<![CDATA[CENS is a meteorological phenomenon in the form of surface wind flow originating from the South China Sea (SCS), very strongly across the equator. CENS is closely related to the increase in average rainfall in parts of Indonesia. There has been very heavy rainfall on January 18, 2022 in the Jakarta area which resulted in flooding. Therefore, this study focuses on seeing if there is a CENS relationship that is factor in increasing rainfall in the Jakarta area on January 18, 2022. The results showed that the NCS began to form on January 16-17, 2022 with a Siberian High of 1040.6 hPa and the propagation of cold air masses from Asia to the south which was an indicator of CENS. The next day, the CENS phenomenon began to occur, characterized by meridional wind speeds in the 105˚- 115˚BT region of less than -5 m/s. This phenomenon triggers the strengthening of the northeast Asian monsoon flow so that the area south of the equator, including Jakarta, gets a large moisture transport from the SCS. This causes the potential for the formation of high convective clouds to trigger very heavy rain and cause flooding in the Jakarta area on January 18, 2022.]]>

<![CDATA[The background of this study is the lack of mathematical disposition of students and different genders towards the numerical abilities of class X students of SMAN 1 Bae Kudus. This study aims to (1) determine the influence of mathematical disposition on the numerical abilities of class X students of SMAN 1 Bae Kudus; (2) knowing the influence of gender on the numerical ability of class X students of SMAN 1 Bae Kudus; (3) knowing the influence of mathematical and gender dispositions together on the numerical abilities of class X students of SMAN 1 Bae Kudus. The types and approaches of research used are correlation and quantitative. This study was conducted in class XE8 involving 32 students. The results showed that: (1) there was a positive and significant influence of mathematical disposition on numerical ability with a significant contribution of 0.000 < from 0.05, (2) there was no positive and significant influence of gender on numerical ability because the significance value was 0.975 > 0.05, and (3) there is a positive influence and the significant mathematical disposition and gender together to the numerical ability of significance values of 0.000 < 0.05 and a percentage of 61.1%.]]>

<![CDATA[Cognitive diagnostic models (CDMs) are multidimensional multivariate verification flow models with complex structure. In this research, these models were used to investigate the status of eighth grade high school students in mathematics using the TIMMS questionnaire. The cognitive diagnostic test based on 13 attributes including 32 questions was conducted on a sample of 274 students who were selected based on the multi-stage cluster sampling method among the students of Firuzkoh city. IRT and RESMA models were used to determine the psychometric properties of the questions. Data analysis using DINA and DINO models in cognitive diagnostic modeling of mathematics showed that 13 attributes explain the mathematical performance of eighth-grade students. The result shows that Afghan students have a weak mastery level in most attributes compared to 45 other countries (the countries that were included in the TIMMS questionnaire) also general results show that the examinees perform better in the field of numbers (0.49), while they perform worse in data and chance (0.12). Moreover, there exists some difference in estimating item parameters under the DINA and DINO models, such as Item 3 and Item 27. One possible explanation is that the DINA model is completely compensatory while the DINO model is fully non-compensatory. Similar to the results under the DINA model, the SEs of guessing parameters are lower than those of slipping parameters under the DINO model. ]]>

<![CDATA[The mathematical model in this study is a SCIR-type meningitis disease spread model, namely susceptible (S), carrier (C), infected (I), and recovery (R). In the model used, there are two equilibrium points, namely the disease-free equilibrium point and the endemic equilibrium point. The conditions and stability of the equilibrium point are determined by the basic reproduction number, which is the value that determines whether or not the spread of meningitis infection in a population. The results of this study show that the stability of the disease-free equilibrium point and the endemic equilibrium point are locally asymptotically stable and by using the Lyapunov Function method it is found that the disease-free equilibrium point will be globally stable when, while the endemic equilibrium point will be globally stable when numerical simulations perform to support the theoretical results.]]>

<![CDATA[This research focuses on studying the curriculum of three study programs at the Faculty of Science and Technology, namely Biology, Informatics Engineering and Architectural Engineering. The purpose of this research is to see how ready the curriculum of the 3 study programs is to be submitted as ASIIN international accreditation material. The method used to measure curriculum readiness is using AHP. The results of this study are that from 3 study programs that have been assessed using AHP, the study program that is most ready for its curriculum is Informatics Engineering with a readiness of 73.4%, followed by Architectural Engineering, and after that Biology.]]>
