Abstract

One of the materials studied by physics education students at the University of Jember in the agrophysics course is material about ionizing and non-ionizing radiation. Understanding the material requires the ability to think critically. With critical thinking, students' understanding can be said to be good on ionizing and non-ionizing radiation material. In this study using descriptive research methods with a quantitative approach. The purpose of using this method is to describe the understanding of physics education students in understanding ionizing radiation material (ionizing) type of gamma rays on food preservation. Respondents in this study were physics education students at the University of Jember totaling 50 students. Data were collected by distributing questionnaires. Based on the results of the analysis of the answers obtained from the Physics Education students of Jember University on the questionnaire regarding the understanding of gamma-ray irradiation techniques in food preservation, it can be concluded that the understanding of the concept of students is quite good. Students who are prospective physics teachers must have an understanding of the concept of physics. To improve understanding, it is necessary to have a good discussion and argue logically to train critical thinking.

Abstract

The electromagnetic wave spectrum includes extremely low frequency (ELF) magnetic fields, which have a frequency below 300 Hz and are considered non-radiation radiation. This research examines the effect of ELF magnetic fields on the physical condition of white sticky rice tape food, a traditional fermented food in Indonesia. The research is an experimental study that evaluates the physical condition of food ingredients. The research divides the materials into two groups: the control group, which is not exposed to magnetic fields, and the experimental group, which is exposed to magnetic fields with an intensity of 500 µT. The research uses 20 packs of each ingredient, with 10 packs in each group and 100 gr in each pack. The research tests four modules: login page, teacher’s profile update, image upload, and question creation. The research finds that exposure to an ELF magnetic field affects the aroma and texture of food ingredients. Exposure to ELF magnetic fields can speed up the growth of microorganisms. The research observes that the white sticky rice tape in the experimental group has a softer texture than the control group.

Abstract

This study explores the novel effect of an Extremely Low Frequency (ELF) magnetic field on the durability of glutinous tape food, a traditional Indonesian food made from fermented glutinous rice. ELF magnetic field is a spectrum of electromagnetic waves with frequencies less than 300 Hz that can influence microbial activity and the chemical changes in food. The study uses a unique experimental method that exposes 20 glutinous tape samples, divided into a control group and an experimental group, each with 10 samples, to an ELF magnetic field of 1,000μT intensity for 45 minutes. The study uses a Complete Randomized Design (RAL) and analyzes the data using the One Way Anova test with LSD and Kruskal-Wallis tests using IBM SPSS Statistics 23. The results show that the experimental group’s glutinous tape samples did not experience spoilage compared to the control group’s. The study proves the ELF magnetic field's effect on the durability of glutinous tape food and provides insights for developing new food preservation techniques. The study demonstrates the innovation and applicability of using the ELF magnetic field for food durability.

Abstract

Deuterium is one of the isotopes of the hydrogen atom, which consists of 1 proton, 1 neutron, and 1 electron, also called a hydrogenic atom. The position of electrons in the atom cannot be determined with certainty because it is probabilistic. The probability of finding a deuterium atom electron in momentum space at quantum number n 3. This research aims to find the probability value of deuterium atomic electrons in momentum space at n 3. This research uses the mathematical theory study method through several stages, namely collecting the latest and relevant literature sources, making a simulation program, and then validating the simulation program with existing theory. If it has been validated, continue taking data that will be analyzed and then discussed in the results and discussion stage, and the last step is drawing conclusions. The results of this study show that the probability value for finding atomic electrons in momentum space will be more excellent with increasing integration limit values and the value of the principal quantum number (n).

Abstract

This study explores the novel effect of Extremely Low Frequency (ELF) electromagnetic waves on the fermentation process of sticky rice tape, a traditional Indonesian food made from glutinous rice. ELF electromagnetic waves are waves consisting of magnetic fields and electric fields that do not require intermediaries in their propagation and have frequencies ranging from 0-300 Hz. The study uses a unique experimental method that exposes 2 kg of sticky rice tape, divided into 10 control and 10 experimental samples, each weighing 100 grams and wrapped in ziplock plastic, to ELF electromagnetic waves for two days. The study uses a device that generates ELF electromagnetic waves with a certain intensity and frequency. The study measures the changes in the pH, density, and taste of the sticky rice tape samples after the exposure. The results show that the experimental group’s sticky rice tape had a higher pH, higher density, and sweeter taste than the control group’s sticky rice tape. The study proves the effect of ELF electromagnetic waves on the fermentation process of sticky rice tape and provides insights for the development of new food processing techniques. The study demonstrates the applicability and innovation of using ELF electromagnetic waves for food fermentation.

Abstract

Gelombang elektromagnetik dengan frekuensi di bawah 300 Hz dikenal sebagai Medan Magnet ELF (Extremely Low Frequency). Penelitian ini bertujuan menganalisis dampak Medan Magnet ELF pada ketahanan tape ketan. Metode penelitian menggunakan eksperimen dengan desain RAL (Rancang Acak Lengkap), membagi kelompok eksperimen yang terpapar magnet intensitas 1.000μT selama 45 menit. Hasilnya menunjukkan bahwa tape ketan pada kelompok eksperimen memiliki pH rata-rata 3,65, massa jenis rata-rata 1,231, dan kondisi fisik normal, sedangkan kelompok kontrol dengan pH rata-rata 3,09, massa jenis rata-rata 1,271, dan kondisi fisik hampir tidak layak dikonsumsi. Kesimpulan penelitian ini adalah adanya pengaruh radiasi Medan Magnet ELF pada proses ketahanan tape ketan. Kata kunci: Gelombang elektromagnetik; medan magnet; tape ketan.

Abstract

Learning Props are teaching aids designed to accompany project-based learning activities. This community service is motivated by the problems faced by educators when implementing project-based learning models. Therefore an innovation is needed for these problems. SMP PGRI 1 Tempurejo is a target school in Jember district that is still less educated about the use of teaching aids in project-based learning models to support the implementation of an independent learning curriculum. This service activity is carried out in three stages, namely the preparation stage, the implementation stage, and the evaluation and reporting stage. The activities carried out in this community service are conducting training on the use of teaching aids media in project-based learning models to support the implementation of an independent learning curriculum for teachers and students at SMP PGRI 1 Tempurejo Jember. PhET media is an interactive simulation media that is given to students to facilitate practicum that cannot be done directly or real but uses a virtual laboratory that is effective in learning. In the training activities, teachers and students responded quite well, this was indicated by the response of teachers and students who stated that they knew about PhET media in the project-based learning model after conducting training. Based on the results, it can be concluded that the participants who took part in the training increased their insight, knowledge and skills about the use of teaching aids in the project-based learning model as a support for the implementation of an independent learning curriculum.
