The Relationship of Tofu Coagulants and Irritant Contact Dermatitis in Tofu Maker at Serang Banten Indonesia

This condition occurs due to direct exposure to irritants, either acutely or persistently. The primary irritants responsible for contact dermatitis are acids or bases. The individuals most susceptible to contact dermatitis are the staff working in the tofu sector. This is because coagulants come into direct touch with personnel during the tofu production process. The study design is an observational analytic approach utilizing the cross-sectional method, which involves a questionnaire. According to this research, the prevalence of ICD among tofu makers in Serang is 59.8%. 85.9% of the workers in this industry are male.
