Abstract
Telah dilakukan penelitian tentang toksisitas Cu(II) terhadap Chaetoceros sp. dan pengaruhnya terhadap klorofil-a. Penelitian ini dilakukan untuk mengetahui nilai IC50 Cu(II) terhadap mikroalga Chaetoceros sp., pengaruh paparan Cu(II) terhadap pertumbuhan dan perubahan morfologi sel, serta pengaruh logam tersebut terhadap kandungan klorofil-a. Penelitian ini dilaksanakan melalui beberapa tahap meliputi uji toksisitas Cu(II) yang didasarkan pada metode standar Asean Canada Cooperative Program on Marine Science (ACCPMS), analisis respon morfologi dengan foto mikroskop dan uji klorofil-a dengan Fluorometer Turner Trilogy tipe AU-10. Nilai IC50 Cu(II) terhadap mikroalga Chaetoceros sp. yang didapatkan sebesar 30,25 ug L-1. Pertumbuhan mikroalga Chaetoceros sp. akan terhambat dengan adanya Cu(II). Besarnya penghambatan pertumbuhan sel naik seiring dengan bertambahnya konsentrasi Cu(II) yang dipaparkan. Pemaparan Cu(II) mengakibatkan deformasi dinding sel mikroalga dan hilangnya setae. Kandungan klorofil-a mikroalga Chaetoceros sp. menurun seiring dengan kenaikan konsentrasi Cu(II) yang dipaparkan. A research on the Cu(II) toxicity to Chaetoceros sp. and its effect on chlorophyll-a had been conducted. This research was conducted to find out IC50 value of Cu(II) on Chaetocheros sp., the exposure effect of Cu(II) on the growth and the morphology respons of its cells, and to find out the toxicant effect on the amount of chlorophyll-a. This research was conducted through several steps i.e: Cu(II) toxicity test based on standard method from Asean Canada Cooperative Program on Marine Science (ACCPMS), photo microscopic was used to see the morphology respons and chlorophyll-a test using Flourometer Turner Trilogy type AU-10. The result showed that IC50 of Cu(II) on the microalgae Chaetoceros sp. is 30.25 ug L-1. The exposure of Cu(II) hampered the growth of microalgae Chaetoceros sp. The increasing of inhbition cell is proportional with the increasing of Cu(II) concentration. The exposure of Cu(II) caused deformation on the microalgae cell wall and caused the setae to sheer off. The amount of chlorophyll-a microalgae Chaetoceros sp. decreases as the exposed concentration of Cu(II) is raised.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
