Abstract

Research on themanufacture of composites reinforced with banana stem fiber and palm kernel shells aims to analyze the effect of variation in the volume fractionof banana stem fiber and palm kernel shells on the mechanical and physical properties of the composite. The composite was fabricated using the hand lay-up method with volume fraction variations (matrix: fiber: shell) of 40%:50%:10%, 40%:40%:20%, 40%:30%:30%, 40%:20%:40%, and 40%:10%:50%. Mechanical test include Charpy impact test, compressive strength test using a Universal Testing Machine (UTM),Vickers hardness test, and water absorption test. The results showed that the highest impact strength of 0,0947 J/mm2 was obtained at 40%:20%:40% composition, the highest compressive strength of 7,69 MPa at 40%:50%:10%, and the highest hardness value of 18,68 HV at 40%:40%:20%. The lowest water absorption value of 14,28% at 40%:10%:50%. These result indicate that the composition of 40%:20%:40% is the optimum composition for automotive dashboard applications, as it meets the mechanical standards required for dashboard materials.

Abstract

Advances in nanotechnology are driving the development of multifunctional materials, one of which is magnetic-luminescent nanocomposites that combine magnetic and fluorescent properties in a single system. These materials hold great potential for biomedical applications, particularly in bioimaging. Fe₃O₄ nanoparticles are widely used as magnetic materials due to their biocompatibility and low toxicity, while Carbon Quantum Dots (CQDs) are used as luminescent materials because they exhibit strong fluorescence, high photostability, and are non-toxic. However, Fe3O4/CQD nanocomposites suffer from particle agglomeration and quenching effects. To address these issues, encapsulation was performed using Zeolitic Imidazolate Framework-8 (ZIF-8), which possesses biocompatible, biodegradable properties, and high surface area and porosity. In this study, Fe₃O₄/CQD@ZIF-8 nanocomposites were synthesized. Coating with ZIF-8 is expected to act as a protective layer that has the potential to reduce agglomeration and minimize the quenching effect. The crystalline structure and functional groups of the material were characterized using X-ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR), while its optical properties were analyzed using fluorescence spectroscopy.
