Abstract

Tujuan dari penelitian ini adalah mempelajari pengaruh konsentrasi surfaktan dan kandungan air terhadap karakteristik emulsi solar-air sebagai bahan bakar alternatif pada mesin diesel. Karakteristik tersebut dinilai sebagai kestabilan emulsi solar-air. Tiga tahapan dilakukan dalam penelitian ini yaitu persiapan larutan surfaktan, proses emulsi solar-air-surfaktan, dan analisa dan pengamatan. Variabel penelitian ini adalah variasi kondisi sonikasi, jenis surfaktan, konsentrasi surfaktan, dan kandungan air. Karakteristik emulsi solar-air diamati menggunakan analisa densitas, viskositas dan visualisasi (warna). Hasil pengamatan pada persiapan emulsi solar-air dengan sonikasi menunjukkan emulsi paling stabil adalah sonikasi tanpa menggunakan pulser dan dengan penambahan pengadukan. Selain itu emulsi lebih stabil dengan penambahan Carboxy Methyl Cellulose (CMC) sebagai co-emulsifier atau disebut juga stabilizer. Pengamatan variasi jenis surfaktan dilakukan pada tiga surfaktan yaitu Alkyl Benzene Sulfonate (ABS), Sodium Lauryl Sulfate (SLS), dan Sorbitan Monooleate (Span 80). Emulsi paling stabil didapatkan pada Span 80 yang memiliki nilai Hydrophilic Lipophilic Balance (HLB) pada kisaran untuk emulsi solar-air, yaitu 4. Pengamatan konsentrasi surfaktan menunjukkan hasil terstabil adalah pada konsentrasi 2% diikuti oleh konsentrasi 1%, 0,5%, dan 0,1%. Pengamatan kandungan air menunjukkan hasil kandungan air 30% volume paling lama kestabilannya dibandingkan kandungan air 10% dan 20% terhadap volume. ============================================================ The aim of this study is assessed the effect of loading of surfactant and water to diesel-water emulsions characteristic as alternative fuel to be used in diesel engine. Those characteristics will assessed from the stabilization of diesel-water emulsions. The steps of this experiment are preparing for surfactant liquid, producing of diesel-water-surfactant fuel emulsion, and analyzed and assessed. The experiment variables are variations of sonication, surfactant loading, and water loading. Characteristic of diesel-water emulsion determined by the density, viscosity, and visualization (color) analyses. Results showed that the prepared water-oil emulsion with sonication exhibited the best stabilization is sonication process without pulser and with an extra stirred. Besides that, stabilization of emulsion better with Carboxy Methyl Cellulose (CMC) as co-emulsifier also called stabilizer. Experiment used three kinds of surfactant, there are Alkyl Benzene Sulphonic acid (ABS), Sodium Lauryl Sulfate (SLS), dan Sorbitan Monooleate (Span 80). Emulsion with Span 80 exhibited the best stabilization which have Hydrophilic Lipophilic Balance (HLB) in ranged for water-diesel emulsions, is 4. The surfactant loading assessed 2% is highest stabilization followed by surfactant loading 1%, 0,5%, and 0,1%. At water loading observation has been found that 30% water loading by volume given the slowest stabilization compared with 10% and 20% water loading by volume.
