Abstract

Composite is a combination of materials formed from mixing between two or more of the forming materials. This research aims to determine the effect of variations in fiber length with lengths of 4cm, 6cm, and 8cm with a volume fraction of OPEFB fiber of 30% and NaOH alkaline immersion for 2 hours. The tests carried out were tensile testing using ASTM D3039 and bending testing using ASTM D7264. Based on the study's results with the 30% OPEFB fraction with the highest tensile strength yield, the 8cm fiber length of 13,33 MPa was achieved. Meanwhile, the lowest value was achieved with a length of 4cm of 3,2MPa.

Abstract

In this modern era, the palm oil industry is growing, so the waste is also increasing. If the waste from the palm oil industry is not processed, it will pollute the environment. One way to process palm oil waste is to turn the empty palm fruit bunches (OPEFB) fibers into composite reinforcement. Various natural fibers can be applied to become composite reinforcement, so it is necessary to study the character of OPEFB fibers for composite reinforcement. This study will look at the effect of various volume fractions on the bending strength of the composite. The volume fraction consists of 20%, 30%, and 40% fiber. The composite is then tested for bending to determine the bending strength of the composite. The results of the tests showed that the highest bending strength value was the 30% volume fractional variation with 47.70 MPa. The 40% volume fraction variation has the lowest bending strength value of 29.53 MPa.

Abstract

The wede168 growing demand for sustainable propulsion in heavy-duty transport has intensified research on Gasoline Compression Ignition (GCI) engines integrated with hybrid powertrains. This review presents a comprehensive comparative evaluation of series–parallel hybrid architectures for GCI-powered heavy-duty vehicles, emphasizing energy efficiency, combustion stability, and emission performance. This study systematically analyzed publications from the SAE, IEEE, Elsevier, and Springer databases, published between 2015 and 2025, through a rigorous peer-reviewed selection framework. The results show that series–parallel configurations provide better power distribution between the GCI engine and the electric motor, achieving 8–15% higher fuel-to-wheel efficiency than conventional diesel hybrids. Thermal–energy coupling models improve heat management and combustion consistency, reducing NOx and particulate emissions by up to 45%. Additionally, the use of deep reinforcement learning (DRL) and model predictive control (MPC) enhances adaptive energy management under varying load conditions. However, challenges remain in maintaining combustion stability during transient operations and optimizing hybrid mode transitions. Overall, this review identifies the series–parallel GCI hybrid architecture as a promising intermediate technology bridging conventional diesel systems and future zero-emission solutions, particularly for long-haul and urban heavy-duty applications.
