PERBANDINGAN UJI ANTIMIKROBA MINYAK DAN RESIDU HASIL PENGOLAHAN LIMBAH MEDIS PADAT TANPA JARUM SUNTIK PASCA STERILISASI SECARA PIROLISIS DENGAN VARIASI KATALISATOR TERHADAP BAKTERI Pseudomonas aeruginosa DAN Staphylococcus aureus

Management of medical waste in healthcare facilities is often suboptimal due to the imbalance between the quantity of medical waste generated and the capacity to manage it. Therefore, effective and safe handling of medical waste is crucial from an environmental protection perspective and for disease control and prevention efforts. Pyrolysis technology is chosen to utilize this medical waste. The pyrolysis process yields liquids and residues. These liquids can be used as a renewable energy source because plastics fundamentally originate from crude oil, allowing them to be converted back to their original form. This study employs two compounds as catalysts: Ethylene Glycol and N-Hexane. It also involves two types of bacteria: Pseudomonas aeruginosa and Staphylococcus aureus. The research reveals differences in inhibition zones observed in antimicrobial tests of oils and residues with varying catalysts for post-sterilization solid medical waste treatment on hydrocarbonoclastic bacteria The results showed that Pseudomonas aeruginosa bacteria had an average inhibitory zone value for control oil of 17.8mm, Ethylene Glycol 13.6mm, N-Hexane 18.1mm and an average inhibitory zone value for control residue 4mm, Ethylene Glycol 3.38mm , N-Hexane 3mm. Meanwhile, Staphylococcus aureus bacteria had an average inhibitory zone value for control oil of 20.06mm, Ethylene Glycol 22.19mm, N�Hexane 22.19mm and an average inhibitory zone value for control residue 6.25mm, Ethylene Glycol 6.13mm, N- Hexane 5.31mm. Ethylene Glycol Oil is effective against Pseudomonas aeruginosa bacteria, while N-Hexane residue is effective against the same bacteria. Control oil is effective against Staphylococcus aureus bacteria, and for N-Hexane residue it is effective against the same bacteria.
