Analysis of the influence of amplitude, frequency, angle of propagation, and air pressure on the characteristics of sound waves
No full textThis study offers a comprehensive approach that has not been widely explored, integrating PhET interactive simulations and the Phyphox sensor application to analyze the simultaneous influence of four physical parameters amplitude, frequency, dispersion angle, and pressure on the characteristics of sound waves. The integration of PhET interactive simulations and the Phyphox application enables real-time visualization and experimental data measurement through smartphone sensors. Furthermore, this research contributes new insights by exploring the dispersion angle in the context of wave direction and intensity, a topic rarely discussed in digital media-based acoustic studies. The method used is a quantitative experiment with amplitude variations from 1 to 10 and frequencies of 400 Hz, 500 Hz, and 600 Hz, measured at distances of 1 cm, 3.25 cm, and 5.5 cm. The study also includes observations of reflection and interference patterns of waves at propagation angles of 18°, 45°, and 90°, as well as an analysis of the effect of air pressure on sound intensity, with pressure varied from 0.0 atm to 1.0 atm. The results show that sound wave intensity increases with higher amplitude and frequency, in accordance with the theory that intensity is proportional to the square of the amplitude. The propagation angle influences the reflection and interference patterns, resulting in varied energy distribution. Additionally, air pressure significantly affects sound intensity, emphasizing the crucial role of the medium in sound wave propagation

Penggunaan Komposit Karbon Aktif Termodifikasi Kitosan/Alginat Beads sebagai Adsorben Rhodamin B
No full textActivated carbon is one of the adsorbents that has a large surface, high porosity, and various functional groups on its surface. However, synthesized activated carbon is generally a powder that is difficult to separate from water, so it has low reuse effectiveness. Therefore, it is necessary to modify it to increase its adsorption effectiveness and also increase its adsorption capacity. One of them uses chitosan and activated carbon into beads, as shown in previous studies that reported high adsorption capacity of methylene blue (MB) dye. This modification is relevant to handle the problem of industrial wastewater containing hazardous dyes, such as rhodamine B, which has high stability and is difficult to biodegrade. This study aims to analyze the adsorption process of rhodamine B using KAKatea composite beads focusing on the optimum conditions, isotherm model, and reuse effectiveness. The results showed that the optimum conditions of adsorption were at a contact time of 210 minutes and rhodamine B pH of 3. This adsorption process followed the Freundlich isotherm model with reuse effectiveness reaching 82% for five cycles.Karbon aktif merupakan salah satu adsorben yang memiliki permukaan besar, porositas tinggi, dan berbagai gugus fungsi pada permukaannya. Namun, karbon aktif hasil sintesis umumnya berbentuk serbuk yang sulit dipisahkan dari air, sehingga memiliki efektivitas penggunaan kembali rendah. Oleh sebab itu, perlu adanya modifikasi untuk meningkatkan efektivitas adsorpsinya dan juga dapat meningkatkan kapasitas adsorpsinya. Salah satunya menggunakan kitosan dan karbon aktif menjadi berbentuk beads, sebagaimana ditunjukkan dalam penelitian terdahulu yang melaporkan kapasitas adsorpsi tinggi terhadap zat warna metilen biru (MB). Modifikasi ini relevan untuk menangani permasalahan limbah cair industri yang mengandung zat warna berbahaya, seperti rhodamin B, yang memiliki stabilitas tinggi dan sulit terurai secara hayati. Penelitian ini bertujuan untuk menganalisis proses adsorpsi rhodamin B menggunakan komposit beadsKAKatea yang berfokus pada kondisi optimum, model isoterm, dan efektivitas penggunaan kembalinya. Hasil penelitian menunjukkan bahwa kondisi optimum adsorpsi pada waktu kontak 210 menit dan pH rhodamin B sebesar 3. Proses adsorpsi ini mengikuti model isoterm Freundlich dengan efektivitas penggunaan berulang mencapai 82% selama lima siklus
