Abstract

Artificial intelligence (AI) has emerged as a tool with great potential to change the way we teach and learn, especially in the context of language learning. This article discusses the various benefits and challenges associated with integrating AI into education. By leveraging AI technology, teachers can create more personalized and adaptive learning experiences, uniquely tailored to each student's needs and abilities. In addition, AI can enhance the effectiveness of learning by providing real-time feedback and automated assessments, helping students develop their speaking and writing skills. However, challenges such as data privacy and the need for clear policies must be addressed to ensure the effective and ethical application of AI-based tools. More systematic research and assessment is needed to understand the impact of AI on student learning outcomes and to build trust between teachers and other stakeholders.

Abstract

This study aims to analyze the Springate method in predicting financial distress in Tourism, Restaurant, and Hotel companies listed on the Indonesia Stock Exchange during the 2019-2024 period. The method used in this research is Springate's financial ratios, with data processed using Microsoft Excel. This research is a descriptive quantitative study. The population for this study consisted of 43 companies. The sampling technique used was purposive sampling, resulting in a sample size of 20 companies. The data source was secondary data in the form of annual financial reports from the selected companies for the 2019-2024 period. Based on the S-Score analysis of the sample companies, a significant trend of financial distress was found. In 2019, 14 out of 20 companies experienced financial distress. This situation worsened drastically in 2020, where all sample companies were identified as financially distressed, indicating the major impact of the COVID-19 pandemic and the continuing challenging conditions in 2021. Although there was an improvement post-pandemic, with 4 companies not experiencing financial distress in 2022 and 6 companies not experiencing financial distress in 2023, the financial condition of this sector remains unstable. Fluctuations in 2024, with only 5 companies not experiencing financial distress, indicate that the financial stability of this sector has not fully recovered and remains vulnerable to various factors.

Abstract

High Multispectral imaging has become a promising approach in liquid classification, particularly in distinguishing visually similar but subtly spectrally distinct solutions, such as pure water (H₂O) and water mixed with sodium hydroxide (H₂O with NaOH). This study proposed a classification system based on image segmentation and deep learning, utilizing three leading Convolutional Neural Network (CNN) architectures: ResNet 50, EfficientNetV2, and MobileNetV3. Before classification, each multispectral image was processed through color segmentation in HSV space to highlight the dominant spectral, especially in the hue range of 110 170. The model was trained using a data augmentation scheme and optimized with the Adam algorithm, a batch size of 32, and a sigmoid activation function. The dataset consists of 807 images, including 295 H₂O images and 512 H₂O with NaOH images, which were divided into training (64%), validation (16%), and testing (20%) data. Experimental results show that ResNet50 achieves the highest performance, with an accuracy of 93.83% and an F1 score of 93.67%, particularly in identifying alkaline pollution. EfficientNetV2 achieved the lowest loss (0.2001) and exhibited balanced performance across classes, while MobileNetV3, despite being a lightweight model, remained competitive with a recall of 0.97 in the H₂O with NaOH class. Further evaluation with Grad CAM reveals that all models focus on the most critical spectral areas of the segmentation results. These findings support the effectiveness of combining color-based segmentation and CNN in the spectral classification of liquids. This research is expected to serve as a stepping stone in the development of an efficient and accurate automatic liquid classification system for both laboratory and industrial applications.

Abstract

 Penelitian ini bertujuan untuk melacak gagasan awal kemunculan aliran realisme sosialis di dunia Arab. Melalui penelitian ini, peneliti membuktikan bahwa meskipun aliran realisme sosialis itu muncul di Eropa pada masa modern, namun sesungguhnya di kalangan sastrawan Arab sejak era jahiliah, gagasan atau ide yang sejalan dengan aliran realisme sosialis sudah ditemukan di kalangan para sastrawan yang bergabung dalam sebuah komunitas yang diberikan nama sebagai as-Sha’alik. Dengan demikian, melalui penelitian ini, peneliti menarik kesimpulan bahwa para sastrawan Arab sejak periode awal sudah menerapkan nilai-nilai realisme sosialis dalam kreatifitas sastranya, walaupun mereka saat itu belum menamakannya dengan istilah tertentu. Di antara bukti-bukti untuk mendukung kesimpulan tersebut adalah bahwa ide yang diusung dalam karya sastra bukan hanya untuk mengeksplorasi tentang perasaan ataupun ide si penulis secara personal, namun juga merepresentasi aspirasi kelompok masyarakat lemah yang termarjinalkan. Artinya, gagasan yang diusung oleh para sastrawan as-Sha’alik ini lebih cenderung pada respon mereka terhadap persoalan sosial kemasyarakatan, kritik terhadap orang-orang kaya yang kikir ataupun penguasa dan pembelaan terhadap kaum lemah yang tertindas. Penelitian ini tergolong ke dalam jenis penelitian kualitatif. Adapun metode pengumpulan datanya dilakukan dengan tehnik penelitian pustaka (library research) dengan cara pembacaan terhadap sumber-sumber primer dan sekunder, baik dalam bentuk buku ataupun jurnal, yang berkaitan dengan permasalahan penelitian. Sedangkan pendekatan yang digunakan adalah analisis kritis historis yang bertujuan untuk melacak akar realisme sosialis dalam tradisi sejarah sastra Arab era jahiliyah. Dengan demikian melalui penelitian ini, penulis menyimpulkan bahwa orientasi karya sastra yang cenderung pada pembelaan terhadap kaum yang lemah merupakan fakta sejarah yang tidak dapat dinafikan keberadaannya dalam tradisi sastra Arab di era jahiliyah, sehingga ketika terjadi persentuhan dua tradisi sastra, Arab dan Eropa, di era modern maka dengan mudah realisme sosialis bisa diserap sekaligus diterapkan oleh para sastrawan Arab era modern, bahkan era kontemporer.
