Abstract

ABSTRAK Air merupakan salah satu sumber daya alam yang memiliki fungsi sangat penting bagi kehidupan manusia dengan meningkatnya kegiatan manusia akan menimbulkan berbagai masalah, salah satunya tercemarnya air pada sumber-sumber air yang mengakibatkan penurunan kualitas air dapat berasal dari limbah terpusat (point sources) dan limbah tersebar (non point sources). Tujuan penelitian ini adalah untuk mengetahui kadar BOD dengan membandingkan metode analisis permanganometri dan iodometri. Objek penelitian ini adalah sampel buatan (artifisial) H_2 C_2 O_4.〖2H〗_2 O dengan variasi konsentrasi 50 ppm; 100 ppm; dan 150 ppm dengan 2 perlakuan masing-masing 4 kali pengulangan. Hasil penelitian ini didapatkan rata-rata persentase perbedaan hasil metode permanganometri berturut-turut yaitu 11,49 ppm; 16,41 ppm; dan 22,18 ppm, sedangkan pada metode iodometri diperoleh hasil berturut-turut 14,73 ppm; 16,93 ppm dan 18,65 ppm. Dari hasil persentasi selisih kadar BOD hasil dan kontrol dapat disimpulkan bahwa persentasi kesalahan metode permanganometri lebih besar dibandingkan metode iodometri.

COMPARISON OF BIOCHEMICAL OXYGEN DEMAND (BOD) LEVELS USING MOMMOMETRY AND IODOMETRY METHODS Teguh Heryanto1, Ana Hidayati Mukaromah2, Diah Hetty Sitomurni3 DIV Health Analyst Study Program Faculty of Nursing and Health, University of Muhamadiah Semarang Clinical Pathology Laboratory Faculty of Nursing and Health, University of Muhamadiah Semarang ABSTRACT Water is one of the natural resources that has a very important function for human life with increasing human activities will cause various problems, one of which is water pollution in water sources which results in a decrease in water quality can be derived from centralized waste (point sources) and scattered waste (non point sources). The purpose of this study was to determine BOD levels by comparing the permanganometric and iodometric analysis methods. The object of this study was artificial samples (artificial) H_2 C_2 O_4.〖2H〗_2 O with variations in the concentration of 50 ppm; 100 ppm; and 150 ppm with 2 treatments each with 4 repetitions. The results of this study obtained an average percentage difference in the results of the successive permanganometric method that is 11,49 ppm; 16,41 ppm; and 22,18 ppm, while the iodometric method obtained 14,73 ppm respectively; 16,93 ppm; and 18,65 ppm. From the results of the difference in BOD levels the results and controls can be concluded that the percentage of errors in the permanganometry method is greater than the iodometry method Keywords:Biochemical Oxygen Demand (BOD), analytical methods, Permanganometry, Iodometry, Wastewater.
