Abstract: Ammonia (NH3) emissions from livestock sector are one of the large contributors of greenhouse gas. The objective of this research is to determine ammonia emissions at three broiler farmings in Palangka Raya, Central Kalimantan, emissions measurement was conducted at the top and bottom of the poultry house using NH3 sensor conducted in the morning, afternoon and evening. In addition, the measurement is also conducted to the climatic factor, i.e. air temperature, humidity and wind speed. An analysis of the sample of chicken manure is also conducted to determine N and crude protein contained in chicken manure and ration used by poultry farmers during the study. The result of this study reveals that a number of ammonia emissions of the three farming measured on the top of the poultry house is 20,55 ppm, 14,61 ppm and 15,85 ppm, while at the bottom is 18,81 ppm, 15,50 pm and 14,91 ppm. A lot of ammonium emissions of those three farming are influenced by the lack of waste management, crude protein in the ration is not well-digestible so the content of N in the chicken manure is still high and the factor of climatology and humidity surrounding.
