Abstract

Penggunaan tekhnologi visual seperti pengolahan citra (image processing) dapat mempermudah dalam proses menganalisa suatu objek tanpa berhubungan langsung dengan objek yang akan diamati. Citra daun tanaman kelapa sawit melalui pengolahan citra dapat dianalisa melalui  tingkat kehijauan daun dan pola yang ada pada daun sehingga dapat mengetahui kesuburan tanaman kelapa sawit. Penelitian ini dilaksanakan di PT. Perkebunan NusantaraII kebun Limau Mungkur. Penelitian ini dilaksanakan  dari bulan Desember 2018 – Juli 2019 yang dimulai dari pengambilan sampel daun sampai dengan pengolahan data. Penelitian ini menggunakan metode analisa deskriptif, yaitu  dengan cara mengumpulkan sampel daun yang dibutuhkan untuk dianalisa dengan menggunakan software image processing, kemudian dideteksi untuk mengetahui pola bentuk daun yang terserang penyakit garis kuning pada daun tanaman kelapa sawit. Hasil dari penelitian yang telah dilakukan maka dapat diambil kesimpulan yaitu: perbedaan antara daun sehat dengan daun yang terserang penyakit garis kuning pada tanaman kelapa sawit dapat dibedakan dengan jelas karena pola bercak yang ada pada masing-masing daun dapat dipolakan dengan warna. Pada daun sehat hanya da pola garis vertikal yang berwarna gelap dan tidak terdapat bercak pada badan daun. Berbeda dengan daun yang terserang penyakit garis kuning, pada permukaan daun yang terserang penyakit terdapat pola-pola seperti bercak, semakin banyak pola-pola tersebut maka semakin berat tingkat serangan penyakit tersebut. Nilai bercak pada masing-masing grade penyakit tersebut berhasil didapatkan melalui proses image processing yang berdasarkan filter sobel.

Abstract

MONANG ANTONIUS PURBA. 2020. THE EFFECT OF GOAT DIRTY ON THE VEGETATIVE GROWTH OF OIL PALM BIBT (Elaeis guineensis jacq) IN PRE NURSERY USING HYDROPONIC METHOD. Final Project of STIPAP Student of Plantation Cultivation Program. This research was supervised by Mr. Aulia Juannda Djs, S.Si., M.Si and Mrs. Ingrid Ovie. Y. Sitompul. This research was conducted in the STIPAP MEDAN greenhouse. When this research was conducted in April - July 2020. This study used the Hydroponic Method and used a completely randomized design as data processing. This research was conducted to determine the development of oil palm seedlings every 2 weeks. The vegetative growth of oil palm (Elaeis guineensis Jacq) in the pre-nursery using the hydroponic method using goat manure has no significant effect on most of the parameters observed except for plant height which has a significant effect. From the average observation of the effect of goat manure on the vegetative growth of oil palm seedlings (Elaeis guineensis Jacq) in the pre-nursery using the hydroponic method, it can be seen that the highest effect obtained is on the 2500ppm treatment, namely on plant height (19.85 cm), stem girth. (2.63 cm), and the number of leaves (3.31 cm). Meanwhile, the average yield of leaf chlorophyll and leaf width obtained the best results from the 1500ppm treatment, namely 24.99 cm stem girth and 3.39 cm leaf width. The conclusion that can be drawn from the results of this study is that the dose at the 2500ppm treatment is right for use in the hydroponic method and it is hoped that this research can be developed by looking for other organic fertilizers to be combined with goat manure with the best dose, so that the nutrient content that has been added is more complete. there is. And continued research was carried out at the Main Nursery (MN).
