<p class="8AbstrakBahasaIndonesia">Rendahnya produktivitas kopi Indonesia di akibatkan oleh kebun pertanaman yang telah tua serta belum dimanfaatkannya bahan tanam unggul, untuk itu perlu dilakukan kajian tentang penggunaan bibit unggul yang yang relatif mudah dan praktis yaitu dengan cara stek daun.Penelitian tentang Studi Sumber Stek yang berbeda dan pemberian Rootone F Terhadap Tingkat keberhasilan Stek Daun Kopi (Coffea Canephora Pierreex Froehner) telah dilaksanakan di kebun percobaan Universitas Medan Area yang dimulai dari bulan Februari sampai dengan april 2013. Tujuan penelitian ini adalah untuk mengetahui sumber stek daun yang berbeda dan Konsentrasi zat pengatur tumbuh terbaik untuk pertumbuhan setek daun kopi. Percobaan ini menggunakan Rancangan Acak Lengkap (RAL) dengan 12 taraf perlakuan dengan 3 ulangan. Data hasil percobaan ini dianalisis secara statistika dengan uji F pada taraf nyata 5% dan F perlakuan yang berbeda nyata dilanjutkan dengan uji lanjutan jarak Duntcunt ada taraf nyata 5%. Hasil penelitian ini menunjukkan sumbertek yang berbeda memberikan pengaruh yang nyata untuk parameter persentase tumbuh dan persentase hidup, sumber stek bagian ujung lebih baik di banding dengan sumber stek bagian tengah dan bagian pangkal untuk parameter pertentase stek hidup, sedangkan untuk parameter persentase tumbuh menunjukan sumber stek bagian pangkal lebih baik dibanding dengan sumber stek bagian ujung dan bagian tengah.</p>
This study aims to determine the effect of different concentrations of liquid fertilizer with hydroponic planting media on kale production. The research method used was Randomized Completely Factorial Design with 2 factors: POC cocoa skin and cocoa poc added with cow dung. This study consisted of 16 treatment combinations each repeated 2 times. So there are 32 units of the whole experiment. Parameters observed include: percentage of growth, plant height, number of leaves (leaf), leaf area (), measuring leaf color, wet weight of harvest, wet weighted weighing, root length measurement. Based on the results of research that has been carried out can be concluded as follows: Provision of liquid organic fertilizer from cocoa leather and organic fertilizer liquid cow dung on the growth and production of kale plants showed unequal generative growth. The dosage of liquid organic fertilizer (POC) given by kangkung plantation has no effect on the increase of observed parameters from plant height, leaf number, leaf color, leaf area, and wet weight of the plant. In the excess of nutrient elements
Radopholus similis adalah salah satu faktor pembatas utama produksi pisang di dunia termasuk Indonesia dan petani selalu mengandalkan nematisida untuk mengelola kehilangan hasil. Penggunaan cendawan endofit merupakan salah satu metode yang dapat mengurangi kebutuhan nematisida, tetapi sedikit sekali informasi tentang metode aplikasi cendawan endofit yang efektif untuk mengendalikan R. similis. Penelitian ini bertujuan untuk mendapatkan metode aplikasi cendawan endofit yang efektif untuk menekan populasi R. similis pada tanaman pisang. Lima belas cendawan endofit yang diisolasi dari akar dan bonggol pisang dari beberapa pertanaman pisang di Sumatera Utara diaplikasikan pada pisang Barangan dengan metode tabur dan rendam. Isolat cendawan endofit terdiri atas 11 isolat Fusarium sp. (2BSTMHMM, 3ASTMHP, 5ASP, 1ASU, 4BSP, 4BJP, 5BKJP, 4BSU, 1BJP, 2 BSP, dan 4BKJP) dan 4 isolat Trichoderma sp. (2BSTMHP, 4BSTMHP, 2BSPH, dan 2BSTMHH). Hasil penelitian menunjukan bahwa 15 isolat cendawan endofit tersebut mampu menekan populasi R. similis dan memiliki potensi meningkatkan pertumbuhan tanaman.
The research objective was to determine the use of Trichoderma sp. to control shallots tuber (Allium ascalonicum L.). The research was conducted at Growth Center, Jl. Peradilan Tata Usaha Negara No. 1 Kenangan Baru, Percut Sei Tuan District, Deli Serdang Regency, 25 meters above sea level (asl). The design used was a factorial randomized block design (RBD) consisting of 2 factors, namely the factors of administration of Trichoderma sp. Consists of 5 levels, namely: T0: Control (without Trichoderma sp.), T1: 10 g Trichoderma sp./polybag, T2: 20 g Trichoderma sp./polybag, T3: 30 g Trichoderma sp./polybag, T4: 40 g Trichoderma sp./polybag. and time of giving Trichoderma sp. Consists 2 levels, namely: W1: Trichoderma sp. given 1 week before planting, and W2: 1 week after planting with 10 treatments combination. Observations included plant height (cm), number of leaves per clump (strands), number of tillers per clump (tuber), tuber wet weight per sample (g), tuber dry weight per sample (g), and the percentage of tuber rot attack. The results showed that: 1). The use of Trichoderma sp. with various doses (T0, T1, T2, T3, and T4) significant effect on plant height but no effect on observed other. While application time of Trichoderma sp. 1 week after planting (W2) showed a significant effect on plant height, number of leaves, number of tillers. also significantly affected wet weight, dry weight, and the percentage of tuber rot attack. 2). The combination of the two treatment factors had no significant effect on all observed parameters.
Coffee (Coffea spp) is mostly useful as a beverage is not foreign not only for the nation of Indonesia, but also for various nations in the world. One way to increase yields and extend the life of coffee plants is by pruning. From the results of this pruning of course produces quite a lot of leaves are wasted, so it takes science and technology cultivation of coffee plants by utilizing the coffee leaves. In this study will discuss about the Study of Coffee Plant Propagation (Coffea spp) With Leaf Cut. The research was conducted in March - June 2011 in Galang Suka Village, Galang Subdistrict, Deli Serdang Regency. This research was conducted by Randomized Complete Design (RAL) Factorial with two factors. The first factor is a coffee leaf (D) consisting of two levels of treatment. D1 = The base of the leaf without the petiole, D2 = Leaf tip. The second factor is Nutrition (N) which consists of six levels of treatment. N0 = Rotone-F 200 mg / l, N3 = Growtone 200 mg / l, N4 = Growtone 300 mg / l, N5 = Dekamon 2 cc / 10 liters. From the results of the study it can be concluded that leaf tip (D2) cuttings given Growtone 200 mg / l (N3D2) survive until the end of the study, as well as leaf tip (D2) cuttings given Dekamon 2cc / 10 l (N5D2) although the numbers are only 1.23 and 1.06 and N3D2 is better than N5D2.
