Abstract

The objective of the study is to determine the characteristic of moisture sorption isotherm from "gaplek" flour fortified with protein from red bead tree flour using various modeling and being observed from the monolayer moisture content and its absorption types. This research used 5 salt solutions and storage temperature of 298K, 308K, and 318K. The models used were Brunauer-Emmet-Teller (BET), Guggenheim-Anderson-de Boer (GAB) and Caurie model. The monolayer moisture content was around 5.07 – 8.53% db. kb value of GAB model was around 0.5941-0.6252. c value of GAB model was around 16.0588-23.4111. C value of BET was around 32.7241-306.5000. Whereas the c value in Caurie model was around 1.1419-1.2769. The equilibrium and monolayer moisture content on ‘gaplek" flour fortified with protein from red bead tree flour was decreasing as the temperature going up. GAB constant value indicated that the process of moisture absorption on the "gaplek" flour fortified with protein from red bead tree flour categorized in type II.

Abstract

Blended-Flipped Classroom Learning is a learning method that combines blended learning with flipped classroom learning. This study aims to: (1). Design and implement Blended-Flipped Classroom Learning with the topic of Photoelectric Effect for Physics and Physics Education students in Modern Physics course; (2). Determine how the effect of Blended-Flipped Classroom Learning on student learning outcomes for the topic of Photoelectric Effect; (3). Determine students’ responses toward Blended-Flipped Classroom Learning for the topic of Photoelectric Effect. This research was descriptive and conducted at the Physics and Physics Education Department, Universitas Kristen Satya Wacana in the Modern Physics course. From the results of the research conducted it can be concluded that student learning outcomes after Blended-Flipped Classroom Learning were in the “high” and “very high” category, where most students (85.7%) were in the very high category. This result indicates that learning using Blended-Flipped Classroom Learning helps students to achieve optimal learning outcomes. Student responses to Blended-Flipped Classroom Learning were in the “good” category. It also shows that students' positive responses to the learning process can influence the optimization of their learning outcomes. This kind of learning model requires the teacher who acts as a facilitator, dynamist, evaluator and also justifier.

Abstract

Physics learning about simple harmonic motion on a pendulum swing is interesting to be deeply learned because there are various physical quantities, practicum, formula derivation, and representation. In online learning, inquiry physics learning that provides independent practicum, online access, systematics, and interactive is needed. This research aims to design Golabz-based interactive learning and investigate its effect on students' understanding of simple harmonic motion on a pendulum swing. This research uses the RD methods of the ADDIE type. The respondents were 7 second-year undergraduate students of the Department of Physics Education, UKSW, randomly chosen. The research instruments used are a validation sheet of material and media experts, an observation sheet, an evaluation sheet, and a questionnaire. All data gathered are analyzed using the qualitative descriptive technique. The result showed that the material and media met the eligibility criteria of 70,66% and 78,66%; all respondents can do 88,8% learning on average; all respondents can give positive responses of 89,79% on average in the questionnaire; and all respondents get evaluation score of 91,84% in average. Thus, Golabz-based interactive learning design is adequate to help students understand simple harmonic motion on a pendulum swing and can be one of the alternative online learning that presents interactive inquiry learning.

Abstract

There are many virtual physics laboratory applications, i.e., Golabz and Crocodile Physics. This study aims to design online physics learning about RLC series circuits using Golabz, which integrates Crocodile Physics and investigates its effectivity on students' understanding. The research method used here is the development research with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The online physics learning design based on an inquiry about the RLC series circuit using Golabz consists of three learning activities according to the learning objectives. Each learning has five steps, i.e., orientation, conceptualization, investigation, discussion, and conclusion. The research instruments are an observation sheet, evaluation, questionnaire, and validation sheet for the material and media. Based on the research above, the results of learning observation indicate that all respondents can follow the learning well with an average of 82% and gave positive responses to at least 70% of the statements with an average of 98%; some students were able to obtain evaluation results of more than 70% with an average of 71.88%. Thus, all indicators of success are achieved, and the online physics learning design about RLCseries circuits using Golabz is said to be sufficient to help students understand the material of RLC series circuits.

Abstract

Penilaian hasil pembelajaran dibutuhkan untuk membuat keputusan dalam pembelajaran. Banyak pengajar mengabaikan cara penilaian hasil belajar, dengan soal-soal yang tidak mencerminkan kemampuan siswa. Penelitian ini memberikan sebuah contoh cara menganalisa soal Fisika yang digunakan untuk mengukur kemampuan siswa dengan tepat. Banyak tehnik penilaian sudah dikembangkan untuk menilai pencapaian kompetensi hasil belajar siswa. Analisa teori respon butir atau Item Response Theory (IRT) merupakan salah satu analisa yang dapat digunakan untuk melihat ketepatan soal. Penelitian ini akan menggunakan pendekatan model Rasch. Model Rasch mengacu pada tingkat kesulitan butir soal (b) tiap item soal, dan daya beda butir soal (a) yang sama untuk seluruh item soal. Analisa butir soal menggunakan 16 butir soal Fisika pada media pembelajaran Fun Frame in Physics (FFP). Butir soal diujikan kepada 99 siswa SMP dan dianalisa menggunakan program R, dengan hasil daya beda butir soal (a) sebesar 0,815 , tingkat kesulitan butir rata-rata (brata2) -0,331 dengan standar deviasi 1,232552. Hasil pengkategorian soal didapatkan, soal dikatakan sangat sulit jika b > 0,902, soal dikatakan sulit jika -0,331 < b < 0,902, soal dikatakan mudah jika -1,564 < b < -0,331 dan soal dikatakan sangat mudah jika b < -1,564. Kesimpulan tigkat kesulitan soal FFP adalah 25% soal sangat mudah, 37,5% soal mudah, 12,5% soal sulit, dan 25% soal sangat sulit. Karakeristik butir soal ditampilkan juga dalam bentuk fungsi informasi.Grafik fungsi informasi butir menunjukkankan bahwa gambaran karakteristik soal yang dibangun dari respon siswa terlihat mampu menggambaran kemampuan siswa, tercermin melalui nilai informasi tertinggi untuk tiap soal.
