Student Satisfaction and the Future of Online Learning in Higher Education: Lessons from a Natural Experiment
Authors: Wright Graham , Volodarsky Sasha , Hecht Shahar , Saxe Leonard
Published: March 2023

Although there is substantial research on the effectiveness of online learning at the individual class level, there is little reliable data on how a shift to a mostly or fully virtual campus would impact undergraduates’ satisfaction, engagement, and academic achievement. Until the COVID-19 pandemic, the limited adoption of widespread online learning at selective schools and challenges of selection bias hindered a reliable assessment of such a shift in selective institutions. After the initial period of “emergency remote learning” in 2020, many selective institutions continued widespread online learning in the second year of the pandemic. Treating the expanded deployment of online learning as a natural experiment, the present study assesses the impact of frequent online learning during the spring semester of 2021 on representative samples of undergraduate students at three selective, four-year universities. The study finds that students who participated in classes that met in person at least once a week had higher evaluations of faculty engagement and higher overall levels of academic satisfaction, compared to those who never or rarely participated in an in-person class. This relationship appears less pronounced for Black and Asian students than for White students but does not vary significantly by gender. Although online learning has great potential, these results suggest a need to better understand the conditions that will support an expansion of online learning that can maintain student satisfaction.

Authors: Ahlf Michael , McNeil Sara G.
Published: March 2023

This systematic review examined research on moderators in asynchronous online discussions (AODs) through a review of 52 sources published over the past four decades. Areas of interest included conceptual frameworks cited in research, publication trends, instructional contexts, research methods and characteristics, and descriptions of the role of the moderator with implications for practice. Results indicate: (1) nearly half of the publications did not cite a conceptual framework focused on moderation; (2) the field is diverse with a wide variety of themes for research designs, outcomes, foci, and questions; (3) half of reviewed publications involved case studies or similarly limited study designs; (4) the majority of publications collected data on students in higher education, but there was a lack of consistency in the reporting of demographic information; (5) research foci tended toward investigating peer moderators or the role of the instructor; (6) research questions tended to focus on strategies of moderators or student performance and discussion quality; (7) most definitions or expectations of a moderator included discussion and social management duties. We conclude by discussing the implications of some of the findings and future research options.
A Systematic Review of the Research Topics in Online Learning During COVID-19: Documenting the Sudden Shift
Authors: Doo Min Young , Zhu Meina , Bonk Curtis J.
Published: March 2023

Since most schools and learners had no choice but to learn online during the pandemic, online learning became the mainstream learning mode rather than a substitute for traditional face-to-face learning. Given this enormous change in online learning, we conducted a systematic review of 191 of the most recent online learning studies published during the COVID-19 era. The systematic review results indicated that the themes regarding “courses and instructors” became popular during the pandemic, whereas most online learning research has focused on “learners” pre-COVID-19. Notably, the research topics “course and instructors” and “course technology” received more attention than prior to COVID-19. We found that “engagement” remained the most common research theme even after the pandemic. New research topics included parents, technology acceptance or adoption of online learning, and learners’ and instructors’ perceptions of online learning.
Passive Participation in Collaborative Online Learning Activities: A Scoping Review of Research in Formal School Learning Settings
Authors: Choi Hajeen , Hur Jaesung
Published: March 2023

This scoping review summarizes studies on passive participation in collaborative online learning activities that used computer-mediated communication tools in school settings. A total of 42 articles spanning about 20 years were explored. ERIC and three main journal indexes from Web of Science were used to locate articles. For each year searched, there were only one to five studies that investigated passive participation, indicating that not many researchers have examined this topic in general. Most studies used mixed methods and were conducted in higher education settings in asynchronous online discussions. Three terms have been used to discuss the notion of passive participation: lurking for read-only behavior, legitimate peripheral participation for low contribution, and free riding for no contribution. Studies on passive participation have mainly explored four topical areas: motivational factors and reasons, participation types and behavioral patterns, effect on learning outcomes, and pedagogical strategies for de-lurking. Most studies have investigated passive participation as one of the behavior patterns among various types of participation. A few studies have solely examined read-only behaviors. The notion of passive participation varies among researchers and should therefore be redefined. Overall, there have been few studies on the topic of passive participation and those that have been conducted reveal some inconsistencies in their findings, indicating the topic requires further investigation. Future studies on this topic are urgently needed due to the forced shift to online courses precipitated by the pandemic. While instructors are also responsible for supporting their learners in this unprecedented context, researchers should investigate ways to help instructors better understand passive participants and encourage active learner participation in collaborative online learning space.

Authors: Al-Zawbaee Obaid M. , Mahmood Nozad H.
Published: March 2023

The panel data models have gained great attention because they consider the effect of changing time series and the cross-sectional units. It has a higher number of degrees of freedom and is, therefore, more efficient.  Our research aims to build the most efficient model using panel data through comparison among six statistical models and to determine the most efficient model through the mean squares of error (RMSE) and the coefficient of determination (R2). Using the EViews-12 package to apply to two data sets to determine the most efficient model. The more critical findings are that the hypothesis assumed by the research states that the accuracy of the adopted models varies. Furthermore, it was found by building six types of panel data models that the best model is the (Two-way Fixed Effect Model) because it achieves the lowest value of (RMSE) and the largest value of R2.

Rational nutrition as a health factor: realities and prospects
Authors: Novoselova E. N.
Published: March 2023

The article discusses how the culture of food, its rationality and quality affects the health of Russians. The dietary style of Russians is analyzed on the basis of the latest statistical data and literature analysis. It is concluded that despite some positive developments in this area, the quality of nutrition of Russian residents is far from ideal. The author of the article seeks to understand how population understands the concept of healthy nutrition, whether the understanding of this phenomenon differs depending on socio-demographic characteristics. Particular attention is paid to gender differences regarding nutrition and the consequences of these differences. Article focuses on the obstacles that Russians face on the way to improving their diet. One of such obstacles is economic difficulties and the inability to buy healthy foods due to their high cost, especially in large families and single-parent families, whose food quality is lower for a number of socio-economic reasons. An equally important factor limiting the possibilities of Russians in the field of nutrition is the lack of awareness and education of the majority of the population regarding healthy lifestyle in general and nutrition in particular.

The empirical basis of the work is comprised of the data of the World Health Organization (WHO), the Federal State Statistics Service, the Public Opinion Foundation and the All-Russian Public Opinion Research Center.
Promoting special interests of public companies
Authors: Vasiliev V. P.
Published: March 2023

The basis for the analysis of special interests in economic activity is the research of neo-institutional theory, which interprets the phenomenon of lobbying as a process of exchange between the state and business, in the field of competition for influence in decision-making and resource allocation based on the manifestation of differing interests. Competition unfolds in two areas of interaction – the formation of institutional norms that directly determine the economic result of business and for resources for the implementation of investment programs. The features of Russian economic lobbying and new forms of promoting economic interests in government bodies are highlighted. In large companies, lobbying becomes the sphere of specialized GR management, working on issues of strategic and operational interests of companies with representatives of the authorities. It is shown that the activity of GR is modified under the influence of the practice of implementing large projects, embedding business in public administration programs. Collective lobbying in the form of various unions, associations and associations of business structures that are in constant dialogue with the authorities has received significant development and effectiveness in achieving the goals of implementing special sectoral interests. It is determined that the current trend of lobbying is the articulation of special interests of business in strategic areas of economic dynamics, where administrative and financial resources of the state are concentrated. Traditional and new motives of lobbying are moving into the sphere of forming a new investment cycle, strategic national ones. projects, digital development and solutions to environmental problems.
The Eurasian vector of development of the Russian Federation: exodus to the East
Authors: Bredikhin A. V.
Published: March 2023

In the foreign policy and economy of the Russian Federation, the coordinate system is being turned to the East. This logic fits into the framework of the Eurasian ideology. It also correlates with China’s desire to create a global center of confrontation with the United States. This problem is being actualized through a special military operation of the Russian Federation in Ukraine and a “hybrid war” with the countries of the collective West. The formation of new blocs, the “Eastern Entente” leads to a change in the geopolitics of Eurasia and the world as a whole. Within the framework of the research, the author uses the following methods: historical, geopolitical and civilizational approaches, concrete historical, observation and generalization, systemic socio-political and ethnic analysis, synthesis. In the conclusions, the author comes to the opinion about the need to reformat existing supranational integration projects in the post-Soviet space, transform the architecture of relations in the political, economic and military spheres with the countries of East and Southeast Asia, and apply the Eurasian ideology as a state-forming one.
Blacksad, cómic, legado y fenómeno fans
Authors: Romero Benguigui Daniel
Published: March 2023

Originada en el 2000 por Juan Díaz Canales (guión) y Juanjo Guarnido (dibujo), la saga de cómics Blacksad se ha instituido como uno de los referentes más notorios en la narrativa gráfica negro-criminal, algo patente en los múltiples premios y galones que ha recibido, donde destacan los Eisner conseguidos en 2011, 2013 y 2015.

Por su impacto en el medio, la saga ha supuesto un fenómeno de masas, éxito mediante el cual se ha justificado su intermedialidad hacia otros medios. El presente artículo constituye un estudio monográfico sobre el personaje: desde su concepción y desarrollo en cómic, hasta su inspiración hacia medios interactivos como lo han sido Blacksad: Under the skin (2019) y Blacksad: El juego de rol (2015), donde han emergido nuevas interacciones por parte de los seguidores de la obra.
Cuff size, cuff placement, blood pressure state, and monitoring technique can influence indirect arterial blood pressure monitoring in anesthetized bats (Pteropus vampyrus)
Authors: Paranjape Vaidehi V. , Gatson Bonnie J. , Bailey Kate , Wellehan James F. X.
Published: March 2023

OBJECTIVE

Evaluate agreement between 2 non-invasive blood pressure (NIBP) techniques and invasive arterial blood pressure (IBP) in anesthetized bats using various cuff sizes and cuff positioning while also evaluating its performance during hypertension and hypotension.

ANIMALS

8 bats (1.1 ± 0.2 kg).

PROCEDURES

Bats were anesthetized with isoflurane in oxygen. NIBP was measured using oscillometric (NIBP-O) and Doppler (NIBP-D) techniques in the pectoral limb (PEC) and pelvic limbs (PEL) using 3 cuff sizes (1, 2, and 3). NIBP measurements were compared with IBP; systolic (SAPinvasive), mean (MAPinvasive), and diastolic arterial blood pressure (DAPinvasive) during normotension, hypertension, and hypotension. Hypotension was induced with isoflurane (3.8 ± 1.2%) and hypertension with norepinephrine (3 ± 0.5 µg/kg/min). Data analysis included Bland-Altman analyses and 3-way ANOVA. Results were reported as mean bias (95% CI).

RESULTS

NIBP-O monitor reported 29% errors, and experienced more failures with hypertension, cuff placement on PEC, and using a size 1 cuff. Across states, an agreement between NIBP-D and MAPinvasive with cuff 2 on PEL (−3 mmHg [−8, 1]), and NIBP-D and SAPinvasive with cuff 3 on PEC (2 mmHg [−5, 9 mmHg]) was achieved. NIBP-D over-estimated SAPinvasive and MAPinvasive during hypertension in both limbs with cuffs 1 and 2. Except during hypotension, NIBP-O underestimated MAPinvasive and DAPinvasive using a size 2 cuff on PEL.

CLINICAL RELEVANCE

In anesthetized bats, NIBP-O is unreliable for estimating IBP. NIBP-D shows acceptable agreement with MAPinvasive with cuff size 2 on PEL, and with SAPinvasive with cuff size 3 on PEC across a wide range of IBP values.

Published: March 2023

The present experiment aimed to evaluate the partial replacement of corn with chocolate byproducts or protected fats in the diet of lactating cows on feed utilization, blood profile, and lactation performance. Fifty multiparous Holstein cows (560±22 kg BW, 3±1 parity, 7±1 days in milk, and previous milk production of 34±3 kg/d), were randomly assigned to 5 treatments in a completely randomized design for 90 days. The control diet contained a concentrate feed mixture containing (per kg DM) 412 g concentrate feed mixture, 412 g corn silage, and 176 g berseem hay. The control diet contained 17.6% crushed corn (DM basis). In another treatment, the control diet was supplemented with 1 g chromium daily (Chromium diet). In the other diets, each kg of crushed corn grain was replaced with 600 g chocolate byproducts (CH diet), 400 g protected fats (PF diet), or 500 g of chocolate byproducts and protected fats mixture (1:1 DM basis) (CHPF diet), DM basis, and each of the diets was also supplemented with 1 g chromium daily. Both amounts of protected fats and chocolate byproducts had the same energy concentration as 1 kg of corn. Without affecting feed intake, the replacement increased (P<0.01) milk production, milk fat concentration, and feed efficiency. The replacement (P<0.05) increased the concentrations of plasma total proteins, albumin, glucose, cholesterol, triglyceride, and chromium in comparison with the control diet. Higher (P<0.001) nutrient digestibility was observed with CH, PF, and CHPF treatments. It is concluded that chromium supplementation did not affect feed utilization or cows’ performance; however, partial replacement of corn with chromium supplemented protected fat, chocolate byproducts or their mixture improved milk production and feed efficiency.
Sustainable Intensification – Reaching Towards Climate Resilience Livestock Production System – A Review
Authors: Singh Ruchi , Maiti Sanjit , Garai Sanchita , Rachna
Published: March 2023

An ability to prepare, recover and adapt to frequent climatic variation is called “Climate resilience.” climate change now places additional pressure on the cattle industry, particularly in developing nations, which threatens the livelihood of small farmers. In 2013 “Food and Agriculture Organization” reported that the livestock sector accounts for nearly one-third of agricultural gross production value globally. There are higher possibilities of the effective implications of sustainable intensification in the livestock production systems to determine production pathways that are more sustainable and productive with a minimum negative impact on the environment. The paper discusses the systematic review mingled with qualitative text analysis to explore the interrelation between sustainable intensification and resilient climate practices, specifically towards the livestock production system. The data for systematic review was taken from Scopus, Web of Science, and PubMed databases from 1995 till 2020, with total screened 94 articles in the final selection. The study’s results revealed that all approaches involving environment-friendly practices with higher production efficiency, resource use efficiency and reachable to every farmer were considered sustainable intensification. The relevance of this sustainability analysis to climate resilience is illustrated by considering different types of livestock systems with concerned practices. So, the inclusion of appropriate technology in an appropriate system will open the door for sustainable intensification in the face of a Climate-Resilient livestock production system and finally lead the farming community towards sustainable development.

Published: March 2023

This case report describes the lingual orthodontic treatment of a 28-year-old female patient who presented with a bimaxillary protrusion malocclusion, a hyperdivergent facial pattern, mentalis strain, and a ‘gummy’ smile. To achieve favourable occlusal and facial results, the four first premolars were extracted, and micro-screws utilised to provide maximum anchorage. With the widespread application of three-dimensional technology, a digital goal-oriented treatment plan was applied for its predictability and precision. A fully customised lingual appliance system with preset torque in the anterior teeth combined with ribbon-wise arch wires was placed to prevent excessive lingual inclination of the incisors during retraction. As a result, an attractive facial profile and a well-aligned dentition with ideal intercuspation was obtained.

Published: March 2023

Written in late summer of 2022, this article aimed to provide an overview on the intra-EU cohesion of the EU Member States that transformed the communist system into a democratic market economy in 1988–90. The study analyses the economic background of these states for sustainable catching-up in the European Union. The result is a picture of a divided CEE area, where some states showed macroeconomic imbalances and economic growth, while others started to catch up with the solid background of the eurozone membership or its future perspective. In terms of most parameters, Hungary is in the first group but – together with Romania – is also facing serious macroeconomic difficulties.

Published: March 2023

Our article examines the changes in the economic position of a Hungarian secondary city, Pécs, and its region in the post-crisis period from a labour productivity perspective. Our aim is to contrast results based on data of the city’s largest local firms from the Orbis Europe enterprise database with the results based on the EuroStat regional database. We assess local trends in a sectoral disaggregation and focus on the period between the two crises. Our results suggest that Pécs and its region face a persistent difficulty in attracting external resources and in retaining and generating endogenous resources.
Older adults experiencing and balancing the ambivalences of digitalisation in everyday life: Media repertoires as resources in domesticating emerging technologies
Authors: Lehtinen Vilma
Published: March 2023

Older adults have been found to conceive digital technologies as both helpful and problematic in their everyday lives. Based on a qualitative analysis of diaries and interviews with 40 older Finnish adults, this study identifies efforts they engage in to balance this ambivalence. I approach such balancing practices through the theoretical lens of domestication: the process of integrating technologies into everyday life. By combining the concept of media repertoire with the domestication approach, the findings illustrate how ageing individuals take advantage of their media repertoires in the process of making digitalised societies liveable. In order to include ageing individuals in societies that increasingly demand engagement with emerging technologies, then, means that services should be designed in ways that allow them to be integrated into older adults’ media repertoires that have been being formed for decades.

Published: March 2023

Introduction

The purpose of the research was to analyse the injuries of primary school children in the framework of organised sports activities at school and in clubs or associations, and in leisure time without professional guidance.

Methods

We surveyed 631 participants, of which there were 282 boys and 349 girls from eight Slovenian primary schools. Frequencies were calculated and a Chi-square test was performed.

Results

In physical education (PE) at school, 32% of the participants were injured in one school year, and there were no statistically significant differences in the number of injuries according to sex (p=0.18) and age (p=0.12). Most injuries were recorded in the lower extremities (50%), in the form of wounds. The participants were injured less often in PE at school than in a club or association, and more often than in their leisure time. The participants were absent from PE classes for longer after an injury in a club or association than in PE, while no significant differences in absences after injury were found. At school, the participants were most often injured in ball games, boys in football (43%) and girls in volleyball (19%). In activities in a club or association, we recorded the most injuries in boys in martial arts (18%) and dance for girls (19%). In their leisure time, boys suffered the most injuries from football (26%) and cycling, while girls suffered the most from running and rollerblading.

Conclusion

In the last ten years, the number of injuries in PE has increased in Slovenia. Based on the obtained results, we propose measures to reduce injuries and thus encourage more sports activities among children and adolescents, while ensuring their safety.
A Review on Modeling and Stability Aspects of Gas Foil Bearing Supported Rotors
Authors: S. Khamari Debanshu , Kumar Jitesh , K. Behera Suraj
Published: March 2023

Gas foil bearing rotor (GFBR) systems have received significant interest in the field of rotordynamics and vibration analysis. GFBR systems have a wide range of high-speed turbomachinery applications. Due to the high speed, these machines are susceptible to rigorous vibration and instability. Gas foil bearings instigate large amplitude of vibrations at startup and shut down and severe subsynchronous motions during high-speed operations. Over the years, numerous work has been done in the field of high-speed rotors supported on gas foil bearings. Significant improvement has been observed in the stability and feasibility of the GFBR systems. However, accurate model predictions of gas foil bearing still remain a challenge for its widespread usage in high-speed turbomachinery. A comprehensive review needs to be done to study the previous work and pave the way for future research. The current review is majorly divided into three sections. Firstly, various models used for the performance prediction of gas foil bearings are compiled. After that, major causes of instability that manifest during the experiments and practice with gas foil bearing supported rotors is illustrated. Lastly, the developmental attempts made to inhibit the instability is summarised. This paper presents an overall picture of the current engineering scenario and future prospects of the GFBR systems.

Authors: Gärtner Marcus , Brecher Christian , Neus Stephan , Recker Cornelia , Franken Mark , Engelmann Thomas , Wagler Ingo
Published: March 2023

To improve the manufacturing accuracy in the machining process, the stiffness of the machine tool spindle must be increased. One approach is to replace the conventionally used spindle bearings by tapered roller bearings to achieve a higher stiffness and load carrying capacity. However, the speed capability of this bearing type is limited, though can be enhanced by sufficient lubrication, especially in the critically loaded rib-roller-contact. The objective of this paper is to validate the lubricant influence on the speed capability of radially loaded tapered roller bearings. In various speed step runs, the operating behavior of the bearings under oil-air and grease lubrication was evaluated based on the outer ring temperature and the vibration level in the test rig. With oil-air lubrication, a speed parameter up to 900,000 mm/min could be achieved, whereas with grease lubrication, a speed parameter of 540,000 mm/min could be reached. In comparison, the setup with spindle bearings can achieve the highest investigated speed parameter of 900,000 mm/min with both grease and oil-air lubrication. For grease lubricated ball bearings, significantly higher temperature fluctuations are present with variation of the radial load. In the case of oil-air lubrication, the steady-state temperature improved with increasing oil viscosity.

Published: March 2023

The study determines the effect of saturated fatty acids (coconut oil) on the rheological and tribological properties of olive oil. The olive oil is blended with different proportions of coconut oil (10%, 20%, 30%, 40%, and 50%) and the different properties (flow behaviour and antiwear) are studied on Anton Paars rheometer and Four-ball tester respectively. The study reveals that the blends depict Newtonian behaviour with a decrease in the dynamic viscosity of the olive oil. Also, WSD decreases at a higher proportion of coconut oil in the blends with an improvement of 10.74% at a 50:50 ratio. The blending of two oils for the enhancement of the lubrication properties of biolubricants can prove beneficial in making them a suitable replacement for mineral oils.

The purpose of this research was to evaluate the refining of used lubricating oils (ULOs), and their possible use as drilling fluids. 17 treatments were evaluated and sulfuric acid and nonylphenol were used as reagents at concentrations of 0.12, 0.24 and 0.36 g/mL and temperatures of 40, 60, 80 and 100 °C. AT80 and AT100 ULOs treated at 80 and 100 °C without reagents, presented an average density of 0.84 g/cm-3, a viscosity of 76.3 and 75.3 cP, an electrical stability of 1,731.3 and 1,394.6 V and a flash point of 183 and 190 °C as higher. The ST40C1 and ST40C2 treatments, added with reagents, showed similar results to AT80 and AT100 in the evaluated variables, but they are more expensive treatments. According to the results, it is concluded that the refined ULO can be a substitute for the oil used in the formulation of oil-based drilling fluids.
Improving the Resistance to Wear and Mechanical Characteristics of Cladding Layers on Titanium and its Alloys: A Review
Authors: Ranjan Rajeev , Kumar Das Anil Kumar Das
Published: March 2023

Because of inadequate hardness, low resistance to wear, and excess friction coefficient of titanium, and its alloys are limited in their applicability. Cladding, a type of surface modification process, is used to create layers on titanium and its alloys that have superior mechanical qualities, wear characteristics, oxidation resistance at high temperatures, and good biocompatibility. Material selection is critical for achieving the increased qualities mentioned above, in addition to various cladding techniques and associated process parameters. A review of the outcomes of various common wear-resistant cladding techniques applied to the titanium alloy surface is the subject of this study. The most important functional claddings in this domain are also presented and investigated in depth. The present issues and future initiatives are also discussed, with an emphasis on identifying knowledge and technological gaps as well as attempting to establish future research possibilities. On this foundation, it is suggested that in the coming years, resistant-to-wear cladding with significant improvements in toughness and hardness should progress on the path of smart manufacturing techniques, optimising and precisely customising microstructural configurations, and developing numerical simulation techniques of cladding.

Published: March 2023

A very uncommon benign synovial membrane tumor is called lipoma arborescens. It often affects a single articulation, the knee. Despite a conventional imaging assessment, the lesion’s histological analysis is still required for the ultimate diagnosis. A 15-year-old boy attended the outpatient clinic of the Lahore General Hospital Lahore, Pakistan with pain and swelling in his left knee that had been steadily worsening over the previous 4 years. There were no concomitant prodromal symptoms, and the swelling was soft and non-tender while also inhibiting knee flexion. Soft tissue shadows were observed on radiographs. A large amount of subarticular erosion in the nearby tibial and femoral condyle was caused by the frond-like proliferation of fatty synovium, according to magnetic resonance imaging. Only the left knee joint showed focused areas of unusually elevated radionuclide uptake during the Technetium (Tc99m) bone scan. After an open synovectomy, the specimen underwent histological analysis, which revealed villiform fatty tissue, a hallmark of Lipoma arborescens coated by somewhat thicker synovium. Although infrequent, open synovectomy is currently the preferred course of treatment for lipoma arborescens, which should be taken into account when making a differential diagnosis of knee diseases. Approximately 3 months after surgery, the patient underwent his most recent follow-up and was asymptomatic with a small amount of joint effusion.

Labuan Bajo as a super priority, world class and super premium destination, has tourism differentiation compared to other tourist destinations, so that it attracts foreign tourists to visit. However, for backpacker tourists, seeking integrated information related to traveling to Labuan Bajo is one of the obstacles in the pre-trip process. Backpackers have to compare the cheapest prices from one application to another, so they experience difficulties in organizing trips manually. This resulted in the pre-trip process being inefficient and ineffective. Based on this description, this study aims to identify the need for backpacker travel guides to facilitate the pre-trip process effectively and efficiently. The research was conducted using a qualitative approach through distributing questionnaires, in-depth interviews, comparative studies, and literature studies. The results of filling out the questionnaire by the respondents were then analyzed using a quantitative approach. The results of the analysis state that Indonesia has many popular travel applications, but none yet accommodate backpacker problems, so a special backpacker travel application is needed to make the travel process efficient and effective.Keywords: mobile travel application, backpacker, Labuan Bajo, organise effective and efficient travel
