An Evaluation on Compost Quality Produced in UTP Campus
Bibliographic record
Abstract
UTP is producing compost or organic fertilizer from the food waste that generated by cafeterias in UTP. A few tests have to be carried out to analyze the content of the compost and to determine the quality of the compost, whether it is suitable and safe to be used as fertilizer. Compost quality standard documents from Canada and United States are the main references in determining the quality of compost produced in UTP. There are 6 criteria that being considered in determining the quality of compost produced in UTP which are maturity of the compost, heavy metal content, foreign matter content, pathogens content, constituents of the compost which indicates the percent ofCHNS, NPK (Nitrogen, Phosphorus, Potassium) content of the compost and moisture content. Maturity of compost is determined based on the germination of radish seeds and bean sprout seeds in the compost and C/N ratio of the compost. Germination of those two types of seeds is carried out in three different conditions which are in 100 % soil, 1 00 % compost and in 50 % soil and 50 % compost. The content of seven types of heavy metal which are lead, cadmium, copper, chromium, zinc, nickel and boron were tested on the compost. Any matters that are greater than 2 mm in dimension that results from human intervention and having organic or inorganic constituents such as metal, glass and synthetic polymers (plastic, rubber) are considered as foreign matters. Quanti-Tray I 2000 are the device that being used to determine the amount of bacteria in 100 ml of compost sample using IDEXX-d substrate reagent. NPK content is determined by carrying out powder pillow test. Moisture content of the compost is determined using the moisture analyzer. For maturity aspect, germination of both types of seeds only occurred in 100% soil. C/N ratio of the compost is 17.67. The content of heavy metal in the compost are within the allowable limit. For foreign matter analysis, compost produced in UTP contains no man-made foreign matter such as glass, plastic, metal and stones. For pathogens analysis, the compost does not contain E.coli. The amount ofNPK in compost produced in UTP is low compared to the standard and moisture content of the compost is 54.65 %.

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.
