The Indonesian Red Cross is responsible for the distribution of blood products to hospital blood banks. The daily blood distribution route will vary due to the fact that the number of blood requests and the number of hospital blood banks vary on a daily basis. The implementation of a cold chain system is one method of optimizing blood distribution and transportation activities. The objective of this investigation is to evaluate the temperature and quality of PRC components in relation to their delivery time and distance. This research method is quantitative-descriptive. The population of this study consisted of all blood that was donated to the hospital blood bank in Sidoarjo Regency between October and November 2022. The blood sample used in this study was collected from the UDD PMI Sidoarjo Regency. The sampling technique of accidental sampling would be employed to visually identify the quality of PRC and temperature. The results of this study indicated that 460 PRC bags were delivered to three hospital blood banks in the UDD PMI Sidoarjo Regency. The PRC did not experience lysis, and 50 bags (10.86%) of the 460 PRC bags experienced a temperature change of over 10 °C. Conclusion: The temperature of the dropped PRC components is influenced by the delivery time and distance. The SOP must be strictly adhered to by all officers who distribute and transport blood to guarantee that the quality of the blood remains in good condition.

Transmission of infectious diseases is one of the risks in the blood transfusion process. The Blood Donor Unit (UDD), as a blood provider institution, must ensure that blood products distributed in the community are safe, especially from infectious diseases that can be transmitted through blood transfusion (TTI). UDD PMI Surabaya is a first-class UDD and CPOB-certified facility that serves blood needs not only in East Java but also as a reference for the Eastern Indonesia region. The location of UDD is in a big city, the number of donors is quite large, the coverage of the area of origin of donors and the target users of blood products is quite broad, and a complete screening test method are interesting factors to study regarding the prevalence of TTI disease. This study aims to determine the prevalence of infectious diseases transmitted through blood transfusion among blood donors in UDD PMI Surabaya in 2018–2022, as well as the sociodemographic characteristics of reactive donors. This research is a retrospective, descriptive study. Data for 2018–2022 comes from the in UDD PMI Surabaya database with total number of 639580 blood donors. The research results show that hepatitis B is a TTI disease with the highest prevalence compared to other TTI diseases. Most donors come from the 17–30 year age group who have reactive TTI test results, and this decreases with increasing age except for hepatitis B. Reactive donors are more dominated by women than men, except for HIV disease.

The availability of blood with unbalanced blood needs causes blood service facilities to lack blood stock. The deferral in donating blood is one of the reasons for the shortage of blood stock. The purpose of this study was to determine the characteristics of donors who experienced deferral in donating blood due to haemoglobin levels at UDD PMI Bojonegoro Regency in 2019–2022. The research design used is descriptive-quantitative through a secondary data survey. Data was obtained from the SIMDONDAR application regarding the number and characteristics of donors who experienced deferral in donor selection due to haemoglobin levels at UDD PMI Bojonegoro Regency during the 2019–2022 period. The data were analysed descriptively and presented in the form of tables and graphs. The results showed that the delay in donor selection was due to haemoglobin levels at UDD PMI Bojonegoro Regency for the 2019–2022 period, with as many as 3,385 donors with low haemoglobin levels totaling 2,492 people and 893 people with high haemoglobin levels. Characteristics of donors who experience delays in donating blood due to haemoglobin levels at UDD PMI Bojonegoro Regency in 2019–2022, based on age: most occur at the age of 25–44 years with a total of 198 people (51%); the most gender is female with a total of 208 people (54%); blood type occurs in O (+) in 148 people (38%); and type of work occurs in private employees in 138 people (36%).

The prevalence of Hepatitis B and C remains high in Indonesia. These diseases impact health, productivity, social interactions, and financial status. Applying digital technology to prevent the spread of hepatitis B and C using the Hepatitis BC Maps application is an important innovation. The objective of this study was to compare people's knowledge of hepatitis B and C before and after receiving education via the Hepatitis BC Maps application prototype at the PMI Kediri. The research design was quasi-experimental with a time-series design for a single group. To obtain a sample of 66 people, a simple random sampling technique was used to determine the research sample. This study employed univariate descriptive analysis and the Wilcoxon signed-rank test for data analysis. Pretest and posttest questionnaires were utilized for data collection. After receiving an education using the Hepatitis BC Maps application prototype, the level of knowledge of voluntary blood donors at the PMI Kediri increased. Numerous variables, including education, information, occupation, and age influence the knowledge level. This educational feature is a visual medium that can aid in memory retention because it allows one to visualize something that is explained more concretely and realistically.
