One method of predicting stock prices is to use the time series analysis method. In this method, a linear prediction model is made to see patterns from historical stock price data to assess future prices. The stock data used in this study is the daily stock data of PT. Telkom and PT. Indosat in 2020-2021. Autoregressive (AR) model is a time series model that is often used with the assumption that its volatility does not change with time (Homoscedastic). After analyzing the AR Model(1) data for the stock data of PT. Telkom and PT. Indosat has a non-independent error, therefore the AR(1)-N.GARCH(1,1) time series model construction was carried out to model the error (ϵ_(i,t)). Furthermore, the error of the AR(1)-N.GARCH(1,1) model is independent of t, so it can be modeled using Copula. After the Copula model was applied to the data and obtained the value of the fit of the Gaussian Copula distribution error model. From the values generated from the Gaussian Copula C({ϵ_(i,t) }_(t=1)^T ),T=1,2,…, and approximates a uniform distribution. So the stock data of PT. Telkom and PT. It can be said that Indosat is not suitable to be modeled with the Gaussian Copula.

The ability to think creatively is needed by students in mathematics learning activities, because creativity raises ideas in solving mathematical problems, so that the expected learning objectives are achieved. In addition, the mathematical resilience factor is needed to make students more persistent, never give up, enjoy being challenged, so that students' perspective on mathematics is not something to be afraid of anymore. This study aims to determine the effect of an open-ended approach on the mathematical creative thinking ability based on the mathematical resilience of Madrasah Tsanawiyah (MTs). This type of research is an experimental design that uses a factorial design. The selected population has been subjected to a one-way ANOVA test with the results having an average similarity, so that the sample was taken using the Cluster Random technique with randomly selected samples, namely class VIII-1 which was selected as the experimental class and class VIII-2 was selected as the control class. The results showed: 1) there were differences in mathematical creative thinking skills between students learning with open-ended learning and students learning using conventional learning; 2) there are differences in mathematical creative thinking abilities between students who have high, medium and low mathematical resilience; 3) while for interaction there is no interaction between the open-ended learning approach and students' mathematical resilience to mathematical creative thinking abilities. So the results of this study can be used to improve mathematics learning in class.

Transportation problems such as transportation activities and allocation to reach consumers is one of the factors that determine the level of satisfaction. To find the level of customer satisfaction, it requires an appropriate and efficient transportation model. One of which is in the Air Minum Mata Air Sikumbang business owned by Mr. Zulfikar, located in Rumbio, Kampar. Based on the results of the study the cost of distributing drinking water is still not efficient because it still uses estimation and there is no separate technique used to allocate water distribution. The solution made in this study using the Karagul-Sahin Approximation Method for the initial basic feasible solution and Stepping Stone for the optimal solution value so as to obtain the distribution of water at a minimum cost. Based on research using the method of Karagul-Sahin Approximation and Stepping Stone, a weekly cost savings of Rp.469.515,00 is obtained.
运输问题，如运输活动和分配，以达到消费者是决定满意度的因素之一。要找到顾客满意的水平，就需要一个合适的、高效的运输模式。其中一个是Zulfikar先生拥有的Air Minum Mata Air Sikumbang公司，位于Kampar的Rumbio。根据研究结果，分配饮用水的成本仍然不有效，因为它仍然使用估算，并且没有单独的技术用于分配水的分配。本研究采用Karagul-Sahin近似法求解初始基本可行解，采用Stepping Stone法求解最优解值，从而以最小的成本获得水的分配。根据Karagul-Sahin近似和Stepping Stone方法的研究，每周节省成本为469.51.5万卢比。

One of the reasons for the low student achievement in mathematics is that the mathematics learning process carried out by the teacher tends to be theoretical and less contextual. Mathematics learning needs to be linked to student culture so that there is no gap between mathematics in everyday life and at school. Thus, it is necessary to apply a mathematics learning model based on ethno-mathematics. This study aims to determine the effect of the ethnomatematic based probing-prompting learning model on students' mathematics learning achievement. This type of research is quantitative research with pre-experimental methods and one-group pretest-posttest design. The sample of this research is class VIII A SMPK St. Yoseph Naikoten Kupang, totaling 24 people. The pretest and posttest values as research data were analyzed using the SPSS version 22 program. Based on the results of data analysis, thitung (39,594)> ttabel (2,069) with an error rate of 0.05, which means accept Ha or the ethnomatematic based probing-prompting learning model has an influence which is significant towards the mathematics learning achievement of students class VIII SMPK St. Yoseph Naikoten Kupang.
学生数学成绩低的原因之一是教师进行的数学学习过程倾向于理论化，缺乏情境化。数学学习需要与学生文化联系起来，这样日常生活中的数学和学校里的数学就没有差距。因此，有必要应用一种基于民族数学的数学学习模式。本研究旨在探讨基于民族计量的探究提示学习模式对学生数学学习成绩的影响。这类研究是定量研究，采用实验前方法和一组前测后测设计。本研究样本为八甲SMPK St. Yoseph Naikoten Kupang，共24人。前测和后测值作为研究数据，使用SPSS version 22程序进行分析。从数据分析的结果来看，thitung (39,594)> tababel(2069)，错误率为0.05，说明接受Ha或基于民族变量的探索提示学习模式对SMPK St. joseph Naikoten Kupang八班学生的数学学习成绩有显著的影响。

Poverty is one of the main problems of the government that is prioritized in developing the development strategy of every country including Indonesia. The poverty rate in Indonesia is still relatively high, so the government focuses on decreasing the existing poverty level by improving the welfare of the population. Therefore, it is very important for the government to know the severity of poverty in Indonesia so that it can take a policy to reduce the existing poverty level. The purpose of the research was to group the severity of provincial poverty in Indonesia with a Discriminant Analysis. The stages of discriminant analysis include testing of normal multivariate distribution, testing of homogeneity of covariance variants, discriminant analysis by stepwise method, then continued calculation of classification accuracy value. The results of this research show that the large classification rate obtained is only 67.7% which means that not all provinces are able to be classified appropriately based on the variable open unemployment rate (TPT).
