Abstract

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%).

Abstract

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

Abstract

Rendahnya mutu bahan olah karet rakyat (bokar) antara lain disebabkan rendahnya penanganan pasca panen, seperti wadah penampung lateks yang sembarangan, penggumpal lateks yang tidak bermutu, dan belum memenuhi syarat. Faktor penampung lateks dan bahan penggumpal dinilai sebagai faktor utama penyebabnya. Untuk mengatasinya, perlu dilakukan penelitian yang berhubungan dengan penampung lateks, bahan penggumpal, dan teknik penanganan bokar. Penelitian ini bertujuan untuk mengatasi mutu bokar yang rendah. Penelitian dilakukan pada kebun karet rakyat di desa Sari Laba Jahe (Kecamatan Sibirubiru, Deli Serdang, Sumatra Utara). Desa tersebut merupakan penghasil asam gelugur dan nanas. Penelitian dilakukan dengan menguji 3 jenis penampung lateks (penampung lateks standar, ruas bambu, dan tempurung kelapa), dan empat jenis bahan penggumpal (ekstrak asam gelugur, ekstrak nanas, asam semut, dan pupuk TSP). Kombinasi dari kedua bahan tersebut diulang sebanyak 3 kali. Hasil dalam bentuk bokar kemudian dijepit pada media anyaman bambu, masing-masing selama 2, 4, dan 6 hari. Pengamatan meliputi berat bokar dan kadar karet kering (KKK). Hasil penelitian menunjukkan bahwa penampung lateks standar merupakan penampung lateks terbaik untuk menghasilkan berat bokar tertinggi. Sedangkan penggumpal ekstrak asam gelugur dan ekstrak nanas dengan masa penyimpanan 6 hari menghasilkan bokar dengan KKK tertinggi, yakni > 70%.
