions of cactus spines.

Abstract A novel dual-band conformal surface plasmons (CSPs) waveguide is designed and well studied in this paper. In earlier researches, we have recognized that electromagnetic field of CSPs waveguide are always confined to a sub-wavelength area and have a strong potential to be applied in devices designing. However, almost all of the earlier CSP structures is mainly focus on the fundamental mode characteristics with only single resonance frequency. Here we propose a innovative dual inverted-L structure with excellent performance not only on the fundamental mode but also on a new upper mode. This structure operates in microwave frequencies regime and shows outstanding frequency tunability characteristic. Being different from frequency characteristics in the earlier CSP waveguides which always used to be designed single-frequency device, dual-frequency tunability can be obtained via the dual L-type bending branch of the periodical CSP structure. In present paper, we also realize a tunable dual-frequency filter by changing the scaling factor of inverted-L stubs.

This paper is based on my research experience in an area that was the scene of a massacre: Bentalha, a hamlet, 30 km away from the Algerian capital Algiers. This massacre took place on September 22-23, 1997 during the “black decade” (1991-2001), a period of the civil war during which 150,000 people were killed, 7,000[i] disappeared and 1 million internally displaced. After a background section on the history of this conflict, the paper describes the setting where my fieldwork took place. This article discusses my experience on the field as well as the emotions such as frustration, fear, anxiety and vicarious traumatization that I experienced in the process. It also addresses questions of self-reflexivity, positionality and the insider/outsider status. I am writing from the perspective of an Algerian sociologist trained in France, yet my experience in doing fieldwork “at home” can be useful to other scholars who do or plan to do fieldwork in dangerous places in their countries or societies.Notes[i]. It is very hard to obtain an accurate estimate of the total number of victims. However, the Algerian President, Abdelaziz Bouteflika declared during a press conference in Paris on June 2000 that the number of victims was 150,000.
