Abstract

Minyak goreng pada umumnya digunakan untuk memasak dan biasanya bisa digunakan hingga 3-4 kali penggorengan. Minyak goreng yang telah dipakai (minyak jelantah) akan menjadi barang buangan atau limbah dari rumah tangga dan pabrik industri penggorengan, jika tidak didaur ulang akan menjadi limbah yang mencemari lingkungan. Minyak jelantah dapat dimanfaatkan kembali dengan proses pemurnian yang selanjutnya dapat diolah menjadi bahan baku industri non pangan seperti sabun. Minyak jelantah mempunyai kandungan asam lemak bebas (ALB) yang cukup tinggi. Prosess pemurnian minyak jelantah dapat dilakukan dengan menggunakan ampas tebu sebagai adsorben untuk menurunkan kadar ALB pada minyak. Penelitian ini bertujuan untuk membuat sabun padat dari minyak jelantah yang berasal dari buah kelapa dan jagung.Kemudian hasil dari penelitian ini dibandingkan dengan standar SNI. Pengamatan dilakukan atas parameter yang meliputi: kadar air pada minyak, kadar asam lemak bebas (ALB), berat sabun yang dihasilkan, kadar air pada sabun, derajat keasaman (pH), dan tinggi busa. Hasil dari penelitian yang telah dilakukan menunjukan sampel sabun padat yang diuji memenuhi standar SNI NO 06-3532-1994 yang telah ditetapkan. Namun,kadar air pada sabun padat masih kurang baik karena melebihi batas maksimal SNI.

Abstract

Salah satu parameter yang menentukan kualitas pencemaran air adalah kandungan logam berat seperti tembaga (Cu) dan Besi (Fe). Paparan logam berat dapat mengakibatkan penyakit kanker pada manusia, apabila dikonsumsi secara terus-menerus. Oleh karena itu, logam ini perlu untuk diolah terlebih dahulu sebelum dibuang ke air permukaan atau pun sebagai air bersih. Pada penelitian ini telah diproduksi adsorben dari kertas koran bekas. Metode adsorpsi dipilih karena metode ini merupakan proses yang sederhana dan efektif untuk mengurangi kadar logam berat. Sedangkan kertas koran bekas memiliki kandungan selulosa yang telah lama diketahui mempunyai potensi yang cukup signifikan karena kemampuan adsorpsi nya .Penelitian ini meliputi dua tahap yaitu tahap pertama adalah pembuatan adsorben dari kertas koran bekas. Kertas koran bekas dilarutkan dalam larutan natrium hidroksida 10% untuk mengurangi berbagai kotoran seperti debu dan tinta. Pada tahap kedua, parameter yang telah diujikan adalah dosis adsorben dan waktu kontak. Setelah tahap adsorpsi selesai, larutan disaring dan dianalisa dengan menggunakan Spektrofotometer Serapan Atom (AAS). Dari hasil penelitian persen removal Cu (II) tertinggi 99,31 % dan Fe (II) 99,99% dan dari persamaan adsorpsi Ishoterm Langmuir diperoleh kapasitas adsorpsi maksimal (Q) pada 2182 μg/g untuk Cu (II) dan 1552 μg/g untuk Fe (II).

Abstract

Turmeric is widely used as a herbal medicine, food preservation and food coloring. However, food industries have less interest to utilize turmeric as a food coloring due to its spesific aroma. The objective of this research was to obtain the proper method to eliminate the turmeric’s spesific aroma. The experimental methods consisted of 3 stages, namely distillation (A1) and non-distillation (A2) methods which then was extracted by maceration method with the addition of 96% ethanol (B1), acetone (B2) and ethanol 96% + acetone (B3) as stage 1; with (C1) and without heating (C2) as stage 2; and the addition of 3% acetic acid and 3% citric acid as stage 3. The results of stage 1, 2, and 3 were the spesific aroma of turmeric tend to be weak when use the distillation and maceration with 96% ethanol where the curcumin content was 0.50%, and with the addition of 3% acetic acid which have a brighter color, respectively. The color analysis showed that the color by adding 3% acetic acid has CIE b* (yellow) of 66.85 with pH of 3.24. So, the proper method for eliminating the turmeric’s spesific aroma was distillation process then followed by extraction using 96% ethanol and adding 3% acetic acid to increase the color brightness and homogeneity.
