The Cyclone of Senyar that happened at the end of November 2025 was one of the extreme weathers due to the climate change. Three provinces in Indonesia were affected, but the one with the highest impact was Aceh Province. In October 2025, the rainfall in most area in Aceh Province of Indonesia was considered as medium, around 100 – 300 mm/ month.1 But during the Cyclone, the rainfall was increased up to almost 400 mm/ day,2 which is considered as extremely heavy rain and caused big flood and Landslides resulted in road closures.1
This disaster had an impact on blood services in Aceh province so Central Blood Centre of Indonesian Red Cross coordinated other blood centres in Java Island which had enough blood stocks to be sent to Aceh province. Around 2,950 blood bags were sent to Aceh Province to supply the demand of Red Cells transfusion in Aceh Province.
Key lessons learned from Sumatra Disaster 2025 were:
1.The need of Blood Establishment self-assessment during the disaster
The blood establishment should do self-assessment including the condition of the affected blood establishment, the surrounding area and the capacity of blood establishment after disaster. During the Sumatra Disaster, communication and transportation were disrupted so it blood collections activity. From self-assessment analysis, the blood establishment in the districts, provinces and head-quarter could decide the emergency status, disaster scale and operational responsibility. In terms of determining the scale of a disaster, there should be a provision that could be reference for blood establishment.
2. The need of national or regional level coordination.
Even at all levels, every blood establishment must be able to play a role in implementing emergency disaster response services quickly and accurately, but it should be coordinated. There should be a matrix that showed responsibilities at each level based on the disaster scale. The coordination not only internal Indonesian Red Cross but also with other stake holders relevant to support blood establishments. For example, during the Sumatra disaster, one of the big supports was the help of Indonesian Air Force for transporting the blood from Jakarta to Aceh province.
3. The need of reporting system.
The blood demand, the blood stock availability in other blood centers were important information that must be available and analyzed daily during Sumatera disaster. The limited frequency and capacity of flight to Aceh province was also factor needed to be considered. Based on the analysis, it should be sent daily because there were 12 blood establishments and hospitals in the affected area but unfortunately the number of blood bags that can be supplied was limited due to the long holidays and also because the blood establishments in other areas had to be prepared for the fasting month.
We also need the usage report from hospitals to get the real demands but at the moment, we could not get the data. We heard that two patients needed massive transfusion during the disaster. We hope they got the appropriate transfusion.
The supporting system for reporting should be prepared in the disaster. But if no electricity and if all the computers were damaged during the disaster, manual reporting was the alternative method that should be conducted. Other point from reporting system was level of reporting system, to whom the data should be sent to. It may differ based on the emergency status and disaster scale.
4. The need of alternative transportation method. The headquarter of Indonesian Red Cross lies in Jakarta. We sent the blood to Aceh using Hercules plane from Indonesian Air Force based on their schedule. Sometimes, it was late at night so we had to keep the blood at Aceh Blood Center before it was sent to other remote blood center in Aceh province. Team of Aceh Blood Center also had to repack the blood in the cold-box and change the ice-pack to maintain the suitable temperature during transportation.
Other congestion during transportation when many bridges were damaged, so we had to use raft boats to cross the rivers with swift water flow. From this scenario, we should consider other methods of transportation that was safe in the future such as drones. Validation of transportation was crucial and shared to blood centers.

5. The need of disaster preparedness program training
The disaster preparedness program and guideline have to be part of trainings for all the blood establishment staff. During the Sumatra Disaster 2025, the staff dedicated for helping the disaster was also limited. Because the blood was sent according to the daily need, there were some people had to work over time on daily basis. The same level of knowledge and skills of disaster management are needed to make sure that the help successful even if one person had to take a rest and had to be changed by other.
In the end, even after the experience, Indonesia still need to learn a lot about blood donation disaster management, especially about the systems needed. Learning from other countries may help in improving the way of preparing and handling the disaster, especially about the risk mitigation strategies. Focus Group Discussion may be needed to establish a Disaster Management Guideline that covers the preparation and handling in each stage of disaster.
