Abstract

One of the students’ main obstacles in studying physics is their low self-efficacy. A person’s self-efficacy level affects their process of behavior selection, determining the amount of effort against obstacles, determining ways of thinking and emotional reactions, along with predicting future behavior. This study used a qualitative method with a descriptive approach. Teachers can use scaffolding to increase students’ self-efficacy in learning. Scaffolding is a series of activities carried out to help children learn. The teacher provides excellent assistance to students during the early stages of learning; then, the assistance is slowly reduced until students can learn independently.Keywords: self-efficacy, physics learning, scaffolding AbstrakSalah satu hambatan yang utama muncul dari dalam diri siswa ketika belajar fisika adalah self-efficacy siswa yang rendah. Tingkat self-efficacy seseorang memiliki peran dalam menentukan pemilihan perilaku, menentukan besarnya upaya terhadap hambatan, menentukan cara pikir dan reaksi emosional, dan prediksi perilaku yang akan muncul. Metode penelitian yang digunakan adalah metode penelitian kualitatif dengan pendekatan deskriptif. Guru dapat menggunakan scaffolding untuk meningkatkan self-efficacy siswa pada pembelajaran. Scaffolding merupakan serangkaian kegiatan yang dilakukan untuk membantu anak dalam belajar. Guru memberikan bantuan besar kepada siswa selama tahap awal pembelajaran kemudian seiring waktu bantuan perlahan dikurangi hingga siswa mampu melakukannya secara mandiri. Kata Kunci:  self-efficacy, pembelajaran fisika, scaffolding

Abstract

Students' multi-representational understanding in understanding glasses needs to be raised by educators in various forms of presenting information so that students are able to understand an abstract problem to become concrete in all realms of reflection. One way to apply learning with a multi-representational approach can have a positive influence on students' cognitive abilities which include low cognitive levels and high cognitive levels. The purpose of this research is to develop an e-module of  based on multiple representations for high school students' abstract thinking skills. This is to determine the success of module development that has been designed in such a way. The research method used is research and development or research and development. The model used in the development of this e-module is a 4D model which consists of four stages of development, name define, design, develop, and disseminate. The stages used in the development of this e-module reach the develop stage, due to research limitations and in accordance with the research objectives, namely the development of e-modules. From the results of the research and discussion, it can be concluded that several representation-based e-modules to improve the abstract thinking skills of high school students that have been compiled are of good quality and still need to be achieved. .

Abstract

With the Covid-19 Pandemic, the teacher's role is not only as a teacher in a formal school but is expected to be an agent of renewal in the face of a new normal where we must all be able to live with the coronavirus. This research aims to get an idea of teachers' experiences as community coaches or extensions and the most appropriate type of training during this pandemic. The data in this descriptive study was obtained from the spread of questionnaires to 16,546 respondents who were teachers at the early childhood education (PAUD) to high school (SMA) levels throughout Indonesia. Data processing and analysis were done descriptively and obtained some results. Notably, 77.8% of respondents have experience in providing training, and the most training materials ever given by teachers as coaches are about education, which is 88.9%. Related to the skills needed to act as a coach with material about life in the Era New Normal, most teachers assume that speaking in public, developing presentation materials, and using technology are skills that must be possessed. Furthermore, the study's results can be a reference for developing training forms with teachers as coaches or extensionists, especially in the New Normal era.

Abstract

Matahari merupakan sumber energi utama bagi kehidupan di Bumi. Perubahan aktifitas Matahari jangka panjang memegang peranan penting dalam perubahan iklim global. Perubahan iklim tersebut menyebabkan naik turunnya suhu di permukaan bumi. Pancaran cahaya Matahari tersebut membawa energi bahkan radiasi. Total radiasi yang diterima dipermukaan bumi dipengaruhi oleh jarak Matahari, intensitas radiasi Matahari, panjang hari. Jarak Matahari selalu berubah sepanjang tahun dikarenakan orbit Bumi mengelilingi Matahari berbentuk elips. Saat Bumi berada pada jarak terdekat dengan Matahari disebut perihelion. Saat Bumi berada pada jarak terjauh dari Matahari disebut aphelion. Penelitian ini bertujuan untuk mengetahui pengaruh aphelion dan perihelion terhadap suhu di kota Medan menggunakan weather station. Aphelion dan perihelion tidak memiliki dampak yang signifikan terhadap suhu Bumi. Ketika jarak Bumi paling dekat dengan Matahari (perihelion), suhu Bumi justru lebih rendah dibandingkan dengan saat jarak Bumi paling jauh dengan Matahari. Suhu Bumi sedikit lebih tinggi pada bulan Juli dikarenakan bagian utara planet Bumi yang padat akan daratan lebih condong ke arah Matahari, dimana daratan lebih cepat panas dibandingkan dengan lautan. Selain itu suhu di permukaan Bumi juga dipengaruhi oleh pola angin.

Abstract

Waktu salat Subuh dimulai ketika terbit fajar shadiq dan berakhir sampai terbit Matahari. Di Indonesia banyak ahli falak yang menetapkan kriteria ketinggian Matahari untuk menentukan awal waktu salat Subuh dengan ketinggian yang bervariatif, mulai dari -18 derajat sampai -20 derajat di bawah ufuk bahkan pada ketinggian -13 derajat di bawah ufuk. Kementerian Agama RI menetapkan ketinggian Matahari untuk waktu salat Subuh pada -20 derajat di bawah ufuk. Dengan adanya perbedaan dalam menetapkan ketinggian Matahari di bawah ufuk, para ahli falak maupun astronomi banyak melakukan pengamatan ulang terhadap kemunculan fajar shadiq. Salah satunya melakukan pengamatan fajar shadiq menggunakan All Sky Camera dengan metode moving average dan pendekatan Gradien. Penelitian ini merupakan penelitian kuantitatif dengan pendekatan (field Research) melalui observasi untuk mendapatkan data dilapangan secara langsung. Berdasarkan penelitian yang dilakukan didapatkan kemunculan fajar shadiq pada saat ketinggian Matahari pada -15 derajat di bawah ufuk.

Abstract

Teaching physics is sometimes difficult to convey without using props or visualizations. Simulations can help teachers create and demonstrate real conditions in front of the class. In this article, we describe the usage of spreadsheets in simulating Gibbs free energy in mixing polymer solutions. We have created an model for the simulation consisting of a main spreadsheet and several secondary spreadsheets. A spreadsheet was chosen to simulate Gibbs free energy because spreadsheets can perform numerical representations in tables. This simple simulation can be used when discussing the topic of polymer thermodynamics. Teachers can start by deriving mathematical equations and then show simulations to visualize the equations. Another option is for students to be asked to create their simulations after deriving a mathematical equation. Using simulation in learning can make learning more interactive and help students understand material physics subjects more easily. Spreadsheets can be an alternative for teachers when explaining abstract material to students. Furthermore, simulations with spreadsheets can also support physics learning remotely.

Abstract

The study investigated the relationship between the UV Index and measurements of ultraviolet A (UVA) and ultraviolet B (UVB) radiation to evaluate the effectiveness of the UV Index in predicting and understanding UV radiation at the surface. The implications of this study are significant for public health policies and UV protection strategies. This study used a variety of statistical analyses and modelling techniques, including ANOVA, Naive Bayes classification, decision trees, artificial neural networks, support vector machines (SVM), and k-means clustering, to examine relationships and predict UV Index values. ANOVA analysis showed a significant relationship between the UV Index and UVA and UVB measurements. Prediction models such as Naive Bayes classification, decision trees, and artificial neural networks showed variability in their accuracy. Notably, SVM showed a high degree of accuracy in predicting UV Index values, while k-means clustering effectively clustered the data based on similarities in UV Index and UV measurements. These findings confirm that the UV Index is a reliable indicator for predicting and understanding UV radiation levels at the Earth's surface. This research underscores the importance of developing more accurate and precise UV Index prediction models. Further investigation is essential to understand the temporal variations and environmental impacts on the UV Index, as well as the broader implications of UV exposure on public health. This study lays a strong foundation for the development of early warning systems and more effective UV protection strategies, ultimately improving public health outcomes and safety measures against UV radiation.
