Abstract
INDONESIA:
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 : H2SO4 (30 mL) perbandingan 3:1 serta HNO3 : H2SO4 : H2O2 (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 HNO3 dan H2SO4 (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.
ENGLISH:
Allah says in the Holy Qur'an Surat Al Ma'idah verse 88 which describes the organized food "HalalanThayyiban". Candy is an abundance of food preferred by all circles. In Sachet Candies may contain lead (Pb) due to several factors; between materials of which are factors that have been making candy contains lead (Pb), factor-based media production candy metal heating process, factors candy packaging containing lead (Pb); and additives in candy factor. This research includes the determination of the variation between the best solution of HNO3 p.a. (30 mL); HNO3 : H2SO4 (30 mL) ratio of 3: 1 and HNO3 : H2SO4 : H2O2 (30 mL) ratio of 3: 2: 1 and then proceed to test One Way Annova. The timing of the stability of the best metal in the sample solution on day 0; 1; 3; 7th and 15th day. Determination of lead (Pb) in each sample of hard candy and test compatibility with the rate of SNI hard candy. The results showed that best variations of destruction solution is HNO3 and H2SO4 (3:1) with a mean value of the highest concentration is 21,35 mg/kg. Assay results were calculated F Anova (10215)> F table (5.14) which indicates a significant difference between the three variations of destruction solution. Time stability is obtained based on the Annova Test day 3 day 7 headed by Ho hypothesis is accepted with the calculated F (0.455) <F table (7.71). Levels of lead (Pb) were found in five samples of sweets ranging from 25,3 mg/kg to 26,8 mg/kg. Based on Indonesian national standards reference (SNI) No. 3547.1: 2008 that five samples of candy is not suitable for consumption because it exceeds the maximum threshold value of metal contamination of lead (Pb) is 2.0 mg / kg.
