Abstract

Fasilitas infrastruktur serta lingkungan sekitar berpotensi mengalami kerusakan lebih cepat akibat korosi. Jika korosi tidak segera ditangani, hal ini dapat menimbulkan kerugian yang cukup besar. Salah satu metode pencegahan korosi adalah proteksi katodik dengan anoda korban. Namun, karena biaya perawatan yang tinggi, teknik ini lebih sesuai digunakan dalam skala industri. Selain metode anoda korban, penggunaan inhibitor juga dapat menjadi solusi untuk mengendalikan korosi. Inhibitor adalah zat yang mampu memperlambat laju korosi meskipun diberikan hanya dalam jumlah kecil pada konsentrasi tertentu. Untuk menekan biaya perlindungan, beberapa inhibitor alami dapat dimanfaatkan dari bahan-bahan yang tersedia di sekitar, salah satunya adalah daun pepaya yang memiliki kandungan organik berpotensi menghambat proses korosi. Tujuan umum kegiatan pengabdian ini adalah memberikan edukasi kepada masyarakat mengenai pemanfaatan ekstrak daun pepaya sebagai penghambat korosi, khususnya untuk menjawab kebutuhan kelompok tani Limpah Ruah di Gampong Mekar Jaya, yang menghadapi permasalahan besi konstruksi pertanian seperti pagar yang cepat berkarat. Adapun tujuan khususnya adalah memberikan informasi mengenai cara pembuatan ekstrak daun pepaya sebagai inhibitor. Kegiatan yang dilakukan meliputi survei, pembuatan dan pengujian larutan inhibitor, serta penyuluhan kepada kelompok tani Limpah Ruah. Proyek pengabdian masyarakat ini merupakan kegiatan perdana yang dilaksanakan di wilayah Gampong Mekar Jaya.

Abstract

Efforts to manage waste are being carried out at various levels, ranging from households to large-scale industries that generate waste on a daily basis. The imbalance between waste generation and proper management has turned waste into a serious environmental concern. Among the different types of waste, plastic is one of the most difficult to naturally decompose (non-biodegradable) and represents the largest portion compared to other waste materials. Statistical data show that in several cities across Indonesia, the amount of non-biodegradable waste disposed of at final disposal sites reaches 6,598.23 tons per day. This study was conducted with both general and specific objectives. The general aim was to utilize plastic waste as a composite material, while the specific objective was to analyze the tensile strength properties of composites produced from plastic waste reinforced with durian fibers. By exploring the potential of plastic waste in construction materials, this research seeks to provide a sustainable solution to the plastic waste problem while contributing to environmental preservation. Four different specimens were prepared for testing: Specimen A (80% plastic waste and 20% durian fiber), Specimen B (60% plastic waste and 40% durian fiber), Specimen C (40% plastic waste and 60% durian fiber), and Specimen D (20% plastic waste and 80% durian fiber). The results revealed that Specimen B exhibited the highest average tensile strength of 20.9 MPa, indicating significant potential for enhancing material performance. In contrast, Specimen D showed the lowest average tensile strength of only 1.2 MPa, highlighting the need for further composition optimization to improve mechanical properties. Overall, this study provides valuable insights into the development of recycled composite materials for use in construction and broader industrial applications.

Abstract

Control systems education often faces a dichotomy between costly physical laboratories and accessible but numerically inaccurate simulation platforms, such as web-based simulators. Existing web-solutions typically rely on low-order integration methods, failing to capture realistic non-linear behaviors crucial for industrial applications. This study addresses these limitations by developing a high-fidelity, client-side Virtual Laboratory for DC Motor control. The novelty of this work lies in the integration of the Runge-Kutta 4th Order (RK4) algorithm within a lightweight HTML5/JavaScript architecture, eliminating server-side latency while ensuring superior numerical precision over standard Euler-based applets. Furthermore, the system implements a realistic discrete PID controller with a Conditional Integration (Clamping) Anti-Windup strategy, enabling precise analysis of actuator saturation effects. Validation benchmarks against standard numerical computing software like GNU Octave demonstrate rigorous accuracy. The proposed system achieves a steady-state relative error of less than 0.001% and shows negligible deviation in transient response metrics (rise time, settling time, and overshoot). Additionally, the virtual lab maintains identical closed-loop pole locations up to four decimal places. By integrating real-time Bode Plot and Root Locus analysis, this platform provides a robust, open-access tool that effectively bridges the gap between theoretical design and practical non-linear implementation challenges.

Abstract

The utilization of pineapple leaf fiber is still relatively small, only used as a basic material for various types of furniture products, fabrics for fashion products, crafts and composites as forming materials. This study aims to analyze the tensile strength of pineapple leaf fiber composites with variations in volume fractions using clear polyester resin. In this study, composites were made using three different volume fractions, namely 60% fiber: 40% resin, 70% fiber: 30% resin, and 85% fiber: 15% resin. After the test specimen manufacturing process, the specimens were then tested for tensile strength on each volume fraction. The results of this study indicate variations in tensile strength on each volume fraction used, where using a volume fraction of 85% fiber: 15% resin produces higher tensile strength compared to the volume fraction of 60% fiber: 40% resin and 70% fiber: 30% resin. Pineapple leaf fiber reinforced composites with variations in the volume fraction of pineapple leaf fiber 60%: resin 40%, pineapple leaf fiber 70%: resin 30%, and pineapple leaf fiber 85%: resin 15%. From the percentage variations, the highest tensile strength is in pineapple leaf fiber 85%: resin 15% with an average value of 105.69 MPa, elastic modulus strength of 1571 MPa, and elongation of 6.74%. While the lowest tensile strength value is in pineapple leaf fiber 60%: resin 40%, with an average value of 74.30 MPa, elastic modulus strength of 1231 MPa, and elongation of 6.04%, it can be concluded that the higher the percentage of fiber, the higher the tensile strength value. Variations in the volume fraction of pineapple leaf fiber can affect the mechanical properties of clear polyester resin composites. The composite strength value often increases with the increase in the fiber volume fraction. However, a high fiber volume fraction does not always have a good effect on the strength of the composite. The strength of the composite is not only influenced by the number of fibers but is also influenced by the binding factor, namely the matrix.

Abstract

The structural performance of Unmanned Aerial Vehicle (UAV) wing spars demands a balance between high strength and adequate stiffness. This study investigates the optimal configuration of bamboo–carbon fiber hybrid composites and evaluates the suitability of different spar cross-section geometries through experimental flexural testing, Taguchi-based statistical optimization, and Finite Element Method (FEM) simulation. Nine composite variations were fabricated and tested in accordance with ASTM D7264, employing three control factors: volume fraction, fiber ratio, and stacking sequence. The experimental results indicated that variation V7 (60% total fiber volume, 40:60 bamboo–carbon ratio, CBC stacking sequence) demonstrates the highest mechanical performance, achieving a flexural strength of 288.5 MPa and a flexural modulus of 31.8 GPa, which was further supported by the highest Signal-to-Noise (S/N) ratios for both responses. The optimum material configuration was subsequently applied to FEM simulations of three spar cross-sectional geometries. The results revealed that the hollow circular profile exhibited a limited safety margin (SF = 1.09), whereas the W-shaped and hollow-square profiles achieved higher safety factors of 2.15 and 2.18, respectively. Among the evaluated designs, the hollow-square spar provides the most favorable structural response, characterized by lower maximum stress, reduced deflection, and the highest safety margin.
