The aim of this study is to investigate the misanalogical construction of undergraduate students in their cognitive conflict in doing a non-routine mathematical task. Qualitative methods were used in this research. Data were collected from 68 seventh semester undergraduate students of Mathematics Education Study Program, Universitas Negeri Malang by assigning them to accomplish the cognitive conflict identification task and interviewing them. It is found that five students have experience the autocognitive conflict. So that we made an indepth interview to these five students to trace the misanalogical construction in their cognitive conflict and found that one of them made the misanalogical construction, and she was Elsa. The investigation result from Elsa shows that she made several misanalogical construstions in her cognitive conflict in solving the task. They are misanalogical construction in set theory, misanalogical construction in fraction, and misanalogical construction in sequence.

The purpose of this study was to analyze the interest in learning mathematics of twenty English education students at a university in West Papua. This research method is a qualitative research method using descriptive techniques. The procedure of this research starts from the development of the questionnaire instrument, the development of the interview instrument, the validation of the instrument, the distribution of the questionnaire, the determination of the subject, and the interview. Based on the results of data analysis, it is known that the interest in learning mathematics of English education students based on indicators of student interest in learning mathematics is categorized into three groups, namely students who are not interested in learning mathematics, quite interested in learning mathematics, and interested in learning mathematics. Students in the category of the uninterested group have not been able to meet the indicators of interest in learning mathematics. Meanwhile, students in the moderately interested groups can fulfill three indicators of interest in learning mathematics: students' feelings of pleasure in mathematics, students' interest in mathematics, and students' attention to mathematics. Students from the interest group category can fulfill the four indicators of interest in learning mathematics: students' feelings of pleasure in mathematics, student interest in mathematics, student attention to mathematics, and student involvement in mathematics.

The purpose of this study is to find out what are the obstacles for mathematics educators in implementing distance learning during the COVID-19 pandemic. The method used in this study is a qualitative method using descriptive techniques. The research subjects in this study were mathematics educators at YAPIS Manokwari High School. Based on the results of the interview, the results of this study indicate that there are several obstacles in the implementation of distance learning. Constraints experienced in learning include human constraints where teachers are still not optimally using the applications used for the learning process. Some teachers are not proficient in using applications as a medium for learning.Abstrak: Tujuan penelitian ini adalah untuk mengetahui apa saja kendala pendidik matematika dalam melaksanakan pembelajaran jarak jauh dimasa pandemi COVID-19. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan menggunakan teknik deskriptif. Subjek penelitian pada penelitian ini adalah pendidik matematika di SMA YAPIS Manokwari. Berdasarkan hasil wawancara, hasil penelitian ini menunjukkan bahwa ada beberapa yang menjadi kendala dalam pelaksanaan pembelajaran jarak jauh. Kendala yang dialami dalam pembelajaran meliputi kendala manusiawi dimana guru masih belum secara maksimal menggunakan aplikasi yang digunakan untuk proses pembelajaran. Ada beberapa guru yang belum mahir dalam penggunaan aplikasi sebagai media untuk pembelajaran.

Students' ability for HOTS is critical to acquire. However, the PISA survey in 2018 showed that Indonesian participants were at level 1, and the national exam in 2018 indicated that 40% of students had an issue answering HOTS questions. The problem suggests that students solve questions requiring higher-order thinking skills, causing errors. Therefore, the study aimed to analyze student errors based on Newman's Theory in solving HOTS-based math story problems. The method applied for qualitative research with a descriptive approach. Data collection involved 126 grade IX students using HOTS-based math story tests, interviews, and documentation. Students were grouped into three categories from the HOTS-based math story test results: students with good, medium, and low abilities. This step was to find the average and standard deviation of the scores obtained by respondents when completing the given test. Then three students were selected from each category as subjects. The results showed that as many as 50% of students misunderstood the questions, 20% made transformation errors, and 10% errors in reading, processing skills, and encoding. The high error rate of these students shows the poor ability of students to solve HOTS-based math story problems.

<em>Stablility and equilibrium of malaria epidemics in the district of Manokwari Barat based on SIR epidemic model will be discussed in this paper. The SIR epidemic model can be applied to make a model of endemic diseases like malaria. Based on this research, there are two types of the equilibrium of malaria&rsquo;s epidemics in Manokwari Barat district which are endemic and non endemic points. </em>
