Penelitian ini dilakukan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan Kolam No. 1 Medan Estate, Kecamatan Percut Sei Tuan. Penelitian ini dilaksanakan mulai bulan April 2012 sampai Juli 2012. Tujuan penelitian untuk mengkaji pertumbuhan dan produksi tanaman cabai merah pada berbagai jenis bahan kompos sebagai media tumbuh di polibag. Penelitian dilaksanakan dengan menggunakan Rancangan Acak Kelompok (RAK) non faktorial terdiri dari 5 taraf perlakuan yaitu : K0 = Cara konvensional (Urea, TSP. KCl masing-masing 3 g/polibeg), K1 = Kompos daun (50 g/polibag), K2 = Pupuk kandang sapi (25 g/polibag), K3 = Pupuk kandang ayam (12,5 g/polibag), dan K4 = Pupuk kandang kambing (25 g/polibag). Parameter yang diamati adalah tinggi tanaman, jumlah cabang produktif, jumlah buah per tanaman, intensitas serangan hama, dan inventarisasi hama. Hasil penelitian menunjukkan bahwa pnggunaan berbagai jenis bahan kompos sebagai media tumbuh dapat meningkatkan pertumbuhan dan produksi tanaman cabai merah, dimana perlakuan terbaik adalah kompos daun, kemudian diikuti pupuk kandang sapi, pupuk kandang ayam, pupuk kandang kambing dan secara konvensional. Intensitas serangan hama lebih kecil dengan menggunakan media kompos daun dan pupuk kandang sapi, dan intensitas serangan paling tinggi ditemukan pada perlakuan konvensional.
Banana cultivation will not be separated from pest problems. One of the main pests that attack banana plants is the banana leaf rolling caterpillar Erionota thrax L. The research was carried out in the Unified Community Farmer Group of Sampali Village, Percut Sei Tuan District, Deli Serdang Regency in March-May 2020. The research method used was descriptive analysis method using random sample (random sampling). The observation parameters consisted of population density, level of pest attack, egg parasitoid, larval parasitoid, pupa parasitoid, parasitoid identification, species diversity index, species evenness index, and relative abundance. There are 4 types of parasitoids, namely Braconidae sp 1 (Hymenoptera: Braconidae), Tachinidae sp 1 (Diptera: Tachinidae), Xanthopimpla gampsura (Hymenoptera: Ichneumonidae) and Brachymeria lasus Walker (Hymenoptera: Chalcididae). Erionota thrax L. parasitoid diversity index 0.7929 in low diversity levels, and the highest relative abundance of Brachymeria lasus Walker 98%, Erionota thrax attack rates on Barangan bananas reached 36.51%, Erionota thrax attack rates on Kepok bananas reached 45.13% , the attack rate of Erionota trax on Roti bananas was 50.72%, while the attack rate of Erionota thrax on FHIA-17 bananas was 42.46%.
Sampali Village is an agricultural area that is very suitable for banana planting. Various types of bananas found in the village include Barangan, Kepok, Molen, Raja and banana Nangka . Banana shoots from harvested mother plants are used for development in new areas. Banana seedlings from the suckers appear healthy, but often these suckers die after 1-2 months of planting in new areas. This is because these bananas have been infected with fungal pathogen wilt caused by Fusarium oxysporm f. sp cubense and Ralstonia syzygii subsp. celebesensis causes of blood diseases. Both of these pathogens are the main cause of the low quality of banana seeds. The use of low-quality banana seedlings (sapling sources), high pest and disease attacks are the factors causing the reduced amount of banana planting land which results in low banana production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. Banana farmer groups in the village of Sampali have never used and planted banana seedlings that were propagated by tissue culture. The objectives of the activity were: 1. Socialization and practice of propagation of banana seedlings from sucker . Mycorrhizal inoculant application when planting seedlings in a polybag. To increase the knowledge of farmer group members and also the students of Agricukture Faculty,Universitas Medan Area the learning of banana propagation techniques is carried out in vitro at the Balai Benih Induk Hortikultura, Gedung Johor Medan . The method used to solve the above problems is the provision of material, the practice of making banana seedlings through the propagation of tillers and a visit to the Balai Benih Induk Hortikultura, Gedung Johor Medan. At the end of the activity, an increase in the knowledge and skills of participants in providing quality banana seeds is the source of banana propagation in the village Sampali
Ripe banana peroxidase activities with Glomus type 1. Ripe banana is very susceptible to blood disease caused by Blood disease bacterium (BDB) and Fusarium wilt caused by Fusarium oxysporum f.sp. cubense. Arbuscular mycorrhizal fungi (AMF) Glomus tipe 1 increased resistance of ripe banana seedlings to both wilt diseases. The resistance mechanism related with the change of hydrolytic enzyme activities: peroxidase (PO), phenylalanin amonialyase (PAL) and polyphenoloksidase (PPO). The green house and laboratorium experiment were conducted to study the effect of different colonization time 4, 12, 24, 36, 48, 72, 96 h after application (haa) and control (without AMF) with 3 replicates. AMF fresh inoculants source is a mixture of sand planting medium that containing spores, hyphae and corn root colonized AMF. Ripe banana seedlings (60 days old) were inoculated with 50 g fresh AMF inoculants and incubated with the treatment. The results showed that the application of Glomus tipe 1 caused changes in the enzyme activity of peroxidase in the roots and leaves. Root peroxidase enzyme activity slightly increased 5.84% (0.326U) at the beginning of colonization (4 haa) while peroxidase enzyme activity in leaves sharply declined (85.83-87.37%).Key words: arbuscular mycorrhizal fungi, blood disease bacterium, Fusarium oxysporum f.sp. cubense, Glomus tipe 1, peroxidase enzyme activities, ripe banana ABSTRAKAktivitas enzim peroksidase pisang kepok dengan aplikasi Glomus tipe 1. Tanaman pisang kepok sangat rentan terhadap penyakit layu bakteri yang disebabkan oleh Blood Disease Bacterium (BDB) dan layu Fusarium oleh Fusarium oxysporum f.sp. cubense (Foc). Aplikasi Glomus tipe 1 mampu meningkatkan ketahanan tanaman pisang kepok terhadap kedua penyakit tersebut. Peningkatan ketahanan tanaman pisang tersebut berkaitan erat dengan perubahan aktivitas enzim hidrolitik seperti peroksidase (PO), phenylalanin amonialyase (PAL) dan polypeniloksidase (PPO). Tujuan penelitian adalah mengukur aktivitas enzim peroksidase dan kadar protein tanaman pisang kepok setelah aplikasi Glomus tipe 1. Sebanyak 50 g inokulan Glomus tipe 1 diaplikasi pada perakaran bibit pisang kepok umur 2 bulan setelah aklimatisasi. Kolonisasi mikoriza pada perakaran bibit pisang Kepok disesuaikan dengan perlakuan waktu kolonisasi yaitu 4, 12, 24, 36, 48, 72, 96 jam setelah aplikasi (jsa) dan kontrol (tanpa mikoriza). Parameter yang diamati adalah aktivitas enzim peroksidase dan kadar protein tanaman pisang kepok dengan metode Lowry. Hasil penelitian menunjukkan bahwa aplikasi Glomus tipe 1 menyebabkan perubahan aktivitas enzim peroksidase dalam akar dan daun. Aktivitas enzim peroksidase akar sedikit meningkat 5,84% (0,326U) pada awal kolonisasi (4 jsa) sementara aktivitas enzim peroksidase dalam daun mengalami penurunan yang tajam (85,83-87,37%) .
Growth of FHIA-17 Banana Seedlings with the Application of Hijauan Paitan Fertilizer (Titonia Diversifolia) and Cow Manure. The aim of this study was to obtain data on the growth of FHIA-17 banana seedlings after application of T.diversifolia forage and cow manure. Using a factorial Randomized Block Design (CRD) with two treatment factors. The first factor is the forage dose of T. diversifolia (P) with 5 levels, P0=Control; P1=12.5 g kg-1 planting medium (equivalent to 5 tons ha-1); P2=25 g kg-1 planting medium (equivalent to 10 tons ha-1); P3=37.5 g / kg of planting media (equivalent to 15 tons ha-1); P4=50 g kg-1 of growing media (equivalent to 20 tons ha-1). The second factor is the dose of cow manure (K) with 5 treatment levels namely, K0=Control; P1=12.5 g kg-1 of growing media (equivalent to 5 tons ha-1); K2=25 g kg-1 of growing media (equivalent to 10 tons ha-1); K3= 37.5 g kg-1 of growing media (equivalent to 15 tons ha-1); K4=50 g kg-1 planting medium (equivalent to 20 tons ha-1 and repeated 2 (two) times. Observed parameters were plant height (cm), number of leaves, stem circumference (mm), plant wet weight (g), plant dry weight (g). The results of this study indicate that the application of forage T. diversifolia significantly affected plant height and number of leaves. It’s not real with respect to all observational parameters.
