Abstract

Tebu (Saccharum officinarum) merupakan tanaman perkebunan penting sebagai penghasil utama gula di Indonesia. Penurunan produksi gula tebu dalam beberapa tahun terakhir tidak sejalan dengan permintaan gula tebu yang kian meningkat. Pemuliaan tanaman diarahkan untuk mendapatkan varietas-varietas tebu unggul yang diharapkan memiliki produktivitas tinggi dan tahan terhadap faktor-faktor gangguan yang dapat menurunkan produktivitas tanaman. Pengamatan penyakit mosaik bergaris (Sugarcane streak mosaic virus/SCSMV), pokahbung (Fusarium moniliforme), dan luka api (Sporisorium scitamineum) dilakukan pada 14 klon tebu unggul di PG Krebet Baru, Malang. Pengamatan intensitas penyakit dilakukan setiap 2 minggu selama 3 bulan dan sampel tanaman yang menunjukkan gejala penyakit dideteksi penyebab penyakitnya di laboratorium. Gejala penyakit mosaik bergaris terjadi pada tiga klon tebu dengan intensitas antara 8.33% dan 63.89%; sedangkan gejala penyakit pokahbung dan luka api ditemukan pada 11 dan 14 klon tebu dengan intensitas berturut-turut 2.78% sampai 22.22% dan 11.11% sampai 25%. Konfirmasi keberadaan SCSMV diperiksa dengan metode polymerase chain reaction; sedangkan cendawan F. moniliforme dan S. scitamineum melalui isolasi jaringan dan pengamatan jaringan meristem. Secara umum insidensi penyakit tergolong rendah pada klon 8 dan 12 sehingga klon tersebut dapat direkomendasikan sebagai klon potensial yang digunakan dalam mengendalikan penyakit utama tebu.

Abstract

Kenaf fiber is mainly used for forest wood substitute industrial products. Thus, the kenaf fiber can be promoted as the main composition of environmentally friendly goods. Unfortunately, there are several Kenaf gardens that have been stricken with the disease-causing a lack of yield. By utilizing advances in technology, it was felt to be able to help kenaf farmers quickly and accurately detect which pests or diseases attacked their crops. This paper will discuss the application of the machine learning method which is a Convolutional Neural Network (CNN) that can provide results for inputting leaf images into the results of temporary diagnoses. The data used are 838 image data for 4 classes. The average results prove that with CNN an accuracy value of 73% can be achieved for the detection of diseases and plant pests in Kenaf plants.

Abstract

One of the advantages of Kenaf fiber as an environmental management product that is currently in the center of attention is the use of Kenaf fiber for luxury car interiors with environmentally friendly plastic materials. The opportunity to export Kenaf fiber raw material will provide significant benefits, especially in the agricultural sector in Indonesia. However, there are problems in several areas of Kenaf's garden, namely plants that are attacked by diseases and pests, which cause reduced yields and even death. This problem is caused by the lack of expertise and working hours of extension workers as well as farmers' knowledge about Kenaf plants which have a terrible effect on Kenaf plants. The development of information technology can be overcome by imparting knowledge into machines known as artificial intelligence. In this study, the Convolutional Neural Network method was applied, which aims to identify symptoms and provide information about disease symptoms in Kenaf plants based on images so that early control of plant diseases can be carried out. Data processing trained directly from kenaf plantations obtained an accuracy of 57.56% for the first two classes of introduction to the VGGNet19 architecture and 25.37% for the four classes of the second introduction to the VGGNet19 architecture. The 5×5 block matrix input feature has been added in training to get maximum results.
