Introduction: The implementation of Occupational Safety and Health (OSH) standards is often neglected in the informal sector, particularly in tofu factories, leading to increased health risks for workers. This study aims to analyze the relationship between workload, work duration, and water consumption on the incidence of heat strain among workers at the Purwogondo tofu industry center in Kartasura. Method: This study employed a cross-sectional design involving 80 participants selected using purposive sampling. Data on workload (measured via pulse rate), work duration, and water intake (both assessed through questionnaires) were collected alongside heat strain levels, which were evaluated using the Heat Strain Score Index (HSSI). Chi-square tests were subsequently utilized to analyze the relationships between the independent and dependent variables. Results: Chi-square tests revealed significant associations (p<0.05) between all three variables and heat strain, with Cramer's V indicating work duration as the strongest predictor (0.626), followed by water consumption (0.480) and workload (0.359). Results showed 60% of workers were at risk (Yellow Zone) and 27.5% experienced heat strain (Red Zone), particularly those with moderate workloads (52.2%), extended shifts (31.9%), and inadequate hydration (41.2%). Conclusion: The results emphasize the critical necessity for managing workloads, regulating shifts, and implementing hydration programs in small-scale food industries that are exposed to heat.
