Evaluation of noise intensity is carried out by making a noise map that describes the noise distribution pattern from 278 measurement points and then processed with surfer software, which then becomes basic information to protect workers from the risk of hearing loss. After measuring and analyzing the data, the noise level ranged from the lowest of 41.0 dBA, to the highest of 101.9 dBA. From the noise map, it can be seen that the main sources of noise are in the workshop area, corn intake & dryer area, generator area & bagging off area. Noise control efforts have been carried out by engineering controls, administrative controls in the form of work rotation, Standard Operating Procedures, training, safety signs and the use of ear protective equipment for workers in the form of earplugs and earmuffs.

INTRODUCTION Industrial noise has long been a problem that until now has not been able to be handled properly, so that if it does not get more attention it can become a serious threat to the hearing health of workers. Therefore, the company must be able to overcome it by carrying out control measures, being able to identify the sources of noise correctly and taking corrective and preventive actions so that workers can be avoided from disturbances due to noise and can improve their optimal health status. 2. LITERATURE REVIEW 2.1. Definisi According to permenaker no. 5 of 2018 (regulation of the minister of manpower and transmigration of the republic of indonesia no. 5 of 2018 concerning environmental occupational safety and health, 2018) noise is all unwanted sounds originating from production process tools and or work tools that are at a certain level can cause hearing loss. 2.2. Noise Source Noise caused by the process of production machines (compressor machines, water pump machines, venting, steam drums, etc.) as well as the use of work equipment in the work process is caused by collisions and friction of work equipment, which are generally made of hard objects or metal. . Noise inside the building comes from plumbing, boilers, generators, air conditioners and fans. Noise outside the building comes from emergency vehicles, traffic and refuse collection. 2.3. Noise Type a. Continuous noise with a wide frequency spectrum (steady state, wide band noise), for example noise from machines, fans, and others.
