Water-Quality Assessment of the Langat River at Kilometre 7, Jalan Kajang-Bangi, Selangor, Malaysia
Bibliographic record
Abstract
The Langat River is one of the main sources of water supply for the Selangor area. For water-quality analysis, water sampling was carried out at five stations during the wet (November 2009) and dry (February 2010) seasons. These five stations are located along the river, with the exception of station 3. Station 1 and station 2 are located upstream station 3, while station 4 and station 5 lie downstream of station 3. Station 3 differs from the other four stations because it is a discharge from Universiti Kebangsaan Malaysia campus. This study was conducted to determine water quality as well as levels of pollution, based on the Water Quality Index (WQI) and the Malaysian Interim National Water Quality Standard (INWQS), of the Langat River at Km 7. A total of 14 water-quality parameters—temperature, pH, dissolved oxygen (DO), conductivity, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), PO4, NO3-, NH3-N, SO4, oil and grease, and E. co...

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.
