The development of bio degreaser made from palm oil surfactant aims to substitute bio degreaser made from petroleum surfactant which is less environmentally friendly. The development was carried out by formulating palm methyl ester sulfonate (MES) surfactant with oxalic acid as metal or non-metal cleaning agent. The purpose of this study was to obtain the best concentration of oxalic acid in the bio degreaser formulation. The concentrations of oxalic acid tested were 7, 8, and 9%. The best concentration of oxalic acid was determined based on the results of characteristic tests and detergency tests, namely 7% oxalic acid concentration. The resulting bio degreaser product has a pH of 1.6; viscosity 1.39 cp; specific gravity of 1.012; surface tension 32 dyne/cm and detergency power 84%. Furthermore, the resulting bio degreaser was added with Diethanolamioda (DEA) surfactant. The purpose of adding DEA surfactant is to increase the pH and lower the surface tension. The formulation results showed an increase in pH from 1.6 to 3.2 and a decrease in surface tension from 31.97 dyne/cm to 28.70 dyne/cm. In addition, there was an increase in viscosity from 1.39 cp to 1.62 cp and specific gravity from 1.012 to 1.018.

Methyl ester sulfonate derived from mahogany (<em>Swietenia macrophylla</em> K.) oil has been characterized. The research began by synthesizing mahogany methyl ester (ME) in 4 stages: pressing, degumming, esterification, and transesterification. The next process was synthesizing methyl ester sulfonate (MES) also in four stages: sulfonation, bleaching, neutralization, and drying. The reactant for MES synthesis in this study was H<sub>2</sub>SO<sub>4</sub> with a mole ratio of 1:6 and variations in the concentration of H<sub>2</sub>SO<sub>4</sub> (70%, 75%, 80%, 85%, and 90%) as well as variations in the duration of sulfonation (45, 60, 75, 70, and 105 minutes) to determine the characteristics of the synthesized MES including density, acid number, and emulsion stability. The effect of the combination of treatment variations was analyzed using the two-way ANOVA test and the least significant difference (LSD) test. This research showed that MES from mahogany seed oil from a combination of variations in treatment has a density ranging from 0.91 to 0.97 g/mL where the LSD test at α = 0.05 produces three different MES density groups due to variations in the concentration of H<sub>2</sub>SO<sub>4</sub> namely A (70 % and 75%), B (80% and 85%), and C (90%). The resulting MES acid numbers ranged from 4.69 ‒ 17.74 mgKOH/g sample with three different groups of MES acid numbers due to variations in the concentration of H<sub>2</sub>SO<sub>4</sub>, namely A (85 and 90%), B (75% and 80%), and C (70%). The stability of mahogany oil-based MES emulsion ranged from 0.000 ‒ 0.975 and two different MES emulsion stability groups were obtained due to variations in the concentration of H<sub>2</sub>SO<sub>4</sub>, namely A (80% and 85%) and B (70%, 75%, and 90%). FTIR spectrophotometer showed the presence of S=O groups at wavenumber 1172 cm<sup>-1</sup> and S‒O groups at wavenumbers 972.12 cm<sup>-1</sup> and 879.54 cm<sup>-1</sup> proved that MES was successfully synthesized.

The emulsified feedstock technique is to improve the performance of products by using the micro-explosion phenomenon of emulsion. However, an obstacle to some applications of this technology is the contradiction between emulsion stability and micro-explosion intensity. For the first time, adding water-soluble polymers was proposed to solve this problem. Two polymers of xanthan gum (XG) and nonionic polyacrylamide (NPAM) were investigated and the results show that micro-explosions have five forms. As one of these five forms, the intensity of optimal micro-explosion is three orders of magnitude higher than other forms, and adding 0.5% XG increases the probability of optimal micro-explosion from 0% to 60% due to the low surface activity, strong thickening and pseudoplasticity of XG solutions. By contrast, NPAM does not promote micro-explosion because of its strong surface activity. Finally, a new mechanism for micro-explosions related to surface tension, interfacial tension and viscosity is proposed.

Abstract This paper aims to investigate the tribological friction using the Stribeck curve lubrication regime using an alternative source of biodiesel. Replacement of current usage of fossil fuels is essential, therefore, it is important to develop a proper recycling, renewable and sustainable product that reduces global warming. Biodiesel also known as Fatty Acid Methyl Ester (FAME), is biodegradable, produced from a renewable source, non-toxic, and produces a minimum greenhouse gas emissions. To reduce raw material cost, waste cooking oil is one of the most suitable replacements of vegetable oil for biodiesel synthesis. Rheological behavior of Waste Palm Methyl Ester (WPME), such as kinematic viscosity, density, and acid value, was measured based on EN14214 and compared with Palm Methyl Ester (PME). The friction performance of WPME was evaluated using a pin on the disc tribometer machine. The influence of different operating conditions such as loads at 1kg, 2kg, 3kg and 4kg and sliding velocity range from 0.00625 m/s to 4 m/s were optimized in this study. The preliminary result shows significant changes on the Stribeck curve concerning the sliding speed and also loads. It is found that as for the same entrainment velocity and surface roughness, a higher load will initiate a higher temperature, thus lead to decreasing the viscosity and coefficient of friction. In summary, WPME is highly considered as a potential waste that can replace the current energy source.
