Abstract

Cooking oil is one of basic food consumed by the whole society. One industry that many use a lot of cooking oil is krecek rambak industries at the Segoroyoso, Pleret, Bantul, Yogyakarta. One waste has not managed well in the rambak krecek industries is jelantah oil. The purpose of this research is to get cooking oil regenerate. The cooking oil regeneration done obtained from purification of jelantah oil using adsorbent (carbon active).One of the materials can be used as a carbon active is cassava skin. The skin cassava obtained from the waste of the merchant food. Making carbon active waste skin cassava done with chemicals process because the process simpler than with physics process. In this research, the longer time of submersion jelantah oil with adsorbent then the lesser levels of free fatty acids and peroxides in jelantah oil. The levels of free fatty acids and peroxide value optimally on the day to 6 submersion of 6,3835% and 15,6179Ml.eq/kg.

Abstract

Salah asatu upaya yang dapat dilakukan untuk mengatasi masalah limbah cair industry laundry adalah dengan menggunakan metode Fytoremediasi. Salah satu metode yang prinsip kerjanya memanfaatkan simbiosis tanaman dengan mikroorganisme diarea zona rhizosfer tanaman yang mampu merombak senyawa senyawa pencemar menjadi ion ion yang dapat diserap oleh tanaman. Penelitian ini bertujuan untuk mengetahui sejauh mana tanaman Typha latifolia dan tanaman Cyperus alternifolius dapat menurunkan konsentrasi BOD pada limbah cair industry laundry, untuk selanjutnya dilakukan analisis untuk mengetahui seberapa banyak masing masing tanaman tersebut dapat digunakan dalam penyisihan limbah cair industri laundry (BOD) pertanaman perluas lahan.Dari hasil penelitian dan analisis yang dilakukan, dapat diketahui baik tanaman Typha latifolia maupun tanaman Cyperus alternifolius sama sama efektif dalam menurunkan konsentrasi limbah BOD pada industry laundry sebesar 99% penurunan. Dari hasil perhitungan dengan menggunakan persamaan loading rate BOD dapat diketahui nilai loading BOD perluas lahan pertanaman (BOD/A/tanaman)adalah 2035,4mg/24m2 (4) yakni sebesar 21,2 mg/m2/tanaman.
