Abstract

Pohon regresi merupakan metode alternatif yang dapat digunakan untuk melihat hubungan antara peubah responkontinu dengan peubah-peubah penjelas. Metode pohon regresi menghasilkan dugaan piecewise constant atau piecewise lineardari model regresi. Penggunaan metode pohon regresi piecewice linear memberikan beberapa keunggulan dibandingkan metodepohon regresi piecewice constant. Metode pohon regresi picewice linear melibatkan peubah penjelas dalam model sehinggamampu mereduksi sisaan yang dihasilkan model picewise constant. Dengan demikian metode pohon regresi piecewice linearcenderung menghasilkan pohon regresi yang lebih pendek.Tulisan ini melihat penggunaan algoritma GUIDE dalam pohon regresi untuk model piecewice linear. Data yang digunakanterdiri dari data simulasi dengan mengambil satu peubah penjelas kontinu dan data sekunder dari internet dengan peubah responharga mobil dengan peubah-peubah penjelas berupa atribut-atribut mobil yang terdiri dari 10 peubah kategorik dan 13 peubahnumerik.Metode GUIDE menghasilkan kelompok-kelompok pengamatan yang memiliki model regresi yang lebih baik dibandingkandengan model regresi dengan melibatkan semua data. Disamping itu GUIDE mampu mejelaskan hubungan antara peubah respondan peubah penjelas yang bersifat kuadratik dengan menggunakan model regresi linier dengan terlebih dahulu membentukkelompok-kelompok pengamatan berdasarkan peubah penjelas yang digunakan.

Abstract

Transformasi IAIN ke UIN adalah merupakan implementasi integrasi keilmuan, Sehingga menghasilkan konsep pemikiriran integrasi keilmuan. UIN Suska Riau sendiri dalam logo nya tercermin integrasi keilmuan yaitu spiral Andromeda yang memiliki makna filosofis integrasi tiga bidang keilmuan agama, sains dan humaniora. Tujuan penelitian adalah bagaimana studi penulisan skripsi di UIN Suksa Riau pada Fakultas Tarbiyah dan Keguruan pada jurusan Pendidikan Ekonomi yang terkait pada integrasi keilmuan. Metode dalam penelitian ini adalah kualitatif deskriptif dengan teknik pengumpulan data observasi dan wawancara. Hasil penelitian bahwa studi penulisan skripsi di Jurusan Pendidikan Ekonomi belum menggambarkan integrasi keilmuan agama, pendidikan dan ekonomi secara keseluruhan namun ada beberapa skripsi mahasiswa yang integrasi dengan nilai-nilai islam. Hal tersebut di karenakan belum terimplementasi pada regulasi dan metode. Dari sebanyak 61 sampel skripsi tidak ditemukan pemikiran atau model integrasi ilmu agama, pendidikan dan ekonomi. Namun telah menunjukkan integrasi antar satu rumpun ilmu ekonomi dan integrasi dengan ilmu pendidikan dan ekonomi. Tema yang sering diminati mahasiswa dalam judul skripsi adalah tentang strategi pembelajaran, karakter siswa serta kewirausahaan. Hasil penelitian menunjukkan bahwa kurangnya pemahaman dan regulasi dalam implementasi penerapan konsep integrasi keilmuan di UIN Suska Riau.

Abstract

The pandemic period that started in 2019 has caused many businesses to collapse, the JCI is at the level of 6,244 (24 Jan). This resulted in the closing of the capital market on March 13, 2020 after the WHO announcement that the COVID-19 outbreak was a pandemic. Nevertheless (Rizal, 2021; 1) the reality shows that the Indonesian capital market is still growing with the increase in the number of investors, especially retail investors. This study aims to determine the behavior of market participants, namely investors and traders through stock prices. The population used in this study were 18 companies whose shares were actively traded in 2019 and 2020 and semester 1 2021, the sample was taken from companies whose shares received top gainers. The analytical model used is MRA or moderated regression analysis. The results of the study show that the capital market's revival during the pandemic is caused by the motivation of traders to obtain short-term results, namely capital gains, by using the stock's intrinsic value benchmark, without conducting in-depth technical analysis. This shows that stock prices will move randomly following past patterns which have not been proven in the pandemic conditions in Indonesia.

Abstract

Financial management is one of the main courses at the Faculty of Economics and Business. However, this course is often considered a difficult subject for some students. This study is a qualitative study with a theoretical perspective by constructing a financial management visualization scheme. The aim is to provide illustrations that provide a complete view to make it easier to understand financial management. The discussion is given in a comprehensive manner regarding the function of financial management, namely seeking funds in an efficient composition, making investments effectively, and dividing profits (dividends) strategically as shown in a brief financial report. This financial management function is carried out to achieve company goals, namely the value of the firm in the form of stock prices. The results show that it does not only provide benefits for shareholders or owners, but also long-term benefits for stakeholders or related parties in the form of corporate social responsibility.

Abstract

The capital market carries out transactions online, which provides opportunities for people to invest. It is very impressive that it seems as if the capital market is not affordable for the public and the ease of access to the capital market as an investment opportunity is less likely to be captured by the majority of the public due to a lack of understanding about investing in the capital market. This study aims to provide understanding and education regarding processes and strategies in the capital market, so that the public can actively participate in investment activities in the capital market. This study is a qualitative descriptive study by developing an investment scheme and strategy that provides illustrations to facilitate understanding of investors in the capital market. The results of this research are a comprehensive picture of investing starting with the investment process, stock trading mechanisms, various aspects of analysis and investment strategies, so that investors can make investment decisions. The implication of this study is that investors need to determine their investment objectives and have an understanding of investing in the capital market before making investment decisions.
