In face recognition research, detecting several parts of the face becomes a necessary part of the study. The main factor in this work is lighting; some obstacles emerge when the low light's intensity falls in the process of face detection because of some conditions, such as weather, season, and sunlight. This study focuses on detecting faces in dim lighting using the Local Binary Pattern Histogram (LBPH) algorithm assisted by the Classifier Method, which is often used in face detection, namely the Haar Cascade Classifier. Furthermore, It will employ the image enhancement method, namely Histogram Equalization (HE), to improve the image source from the webcam. In the evaluation, different light intensities and various head poses affect the accuracy of the method. As a result, The research reaches 88% accuracy for successful face detection. Some factors such as head accessories, hair covering the face, and several parts of the face, like the eye, mouth, and nose that are invisible, should not be extreme.
Saat ini telah menjadi trend coin cryptocurrency sebagai aset mata uang digital yang semakin meningkat sehingga membuat semua orang berlomba dalam melakukan mining atau menambang coin cryptocurrency seperti bitcoin dan etherum. Untuk mendapatkan keuntungan dari cryptocurrency ada beberapa cara yaitu dengan mining serta trading. Aktivitas mining dan trading cryptocurrency mulai banyak dikenal dimana pada saat melakukan aktivitas mining atau menambang para miner akan melakukan proses menambang cryptocurrency menggunakan perangkat komputer. Sedangkan pelaku trading atau sering disebut dengan trader akan melakukan aktivias jual beli coin cryptocurrency melalui exchanger dengan menganalisa pegerakan harga pada market yang begitu cepat.BOT merupakan kependekan dari robot, sebuah robot yang salah satu fungsinya untuk memudahkan tugas manusia. [1] Dengan adanya BOT ini mempermudah kita dalam melakukan trading cryptocurrency secara otomatis dan dapat di monitoring melalui Telegram BOT yang akan mengirim notifikasi ketika berhasil melakukan aktivitas transaksi penjualan serta pembelian pada website exchanges cyrptocurrency dengan menganalisa pegerakan harga coin cryptocurrency menggunakan metode peramalan Exponential Moving Average. Pemanfaatan metode Exponential Moving Average dapat memperoleh hasil perhitungan peramalan harga cryptocurrency sebesar 5819329 untuk 4 Day EMA dan 5821928 untuk 8 Day EMA dengan nilai Mean Absolute Error untuk 4 Day EMA sebesar 7774 dan untuk 8 Day EMA sebesar 3521 dan nilai Mean Squared Error untuk 4 Day EMA sebesar 89322503 dan untuk 8 Day EMA sebesar 18740267. Kata kunci: Bot, coin cryptocurrency, Exponential Moving Average, Telegram
