Pemurnian Minyak Jelantah Menggunakan Adsorben Berbasis Cangkang Telur

Abstract

Mengkonsumsi telur ayam di Malang tahun 2011 sebesar 986. 794 ton serta cangkang telur ayam jadi salah satu limbahnya. Tiap cangkang telur mempunyai 10.000 - 20.000 pori-pori sehingga diperkirakan bisa meresap sesuatu solut serta bisa digunakan bagaikan adsorben. Disamping itu isi terbanyak cangkang telur merupakan kalsium karbonat, dimana kalsium karbonat ini tercantum ke dalam adsorben polar. Pada riset ini cangkang telur diaktivasi secara fisika serta dimanfaatkan bagaikan adsorben buat merendahkan bilangan asam, bilangan peroksida serta kandungan air pada minyak jelantah. Proses adsorpsi minyak jelantah dicoba dengan alterasi masa adsorben 5, 6, 7, 8, 9, 10 gr serta waktu pengadukan 10, 20, 30, 40, 50 menit. Bersumber pada hasil riset diperoleh keadaan optimum untuk penyusutan bilangan asam, bilangan peroksida serta kandungan air. Bilangan asam, bilangan peroksida serta kandungan air yang diperoleh pada keadaan optimum sudah penuhi standar SNI 3741- 2013 untuk minyak goreng ialah 0, 6 miligram KOH/ gram, 10 meq O2/ kilogram serta 0, 15%.

Preparation and Characterization of Natural Zeolite Minerals to Reduce Free Fatty Acid Levels in Used Cooking Oil

“…The same thing was also obtained by [19,20,21] who carried out the purification of used cooking oil with the adsorption process using Moringa seeds as an adsorbent. The results showed that the greater the number of Moringa seeds added, the smaller the measured free fatty acid levels.…”

Characterization of Egg Shell Waste As Adsorbent for Cooking Oil Waste Purification

“…The first group did not use calcination/activation, and the second group used calcination. The calcination method is carried out by ashing the sample using a furnace at a temperature of 700 °C for 2 hours [11].…”

“…The utilization of eggshells as a filter is an effort to use eggshell waste that has been only thrown away. Eggshells have high CaCO3 (calcium) levels, which is 87%-97%, and have natural pores, so they can absorb substances that are not useful [10,11]. The research results by Niju et al [7] and Ur Rahman et al [8] provide empirical evidence that eggshell waste can be an efficient catalyst for the transesterification of used cooking oil.…”

Optimization time and mass of eggshell adsorbent in improving waste cooking oil quality

“…Variations in mass, pH, and time were carried out to determine the ability of the egg shell to absorb methyl orange solution, the best condition at a mass of 11 g with a contact time of 60 minutes at pH 1 obtained an adsorption efficiency of 41.46% [12]. The use of eggshells as adsorbents with a large mass and stirring time will improve the quality of the oil so ISSN 1907-1744 (Cetak) DOI: 10.29303/jpm.v17i5.3654 ISSN 2460-1500 (Online) that it can achieve oil in accordance with the SNI standard 01-3741-2013 [9]. Eggshells can lower acid and peroxide numbers by 91% and 58% [1].…”

“…In an effort to reduce environmental waste while increasing the economic value of eggshells, eggshells are used as adsorbents in increasing the shell of used cooking oil. The eggshell itself contains 10,000-20,000 pores containing 94% calcium carbonate which can be used as a polar absorbent [8] [9].…”
