“…When redesigning, several main factors must be considered, such as the value of resistance and ship stability after changing the design must be better than the previous design [1]. With a high resistance value, it will affect the amount of engine power used [2]- [4] , besides that it will also greatly affect the value of fuel consumption because the amount of power is directly proportional to the rate of fuel consumption [5]. Several cases of ship redesign or commonly called ship conversion have also been carried out in related research studies.…”

In this research, the ship power plan which is the result of a conversion from a landing craft tank is designed to meet the electricity needs in areas affected by a disaster or electricity crisis. So far, the government has chartered a similar ship from Turkey which is used to meet electricity needs in Indonesian areas which have been affected by the disaster and electricity crisis. This ship is modified to carry an electric generator which can later be sent to areas that need it. Two main focuses are the goal of this research, the first is to find the value of the freeboard and the second is the trim of the ship after the redesign. To achieve this goal, in this study a numerical calculation method was used to calculate the freeboard and trim values according to applicable standards. The results of the analysis show that the freeboard value is still safe, with the actual freeboard value being greater than the required freeboard (0.8 m > 0.44 m). For ship trim, the bow trim condition is obtained with a smaller LCG-LCB difference than the 0.05% LPP value (0.912 < 0.923). By looking at the results of these measurements, the condition of the ship's freeboard and trim is still in a fairly good category even though it has been converted from a landing craft tank to a ship power plant. This study can provide a reference for ship design before converting the actual ship so that it can carry out trim and freeboard tests to prevent build failures.

“…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.

“…Biodiesel is produced through a transesterification reaction between triglycerides contained in fats or oils and alcohol. Oil as biodiesel feedstock with an FFA content of more than 5% will react with base catalysts in the transesterification reaction, causing a saponification reaction, so it is necessary to carry out an esterification reaction to reduce the FFA content of the raw material [2], [3]. Thus, an esterification reaction is necessary to reduce the FFA content below 5%w/w as a pretreatment step of the transesterification process.…”

The effect of sulfonic agents on the performance of solid acid catalysts in esterification reactions of long-chain fatty acids has been studied. Herein, sulfonated activated carbon with sulfanilic acid (SAC-SA) and sulfuric acid (SAC-SO4) as a sulfonic agent were prepared and used for esterification reaction to convert long-chain fatty acids into methyl esters within 5 h at 65°C. The obtained SAC-SA has a higher surface area than SAC-SO4 of 1301.981 and 1182.096 m2/g, respectively. When SAC-SO4 and SAC-SA catalysts were applied to the esterification reaction, the FAME product conversion results were 74.47 and 46.98 %, respectively. The physical property of SAC-SO4 has more macropores size distribution than mesopores size based on the BJH method. Large pore size on the catalyst will support the diffusion of large organic molecules to improve catalytic ability. The pore size determines the performance of solid acid catalysts, especially in long-chain fatty acid reactants for biodiesel production.
