Evolving priorities in malaria research in Indonesia (2015-2025): A scoping review and bibliometric analysis

Background Malaria remains a major public health challenge in Indonesia, with transmission concentrated in several eastern regions. A systematic overview of national research activity is needed to show how scientific priorities have changed and whether the evidence base is aligned with elimination needs. Methodology/Principal findings We conducted a scoping review and bibliometric analysis of Scopus-indexed malaria publications from 2015 to 2025 following PRISMA-ScR guidance. Records were screened for an Indonesian institutional affiliation or an explicit Indonesia-specific study component. Publication trends, co-authorship, keyword networks, citation patterns, thematic evolution, and exploratory forecasts were analysed. Keyword text was represented using term frequency-inverse document frequency and grouped with K-means clustering. The initial candidate set contained 592 publications; four false-positive records were excluded, leaving 588 eligible Indonesia-related publications. Of these, 583 had an Indonesian affiliation identifiable in the exported Scopus metadata and 586 had usable keyword metadata for thematic analysis. Ten clusters were identified. Environmental and Community-Based Studies was the largest theme (110/586, 18.77%), followed by Plasmodium Species and Clinical Parasitology (85/586, 14.51%), Molecular Diagnostics (76/586, 12.97%), Treatment and Antimalarial Drugs (69/586, 11.77%), and Health Systems and Malaria Control Programs (67/586, 11.43%). Treatment-related research had the greatest total and mean citation impact. Publication output accumulated continuously without a clear plateau. Forecasts suggested the strongest continued growth in environmental and community-based research, while treatment and health-system themes were comparatively stable. Conclusions/Significance Indonesian malaria research became more diverse while retaining strong clinical and treatment foundations. Future research planning should balance biomedical priorities with environmental, community, diagnostic, and implementation research. Forecasts are exploratory and should not be interpreted as precise predictions.
