Pengujian Akurasi Aplikasi BioLeaf dalam Menentukan Luas Serangan Serangga Pemakan Daun

Abstract

Serangan hama pada daun tanaman berdampak signifikan terhadap penurunan produktivitas tanaman, karena daun merupakan organ vital dalam proses fotosintesis dan menjadi indikator awal kerusakan fisiologis tanaman. Oleh karena itu, pengukuran luas kerusakan daun penting dalam menilai kesehatan tanaman dan keefektifan pengendalian hama. Metode konvensional seperti kertas milimeter, gravimetri, dan planimeter dinilai kurang praktis dan rawan kesalahan, terutama jika jumlah sampel banyak. leaf area meter (LAM) memiliki keterbatasan yaitu memerlukan biaya tinggi. Aplikasi BioLeaf hadir sebagai solusi berbasis smartphone yang menawarkan kemudahan, efisiensi, dan kepraktisan dalam pengukuran luas kerusakan daun secara digital. Penelitian ini bertujuan menguji akurasi aplikasi BioLeaf dalam menentukan luas serangan serangga pada daun tanaman. Penelitian dilakukan di Kampung Carang Pulang, Desa Cikarawang, Kecamatan Dramaga, Kabupaten Bogor, serta di Laboratorium Klinik Tanaman, Departemen Proteksi Tanaman, Fakultas Pertanian, Institut Pertanian Bogor, dengan menggunakan 14 sampel daun dari berbagai jenis dan tingkat kerusakan dan dilakukan 5 perlakuan serta menggunakan 3 Perangkat (kamera, smartphone 1 dan smarphone 2). Hasil pengukuran menggunakan BioLeaf dibandingkan dengan metode manual dan ImageJ untuk menilai tingkat akurasinya. Hasil penelitian menunjukkan bahwa BioLeaf memiliki akurasi tinggi dan dapat menjadi alternatif praktis serta efisien dalam pemantauan kerusakan daun di lapangan bagi petani dan peneliti.

Pest attacks on plant leaves have a significant impact on the reduction of crop productivity, as leaves are vital for photosynthesis and serve as early indicators of physiological damage. Therefore, measuring leaf damage is essential for assessing plant health and the effectiveness of pest control. Conventional methods such as millimeter paper, gravimetry, and planimetry are often impractical and prone to error, especially with large sample sizes, while Leaf Area Meter (LAM) are limited by high costs. BioLeaf, a smartphone-based application, offers a practical, efficient, and user-friendly digital solution for measuring leaf damage. This study aimed to evaluate the accuracy of BioLeaf in determining pest damage on leaves, conducted in Kampung Carang Pulang, Cikarawang Village, Dramaga District, Bogor Regency, and at the Plant Clinic Laboratory, Department of Plant Protection, Faculty of Agriculture, IPB University. Fourteen leaf samples with varying types and levels of damage were analyzed using five treatments and three devices (a camera, smartphone 1, and smartphone 2). Measurements from BioLeaf were compared to manual methods and ImageJ software to assess accuracy. The results showed that BioLeaf has high accuracy and can serve as a practical and efficient alternative for monitoring leaf damage in the field, providing benefits for both farmers and researchers
