Cans are widely used as primary packaging in various food products. Ferrous (Fe) and zinc (Zn) metal as the constituent components in the manufacture of can packaging bodies can experience corrosion and dissolve in food so that it will affect food quality and finally affect to health. This study aimed to determine the content of Fe and Zn metal at different treatments (time) with 3% acetic acid and vegetable oil as food simulators on can packaging using Atomic Absorption Spectrophotometer (AAS). The results of the analysis showed that the range of Fe and Zn metal content in 3% acetic acid food simulants were respectively 0.15-27.46 mg/kg and 0.00060.007 mg/kg, while in vegetable oil simulants 3% Fe and metal content Zn were 0.6-2.46 mg/kg and 0.00040.0025 mg/kg with 80-100% recovery, respectively. Thus, food from can packaging should not be exposed to oxygen for a long time, especially when it has been opened because it will increase the leaching of Fe and Zn metals from the packaging into food.

STUDI PENURUNAN KADAR LOGAM BESI (Fe) DAN LOGAM TEMBAGA (Cu) PADA AIR EMBUNG MENGGUNAKAN ADSORBEN NANOSILIKAABSTRAKPolusi limbah logam berat dalam air merupakan satu permasalahan lingkungan yang penting. Dalam mengatasi permasalahan tersebut dapat dilakukan purifikasi terhadap air tersebut. Metode yang dapat digunakan untuk purifikasi limbah sangat beragam salah satunya adalah absorpsi. Secara umum metode absorpsi telah banyak digunakan dalam purifikasi air limbah. Metode absorpsi dapat menurunkan kadar logam yang terlarut pada limbah. cair dengan cara menyerap logam-logam tersebut ke dalam permukaan absorbennya. Tujuan dilakukan penelitian ini adalah  untuk menurunkan konsentrasi logam besi (Fe) dan tembaga (Cu) menggunakan adsorben nanosilika. Penelitian ini menggunakan variabel bebas yaitu waktu pengadukan (20 menit, 40 menit, dan 60 menit). Hasil akhir filtrat air embung kemudian diukur absorbansinya menggunakan Spektrofotometer Serapan Atom. Berdasarkan hasil analisa menggunakan instrumen SSA diperoleh hasil bahwa tidak terjadi penurunan logam Fe maupun Cu. Dalam hal ini terjadi peningkatan konsentrasi dalam logam Fe maupun Cu, hal ini dikarenakan kurangnya waktu pengadukan dan pengaruh dari adsorben nanosilika.Kata Kunci: limbah, logam berat, nanosilika STUDY OF DECREASING METALS IRON (Fe) AND COPPER (Cu) ON EMBUNG WATER USE OF NANOSILICA ADSORBEN ABSTRACTHeavy waste pollution of heavy metals in the water is an important environment issue. To solve the problem, its can be purified the water. The methods that can be used for waste purification are very diverse, one of which is absorption. In general, the method of absorption has been widely used in wastewater purification. The absorption method can decrease dissolved metal content in the waste. liquid by absorbing the metals into the absorbent surface. Research has been conducted to reduce the concentration of iron (Fe) and copper (Cu) by using nanosilica adsorbent. This research used to independent variable that is stirring time (20 minutes, 40 minutes, and 60 minutes). The final result of filtrate embung water then measured its absorbance using Atomic Absorption Spectrophotometer (AAS). Based on the result of the analysis using SSA instrument, it is found that there is no decrease of Fe and Cu metals. There are several reasons for those problem such as due to lack of stirring time and the influence of nanosilica adsorbent.Keywords: Waste pollution, heavy metal, nanosilica

Contamination of Copper in Mugil dussumeri (Actinopterygii: Mugilidae, Forsskål, 1775) which was caught in Semarang waters, Indonesia The marine environment in Semarang waters are highly polluted by heavy metals such as copper (Cu).  On the other side, these areas have become producers of fishery commodities such as mullet fish Mugil dussumieri. The aims of this study was to determine the heavy metal content of Cu in mullet fish during wet monsoon (December 2017 and February 2018). Atomic Absorption Spectrophotometer were used to analysis of Cu concentration in marine water and fish meat.  The results show that the Cu content in marine water was not detected while in the meat of mullet fish during December 2017 and February 2018 were 0.66 ± 0.07 mg/kg and 0,604 ± 0.217 mg/kg, respectively. The results were still within the quality standard for maximum limit of Cu content allowed in seafood by FAO/WHO. Lingkungan perairan laut di sekitar Semarang berpeluang sangat tinggi untuk terpolusi logam berat tembaga.  Di lain sisi perairan ini menjadi daerah produksi perikanan seperti ikan belanak Mugil dussumieri. Tujuan dari penelitian ini adalah untuk mengetahui kandungan logam Cu dalam daging ikan belanak yang ditangkap selama musim penghujan (Desember 2017 dan Februari 2018). Untuk mengetahui konsentrasi Cu dalam air laut dan ikan belanak digunakan Atomic Absorption Spectrophotometer.  Hasil penelitian menunjukkan bahwa konsentrasi logam Cu selama bulan Desember 2017 adalah 0.66 ± 0.07/kg dan selama bulan Februari 0,604 ± 0.217 mg/kg, sedangkan konsentrasi Cu dalam air laut tidak terdeteksi.  Hasil penelitian dapat disimpulkan bahwa kandungan Cu dalam ikan belanak masih berada pada konsentrasi yang diperbolehkan oleh FAO/WHO.

Sweetened condensed milk is generally packaged in a can which is made from iron and zinc. Iron and zinc can have corrosion with the increasing of contact time and changing condition so that they will contaminate the milk. The purpose of this research are to determine the best wet destruction method, find out the effect of adding 30% H2O2 at varied volume in the process of wet destruction, to find out Fe and Zn content in expire and non-expired sweetened condensed milk and to compare the results with the national quality standard. Sample was wet destructed by using variation of 70% HNO3: 30% H2O2 which is 3:0 (method A); 3:0.5 (method B) 3:1 (method C); 3:2 (method D) then the results were measured by using Atomic Absorption Spectrophotometer. Analysis of Fe used standard addition curve method whereas the analysis of Zn used calibration curve method. The results of the analysis showed that the best variation of HNO3:H2O2 in wet destruction method was 3:0.5 for Fe analysis and 3:2 for Zn analysis. The addition of 30% H2O2 at varied volume in wet destruction for Fe analysis gave significantly different results for non-expired sweetened condensed milk but were not significantly different for expired sweetened condensed milk. Whereas, the analysis of Zn gave significantly different results for both non-expired and expired sweetened condensed milk. The metal content in the expired and non-expired sweetened condensed milk which were wet destructed by using the best solvent compotition obtained  0,2759 and 0,7126 mg/kg for Fe and 4,1645 and 2,4367 mg/kg for Zn metal. The Fe and Zn content in the sweetened condensed milk are still below the maximum limit that set by SNI. Keywords: Fe, H2O2, Atomic Absorption Spectrophotometer, sweetened condensed milk, Zn
