Abstract

Madu merupakan cairan menyerupai sirup yang dihasilkan oleh lebah madu dari sari bunga tanaman (flora nektar) atau bagian lain tanaman.Kandungan gula pada madu berasal dari fruktosa dengan persentase terbanyak, glukosa dan sukrosa dengan persentase sedikit. Madu banyak dikonsumsi oleh masyarakat mulai dari bidang kesehatan, kecantikkan maupun industri. Tujuan dari penelitian ini adalah untuk mengetahui cara menentukan kemurnian beberapa madu dengan indeks bias. Penelitian ini dilakukan dengan cara mengukur indeks bias madu dengan metode pembiasan. Analisis data didapat dengan mencari indeks bias rata-rata madu kemasan merk TJ dan madu hutan Harokah pada sudut datang 200 dan 400 .Hasil penelitiandidapat nilai indeks bias madu kemasan merk TJ lebih besar dari indeks bias madu hutan Harokah. Sehingga dapat disimpulkan bahwa madu kemasan merk TJ lebih murni dari pada madu hutan Harokah. Kata kunci :Madu, Pembiasan, Indeks bias, Kemurnian larutan

Abstract

This research was conducted aiming to determine the critical thinking skills of Teacher Training and Education Department Syiah Kuala University physics students based on critical thinking indicators in solving optical geometry problems. This research uses a quantitative approach with descriptive research methods. The population of this research is the 2016 Physics Education students as many as 57 students with 40 students as a sample of respondents. Data collection was performed using a test consisting of 5 essay questions that have been validated for use as an instrument for critical thinking tests. The data obtained is then averaged per indicator and then presented and then categorized using the criteria table for critical thinking skills. The results show the average percentage of values obtained by students in solving optical geometry problems for each critical thinking ability is 43% in the ability to provide an explanation simple, 33% in the ability to build basic skills, 25% in the ability to conclude, 33% in the ability to provide further explanation, and 13% in the ability to formulate strategies and tactics. Based on these results it can be concluded that the critical thinking ability of students based on each indicator in the physics education student at Teacher Training and Education Department Syiah Kuala University is still low.

Abstract

Learning in the Covid-19 era requires lecturers and students not to study in the same place. This condition is a new challenge for lecturers and students to continue implementing effective learning using a suitable approach that is blended learning. This research is a preliminary study to determine the difficulties of lecturers in implementing blended learning at Department of Physics Education, FKIP – Universitas Syiah Kuala. The method used in this research is a survey using a questionnaire containing 30 statements. The indicators measured in this study were 9 (nine) indicators from 2 aspects, namely the readiness and skills of lecturers in implementing blended learning in the Covid-19 era. The questionnaire was distributed to 15 lecturers in the Department of Physics Education, and the results of the responses obtained were analyzed using descriptive statistics. The results of the analysis show that 29.23% of lecturers are not ready to apply the blended learning approach because 53.85% of lecturers rarely access the internet and learning platforms to facilitate lecture activities, so they are not used to using it. 44% of lecturers are not yet skilled in using learning platforms which are shown by 46.16% of lecturers having difficulty changing the general appearance of the virtual class, and 46.15% of lecturers have difficulty interacting using the learning platform. These difficulties are the obstacles for lecturers to apply the blended learning approach in lecture activities, so it is necessary to immediately find solutions to help the lecturer difficulties so that lectures in the Covid-19 era continue to run effectively like previous lectures.Keywords: Blended Learning, Covid-19, Lecturer Difficulties, Obstacles
