Abstract

It is known that the 'electronic structure of atoms' in material physics is microscopic. This atomic structure has an abstract and complicated concept, therefore good analogy skills are needed to study comprehensively. This research develops a free analogy-based material physics module to supply analogy skills to prospective physics teacher students. Module development uses the 4D model namely Define, Design, Development and Disseminate. The feasibility aspects are required based on the presentation, content, and grammar. Data obtained from expert assessment and trials using questionnaires, interviews, and tests. Increased student analogy skills were analyzed using normalized N-gain. The results obtained are: (1) the characteristics of the module that has learning steps such as teaching with analogy models, namely: introducing the concept of targets, reviewing the concept of analogies, identifying the relevant nature of targets and analogies, mapping analogies with targets, identifying analogies that are not relevant to targets, and make conclusions, (2) module quality on atomic electronic structure material developed is categorized as feasible, (3) modules are proven to increase mastery of the concept of atomic electronic structure (N-gain = 54%) and analytical skills prospective teachers physics (N-gain = 56%). The development of physics modules based on free analogies can be applied to other learning, such as biology, chemistry, and mathematics to explain abstract material.

Abstract

Peneltian ini bertujuan menganalisis spektrum Fourier Transform Infra Red (FTIR) dan menentukan minimum loss dari kaca Tellurite-Bismuth-Zinc-Plumbum (TBZP) yang dipengaruhi oleh variasi (PbO). Kaca TBZP difabrikasi dengan teknik melt quenching dengan komposisi 55TeO2–2Bi2O3–[43-x]ZnO–xPbO (%mol) dengan x=2, 3, 4, 5. Hasil uji spektrum Fourier Transform Infra Red (FTIR) menunjukkan pita absorbsi terbesar berada pada panjang gelombang lebih dari 620nm. Absorbansi tersebut lebih diakibatkan oleh adanya transisi vibrasi pada daerah infrared. Minimum loss pada kaca TBZP diprediksikan secara teoritis melalui fitting data infrared edge dengan kurva Rayleigh scattering. Minimum loss kaca TBZP sebasar 2,94 dB/km hingga 2,35 dB/km pada λ=5534,2nm hingga 5821,2nm. Nilai minimum loss menurun seiring pertambahan konsentrasi ion Pb2+ dalam kaca TBZP. Sifat tersebut menjadikan kaca ini sebagai kandidat yang baik untuk aplikasi yang menggunakan gelombang infrared seperti fiber optik infrared. The aims of this research were to analyze the spectrum of Fourier Transform Infra Red (FTIR) and determine the minimum loss of Tellurite-Bismuth-Zinc-Plumbum (TBZP) based glass which affected by the variation of (PbO). The TBZP glass has been fabricated by melt quenching technique with composition 55TeO2–2Bi2O3–[43-x]ZnO–xPbO (mol%) with x=2, 3, 4, 5. Fourier Transform Infra Red (FTIR) spectra test results showed that the greatest absorption bands were at wavelengths over 620nm. Vibrational transition has the reason behind the absorbance in the infrared region. Minimum loss on glass TBZP theoretically was predicted by fitted data from the infrared edge and rayleigh scattering curve. The minimum loss of TBZP was of the range 2,94 dB/km to 2,35 dB/km at λ=5534,2nm to 5821,2nm. The minimum loss of TBZP glass decreases as the Pb2+ content in glass increases. This makes these glasses are good candidate for IR-application such as infrared optical fiber.

Abstract

The phenomenon in the classroom where teachers are still limited space to train and to improve students' creative thinking skills (CTS) on the topic of material elasticity is the main reason for this research. Information on improving students' creative thinking skills in material elasticity topics by implementing problem based learning model (PBL) in learning is also limited. Previous research has not revealed any effort related to improving students' creative thinking skills on material elasticity topics by comparing two different learning models. Therefore this study aims to reveal differences in student learning outcomes on material elasticity materials in PBL and conventional models. Based on the research results obtained information that students 'creative thinking skills scores using PBL model is higher compared with that of conventional learning. It also revealed at each meeting that the CTS indicator of students are always improve. It can be concluded that PBL is very effective in training and improving students' creative thinking skill in physics learning. Thus PBL can be recommended in improving students' creative thinking skills.

Abstract

Dalam penelitian ini telah dikembangkan multimedia interaktif pada konsep kalor. Penelitian ini bertujuan menganalisis pengaruh multimedia interaktif dan gaya belajar terhadap penguasaan konsep kalor siswa. Penelitian dilaksanakan dalam tiga tahapan, yaitu studi pendahuluan, pengembangan desain, dan pengujian model. Pada tahap pengujian model digunakan metode kuasi eksperimen. Data yang diperoleh dianalisis menggunakan ANAVA dengan dua faktor, yaitu model pembelajaran dan gaya belajar. Gaya belajar siswa dibagi menjadi empat kategori berdasarkan model VARK Fleming, yaitu Visual, Auditori, Read, dan Kinestetik. Hasil penelitian menunjukkan bahwa rata-rata penguasaan konsep siswa yang belajar menggunaan multimedia interaktif lebih tinggi dibandingkan siswa yang belajar tanpa multimedia. Penguasaan konsep kalor siswa juga dipengaruhi oleh gaya belajar, dimana siswa dengan gaya belajar visual memiliki penguasaan konsep yang lebih tinggi dibandingkan siswa dengan gaya belajar lainnya.In this research, we have developed interactive multimedia on heat concepts. This research aimed to analyze the effect of interactive multimedia and learning styles towards students’ understanding on heat concepts. The research was conducted in three stages: a preliminary study, development, and testing of models. Testing phase of the model used a quasi-experimental method. Data were analyzed using ANOVA with two factors, namely learning models and learning styles. Students' learning styles were divided into four categories based on the model VARK Fleming; Visual, Auditory, Read, and Kinesthetic. The results showed that the average of students’ understanding who learned using interactive multimedia was still higher than students who learned without interactive multimedia. Students’ understanding on heat concepts were affected by learning styles, in which students with visual learning styles had higher understanding on heat concepts that students with any other learning styles.

Abstract

Energy is one of the basic concepts in physics which is included as an abstract concept that is not easily captured by students to its physical properties. Therefore it is necessary to optimize the experimental tool in physics learning, especially in the learning of mechanical energy to facilitate understanding the concept. Technology research is growing rapidly and is able to contextually present abstract phenomena that are sensor-based technology and one of them is an ultrasonic sensor. This study aims to develop a mechanical energy experimental tool using ultrasonic sensors to facilitate students in understanding the concept of energy. The development of the experimental tool used research and development methods. To test the feasibility of the experimental tool developed and the accompanying practicum module, a series of feasibility tests have been carried out including calibration tests, feasibility tests by physicists, and empirical tests by users. The instrument used is a checklist item compiled based on the standard indicators of the feasibility of an experimental tool. The results of the development showed that the experimental tool had a precision percentage of 98.1% and a high accuracy of 99.99% with a value of t = (0.383 ± 383X10-4) s. Based on the feasibility test by physicists 93.75% of indicators as standardized experimental tools have been achieved, as well as the experimental modules fulfilling 90.90% of the standard set. Similar results were also report by users that the experimental tool was feasible to be used in schools’ level, but there were still obstacles related to the sensitive nature of ultrasonic sensors with surrounding movements and constraints in making variable variations to be tested which had an impact on the less optimal graphic display.Energi merupakan salah satu konsep dasar fisika yang memiliki sifat abstrak yang sulit ditangkap makna fisisnya oleh siswa.
