Volunteer altruistic behaviour in terms of disaster threat type

The altruistic behaviour of community-based volunteers in disaster situations determines the success rate of rescue achievements. The purpose of this study is to determine whether there are differences in the altruistic behaviour of volunteers in different types of disaster event threats, namely, landslides, volcanic eruptions, droughts and tsunamis in Yogyakarta. A quantitative study was conducted to answer the research question. The study involved 292 disaster volunteer participants, using the survey method. Hypothesis testing in this study used statistical methods in the form of one-way analysis of variance (ANOVA). The scores used were factor scores obtained from the results of confirmatory factor analysis (CFA) analysis. The data were analysed using jamovi software version 2.3.18. The results of the one-way ANOVA analysis showed no difference in altruism in the types of disaster threats of landslides, volcanic eruptions, droughts and tsunamis in Yogyakarta. CONTRIBUTION: The results of this study can be considered as supporting information in developing programmes by supporting the altruistic behaviour of community-based disaster volunteers. The sincerity of community-based disaster volunteers in the form of altruistic behaviour is not influenced by the type of disaster threat. One form of collective altruistic behaviour that is important and prominent in Indonesian culture is gotong royong. Gotong royong is a joint activity of helping each other without being paid, which is local wisdom in Indonesia. It is therefore important for policymakers to preserve local wisdom values such as gotong royong in disaster risk reduction programmes across different types of disaster threats.
