https://jurnal.unimor.ac.id/index.php/JPM/article/view/5674
<p><em>This research aims to examine the significant factors influencing economic growth in the East Nusa Tenggara Province. The estimation is carried out through a spatial regression model approach. The research variables were selected based on the economic growth model proposed by Mankiw-Romer-Weil, namely Gross Regional Domestic Product at constant prices (Y), </em><em>Labor</em><em> (</em> X1<em>), Electricity Consumption (X2</em> <em>), Regional Original Income (X3</em> <em>), </em><em>Capital Expenditure</em><em> (</em> X4<em>), and Schooling Duration (X5</em> <em>). The research data consists of secondary data from the year 2022 in 22 regencies/cities obtained from the Central Statistics Agency (BPS) of East Nusa Tenggara Province. Modeling with the Ordinary Least Squares (OLS) regression method resulted in three significant independent variables at α=5%: local revenue, capital expenditure, and average years of schooling. Based on diagnostic tests, there was spatial dependence in lag and error, leading to the use of Spatial Autoregressive Model (SAR) and Spatial Error Model (SEM) for spatial regression. From these spatial models, the significant independent variables influencing economic growth in the 22 regencies/cities in East Nusa Tenggara were local revenue, capital expenditure, and average years of schooling. The queen contiguity weighting was used. Based on R</em><em><sup>2</sup></em><em> and AIC criteria, the best spatial regression model was the Spatial Error Model (SEM) with the highest R</em><em><sup>2</sup></em><em> of 0.837610 and the smallest AIC value of 393.03. For further research, it is recommended to consider local factors that may influence economic growth, such as the sustainability of the agricultural or tourism sector, which may vary in each region.</em></p>Elisabeth Brielin SinuAstri AttiArista Marlince TamonobDamaris Lalang

https://jurnal.unimor.ac.id/index.php/JPM/article/view/5612
<p><em>Learning using the 2013 curriculum encourages students to have 4C abilities. The findings of the initial test results in class IX of SMP Negeri 3 Muntilan, their critical thinking skills were classified as poor. Mathematical disposition abilities influence the low and high level of students' mathematical critical thinking abilities. The findings from the initial questionnaire showed that mathematical disposition ability was in the medium category. Then, with the need for students not to get bored quickly and to be active when learning, the Problem Based Learning (PBL) model assisted by math cards was implemented. The research objective to be achieved in this study is to analyze in a multivariate way the critical thinking abilities and mathematical disposition abilities taught using the PBL model assisted by mathcards are better than those taught using the expository learning model on quadratic equations. The approach used is quantitative research with a quasi experimental design in the form of a non equivalent posttest only control group design. The results of this research are; Multivariately, students' critical thinking abilities and mathematical disposition are better in the PBL model assisted by mathcards compared to the expository model in quadratic equations. However, educators need to reconsider the material that will be applied with this mathcard-assisted PBL model, because this model is not necessarily suitable for all material.</em></p>Firda Nur ArifaSyita Fatih ‘AdnaAprilia Nurul Chasanah

https://jurnal.unimor.ac.id/index.php/JPM/article/view/5624
<p class="E-JournalAbstractBodyIndo"><span lang="IN">This research aims to design Student Worksheets (LKM) for the Discrete Mathematics course, where the LKM design is structured so that the LKM can be used in the Rigorous Teaching and Learning (RTL) learning model. The results of the lecturers' reflections found that the main problem lies in the content of the material in textbooks which is not interesting, students are often unable to understand the textbooks they own, especially in solving the questions given. This has implications for 1) lack of motivation to learn, 2) lack of understanding of the material, 3) fear of expressing opinions, and 4) lectures are less effective and less enjoyable. Therefore, teaching materials need to be packaged appropriately according to the substance and conditions of students in LKM. The research design used in this research is Thiagarajan's 4-D development model. This model is a system of educational development approaches that are carried out in 4 sessions, namely Define or Introduction where in this session preliminary analysis, student analysis, and needs analysis are carried out, Design or Planning where in this session what is done is format selection, initial design and design preparation, Develop or Development where in this session validation and limited trials are carried out, as well as Disseminate or Disseminate where in this session the LKM is given to the teaching lecturers. This research produces an LKM that is used in Discrete Mathematics courses.</span></p>Ade MirzaRevi Lestari PasaribuJustin Eduardo Simarmata

https://jurnal.unimor.ac.id/index.php/JPM/article/view/6844
<p>This study aims to compare the effectiveness of learning using Contextual Teaching and Learning (CTL) and the Missouri Mathematics Project (MMP) in terms of students' mathematics learning outcomes. The research method employed was an experiment with a pretest-posttest non-equivalent comparison-group design. The research population consisted of seventh-grade students, with the sample being students from class VII A using the CTL learning model and class VII B using the MMP learning model. The independent variable in this study is the learning model, while the dependent variable is the mathematics learning outcomes. The instruments used were a learning outcome test and an observation sheet for the implementation of learning. The results of the study indicate that both learning models, CTL and MMP, are effective in improving students' mathematics learning outcomes. The Wilcoxon test analysis showed that the significance values for both models were less than 0.05, indicating their effectiveness. However, the Mann-Whitney test revealed no significant difference in effectiveness between the two learning models. These findings suggest that both CTL and MMP can be used as effective alternative teaching methods to enhance students' mathematics learning outcomes. This study contributes to the selection of appropriate teaching methods to improve understanding and learning outcomes in mathematics. It is recommended for future researchers to investigate other aspects such as cognitive, psychomotor, or affective domains, and for teachers to consider using CTL and MMP in their teaching activities.</p>Yosepha P.

https://jurnal.unimor.ac.id/index.php/JPM/article/view/7178
<p><em>Weibull distribution is one of the continous probability density function. This distribution is known as a flexible distribution. One of it’s flexibility is can be transformed into other distributions such as exponential distribution depends on parameter selected. Similar to other distribution, Weibull distribution also characterized by cumulative distribution function, mean, variance and moment generating function. One of the well-known application of this distribution is in the field of quality control utilizing reliability data and the well-known tool in quality control is control chart. Therefore, reliability data is not follow normal distribution then Shewhart control chart cannot be applied. To solve this problem, control chart can be formed with the control limit is obtained by Bayesian method. In applying Bayesian method, prior distribution of shape parameter is assumed to be uniform distribution and variables for reliability is assumed to be invers of Weibull distribution. The prior distribution is combine with likelihood function then posterior distribution is obtained which in then used as the control limits by find it’s mean.</em></p>Cecilia Novianti SalsinhaYeni Rafita SihombingMelissa Aeudia Daullu
