Abstract

The effective and efficient use of biomass briquettes is strongly influenced by the type of stove used and the way it is used. This study aims to design a briquette stove by adding an adjuster: the test fuel used honeycomb briquettes and forest fern charcoal. The heat transfer from burning honeycomb briquettes to a pot of water needs to be maintained so that the heat (temperature) remains constant during the combustion process. In the current use of briquettes, the distance between the briquette flame and the pot of water is unstable because the space is getting further away from the pool of cooking water. The combustion distance is getting farther because the bottom of the initial honeycomb briquettes burns out, causing the surface of the briquettes to decrease and move away from the surface of the water pot. Thus the heat given to the pool of water will reduce. The briquette stove needs to be added with an adjuster to overcome this problem. This adjuster serves to raise the honeycomb briquettes if the surface of the briquettes decreases. With the addition of an adjuster, it will be analyzed how much the heat transfer rate and the stability of the burning distance of the honeycomb briquettes will be. In this study, 2 test models will be used: a stove with an adjuster and a stove without an adjuster, using 14 holes in honeycomb briquettes made from forest ferns using starch (tapioca) adhesive. The distance between the surface of the briquettes and the pot of boiled water is 5 cm. The results showed that the briquette stove using an adjuster could maintain the stability of the combustion distance between the surface of the briquette and the pot of water being cooked with an average temperature t = 567.83 0C and conduction heat transfer q = 5285.699 Watt.

Abstract

Biofuel derived from raw vegetable oil is considered a crucial alternative energy source to address the escalating fuel energy crisis due to the growth of industrial activities and the human population. The compounds present in raw coconut oil, including saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, and glycerol, constitute the focus of this research. The combustion of raw coconut oil involves a complex reaction due to the presence of saturated chain bonds, necessitating additional substances to weaken the carbon chains and enhance the combustion rate. This study employs the suspended droplet combustion method to increase the contact between air and fuel, thereby improving the reactivity of fuel molecules. To boost the combustion rate of coconut oil droplets, a bio-additive in the form of clove oil is experimentally added. Research findings reveal that the compound eugenol in clove oil possesses aromatic properties and a non-symmetrical carbon chain geometry. This factor can potentially expedite effective collisions among fuel molecules, consequently improving the ease of fuel combustion. In conclusion, this research provides insights into the potential use of coconut oil as a biofuel, highlighting the role of bio-additives such as clove oil in enhancing combustion rate efficiency. The study contributes to our understanding of strategies that can be applied to optimize the utilization of biofuel derived from raw vegetable oil.

Abstract

The limited availability of diesel oil encourages efforts to find new energy sources as alternative diesel fuels. Biodiesel can be extracted from various agricultural products, for example, coconut oil. As a tropical country, Indonesia is a very effective and potential country as a coconut producer. Vegetable oil has a higher viscosity than diesel oil. Compose bio-oils with various fuels additive is the way to reduce viscosity values, among others, by combining nanocarbon and metal catalysts. This study goals to know the characteristics of burning coconut oil as an alternative fuel with the addition of eucalyptus oil; and how long the combustion process takes from the starting point to the end. The results showed that adding eucalyptus oil to coconut oil can reduce the weakening of the carbon chain and increase the combustion temperature. The combustion efficiency of this coconut oil mixture varies depending on the amount of eucalyptus oil added, resulting in faster fuel combustion and a more powerful explosion. The color of the fire is an essential factor in ensuring that this mixture can be used safely and efficiently.

Abstract

Activated carbon is a crucial material widely used in various applications, including water purification and waste treatment. Areca nut husk, often regarded as waste, shows great potential as an alternative raw material for activated carbon. This study aims to characterize the structure and chemical properties of activated carbon derived from areca husk waste through an ethanol activation process. The activation process was conducted to enhance the porosity and surface area of the activated carbon, thereby increasing its adsorption capacity. Microstructure observations, XRD, TGA, and FTIR analyses were conducted to evaluate the quality of the activated carbon. The results showed that activated carbon with activation has a more complex pore structure, higher crystallinity, and additional functional group such as hydroxyl, which improve adsorption capacity and thermal stability. This study demonstrates that ethanol-activated areca husk has significant potential for various environmental and industrial applications.

Abstract

This study aims to reveal the combustion characteristics of coconut oil as an alternative fuel by adding active bio-carbon catalysts from areca nut skin. 1-3 ppm catalysts reduce viscosity, so the fuel quickly absorbs heat and ignites. This study uses the www droplet ignition method to increase the contact area between air and fuel so that the reactivity of fuel molecules increases. The results showed that adding areca nut skin-activated carbon catalysts improved fuel performance, whereas coconut oil fuel can absorb heat and release energy quickly. This was clarified from the results of the TGA test, where when compared with a mixture of 1 to 3 ppm, it was seen that the mix of coconut oil with a two ppm catalyst was the most effective because it had a high temperature with a stable heat flow. These results indicate that activated carbon from areca nut skin has excellent potential to be used as a biocatalyst for environmentally friendly and economical vegetable oil.

Abstract

Biomass gasification is a promising renewable energy technology for the production of synthetic gas (syngas), consisting of hydrogen (H₂), carbon monoxide (CO), and methane (CH₄). This technology's primary challenge is tar formation – a heavy hydrocarbon compound that can block equipment, poison catalysts, and deteriorate syngas quality. Therefore, this study aimed to examine different tar reduction methods to support clean energy production through biomass gasification. To achieve this aim, two main approaches were adopted and the first was in-situ, focusing on modifying gasifier design and adjusting operational parameters. The second was ex-situ, which included catalytic reforming, thermal cracking, and plasma technology. The analysis also assessed different catalysts, such as biochar, and dolomite, as well as nickel- and iron-based materials, comparing their efficiency, sustainability, and economic viability. Several key factors influenced tar formation and reduction, namely feedstock type, operating temperature, air ratio, and reactor configuration. The result showed that combining in-situ and ex-situ technologies had substantial potential to significantly reduce tar, improve syngas quality, and optimize system performance. However, some challenges observed were reduced catalyst efficiency, high energy costs, and the need for more sustainable technologies. To improve the performance of gasification systems, this study provided information on catalyst development, operational parameter optimization, and plasma technology integration. Finally, the analysis provided a scientific basis and strategic recommendations to overcome tar problems and encourage the commercial use of biomass gasification towards a clean energy transition.
