“…This notable presence of methyl oleate is significant as it contributes to the improvement of low-temperature performance and also has a positive impact on the oxidation stability of biodiesel [29]. The methyl oleate content in this study was higher than the 38.108% castor oil biodiesel content [30] and palm oil 42.72% [31]. This shows that biodiesel B100 has good quality to be developed further.…”

The study objective is to investigate the combustion characteristics of Callophyllum inophyllum fuel in presence of a magnetic fields. To conduct the experiment, a bunsen burner was utilized, with fuel and air being dispensed via a syringe pump and compressor, both regulated by a flowmeter. The fuel and air pipes were heated to 532.15 (K) to facilitate fuel evaporation. The equivalent ratio of 0.5, 1, and 1.5 was adjusted to control air discharge and fuel. An 11,000 gausses artificial magnet was used, with N-S, N-S, N-N, and S-S being the various magnetic pole configurations. The study found that the magnetic field can enhance combustion quality by affecting the molecules involved in the combustion process. The magnetic field's force also intensifies the movement of O2, making it more energetic. As O2 travels from the North Pole to the South Pole through the combustion reaction zone, it quickens the oxidation-reduction process and curtails diffusion combustion. The red color's intensity diminishes with the magnetic field's effect, indicating this phenomenon. When a magnetic field is applied, the polarity of C.inophyllum biodiesel fuel becomes highly favorable. The triglyceride carbon chain bonds become unstable, and the van der Walls dispersion forces are weakened, which facilitates easier O2 binding to the fuel, resulting in more efficient combustion. An increase in the laminar burning velocity value can be noticed when exposed to a magnetic field.

“…Methyl oleate is a free fatty acid that plays an important role in biodiesel because it can improve low-temperature performance and has a positive impact on the oxidation stability of biodiesel [34]. The content of methyl oleate in this research was higher than the content of biodiesel in castor oil (38.108%) and palm oil (42.72%) [35]. This shows that CIME biodiesel has good quality for further development.…”

Nyamplung (Calophyllum Inophyllum) is an environmentally friendly alternative fuel that can be used to replace the consumption of fossil fuels. The purpose of this experiment was to analyze the effect of magnetic fields on the premixed flame of biodiesel from Calophyllum Inophyllum, the experiments were carried out on a bunsen burner. Fuel evaporation uses a temperature of 473 K and the equivalent ratio used is between ϕ 0.7; 0.8; 0.9; 1.0; 1.1 and 1.2. This experiment used a modified magnet that has magnetic force in 11.000 gausses with magnetic variations N-S, S-N, N-N, and S-S. Experiments revealed that magnetic fields have a significant effect to increase the value of laminar flame speed on magnetic variations point at S-S 3.8%; N-N 4.8%; S-N 17.09%, and the highest laminar flame speed were at point N-S 20.7%. The enhancement value of laminar flame speed indicated more optimum combustion processes. The magnetic fields can influence the O2, and H2O and change the orientation of the hydrocarbons which makes it easier for O2 and fuel to carry out the oxidation process, resulting in more optimal combustion.

“…Methyl oleate is a free fatty acid which plays an important role in biodiesel because it has a positive impact on the oxidation stability of biodiesel and is good at low temperatures [34]. Methyl oleate in calophyllum inophyllum biodiesel has a higher percentage compared to the methyl oleate content in castor oil biodiesel of 38.108% and palm oil 42.72% [35,36]. The high methyl oleate content indicates that calophyllum inophyllum biodiesel has good quality so it has the potential to be developed in depth and can be produced commercially.…”

The problems facing the world today are limited fossil fuels and increasing global warming due to fuel emissions. Therefore, there is a need to transition from fossil energy to alternative energy that is environmentally friendly and renewable. Biodiesel is an alternative material that can be used as a substitute for diesel fuel. This research aims to improve the combustion quality of calophyllum inophyllum biodiesel using the magnetic field influence method. The combustion test method uses a Bunsen burner and variations in magnetic strength of 4000 gauss, 8000 gauss and 12000 gauss are given. The equivalent ratios used in combustion analysis are 0.6:1, 0.7:1, 0.8:1, 0.9:1, 1:1, 1:1.1, and 1:1.2. The fuel and air flowing in the Bunsen pipe are heated to a constant temperature of 250°C for the fuel evaporation process. Then the resulting flame was analyzed for its combustion characteristics with RGB color variables, laminar burning velocity, and flame height. The research results show that the stronger the magnetic field effect, the more optimal the combustion quality will be. This is indicated by the increasingly strong magnetic field effect exerted on the flame, causing the red color intensity to decrease, the laminar burning velocity to increase, and the flame height to decrease. This is because the magnetic field can influence the movement of O2 molecules and cause a change in the orientation of the hydrocarbon from para to ortho. As a result, diffusion combustion becomes minimal and the combustion reaction becomes faster.
