Abstract
ABSTRAK
Minyak goreng yang sudah berulangkali dipanaskan akan berwarna hitam dan mengandung logam-logam berat. Untuk meremajakannya diperlukan teknologi alternatif yang mampu mereduksi logam berat pada minyak goreng bekas. Salah satunya adalah Membran PMC yang digunakan sebagai filter. Membran di uji sifat fisis (debit aliran, kerapatan porositas) dengan variasi ukuran Mesh dan komposisi karbon aktif tempurung kelapa. Matrik berasal dari campuran 0.3 gr PEG, 5 ml PVA, dan 5 ml Aquades. Filler berupa serbuk karbon aktif berasal dari limbah tempurung kelapa. Membran di buat dengan variasi ukuran mesh 60, 100, 120 mesh dan komposisi 1, 3, dan 5 gr. Karbon aktif diperoleh dari ektraksi tempurung kelapa dengan teknik pemanasan (furnace) pada temperatur 500o C dan aktifasi kimia dengan larutan H3PO4 5 M. Penyaringan terbaik ditunjukkan membran dengan penambahan karbon aktif 5 gram 120 mesh yang memiliki efektifitas penyaringan minyak goreng bekas paling baik dan adsorbsi logam berat paling maksimal. Debit aliran semakin meningkat dengan nilai 0.0333 (ml/menit) dan kerapatan membran semakin kecil 0.95534 (gr/cm) dengan porositas 0.39 %. Hasil AAS menunjukanlogam Cu mengalami penurunan kadar logam sebesar 0.0819 mg/L dan logam Fe 0.0285 mg/L. Membran ini merupakan membran mikrofiltrasi dengan rata-rata pori-pori 160.4 nm yang mampu mereduksi partikel dan bakteri dengan ukuran 400 nm hingga 2 µm.
ABSTRACT
The used edible oil that has been heated repeatedly turns black and contain heavy metals. to filter it, it is needed alternative technologies that can reduce heavy metals in used edible oil. One of them is PMC membrane technology which used as filter. It’s tested physical properties such as (flow rate, density, porosity) by Mesh size variation and the additional of coconut shell activated carbon. Matrix derived from a mixture of 0.3 g PEG, 5 ml of PVA, and 5 ml distilled. Filler in the form of powder activated carbon derived from coconut shell waste. Membrane is made by mesh size variation 60, 100, 120 mesh and the composition of 1, 3, and 5 gr. Activated carbon is derived by coconut shell extraction with heating technique (furnace) at a temperature of 500 oC and a chemical activation with solvent H3PO4 5 M. The best filtration indicated by membranes with the addition of 5 grams of activated carbon which has a 120 mesh that has the effectiveness of best filtering used cooking oil and purest heavy metal adsorption. Discharge is being raised with the value of 0.0333 (ml/min) and density of the membrane smaller 0.95534 (g/cm) with porosity 0.39 %. AAS results showed Cu decreased of metal levels in the mount of 0.0819 mg/L and Fe 0.0285 mg/L. This membrane is a microfiltration membrane with an average of pores 160.4 nm that was able to reduce the particles and bacteria with size 400 nm to 2 µm.
