ANALISA KADAR ETIL ALKOHOL PADA MINUMAN SOJU DENGAN METODE KROMATOGRAFI GAS DAN PENGUKURAN BERAT JENIS DI BALAI
PENGUJIAN DAN IDENTIFIKASI BARANG MEDAN
ABSTRAK
Telah dilakukan analisa kadar etil alkohol pada minuman SOJU yang dilakukan di Balai Pengujian dan Identifikasi Barang (BPIB) Medan.Analisa dilakukan dengan 2 metode yaitu metode pengukuran berat jenis dan metode kromatografi gas. Metode pengukuran berat jenis dilakukan dengan destilasi kemudian hasil destilat diukur berat jenisnya dengan menggunakan piknometer selanjutnya hasil dicocokkan pada tabel. Pada metode instrumen kromatografi gas menggunakan detektor ionisasi nyala. Hasil menunjukkan bahwa analisa kadar etil alkohol pada minuman SOJU dengan metode pengukuran berat jenis sebanyak 17,29% dan metodekromatografi gas sebanyak 18,26%. Kadar etil alkohol pada minuman SOJU telah memenuhi syarat SNI yang ditetapkan.

ANALYSIS OF ETHYL ALCOHOL ON SOJU DRINKS WITH METHOD GAS CHROMATOGRAPHY AND MEASUREMENT OF SPECIFIC GRAVITY AT
TESTING AND IDENTIFICATION OF GOODS IN MEDAN
ABSTRACT
The analysis of ethyl alcohol content in SOJU beverages was conducted at Medan Institute for Testing and Identification of Goods (BPIB). The analysis was done by 2 methods, namely the method of measurement of specific gravity and gas chromatography method. The method of measuring specific gravity is carried out by distillation then the distillate is measured by weight of pyretometer and the results are matched on the table. In the gas chromatographic instrument method using a flame ionization detector. The results showed that the analysis of ethyl alcohol content in SOJU beverage with the method of measuring specific gravity was 17.29% and gas chromatography method was 18.26%. The level of ethyl alcohol in SOJU drink has fulfilled the SNI requirement.
