The methodology employed encompasses validity, reliability, and difficulty level analyses utilizing the statistical tool SPSS 25. The results of the validity analysis indicate that all items achieve a satisfactory level of validity based on the established evaluation criteria. Reliability testing also suggests a strong consistency of the test items used in the evaluation, ensuring measurement reliability. However, the evaluation highlights a discrepancy in the difficulty level of the items, where the initial classification of difficulty levels does not align with the analysis results from the processed data. Adjusting the classification of test items becomes crucial as it identifies a disparity in one of the items, which should be categorized as a difficult question, while previously classified as moderate. Meanwhile, the other test items align with the classifications previously determined by the researcher.</p> Indah Walfath Risa Faurenza Copyright (c) 2024 JEDMA Jurnal Edukasi Matematika 2024-01-31 2024-01-31 4 2 1 12 10.51836/jedma.v4i2.627 Analysis of Factors Affecting Labor Force Participation in Jambi Province Using Binary Logistic Regression Method http://ejournal.lppmstkippgri-sidoarjo.com/index.php/jedma/article/view/636 <p>National development is closely related to population issues in the field of labor that can increase the productivity of a country's economy. The Labor Force Participation Rate (TPAK) is one indicator of the success of economic development in a region. TPAK is an independent variable categorized as working and not working that is influenced by several independent variables. The TPAK category is included in qualitative data with a nominal data scale, the analysis process can use binary logistic regression analysis. Binary logistic regression is a statistical method that describes the relationship between an independent variable that has two or more categories and an independent variable that has a quantitative or qualitative scale. The model of this research conveys that the more the population in productive age works, the more influential it is on labor force participation. Then the marital status variable with the categories of marriage, divorce and death divorce plays a greater role in labor force participation than being unmarried. Furthermore, the variable of female gender has more labor force participation than male.</p> Agatha Febi Seventina Gusmi Kholijah Gusmanely Z Copyright (c) 2024 JEDMA Jurnal Edukasi Matematika 2024-01-31 2024-01-31 4 2 13 22 10.51836/jedma.v4i2.636 ANALISIS KEMAMPUAN PERBIKIR KRITIS MAHASISWA DALAM PENYELESAIAN SOAL SUBGRUP NORMAL http://ejournal.lppmstkippgri-sidoarjo.com/index.php/jedma/article/view/645 <p>Critical thinking is an important problem-solving skill because it enables individuals to critically analyze material, identify underlying assumptions, and make reasoned and informed decisions. According to various experts, critical thinking skills can be strengthened through learning, particularly mathematics learning for normal subgroups. As a result, This study is aimed&nbsp;to examine students' critical thinking skills for solving difficulties or problems of normal subgroups in order to gain an overview of students' critical thinking skills at high and low levels. The subjects of this study were mathematics education students from PGRI Adi Buana University, class of 2021, who were studying the algebraic structure 1, which focused on normal subgroup material. The results showed that high-ability students with a high level of critical thinking were able to perform at an evaluation level in problem solving. Low-ability students, on the other hand, only reached initial level while dealing with normal subgroup problems.</p> Liknin Nugraheni Copyright (c) 2024 JEDMA Jurnal Edukasi Matematika 2024-01-31 2024-01-31 4 2 23 29 10.51836/jedma.v4i2.645 KESALAHAN KONSEPTUAL DAN PROSEDURAL PESERTA DIDIK KELAS XI DALAM MENYELESAIKAN SOAL CERITA PADA MATERI PROGRAM LINIER http://ejournal.lppmstkippgri-sidoarjo.com/index.php/jedma/article/view/646 <p>The research aims to describe the results of the analysis of students' errors in solving linear program story problems. This type of research is called qualitative descriptive research. The determination of research subjects was taken from three students of SMA Al Kautsar Sukodono grade XI<em>,</em> who were given two linear program story test questions with moderate ability, had the aim of knowing the students' thinking, the types of errors made by students, and the internal factors that cause students to make mistakes. Based on the analysis that the researcher did, it was concluded that 1 subject did not make any conceptual or procedural mistakes, while the other 2 subjects made conceptual and procedural errors based on predetermined indicators based on intelligence weakness and inattentiveness in reading the information about the questions.</p> Wahyu Setiawan Intan Bigita Kusumawati Copyright (c) 2024 JEDMA Jurnal Edukasi Matematika 2024-01-31 2024-01-31 4 2 30 38 10.51836/jedma.v4i2.646 PENGEMBANGAN MOBILE LEARNING MATERI LINGKARAN BERBASIS ADOBE FLASH PROFESSIONAL CS6 http://ejournal.lppmstkippgri-sidoarjo.com/index.php/jedma/article/view/650 <p>Not all circular geometric objects are easy to present in class because they are large. Therefore, interactive learning media is needed to make it easier for students to learn circles, namely mobile learning based on Adobe Flash Professional CS6. This research aims to develop mobile learning circle material which is tested for its feasibility. This research includes development research with the ADDIE model (Analysis, Design, Development, Implementation and Evaluation). The resulting product is called CiFy (Circle Identify). The media was evaluated according to material and media experts and tested on 30 class VIII students at SMPN 1 Jabon. The assessment of the validity of the content of the material was rated at 3.27 and the media assessment was 3.46. Both material and media aspects are included in the valid category. The results of the practicality response questionnaire obtained a very positive response category and the assessment results from the validator stated that the media was suitable for use even though there were many revisions. The results of the effectiveness response questionnaire obtained a positive response category. From the learning result test score data, classical completeness data was obtained at 83.3%, which was included in the achieved category. Based on the results of these assessments, the learning media based on adobe flash professional CS 6 using mobile learning is declared appropriate for use as a learning material for circle material at Jabon 1 Junior High School.</p> Novi Puspita Ningrum Eka Nurmala Sari Agustina Lailatul Mubarokah Copyright (c) 2024 JEDMA Jurnal Edukasi Matematika 2024-01-31 2024-01-31 4 2 39 51 10.51836/jedma.v4i2.650
