Abstract

Penelitian ini bertujuan untuk menganalisis aliran udara pada rongga hidung akibat penyakit sinusitis. Penyakit sinusitis adalah peradangan yang terjadi pada dinding sinus disebabkan oleh gaya hidup yang tidak sehat. Dampak sinusitis secara umum adalah gangguan sistem pernafasan akibat adanya penumpukan cairan pada rongga hidung. Akibat dari penumpukan cairan tersebut menyebabkan pembengkakan pada lapisan konka hidung yang terhubung langsung dengan organ sinus. Munculnya pemodelan matematika sebagai sebagai ilmu baru merupakan salah satu alternatif pemecahan masalah ini. Pemodelan matematika bertujuan untuk memperoleh formula yang menggambarkan keadaan aliran udara di rongga hidung sesuai dengan kondisi sebenarnya. Pemodelan matematika yang digunakan adalah menggunakan metode volume hingga. Metode volume hingga digunakan untuk menganalisis benda yang tidak terstruktur seperti aliran udara. Pada penelitian ini menggunakan bantuan software Matlab dan Fluent. Matlab digunakan untuk menampilkan menghitung numerik dan grafik hasil yang terjadi, sedangkan Fluent digunakan untuk memvisualisasikan keadaan yang terjadi. Hasil dari penelitian ini adalah untuk mengetahui aliran udara yang terjadi pada rongga hidung akibat penyakit sinusitis, semakin besar ketebalan penumpukan lendir pada dinding sinus maka kecepatan aliran udara yang dihasilkan semakin cepat. Hasil perhitungan menggunakan metode volume hingga didapatkan tingkat kesalahan kurang dari 0,001.

Abstract

The rapid development of technology sparks an increase in educational innovations, one of which is the use of interactive learning media. Interactive learning media is a tool to gradually improves the delivery of mathematics learning materials. This study aims to develop Scratch-assisted interactive learning media to improve students’ conceptual understanding of two-dimensional figures, especially rectangles and squares. This research employed Research and Development (R&D) model proposed by Thiagarajan. Data analysis in this study included analysis of validity, practicality, and effectiveness. A total average of 3.66 for media and 3.7 for test questions was assigned by the three validators, providing strong evidence for media validity. Likewise, strong practicality was evident as indicated by an average score of 87.89% from 28 students. Finally, the analysis marked N – Gain effectiveness of 66% for test results from 28 students, which corroborated that the media is effective. The results of analysis corroborated that interactive learning media assisted by scratch have proven valid, effective, practical, and demonstrate the potential to enhance students' understanding of rectangle and square concept.

Abstract

Educational digitalization is characterized by technology-assisted media, leading to improved students’ digital literacy. One of these media is the electronic worksheet for students. An initial observation revealed that learning activities at Public Islamic Senior High School (MAN) in Bondowoso still operationalized conventional books as the sole media. This study aimed to develop electronic worksheets for students using valid, effective, and practical Geogebra-assisted live worksheets, guided by the 4-D model designed by Thiagarajan. This model consisted of four stages, i.e., define, design, develop, and disseminate. Data were collected through observation, tests, and questionnaires. Test questions were used to determine the level of effectiveness, and questionnaires were used for validity and practicality tests. The results revealed very high validity. The effectiveness analysis exhibited an N-Gain percentage of 76%, signifying a satisfactory effectiveness rate. The practicality analysis marked 86.20%, which is classified into a good category. The analysis results corroborated that electronic worksheets for students have proven valid, effective, and practical, demonstrating the potential to improve students' digital literacy.
