“…Density is an essential parameter for surfactants due to the relevance in the application. Generally, surfactants require a density value with a small difference compared to solvent or product, to facilitate mixing and maintain the stability of emulsion (Uzwatania et al, 2017). In this research, FAME has a density of 0.876±0.002 g/cm 3 , consistent with a study of Ghazanfari et al (2017), which reported that the density of FAME from palm oil ranges from 0.843 to 0.890 g/cm 3 .…”

Most surfactants are made from petrochemicals, posing significant environmental concerns due to the non- biodegradable and non-renewable nature. To address this challenge, surfactants from biodegradable, non-toxic, and harmless materials are required, such as Fatty Acid Methyl Ester (FAME) derived from palm oil. Therefore, this research aimed to investigate the effect of reaction tempetarures and durations as well as the interactions on the yield of FAME surfactants. The characteristics of the highest yield of FAME surfactants were also examined, including HLB (hydrophilic-lipophilic balance) value, surface tension, CMC (critical micelles concentration), density, and pH values. The study was conducted using Completely Randomized Factorial Design with three (3) factors, namely temperature (50 and 60 °C), reaction duration (60, 90, and 120 minutes), and the interaction. The results showed that the highest yield of 82.43% was produced at an interaction reaction temperature of 60 °C and a duration of 120 minutes. The characteristics of surfactants obtained were HLB value of 5.47, surface tension of 30.49 dyne/cm, capable of reducing surface tension by 73.20% (from 72.80 to 19.52 dyne/cm), CMC, density and pH values of 1.50% (v/v), 0.8757 g/cm 3 , and 6.86, respectively. These characteristics suggested that FAME has the potential for application as a water-in-oil (w/o) emulsifier. Moreover, the results could be applied to produce biodegradable surfactants using tropical oils through easy and simple technology.

“…Foam stability is achieved through the presence of foaming agents (surfactants). These foaming agents are adsorbed at the interface between phases and trap gas bubbles, resulting in stability [14]. The highest foam stability value was 83.53% obtained by sample F5 with a kaolin concentration of 25% and a sucrose laurate ester concentration of 4%.…”

Kaolin solid soap is one of the soaps that can be used to remove heavy dirt (Najis mughalladzah). Sucrose esters are a unique group of emulsifiers that are non-ionic surfactants and completely biodegradable. They are obtained by the transesterification of methyl ester with sucrose. This research aims to obtain the best concentration of sucrose ester and kaolin clay and to know the characteristics and quality of soil soap. Soap was made by finding the suitable concentration for the ingredients used to make soap based on Islamic Sharia law, where the amount of soil based on the edict (fatwa) of the Ulama Council is a minimum of 5 In this study, variations in the concentration of sucrose ester used were 2, 4, and 6%, while the concentrations of kaolin clay were 20, 25, and 30%. This research used a completely randomized design (CRD) with nine treatments and three replications. Observations of the soil soap bar include pH, foam test, hardness level, moisture content, free fatty acids, and organoleptic tests. The best formulation of soil soap based on organoleptic test results is soap with a concentration of 25% kaolin and 4% sucrose ester.

“…pH sangat penting dalam proses pemilihan GE terbaik, karena pH yang terlalu asam dapat merusak mesin dan dapat menyebabkan korosi. Sebaiknya pH surfaktan yang dipilih adalah 7-9 (Uzwatania et al, 2017).…”

Peningkatan kapasitas produksi biodiesel menyebabkan meningkatnya produksi gliserol. Salah satu cara alternatif untuk meningkatkan nilai ekonomi gliserol adalah melalui esterifikasi gliserol menjadi surfaktan, yaitu gliserol ester (GE). Penelitian ini bertujuan melakukan sintesis GE berbasis asam oleat sawit dengan waktu reaksi 180 menit menggunakan katalis p-toluenesulfonic acid (PTSA). Suhu sintesis yang digunakan, yaitu:140, 160, 180, dan 240°C. Hasil uji ANOVA dan Duncan (α = 0,05) menunjukkan bahwa suhu sintesis berpengaruh nyata pada rendemen, angka asam, dan viskositas. Proses sintesis GE optimum diperoleh pada suhu sintesis 160°C dengan nilai rendemen GE sebesar 95,66%, pH 7, nilai angka asam 11,28 mg KOH/g sampel, viskositas kinematis 75,76 cst, dan densitas 0,944 g cm-3. Suhu sintesis 160°C, 180°C, dan 240°C menghasilkan rendemen yang tinggi, berkisar 95,66-97,07% dan tidak berbeda nyata antara ketiganya. Analisis menggunakan metode Analytical Hierarchy Process(AHP) juga menghasilkan suhu terbaik untuk sintesis GE adalah 160°C. Produk GE yang terbentuk mengandung gugus ester, asam karboksilat, dan alkohol yang muncul pada 1240,41-1739,62 cm-1.[Kata kunci: biodiesel, esterifikasi, katalis PTSA, surfaktan]
