Surfactant which is used as raw emulsifier in an industry activity such as Sodium Lauryl Sulfonate is a raw material import, it is petroleum derivative which is not renewable and may cause pollution to the environment, because it is not degraded and are carcinogenic. The purpose of the research is to compare the characteristics of the Quaternary methyl ester sulfonat (MES) and Sodium Lauryl Sulfonat (SLS) as emulsifier. First, make the MES by filtering and eliminating fatty acids of palm oil, then process the MES with enzymatic method become methyl ester, then react it in sulfonation and metanolization process, and also neutralized with NaOH. Next, the MES experiment is compared with SLS and existing MES in the market. The results show that surfactants MES experiment has value hidrofil lipofil balance (HLB) interfacial tension and emulsion stability greater than MES in the market and SLS. And the surface tension of MES experiment is larger than MES in the market, but smaller compared to SLS.ABSTRAKSurfaktan yang digunakan sebagai bahan baku emulsifer dalam aktivitas suatu industri pada saat ini seperti Sodium Lauril Sulfonat  merupakan bahan baku import yang merupakan turunan dari minyak bumi, dengan sifat tidak dapat diperbaharui dan dapat menimbulkan pencemaran terhadap lingkungan karena tidak mudah terdegradasi serta bersifat karsinogenik. Metil ester sulfonat dari bahan minyak sawit merupakan surfaktan dengan sifat mudah terdegradasi yang perlu diketahui karakteristiknya. Penelitian bertujuan untuk membandingkan karakteristik surfaktan metil ester sulfonat (MES) dan Sodium Lauril Sulfonat (SLS) sebagai bahan emulsifier. Mula-mula dilakukan pembuatan MES dengan cara menyaring dan menghilangkan asam lemak minyak sawit terlebih dahulu, kemudian diolah menjadi metil ester secara enzimatis, lalu direaksikan secara sulfonasi dan metanolisis, serta dinetralkan dengan NaOH. Selanjutnya MES hasil percobaan dibandingkan dengan SLS dan MES yang ada dipasaran. Hasil penelitian menunjukkan bahwa surfaktan MES memiliki nilai hidrofil lipofil balance (HLB) tegangan antar muka dan stabilitas emulsi lebih besar apabila dibandingkan dengan MES di pasaran dan SLS, kecuali nilai stabilitas emulsi antara MES dan SLS sama.

Konsumsi minyak bumi mengalami peningkatan dari tahun ke tahun, sementara produksinya cenderung mengalami penurunan. Produksi minyak bumi dapat ditingkatkan dengan oil recovery. Sejak tahun 1980, teknik Enhanced Oil Recovery (EOR) dengan menggunakan surfaktan sebagai penginjeksi (surfactant flooding) merupakan salah satu teknik yang paling berhasil untuk meningkatkan produksi minyak. Surfaktan dapat dibuat dari bahan alami, salah satunya dari minyak jarak pagar. Tujuan dari percobaan ini adalah untuk mengkaji pengaruh waktu reaksi dan pengaruh penambahan metanol terhadap metil ester sulfonat (MES, surfaktan) yang dihasilkan dalam operasi sulfonasi. Surfaktan yang diperoleh kemudian diaplikasikan dalam proses EOR. Proses pembuatan MES dari minyak biji jarak dilakukan melalui 2 tahapan yaitu proses esterfikasi dan transesterifikasi dengan katalis batu dolomite. Metil ester (ME) yang diperoleh kemudian disulfonasi untuk mendapatkan MES. Konsentrasi surfaktan anionik dalam produk dianalisa dengan spektrofotometer. Hasil penelitian menunjukkan bahwa MES yang memiliki kandungan surfaktan anionik paling tinggi diperoleh pada waktu reaksi 90 menit dan penambahan metanol dengan konsentrasi 40%wt yaitu sebesar 55,464 mg/L. Uji kompatibilitas didapatkan larutan berwarna keruh (koloid), sedangkan tegangan antarmukanya sebesar 17,71 dyne/cm dan tegangan antarmuka pada suhu 80oC adalah 26,57 dyne/cm. Petroleum consumption has increased from year to year, while production tends to decline. Petroleum production can be increased by oil recovery. Since 1980, the Enhanced Oil Recovery (EOR) technique using surfactants as injectors (surfactant flooding) is one of the most successful techniques for increasing oil production. Surfactants can be made from natural ingredients, one of them from jatropha oil. The purpose of this experiment was to examine the effect of reaction time and the effect of adding methanol to methyl ester sulfonate (MES, surfactant) produced in sulfonation operations. The surfactants obtained are then applied in the EOR process. The process of MES production from castor oil is carried out through 2 stages, namely esterfication and transesterification with dolomite catalyst. Methyl esters (ME) were obtained then sulfonated to obtain MES. The concentration of anionic surfactants in the product was analyzed by a spectrophotometer. The results showed that the MES which had the highest anionic surfactant content was obtained at the reaction time of 90 minutes and the addition of methanol with a concentration of 40% wt was 55.464 mg/L. Compatibility test obtained colloidal colored solution (colloid), while surface tension was 17.71 dyne/cm and surface tension at 80oC was 26.57 dyne/cm.

The synthesis of biodiesel expressed as fatty acid methyl ester (FAME) were studied to achieve an economic and practical method for utilization of used cooking oil (UCO). UCO samples with the acid value of more than 80 mgKOH/g mixed with methanol were heterogeneously catalyzed by solid aminosulfonic acid under some conditions . The conversion of UCO into FAME was 86.0% at the reaction time of 2 hours, mole ratio of methanol to UCO of 5:1, showing much higher catalyzed activity of solid aminosulfonic acid. the samples of FAME prepared from UCO was analyzed by GC/MS and the results showes that the majority of biodiesel has fatty acid methyl esters of carbon lengths from C14–C24, with an average of C18 methyl ester.

SummaryComparative studies have been made of the esterase activity of plasmin and the streptokinase-activator of plasminogen on a variety of substituted arginine and lysine esters. Human plasmin preparations derived by different methods of activation (spontaneous in glycerol, trypsin, streptokinase (SK) and urokinase) are similar in their esterase activity; this suggests that the molecular structure required for such esterase activity is similar for all of these human plasmins. Bovine plasmin, on the other hand, differs from human plasmin in its activity on several of the substrates studied (e.g., the methyl esters of benzoyl arginine and tosyl, acetyl and carbobenzoxy lysine), a finding which supports the view that molecular differences exist between the two animal plasmins. The streptokinase-activator hydrolyzes both arginine and lysine esters but the ratios of hydrolytic activity are distinct from those of plasmin and of other activators of plasminogen. The use of benzoyl arginine methyl ester as a substrate for the measurement of the esterase activity of the streptokinase-activator is described.

In the manufacture of detergents still using surfactants (which serves as an emulsifier) of crude oil in the form of the AS. (alcohol sulfate) and LAS (linear alkylbenzene sulfonate), where this type of surfactant cannot be degraded by microorganisms when discharged into the environment, causing environmental pollution. Methyl ester sulfonate surfactant is an anionic surfactant which has a composition of C16 - C18 fatty acids are capable of acting against nature deterjensinya, while the C12 - C14 fatty acids contribute to the foaming effect. The purpose of this study was to look for the formulation of methyl ester sulfonate (MES) the right to produce a good detergent by using materials such as methyl ester sulfonate surfactant self-made, methyl ester sulfonate and sodium lauryl market Ester Sulfate (SLS) with a concentration of 15 %, 20 % and 25 %. Detergent results of the study have high detergency ( net ) compared with the detergency of detergent commercial, have a stable emulsion stability, the stability of the foam/foam detergent power made from methyl ester sulfonate surfactant produces less foam, compared with a detergent made from SLS and surfactant SNI 06-4075-1996 standards.
