Abstract :
Tujuan Penelitian: Mengetahui besarnya kontaminasi logam yang terlepas pada alat masak
dapur serta potensi bahaya kesehatan bagi tubuh manusia
Metode Penelitian: Penelitian di laboratorium menggunakan motode XRF untuk mengetahui
komposisi logam penyusun pada alat masak alumunium, stainless steel, stainless steel berlapis
titanium dan teflon. Selanjutnya hasil dari XRF digunakan sebagai acuan penentuan logam yang
berpotensi terlepas menjadi kontaminan yang akan diperiksa menggunakan ICP-OES.
Pemeriksaan kadar logam yang terlepas diperiksa menggunakan ICP-OES dengan empat
sampel 250 ml air aqua gallon ditambahkan 3 gr bikarbonat bubuk lalu dipanaskan keempat
sample pada masing-masing material alat masak hingga mendidih.
Hasil Penelitian: Alat masak dapur yang paling sedikit melepaskan kontaminannya adalah
Stainless Steel. Selanjutnya, konsentrasi logam penyusun alat masak tidak selalu berbanding
lurus dengan besarnya kontaminan logam yang dilepaskan.
Saran: Diharapkan dengan adanya penelitian ini masyarakat dapat memilih material alat masak
yang lebih sedikit melepaskan kontaminan logam.
Kata Kunci : ICP-OES, Kontaminan, XRF. / Research puposes: Knowing the amount of metal contamination that released from the kitchen
cooking utensils and its potential risk to the human body
Methods: The research was conducted in the laboratory using the XRF method to determine
the composition of the constituent metal in the aluminum cookware, titanium-coated stainless
steel, and teflon. Then the results of the XRF used as a reference in determining potentially
detached metals that able to become the contaminants to be examined using ICP-OES. The
examination of the released metal content using ICP-OES with 4 samples of 250 ml gallon
water added by 3 grams of powdered bicarbonate, then the four samples were heated in each
cookware until the samples reach boiling point.
Results: Out of the 4 samples that being studied, the kitchen cookware that released the
contaminants was stainless steel. Furthermore, the concentration of constituent cookware is not
always directly proportional to the amount of metal contaminants that being released.
Suggestion: It is expected that with this research the public can choose the kitchen cooking
utensils that release less metal contaminants.
