The impact of noise due to the construction of a Steam Power Plant can have a negative impact on the surrounding environment. This study aims to assess the initial baseline condition of environmental noise before the existence of development activities, predictions after activities, and actions to manage/monitor the impact of noise that occurs. The research method is evaluative descriptive using the integrating sound level meter. The research data are the equivalent noise level (Leq), daytime noise level (LS), night noise level (LM), and day-night noise level (L-SM) from 9 sampling locations. The results of the noise analysis are categorized based on scale and compared with the Decree of the Minister of Environment of the Republic of Indonesia No. Kep-48 / MENLH / 11/1996 and IFC - EHS guidelines. Noise level data The initial environmental baseline of the laydown area utilization stage at scale 2, land clearing stage at scale 1, the construction phase of the main building, and supporting facilities at scale 1. The value of the scale of the noise level is assessed based on the difference in impact components that is smaller than the difference in the average environmental scale, so that the impact category is a manageable impact. The direction for controlling the impact of noise is to install a project guardrail, activities are carried out at 07.00 - 19.00 WIB and and tree planting. Environmental management and monitoring have been carried out well, the evaluation trend shows a decline.
Noise distribution modeling during land clearing
Noise distribution during the construction of the main building and its supporting facilities
The environmental baseline before and after the activity shows an average scale of 2. If the scale value based on the difference of each impact component is smaller than the difference between the average environmental scale, then the impact can be managed. The impact of the noise level due to the construction of a steam power plant is in the manageable category. The direction for noise control in construction activities is to install a project boundary fence at the Lay Down Area location associated with residential areas, activities are carried out at 07.00-19.00 WIB. If activities are required above 19.00 WIB, the Initiator will coordinate with the surrounding community.
