Abstract

This study examines trends and variations in extreme temperature indices in Palembang for the period 1980-2020. They are using data from the Indonesian Agency for Meteorological, Climatological and Geophysics, namely the Palembang Climatology Station and the Sultan Mahmud Baharudin II Meteorological Station from the 1981-2020 period, which were analyzed according to the rules of the Expert Team for Climate Change Detection and Indices (ETCCDI). The results obtained based on the analysis showed that the average maximum temperature index (TMAXmean) and the minimum temperature average index (TMINmean) increased significantly with Z values ​​= 5.21 and 7.10. Based on the correlation analysis between time and extreme temperature index, it is possible to predict the occurrence of TMAXmean and TMINmean for the end of the 21st century, namely in 2100 with a value of TMAXmean = 36.1℃ and TMINmean 25.7℃. The TMAXmean event also has a very close correlation with the total area of ​​Forest and Land Fires, as well as the contribution of Greenhouse Gases ( ) in this region. So, it can be concluded that reducing the rate of increase in TMAXmean and TMINmean can be done by not burning forests and land so that the contribution of GHG ( ) to the atmosphere is reduced

Abstract

Synthetic anticancer agents have serious side effects on health. Therefore, it is necessary to develop natural anticancer agents with better effectiveness for cancer treatment. This study aims to determine the effect of exposure to ultrasonic waves on the extraction process by evaporation method on grain temperature, yield, and anthocyanin content of green betel and basil leaf. Exposure was carried out using 120 W ultrasonic waves for 0-30 minutes. The results showed that exposure for 30 minutes increased the temperature of the green betel leaf and basil leaves from 27oC to 52oC. Extraction by exposure to ultrasonic waves for 10 minutes obtained the highest yields of 13.87±1.10 % and 18.73±3.74% for green betel and basil leaf, respectively. Extraction with ultrasonic wave exposure time of 25 minutes resulted in the highest anthocyanin content, namely 490.10±6.67 mg/L and 242.65±9.09 mg/L for green betel and basil leaf, respectively. The high anthocyanin content is influenced by the exposure time and the temperature of the extracted granules. The time of exposure to ultrasonic waves of more than 25 minutes makes the grain temperature more than 50oC, so that the anthocyanin content of the extraction results decreases

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
