Abstract

Pemanfaatan serat alam sebagai penguat komposit ramah lingkungan terus meningkat, namun keterbatasan sifat fisik, kimia, dan ikatan antarmuka masih menjadi tantangan utama dalam aplikasinya. Salah satu pendekatan modifikasi serat yang potensial dan relatif sederhana adalah perlakuan pengasapan, yang mampu memodifikasi struktur kimia dan morfologi permukaan serat. Penelitian ini menganalisis pengaruh durasi pengasapan suhu rendah terhadap komposisi kimia, sifat fisik, morfologi permukaan, dan kekuatan tarik serat tunggal pelepah aren bagian bawah. Pengasapan dilakukan menggunakan kotak pengasapan dengan sumber asap dari pembakaran tempurung kelapa, pada suhu terkontrol 45 °C, dengan variasi durasi 0, 5, 10, 15, dan 20 jam. Parameter yang diuji meliputi komposisi kimia, kekuatan tarik serat tunggal, serta karakterisasi permukaan menggunakan SEM. Hasil menunjukkan hemiselulosa menurun dari 23,70% menjadi 19,70% dan lignin dari 17,17% menjadi 10,34%. Kekuatan tarik meningkat dari 210,64 MPa menjadi maksimum 421,59 MPa pada durasi 15 jam, kemudian menurun pada 20 jam. Citra SEM mengonfirmasi peningkatan kekasaran permukaan hingga durasi optimum 15 jam, sedangkan pengasapan 20 jam menunjukkan indikasi microcrack dan delaminasi. Durasi pengasapan 15 jam direkomendasikan sebagai kondisi optimum.

Abstract

Leveraging maritime transport for bulk material shipments is a common approach in supply chain cost optimization efforts. However, the operational aspects of this shipping method are characterized by limited visibility and high levels of uncertainty. This condition is negatively correlated with the company's ability to meet established service level standards, ultimately leading to a decline in consumer trust. This research develops a simulation model to evaluate three scenarios aimed at improving service level. The three factors evaluated are optimization of port operating hours, implementation of a reorder point system, and increasing ship capacity. By implementing a combination of these strategies, the existing distribution system can be significantly improved. The results of this study indicate that implementing a combination of these scenarios can substantially improve the performance of the existing system. The most influential factor is the implementation of a reorder point (Factor 2), which results in an increase of 13.80%. The factor combination that yields the highest service level is scenario number 10, which achieves a service level of 92.36%.

Abstract

Natural fiber composites have the potential to serve as environmentally friendly materials; however, the quality of fiber–matrix interfacial bonding is strongly influenced by the initial treatment of the fibers. This study aimed to analyze the effect of alkali immersion time on the flexural deflection of epoxy-matrix palm fiber composites. Palm fibers were soaked in a 5% NaOH solution for varying durations of 0, 1, 3, 5, and 7 hours. The composites were fabricated with a volume fraction of 70% epoxy and 30% palm fiber and were tested for flexural deflection in accordance with ASTM D790 under a constant load of 6 kg (≈58.86 N). Each variation was tested using three replicate specimens. The results showed that flexural deflection decreased as immersion time increased, reaching a minimum at 5 hours, and then increased again at 7 hours. The highest average deflection was observed in composites without alkali treatment (5.20 mm), while the lowest deflection (4.23 mm) occurred at 5 hours of immersion, indicating improved flexural rigidity. Statistical analysis showed a coefficient of variation below 6%, indicating good data consistency. This behavior is associated with the reduction of lignin and hemicellulose content and improved fiber–matrix interfacial bonding. Overall, an alkali immersion time of 5 hours was identified as the optimal condition for improving the flexural deflection performance of palm fiber–epoxy composites.

Abstract

Menulis tesis dan publikasi ilmiah merupakan persyaratan kelulusan dan pengembangan akademik bagi mahasiswa, namun banyak yang menghadapi kesulitan dalam menghasilkan sitasi yang akurat, sehingga meningkatkan risiko plagiarisme. Artikel ini mengusulkan strategi menggunakan pendekatan dua alat dengan Mendeley dan Zotero untuk meningkatkan akurasi sitasi dan mengurangi plagiarisme dalam penulisan ilmiah. Kegiatan pengabdian masyarakat ini dilakukan melalui pelatihan di Laboratorium Komputer Teknik Universitas Kristen Indonesia Toraja pada tanggal 23 Mei 2025, dengan diikuti oleh 60 mahasiswa teknik mesin semester enam. Pelatihan berbasis lokakarya ini meliputi tahapan sosialisasi, instalasi aplikasi, praktik integrasi dua alat, simulasi sitasi otomatis, dan evaluasi keterampilan melalui pre-test dan post-test. Hasilnya menunjukkan peningkatan yang signifikan dalam penguasaan aplikasi dan akurasi sitasi, dengan keluaran berupa modul pelatihan, templat dokumen, dan layanan bimbingan referensi. Faktor pendukung seperti fasilitas, instruktur, dan antusiasme mahasiswa, serta hambatan seperti keterbatasan waktu dan tingkat keterampilan awal, dievaluasi. Kegiatan ini berkontribusi untuk memperkuat etika akademik dan efisiensi penulisan sekaligus mendorong adopsi berkelanjutan teknologi referensi digital.

Abstract

The performance of biomass stoves is influenced by fuel characteristics and operating conditions, including wood species and fuel mass. This study investigated the effects of wood species and initial fuel mass on the fuel consumption rate, thermal power, and thermal efficiency of a steam-injection biomass stove. Three wood fuels pine, fir, and coffee wood were tested at initial masses of 0.8, 1.0, and 1.2 kg, resulting in nine experimental conditions. The steam injector was supplied with 750 mL of water in each test. Stove performance was evaluated using the Water Boiling Test with 3 L of water at an initial temperature of 25°C. Fuel consumption, boiling duration, temperature, remaining fuel, charcoal, and water mass were recorded to calculate the fuel consumption rate, thermal power, and thermal efficiency. The results showed that increasing the initial fuel mass was accompanied by increases in fuel consumption rate and thermal power but decreases in thermal efficiency for all tested wood species. The highest fuel consumption rate and thermal power were observed with 1.2 kg of pine wood, reaching 0.0013 kg/s and 9.07647 kcal/s, respectively; however, its thermal efficiency was approximately 13%. In contrast, the highest thermal efficiency of 20% was obtained using 0.8 kg of fir wood. These findings demonstrate a trade-off between maximum heat output and efficient fuel-energy utilization. Under the tested conditions, pine wood at 1.2 kg was more suitable when high thermal output was prioritized, whereas fir wood at 0.8 kg provided the most favorable thermal efficiency. Further replicated experiments and statistical analyses are required to confirm the effects of wood species, fuel mass, and their interaction.
