Abstract

This study explores the novel effect of Extremely Low Frequency (ELF) magnetic field radiation on the ripening process of raw fermented tempe, a traditional Indonesian food made from soybeans. ELF magnetic fields are environmental factors that can influence the growth of microorganism activity. The study uses a unique laboratory experimental method that employs a Current Transformer (CT) device to produce an ELF magnetic field with an intensity of 500miu, which is a relatively high intensity compared to the natural background level of ELF magnetic field. The study examines 20 raw tempe samples, each weighing 100g, divided into two groups: a control group and an experimental group. The experimental group is exposed to the ELF magnetic field for 24 hours, while the control group is not. The study measures the changes in the microbial population, pH, moisture content, and sensory quality of the tempe samples after the exposure. The study aims to prove the effect of ELF magnetic field radiation on food security and to provide insights for the development of new food preservation techniques.

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

The discovery learning model, combined with the Vee map learning approach, has been found to be suboptimal in previous studies for enhancing inference skills and physics learning outcomes. This research is needed to investigate the effect of the discovery learning model, assisted by Vee Map, on the inference skills and physics learning outcomes of high school students in the context of alternating current material. Employing an experimental method with a posttest-only control group design, the study randomly selected a sample, assuming a homogeneous population. The population for this study was drawn from SMA Negeri Ambulu's Class XII. The sample was chosen randomly (cluster random sampling) under the premise of demographic homogeneity, yielding two classes: XII Science and Technology 1 as the experimental class and XII Science and Technology 2 as the control class. Data were gathered through posttests of inference skills and physics learning outcomes in experimental and control classes using alternating current material. Independent sample t-tests revealed a significant effect: inference skills showed a significance of 0.006 < 0.05, and physics learning outcomes had a significance of 0.000 < 0.05. These results validate the alternative hypothesis (H????), confirming a notable difference in students' inference skills between the control and experimental groups, and refute the null hypothesis (H0), which posited no significant difference. Consequently, this study concludes that the discovery learning model, as facilitated by the Vee Map, improves high school students' inference skills and physics learning outcomes in the subject of alternating current.

Abstract

Students often have difficulty understanding complex and abstract thermodynamic concepts, due to differences in learning styles, low digital literacy, and lack of effective media and learning methods. This study aims to identify the causes of these difficulties, determine the most difficult concepts to understand, and formulate appropriate learning strategies to improve student understanding. The research method used is a descriptive quantitative method that is able to provide an objective picture of the students' level of understanding, the various difficulties they experience, and the aspects that affect their learning process. From this research, the results and conclusions were obtained that students tend to have difficulty in understanding abstract concepts of thermodynamics due to ineffective teaching methods and weak basic understanding so that innovative learning strategies that integrate theory and practice are needed to improve understanding

Abstract

The prevailing pedagogical approach in class X SMA entails the utilization of questions from LKS or books, thereby engendering suboptimal student engagement and learning outcomes in physics.This study posits the necessity for pedagogues to enhance their lesson planning and media utilization in the classroom, with the objective of facilitating innovative Problem Based Learning (PBL) models accompanied by crossword puzzles.The present study aims to elucidate the enhancement of activity and learning outcomes of X grade high school students through the implementation of the PBL model accompanied by crossword puzzle media. The subject of this research is class X 2 SMAN 5 Jember.This research employed a Classroom Action Research approach, which was conducted in two cycles, each comprising four stages: planning, implementation, observation, and reflection.The results of the first cycle were used as a reference for the implementation of the second cycle, with improvements made to address the weaknesses identified in the first cycle. The findings of this study revealed that the implementation of the PBL model, coupled with the incorporation of a crossword puzzle, resulted in a 0.60 increase in student learning outcomes in cycle 1. Subsequent to cycle 2, there was an augmentation in the average student learning outcomes to 0.76 Furthermore, the analysis of learning activities in cycle 1 revealed an active category, while cycle 2 exhibited an increase, including an increase in the very active category. Consequently, it can be deduced that the implementation of the PBL model, integrated with a crossword puzzle, has led to a twofold enhancement in the activity and learning outcomes of physics students at SMAN 5 Jember.
