Abstract

Waste cooking oil produced by households and industries. The use of waste cooking oil be fuel, soap, floor cleaner, and candles have been developed. The use of waste cooking oil must be through purification step. A method of purification oil also have been developed, but the methods already there still managed to take optimal results. This research for development of previous studies, so results of this oil can be directly used to a different product with economic value. This research condist of 2 stages, treatment process and purification process. The treatment process using bentonite and potassium hydroxide (KOH). The purification process using purification oil instrument (capacity 5 liters) fitted with zeolite, filter paper and cotton a bandage. The purification of uses adsorption method for 24 hours. Purification process happened due to differences in weights molecules or porocity causeing some molecules bound stronger on the surface  of on the molecular. The use of KOH and bentonite to treatment process is very effective. While purification oil instrument can filer waste cooking oil that q brown and smelling become clear yellow, no longer smelling and the surface smooth. This research can decrease the free fatty acid  58% and peroxide 47,6%.

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.
