Abstract

This study investigated the moldability and the mechanical properties of bio-composite with rice husk as natural reinforcement. Natural materials that are abundant in nature can be used as reinforcement for polymer materials. Natural materials as reinforcement in plastic materials were used to obtain alternative materials in an injection molding process. With rice husk, polypropylene, and MAPP, four compositions of bio-composite materials were made and used as raw material injection molding process. The moldability from this material was observed through visualization of the product. The mechanical properties of the materials were observed by the tensile strength and impact test on the injection molding product. The result showed that these materials could be injected to form ASTM D638-03 Type V tensile test and ASTM D256-04 impact test specimens. Visually, the more rice husk on the bio-composite material, the darker the product color. The differences in tensile strength values decreased along with increased rice husk content. All bio-composite materials had roughly the same tensile strength value and were lower than polypropylene, except RH-5%. The impact value of bio-composites was lower than polypropylene impact value and tended to decline along with the increase in the rice husk content. Scanning electron microscope (SEM) analyzes were done on the fracture side of the impact specimen. Microscale voids decreased and were rarely found by adding rice husk to the material bio-composite. On the other hand, rice husk breakage and pullout phenomenon on bio-composite material were found.

Abstract

In this article, we report and compare the synthesis method of the active cathode materials based on nickel‐cobalt‐manganese (NCM) for lithium-ion battery application. We evaluate the hydrothermal and solid-state reaction method in NCM-622 synthesis, the material characterizations, and the battery performance. Based on the analytical results using X-ray diffraction (XRD), particles synthesized using hydrothermal and solid-state methods exhibit a highly crystalline NCM phase. NCM particles synthesized using solid-state reaction exhibit high-rate performance up to 10 C. The electrochemical impedance spectroscopy analysis shows that the charge transfer resistance (Rct) of NCM synthesized by the solid-state reaction (SSR) method was 25.9% lower than hydrothermal. Meanwhile, the ionic diffusivity of the SSR sample was 38.5% higher than the hydrothermal sample. These two factors lead to better performance when tested in a lithium-ion battery.

Abstract

This study focuses on examining aluminum chloride hexahydrate (AlCl3·6H2O) as an electrolyte salt in an Aluminum Ion Battery. The goal is to assess the effectiveness of AlCl3·6H2O as an electrolyte in an Aluminum Ion Battery, evaluate the battery's performance, and examine the anode and cathode properties of an Aluminum Ion Battery. Laboratory tests and literature analysis are the approaches used. Following cyclic voltammetry testing, it was shown that the water-in-salt electrolyte AlCl3 performed better than the 1M AlCl3 electrolyte. Compared to the 1M AlCl3 electrolyte, the hydrogen evolution reaction in the water-in-salt electrolyte AlCl3 has a smaller potential range. The cyclic voltammetry graph of an aluminum ion battery containing a water-in-salt AlCl3 electrolyte is noticeably smaller than that of an aluminum ion battery with a 1M AlCl3 electrolyte. It has been observed that the water-in-salt AlCl3 electrolyte requires more activation energy compared to the 1M AlCl3 electrolyte. Based on SEM-EDS data, using water-in-salt electrolyte AlCl3 for aluminum ion batteries is better as it does not cause significant defects in the anode and cathode.

Abstract

This research is about solid polymer electrolyte (SPE) based on polyvinyl alcohol (PVA) synthesized using a solution casting technique by adding variations of sodium sulfite salt and glycerol as fillers to reduce the samples' bulk resistance for electrochemical energy storage application. The method used is a quantitative analysis based on the test results. X-ray Diffraction (XRD) was used to determine the crystallinity and structure of the solid polymer electrolyte material. Interactions between Na+ ions from salts in SPE were analyzed using Fourier transform infrared (FTIR). The mechanical properties of the SPE samples were analyzed using tensile testing (ultimate tensile strength). Solid polymer electrolyte (SPE) ion conductivity was analyzed using electrochemical impedance spectroscopy (EIS) with temperature variations of 25, 40, 50, 60, and 70°C. The maximum SPE ionic conductivity value is 1.05 × 10-5 S cm-1 in a PVA-Glycerol-Na2SO3 15% sample at 70°C.

Abstract

The car door is a vital component of an automobile, playing a key role in passenger safety during accidents. For an energy-saving competition, the strength of a car prototype's door was thoroughly examined using Finite Element Analysis (FEA). This study involved three testing methods: pole side impact, side impact, and door slam tests. Simulations were conducted using the Finite Element Method (FEM) with aluminum alloy 6061-T4, type-E fiberglass, and type-S fiberglass as materials. These materials were selected based on their stress properties, mass, and cost. The simulation indicated that the side impact test produced the highest stress levels, especially in the fiberglass materials. While the aluminum alloy exhibited higher von Mises stress than its tensile strength in one case, both types of fiberglass maintained safety as their tensile strengths exceeded the maximum von Mises stress. The pole side impact test showed aluminum's highest stress and deformation, whereas fiberglass materials showed higher stress and deformation in the side impact test. The door slam test demonstrated minimal stress and deformation across all materials. Among the three, type-E fiberglass demonstrated the most favorable and safest performance. Consequently, type-E fiberglass is highly recommended as the ideal material for the car prototype's door.

Abstract

Perkembangan teknologi robotika memberikan peluang besar untuk memperkaya proses pembelajaran di tingkat sekolah menengah, khususnya dalam penguatan keterampilan abad ke-21. Namun, minimnya akses terhadap pengalaman praktik membuat siswa kesulitan memahami konsep robotika secara aplikatif. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mengenalkan konsep dasar robotika industri kepada siswa SMAK Tunas Bangsa Gading Serpong melalui praktik langsung dalam merakit dan menguji robot pengikut garis (line follower). Metode pelaksanaan kegiatan dibagi menjadi tiga tahap, yaitu persiapan, pelaksanaan, dan evaluasi, yang secara implisit mengikuti tahapan dalam model pengembangan instruksional ADDIE (Analysis, Design, Development, Implementation, Evaluation). Peserta dibimbing dalam perakitan tiga jenis robot: Analog A, Analog B, dan Digital. Evaluasi dilakukan melalui survei pre-test dan post-test, pengujian performa robot, serta kuesioner kepuasan peserta. Hasil menunjukkan adanya peningkatan rata-rata pemahaman dari 68,15% menjadi 84%. Peningkatan paling signifikan terlihat pada aspek teknis seperti pengenalan sensor dan penggunaan perangkat lunak Arduino IDE. Dari segi performa, robot Analog A memiliki waktu tempuh tercepat (18,70 detik) dan konsumsi daya terendah (0,64%), sedangkan robot Digital lebih kompleks namun belum optimal dalam lintasan uji terbatas. Survei kepuasan menunjukkan 98% peserta merasa puas terhadap kegiatan. Kegiatan ini terbukti efektif dalam meningkatkan literasi teknologi dan memberikan pengalaman belajar berbasis praktik yang bermakna, serta relevan dalam mendukung implementasi SDGs poin 4 tentang pendidikan berkualitas.
