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.

Abstract

The tests revealed the exceptional combustion properties of a blended fuel consisting of castor oil and rhodium liquid (Rhl) as a highly effective homogeneous combustion catalyst. Our findings indicate that castor oil's unique molecular structure makes it an ideal fuel component, and the catalyst interacts with the fuel's triglycerides to enhance fuel properties and facilitate ignition.These findings support the pivotal role of the synthetic catalyst Rhl, which effectively reduces the binding forces within the triglyceride chain through polarization interactions. As a result, molecular bonds become more flexible, providing electrons with greater freedom of movement. Synthetic catalysts induce significant modifications in the triglyceride structure, increasing electron energy levels and enhancing the reactivity of fuel molecules, ultimately leading to improved fuel combustion efficiency. Integrating the Rhl synthetic catalyst also enhances fuel performance by reducing ignition duration and increasing the combustion rate. The elevated combustion temperatures of the fuel droplets highlight the effectiveness of promoting environmentally sustainable combustion processes.

Abstract

The production of syngas from coffee husk biomass waste as a raw material offers significant potential as an alternative automotive fuel source through the gasification process, considering the abundant resources available. Therefore, this study aimed to characterize the physical properties of the fuel initially, in order to observe the differences in these properties after the fuel underwent Ultra Fine Bubble treatment. The objective was to analyze the combustion characteristics of syngas derived from coffee husk biomass waste, to develop a sustainable alternative to fossil fuels for automotive applications. The results showed that with increasing air discharge, the concentration of CO and Hâ‚‚ gases in gasified syngas increased while the concentration of CH4 decreased. Additionally, higher air discharge resulted in lower tar content, higher flame temperature, higher flame height visualization, and higher generator power output as a review of the feasibility of alternative automotive fuels.

Abstract

Corncob waste in Naramben Village is traditionally underutilized and frequently subjected to open burning, leading to air pollution and localized environmental degradation. This program introduces simple pyrolysis technology to equip local residents with the practical skills needed to transform this agricultural waste into value-added commodities: liquid smoke and biochar. Executed through a participatory framework, the initiative combined strategic preparation, hands-on production workshops, and educational dissemination. The program drove a substantial shift in community renewable energy literacy, with participants successfully adopting liquid smoke as an organic pesticide and natural fish preservative. From a technical standpoint, utilizing a 50-liter drum-type pyrolyzer over a two-hour cycle consistently yielded 1.5 to 2 liters of liquid smoke and 5 kg of biochar per batch. Evaluations confirmed that the direct demonstration approach effectively fostered operational independence among the villagers. Ultimately, this localized waste-to-energy model mitigates open-burning pollution, unlocks new micro-economic avenues, and advances clean energy resilience.
