Abstract

Minyak pelumas bekas merupakan limbah yang dihasilkan kendaraan bermotor yang jumlah buangannya sangat besar terutama dikota besar. Apabila terpapar akan membahayakan dan menyebabkan masalah dalam lingkungan.. Berbagai metode pengolahan minyak pelumas bekas seperti acid-clay, Distilasi Thin Film Evaporation–Hydrofinishing dan Pirolisi. Penelitian dilakukan untuk mengetahui konversi minyak pelumas bekas menjadi minyak serta mengetahui karekteristik produk cair yang dihasilkan. Minyak pelumas dipanaskan melalui metode pirolisis hingga mencapai suhu 2500C dengan banyak umpan 125 ml dengan variasi ratio (w/w) antara umpan dan zeolit alam 1:0 , 1:0.25, 1:0,5, 1:0.75 yang berupa batuan kecil yang telah dihaluskan sebesar 40 mesh.. Sebelum digunakan. zeolit alam terlebih dahulu diaktivasi menggunakan NaOH 10%(w/w). Cairan minyak yang dihasilkan kemudian di analisa berupa Initial Boilling Point (IBP), densitas, viskositas, flash point dan four point, specific gravity. Hasil penelitian pirolisis minyak pelumas didapat produk cair sebanyak 43,7 ml,65 ml, 77 ml dan 108,3ml. Penggunaan ratio katalis 1:0.75 menghasilkan produk cair terbanyak yaitu sebesar 108,3 ml atau 87%. Dengan karakteristsik minyak yang didapat yaitu Initial Boilling Point 185oC, berat jenis 835 kg/m3, viskositas 02.58 mm2/s 30 C ; 02.58 mm2/s 40 C, flash point 550C dan pour point. < 0 oC specific gravity 0.835. Dapat disimpulkan Pirolisis minyak pelumas bekas dengan menggunakan katalis zeolit alam dapat menghasilkan minyak dengan karakteristik produk yang dihasilkan mendekati minyak solar.

Abstract

Laboratory wastewater contains harmful compounds such as COD, TSS, heavy metals, and toxic compounds that require treatment before being discharged into the environment. Laboratory wastewater contains various hazardous pollutants that can pollute the environment if not managed properly. This study aims to evaluate the efficiency of the electrocoagulation process in the treatment of laboratory wastewater of the Chemical Engineering Study Program of PGRI University Palembang with variations in current density and reaction time. The experimental method was used by designing an electrocoagulation reactor using aluminum electrodes. The independent variables tested include current density (76.92 A/m², 87.17 A/m², and 102.56 A/m²) and reaction time of 15, 30, 60 minutes. Parameters analyzed included COD, TSS, TDS, pH, electrode consumption, and energy consumption. The results showed that the electrocoagulation process effectively reduced pollutant parameters; at a current density of 102.56 A/m² for 60 minutes, COD decreased to 63.5 mg/L, TSS to 23.52 mg/L, pH increased to 8, and turbidity reduced to 20.48 NTU. The specific energy consumption reached 18.2 kWh/m³ with an operational cost of Rp27,300/m³. Based on the analysis, the optimal current density for laboratory wastewater treatment is 102.56 A/m² with a reaction time of 60 minutes. Electrocoagulation technology is recommended as an efficient, effective, and environmentally friendly treatment method for laboratory wastewater in higher education institutions.
