“…High levels of carbon (OC), black carbon (EC/BC), ash, and heavy metals are a large contributor to emissions (Chu- Van et al, 2020). Many types of biodiesel have been studied, such as biodiesel from waste cooking oil (WCO) (Suanggana & Said, 2023;Suardi et al, 2023a;Desiyana et al, 2014;Sinaga et al, 2014), biodiesel from corn (maize) oil (Suardi et al, 2023b), biodiesel production from castor oil (Suardi et al, 2023c), biodiesel from algae (Azeez et al, 2021), and biodiesel from coconut oil (Pramitha et al, 2016). Almost all types of vegetable oils have been studied and are dominantly capable of being used as alternative fuels to substitute for hydrocarbon fuels.…”

To address the challenges faced by the government in the realm of petroleum imports, a promising strategy was adopted in the utilization of biodegradable and renewable sources of biodiesel, such as coconut oil. This research employed two distinct methodologies: Transesterification for biodiesel synthesis and a comprehensive assessment of fuel properties. Subsequently, an experimental phase assessed biodiesel within an engine environment to analysis performance metrics. Results showed that B30 (30% coconut oil, 70% diesel oil) has density of 0.850 g/cm³, B50 (50% coconut oil) at 0.861 g/cm³, and B100 (Pure coconut oil) at 0.893 g/cm³. The values differed from regional standards. As per ASTM D6751, B30 has a viscosity of 2.31 cSt, B50 3.22 cSt, and B100 is 7.02 cSt. Engine performance revealed B50 with the highest torque at 11.787 Nm, while B0 (pure hydrocarbon diesel) has a thermal efficiency of 38%. B0’s lowest SFC (Specific Fuel Consumption) is 261.12 g/kWh at 2000 watts load and 1000 rpm. Biodiesel coconut oil provided comparable power and torque (0.3% difference from B0) but consumed more fuel (21.6 % higher usage than B0). Keywords: Biodiesel, Coconut oil, Engine performance, Fuel properties, Transesterification.

“…Due to the unstable working environment of the ship's engine due to the influence of waves, it is feared that the resulting engine performance value will also not be good, if usually engine performance testing is limited to fuel variations such as the effect of modifying the timing of natural gas injection on engine performance [12], a combination of biodiesel from microalgal [13], variations of biodiesel fuel from animal oils [14], determination of engine performance values with biodiesel from palm oil mill effluent (POME) [8] and calculation of performance values using corn oil [7]. All of these research was carried out under normal engine conditions (not in tilted conditions) or in the sense that they were only to test engine performance, for offshore.…”

many industrial diesel engines are used as the main engine of the ship. Apart from being relatively cheaper, the availability of industrial engine is also very abundant, and the repair process is also not too complicated. However, when viewed from the SOLAS regulations related to the main requirements for a ship propulsion engine, it must also be considered, because it operates at sea, so that ship engines must be tougher than industrial engines, especially related to engine performance when experiencing rolling and trim. The purpose of this research is to test the feasibility of industrial diesel engines being operated on ships. By using a water-cooled single-cylinder diesel engine which is commonly used in small ships. The experimental method was used in this research to obtain optimal results according to the conditions in the field, the engine was made in three variations, namely the normal condition (without inclination angle), the rolling condition of 15 0 , and the trim condition of 5 0 which complies with SOLAS regulations related to the inclination angle. The results of the research obtained torque, Specific Fuel Consumption (SFC), and engine thermal efficiency in various engine variations. The highest torque is in the condition of the 15 0 rolling engine, which is 13.87 N.m. The lowest SFC is in the condition of the 15 0 rolling engine, which is 194 gr/kW.h. and the highest thermal efficiency was also obtained at the condition of the 15 0 rolling engine, namely 44.9%. The higher the engine speed, the higher the engine performance value in rolling 15 0 conditions, and the 5 0 trim conditions experience an increasing trend, but in low rotation conditions (750 Rpm) the performance decreases. Seeing the results obtained, a water-cooled single-cylinder diesel engine can be used as a small boat propulsion engine.

“…Rise in level of the sea, extinction of the species, risks in security of the food, threats to functionality of ecosystem and survival of biodiversity are few of several disadvantages linked to atmospheric rise in carbon (IV) oxide level (Lim et al, 2021). In the light of this, scientist all over the have expedite action towards search for reliable and sustainable new technology at mitigating carbon as well as alternative zero carbon source of energy to present fossil origin of energy (Azeez et al, 2021). Presently, technologies based on micro-algal strains have been established by scientists as having photosynthesis efficient and effective mechanism with capability of carbon (iv) oxide effective biological sequestration from a certain source into a considered potential biomass source of biofuels, which is a promising but now costly and expensive replacement to fuels from fossil sources (Mistry et al, 2019;Oliveira et al, 2021;Sydney et al, 2019).…”

Present dependence on fossil sources for meeting energy demand globally is unsustainable as a result of non‐renewable and depleting supplies. Therefore, this study focuses on production and characterization of biodiesel by Chlorococcum littorale (Chlorococcum sp.) isolated from fish pond in Owode fish farm, Nigeria. Biomass concentration, lipid extraction and quantification were determined by filtration, solvent extraction and gravimetric methods. Extracted lipid was transesterified to diesel through process catalyzed by concentrated tetraoxosulphate (VI) acid. The constituents of fats in biodiesel produced were examined through chromatography of gas and spectroscopy of mass. Model prediction was used to assess physical and chemical parameters of biodiesel. The data gathered was subjected to statistical analysis. Chlorococcum sp. had biomass concentration (4.42 ± 0.02 g/L), Lipid content (67.75% and biodiesel yield (96.33%). Biodiesel had 48.3%, 29.20%, and 22.50% fatty acids that are saturated, monounsaturated and polyunsaturated, respectively. The biodiesel produced has the kinematic viscosity (2.74 mm2/s at 40°C); point of flash (245°C); point of cloud (7°C); point of pour (−2°C) and density (0.8760 g/cm3). Furthermore, the acidity level (0.44 mgKOH/g), value of saponification (186.49 mgKOH/g), value of peroxide (3.25 meq/kg), iodine content (38.27 mgI2/g) as well as the free fatty acid (1.34%), number of cetane (65.78), oxidative resistance (7.33 h), saturated factor of long chain (28.16°C), plugging point of cold filter (35.62°C) and high heating value (43.24°C) fell within required standard by international body. Thus, Chlorococcum sp. is ideal microalgae isolate for the biodiesel production. The biodiesel produced conform satisfactorily with the acceptable global standard.
