As a key aspect of product development, usability of a product is needed to be assessed by conducting usability evaluation. Within the usability evaluation methods, there are several usability assessment questionnaires; one of the most commonly used is the System Usability Scale (SUS). However, the SUS is originally developed in English and there had not been any study conducted to develop the Indonesian version of SUS. The adapted version is expected to help usability researchers and practitioners in Indonesia while conducting usability product evaluation. Therefore, this study was carried out to adapt the original SUS into the Indonesian version by using cross-cultural adaptation and reliability test. The Cronbach's Alpha of the Indonesian adaptation of SUS was 0.841, which concludes that this version is reliable to be used by usability practitioners.

Due to the COVID-19 pandemic, most educational institutions across the world have shifted their teaching and learning processes and put efforts into preparing online distance education to ensure education continues uninterrupted. Some did not face difficult tasks or challenges during this process because they were already implementing online or blended learning before the pandemic. However, some institutions, lecturers and students were not ready to adapt to the conditions, and it is therefore important to examine to what extent lecturers are ready to teach online. This research aims to evaluate the readiness of lecturers during a pandemic that arises unexpectedly. It also aims to investigate the weaknesses and obstacles that lecturers must overcome in order to teach an online class. This research applies a mixed-method approach. Lecturers were surveyed through online preparedness questionnaires, and several themes were constructed from the gathered qualitative data. The results show that lecturers have strong baseline technical skills to use e-learning platforms for online courses; they have quickly adapted to using a Learning Management System (LMS), and most have a tactical solution for most online classes with insufficient feasibility, but they do not have a strategic solution. Their sufficiency for teaching online courses was not optimised since they did not fully believe the learning goals could be achieved. This paper elaborates on the theoretical and practical implications.

This study proposes an integrated framework that investigates interrelationships between contextual factors that influence e-business use and consequently its impact on enterprise performance among small and medium enterprises (SMEs). This study starts with an extensive systematic review of e-business use factors that are contextualized in the technology, organization and environment (TOE) framework and conceptualized using resource-based view (RBV). Data are obtained through a survey of 325 Indonesian SMEs. The partial least square structural equation modeling technique is used to analyze the data and test the hypotheses. The organizational context emerges as the most significant predictor of e-business use, followed by technological and environmental contexts respectively. In addition, e-business use has stronger positive influence on enterprise performance at operational level, rather than managerial and strategic levels. However, e-business use's influence on performance impact at strategic level is indirect, mediating through operational and managerial levels. While the study has attempted to explain the contextual factors that influence the use of e-business as a whole, it is deficient in explaining contextual factors that influence each of e-business applications being used. This study could help SMEs identify contextual areas that may guide them to successfully use e-business and realize its potential benefits.

This paper aims to adapt and validate the User Experience Questionnaire Plus (UEQ+) in the Indonesian context. The UEQ+ is a modular extension of the User Experience Questionnaire (UEQ), which has been adapted to the Indonesian context and used in many studies. The UEQ+ was originally developed in German and English. As a modular extension, the UEQ+ has more user experience (UX) scales compared to the UEQ and can be used to evaluate products in special scenarios. Several steps were carried out to adapt and validate the UEQ+: translating the questionnaire into Bahasa by involving UX practitioners, evaluating the translation results by involving a UX expert and practitioners, and conducting face validity and reliability testing through two case studies (Zoom and Learn Quran Tajwid as online learning tools). The results showed that the findings from the open-ended questionnaire were consistent with the results of the six scales. Future work is needed to investigate whether the UEQ+ can capture some of the UX-related themes identified from the two case studies.
