Abstract

The Covid-19 pandemic has caused changes in the world educational system. The pandemic caused a rapid transition from face-to-face lectures to online lectures. The times of the Covid-19 pandemic or what is often called “the New Normal", are still ongoing today. Online lectures are expected not to reduce the Program Studi’s Graduate Learning Outcomes (GLO) of a course or not to reduce competencies that must be mastered by students. Lecturers as course supervisors must try to facilitate the student learning process with valid, and easy-to-use teaching materials. To meet the needs of these students, first, we must know the student's responses to the teaching materials, so that it can facilitate independent learning in students during these pandemic times. This research is developmental research that aims to produce digital handouts that can be accessed via cellphones or laptops and can be accessed both online and offline situations. The development model chosen in this research is the Rowntree model with Tessmer formative evaluation. The data was obtained through online questionnaires created in the google form and given to lecturers or students. The results showed that 100% of students had difficulties in learning nuclear physics introduction materials independently and 86% of them requested that the teaching materials should be provided with pictures, animations, and videos. Based on the needs analysis above, we develop a valid and practical STEM-based digital handout teaching materials about nuclear physics introduction

Abstract

This study aims to identify the misconception in the students as well as the teachers on the same topic, namely Energy. This study used mixed-method research of sequential exploratory type with the research subjects of the teachers and the students in North Central Timor Regency with a sample size of 163 students and 12 physics teachers. The misconception data was obtained by giving a misconception test in the form of a multiple-choice question. There were 12 questions with 5 answer choices which were equipped with CRI (Certainty of Response Index). The results showed that the percentage of students' misconceptions for the whole question (12 items) was quite large, namely 43.66%, while students who had a good understanding of the concept were 38.80%. Nearly 18% of students did not understand the concept while 4.24% were just guessing and lucky (Lucky Guess) while the remaining 13.29% were the total students who did not understand the concept of the questions at all. Meanwhile, of the teachers, an average of 77.08% have mastered the concept of Energy. However, as many as 22.92% of the teachers had the misconception on several questions, namely (question number 5,6,7,8,9,10, and 12) with the most misconceptions on question number 7, 10, and 5. The conclusion obtained was that the misconception found in physics teachers was 22.92%. For the students, there was still a large portion of them who had misconceptions about the topic of Energy. This was caused by the lack of students' understanding of the topic of Energy

Abstract

Electrosurgery Unit (ESU) is a medical surgical device that uses high frequency and high voltage with the aim that the patient does not experience excessive bleeding during the operation process. The development of electrosurgery unit technology evolves over time from monopolar to bipolar. However, in the development of the use of the tool, monopolar technology is always the most widely used in tissue surgery techniques. For this reason, this research was determined to use only the Monopolar principle. In Electrosurgery, the actual unit only uses one frequency selection, by changing (increasing or decreasing) the power value. With cases like this sometimes the user or equipment users will always change the power value during operation to determine the right power value. In this case, the author tries to make a prototype of an electrosurgery device with a frequency that can be selected (300, 350, 400, 450, 500, 550, 600 and 650 KHz) with a fixed power. By examining the results of the effectiveness of cutting (CUT) on tissue samples. It is hoped that it will be known which one is faster and more effective which can be used in cutting techniques (CUT) in surgery
