ABSTRAK
Telah dilakukan analisa kadar COD dan Amoniak dari beberapa limbah cair pabrik kering sehingga dapat diketahui nilai Amoniak dan COD apakah telah memenuhi standart baku mutu limbah cair yang ditetapkan.didalam analisa ini metode yang digunakan metode Spektrofotometer dan titrasi. Dari hasil analisis yang dilakukan diperoleh kadar Amoniak pada contoh 1 = 43,45 contoh 2 = 0,365 contoh 3 = 50,65 contoh 4 =13,27 contoh 5 = 44,65 contoh 6 = 4,47 contoh 7 = 74,625 contoh 8 = 40,887. Kadar COD pada contoh 1 = 403,26 contoh 2 = 60,8 contoh 3 = 481,844 contoh 4 = 113,74 contoh 5 = 332,948 contoh 6 = 105,468 contoh 7 = 904,772 contoh 8 =55,852.Dari bebeapa hasil analisa ada sebagian contoh yang memenuhi standart baku mutu dan ada sampel yang tidak memenuhi standart baku mutu yang ditetapkan oleh Menteri Lingkungan Hidup, maka air limbah tersebut tidak dapat dibuang ke badan air.

ABSTRACT
Have performed the analysis of COD and Ammonia levels of some dry mill effluent that can be known whether the value of ammonia and COD has met the standard of wastewater quality standards ditetapkan.didalam this analysis method used Spectrophotometer and titration methods. From the results of the analysis carried Ammonia levels obtained in Example 1 = 43.45 Example 2 = 0.365 Example 3 = 50.65 = Example 4 = 13,27 Example 5 = 44,65 Example 6 = 4,47 Example 7 = 74.625 Example 8 = 40.887. COD concentration in example 1 = 403.26 Example 2= 60,8 Example 3 = 481,844 Example 4 = 113.74 Example 5 =332,948 example 6 = 105,468 example 7 = 904,772 example 8=55,852.Dari some analysis results there are some examples meet the standard quality standards and there are samples that do not meet the standard of quality standards established by the Minister of the Environment, the waste water can not be discharged into water bodies.
