Development of the Hub and Spoke network model in natural disaster management

Indonesia is a country with high disaster vulnerability. Disasters have a huge impact on a nation's economic development. According to the National Agency for Disaster Management, a disaster is an event or a series of events that threatens and disrupts the lives and livelihoods of people, caused by either natural factors and/or non-natural factors, as well as human factors and resulting in human casualties to lead. Environmental damage, property damage and psychological impact. This study is limited to hazards caused by natural factors, including nine types of threats, namely: earthquakes, tsunamis, volcanic eruptions, landslides, floods, flash floods, drought, forest and land fires, and extreme waves and abrasion. As an archipelago country, Indonesia has challenges in disaster management. Another thing behind this study is that there is a discrepancy between disaster maps and the location (distribution) of ships that have the potential to be deployed in disaster management, which will affect the duration of the emergency response time and the high cost of disaster management. What's more, there are conditions in which ships cannot perform certain coping functions, affecting the inability to effectively treat disaster victims, potentially increasing fatalities. Not all ships are suitable for disaster response operations in specific areas, resulting in the emergency response time being too long and the cost of disaster response being high. The purpose of this study is to evaluate the effectiveness of the existing ship distribution state that can be used in disaster management versus the existing disaster map. The research method used is to collect data and identify potential disasters in Indonesia. Then collect data and map the type and number of ships and the distribution of ship bases that can be used in disaster management. Using qualitative analysis, assess the discrepancy between vessel availability and distribution and the potential location and nature of the disaster in Indonesia. The expected result is that there is a match between the availability and distribution of vessels and the potential of the location and nature of the disaster in Indonesia.
