PENENTUAN KADAR AMMONIA (NH3) PADA AIR BAKU DAN AIR RESERVOIR WTP MINI KELAMBIR V DI PDAM TIRTANADI
SECARA SPEKTROFOTOMETRI
ABSTRAK
Penentuan kadar Ammonia (NH3) pada air baku dan air reservoir WTP Mini
Kelambir Lima di PDAM Tirtanadi telah dilakukan secara spektrofotometri. Penentuan ini dimaksudkan untuk mengetahui kadar ammonia pada air baku dan air reservoir yang sesuai dengan standar kualitas air. Penentuan kadar ammonia pada air baku dan air reservoir WTP Mini Kelambir Lima dilakukan dengan terlebih dahulu ditambahkan Mineral Stabilizer, Polivynil Alkohol Dispersing Agent dan reagen Nessler. Kadar ammonia diukur pada λ 425 nm dengan menggunakan spektrofotometer DR 2010. Hasil pemeriksaan kadar ammonia pada air baku dan air reservoir adalah 0,573 mg/L pada air baku dan 0,020 pada air reservoir. Kadar ammonia pada air baku telah melebihi ambang batas standart kualitas air berdasarkan Peraturan Pemerintah Republik Indonesia No.82 Tgl 14 Desember 2001 tentang Air Baku Mutu Kelas I yaitu 0,5 mg/L, sehingga air baku WTP Mini Kelambir V harus dilakukan pengolahan lebih lanjut agar dapat dikonsumsi. Sedangkan kadar ammonia pada pada air reservoir masih memenuhi standart Permenkes No. 492/Menkes/Per/IV/2010 Tanggal 19 April 2010 tentang syarat kualitas air minum yaitu 1,5 mg/L sehingga dapat dikonsumsi sebagai air minum.

DETERMINATION OF AMMONIA (NH3
ABSTRACT
) RATE IN RAW WATER AND RESERVOIR WATER OF WTP MINI KELAMBIR V AT PDAM
TIRTANADI BY SPECTROPHOTOMETRY
Determination of Ammonia (NH3
Key Words: Ammonia, Spectrophotometry, Raw water, Reservoir water
) rate in raw water and reservoir water WTP Mini Kelambir V at PDAM Tirtanadi by spectrophotometry has been. Determination is intended to determine levels of ammonia in the raw water and reservoir water are in accordance with the water quality standards. Determination of ammonia in the raw water and reservoir water WTP Mini Kelambir V performed by first added Mineral Stabilizer, Polivynil Alcohol Dispersing Agent and Nessler reagent. Measuring ammonia rate of λ 425 nm with Spektrophotometer DR 2010 . The examination of ammonia in the raw water and the reservoir water is 0.573 mg / L in raw water and 0,020 on the reservoir water. Levels of ammonia in the raw water has exceeded the threshold of water quality standards based on the Indonesian Government Regulation 82 date of December 14, 2001 on Air Quality Standards Class I is 0.5 mg / L, so that the raw water WTP Mini Kelambir V should do further processing that can be consumed. While the levels of ammonia in the water reservoir still meet the standard Permenkes No. 492 / Menkes / Per / IV / 2010 April 19, 2010 on the condition of the quality of drinking water is 1.5 mg / L it can be consumed as drinking water.
