Analisis Proses Literasi Matematis Peserta Didik Menurut Tingkatan Resiliensi Matematis
Get PDFThe aims of this research is to analyze students' mathematical literacy processes according to levels of mathematical resilience. This research is a qualitative descriptive study. Data collection techniques consisted of distributing mathematical resilience questionnaires, mathematical literacy tests and interviews. The research instruments used were a mathematical resilience questionnaire and mathematical literacy questions. The data analysis techniques used are data reduction, data presentation and drawing conclusions. The subjects of this research were three students in class VII-A of SMP Negeri 1 Bantarkalong from each category of high, medium and low mathematical resilience. The results of this research are that students with high resilience (S-11) go through the three mathematical literacy processes correctly. From each process that students go through, they are able to write down each step of completion in detail and systematically. Students with moderate resilience (S-10) go through the three mathematical literacy processes. From each process that is passed, there are students' answers that are still lacking in detail in their writing. Students with low resilience (S-18) went through the three processes but the answers they got were wrong. From each process they go through, students with low resilience do not write answers systematically and in detail and are still less careful in carrying out calculations
Kemampuan argumentasi matematis ditinjau dari adversity quotient
Get PDFThis study explores students' mathematical argumentation abilities in solving SPLTV (Three Variable Linear Equation System) problems, viewed through the lens of their Adversity Quotient (AQ). It employs a qualitative, exploratory approach, using non-test AQ questions, mathematical argumentation tests, and unstructured interviews for data collection. The subjects were 19 students from class X at SMA Negeri 1 Kedungreja, from which 5 students per AQ category with the highest scores were selected for interviews. Results indicate that students in the climbers, climbers-campers transition, campers, and campers-quitters transition categories met the data indicator by correctly completing mathematical models. In contrast, quitters failed to do so. For the claim indicator, climbers, climbers-campers transition, campers, and campers-quitters transition students successfully identified the methods used, while quitters did not understand the methods. Regarding evidence, climbers and climbers-campers transition students explained the steps correctly, whereas campers, campers-quitters transition, and quitters made calculation errors. Only climbers met the reasoning indicator by providing correct proofs, while others did not fully solve the problems. In the rebuttal indicator, only climbers accurately identified contradictions. The main issues hindering students' mathematical argumentation abilities include carelessness in calculations, lack of fundamental understanding of SPLTV concepts, and unfamiliarity with contextual questions

Komparasi Implementasi Partisipasi Perempuan dan Sistem Pemilu di Negara Indonesia dan Australia
Get PDFWomen's political participation and the electoral system are two key factors in strengthening democracy in each country. This study aims to investigate the extent to which political, cultural and structural factors influence women's political participation in the two countries. The presence of women in representative numbers in parliament will not only have an impact on political decisions relating to gender equality and justice, but will also be an indicator of improving the quality of democracy. The method applied in this research is a qualitative approach with literature study data collection techniques. The results of this study are that Indonesia and Australia still need serious attention to women's political representation. In Indonesia, although there are regulations that set quotas for women's representation in general elections, implementation is still not optimal, with a significant gap between targets and realization. Australia has made progress in women's representation in parliament, but there are still imbalances that need attention. Challenges include gender stereotypes, lack of support from political parties, and social issues such as "toxic masculinity" that affect perceptions of women's roles in politics
