Penerapan E-Learning Mata Kuliah Matematika Ekonomi bagi Mahasiswa Ekonomi dan Bisnis Islam

Economics mathematics courses are abstract and require high thinking activities. Nevertheless, all students studying in the Islamic Economics study program FEBI IAIN Bengkulu must learn it because it is one of the compulsory subjects in the Islamic Economics program FEBI IAIN Bengkulu that must be taken. Learning mathematics economics needs to need learning media that can improve students' understanding in learning economic mathematics. With the media, students are given the ease of visualization of the material presented, including series, linear functions and things needed in economic mathematics learning. accurate for users so that they can be used as a choice of learning media in teaching and learning processes, inspire lecturers to use web media in the teaching and learning process and students can study anywhere without being limited by space and time. The method used is research and development or in English Research and Development is a research method that is used to produce certain products, and test the effectiveness of these products used in this study is the software used in this application is moodle, xampp and internet.  Keywords :Moodle, Xampp, Internet

Suatu sistem persamaan linier akan dibuat dengan menggunakan persamaan aproksimasi beda hingga Caputo. Kemudian hasil dari system persamaan linier tersebut diselesaikan dengan menggunakan metode iterasif numerik Half-Sweep Preconditioned Gauss-Seidel (HSPGS) dimana efektivitasnya akan dibandingkan dengan metode Preconditioned Gauss-Seidel (PGS), (dikenal juga sebagai Full-Sweep Preconditioned Gauss- Seidel (FSPGS)) dan Gauss-Seidel (GS) sebagai metode kontrol. Contoh masalah juga disajikan untuk menguji efektivitas metode yang diusulkan. Temuan penelitian ini menunjukkan bahwa metode iteratif yang diusulkan yaitu HSPGS lebih unggul dibandingkan dengan metode FSPGS dan GS

Performance numerical method half-sweep preconditioned gauss-seidel for solving fractional diffusion equation

The main purpose, we derive a finite difference approximation equation from the discretization of the one-dimensional linear space-fractional diffusion equations by using the space fractional derivative of Caputo's. The linear system will be generated by the Caputo's finite difference approximation equation. The resulting linear system was then resolved using Half-Sweep Preconditioned Gauss-Seidel (HSPGS) iterative method, which compares its effectiveness with the existing Preconditioned Gauss- Seidel (PGS) or call named (Full-Sweep Preconditioned Gauss-Seidel (FSPGS)) and Gauss-Seidel (HSPGS) methods. Two examples of the issue are provided in order to check the performance efficacy of the proposed approach. The findings of this study show that the proposed iterative method is superior to FSPGS and GS. © 2020 International Information and Engineering Technology Association

MEMBANGUN BANGSA INDONESIA DENGAN TEKNOLOGI INFORMASI DAN KOMUNIKASI

The rapid  development of information and  communication technology (read: ICT) has  changed the procedure for humans act and behave today, as well as college graduates as an elite human capital, particularly in relation  to the  process of communication and  interaction. It is a fact that  almost  all industrial  fields and aspects of modern life do not escape the reach of this technology, because it has been proven to be able to bring a number of value and benefit  to the national  development significant Indonesia and civilization of mankind in this world. With the advancement in the field of ICT is growing at an exponentially and take the positives out of the field of ICT is expected to be Indonesian nation to excel in all areas

Implementation of the half-sweep AOR iterative algorithm for space-fractional diffusion equations

In this paper, we consider the numerical solution of one dimensional space-fractional diffusion equation. The half-sweep AOR (HSAOR) iterative method is applied to solve linear system generated from discretization of one dimensional space-fractional diffusion equation using Caputo’s derivative operator and half-sweep implicit finite difference scheme. Furthermore, the formulation and implementation of HSAOR iterative method to solve the problem are also presented. Two examples and comparisons with FSAOR iterative method are given to show the effectiveness of the proposed method. From numerical results obtained, it has shown that the HSAOR iterative method is superior as compared with the FSAOR methods

DAMPAK MEDIA SOSIAL TERHADAP PAHAM RADIKALISME

The purpose of this paper is to see the impact of social media on the idea of radicalism. In writing this paper using literature study method. And from the description in this paper can be concluded that social media have a positive and  negative impact. The negative impact of the free use of social media is the ease of accepting the Indonesian public receiving information including radicalism from all fields without finding out the truth of this information.

Analisis Good Corporate Governance pada Kinerja Keuangan Bank Umum Syariah yang Terdaftar di Bursa Efek Indonesia (BEI) Periode 2018-2020

The purpose of this study was to determine whether the board of commissioners, board of directors and audit committee have an effect on financial performance as measured by using ROA. This type of research is quantitative descriptive. The data used in this study are Islamic commercial banks listed on the Indonesia Stock Exchange (IDX) for the 2018-2020 period. The analysis technique used is panel data regression with the help of Eviews 10. The results of this study partially show that the board of commissioners and the audit committee have no effect on financial performance, while the board of directors has an influence on financial performance. Meanwhile, simultaneously the three variables, namely the board of commissioners, the board of directors and the audit committee jointly affect the financial performance of Islamic commercial banks listed on the Indonesian Stock Exchange (IDX)

Application half-sweep preconditioned SOR method for solving time-fractional diffusion equations

This research examines the performance of the application Half-Sweep Preconditioned SOR (HSPSOR) method together with an unconditionally implicit Caputo’s time–fractional finite difference approximation equation for solving time-fractional partial diffusion equations (TFPDE’s). To do it, the implicit Caputo’s time-fractional approximation equations and preconditioned matrix are used to construct the corresponding preconditioned linear system. In addition to that, formulation and application the HSPSOR method are also presented. Based on numerical results of the proposed iterative method, it can be concluded that the proposed iterative method is superior to the Full-Sweep PSOR iterative methods

Pengaruh Return on Assets (ROA) , Debt to Equity Ratio (DER) , dan Current Ratio (CR) terhadap Nilai Perusahaan pada Jakarta Islamic Index 70

This study aims to determine the effect of Return On Assets, Debt To Equity Ratio and Current Ratio partially and simultaneously on firm value on the Jakarta Islamic Index 70 (JII70) in 2018-2020. Several previous studies on firm value showed different results. So, other research needs to be done to retest the theory of firm value. This research is a type of correlational analysis research with a quantitative approach. The research population was 70 companies on the Jakarta Islamic Index 70. The sampling method used the purposive sampling technique. So that the sample in this study was 28 companies during 2018-2020. The source of data collection used is in the form of numbers obtained from the www.idx.co.id website and the official website. The data analysis technique used multiple linear regression analysis. The data analysis process carried out is descriptive statistics, basic assumption test, classical assumption test, hypothesis test and determination coefficient test. The results showed that partially Return On Assets had no significant effect on firm value. Debt To Equity Ratio has a significant negative effect on firm value. While the Current Ratio has a significant effect on firm value. Simultaneously, the Debt To Equity Ratio and the Current Ratio have a simultaneous effect on the firm value of 7.1%. While the remaining 92.9% was influenced by other factors that were not included in this study
