The Covid-19 outbreak has affected several aspects of field-based learning. The best way to ensure the survival and safety of everyone involved in field-based learning is to adapt and integrate technology. In response to this problem, numerous innovations in learning technology that lead to the virtualization of the learning environment have begun to emerge. However, the various application products developed have fallen short of the expectations of students. As a result, in order to design the optimal virtual application for use in field-based learning, a needs analysis must be done. This study offers an understanding of student needs for virtual field-based learning applications. An online survey of 140 active university students was carried out to do so. The results showed that students require applications with sophisticated features that resemble the real world for the implementation of online field-based learning. They expect the incorporation of online meeting features, 360 Virtual Reality Panorama, access to learning videos, augmented reality, learning materials, chatbox, and multimedia into the software that will be developed.

Various health and welfare problems in human society originate from air pollution. PMx as one of the hydrometeorological hazards caused by humans is sustainable, ironically having an impact on the lives of human society, especially in areas that are densely populated. This research aims to estimate the susceptibility of PMx air pollution in Java Island, Indonesia. This island was chosen because it has a large population (151.59 million people in 2020) and is growing into a regional economic and industrial center. Java Island also has various cases of extreme air pollution. In this study, the Analytical Hierarchy Process (AHP) method is utilized to assess the susceptibility of anthropogenic PMx air pollution, taking into account factors like morphology, rainfall, mining area buffers, industrial area buffers, and traffic buffers. The results showed that anthropogenic PMx susceptibility was related to active and passive factors. The active factor is anthropogenic activity, while the passive factor is natural inhibition. Anthropogenic activities that have a big influence are industrial activities, followed by mining activities, and transportation. Meanwhile natural inhibitors such as rainfall and morphology, have a relatively smaller influence. Analysis of susceptibility distribution is very important for mitigating air pollution hazards, especially in Java Island.

Nowadays, studying prehistoric sites in Indonesia has become convenient because of the touch of technology. We no longer need to spend money, time, and energy to visiting the sites in person. Virtual Reality (VR) is the commonly used immersive technology for virtualizing prehistoric sites. Cutting-edge research is utilizing Virtual Reality (VR) technology to construct virtual environments of prehistoric sites, allowing people to learn and enjoy them with flexibility. However, in the context of learning, its use is still quite limited due to general features. Therefore, it is necessary to develop applications with more complete and interactive learning features. The aim of this study is to develop a web-based Si-VirPraJa (Prehistoric Virtual Site) application. We employed research and development (R&D) to achieve the objectives of the research. Furthermore, we used the ADDIE development model, which includes analysis, design, development, implementation, and evaluation. We initiated the research by conducting a needs analysis study of the Si-VirPraJa App as expected by students and teachers. The needs analysis results formed the foundation for designing the application’s initial stage. Learning media experts tested it and provided assessments, suggestions, and comments. The Si-VirPraJa app, refined based on assessment results, suggestions, and comments from media experts, is implemented in a trial class to gather feedback from students and teachers. The findings suggested that students need a virtual tour-based application to study prehistoric sites in Indonesia. This necessary application must also include multiple features that facilitate learning. The findings from validation tests conducted by experts and trials class that the Si-VirPraJa application is viable for use as a learning media. The impact of using this application for learning is evident in students’ enhanced self-learning ability, improved comprehension of the material, and the generation of engaging and meaningful learning experiences.

SPADA Brightspace is an e-learning platform designed for online Teacher Professional program learning activities. This platform has become a virtual learning environment with no boundaries of space and time between educators and students for a long time. It is equipped with various learning features and learning progress recorded by the system. This paper aims to determine the effectiveness of using SPADA Brightspace in improving pedagogical skills of participants in the Teacher Professional program. This research uses a quantitative approach using One Group Pretest-Posttest Design. Also, the effectiveness was measured by the result of pre and post-test given to the participants based on several indicators such as the ability to design course plan (RPP), to compile teaching materials, to produce learning media, to create student activity sheets (LKPD), and to make evaluation instruments. By using descriptive statistical analysis, this study found that the SPADA Brightspace platform was effectively used for improving pedagogical skills of participants.
