Stability Modeling of Groyne-Type Structure with Embankment in Pelangai River, Pesisir Selatan Regency, West Sumatra
Bibliographic record
Abstract
Erosion is one of the exogenic processes that commonly occur around river dynamics. Intensive erosion occurs at the riverbank area, which has the potential to cause the slope on that side to collapse. Therefore, a groyne-type structure is required to prevent this from happening. A groyne-type structure is planned to reduce the impact of erosion in the Pelangai River with embankment. This research aims to determine the stability of the groyne with embankment design using Plaxis 2D software. Plaxis 2D modeling uses soil input parameters based on CPT, SPT, and groyne structure with approximation parameters. The modeling results show that with the addition of groyne, embankment and traffic load, the safety number drops from 1.906 to 1.241. This figure does not meet the safe number limit according to SNI Geotechnical 8460 of 2017, which requires a minimum safe number of 1.25. In addition, the addition of groyne, embankment, and traffic load resulted in soil settlement of up to 6.3 cm, which is still considered safe.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
