Abstract

Perdagangan valuta asing (forex) merupakan salah satu instrumen investasi yang memiliki risiko tinggi dan memerlukan analisis yang tepat dalam pengambilan keputusan. Salah satu pendekatan yang banyak digunakan adalah analisis teknikal dengan bantuan indikator teknikal. Penelitian ini bertujuan untuk mengevaluasi kinerja tiga indikator teknikal, yaitu Moving Average periode 5 (MA5), Relative Strength Index (RSI), dan Parabolic SAR dalam memberikan sinyal beli dan jual terhadap pasangan mata uang EUR/USD. Permasalahan dalam penelitian ini  adalah untuk mengetahui sejauh mana efektivitas masing-masing indikator dalam membaca pergerakan harga dan menghasilkan profit yang optimal. Data yang digunakan adalah data historis EUR/USD periode 2018–2025 yang diperoleh dari platform MetaTrader 4, dengan pendekatan metode CRISP-DM dan pengolahan data menggunakan bahasa pemrograman Python. Hasil evaluasi menunjukkan bahwa Parabolic SAR merupakan indikator paling unggul dengan win rate 76.84%, net return sebesar 65.43%, dan CAGR sebesar 7.46%. MA5 menunjukkan hasil moderat dengan win rate 36.55% dan net return 6.15%, sedangkan RSI menunjukkan performa terendah dengan hasil negatif. Penelitian ini memberikan gambaran mengenai efektivitas masing-masing indikator teknikal dan dapat menjadi referensi untuk pengambilan keputusan trading yang lebih tepat. Kata Kunci: Evaluasi indikator teknikal, MA5, RSI, Parabolic SAR, pergerakan harga EUR/USD

Abstract

E-waste has become a critical global issue due to the rapid growth of electronic product consumption and the environmental risks associated with improper disposal. Traditional disposal methods, such as landfilling and incineration, are no longer sustainable as they lead to environmental degradation, health hazards, and loss of valuable resources. In contrast, remanufacturing, a key component of the circular economy, offers a more sustainable solution. This study explores the effectiveness of remanufacturing as a strategy for e-waste management, focusing on its ability to reduce waste generation and improve material efficiency in the electronics industry. The research utilizes a case study approach, examining industrial-scale remanufacturing processes, including material input-output analysis to track resource flows and waste streams. The findings reveal a significant reduction in e-waste generation, with up to a 50% decrease in waste volume, and substantial improvements in material recovery, particularly in metals like gold and copper. Additionally, the study highlights the economic and environmental benefits of remanufacturing, such as cost savings and resource conservation. However, the study also identifies barriers to the widespread adoption of remanufacturing, including technological, financial, and regulatory challenges. The results underscore the potential of a circular-economy-based remanufacturing model as a sustainable solution for the electronics industry. The study calls for further research into improving remanufacturing technologies, enhancing policy frameworks, and expanding circular economy practices across various industries.
