The purpose of this study was to determine the effect of self-confidence on mathematical creativity. This type of research is quantitative research. Through the use of random sampling techniques, the sample for this study was 65 semester 1 student in the mathematics education study program at the Islamic University of Malang. The data collected in this study is the result of a questionnaire about students' self-confidence and mathematical creativity. The questionnaire used in this study has met the validity and reliability. Questionnaire results were analyzed by correlation test and linear regression test. Correlation and linear regression tests were carried out with the help of SPSS. The results of the research show that there is a correlation between self-confidence and mathematical creativity. The results also show that self-confidence has a positive effect on mathematical creativity by 32.5%. This influence is due to four things, namely self-confidence in solving math problems (even though it is difficult), confidence in expressing opinions during discussions, confidence when appearing in front of the class, and confidence when answering questions from the teacher. Thus, it is important to train students to be more confident in solving math problems, so that this will increase their creativity in solving math problems.</p> 2023-10-21T00:00:00+07:00 Copyright (c) 2023 https://proceedings.ums.ac.id/index.php/icomer/article/view/3159 Can Problem Based Learning Models Improve Students' Mathematical Problem-Solving Ability? 2023-10-23T08:00:02+07:00 Fajriani Asdar stfatimahyusuf07@gmail.com St. Fatimah Yusuf andi.fajriani99@gmail.com Nirwan Arif Indah Wijaya nirwanarief11@gmail.com Sriyanti Mustafa sriyanti_mustafa@yahoo.co.id <p>This research was motivated by the low problem-solving abilities of students, especially on the indicators of understanding the problem and checking back on the answers obtained. This research is classroom action research, which aims to improve students' mathematical problem-solving abilities through the Problem Based learning model. The subjects of this research were 35 students in class X 4 of SMAN 1 Sinjai, SMP Negeri 1 Patampanua class VII.5, totaling 26 people, and SMP Negeri 1 Mattirosompe class VIII.1, totaling 22 people. This research was carried out in two cycles. The research work procedure for each cycle takes place in four stages, namely: (1) planning, (2) implementing actions, (3) observing, and (4) reflecting. Data collection was carried out by giving problem solving tests to students. The data was analyzed using quantitative and qualitative analysis. Based on the results of the research and discussion, it can be concluded that the application of the Problem Based Learning learning model in two different phases in three schools can improve students' mathematical problem-solving abilities. After carrying out 2 learning cycles using Problem learning, it was found that the level of mathematical problem-solving ability for each indicator met the minimum criteria of 65%, and students' classical problem-solving completeness reached 100%.</p> 2023-10-21T00:00:00+07:00 Copyright (c) 2023 https://proceedings.ums.ac.id/index.php/icomer/article/view/3160 Implementation of Differentiated Learning Process Based on Students' Initial Mathematics Ability 2023-10-23T08:03:17+07:00 Danial Fanzeka fanzeka23@gmail.com Sultoni Sukri Subakti sukrisultoni@gmail.com Fandy Anugrah fandyanugrah13@gmail.com Sriyanti Mustafa sriyanti_mustafa@yahoo.co.id <p>This study was motivated by the low learning outcomes of students in learning mathematics caused by the diverse characters of students, especially in the aspect of students' initial mathematical abilities. This study aims to improve students' learning outcomes in learning mathematics by using process differentiation based on students' initial abilities. The method used in this research is classroom action research (CAR). The research procedure followed the Kemmis &amp; Taggart model, namely planning, action, observation, and reflection which was carried out in 2 cycles. The research subjects were students of class VIII.1 SMP Negeri 29 Bulukumba totaling 21 people, students of class VIII.1 SMP Negeri 10 Parepare totaling 32 people and students of class VIII.5 SMP Negeri 1 Mattiro Bulu totaling 26 people. The collection technique in this study was done through a learning outcome test. The results of research using process differentiation based on the initial ability of students showed an increase in learning outcomes. Based on the results of the research obtained the results of the actions provided, namely in cycle I students experienced an increase in learning outcomes compared to pre-cycle learning outcomes. However, because it has not met the standard of success, namely classical completeness reaching 85% of the students present, the provision of action is continued in cycle II. Then in cycle II students again experienced an increase in learning outcomes from cycle I and had achieved completeness of more than 85% of the students present. Based on the results of the research and discussion, it can be concluded that the application of differentiated learning process based on the initial mathematics ability of students carried out in the even semester of the 2022/2023 school year in three different schools located in South Sulawesi, namely SMP Negeri 29 Bulukumba (subject A), SMP Negeri 10 Parepare (subject B) and SMP Negeri 1 Mattiro Bulu (subject C) can improve students' mathematics learning outcomes.</p> 2023-10-21T00:00:00+07:00 Copyright (c) 2023 https://proceedings.ums.ac.id/index.php/icomer/article/view/3471 Contextual-Based 3D Animation Video With Book Creator on Set Materials 2024-01-08T13:17:22+07:00 Diyah Nur Ummah diyahnur103@gmail.com Fertilia Ikashaum ikashaum@gmail.com Venda Mega Faniya vendamega5@gmail.com <p>The research on the development of contextual-based 3D animation videos with a book creator is motivated by the use of school facilities such as projectors and computer laboratories that have not been used optimally.

Confidential digital data can be secured by encryption methods, one of which is the chaos function. We propose in this paper a new chaos function which is a composition of MS Map and Circle Map functions. This function has chaotic nature and is named the MS Circle Map. The sensitivity and randomness tests of the MS Circle map function are carried out using a bifurcation diagram, Lyapunov Exponent, and NIST. The analysis result of the bifurcation diagram shows that the MS Circle map has a good density at the value of r E (0,4). Besides that, the Lyapunov Exponent has a non-negative value at r E [0.4, 4], X0 = 0.9, r = 3.8, W = 0.5 λ = 2.1 which is the domain Xn E (0, 1) and parameter values r, E, and Ω, K are any real numbers. The results of the NIST randomness level test show that the MSC Map function all passed the randomness test of 16 NIST tests.</p> 2023-10-21T00:00:00+07:00 Copyright (c) 2024 https://proceedings.ums.ac.id/index.php/icomer/article/view/3473 Development Mathematics Test Based on Education for Sustainble Development to Measure Middle School Students' Creative Thinking Skills 2024-01-08T13:41:17+07:00 Indah Widiati indahwidiatimtk@edu.uir.ac.id Sari Herlina indahwidiatimtk@edu.uir.ac.id Ely Zahara indahwidiatimtk@edu.uir.ac.id <p>The design of ESD-based math problems to measure creative thinking skills namely contains indicators of creative thinking skills and is applied in everyday life day. The research design used is formative evaluation (self-evaluation, expert reviews, one-to-one, small group, and field tests). The research results show that from the initial design of the questions (47 students), only 28 questions were valid. After conducting large-scale tests shows that only some students can complete it. It is supported by the results of the written interview which said that the question was a moderate level of difficulty. But there are also those who say that the problem is too easy. With the research results is expected to produce guidelines in designing math-based test questions ESD for students.</p> 2023-10-21T00:00:00+07:00 Copyright (c) 2024
