Abstract
Nowadays, Twitter is used as an Early Warning System (EWS) for disasters because of the speed and many users. Based on Asosiasi Penyedia Jasa Internet Indonesia (APJII) data, in 2017, almost 50% of internet users in Indonesia are born in 1983-1998. They are called the millennial generation. Therefore, this study aims to explore the trust of millennials towards Twitter as an EWS. This study utilizes the conceptual model from System Dynamics named Causal Loop Diagram (CLD) to identify the factors and the causal relationship among millennials' factors to trust Twitter as an EWS. It involves ten participants from the millennial generation, consisting of five passive Twitter users and five active Twitter users. A semi-structured interview was conducted with all participants to build the initial CLD gathered from each participant's perspective. Afterward, the initial CLD was verified by all participants through Focus Group Discussion. A group model building CLD that represents the influencing factors and their causal relationship of millennial generation trust in Twitter as EWS for a natural disaster is successfully developed from this study. The tweet frequency, the number of followers, the account credibility, the verified account, the level of trust in social media, and the content quality are considered the underlying factors of active and passive users to trust in Twitter as an EWS natural disaster.
Highlights
Indonesia is a country that regularly faces natural disasters, including tsunami and earthquakes
Passive users are more active in using other social media, such as Instagram, because the content is more attractive by showing images and videos (P4 and P5)
This paper presented Causal Loop Diagram (CLD) constructed based on the similarities and differences of passive and active Twitter users’ responses
Summary
Indonesia is a country that regularly faces natural disasters, including tsunami and earthquakes. In 2018, there were 23 earthquake cases, and one tsunami case occurred, and more than ten million people were affected [1]. Many natural disaster casualties insist that the government find a proper early warning system (EWS). This system is supposed to minimize the number of casualties and ensure the residents can evacuate early and quickly. One of the EWS commonly used in Indonesia is inaTEWS (Indonesia Tsunami Early Warning System). The inaTEWS increases the awareness and prepa-redness of the residents in facing the potential and dangers of natural disasters. The improved awareness and preparedness can contribute to minimizing the number of casualties by providing information through electronic media, brochures, posters, and other media
