Abstract
INDONESIA :
Makanan gorengan merupakan salah satu jenis jajanan favorit yang banyak dikonsumsi masyarakat Indonesia. Makanan gorengan dapat tercemar oleh logam timbal disebabkan oleh beberapa faktor, salah satunya dari pembungkus gorengan seperti kertas bekas atau kantong kresek . Tujuan dari penelitian ini adalah untuk mengetahui kadar timbal akibat penggunaan pembungkus gorengan dengan variasi waktu kontak.
Jenis penelitian yang dilakukan adalah experimental laboratory, yang meliputi: preparasi sampel, pengaturan alat Spektroskopi Serapan Atom (SSA), pembuatan kurva standar, analisis kadar logam timbal (Pb) dalam tiap sampel gorengan berdasarkan variasi pembungkus (tanpa pembungkus, kertas koran, kertas minyak, kresek putih, kresek hitam) dan waktu kontak (60, 120, dan 180 menit) dengan metode destruksi basah tertutup (refluks), menggunakan zat pengoksidasi yaitu HNO3 p.a + H2SO4 p.a (3:1) sebanyak 15 mL dan 1 gr sampel. Penentuan kadar timbal (Pb) menggunakan Spektroskopi Serapan Atom (SSA) pada panjang gelombang 217 nm.
Hasil dari analisis kadar logam timbal (Pb) pada gorengan berdasarkan variasi jenis pembungkus dan waktu kontak (60; 120; 180 menit) yang melebihi ambang batas SNI adalah sampel gorengan dengan pembungkus kertas minyak pada waktu kontak 180 menit sebesar 2,07 ppm, dan sampel gorengan dengan pembungkus kresek hitam pada waktu kontak 120 dan 180 menit yaitu sebesar 2,15 dan 4,12 ppm. Sedangkan hasil dari two way ANOVA menunjukan F hitung (517,166) > F tabel (2,04) yaitu data diterima yang berarti penggunaan jenis pembungkus dan waktu kontak berpengaruh terhadap kadar timbal dalam gorengan. Semakin lama waktu kontak pembungkus dengan makanan maka semakin tinggi pula logam timbal (Pb) yang bermigrasi dari pembungkus terhadap makanan.
ENGLISH :
Fried food is one of the favorite snacks which is widely consumed by the society of Indonesia. Fried food can be polluted by lead metal which is influenced by some factors. One if its is fried food wrap such as paper or plastic. The purpose of this research is to acknowledge the level of lead due to the use of fried food wrapping with the variation of contact time.
The kinds of research done is experimental laboratory which includes: sampling preparation, Atomic Absorption Spectroscopy (SSA) tool, the use o standard curve, the analysis of lead level (Pb) in every sample of fried food based on wrapping variation (without wrap, newspaper wrap, oil paper, white plastic, black plastic) and contact time (60 minutes, 120 minutes, 180 minutes) and with the destruction method of being wet closed (reflux), using the substance of oxidizer which is HNO3 p.a + H2SO4 p.a (3:1) as many as 15 mL and 1 gr sample. The decision of lead level (Pb) using Atomic Absorption Spectroscopy (SSA) in the wave as long as 217 nm.
The results of the analysis of lead metal content (Pb) on fried foods based on variations in the type of wrapping and contact time (60; 120; 180 minutes) that exceeded the SNI threshold were fried samples with oil paper wrap at 180 minutes contact time of 2.07 ppm, and fried samples with black crackle wrap at 120 and 180 minutes of contact time were 2.15 and 4.12 ppm. While the results of two way ANOVA show F count (517,166)> F table (2.04) that is the data received which means that the use of the type of wrapper and contact time affect the lead level in fried foods. The longer the contact time of the wrapper with food, the higher the lead metal (Pb) that migrates from the wrapper to food.
