Abstract

Pasar valuta asing atau forex merupakan salah satu pasar keuangan terbesar di dunia, dengan volume perdagangan harian yang mencapai triliunan dolar. Perdagangan forex memerlukan analisis yang cermat dan strategi yang tepat untuk meminimalkan risiko dan memaksimalkan keuntungan. Salah satu alat yang dapat digunakan untuk membantu trader dalam mengambil keputusan adalah Expert Advisor (EA), yang dirancang menggunakan bahasa pemrograman MQL4. Penelitian ini bertujuan untuk merancang sebuah Expert Advisor yang dapat berinteraksi dengan pasar forex, khususnya pada pasangan mata uang AUD/USD. Sistem EA ini didasarkan pada algoritma analisis teknikal yang menggunakan indikator moving average (MA) untuk mengidentifikasi tren harga dan pola data harga. Proses perancangan EA ini mencakup pembuatan kode, implementasi, dan pengujian. Pada penelitian ini, backtesting dilakukan untuk periode 1 Januari 2024 hingga 30 Juni 2024 dengan modal awal sebesar 10,000 USD, pasangan mata uang AUD/USD, timeframe M15, dan leverage 1:100. Hasil backtesting menunjukkan bahwa EA yang dirancang dapat menghasilkan profit sebesar 157.56 USD pada bulan Mei dan total net profit sebesar 89.99 USD pada bulan Juni. Meskipun hasil yang diperoleh belum maksimal, penelitian ini menunjukkan bahwa penggunaan indikator moving average sebagai dasar logika EA dapat membantu dalam pengambilan keputusan trading.

Abstract

The manual management of student dormitory administration at Manado State University presents several challenges, particularly related to record accuracy, service effectiveness, and information protection. This research focuses on the development of a web-based dormitory management information system using the Advanced Encryption Standard (AES) 128-bit algorithm as a data security mechanism, particularly for payment documents. The research method used is a prototype model, which includes communication, rapid planning, modeling, prototype development, and testing. The system is implemented using PHP and MySQL, with the integration of AES-128 encryption in the payment receipt upload feature to ensure data confidentiality. The results of black-box testing show that all system functions run according to user requirements. The implementation of AES-128 has been proven to maintain the security of sensitive data and increase user trust in the system. Key features provided include user registration, room reservations, payments, facility reporting, and notifications, while administrators are given full access rights to manage resident and room data, as well as encrypt and decrypt important information. Overall, this research produces a system that not only improves the efficiency and effectiveness of dormitory management but also strengthens data security aspects. The developed system has the potential for further enhancement through mobile application integration and the implementation of an automated payment system to be more responsive to user needs. Cryptography is a field of science that utilizes mathematical techniques to ensure data and information security, including authentication, integrity, and validity
