Abstract

Transportasi berkelanjutan dan ramah lingkungan menjadi perhatian utama dalam upaya mengurangi dampak lingkungan dan ketergantungan pada bahan bakar fosil. Pada kegiatan ini desain baru becak listrik pengangkut sampah  menggunakan sumber energi terbarukan untuk mengatasi tantangan transportasi dan pengelolaan sampah. becak ini akan diimplementasikan di daerah Aceh dan sekitarnya, terutama di sekitar kampus Universitas Syiah Kuala, Banda Aceh. Desain inovatif ini menggabungkan karakteristik tradisional becak dengan teknologi energi terbarukan guna menciptakan solusi yang relevan dengan lingkungan setempat. Dalam desain becak listrik baru ini, baterai lithium-ion diintegrasikan sebagai sumber utama, dengan kemampuan pengisian ulang melalui baterai yang dipasang pada struktur becak. Ini menghasilkan manfaat ganda dengan operasional yang lebih ekonomis dan berkontribusi pada lingkungan yang lebih bersih. Implementasi becak listrik ini akan memberikan dampak positif terhadap transportasi sampah di perkotaan Aceh. Selain mengurangi polusi udara dan kebisingan, becak ini akan memfasilitasi akses ke lokasi yang sulit dijangkau oleh kendaraan konvensional. Penting untuk dicatat bahwa kegiatan ini merupakan bagian dari upaya pengabdian kepada masyarakat yang dilakukan oleh Universitas Syiah Kuala. Selain memberikan solusi bagi transportasi dan pengelolaan sampah, desain becak listrik ini dapat menjadi model untuk pengembangan kendaraan listrik lainnya yang menggunakan energi terbarukan. Ini akan memberikan kontribusi penting dalam mengurangi dampak negatif perubahan iklim dan mengurangi ketergantungan pada sumber daya fosil di daerah tersebut.

Abstract

The strength of fiber-reinforced composites is greatly influenced by the bonding at the fiber-matrix interface. Experimental methods to study this interface are often challenging, making numerical approaches essential for evaluating the interfacial behavior in fiber-reinforced composites. This study investigates the stress and strain distribution in the fiber, matrix, and fibermatrix interface regions of natural fiber-reinforced single-fiber composites under tensile loading using the finite element method. Interface conditions were modeled using cohesive elements, with the composites represented in two dimensions through ABAQUS 6.14 software. The tie constrains contact model was employed to define binding interactions between the cohesive element, the fiber, and the matrix. The maximum stress value resulting from the simulation process is 202 MPa and a strain of 0.0449 mm. The stress is effectively distributed to the fiber, demonstrating that the cohesive element used in composite analysis under tensile loading serves as a reliable link between the fiber and the matrix. The simulation results revealed a maximum stress value of 202 MPa and a corresponding strain of 0.0449 mm. The stress distribution effectively transferred to the fiber, demonstrating the capability of cohesive elements to represent the interfacial bond in composites under tensile loading. These findings confirm that cohesive element modeling is reliable method for analyzing fibermatrix interactions in natural fiber reinforced composites, providing insights for optimizing composite performance.

Abstract

The use of synthetic inhibitors that negatively affect the environment is still used. Organic inhibitors are the best and most environmentally friendly solutions such as Temiki plants (MelastomaCandidum) and Rubik (Calotropis Giganteen) which have good corrosion cell inhibitor properties and have the potential to be used as corrosion inhibitors. This study analyzed Temiki and Rubik extracts as corrosion inhibitors in carbon steel using the weight loss method in 3.5% NaCl solution and analyzed the efficiency of the inhibitors. Temiki and Rubik's are extracted by drying the leaves, stems and flowers under the sun. Then the material is mashed together and distilled by the solid-liquid method with the Soxhlet tool. Identification of plant components using Gas Chromatography-Mass Spectrometry (GC-MS). Density and viscosity were analyzed following ASTM D 4052 and ASTM D 445 standards. Weight loss method testing was carried out at inhibitor concentrations of 200, 300, 400 and 500 ppm, with soaking time for 15 weeks and data collection was carried out every week. The results of the analysis showed the highest corrosion rate in Temiki extract with a concentration of 500 ppm reaching 1,569 mpy and the lowest at a concentration of 500 ppm reaching 0.157 mpy. In Rubik's extract inhibitors, the highest corrosion rate occurred in 500 ppm inhibitors reaching 1,268 mpy, while the lowest occurred at 200 ppm concentrations reaching 0.331 mpy. The highest efficiency value is the 400 ppm Temiki inhibitor with efficiency reaching 82.89% and the lowest at 500 ppm reaching 19.55%. while for the efficiency of Rubik's extract inhibitors, the highest value was 62.71%, at a concentration of 200 ppm. While the lowest is 28.40%, at 500 ppm inhibitors. These results show that Temiki and Rubik's extracts can still function well as corrosion inhibitors in low-carbon steels in NaCl solution.

Abstract

The purpose of this study is to simulate drop-weight impact tests on hybrid fibre composites made of ramie and Eglass, which are used to make the traditional Acehnese boat wall material for jaloe kayoh. Using composites of ramie-Eglass fiber hybrid in the construction of jaloe kayoh wall material will significantly enhance the strength, durability, and sustainability of traditional Acehnese boats. The simulation was carried out using the finite element method approach using the Abaqus software. Three distinct laminate layer configurations—three layers (GRG), five layers (GRGRG), and six layers (GRGGRG)—with alternating Eglass and ramie fibres make up the test specimens. The ends of the specimen are set with fixed support to ensure boundary conditions, which limit all active structural degrees of freedom on all sides of the specimen. According to simulation results, the specimen with six laminate layers, measuring 12.498 mm, had the largest displacement. The specimen with six laminate layers has the highest stress concentration, measured at 560.6 MPa, while the specimen with three layers has the highest strain concentration, measured at 0.023. Its indicating that the lamina variation can influence the structural performance of the jaloe kayoh material. This research contributes to understanding the potential of ramie-Eglass hybrid fiber composites to enhance the safety and durability of traditional vessels such as jaloe kayoh. The implications of the results can serve as a foundation for the development of superior structural materials in the future.
