Soil Quality and the Selection of Physicochemical Properties around Maro Rivers in Merauke Papua
Bibliographic record
Abstract
Merauke Regency has 216.196 Ha of mangroves area which most of it was fed by the Maro River. The purpose of this research was to study the chemical, nutrient movement, and physiochemical properties by collecting the soil around the Maro River. 10 collected soil samples (0-20 cm depth) were analyzed using standard methods. The result showed that the average CEC of soils around River Maro is 15.95 cmol/kg. Organic matter and soil moisture content could be the contributor to enhance the CEC of soil. The average organic carbon was 1.34%, while the BOD and COD were 2.44 and 5.70 mg/L. Soil could have different mineralogical content which nutrient around Maro is decreasing due to waste disposal to the river, agricultural practice, and other human activities. Environmental management needs to reevaluate and studies about soil mineralogy strongly recommended.

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.
