Environmental Health Risk Analysis of NH₃ Exposure Around a Laying Chicken Farm in Darsono, Jember [Accepted]

Abstract

Laying hens farming is one of the agricultural sub-sector that plays a role in fulfilling animal food. Livestock is a producer of ammonia emission in the atmosphere. Ammonia has a negative impact on public health and the environment. This study aims to analyze the environmental health risks of exposure to ammonia gas around laying hens farms. The research was carried out using a descriptive design method of environmental health risk analysis (EHRA). The population in this study was the community around the laying hen farm with a sample of 95 respondents. Measurement of ammonia gas was carried out using a spectrophotometer using the Indophenol method based on SNI 19-7119.6-2005. Air samples were taken at three points. The results of this study showed that the largest concentration was 0,00807 mg/Nm³ and the lowest was 0,00711 mg/Nm³. Based on an analysis of environmental health risks, the RQ value at the highest concentration was 0,00466 for the adult population and 0,00618 for the child population. The conclusion of this study is that exposure to ammonia gas in the adult population weighing 55kg and the child population weighing 25kg around the laying hen farm in Darsono Village is still within safe limits for a frequency of 350 days/year for the next 9 years. The advice that can be given is that the farm concerned needs to carry out livestock waste management as a source of ammonia emissions in laying hen farms.
