Identifikasi Tingkat Warna Daun Padi dan Dosis Pemupukan Berdasarkan BWD (Bagan Warna Daun)
Abstract
Abstrak Padi merupakan salah satu tanaman pokok yang sangat penting dalam kehidupan, karena merupakan sumber bahan pangan pokok di Indonesia pada umumnya, tanaman padi memerlukan pupuk untuk perkembangannya dan keberlangsungan hidupnya agar dapat dipanen dengan memperhatikan dosis pemupukannya, untuk itu penelitian ini bertujuan merancang sistem untuk mendeteksi tingkat warna daun padi yang nantinya dapat dipakai sebagai pedoman dalam melakukan pemupukan, tingkat warna daun tersebut akan diukur melalui citra yang ditangkap oleh kamera Webcam Logitech sebagai penangkap citra dan raspberry pi sebagai pengontrol jalanya sistem, yang kemudian akan diolah untuk mendapatkan tingkat warna daun berdasarkan standart yang ada sekarang, yaitu BWD ( Bagan Warna Daun). Metode pendeteksi objek pada daun padi menggunakan metode color filtering pada ruang warna HSV, dengan menggunakan metode ini waktu yang dibutuhkan dalam memproses image processing pada webcam secara real time sekitar 5-10 detik, sedangkan untuk keakurasian dalam membedakan warna daun sacara manual dan dengan metode color filtering, dengan 20 sample daun padi masing masing pada tiap sample warna BWD,maka dihasilkan keakurasian menggunakan metode ini pada skala BWD nomor 2 sebesar 35%, BWD nomor 3 sebesar 45%, BWD nomor 4 sebesar 20% sedangkan BWD nomor 5 sebesar 15%. Kata kunci : BWD, Daun padi, Webcam, Color filtering Abstract Rice is one of the main crops that are very important in life, because it is a source of staple food in Indonesia in general, rice plants need fertilizer for their development and survival so they can be harvested by paying attention to the dosage of fertilization, for this study aims to design a system to detect levels the color of rice leaves which later can be used as a guide in fertilizing, the level of leaf color will be measured through the image captured by the Logitech Webcam camera as an image catcher and raspberry pi as a controller of the system's net, which will then be processed to get the leaf color level based on the standard there is now, the BWD (Leaf Color Chart). Object detection method on rice leaves using the color filtering method in the HSV color space, using this method the time needed to process image processing on the webcam in real time is around 5-10 seconds, while for accuracy in distinguishing leaf color manually and with the color method filtering, with 20 rice leaf samples each in each BWD color sample, accuracy is generated using this method on number 2 BWD scale of 35%, number 3 BWD is 45%, number 4 BWD is 20% while number 5 BWD is 15% keywords : BWD, Rice leaves, Webcam, Color filteringDownloads
