Abstract

The COVID-19 pandemic that has been occurred since March 2020 has forced learning activities to be carried out online. Online learning activities can generally be done using a learning management system (LMS) and video conference applications. However, in some subject topics, practicum activities are needed, such as in practicum using a computer laboratory. To accomplish computer practicum activities during the pandemic, a computer laboratory that can be accessed online is required. One of the online practicum solutions is a virtual laboratory (Vlab), which is a virtual computer laboratory that uses virtualization technology. Vlab provides a virtual machine (VM) that is accessed online with a remote access application (Remote Desktop Protocol/RDP, Virtual Network Computing/VNC, Secure Shell/SSH). Vlab infrastructure can either use on-premise or public cloud infrastructure. Compared to on-premise infrastructure-based Vlab, public cloud-based Vlab does not require an expensive initial investment and eliminates routine complex hardware maintenance. This study proposes a cloud-based Vlab application with Azure Lab Services in the case of an Object-Oriented Programming class. Vlab was designed based on the technical needs of the programming practicum, which included VM specifications (CPU, RAM, and storage), operating system, and software that must be installed up to the number of VMs in one class. Based on the total cost of ownership analysis, the cost of providing cloud-based Vlab was potentially up to 26% cheaper than on-premise infrastructure-based Vlab. A cloud-based Vlab installation performed using a Powershell script could be completed in six interactions and an installation time of 132 minutes. Vlab access could be done with a standard computer/laptop with an internet connection and an RDP client application. The bandwidth required to access a cloud-based Vlab ranged from 0.13 Mbps to 3.09 Mbps. The bandwidth range is still within the average speed range of the 4G networks available in Indonesia.

Abstract

The system implementation within the company or organization is accompanied by the redesign of business processes and changes in organizational structure that are carried out to align system implementation with business strategies. In a mandatory environment,, the decision to adopt technology is determined by the management so that in the end employees will use the technology. However, there is a possibility that the employee may engage in destructive behavior so that failing to implement innovations or technology. Many studies have developed models that can be used to measure the success of mandatory system implementation and identified the factors that influence that success. The purpose of this literature review is to provide a comprehensive summary of research related to the success model of mandatory system implementation, provide insight into the critical success factors of mandatory system implementation, and identify research limitations in the literature to provide possible future. The research selected in this literature review is research from 2016 to 2021.

Abstract

E-commerce can be used to increase companies or sellers’ profits. For consumers, e-commerce can help them shop faster. The weakness of e-commerce is that there is too much product information presented in the catalog which in turn makes consumers confused. The solution is by providing product recommendations. As the development of sensor technology, eye tracker can capture user attention when shopping. The user attention was used as data of consumer interest in the product in the form of fixation duration following the Bojko taxonomy. The fixation duration data was processed into product purchase prediction data to know consumers’ desire to buy the products by using Chandon method. Both data could be used as variables to make product recommendations based on eye tracking data. The implementation of the product recommendations based on eye tracking data was an eye tracking experiment at selvahouse.com which sells hijab and women modest wear. The result was a list of products that have similarities to other products. The product recommendation method used was item-to-item collaborative filtering. The novelty of this research is the use of eye tracking data, namely the fixation duration and product purchase prediction data as variables for product recommendations. Product recommendation that produced by eye tracking data can be solution of product recommendation’s problems, namely sparsity and cold start.

Abstract

MOOC (Massive Open Online Course) is an innovation in the field of online learning that has been popular since 2012. MOOC users during the COVID-19 pandemic increased dramatically, but the dropout rate for MOOC was also high. One of the things that causes the high dropout rate is the MOOC design. To get a good MOOC design, it is necessary to design an instructional design. Instructional design is a guide in designing instruction or learning stages to facilitate effective learning so that learning objectives can be achieved. Many examples of instructional design have been introduced in previous studies, one of which is "The 7Cs Learning Design Framework". In this research, a mapping of elements that are found in MOOC will be carried out into the category of MOOC features that are closely related because of the similarity of functions and properties with "The 7Cs Learning Design Framework". It is hoped that after this mapping has been carried out, system developers and MOOC instructors can focus more on a good MOOC design so as to maintain MOOC user retention and satisfaction.

Abstract

Indonesian society is undergoing a shift of behavioral patterns towards the coronavirus (COVID) 19 indicating the symptoms of the pandemic fatigue phenomenon. Pandemic fatigue is defined as a gradual demotivation to adhere to recommended protective behaviors. Pandemic fatigue might reduce the effectiveness of health protocols and accelerate the spread of the virus. This study aims to examine the pandemic fatigue sentiment of Indonesian twitter-users chronologically and the factors causing the development of pandemic fatigue sentiment. The method of this study includes digital ethnographic theory using sentiment analysis based on the Valence Aware Dictionary for Sentiment Reasoning (VADER) algorithm and topic modelling using Latent Dirichlet Allocation (LDA) analysis. The results showed a pattern of sentiment degression towards health protocols indicating the pandemic fatigue phenomenon. The factors causing the sentiment degression were influenced by three themes: (1) public criticism of the government's efforts to handle the spread of COVID-19, (2) experience in implementing health protocols, and (3) statements that against the government’s efforts to handle the spread of COVID-19. Based on the results of sentiment analysis and topic modelling, this study presents a public policy design referencing the World Health Organization (WHO) framework for community reinvigoration in the midst of pandemic fatigue that could be used for the government to undertake broader reforms to public health and social care for Indonesian society.

Abstract

E-learning mulai diterapkan di Universitas Mercu Buana Yogyakarta (UMBY) yang diawali dari Fakultas Teknologi Informasi pada tahun 2009. Selanjutnya diberlakukan diseluruh fakultas yang ada. Sistem e-learning yang telah diimplementasikan adalah Learning Management System (LMS) berbasis web yang dikembangkan secara mandiri (custom development). Sejak implementasi dilakukan, belum pernah dilakukan studi formal mengenai kesiapan (readiness) sumber daya (mahasiswa, dosen, dan staf) yang terlibat, sehingga belum diketahui sampai sejauh mana pendayagunaan e-learning di UMBY. Oleh karena itu, perlu dilakukan evaluasi terhadap sistem e-learning yang digunakan, untuk mendapatkan rekomendasi guna pengembangan e-learning selanjutnya. Instrumen yang digunakan dikembangkan dari instrumen Aydin dan Tasci; Kapp; Watkins, Leigh, dan Trainer; dan Haney yang disesuiakan dengan kondisi yang ada di UMBY. Instrumen yang dihasilkan terbagi menjadi lima faktor yaitu teknologi, inovasi, pengembangan diri, dan konten dengan mempertimbangkan konstruksi sumber daya, keterampilan, dan sikap pada masing-masing faktor. Selanjutnya instrumen tersebut dikelompokkan berdasarkan tiga komponen yaitu proses, produk, dan orang. Setelah dilakukan uji validitas dan reliabilitas terhadap item-item disetiap faktor model e-learning readiness (ELR) yang diusulkan, model tersebut diimplementasikan di UMBY. Secara umum model tersebut dapat diterima dan dapat digunakan untuk memperoleh gambaran menyeluruh mengenai implementasi e-learning. Model ini dapat diuji untuk diterapkan pada institusi pendidikan yang lain walaupun dengan kondisi e-learning yang tidak persis sama. Hasil survei menunjukkan bahwa UMBY sudah siap untuk melaksanakan e-learning, tetapi dengan beberapa perbaikan pada masing-masing faktor. Dengan kondisi tersebut menunjukkan bahwa sistem e-learning di UMBY belum perlu dilakukan reengineering.

Abstract

The ACM/IEEE Computing Curricula 2020 includes the study of relational databases in four of its six disciplines. However, a domain ontology model of multidisciplinary database course does not exist. Therefore, the current study aims to build a domain ontology model for the multidisciplinary database course. The research process comprises three phases: a review of database course contents based on the ACM/IEEE Computing Curricula 2020, a literature review of relevant domain ontology models, and a design research phase using the NeOn methodology framework. The ontology building involves the ontology reuse and reengineering of existing models, along with the construction of some classes from a non-ontological resource. The approach to ontology reuse and reengineering demonstrates ontology reusability. The final domain ontology model is then evaluated using two ontology syntactic metrics: Relationship Richness and Information Richness. These metrics reflect the diversity of relationships and the breadth of knowledge in the model, respectively. In conclusion, the current research contributes to the Computing Curricula by providing an ontology model for a multidisciplinary database course. The model, developed through ontology reuse and reengineering and the integration of non-ontological resources, exhibits more diverse relationships and represents a broader range of knowledge.

Abstract

Trust is described in various contexts, such as e-commerce, e-government, reviews, and online health information. Credibility and information quality are fundamental to building trust in those contexts. This study aimed to develop trust perception (TP) and information use (IU) indicators in an information evaluation context. Indicators were developed through three processes: searching, grouping, and construction. Relevant indicators were grouped based on similarities to construct statements, which were validated for face and content validity by three experts. The validated TP and IU were then tested using the partial least squares structural equation modeling (PLS)-SEM. The data used for measurement obtained from 110 participants comprising 55 Indonesian academic librarians and 55 university students. Participants responded to indicator statements after evaluating information from four prepared informational websites. This study yielded five TP indicators and a single IU indicator, where TP significantly predicted IU. The five indicators described TP as make-sense information relevant to needs, provided by trusted authors and providers, and accompanied by accessible author information, provider information, and reference sources. IU was described as the information used for its credibility. The measurement demonstrated distinct participant behaviors. Differences in needs influenced assessments, while author and provider trustworthiness showed no bias toward participant type. Trust perception significantly predicted IU, with moderate model fit and varying predictive strengths across the websites. Tested as reliable, valid, and a significant predictor of IU, TP serves as a tool for examining factors that potentially influence trust in online information.
