The increasing prevalence of deep hoaxes, such as fake news and phishing schemes, poses a significant threat to cybersecurity, undermining trust and spreading misinformation. In Indonesia, surveys indicate that more than 60% of people exposed to hoax news believe that it is true, emphasizing the urgent need for robust detection methods. Traditional cybersecurity approaches often struggle to keep pace with the growing scale and sophistication of these attacks. To address this challenge, this research investigates the use of deep learning techniques, specifically focusing on text-based hoax detection in the Indonesian language. The study fine-tunes IndoBERT, a pretrained deep learning model optimized for Indonesian text, to enhance the accuracy and scalability of hoax detection. The IndoBERT model was trained on a balanced dataset of 29,552 articles, comprising both hoax and real news content, collected from the Mafindo API and Kaggle's Indonesia News Dataset. The model was fine-tuned using supervised learning and evaluated using several key metrics, including accuracy, F1-score, precision, and recall. The results demonstrate that IndoBERT outperforms existing state-of-the-art approaches, achieving an accuracy of 98.51%, an F1-score of 98.44%, and a precision of 98.23% on the test set. These results highlight the effectiveness of IndoBERT for hoax detection, which offers a scalable solution to improve cybersecurity defenses against deceptive content. This research contributes to the integration of advanced deep learning models into cybersecurity systems, addressing the evolving landscape of cyber threats. © 2025 IEEE.

study of the effect of the bark on the compression strength of galam wood (Melaleuca Cajaputi)

引用

AIP Conference Proceedings 2024年第1期2927卷

作者： Muhammad Noor Asnan V. Vebrian Faculty of Science and Technology Civil Engineering Study Program Universitas Muhammadiyah Kalimantan Timur Indonesia

Melaleuca Cajaputi (Kayu Galam) is a type of tree that grows very fertile in swampy areas. This wood is commonly used in natural conditions (barked) in construction work. Meanwhile, other woods are generally used in a processed condition (without bark). For this reason, this paper compared galam wood with bark and without bark. This research was conducted by testing the physical characteristics and compressive strength in the laboratory. The compressive strength samples consisted of natural conditions (irregular round shape) with variations in length of 10 cm, 15 cm and 30 cm. Furthermore, each variation is made into a barked and peeled bark. All samples amounted to 126 units. The results of specific gravity and water content were not significantly different between barked and without bark. The water absorption in the shelled galam was 49.25% greater than that without the bark. Furthermore, the effect of the galam bark layer reduces the average strength by 24.92% and undergoes compression and shear failure. The failure of the test object with a ratio of length to diameter greater than 5 is indicated to have a buckling effect.

Alginate-based bioink for organoid 3D bioprinting: A review

引用

Bioprinting 2022年 28卷

作者： Leonardo, Michael Prajatelistia, Ekavianty Judawisastra, Hermawan Materials Engineering Study Program Faculty of Mechanical and Aerospace Engineering Institut Teknologi Bandung Indonesia Materials Science and Engineering Research Group Faculty of Mechanical and Aerospace Engineering Institut Teknologi Bandung Indonesia

As a 3D cell culture, organoids have been researched thoroughly to model the human biology system in advancing disease treatment and drug development. A novel way to create an organoid is using bioink, consisting of polymeric materials and living cells, to fabricate a hydrogel scaffold through the 3D bioprinting method. Alginate has the potential to be developed as a bioink due to its good biocompatibility, low toxicity, and ease of processing method. However, studies are still required to obtain an optimum alginate-based bioink. Alginate is insufficient in terms of the cell-binding site;thus, mixing it with supplementary gelatin material can be employed to optimize further the printability, mechanical properties, and biocompatibility of alginate-based bioink. The addition of gelatin material, in addition to increasing the binding site, also makes the process of making bioink easier due to the thermoresponsive nature of gelatin. The alginate-based bioink can be further optimized depending on gelatin concentration to produce appropriate density and rheological value of bioink. The addition of gelatin into alginate-based bioink will also significantly affect the printability of bioink and the mechanical properties of resulted hydrogel scaffold, which need to be considered appropriately. The alginate-based bioink also showed good biocompatibility regarding cell viability and biological performance. This paper focuses on the relationship between the structure and properties of alginate-based bioink, the 3D bioprinting processing parameters, and the implementation of resulted hydrogel scaffold and organoid. © 2022 Elsevier B.V.

We investigate thermomagnetic transport in an ultracold atomic system with two ferromagnets linked via a magnetic quantum point contact. Using the nonequilibrium Green’s function approach, we show a divergence in spin conductance and a slowing down of spin relaxation that manifest in the weak effective-Zeeman-field limit. These anomalous spin dynamics result from the magnonic critical point at which magnons become gapless due to spontaneous magnetization. Our findings unveil untapped dynamics in ultracold atomic systems, opening new avenues in thermomagnetism.
