Abstract

Semakin tingginya pemakaian aluminium foil sebagai kemasan makanan dan minuman sekali pakai, menyebabkan jumlah sampah semakin meningkat. Sehingga pengelolaan sampah melalui open dumping landfill dan pembakaran kurang sesuai. Untuk mengurangi jumlah sampah, pemerintah berupaya membentuk sistem ekonomi sirkular dengan implementasi 4R. Oleh karena itu dengan melakukan recovery kemasan alauminium foil menjadi tawas padat, diharapkan mampu mengurangi jumlah sampah kemasan dan mengurangi penggunaan bauksit sebagai bahan baku tawas. Selain itu berdasarkan Permenperin No. 67/M-IND/PER/12/2013 menyatakan bahwa tawas padat maupun cair masuk dalam kategori Wajib SNI, sesuai syarat mutu SNI 0032:2011. Sehingga penelitian ini bertujuan untuk merecovery aluminium foil menjadi tawas padat agar sesuai syarat mutu SNI 0032:2015. Dari hasil penelitian diperoleh tawas yang dihasilkan adalah jenis tawas kalium atau potash alum dengan titik maksimum yang diperoleh yaitu pada kondisi penggunaan larutan KOH 3 M dan H2SO4 3 M dengan nilai yield 99,59% dengan kadar Al2O3 11,19%, dan dengan suhu pengeringan kristal 150oC selama 2 jam mampu menaikkan kadar Al2O3 menjadi 17,32%, sehingga tawas yang dihasilkan sesuai syarat mutu SNI 0032:2011. Kinetika reaksi untuk proses recovery aluminium dari aluminium foil dalam larutan KOH pada suhu ruang 25 oC diperoleh -rA = 0,006.CA. Hasil uji performa untuk koagulasi pada limbah domestik menunjukkan bahwa tawas kalium hasil sintetis lebih baik daripada tawas komersil berdasarkan penurunan parameter kekeruhan, Total Suspended Solid (TSS) dan Total Dissolved Solid (TDS).

The increasing use of aluminum foil as disposable food and beverage packaging causes the amount of waste to increase. So, waste management through open dumping in landfills and burning is not appropriate. To reduce the amount of waste, the government is trying to form a circular economy system with the implementation of 4R. Therefore, by recovering aluminum foil packaging into solid alum, it is expected to be able to reduce the amount of packaging waste and reduce the use of bauxite as a raw material for alum. In addition, Permenperin No. 67/M-IND/PER/12/2013 states that both solid and liquid alum are included in the Compulsory SNI category, according to the quality requirements of SNI 0032:2011. So, this study aims to recover aluminum foil into solid alum so that it meets the quality requirements of SNI 0032: 2015. From the research results, it was found that the alum produced was a type of potassium alum or potash alum with the maximum point obtained, namely in the conditions of using 3 M KOH and 3 M H2SO4 solutions with a yield value of 99,59% with 11,19% Al2O3 content, and with a drying temperature 150oC crystals for 2 hours were able to increase the Al2O3 content to 17.32%, so that the alum produced met the quality requirements of SNI 0032:2011. Reaction kinetics for the aluminum recovery process from aluminum foil in KOH solution at room temperature 25 oC was obtained -rA = 0,006.CA. Performance test results for coagulation in domestic waste showed that synthetic potassium alum was better than commercial alum based on the decrease in turbidity parameters, Total Suspended Solid (TSS) and Total Dissolved Solid (TDS).
