Data Sources and Citation Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Indonesia Ranking is primarily based on comprehensive bibliometric data aggregated from leading databases, including OpenAlex and CrossRef, alongside multiple other reputable data sources. The bibliometric data utilized for constructing the citation-based metrics were collected on January 12, 2026. Each scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that captures a researcher’s productivity and citation impact exclusively within the examined discipline of Materials Science. This ensures the ranking reflects scholarly output and influence specifically attributable to the field.
Scope of Research and Qualification Criteria
The ranking examines a total of 279,971 scientist profiles identified across a wide array of bibliometric data repositories, spanning all academic disciplines, with a focused analysis on 2,000 scientists specializing in Materials Science. To qualify for inclusion in this ranking, a scientist must have a D-index of at least 40, and a majority of their tier publications must be substantively within the domain of Materials Science. Additionally, researchers’ awards and notable achievements related to the field were carefully considered as supplementary factors in the evaluation process.
The threshold for the D-index is calibrated in increments of 10 relative to the estimated total number of scholars within the discipline. This approach guarantees inclusion of the top 1% of leading scientists in Materials Science. Moreover, to ensure alignment between general scholarly impact and discipline-specific performance, only those candidates with a proximity of 30% or less between their overall H-index and their D-index were considered.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully capture the complexity of scholarly contributions, extensive manual verification was performed for all scientist profiles. This verification process entailed cross-correlating publication records against an array of authoritative and trustworthy sources to validate accuracy and relevance. While the number of publications in prominent journals and conference proceedings is not a direct factor in ranking placement, it serves as a valuable complementary indicator of a scientist’s specific contributions to Materials Science research.
The final ranking positions were established using each researcher’s D-index derived from the meticulously curated data provided by OpenAlex and CrossRef, which stand as the most prominent and widely recognized bibliometric databases accessible to the global research community.
