RANCANG BANGUN SISTEM INFORMASI PEMESANAN TRAVEL AR-RIYADH BERBASIS WEB MENGGUNAKAN MODEL USER CENTERED DESIGN
Get PDFOne of the shortcomings of Ar-Riyadh travel is the lack of integration with sophisticated information technology. Companies face problems because the travel booking system still relies on manual processes. Customers make travel reservations via WhatsApp by contacting the travel operator, which is not yet computerized, thereby presenting the risk of loss and damage to data in stored archives. The aim of this research is to design a web-based Ar-Riyadh travel booking information system using a User Centered Design (UCD) approach. The research results show that this system has succeeded in making it easier for users to implement the travel booking information system and making the booking process easier

Analysis of physics learning in elementary schools and the need for professional development: Is STEM education training necessary for elementary school teachers?
Get PDFThis study aims to explore pedagogical approaches and students’ engagement during STEM teaching. As many as 215 elementary school teachers in West Java were involved in this research. Those involved consisted of 161 women and 49 men. The majority of teachers have an elementary school teacher education background (87%), 7% have other educational backgrounds (Science Education/Mathematics Education/Social Education/Language Education), and the remaining 6% are in the sciences. The instrument used in this study was a closed questionnaire with 20 items from a Likert scale survey. The results of the study show that 50% of elementary school teachers very rarely use experimental approaches and problem-based learning when teaching STEM content. More than 60% of teachers also very rarely use the inquiry approach in teaching the four contents. The approach that is often used by teachers in teaching STEM is a collaborative and integrated approach. In addition, the survey results also show that more than 50% of students are very rarely involved in inquiry and engineering practice activities when learning about STEM content. The analysis of professional development needs showed that the majority of elementary school teachers have never received a professional development program regarding STEM education. In fact, the majority of teachers have a positive attitude towards the coaching program, which has an impact on increasing their competence. Apart from that, the results of this research also show that there is a lack of external support (from universities, educational practitioners, and researchers) for teachers in coaching programs. These findings provide evidence that teachers still need to receive training on pedagogical approaches that are relevant to integrated STEM education. The existence of training on STEM education is expected to improve the quality of STEM learning in the classroom. Thus, students\u27 involvement in scientific and engineering practice when learning STEM becomes more dominant
PISA science framework 2018 vs 2025 and its impact in physics education: Literature review
Get PDFProgram for International Student Assessment (PISA) evaluates education systems in participating countries. Junior high school students are tested in math, science, and reading for the PISA Scientific Literacy test. This study contrasts the PISA Science Framework 2018 and 2025. This literature research uses systematic Literature Review (SLR) and bibliometric analysis. The method finds, reviews, evaluates, and interprets all research related to scientific literacy, PISA Framework 2018 and 2025, and its impact on Physics Education. The research used the Scopus database to find PISA Science Framework-related scientific articles. Results showed that PISA Framework 2025 evolves science literacy and scientific information function. The language is simplified to be more coherent by emphasizing the main idea of science. Procedural and epistemic knowledge are expanded and clarified. The finding is also supported by VOSviewer visualization of data results. This framework implies that physics education will assess students\u27 understanding of fundamental physics principles and their rationality in applying them, including decision-making. In conclusion, the PISA Science Framework 2018 needs to be updated to the PISA Framework 2025 by the OECD to accommodate the students\u27 needs in this era

The results of this research show that auditor competency does not influence audit quality, objectivity influences audit quality, audit fees do not moderate the relationship between competency and audit quality, audit fees do not moderate the relationship between objectivity and audit quality
INVESTIGASI PERBANDINGAN COSINE SIMILARITY DAN EUCLIDEAN DISTANCE DALAM DETEKSI PHISHING ATTACK MENGGUNAKAN METODE K-NEAREST NEIGHBOR
Get PDFThe development of information technology affects various aspects of life. However, this positive impact also opens up opportunities for growing cybercrime, known as cybercrime (Iman et al., 2020). These crimes, such as carding, hacking, and phishing, threaten security in the digital realm (Gulo et al., 2021). Phishing, as a form of cybercrime, involves sending fake links to steal victim information (Wibowo & Fatimah, 2017). In the midst of the development of information technology systems, data mining has emerged as a solution, enabling all valuable information from big data. K-Nearest Neighbors (KNN) is a machine learning algorithm used for classification and regression (Dewi Obert & Gusmana, 2018). In K-Nearest Neighbor, distance methods such as euclidean distance, Manhattan distance, cosine similarity, and jaccard similarity are commonly used. The focus of this research is on euclidean distance and cosine similarity which are considered efficient and commonly used. The evaluation results show that the second method, cosine similarity and Euclidean distance, has a similar level of accuracy and speed in detecting phishing attacks. However, Euclidean distance stands out in phishing detection with an accuracy rate of 87.70% and a speed of 0.0172. Meanwhile, cosine similarity reaches an accuracy rate of 87.57% with a speed of 0.0360. Looping analysis consistently confirms the Euclidean distance speed advantage. In phishing attack detection, Euclidean distance is proven to be more effective in accuracy and speed
Pengaruh Penambahan Tepung Daun Mengkudu (Morinda citrifolia L) dan Tepung Jintan Hitam (Nigella sativa) terhadap Kualitas Eksterior Telur Puyuh
Get PDFTanaman herbal adalah tanaman yang mempunyai nilai lebih dalam pengobatan karena mengandung zat-zat bioaktif yang baik untuk tubuh. Tujuan penelitian ini adalah untuk mengetahui kemampuan daun mengkudu dan jintan hitam dalam meningkatkan kualitas eksterior telur puyuh. Materi yang digunakan adalah puyuh strain Autumn sebanyak 96 ekor umur puyuh 66 hari. Masing-masing terdapat 6 ekor untuk setiap unit percobaan. Metode penelitian menggunaan rancangan acak lengkap (RAL) terdiri dari 4 perlakuan dan 4 kali ulangan yaitu P0 (Pakan Basal), P1 : Pakan Basal + 3% Tepung Daun Mengkudu + 1% Tepung Jintan Hitam, P2 : Pakan Basal + 2% Tepung Daun Mengkudu + 2 % Tepung Jintan Hitam, P3 : Pakan Basal + 1% Tepung Daun Mengkudu + 3 % Tepung Jintan Hitam. Analisis ragam menunjukkan bahwa perlakuan berpengaruh tidak nyata (P>0,05) terhadap indeks telur, bobot telur dan tebal kerabang. Kesimpulan dari peneltian ini adalah penambahan tepung daun mengkudu (Morinda citrifolia L) dan tepung jintan hitam (Nigella sativa) tidak terlalu mempengaruhi kualitas eksterior telur puyuh.
