Abstract

Continuous exploitation of fossil fuels causes scarcity, so appropriate solutions and policies are needed. One of these solutions is to utilize vegetable oil, and one of them comes from sunflower seed oil, which contains 17% oleic fatty acid and around 73% linoleic. However, its high viscosity, making it difficult to burn, hampers its use as an alternative fuel. Therefore, efforts are made to reduce its viscosity. One of these efforts is to add a catalyst in the form of active nano bio carbons derived from areca nut skin. Droplet combustion is chosen to increase the contact area between air and fuel so that the reactivity of fuel molecules increases. The study's results showed that the quality of fuel produced from a mixture of sunflower seed oil and active nano biocarbon from areca nut skin was improved. It was found that a concentration of 1 ppm was the best compared to other concentrations (2 and 3 ppm). It can be seen that it was able to reduce the viscosity of sunflower seed oil to 11.16 cSt, reduce the flash point at 138°C, and can increase the droplet combustion rate by around 2.05 seconds.

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

Advancements in science and technology are creating challenges for conventional materials such as metals, often struggle to meet the demands of modern industry. In response to the issue, train industry has begun developing applications of Glass Fiber Reinforced Polymer (GFRP) composite for interior panels. Therefore, this research aimed to determine the impact of fiber volume fraction and arrangement direction on tensile as well as bending tests. This research also aimed to identify variations in composite manufacturing process parameters to achieve optimal tensile and bending strength values. The research methodology was an experimental procedure with data analysis using Statistics Software. During the analysis, the results showed that the fiber volume fraction of 30% with the fiber arrangement direction of 0° produced optimal tensile and bending strength values. Tensile and bending tests produced results of 100.82 kg/mm2 and 102.27 kg/mm2, respectively. A high fiber volume fraction led to optimal tensile and bending strength values because the fiber served as the main reinforcement. Additionally, direction of the fiber arrangement played a significant role, with 0° fiber orientation producing better results due to a more even fiber distribution compared to 90° direction. The results of this research could be applied to the wall panels in the railway industry.

Abstract

Agricultural intensification in Indonesia increasingly relies on fossil energy inputs while leaving substantial agricultural residues underutilized. In Papua’s Keerom lowlands (<100 m altitude), maize expansion has created opportunities for integrating sustainable irrigation management with biomass-based energy systems. This study proposes a dual-pillar agro-energy framework combining irrigation efficiency analysis with pyrolysis–fermentation pathways for valorizing corn residues, particularly cobs and husks. Field survey data from 45 respondents were used to estimate energy inputs in maize cultivation, while pilot-scale pyrolysis experiments (450–550 °C) were conducted to evaluate biochar and bioenergy co-product generation. Results show that total energy input for corn production in Keerom averages 3,950 MJ ha⁻¹, substantially lower than values reported for mechanized highland systems. Slow pyrolysis produced approximately 27% biochar, 38% bio-oil, and 35% syngas, with biochar exhibiting a calorific value of 25.5 MJ kg⁻¹. Ethanol production through dilute acid hydrolysis and simultaneous saccharification fermentation yielded 28.3 L per 100 kg corn feedstock. The integrated system demonstrates potential for improving energy efficiency and reducing agricultural waste while generating decentralized renewable energy. These findings highlight the feasibility of circular agro-energy systems in tropical lowland environments and provide insights for sustainable biofuel development in eastern Indonesia.

Abstract

Alternative fuels were developed by blending crude coconut oil and bio-carbon nanoparticles. Bio-carbon, derived from sago waste via pyrolysis and ground using a ball mill, underwent FTIR testing to assess its energy absorption capabilities. SEM analysis was conducted to examine the surface morphology of bio-catalyst with and without crude coconut oil. The findings indicate that incorporating bio-catalyst can enhance mechanical properties, facilitating rapid heat absorption, as evidenced by reduced flashpoint and viscosity. In addition, the results show an increase in fuel mass, broadening of molecular contacts, increased reactivity, and increased heat absorption for easier ignition. This phenomenon indicates that bio-carbon of sago waste have great potential for biofuel use as a homogeneous combustion catalyst.

Abstract

The research aims to analyze and reveal combustion characteristics in a Cylindrical Meso Scale (CMS) Combustor with a wire mesh flame holder as a reference for designing a compact, efficient, and high-density energy source for future vehicles. This experiment analyzes the combustion ’s of a butane gas (C4H10)-air mixture in a cylindrical meso-scale (CMS) combustor with the addition of wire mesh flame holder on the stability of the combustion flame, as initiation of future vehicle energy source. The diameter of the CMS combustor with wire mesh flame holder is varied to give an idea of the effect of heat loss on the combustion flame's characteristics. The results show that the wire mesh as a flame holder is essential in the combustion stabilization mechanism. A stable flame can be stabilized in a CMS combustor with wire mesh. Variations in the diameter of the CMS combustor will result in variations in the surface-to-volume ratio, heat loss, and contact area of the wire mesh flame holder. At a large diameter, it produces the characteristics of a combustion flame with a more stable flame stability limit than a smaller diameter, a dimmer flame visualization than a smaller diameter at the same air and fuel discharge, a more distributed flame mode map area than the smaller diameter, lower flame temperature and combustor wall temperature than the smaller diameter, and relatively higher energy output than the smaller diameter.
