Abstrak

Solid medical waste management in hospitals continues to face a gap between operational standards and on-site practices, thereby posing potential health and environmental risks. This study aimed to develop a SEM-PLS model of solid medical waste management based on healthcare workers’ knowledge, attitudes, and practices at Subang District General Hospital. An analytic correlational quantitative study with a cross-sectional design was conducted among 251 healthcare workers selected using proportional sampling with purposive eligibility criteria. Data were collected using a Knowledge–Attitude–Practice (KAP) questionnaire and analyzed with SmartPLS to assess construct validity, reliability, and direct and indirect inter-construct relationships. The results showed that knowledge had a significant effect on attitude (T = 22.48, p < 0.001), but did not directly affect practice/behavior (T = 0.20, p = 0.838). Attitude significantly influenced practice (T = 10.75, p < 0.001) and served as a mediating variable between knowledge and practice (T = 9.51, p < 0.001). These findings indicate that knowledge becomes practically meaningful when it is internalized as a positive attitude toward safety and compliance. Strengthening attitudes and fostering a workplace safety culture are therefore essential to improving compliance with solid medical waste management. Recommended interventions include applied, practice-oriented training, enhanced supervision, and strong managerial support to promote safe and sustainable practices.
