Abstract

Banana is one of the most important global agriculture commodities. Asia accounts for the production of bananas amounted to 56.4% of total banana in the world and Indonesia is one of the banana-producing countries in Asia. The demand for bananas increased need is anticipated with good cultivation techniques to meet domestic and international market demand. Plant regeneration in vitro tissue culture techniques or can be used to produce propagules true-to-type in large quantities in a relatively short period and free from disease. This research aims to study the influence of various concentrations of BA (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 mg/l) against the growth and reproduction of Cavendish banana propagules in vitro. Time appears buds, propagules length and the number of propagules per explant, and the number of primary roots of plants per explant observed after eight weeks of culture. The experiment results show that after explant grown for eight weeks on the media's treatment shows the different response. The increased concentration of BA can increase the number of shoots. The increased concentration of BA from 0.5 mg/l be 1-3 mg/l increased the number of propagules, but the number of propagules will decrease in the concentration of BA more 3.5 or 4 mg/l. In addition to BA concentration 0.5, 1 and 1.5 mg/l MS media into producing shoot buds appear faster time high, highest propagules and root amount more on banana propagules Cavendish, but the number of shoots is fewer. The best of BA concentrations to induce propagules plant bananas Cavendish is 3.0 mg/l.

Abstract

The purpose of this study was to determine the characteristics of the micro-climate(temperature, humidity, and light intensity) and the production of sweet corn on a sigle row,doble row, twin row, and Twin seed planting system. This study was conducted in anexperimental garden of Politeknik Negeri Lampung, Hajimena South Lampung, in July-September, 2015. This study is based on randomized block design with one factor croppingsystem consists of 4 treatment ie : Sigle Row (SR) (20cm x 75cm), Doble Row ( DR ) (20cm x20cm x 80 cm), Twin Row (TR) (20cm x 10cm x 80 cm) , and Twin Seed (TS) with plantSpacing (40cm x 75cm 2 seed in one planting hole). Parameter observations of this studyconsisted of (1) micro-climate (temperature (oC), relative humidity (RH %) and Interceptionof Light (%) ) and (2)production (corn length (cm) , corn diameter (m ) and Corn weights(grams). The data were analyzed using the F test at 1 % and 5 % level and than followed bytest BNT. The conclusion of this study were (1) The characteristics of the microclimate : a)There is a noticeable difference in the temperature of the top of the current crop of 4 mst andat 9 mst there is a significant difference in the temperature of the bottom , where SR has adifferent temperature involves the other b) All systems planting has a relative humidity (%)were not significantly different , and c ) there is a difference light interception ( % ) duringthe day when 4 mst , where the twins seed has a light interception is different from othertreatments and there is a difference light interception during 9 mst where sigle row has adifferent light interception to other treatments. (2) The production of sweet corn on thetreatment SR, DR, TR and TS were not significantly different and has a weight of corn (SR =354.8 grams, DR = 316.5 grams, 328.5 grams TR and TS = 325.4 grams) same withdescription bonanza varieties (270-300 grams).Keywords : Cropping Systems , Micro Climate , Production

Abstract

Aklimatisasi merupakan tahap yang kritis bagi plantlet. Pada lingkungan yang baru plantlet dapat mengalami cekaman lingkungan. Kondisi lingkungan seperti media yang tidak mendukung pada tahap aklimatisasi dapat menyebabkan kematian plantlet.  Penelitian ini bertujuan:  1)  Mendapatkan kombinasi  media yang paling baik bagi keberhasilan aklimatisasi plantlet anggrek Phalaenopsis; 2)Mengetahui apakah terdapat interaksi antara media bagian bawah dengan atas pot; 3) Mendapatkan kombinasi media yang paling baik bagi pertumbuhan bibit anggrek anggrek Phalaenopsis pada tahap pembesaran, dan 4) Melihat apakah media sabut kelapa dapat digunakan untuk aklimatisasi dan pembesaran anggrek Phalaenopsis.  Penelitian dilaksanakan di rumah jaring Politeknik Negeri Lampung dari bulan Maret hingga Agustus 2018.  Plantlet diaklimatisasikan 4 minggu.  Percobaan faktorial dilaksanakan dalam rancangan acak kelompok. Faktor A :  macam media bagian bawah (bata/arang).  Faktor B :  macam media bagian atas (moss sphagnum/pakis/sabut kelapa).  Enam kombinasi perlakuan dicobakan (masing-masing dengan 10 ulangan), yaitu:   P1 (bata+moss); P2 (bata+pakis); P3 (bata+sabut kelapa); P4 (arang+moss); P5 (arang+pakis); dan P6 (arang+sabut kelapa).  Peubah yang diamati: 1)  persen keberhasilan plantlet menjadi bibit, 2) tinggi bibit, 3) panjang daun, 4) lebar daun, dan 5) jumlah daun.   Data yang diperoleh dilakukan analisis ragam dan dilanjutkan dengan uji BNJ 5%.  Hasil penelitian menunjukkan: 1) Media moss atau pakis dikombinasikan dengan bata maupun arang memberikan persen keberhasilan aklimatisasi plantlet anggrek Phalaenopsis yang paling baik (100%); 2) Tidak terdapat interaksi antara media bagian atas dengan bagian bawah; 3) Kombinasi media yang paling baik bagi pertumbuhan bibit anggrek Phalaenopsis pada tahap pembesaran adalah moss baik dikombinasikan dengan bata ataupun arang, kemudian diikuti oleh pakis (dikombinasikan dengan bata ataupun arang); dan 4) Media sabut kelapa dapat digunakan untuk aklimatisasi dan pembesaran bibit anggrek Phalaenopsis bila  dilakukan penyiraman yang lebih intensif.
