Noise is a physical factor in the work environment that may cause health problems when it exceeds the permissible threshold. PT. PLN (Persero) ULPLTD Labuhan, a diesel power plant unit, generates continuous noise from diesel engines and supporting equipment. This study aimed to determine the noise level at each measurement point and to analyze the spatial distribution of noise using the Surfer application. A quantitative descriptive method was applied, with measurements taken at seven points using a Sound Level Meter for 10 minutes at each point. Data were processed into Equivalent Continuous Noise Level (Leq) values and mapped in Surfer using the Inverse Distance Weighting (IDW) interpolation method. Results showed noise levels ranging from 58.1 to 69.3 dBA, with the highest value in the warehouse area and the lowest in the northern residential area. The noise map indicated that operational areas experienced higher noise exposure than residential areas, forming a decreasing gradient toward the surrounding residential zone. Noise levels in the work area remained below the 85 dBA occupational threshold, whereas the surrounding residential areas exceeded the 55 dBA environmental quality standard, indicating that distance and building layout influence the spatial pattern of noise exposure around the plant.
