Abstract

Extremely Low Frequency (ELF) electromagnetic waves are electromagnetic waves with a frequency range of 0 to 300 Hz. ELF electromagnetic wave radiation produces non-thermal effects on the biological objects used, meaning that it does not cause temperature changes when interacting with or inducing the system. Electromagnetic waves are waves that arise due to changes in electric fields and strong magnetic fields. This research aims to prove the effect of Extremely low frequency (ELF) magnetic field on the food resilience process. The research method used is experimental research method. This research was carried out in the basic physics laboratory at the University of Jember. Data collection techniques using observation. Based on the research, it can be concluded that ELF magnetic field radiation has the potential as an alternative method in increasing the nutritional value and durability of fermented food ingredients. Exposure to Extremely Low Frequency magnets with an intensity of 1000 μT for 45 minutes resulted in changes in pH value and physical quality that affect food durability in cassava tape.

Abstract

ABSTRACTExtremely Low Frequency (ELF) electromagnetic radiation is an electromagnetic wave that has a low frequency range, which is around 3Hz-300Hz. Gclumps at this frequency have a very long wavelength of about 100,000 to 10,000 km per wave. Tape is one example of a fermented product. Exposure to ELF electromagnetic radiation can affect the duration of food ripeness, one example is fermentation on tape. Fermentation on tape uses the help of yeast, which is a microorganism that reacts on a substance to produce a product. The research method  used was experimental research with exposure to a 500 μT ELF magnetic field  on samples for 60 minutes. Exposure to ELF waves affects the maturity process of cassava tape which can be proven by differences in taste, texture, and color.Keywords: electromagnetic ELF, wave, tape  ABSTRAKRadiasi elektromagnetik Extremely Low Frequency (ELF) adalah gelombang elektromagnetik yang memiliki rentang frekuensi yang rendah, yaitu sekitar 3Hz-300Hz. Gelombang pada frekuensi ini memiliki panjang gelombang yang sangat panjang yaitu sekitar 100.000 hingga 10.000 km setiap gelombangnya. Tape adalah salah satu contoh produk hasil fermentasi. Pemaparan radiasi elektromagnetik ELF dapat berpengaruh pada durasi kematangan bahan pangan, salah satu contohnya yaitu fermentasi pada tape. Fermentasi pada tape menggunakan bantuan ragi, yang mana merupakan mikroorganisme yang bereaksi pada suatu zat sehingga menghasilkan produk. Metode penelitian yang digunakan adalah penelitian eksperimen dengan paparan medan magnet ELF 500 μT pada sampel selama 60 menit. Paparan gelombang ELF berpengaruh pada proses kematangan tape singkong yang dapat dibuktikan dengan perbedaan rasa, tekstur, dan warna.Kata kunci : elektromagnetik ELF, gelombang, tape

Abstract

This research aims to determine the effect of a blended learning model based on the application of Nearpod on students' interest and learning outcomes in physics at one of the secondary schools in Jember. This research is a type of experimental research that uses a post-test only control group design. The population of this study were students of class XI MIPA and XI BIC. Sampling used a random sampling technique, so that XI BIC 2 students were obtained as a control group implementing the conventional learning model and XI MIPA 1 as an experimental group implementing blended learning based on the Nearpod application. The instrument used is a physics student interest questionnaire which consists of 4 indicators and a post test in the form of a multiple-choice test which refers to students' cognitive abilities to remember (C1), understand (C2), apply (C3), analyze (C4), evaluate (C5), and create (C6). Questionnaire data and post test data regarding the influence of blended learning based on the Nearpod application on students' interest in learning and physics learning outcomes will be tested for homogeneity. If a significance value >0.05 is obtained, questionnaire and post test data for the control class and experimental class were normally distributed. Interest data and physics learning outcomes were analyzed using parametric statistics, namely the Independent Sample T-test. Based on the hypothesis testing criteria, H0 is rejected (Ha is accepted) if the sig value is <0.05, meaning that there is an influence of the Nearpod application-based blended learning model on student physics interest. Meanwhile, in the physics learning outcome test, students got the sig value of <0.05, which means that Ha is accepted, meaning that there is an influence of the Nearpod-based blended learning model on student physics learning outcomes. The application of the blended learning model based on the Nearpod application has a significant effect on students' interest and learning outcomes in physics.
