Abstract

The purpose of the literature review in this study was to thoroughly evaluate and assess the theories, signs, effects, and initiatives used to help students overcome their math anxieties. The type of research used is a literature study. This study used the systematic literature review (SLR) method. The data collection technique used is the inclusion criterion, and the data analysis technique used is exposition. Based on the findings of several studies, it is clear that mathematical anxiety negatively impacts students' learning outcomes, learning processes, and mathematical abilities, including their ability to solve math problems and other mathematical abilities. Of course, based on these studies, there is a need for efforts to overcome mathematics anxiety, both carried out by teachers and students so that the mathematics learning process can run smoothly. But not all math anxieties produce negativity. Some articles also mention that math anxiety can improve students' mathematical achievement.

Abstract

The system of linear equations of two variables is contextual material in learning mathematics. Yet, there are facts that show there are still errors and difficulties experienced by students in the problem of the system of linear equations of two variables. The research purpose is to conduct a literature review on the skills, errors, and difficulties of students on the problem of the system of linear equations of two variables. This research uses the SLR (Systematic Literature Review) method. Data collection was carried out by reviewing all articles related to math skills, errors, and difficulties of students on the problem of the system of linear equations of two variables published from 2019 to 2023. Based on the research results, it was found that students' skills to solve the problem of two-variable linear equation system was still low. Students still made many mistakes in understanding the problem and converting it into a mathematical model, carrying out the plan or process, performing calculations, and often ignoring the evaluation of the results obtained.

Abstract

This research was conducted to learn about implementing the problem-based learning model to improve critical thinking in physical education. This research study aims to analyze the impact of using problem-based learning on increasing critical thinking in physical education and its influence on the 21st century. The research method used is the Systematic Literature Review research method using a qualitative approach. The data collection used was by collecting other literature studies resulting from research in 18 examinations taken from 7 sources, which were included in a systematic review based on the quality of the sources. The results show that problem-based learning can be a practical approach for improving students' critical thinking skills. In conclusion, problem-based learning can enhance students' learning experiences, encourage critical thinking, and increase deeper understanding of concepts and facts.

Abstract

Dengue merupakan penyakit menular yang masih menjadi masalah kesehatan di dunia. Manifestasi klinis infeksi dengue sulit dibedakan dengan penyakit infeksi lainnya. Uji diagnostik infeksi virus dengue yang cepat dan akurat sangat diperlukan untuk konfirmasi penyakit dan penanganan pasien yang tepat. NS1 adalah glikoprotein yang paling imunogenik dan lestari, disekresikan ke dalam aliran darah. Oleh karena itu, pemeriksaan antigen dari virus dengue NS1 telah diidentifikasi sebagai salah satu penanda spesifik dalam uji diagnostik laboratorium, yang dapat digunakan untuk mendeteksi infeksi dengue primer atau sekunder pada stadium awal. Penelitian ini bertujuan untuk menentukan kondisi optimum ekspresi protein fusi scFv-BAD rekombinan untuk deteksi antigen NS1 virus dengue menggunakan Response Surface Method. Ekspresi protein diinduksi oleh berbagai konsentrasi IPTG (0,1, 0,5, dan 1 mM) pada beberapa suhu selama 18 jam dalam medium Luria Bertani dengan penambahan biotin. ScFv terbiotinilasi rekombinan yang dimurnikan dikarakterisasi dengan metode SDS-PAGE. Hasil penelitian menunjukkan bahwa protein fusi scFv-BAD rekombinan sebagian berada dalam bentuk terlarut dan sebagian berupa badan inklusi. Analisis Central Composite Design menunjukkan bahwa konsentrasi IPTG yang sesuai untuk memproduksi protein scFv rekombinan adalah 0,5 mM pada suhu 28 ºC pada media Luria Bertani.

Abstract

This study reveals how prospective teacher students solve Integral Calculus problems with three different assistances, namely the Assistance of Lecturer Tutors, Google Search Tutors, and Artificial Intelligent (AI) Tutors through Socratic Application. This study used a qualitative approach with phenomenological methods to reveal participants' learning experiences. Research participants consisted of nine people who were divided into three groups with different assistance. The data obtained were in the form of recorded discussions, interviews, recorded cellphone screens, and artifacts of student answers. All data is analyzed based on the activity of the respondents in seeking and finding answers. The research findings show that students who study with the help of lecturer tutors are more careful in proposing assistance from the search and sorting of answers stage. While students who use AI and Google Search have almost the same characteristics in starting a search, but at the stage of sorting answers,  AI is thought as able to provide more efficient and accurate recommendations answers.

Abstract

This study aims to explore the misconceptions that occur in group theory learning conducted by pre-service mathematic teachers.  This research is part of a long research from abstraction in learning group theory: study of hermeneutic phenomenology on pre-service mathematics teachers.  This research method uses case study in qualitative research.  Data obtained in the form of Focus Group Discussion (FGD) videos and pdf files of partisipan diaries.  The findings of this study indicate a misconception on group as set and subset as subgroup and on the inverse element as only one over in multiplication.  These two misconceptions show from misunderstanding and misperseption.

Abstract

This study aims to optimize the epithelial sodium channel (ENaC) electrochemical aptasensor with the Box-Behnken experimental design. ENaC is a protein that plays a role in sodium ion transport in several epithelial tissues and is associated with hypertension. The ENaC protein aptamer is held in place in the electrochemical aptasensor by a modified screen-printed carbon electrode (SPCE) of silica-ceria composite (SiO2-CeO2). The unique structure of a silica matrix with high biocompatibility can form composites through a hydrothermal process. The Box-Behnken (BBD) experimental design is an efficient optimization method of factors that affect the experiment at three levels. The FTIR results of the silica-ceria composites were 549.35 cm-1 (Ce-O), 1095.3 cm-1 (Si-O-Si), and 491.28 cm-1 (Si-O). Meanwhile, SPCE/silica-ceria characterized by differential pulse voltammetry (DPV) showed an increase in peak current [Fe(CN)6]3-/4- from 3.190 μA to 9.073 μA. Three experimental factors, aptamer concentration, streptavidin incubation time, and aptamer incubation time, were optimized with BBD and obtained at 0.5 μg.mL-1, 30 minutes, and 1 hour. The optimum conditions observed resulted in a selective current response for ENaC protein detection. The optimization results can be applied to aptamer-based ENaC protein detection in samples.
