Abstract

Economic inequality in Sumatra remains an important issue in regional development, as reflected in disparities in income distribution across provinces. This inequality is presumed to be influenced by various factors, including access to financing, education levels, and regional economic performance. This study aims to analyze the effect of Islamic financing, average years of schooling, and Gross Regional Domestic Product (GRDP) per capita on economic inequality across 10 provinces in Sumatra during the period 2015–2024. The research employs a quantitative approach using panel data regression with the Common Effect Model, and data processing is conducted using EViews software to examine the relationships among variables. The results indicate that Islamic financing, average years of schooling, and GRDP per capita do not have a significant effect on economic inequality, either partially or simultaneously. The coefficient of determination of 2.33% suggests that the variables in the model explain only a small portion of the variation in economic inequality, while the remaining 97.67% is influenced by other factors outside the model. These findings imply that reducing economic inequality in Sumatra requires a more comprehensive approach by incorporating additional relevant variables.

Abstract

Penelitian ini bertujuan mengembangkan dan menganalisis kinerja sistem trading otomatis(Expert Advisor - EA) untuk mengatasi kegagalan trader akibat manajemen dana yangburuk dan keputusan emosional di pasar volatil Brent Oil (XBRUSD). Sistem inimengintegrasikan metode Fixed Ratio Money Management (FRMM) dengan indikatorteknikal Parabolic SAR dan Commodity Channel Index (CCI). Menggunakan metodeResearch and Development (R&D) model Waterfall , EA dikembangkan di MetaTrader 5dan diuji pada time frame H1 dan H4. Strategi EA didasarkan pada sinyal reversal yangdikonfirmasi kondisi oversold/overbought CCI (<-100 atau >+100). Kinerja sistemdievaluasi melalui backtesting (Jan 2021 - Jan 2024) dan real-time testing (Agu-Sep 2025).Hasil penelitian menunjukkan diskrepansi kinerja yang signifikan. Backtestingmenunjukkan profitabilitas sangat tipis (Net Profit H4: $95.91) namun dengan stabilitastinggi (Max Drawdown H4: 0.04%). Sebaliknya, real-time testing selama satu bulan gagalmenghasilkan profit dan merugi (Net Profit H4: $-1.46). Akurasi sinyal terbukti rendahdengan Win Rate di bawah 50% (Backtest H4: 41.10%). Disimpulkan bahwa metodeFRMM tidak efektif karena mekanisme peningkatan lot tidak pernah aktif, profit yangdihasilkan tidak pernah mencapai ambang batas "Delta" ($500-$2000) yang dibutuhkan.Stabilitas tinggi pada backtest murni disebabkan oleh strategi sinyal yang sangat konservatif dan frekuensi trading yang sangat rendah (73 trades/3 tahun), bukan karenamanajemen risiko FRMM yang superior

Abstract

Penelitian ini bertujuan untuk merancang, mengembangkan, dan mengevaluasi Expert Advisor (EA) yang menggabungkan indikator Relative Strength Index (RSI) dan Smoothed Moving Average (SMMA) untuk mendukung aktivitas perdagangan otomatis pada indeks US100 dengan menggunakan akun standar broker FXTM. Masalah utama yang diangkat adalah tingginya volatilitas US100 yang menyebabkan sinyal trading menjadi kurang akurat apabila parameter indikator menggunakan pengaturan default. Oleh karena itu, optimasi parameter dilakukan melalui metode grid search pada fitur Strategy Tester di MetaTrader 5 dengan menggunakan data historis selama lima tahun (Juli 2020–Juli 2025). Optimasi difokuskan pada periode RSI, level ambang RSI, serta periode SMMA. Evaluasi kinerja dilakukan melalui backtesting dan dilanjutkan dengan pengujian real-time untuk menilai tingkat kestabilan serta ketahanan strategi. Hasil penelitian menunjukkan bahwa penggunaan parameter yang telah dioptimasi mampu meningkatkan akurasi sinyal, rasio profitabilitas, dan efektivitas pengelolaan risiko dibandingkan parameter standar. EA terbukti lebih responsif dalam mengikuti arah tren, mengurangi kemunculan sinyal palsu pada kondisi volatil, serta menampilkan kinerja yang lebih konsisten pada kondisi pasar yang sedang tren maupun bergerak menyamping. Meski demikian, performa EA masih dipengaruhi oleh lonjakan volatilitas ekstrem sehingga memerlukan optimasi ulang secara berkala agar tetap relevan dalam kondisi pasar nyata.

Abstract

This research aims to study how Inventory Turnover and Return on Equity (ROE) impact stock prices in companies within the miscellaneous manufacturing industry listed on the Indonesia Stock Exchange from 2020 to 2020. This study uses a quantitative approach and is designed as a longitudinal quantitative study. The sample consists of ten companies selected purposively, resulting in 50 panel observations. Secondary data comes from official publications of the Indonesia Stock Exchange (IDX), as well as annual financial reports. The analysis was conducted using a panel data regression model and model selection tests (Chow, Hausman, Lagrange Multiplier), as well as t-tests, F-tests, and the coefficient of determination (R2). The research results indicate that inventory turnover are not significantly affected by stock prices (t-statistic < t-table; p > 0.05), suggesting that during the study period, inventory turnover efficiency was not yet a primary consideration for the market when assessing the value of industry stocks. Conversely, return on equity had a positive impact on stock prices (t-statistic > t-table; p < 0.05), indicating that the market was more responsive to a business's ability to generate profits from its own capital. Inventory Turnover and ROE significantly contribute to the simultaneous variation in stock prices (significant F-test), but the R2 value of 0.3143 indicates that these two variables account for approximately 31.43% of the variation in stock prices, with the remainder influenced by factors outside the model. Beside emphasizing the importance of improving profitability and report transparency for business management.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh inflasi, nilai tukar, penanaman modal asing (PMA), serta indeks produksi industri terhadap ekspor non-migas di Indonesia dengan menggunakan data sekunder berbentuk runtut waktu (time series) periode 2005-2024 yang disusun secara triwulanan dan diperoleh dari Badan Pusat Statistik, Bank Indonesia, serta Kementerian Perdagangan Republik Indonesia. Analisis dilakukan menggunakan metode regresi linear berganda dengan bantuan software EViews 12. Hasil pengujian menunjukkan bahwa secara parsial inflasi memiliki pengaruh negatif dan signifikan terhadap ekspor non-migas, sedangkan nilai tukar dan PMA berpengaruh positif dan signifikan, sementara indeks produksi industri tidak menunjukkan pengaruh yang signifikan. Secara simultan, seluruh variabel independen terbukti berpengaruh signifikan terhadap ekspor non-migas. Nilai koefisien determinasi sebesar 66,18% mengindikasikan bahwa model mampu menjelaskan variasi ekspor non-migas, sedangkan sisanya dipengaruhi oleh variabel lain di luar penelitian. Temuan ini mengindikasikan bahwa kinerja ekspor non-migas dipengaruhi oleh faktor makroekonomi dan sektor riil secara bersamaan, sehingga diperlukan kebijakan yang mampu menjaga stabilitas ekonomi sekaligus meningkatkan daya saing ekspor nasional.

Abstract

This study aims to examine the influence of financial literacy, capital market knowledge, and risk perception on the investment interest of students majoring in Management at the Faculty of Economics, State University of Medan. This study uses a quantitative approach through a survey method involving 67 respondents selected by purposive sampling, namely students from the class of 2022 who have attended the Capital Market School (SPM). The research instrument was declared valid and reliable, while data analysis was performed using multiple linear regression supported by classical assumption tests. The results showed that financial literacy did not have a significant effect on investment interest, capital market knowledge had a positive and significant effect, while risk perception did not have a significant effect. Simultaneously, all three variables had a significant effect on investment interest, with the model explaining 71.5% of the variation in interest. This study is novel in its use of SPM participation criteria in determining the sample and implies the need to strengthen capital market education to increase student investment interest.
