Penelitian ini bertujuan untuk mengetahui pengaruh asal stek dan zat pengatur tumbuh Atonik terhadap pertumbuhan dan produksi dua varietas ubi jalar. Penelitian ini dilaksanakan di lahan masyarakat bajak V, kelurahan Harjosari II kecamatan Medan Amplas, Sumatera Utara, Medan, dengan ketinggian tempat +33 m dpl, dilaksanakan pada bulan September 2015 sampai Januari 2016 menggunakan Rancangan Acak Kelompok dengan tiga faktor perlakuan yaitu varietas (Antin-1 dan Kidal), bahan asal stek (stek pucuk dan stek pangkal) dan zat pengatur tumbuh Atonik (0,25 ml dan 0,50 ml). Peubah amatan yang diamati adalah pertambahan panjang tanaman, jumlah umbi per sampel, panjang umbi per sampel, diameter umbi per sampel, bobot umbi per sampel, bobot umbi per plot dan uji organoleptik. Hasil penelitian menunjukkan bahwa varietas berbeda nyata terhadap pertambahan panjang tanaman, jumlah umbi per sampel, panjang umbi per sampel, diameter umbi per sampel, bobot umbi per sampel, bobot umbi per plot. Stek berbeda nyata terhadap pertambahan panjang tanaman, Interaksi antara varietas, stek, dan Zat pengatur tumbuh Atonik tidak berpengaruh nyata.

Induksi Kalus Tanaman Rosella (Hibiscus sabdariffa Linn.) pada Jenis Eksplan dan Konsentrasi Auksin yang Berbeda Suci Khairani Safitri; Luthfi A. M. Siregar; Khairunnisa Lubis

Penelitian ini bertujuan untuk mengetahui produksi biomassa kalus dari induksi kalus pada jenis eksplan tanaman rosela (Hibiscus sabdariffa Linn.) dan konsentrasi auksin yang berbeda di dalam media MS dibimbing oleh Luthfi A. M. Siregar dan Khairunnisa Lubis. Penelitian ini dilakukan di Laboratorium Kultur Jaringan UPT. Benih Induk Hortikultura Gedung Johor Medan dan Laboratorium Analisis Kimia Bahan Pangan FP-USU, Sumatera Utara, Indonesia, pada mulai Mei sampai dengan Juni 2016. Penelitian ini menggunakan rancangan acak lengkap dengan dua faktor, yaitu: jenis eksplan, terdiri dari 3 tingkatan: daun, tangkai daun dan batang, dan media terdiri dari enam komposisi; MS + 0 mg / l NAA + 1,5 mg / l BAP; MS + 1 mg / l NAA + 1,5 mg / l BAP; MS + 2 mg / l NAA + 1,5 mg / l BAP; MS + 3 mg / l NAA + 1,5 mg / l BAP; MS + 4 mg / l NAA + 1,5 mg / l BAP; MS + 5 mg / l NAA + 1,5 mg / l BAP. Hasil penelitian menunjukkan bahwa eksplan daun menunjukkan kalus yang terbaik dan media MS + 5 mg / l NAA + 1,5 mg / l BAP memberi biomassa kalus yang terbaik. Interaksi eksplan dan media dengan kombinasi zat pengatur tumbuh memberi persentase terbentuknya kalus. Media MS + 4 mg/l NAA + 1,5 mg/l BAP ; MS + 5 mg/l NAA + 1,5 mg/l BAP adalah media terbaik untuk terbentuknya kalus.

Growth Test of Varieties of Palm Oil (Elaeis guineensis Jacq.) Seedlings with Hydroponic in Pre Nursery Arung Buana; Rosmayati Rosmayati; Khairunnisa Lubis

The aim of this research was to test the growth of palm oil varieties seedlings with some concentration of nutrients. This research was conducted at Greenhouse Faculty of Agriculture University of Sumatera Utara, from August to October 2017. The research design used randomized block design (RBD) with 2 factors. The first factor was varieties consist of 3 varieties namely DxP Avros, DxP Langkat, and DxP Yangambi. The second factor is the concentration consisting of 4 levels (8 HS, 1 HS, 1,2 HS and 1,4 HS). The observed variables were plant height (6, 8, 10, and 12 weeks after planting), number of leaves, stem diameter, root number and root length. The results showed that varieties significantly different to the plant height, stem diameter, and root length. The different concentration of nutrients had no significantly effect to all observed variables, and there was no interaction between the two treatments. 6 observed variables had high heritability at plant height 6, 10, and 12 weeks after planting, number of leaves 8 weeks after planting, stem diameter, and root length characters.

Penampilan Morfologi Akar Beberapa Hasil Persilangan (F1) Tanaman Jagung Pada Media Tanam Tanah Gambut Dengan Penambahan Bahan Organik Leguminosa Di Rhizotron Wita Purwasih; Khairunnisa lubis; Eva Sartini Bayu

The maize in indonesia mostly use land that is not fertile. The objective of the research was identified the selection character based on root morphology of hybrid maize (F1) in peat soil medium applicated with legume organic manure in rhizotron. The research was conducted at the greenhouse of Faculty of Agriculture, University of Sumatera Utara, from February until July 2017. The Randomized Block Design was used with two factors, the first factor is the population (V1, V2, V3, V4, V5) and the second factor is the planting medium (peat soil, peat soil + leucena, peat soil + mucuna). The parameters observed were: the number of root, the length of root, the diameter of root dispersed, the fresh weight of the canopy, the fresh weight of root and the dry weight of root. The result showed that the population F1 significantly affected the number of root, the volume of root, the fresh weight of root and the dry weight of root. The planting medium significantly affected the number of root, the length of root, the diameter of root dispersed, the volume of root, the fresh weight of the canopy, the fresh weight of root, the dry weight of root. Interaction between the population F1 NEI9008 x CLA46 (V5) and the planting medium peat soil + mucuna significantly affected the fresh weight of root. Keywords : maize, legume organic manure, peat soil, root morphology, rhizotron

Performance of Vegetative and Reproductive Characteristics of Multiple Outcomes (F1) of Maize (Zea mays L.) on Peat Soil applied Sludge and Ash of Oil Palm sulthan sulaiman siddik; khairunnisa lubis; hot setiado

Maize is one of the staple food crops in Indonesian that must be developed its genetic diversity. The objective of this study was to obtain the appearance of vegetative and reproductive character of some F1 maize populations on peat soil stress with pH criteria of 5.9 and peat soil with sludge and ash of oil palm. The research was conducted at Setiabudi field, Tanjung Rejo sub-district, Medan city from April to August 2017. This research used Randomized Block Design (RAK) with 2 treatment factors. The first factor is the population consisting of 5 levels:A (NEI9008 x CLA46), B: (NEI9008 x CLA106), C: (CLA106 x NEI9008),D: (CLA16 x CLA84), E: (CLA84 x NEI9008) and the second factor is planting medium consisting of 3 levels is M1 (peat soil), M2 (peat soil + ash of oil palm), M3 (peat soil + sludge). The results showed that the interaction of planting media with F1 population of maize plant had significant effect on plant height character. The best media is found in M3 (peat soil + sludge).
