Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Perairan Biringkassi, Kecamatan Bungoro, Kabupaten Pangkep, Sulawesi Selatan beresiko terpolusi Pb dari kegiatan bongkar-muat batubara di Pelabuhan Biringkassi dan penangkapan ikan menggunakan perahu berbahan bakar bensin. Penelitian ini bertujuan untuk mengetahui apakah sedimen dan udang windu di perairan ini telah terpolusi logam Pb. Sampel diambil di perairan sekitar Pelabuhan Biringkassi dan di sekitar pulau Camba-cambayya yang berjarak 7 km ke arah barat Pelabuhan Biringkassi dan relatif masih jauh dari keramaian kegiatan manusia. Pengukuran kadar Pb menggunakan metode spektroskopi serapan atom di laboratorium yang telah terakreditasi di Makassar. Konsentrasi Pb di sedimen perairan Biringkassi adalah 47,33 ± 11,34 mg/kg dan di sedimen perairan Pulau Camba-cambayya adalah 28,23 ± 5,17 mg/kg. Konsentrasi Pb udang windu yang ditangkap di perairan Biringkassi adalah 2,19 ± 0,98 mg/kg sedangkan yang ditangkap di sekitar Pulau Camba-cambayya adalah 0,54 ± 0,21 mg/kg. Student T-test yang digunakan untuk menentukan apakah sampel telah terpolusi logam Pb (melewati ambang batas 30,2 mg/kg untuk sedimen [Canadian Council of Ministers of the Environment, 1999] dan 0,5 mg/kg menurut Badan Pengawasan Obat dan Makanan Republik Indonesia) menunjukkan sedimen dan udang windu dari perairan Biringkassi telah terpolusi logam Pb. Kata kunci: Sedimen, Udang windu, Pb, SSA

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
