Reducing Water Absorption and Increasing the Density of Kapok (Ceiba pentandra, L.) Fibers from Kapok Production Center in Indonesia
Bibliographic record
Abstract
This research reports the reduction of water absorption and density increase of kapok fibers from production centers in Pati, Indonesia.Kapok fiber was treated with two solvents, hexane and NaOH solution at room temperature.The NaOH solution was used in five different concentrations; 3.5, 7, 10.5, 14, and 17.5%.Fiber morphology, water absorption, density, and weight loss were determined.Results indicated that the average diameter and fiber length obtained was 70.97 µm and 2.3 cm, while its cellulose and lignin contents were 55.69% and 20.56%, respectively.Furthermore, there was no significant difference between treating kapok fiber with hexane and with NaOH solution.The 17.5% NaOH solution treatment reduced water absorption, increased density, and reduced weight losses by 55.98%, 255.55%, and 25.58%, respectively.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
