Agile-Waterfall hybrid for prevention information system of dengue viral infections: A case study in Health Department of Jember, East Java, Indonesia

Dengue viral infections are one the most important mosquito-borne diseases that have rapidly spread in all regions of Indonesia including at district of Jember, East Java in recent years. They may be asymptomatic or may give rise to undifferentiated fever, dengue fever (DF), dengue haemorrhagic fever (DHF), or dengue shock syndrome (DSS). The number of dengue cases at Jember reported increased from 77 in 2011 to 923 in 2015 and case fatality rate exceeded 1.3 in 2011 and over 1.6 in 2015. The main obstacles of dengue surveillance are occurred due to lack of public response to the onset of dengue viral infections cases in the surrounding environment, reporting cases from the hospitals, clinics, or community health centre have been delayed because of accessibility factor and manual written report. Without the validity of the information from dengue patient data, epidemiological investigation can't provide valuable information to control ongoing outbreaks. To overcome these problems, the development of prevention information system of dengue viral infections plays crucial role in the identifying cases and obtaining information from them to decide what actions must be taken by Health Department of Jember to control and eliminate outbreaks. To build robust prevention information system is used the hybrid model to combine both Waterfall and Agile. Leveraging both the Waterfall and Agile approach ensures the success of the project. It removes the disadvantages of both the models while bringing together the advantages of both. The objective of this paper is to highlight the importance of the hybrid model to successfully develop and implement prevention information system of dengue viral infections at Jember to restrict mosquito-borne spreading.
