Abstract

Landslides were addressed as one of the natural hazards that can create extensive disasters. Effective assessment to locate potential landslide events is crucial for planning and risk mitigation. This study, which is located in the Sumitro watershed, Kulon Progo, Yogyakarta, presents a novel approach to landslide susceptibility assessment by integrating the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model (TRIGRS) with the Flow-R model. Five key parameters, namely slope, soil properties, groundwater level, soil thickness, and rainfall, were used to create the landslide susceptibility zonation. TRIGRS was used to identify the landslide initiation, while Flow-R was used to create the run-out area. The result was then validated through statistical evaluation using Area Under Curve (AUC) based on the landslide inventory. Results show that landslide susceptibility zonation created from TRIGRS alone resulted in an AUC value of 0.679, while the combination of TRIGRS-Flow-R susceptibility zonation shows a better AUC value of 0.728. The increase of the AUC value of almost 0.05 has enhanced the correlation between the landslide susceptibility zonation and landslide inventory from “acceptable” to “excellent” correlation. This result demonstrates that integrating Flow-R with TRIGRS improves the performance of landslide susceptibility zonation. This study offers a new perspective on creating landslide susceptibility zonation by combining two methods, yielding more reliable results. Doi: 10.28991/CEJ-2025-011-03-020 Full Text: PDF

Abstract

This study aims to examine the application of the drill method in teaching Arabic to MTsN 9 Kediri. The drill method, emphasizing repetitive practice, is believed to strengthen memory retention and enhance students' Arabic language skills, particularly in vocabulary (mufrodat), grammar (qawaid), pronunciation, and speaking ability. This research uses a descriptive qualitative approach, with the Arabic language teacher as the subject and the practice of the drill method during the even semester of the 2024/2025 academic year as the object. Interview results show that the drill method effectively improves student participation and retention of Arabic material. Students demonstrated enthusiasm, positive responses, and significant improvement in pronunciation and sentence structure mastery. The results of this study are expected to provide strategic input for teachers in selecting effective Arabic teaching methods at the madrasah level.

Abstract

The rapid development of digital banking technology requires improvements in service quality to remain competitive in the financial industry. Seabank Indonesia is one of the widely used digital banking applications, making sentiment analysis of user reviews an essential aspect of understanding their perceptions of the provided services. This study evaluates user sentiment toward the Seabank application by implementing the Naïve Bayes algorithm to optimize service quality. The research data was obtained through a web scraping process from the Google Play Store, totalling 1,000 reviews. The Knowledge Discovery in Databases (KDD) approach was applied in the analysis, encompassing preprocessing stages such as cleaning, casefolding, tokenization, stopword removal, stemming, and Term Frequency-Inverse Document Frequency (TF-IDF) representation. The classification model was built by splitting the dataset into 70% training and 30% test data. The evaluation results indicate that the developed model achieved an accuracy of 88%, with a precision of 95%, recall of 87%, and F1-score of 91%. An analysis of all reviews revealed that 70.5% were positive, while 29.5% were negative. These findings demonstrate that the Naïve Bayes algorithm is effective in analyzing user sentiment and provides valuable insights for developers to enhance the quality of Seabank Indonesia’s services.

Abstract

Undang-Undang Nomor 11 Tahun 2020 tentang Cipta Kerja merupakan bagian dari Omnibus Law. Yang dimaksud dengan undang-undang Omnibuslaw adalah peraturan perundang-undangan yang dimodifikasi untuk mencakup segala sesuatu atau undang-undang yang mengatur banyak hal. Penulis mengangkat judul ini karena ingin mempertanyakan dampak undang-undang hak cipta terhadap pusat pekerjaan, hubungan antara perusahaan dan karyawan. Omnibus Law UU Cipta Kerja Nomor 11 Tahun 2020 sempat menjadi perdebatan publik karena ditolak oleh banyak kalangan di negeri ini. Dan saat ini masih banyak masyarakat yang belum memahami tentang hukum cipta kerja. Saat ini, masyarakat hanya mengonsumsi cerita rakyat. Negara kita seperti tali yang kedip-kedip, mudah terprovokasi dan dipropagandakan oleh pernyataan-pernyataan.
