Abstract

Humans, by nature, are inclined to share knowledge across various platforms, such as educational institutions, media outlets, and specialized research publications like journals and conferences. The consistent oversight and evaluation of these publications by ranking bodies serve to maintain the integrity and quality of scholarly discourse on a global scale. However, there has been a decline in the proliferation of such publications in recent times, partly attributed to ethical misconduct within specific segments of the scholarly community. Despite implementing systems such as the Open Journal System (OJS), publishers grapple with the formidable task of managing editorial and review processes. Compounding the multifaceted nature of scholarly content, manual review procedures often lead to considerable time investment. Thus, a pressing need exists for advanced technological solutions to streamline the article selection process, empowering publishers to prioritize articles for review based on topical relevance. This study advocates adopting a comprehensive framework integrating advanced text analysis techniques such as keyword extraction, topic clustering, and summarization algorithms. These tools can be implemented and integrated by connecting with the database of the existing system. By leveraging these tools with the expertise of editorial and review teams, publishers can significantly expedite the initial assessment of submitted articles. Given the rapid technological advancements, publishers must embrace robust systems that enhance efficiency and effectiveness, particularly in reviewer assignments and article prioritization. This research employs the neural network approach of BERT and K-Means clustering to perform keyword extraction and topic clustering. Furthermore, using BERT facilitates accurate semantic understanding and context-aware representation of textual data. Additionally, BERT's pre-trained models enable its fine-tuning capability to allow customization to specific domains or tasks. By harnessing the power of BERT, publishers can gain deeper insights into the content of scholarly articles, leading to more informed decision-making and improved publication outcomes.

Abstract

The fluctuation of gold prices throughout the year makes it difficult for both investors and regular individuals to predict the future value. The goal of this research is to utilize various statistical techniques, such as linear regression, naive bayes, and various types of smoothing algorithms, to predict the price of gold. The data used in this study was obtained from Kaggle and is from a 70-year time period. The results showed that using a single exponential smoothing method had the highest accuracy and precision, with a good MAPE score of 7.12%. This study is unique in that it compares multiple algorithms using data over a long time period, and it can be useful for investors and traders in making decisions related to gold prices. Additionally, it can also serve as a reference for future research studies.

Abstract

Bantuan Hidup Dasar (BHD) merupakan keterampilan esensial yang harus dikuasai oleh setiap tenaga kesehatan, terutama dokter, untuk mengatasi situasi darurat seperti henti jantung dan kecelakaan lalu lintas. BHD berperan penting dalam memberikan oksigenasi darurat pada organ vital melalui ventilasi buatan dan sirkulasi buatan hingga fungsi paru dan jantung pulih. Efektivitas BHD sangat penting untuk mencegah kematian sel akibat kekurangan oksigen dengan melakukan resusitasi jantung paru (RJP) dan penggunaan Automated External Defibrillator (AED). Statistik menunjukkan bahwa henti jantung mendadak merupakan penyebab utama kematian di dunia, dengan prevalensi yang signifikan di Indonesia. Penyakit jantung koroner dan gagal jantung adalah penyakit jantung yang umum terjadi pada orang dewasa, dan prevalensi henti jantung lebih tinggi pada perempuan serta penduduk perkotaan. Kegiatan Pengabdian Kepada Masyarakat ini ditujukan untuk memberikan tambahan pengetahuan tentang apabila ditemukan seseorang mengalami henti nafas dan henti jantung, sehingga diharapkan masyarakat dapat menangani kejadian tersebut secepat mungkin atau segera merujuk ke pusat Kesehatan agar dapat menurunkan angka morbisitas dan mortalitas. Kegiatan dilakukan di AIS Al Jannah, Depok, tanggal 15 Mei 2024. Kegiatan pelatihan BHD di Sekolah IAS Al Jannah Depok, bekerja sama dengan Fakultas Kedokteran Trisakti, menunjukkan bahwa penyuluhan dan simulasi tindakan BHD dapat meningkatkan pengetahuan dan keterampilan peserta secara signifikan. Pelatihan ini memberikan manfaat besar dalam meningkatkan kepercayaan diri peserta dalam memberikan BHD dan kesiapan mereka untuk menerapkan keterampilan ini dalam situasi darurat.

Abstract

Background: The literature on early-onset colorectal cancer (EOCRC) reveals a complex interplay of symptoms, diagnostic challenges, and the need for increased awareness among both patients and healthcare providers. The systematic review by (Mitchell et al., 2007) underscores the necessity of recognizing red flag symptoms such as rectal bleeding and changes in bowel habits, as these are critical for timely diagnosis and intervention. The study highlights that delays in diagnosis can lead to more advanced disease stages, emphasizing the importance of patient education regarding the seriousness of these symptoms. Literature Review: Further investigations, such as those by (Renzi et al., 2016), reveal that many patients present with significant symptoms well before their diagnosis, indicating a gap in timely medical consultation. The findings suggest that abdominal pain and rectal bleeding are prevalent among emergency presentations, yet many patients do not receive timely evaluations, leading to missed opportunities for early intervention.The exploration of risk factors by (R Syed et al., 2019) highlights the challenges faced by younger patients, who often misinterpret their symptoms, resulting in substantial delays in seeking medical attention. This trend is echoed in the study from Indonesia by (Makmun et al., 2021), which notes that abdominal pain is the most common presenting symptom among early-onset CRC patients. The demographic characteristics presented in this study further emphasize the need for targeted screening and awareness initiatives.. Conclusion: In conclusion, the literature collectively emphasizes the critical need for heightened awareness and education regarding the red flag signs and symptoms of early-onset colorectal cancer. There is a clear call for improved diagnostic protocols and screening strategies to enhance early detection and treatment outcomes for this vulnerable population. Addressing both patient and healthcare provider awareness is essential to mitigate delays in diagnosis and improve prognosis for young patients with EOCRC

Abstract

Ensuring operational integrity across industries and protecting sensitive data require strong authentication systems. This paper presents a novel hybrid stateless authentication method that integrates binary payloads, token specifications, and database solutions. By employing a distinctive expiration policy, our proposed approach overcomes limitations inherent in traditional token revocation strategies while achieving token verification speeds that are up to 86 times faster than conventional statefull session-based methods. Overall, through uniformed benchmarking experiments and a comprehensive review of the literature substantiate the performance and security advantages of our method. Ultimately, this hybrid technique offers a more scalable and secure framework for authentication management, enabling efficient and flexible deployment in high-demand distributed environments.
