Abstract. Saukoly SA, Meitiniarti VI, Nugroho RA, Krave AS. 2024. Ammonium enrichment reduces the diversity and changes the composition of ammonia-oxidizing microbial communities in agricultural soil media. Biodiversitas 25: 916-923. Nitrification is the process of ammonium oxidation to form nitrites and nitrates. Ammonium availability in the soil is one of the factors influencing the activity, abundance, and diversity of ammonia-oxidizing microorganisms (AOM). This study aimed to determine the effect of enriching a soil media with different ammonium concentrations on the abundance and diversity of AOM as well as the potential for nitrification. Soil as the media was prepared from an agricultural land receiving cow dung sewage. The media was then placed in the microcosms, and was added to a nitrification medium containing ammonium at three levels; 0 (control soil), 200 (low ammonium-enriched soil), and 500 mg L-1 (high ammonium-enriched soil). The microcosms were further incubated for 42 days at room temperature. The nitrification potential determination was based on the formation of nitrite from ammonium oxidation. The abundance of AOM and the potential nitrification were measured every 14-day interval, including day 0 as the initial condition. The AOM composition was analyzed based on the similarity level of the amoA gene sequence to the NCBI BLAST GenBank database. However, this analysis was only conducted for the control and high ammonium-enriched soil. This study indicated that ammonium enrichment increased the nitrification activity and the abundance of AOM, but it decreased the diversity of AOM communities. There were positive correlations between nitrification and nitrate potential, as well as between ammonium content and AOM abundance. Negative correlations appeared between pH and nitrification potential, nitrate concentrations, ammonium concentrations, and MPN. The diversity of ammonium-oxidizing archaea (AOA) in the control soil was higher than in the high ammonium-enriched soil. The enrichment with ammonium also changed the AOA composition. The Candidatus Nitrosocosmicus oleophilus strain of the MY3 chromosome was the most dominant archaea in the control and high ammonium-enriched soil. This implies that the high diversity of AOA in this soil may be beneficial for further use of the soil as a source for inocula in the development of nitrifiers-based biofertilizers.

“…Pupuk NPK dan urea yang mengandung nitrogen tersebut akan mengalami proses nitrifikasi dalam tanah dan menghasilkan senyawa nitrat dan nitrit. Proses perubahan pupuk khususnya pupuk urea menjadi nitrit dan nitrat terjadi pada minggu ke-4 setelah pemupukan (25) . Selanjutnya, kedua senyawa tersebut masuk ke dalam permukaan tanah karena terbawa oleh air hujan atau air irigasi.…”

Latar belakang: Penggunaan pupuk nitrogen seperti NPK dan urea pada lahan pertanian dapat menyebabkan pencemaran pada air tanah di wilayah pertanian. Pupuk nitrogen yang diaplikasikan pada tanah akan mengalami leaching terbawa air hujan masuk ke dalam tanah. Konsumsi air tanah yang mengandung nitrat dan nitrit dapat mengakibatkan dampak kesehatan seperti Blue Baby Syndrome atau Methemoglobinemia dan kanker. Penelitian ini dilakukan untuk menganalisis konsentrasi nitrat dan nitrit pada air tanah dan mengukur tingkat risiko kesehatan yang ditimbulkan dari kedua pajanan ini terhadap penduduk di Desa Cihambulu, Subang.Metode: Penelitian ini dilakukan pada bulan Februari 2021 dengan menggunakan metode Analisis Risiko Kesehatan Lingkungan. Wawancara dilakukan kepada 123 responden dari 33 unit rumah tangga untuk memperoleh informasi berat badan, laju konsumsi dan lama tinggal responden di lokasi penelitian.. Sebanyak 33 sampel air tanah diambil dari 33 unit rumah tangga yang telah dilakukan wawancara. Pengukuran tingkat risiko kesehatan dilakukan dengan menghitung nilai Risk Quotion (RQ) dari masing-masing kelompok responden anak, wanita dan pria dewasa. Hasil: Hasil analisis menunjukkan konsentrasi nitrat (NO3-N) pada air tanah berkisar antara 0,03 - 6,7 mg/L dengan rata-rata 1,38 mg/L sedangkan konsentrasi nitrit (NO2-N) pada air tanah berkisar antara 0,01 - 0,08 mg/L dengan rata-rata 0,02 mg/L. Tingkat risiko kesehatan non karsinogenik menunjukkan nilai RQ < 1 untuk 3 (tiga) kelompok responden yaitu anak, wanita dan pria dewasa.Simpulan: Seluruh sampel air tanah masih memenuhi baku mutu dalam Peraturan Menteri Kesehatan Nomor 492/Menkes/Per/IV/2010 tentang Persyaratan Kualitas Air Minum, untuk parameter nitrat dan nitrit. Tingkat risiko kesehatan non karsinogenik yang disebabkan dari kedua pajanan tersebut pada air tanah menunjukkan nilai RQ < 1 dimana kedua pajanan tersebut belum beresiko menimbukan efek merugikan bagi kesehatan. ABSTRACT Title: Health Risk Assessment of Nitrate and Nitrite in Groundwater in the Agricultural Area, Cihambulu Village, Subang,Background: The use of nitrogen fertilizers such as NPK and urea on agricultural land can cause contamination of groundwater in agricultural areas. Nitrogen fertilizer applied to the soil will be carried by rainwater into the soil. Consumption of groundwater containing nitrates and nitrites can lead to health effects such as Blue Baby Syndrome or Methemoglobinemia and cancer. This study was conducted to determine the concentration of nitrate and nitrite in groundwater and to determine the level of health risk posed by these two exposures to residents in Cihambulu Village, Subang..Method: This study was conducted in February 2021 using the method of Environmental Health Risk Assessment. Interview were conducted with 123 respondents from 33 household units to obtain information on weight, consumption rate and length of stay of respondents in the study location. A total of 33 groundwater samples were taken from 33 household units that had been interviewed.Result: The results shows that the concentration of nitrate (NO3-N) in groundwater ranged from 0.03 - 6.7 mg/L with an average of 1.38 mg/L while the concentration of nitrite (NO2-N) in groundwater ranged from 0.01 - 0.08 mg/L with an average of 0.02 mg/L. The level of non-carcinogenic health risk shows an RQ value < 1 for 3 (three) groups of respondents, namely children, women and adult men.Conclusion: All groundwater samples contain nitrate and nitrite within acceptable limits according to the requirements in the Regulation of the Minister of Health Number 492/Menkes/Per/IV/2010 concerning Requirements for Drinking Water Quality, especially nitrate and nitrite requirementrs. The level of non-carcinogenic health risk caused by this exposures to groundwater shows an RQ value < 1 where the two exposures are not at risk of causing adverse health effects.

Nitrogen fertilization is needed as a source of nitrogen in the growing plants. Nitrogen in the environment will undergo a transformation in the form of compounds such as nitrate (NO3 −) and nitrite (NO2 −). The transformation from nitrogen to nitrate, nitrite, will have a negative impact on the aquatic environment namely the formation of toxic conditions. The main purpose of this research was to study the residual nitrogen fertilizer in the outlet of paddy irrigation upper Tondano Watershed and to evaluate the residual nitrogen fertilizer in the outlet of paddy irrigation upper Tondano Watershed 5-years period (2015-2019). Water quality sampling was carried out using a composite sampling method at two sample locations in River Panasen, in situ measurement of water temperature parameters, and pH. Analysis of the parameters of nitrate and nitrite was carried out in the laboratory. Data were analyzed using descriptive statistics. The results showed that the concentration nitrate of -0.9330-153 mg/l (according Government standard PP No. 82/2001 nitrate 10 mg/l), and nitrite of 0.001 mg/l-0.52 mg/l exceed PP No. 82/2001 quality standard (0.006 mg/l).
