Cost analysis of repairing damage to coastal protection structures in Pariaman City, West Sumatra
Bibliographic record
Abstract
Pariaman City is in West Sumatra Province, with a land area of 73.36 km² and a coastline length of 12.7 km. The local government has constructed coastal protection structures such as groins, jetties, and revetments to safeguard the shoreline and preserve the coastal ecosystem from damage caused by waves, abrasion, accretion, and erosion. Over time, several components of the groin, jetty, and revetment structures have experienced deterioration, necessitating repair. This study aims to identify the damage to each structure, propose appropriate repair solutions, and estimate the repair cost budget.The assessment of damage, repair guidelines, and prioritization of interventions are carried out based on the Regulation of the Minister of Public Works No. 09/PRT/M/2010 and the Circular Letter of the Minister of Public Works No. 01/SE/M/2011. This study found that the primary cause of damage was the disintegration of the rubble arrangements in several sections. The recommended repair solution involves adding new rocks and rearranging existing ones to interlock securely. The estimated cost of repairs is IDR 662,014,140.00.

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.
