Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Indonesia Ranking is primarily derived from comprehensive bibliometric data collected from OpenAlex and CrossRef, supplemented by multiple other authoritative data sources. The bibliometric data underpinning the citation-based metrics used in the ranking were compiled on January 12, 2026. A scientist's position in the ranking is determined based on their D-index (Discipline H-index), a refined metric which exclusively includes papers and citation metrics pertinent to the examined discipline of Engineering and Technology. This approach ensures that the ranking reflects specialized scholarly impact within the specified field rather than general research output.
Scope of Research and Qualification Criteria
The ranking assesses a total of 279,971 scientist profiles identified from diverse bibliometric sources across all academic disciplines, including two scientists specifically focused on Engineering and Technology. To qualify for inclusion in this specialized ranking, a scientist must have achieved a minimum D-index of 30. Additionally, a majority of their tier publications must be in the area of Engineering and Technology, thus emphasizing concentration and expertise within the discipline. Notably, scientists’ awards and notable achievements within the field were also taken into consideration during evaluation.
The threshold for the D-index is incrementally adjusted by 10 points relative to the estimated total number of scholars in each discipline, ensuring inclusion of the top 1% of leading scholars in Engineering and Technology. To maintain disciplinary relevance and consistency, there is a requirement for the D-index to be within 30% or less proximity of the scientist's overall general H-index, thereby ensuring harmonization between their general impact and discipline-specific influence.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot fully encapsulate scholarly output, the researchers responsible for this ranking implemented extensive manual verification procedures. Every scientist profile was carefully cross-referenced against publications in a broad range of trustworthy and reputable sources to validate accuracy and eliminate discrepancies.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it constitutes a valuable secondary signal confirming a scientist’s contributions to the field of Engineering and Technology. Ultimately, the position in the ranking is determined by the D-index calculated from information reliably gathered from OpenAlex and CrossRef, two of the most prominent and respected bibliometric databases accessible to the global research community.
