Abstract

This study aims to determine the profile of mastery of physics concepts for Chemical Engineering Diploma III students at the Bandung State Polytechnic (POLBAN) because of the DIBeK&P2D learning model. The research subjects were DIII students of Chemical Engineering POLBAN. The study was carried out using a quasi-experimental method and a pre-test-post-test design for the control group. The results showed the highest mastery of concepts because the research learning model occurred on the topic of work-energy, followed by Boyle's law, AC power factor, fluid, mechanical heat tare, Joule's law, power in the resistor circuit, and the lowest occurred in the introduction. Because of the conventional learning model, the highest mastery of concepts occurs in Boyle's law, followed by energy work, fluid, AC power factor, power in resistor circuits, mechanical heat tare, preliminary and lowest occurs in Joule's law. Mastery of physics concepts because the research learning model is higher than conventional learning models. Conceptual mastery on learning topics is strongly influenced by the level of relevance and suitability between the characteristics of the topics as learning materials and the characteristics of the learning methods used, including evaluation content to measure the increase in students' mastery of concepts as learning products.

Abstract

The study purpose was to determine the change in the air density value (compressibility) when interacting with water in an open manometer venturi system. In this experimental study, the difference in water height of the manometer arms was conditioned as dependent variable, the diameter of the venturi tube and the mechanical power were conditioned as 2 independent variables where one changed the other was constant, and the density of air was conditioned as a moderate variable. The research shows: (1) the air density affects the relationship between the difference in water surface height and diameter where the value decreases as the diameter increases and the mechanical strength remains constant, the mean gradient is -6.31E-02 kg/m4 for the convergent pattern and -6.87E-02 kg /m4 for the divergent pattern, the mean of determination coefficient is 43.6% for the divergent pattern and 44.4% for the divergent pattern; 2) the air density affects the relationship between the difference in water level and the mechanical power, where the value decreases when the mechanical power increases but the diameter remains constant, the mean gradient is -5.45E-05 kg/m3W and the mean of determination coefficient is 45.9%.

Abstract

Penelitian tentang analisis respon mahasiswa jurusan teknik mesin angkatan 2020 Politeknik Negeri Bandung terhadap penggunaan aplikasi Phet Simulation pada praktikum keseimbangan telah dilakukan. Tujuan penelitian ini adalah untuk menganalisa respon penerimaan mahasiswa dan menguji kebermanfaatan aplikasi Phet Simulation pada praktikum keseimbangan mata kuliah fisika terapan. Jenis penelitian yang dilakukan merupakan penelitian pengembangan. Adapun metode yang digunakan diantaranya studi pengembangan modul praktikum momen gaya dan keseimbangan, pembuatan modul disertai video pengantar petunjuk praktikum, pengujian modul oleh mahasiswa, dan survey respon mahasiswa menggunakan kuisioner. Survey yang dilakukan terdiri dari survey pilihan persetujuan dan survey tanggapan verbal tertulis. Berdasarkan hasil survey dapat disimpulkan 82,8% mahasiswa jurusan Teknik Mesin Politeknik Negeri Bandung menerima dan merasakan manfaat penggunaan aplikasi Phet Simulation pada kegiatan perkuliahan praktikum keseimbangan mata kuliah fisika terapan.
