Phytochemical Screening and Larvicidal Activity of Kebiul (Caesalpinia Bonduc. L) Seed Kernel Against Aedes Aegypti Mosquito
Bibliographic record
Abstract
Dengue Hemorrhagic Fever (DHF) is caused by an infected A. aegypti mosquito, which can cause serious bleeding, a sudden drop in blood pressure and even death. Kebiul seed kernel extract is thought to contain flavonoid compounds, terpenoids, saponins and steroids that can be used as larvicides. The purpose of this study was to determine the toxicity of the extract, n-hexane fraction, and ethanol fraction of kernel seed (C. bonduc. L) against A. aegypti mosquito larvae. This study used the methods of extraction, phytochemical screening, and toxicity tests by calculating larval mortality. Based on the results of phytochemical screening, extract of kernel seed (C. bonduc. L) contains tannins, flavonoids, alkaloids, steroidal saponins and terpenoids. Toxicity test (LC50 values) of extract, n-hexane fraction, and ethanol fraction of kernel seed (C. bonduc. L) are 368,566 g/mL, 483,010 g/mL, 338,361 g/mL. The LC50 value < 1000 ppm has a toxic effect, so the kernel seed has the potential to be used as a larvicide.

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.
