Portofolio Optimization Through MPT on any Economic Situation on Indonesian Stock Exchange (2010-2020)

Abstract Modern portfolio theory told us that investors are tend to optimize the expected return of investment subject to a target of risk perception. In the real world, risks are depend on may factors, such as systematic risk (market risk and macroeconomics risk which can not be controlled to diversification) and non-systematic risk (specific company risk which can not be controlled through diversification). Applying Security Market Line Approach, constrained maximization and considering changes in economic situation between 2010-2020, we found that Modern Portfolio Theory can improve portfolio performance when limited impact is spotted on minimizing systematic risk of portfolio.</jats:p

Using by E-Learning with Information Theory Adaptive Model to Increase Self-Regulated Learning Students

Abstract This study aims to describe the influence of Elitas’ model on self-regulated learning Students and student learning outcomes at Semester January –June 2020 of Mathematics Education Study. The type of research used in this research was descriptive research with the design of one shot case study. The subjects in this study were students who were English for Mathematics course in the scope of 72 people in the FMIPA UNP. The instrument that will be used in this study is in the form of learning outcomes test and student self-regulated learning questionnaire sheets. Analysis of the data used are percentage analysis and to test hypotheses used t-test. The results showed by student learning independence score has a mean of 88.72 and high percentage of independence in using knowledge and experience was 79.17%. Based on student learning outcomes, it was a significant effect of in terms of there are differences in student learning outcomes before and after using the Elita model in EFM lectures.</jats:p

Modified For The Pascal Triangle Multinomial

Abstract Newton’s Binomial Theorem applied at the rate of 2 with the formula: ( a 1 + a 2 ) n = ∑ r = 0 n C ( n , r ) a 1 n − r a 2 r Problems in algebra are not limited binomial. Binomial only is not enough, so that multinomial is necessary. Multinomial Theorem has the formula: ( a 1 + a 2 + … + a k ) n = ∑ n 1 , n 2 , … , n k ≥ 0 n ! n 1 ! n 2 ! … n k ! a 1 n 1 a 2 n 2 … a k n k The use of theorem in binomial problem is less practical so that Pascal Triangle is prefered, for easier use Pascal’s Triangle. Solution of Triangle with the theorem multinomial problem more complicated. By analyzing multinomial through binomial form, can be obtained from modification that allows the Pascal triangle. The focus of the discussion is to determine Pascal Modified Triangular shape of a multinomial. This basic research using descriptive method, by analyzing the relevant theory is based on the study of literature. The results obtained are Modified Pascal’s Triangle, which facilitates the work in the multinomial.</jats:p

Application of the E-Learning with Adaptive Theory Information Model in English for Mathematics Lectures

Abstract After the emergence of the Covid-19 outbreak, the education system began to look for the latest innovations to form an effective lecture process with a learning model that was suitable for students in distance learning using the E-Learning learning model which was been adaptive additional information was needed. It;s known as the Elita model. The purpose of this research is to produce profile information about Elita's users who are categorized, in student's achievement and student's preferences in English for Mathematics lectures. This type of research is a mixture of qualitative and quantitative. Quantitative data were obtained from tests, and qualitative data were obtained from interviews and observations. The population is students of Mathematics Education, Universitas Negeri Padang. The sample was 43 students from January to June 2020 semesters. The instruments used were interview guides, field notes, and tests. The results obtained were the achievement of student's achievement in understanding the EFM lecture material, an increase in the average score, while the results of student’s preference in the EFM lecture process with the Elita model was moderate.</jats:p

The Effectiveness of Student Worksheet Based on 4’Cs Skills to Improve Higher Order Thinking Skills Students’ SMP Pekanbaru

Abstract This study aims to determine the effectiveness of Student Worksheet (LKPD) based on 4'Cs skills and its effect on improving higher-order thinking skills of class VIII SMPN 4 Pekanbaru. The design used in this study was pre-experimental with the Static Group Comparison design. The data analysis technique was performed using statistical t-test. The results showed that this LKPD was declared effective as a learning innovation based on indicators of higher-order thinking skills. The effectiveness of the LKPD based on 4'Cs skills is proven to be influential in improving higher-order thinking skills based on the acquisition of results using the difference test.</jats:p

Analysis of Student’s Satisfaction to Academic Service in FMIPA Universitas Negeri Padang

Abstract It paper discuss about student’s satisfaction to academic services in FMIPA. It conclude facility and infrastructure, lecturer and education staff, and also student service. We use primer data from around 308 students. Questionnaire are arranged depend on tangibles, reliability, responsiveness, assurance and empathy. Based in data analysis, we conclude that all students less satisfied to the academic services in FMIPA. But, depend on analysis for each item, there are some points we have to increase, like lack of parking area, toilet, and religion facility for students which is prepared by faculty. It can be follow-up by faculty.</jats:p

Analysis of High Order Thinking Skill of Students in Contextual Problems Solving

Abstract This study aims to analyze the high-order thinking skills of students in solving contextual problems in calculus lectures. Currently, students are required to be more creative in solving calculus problems that lead to High Order Thinking Skill (HOTS) thinking, where students apply the knowledge and skills that have been developed during lectures in a new context. This type of research is qualitative, with a descriptive presentation method and a case study approach. The subjects in this study were six students of the January-June 2020/2021 semester mathematics education study program who were selected based on their level of ability to solve contextual questions. The data collection techniques used in this study were observation and written tests presented in contextual problems. Based on the research results, it can be concluded that student HOTS is determined by the student's ability to solve contextual questions, the higher the student's ability to solve contextual questions, the more HOTS indicators are achieved. HOTS students with high abilities are able to meet indicators of analyzing, evaluating, and creating. HOTS students with moderate ability are able to meet the indicators of analyzing and evaluating. HOTS students with low ability are able to only meet the analyzing indicators, The results showed that there were differences in HOT problem solving among students with high, medium and low abilities.</jats:p
