The Regional Competitiveness Index (RCI) is one of the essential indicators to measure the ability of a region to compete with other regions in the economic, social, and environmental fields. Increasing regional competitiveness is one of the goals desired by every local government to encourage economic growth and community welfare. This study aims of the research to find out the relationship between the Regional Competitiveness Index (RCI) and socioeconomic macroeconomic variables such as the growth of Gross Regional Domestik Bruto (GRDP), Human Development Index (HDI), Foreign Investment, Domestic Investment, Regional Income and poverty rates in Indonesia in 2022 in Indonesia. The data used are publication data from the National Innovation Research Agency (BRIN) and the Statistic Indonesia (BPS) in 2022. The analysis model used is the PLS Structural Equation Model (SEM) model with SmartPLS software. The results showed that RCI significantly positively affected HDI, GRDP growth, Domestic Investment, Foreign Investment, and Regional Income. On the other hand, RCI significantly negatively affects the percentage of poor people. A comprehensive and targeted policy is needed so that the Regional Saiang Power Index continues to increase. In addition, supervision is needed related to programs that have been running related to regional competitiveness

This study aims to predict the movement of Bank Syariah Indonesia shares (BRIS.JK) prices using the Conditional Restricted Boltzmann Machine (CRBM) method. Prediction is needed in conducting share transactions, because the increase or decrease in share price movements is very difficult to predict. The CRBM method is a machine learning algorithm used to model the probability distribution of data associated with variables and inputs. CRBM is a type of Restricted Boltzman Machine (RBM) that consists of two layers, namely the input layer and the hidden layer. CRBM is a type of Boltzmann machine model equipped with a conditioned unit that is used to perform analysis and learning on data that has conditional properties. In this research, the first step is to divide several research scenarios. Then conduct CRBM tests to get prediction results. The data used is daily close data. Based on the research that has been done, it is obtained that the best prediction accuracy is in July - August with MAPE below 5%.

This study aims to determine the effect of applying the Flipped Classroom learning model integrated with Problem Based Learning on the numeracy skills of high school students. The research sample consisted of 39 experimental class students who used the flipped classroom model integrated with Problem Based Learning and 39 control class students who used the Problem Based Learning model from the population of SMAN 5 Serang city. The research method used was quasi experiment. The instrument used in collecting data was a test instrument in the form of a pretest and postest consisting of three description questions. The data were analyzed by one-way anova test with a significance level of 0.05 to see the average difference between the two classes. The results showed that the pretest value of numeracy skills obtained a Sig. 0.159 > 0.05 so that H_0 is accepted. meaning that the experimental class and control class have the same initial ability. then for the posttest value of numeracy skills obtained a Sig value. 0.21 <0.05 so that H_0 is rejected. This means that there is an average difference in numeracy skills between the experimental class and the control class. When viewed from the average numeracy skills of experimental class students are smaller than the control class, namely 40.05 < 51.51. Thus, the Problem Based Learning learning model is better than the Flipped Classroom model in improving the numeracy skills of high school students on the material of the system of linear equations of three variables

The sample in this study was taken by cluster random sampling technique. Data collection techniques include interviews, observations, tests, validation, and documentation. The data analysis technique used is the analysis of the average difference in significance test between the two groups with test prerequisites, namely normality tested using the Liliefors test and homogeneity tested using the Bartlett test. Based on the results of analysis and data processing using the t-test, it was obtained that the Sig. (2-tailed) value < 0.05 which means that the rejected and with a significant level of 5%. Based on these results, it can be concluded that there is an influence of the flashcard-assisted Problem Based Learning learning model on the mathematical problem solving ability of grade VIII. This can be a reference that the flashcard-assisted Problem Based Learning model can be used as a relevant learning model to improve students' mathematical problem-solving skills","PeriodicalId":31699,"journal":{"name":"JMPM Jurnal Matematika dan Pendidikan Matematika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90847430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
