Abstract

Analytical chemistry is one branch of chemistry in which there is a way to determine certain ion levels using selective and specific reagents. One type of ion that can be known is the sulfate ion. Sulfate ions are one of the main anions that appear in water naturally. Sulfate is one of the important ions in water availability because of its important effect on humans when it is available in large quantities. The maximum limit of sulfate in water is around 250 mg / L for human-consumed water. This study uses qualitative analysis to determine whether water in the Jakabaring Sport City Palembang region contains sulfate ions or not. Samples taken directly from five different points were reacted with HCl and BaCl2. The results obtained are the five positive water samples containing sulfate ions which are characterized by the formation of white deposits.

Abstract

ABSTRAK Masalah kehalalan produk pangan di Indonesia mendapat perhatian khusus adanya cemaran daging bersifat non-halal. Salah satunya daging tikus pada produk halal makanan bakso KM 9 Palembang. Percobaan ini diharapkan dapat menjadi salah satu dasar tercapainya penjaminan produk halal terhadap produk bakso sapi, agar tidak tecemar daging tikus non-halal. Penggunaan spektrofotometri FTIR digunakan untuk mengidentifikasi adanya daging tikus pada bakso sapi secara kualitatif. Sampel bakso sapi diekstrak dengan kloroform menggunakan corong pisah pada suhu ruang. Hasil analisa menunjukkan bahwa tidak terdapat cemaran tikus pada bakso daging sapi yang dibuktikan oleh spektra FTIR dan uji kualitatif yang telah dilakukan. Kata Kunci: Bakso Sapi; Fourier Transform Infrared; Lemak Tikus; Produk Halal
