ABSTRAK
Adsorpsi merupakan salah satu metoda yang dapat digunakan untuk menanganimasalah limbah emulsi minyak solar.Pada penelitian ini digunakan adsorbenadmisel zeolit HDTMA-Br teradsolubilisasi polimetil metakrilat (PMMA) untukdemulsifikasi dan adsorpsi solar. Kondisi optimum pembuatan model limbahemulsi solar adalah konsentrasi SDS 0,002 M, perbandingan minyak : air yaitu5x10-4:1, kecepatan pengadukan 450 rpm selama 15 menit. Hasil uji kestabilanemulsi minyak dalam air dengan turbidimeter didapatkan nilai turbiditas 388 NTUdan uji ukuran partikel dengan PSA didapatkan 337,9 nm. Pembuatan adsorbenzeolit admisel-PMMA dilakukan dengan melalui tahapan: adsorpsi surfaktanHDTMA-Br pada permukaan zeolit membentuk admisel, mengadsolubilisasikanmonomer metil metakrilat (MMA) ke dalam admisel dan polimerisasi MMAdengan menambahkan inisiator kalium persulfat (K2S2O8). Keberhasilanpembentukan zeolit admisel-PMMA tersebut dibuktikan dengan spektrofotometerFTIR. Analisis kuantitatif adsorpsi minyak solar oleh zeolit admisel-PMMAdigunakan metode ekstraksi gravimetri dan adsorpsi SDS menggunakanspektrofotometer UV-Vis. Kondisi optimum adsorpsi adalah massa adsorben 0,6gram, waktu pengadukan 45 menit dan pH 7,3. Kapasitas adsorpsi optimumuntuk solar adalah 97,46 mg/gram dan untuk SDS 16,52 x 10-4 mmol/L.

ABSTRACT
Adsorption and demulsification is the one solution to handle waste diesel oilemulsion. Therefore, in this research, applications of zeolite admicelle HDTMA -Br adsolubilized polymethyl methacrylate (PMMA) for demulsification andadsorption waste of diesel oil emulsion. The optimum condition of fuel emulsionwaste includeof SDS concentration of 0.002 M, the variation ratio of oil:water is5x10- 4:1, stirring 450 rpm for 15 minute. Result of stabilized emulsion withturbidimeter is 388 NTU as amount of turbidity and 337,9 nm of particle test withPSA. Making adsorption zeolite admicelle-PMMA through the stages ofHDTMA-Br surfactant adsorption on the surface of the zeolite, adsolubilizedmethyl methacrylate monomer into the zeolite admicelle and polymerizationinitiator admicelle by adding calium persulfate (K2S2O8).The success of themodifications proved by FTIR spectrophotometer showed that the spectrum ofPMMA has appeared on zeolite admicelle-PMMA. The efficiency of zeoliteadmicelle PMMA forming was proven by FTIR spectrophotometer. On the otherhand, quantitative analysis of fuel emulsion adsorption by zeolit was usinggravimeter extraction method while SDS adsorption was using UV-Visspectrophotometer. The optimum condition of adsorption are 0,6 gram adsorbentmass, 45 minutes agitation time and pH 7,3. Optimum adsorption capacity of fuelis 97,46 mg/gram and 16,52 x 10-4 mmol/L for SDS.
