Sumatera Institute of Technology

EXECUTIVE SUMMARY AND STRATEGIC VISION

Sumatera Institute of Technology demonstrates a generally positive scientific integrity profile, reflected in an overall score of -0.167. The institution's primary strengths lie in its robust quality control mechanisms, evidenced by very low risk levels in Retracted Output, Hyperprolific Authors, Output in Institutional Journals, and Redundant Output. These results suggest a culture that prioritizes substantive research over metric inflation. The main vulnerabilities are concentrated in a medium-risk level for the Rate of Multiple Affiliations, which deviates significantly from the national standard, alongside moderate signals in Institutional Self-Citation and publication in Discontinued Journals. According to SCImago Institutions Rankings data, the Institute's research is particularly prominent in Chemistry, where it holds a top-tier national rank (#3), with other key strengths in Engineering, Earth and Planetary Sciences, and Environmental Science. To fully realize its mission of achieving "excellence in education, research, and community service," it is crucial to address the identified integrity risks. Practices that could be perceived as inflating institutional credit, such as an unmonitored rate of multiple affiliations, may undermine the credibility of its genuine academic achievements. By reinforcing its clear strengths in research integrity and strategically managing its vulnerabilities, the Institute can ensure its operational practices fully align with its aspirational goals, solidifying its role as a leader in empowering regional and national potential.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of 2.525, while the national average is -0.674. This result indicates a moderate deviation from the national norm, suggesting the institution shows a greater sensitivity to risk factors than its peers. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, the institution's disproportionately high rate signals a potential risk. This pattern can be interpreted as a strategic attempt to inflate institutional credit or “affiliation shopping,” which warrants a review of internal policies to ensure that all declared affiliations correspond to substantive and transparent collaborations.

Rate of Retracted Output

The institution's Z-score for this indicator is -0.559, in stark contrast to the national average of 0.065, which is in the medium risk range. This demonstrates a case of preventive isolation, where the institution successfully avoids the risk dynamics related to retractions that are more prevalent at the national level. The institution's exceptionally low rate is a positive signal, suggesting that its quality control and peer review mechanisms prior to publication are robust and effective. This performance indicates a strong integrity culture that prevents the systemic failures or methodological weaknesses that often lead to a high volume of retracted work.

Rate of Institutional Self-Citation

The institution's Z-score is 0.349, while the national average is 1.821, with both falling within the medium risk category. This profile suggests a differentiated management approach, as the institution successfully moderates a risk that appears to be more common and pronounced across the country. A certain level of self-citation is natural and reflects the continuity of research lines. However, the institution's controlled rate, well below the national tendency, indicates a healthy balance, avoiding the "echo chambers" that can arise from excessive self-validation and ensuring its work is subject to sufficient external scrutiny.

Rate of Output in Discontinued Journals

The institution shows a Z-score of 0.179 (medium risk), which stands in favorable contrast to the critical national average of 3.408 (significant risk). This demonstrates a relative containment of risk; although some warning signals are present, the institution operates with considerably more order and diligence than the national trend. A high proportion of publications in discontinued journals constitutes a critical alert regarding the selection of dissemination channels. The institution's moderate score suggests that while there is room for improvement in information literacy, it is largely avoiding the systemic channeling of research into media that fail to meet international ethical or quality standards, thereby protecting its reputational integrity more effectively than its peers.

Rate of Hyper-Authored Output

The institution's Z-score for this indicator is -0.840, closely aligned with the national average of -0.938, both at a low risk level. This proximity in scores points to an incipient vulnerability, where the institution shows slightly more activity in this area than the national baseline, warranting review before it escalates. While extensive author lists are legitimate in "Big Science," their appearance in other contexts can indicate author list inflation, which dilutes individual accountability. The current low level is not alarming, but the slight upward trend compared to the country suggests a need for vigilance to distinguish between necessary massive collaboration and the emergence of "honorary" authorship practices.

Gap between Impact of total output and the impact of output with leadership

The institution has a Z-score of -0.701, which is more favorable than the national average of -0.391, both within the low-risk range. This indicates a prudent profile, where the institution manages its collaborative processes with more rigor than the national standard. A wide positive gap can signal that an institution's prestige is dependent on external partners rather than its own structural capacity. The institution's negative score is a strong positive indicator, suggesting that its scientific prestige is largely the result of real internal capacity and that it exercises intellectual leadership in its collaborations, ensuring sustainable and endogenous academic excellence.

Rate of Hyperprolific Authors

The institution's Z-score is -1.413 (very low risk), significantly below the national average of -0.484 (low risk). This demonstrates low-profile consistency, where the complete absence of risk signals at the institutional level aligns with and improves upon the national standard. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution and point to risks like coercive authorship or "salami slicing." The institution's very low score in this area is a clear strength, indicating a healthy balance between quantity and quality and a research environment that prioritizes the integrity of the scientific record over inflated productivity metrics.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution operates at a very low risk level, distinguishing itself from the national average of 0.189, which falls into the medium risk category. This is a clear case of preventive isolation, where the institution does not replicate the risk dynamics observed in its environment. Excessive dependence on in-house journals can raise conflicts of interest and lead to academic endogamy by bypassing independent external peer review. The institution's minimal reliance on its own journals is a sign of good governance, demonstrating a commitment to global visibility and competitive validation through standard external channels.

Rate of Redundant Output

The institution records a Z-score of -1.186 (very low risk), which is substantially lower than the national average of -0.207 (low risk). This result reflects low-profile consistency, as the absence of risk signals is even more pronounced than the already low national standard. Massive bibliographic overlap between publications can indicate data fragmentation or "salami slicing," a practice that artificially inflates productivity by dividing studies into minimal units. The institution's extremely low score indicates a strong focus on producing significant, coherent new knowledge rather than prioritizing publication volume, thereby upholding the integrity of the scientific evidence base.
