ANALISIS KADAR TIMBAL (Pb) PADA PERMEN BERKEMASAN SECARA SPEKTROFOTOMETRI SERAPAN ATOM (SSA) DENGAN VARIASI LARUTAN PENDESTRUKSI
Siti Nurul Afifah, Diana Candra Dewi, Rahmawati Ningsih
Abstract
Allah berfirman dalam al Qur’an Surat al Ma’idah ayat 88 yang menjelaskan tentang anjuran makanan Halalan Thayyiban. Permen merupakan makanan yang banyak digemari oleh semua kalangan. Dalam permen berkemasan dapat mengandung timbal (Pb) dikarenakan oleh beberapa faktor; diantaranya adalah faktor bahan baku pembuatan permen yang telah mengandung timbal (Pb), faktor media produksi permen yang berbasis logam dengan proses pemanasan, faktor kemasan permen yang mengandung timbal (Pb); serta faktor zat aditif dalam permen.
Penelitian ini meliputi penentuan variasi larutan pendestruksi terbaik antara HNO3 p.a. (30 mL); HNO3 : H2 SO4 (30 mL) perbandingan 3:1 serta HNO3 : H2 SO4 : H2 O2 (30 mL) perbandingan 3:2:1 lalu dilanjutkan dengan uji One Way Annova. Penentuan waktu kestabilan logam terbaik dalam sampel larutan pada hari ke-0; 1; 3; 7 dan hari ke-15. Penentuan kadar timbal (Pb) pada masing-masing sampel hard candy dan uji kesesuaian kadar dengan SNI hard candy.
Hasil penelitian menunjukkan bahwa pada variasi larutan pendestruksi terbaik adalah HNO
3 dan H
2 SO
4 (3:1) dengan nilai rerata konsentrasi yang paling tinggi yaitu 21,35 mg/kg. Hasil Uji Annova adalah F hitung (10215) > F tabel (5,14) yang menunjukkan adanya perbedaan yang siginifikan antara ketiga variasi larutan pendestruksi. Waktu kestabilan diperoleh berdasarkan Uji Annova pada hari ke-3 menuju hari ke-7 dengan hipotesis Ho-nya diterima dengan F hitung (0,455) < F tabel (7,71). Kadar timbal (Pb) yang ditemukan pada kelima sampel permen berkisar antara 25,3 mg/kg hingga 26,8 mg/kg. Berdasarkan acuan Sandar Nasional Indonesia (SNI) No. 3547.1:2008 bahwa kelima sampel permen tersebut tidak layak untuk dikonsumsi karena melebihi nilai ambang batas maksimum cemaran logam timbal (Pb) yaitu 2,0 mg/kg.
