Abstract

Drawing on an online meditation community mentored by Samanera Abhisarano in Indonesia, this study explores how the members use digital media to engage in religious practices and teachings. The data were collected through multisited digital ethnographic fieldwork conducted from December 2021 to July 2022. During this period, we immersed ourselves in the WhatsApp group and the Zoom virtual room of the community. In addition to participating in their online activities and interviewing five community members remotely, we conducted on-site fieldwork at the temple where the mentor lives and organized a face-to-face in-depth interview with him. Employing Hjarvard’s theory of mediatization of religion, we analyzed how Buddhist teaching and practices were mediatised through the intensive use of digital media in religious environments. We argue that digital media have, to some extent, transformed the routine of this community in terms of performing religious activities. The finding supports Hjarvard’s argument that mediatization of religion is a process in which the media have taken over some roles of religious authority and transformed the way society interacts with religion.

Abstract

This research explores the impact of environmental and technical factors on air-to-ground (A2G) wireless communications using drones, specifically tackling challenges like multipath propagation, Doppler effects, and geographical variability. The study aims to analyze performance determinants of A2G communications, develop a simulation model to predict communication issues and offer recommendations for optimizing interactions between drones and ground stations. The methodology includes data collection from field tests and simulations, focusing on various environmental and weather conditions. Statistical data analysis, including regression and hypothesis testing, is employed to interpret the results. Key findings reveal that factors such as operational altitude, drone speed, and weather conditions—mainly rain—significantly affect throughput, latency, and packet loss. Optimal communication performance is achieved at a drone height of 120 meters, with rural environments offering the best conditions for data transmission. Conversely, urban settings experience decreased throughput and increased latency due to physical obstructions like buildings and infrastructure. These insights highlight the need for adaptive communication technologies and comprehensive testing across diverse conditions. The research advocates further exploring advanced antenna technologies, dynamic operational adjustments informed by real-time environmental data, and robust security measures to enhance communication reliability. In conclusion, this study establishes a strong foundation for future advancements in drone communication technologies, aiming to improve the safety and efficiency of drone operations across various applications. The findings serve as a roadmap for developing innovative solutions to address the inherent challenges of A2G communications in varying operational environments.

Abstract

Versatile video coding (VVC) has a notable increase in encoding efficiency over high efficiency video coding (HEVC) but bandwidth and storage are limited in real-world video applications, so rate control is crucial. Even if VVC shows a notable increase in encoding capacity over HEVC, the rate control may create fluctuations in video quality and computational complexity. This fluctuation can have a significant impact on the watching experience, particularly in low-bitrate settings. The rate control variables of the consistent resolution and the decreased resolution are proposed in order to make the rate control method hybrid to consistent resolutions and reduce computational complexity. To achieve optimal coding parameters, the frames with varying resolutions Lagrange multiplier (λ), skip coding tree unit (CTU) and quantization parameter (QP) are combined. After evaluation, the average encoding time savings (????????????????????????????) were found to be 19.49%, with a Bjontegaard delta bit rate (BDBR) of -0.44% indicating insignificant quality loss.

Abstract

This research aims to examine the impact of halal label on buying decision that is mediated by religiosity. Previous studies on these variables did not illustrate consistent findings. Therefore, this research is done to provide more empirical evidence by studying Skin Aqua, a Japanese skincare brand in Indonesia that has recently displayed a halal label on its new packaging. Utilising a survey method, the questionnaires were distributed to 100 respondents selected by using the purposive sampling technique. The path analysis technique was used to examine the hypotheses. The result indicates that halal labels cannot directly bring a significant influence on buying decisions, but religiosity does. Moreover, religiosity may strengthen the impact of halal labels on Indonesian Muslim consumers’ buying decisions, because the effect of Halal Label to Buying Decision is more significant in an indirect manner rather than the direct one.

Abstract

Journalism is ideally a secular practice. However, there are a number of press institutions associated with religious organizations in Indonesia, such as DAAI TV, which was established by the Yayasan Buddha Tzu Chi Indonesia. This research explores the role of Buddhist religious values in shaping journalistic practices at DAAI TV. The data were gathered using the ethnographic method through participant observation, in-depth interviews, and document analyses from August 2019 to April 2020. Implementing the framework of Buddhist-oriented journalism concepts introduced by Gunaratne (2009) and Pearson and Senarath (2015), this study indicates that DAAI TV has brought the notion of Buddhist journalism to life, despite the fact that not all of its journalists are Buddhists. In terms of ethics, DAAI TV actualized Buddhist journalism by incorporating sammā-vācā (right speech), sammā-kammanta (right action), and sammā-ājiva (right livelihood) into their journalistic practice.
