Penyediaan benih bermutu dipengaruhi oleh penyimpanan benih. Lama simpan dan suhu ruang menjadi faktor utama yang menyebabkan kemunduran benih dan vigor benih. Suhu penyimpanan dapat mempengaruhi metabolisme benih yang juga berkaitan dengan kelembaban nisbi ruang simpan dan kadar air benih. Metabolismeyang tinggi selama penyimpanan berakibat pada kemunduran benih dan vigor benih. Penelitian ini bertujuan untuk mengetahui kemunduran dan vigor benih sorgum varietas Samurai-1 yang disimpan pada suhu ruang 18 ±1,58ºC dan 26 ±1,08ºC. Penelitian ini dilaksanakan di Laboratorium Benih dan Pemuliaan Tanaman, Fakultas Pertanian Universitas Lampung dari Febuari 2017 sampai dengan Febuari 2018. Perlakuan disusun secara faktorial dengan strip plot 2x4 dalam 3 ulangan teracak lengkap. Petak utama yaitu suhu ruang simpan (T) yang terdiri dari 2 taraf yaitu suhu ruang simpan 18 ±1,58ºC (T1) dan suhu ruang simpan 26 ±1,08ºC (T2). Anak petak yaitu lama penyimpanan (L) yang terdiri dari 4 taraf yaitu 0 bulan (L1), 4 bulan (L2), 8 bulan L3), dan 12 bulan (L4). Pengaruh antar perlakuan dilihat dengan analisis ragam pembandingan nilai tengah perlakuan menggunakan uji Beda Nyata Jujur (BNJ) masing-masing pada taraf nyata 5%.Hasil penelitian menunjukkan bahwa benih dengansuhu ruang simpan 18 ±1,58ºC dan 26 ±1,08ºC tidak menyebabkan perbedaan vigor dan kemunduran benih pada lama simpan 0, 4, 8, dan 12 bulan. Lama simpan 4, 8, dan 12 bulan menyebabkan kemunduran dan vigor benih lebih rendah dibandingkan dengan yang belum disimpan ( 0 bulan), yang ditunjukkan oleh daya hantar listrik, kecambah normal total, kecepatan perkecambahan dan benih mati.
There is a long historical timeline before the idiom of fintech becomes something as popular as we know today. Fintech includes any novelty innovation on any given space at any given time if it is considered to be revolutionary or disruptive enough to change the activities in the financial sector. This article will describe the evolutionary process of fintech from the perspectival approach of "trends" that financial regulators use to encounter incoming novelty innovations. The regulatory approach is a more tangible measurement tool because just like animals will adapt to environmental changes, regulators will also adjust to upcoming innovations. The transitional shift from the brick and mortar Laissez-Faire paradigm to the adaptation of various Piloting Projects and Regulatory Sandboxes across the globe are concrete shreds of evidence that regulatory approach can be used as a standard perimeter to determine and measure the developmental milestones of Fintech History
Effect of Immersion Time in Various Concentrations Gibberellins (GA3) on Oil Palm Seed Germination (Elaeis guineensis Jacq.
Growth and yield of oil palm is largely determined by climatic conditions especially in the dry season. The purpose of this study was to determine the effect of planting date and irrigation in the dry season of 2015 on the growth and production of palm oil in 2016. The data collecting was conducted from June to October 2016 at a plantation company, Southern Lampung. Treatments were arranged by factorial (3x2) in randomized block design with 7 replications. The first factor was age categories consisted of mature trees planted 2001 (TD 2001), young trees planted 2009 (TM 2009), and young trees planted 2010 (TM 2010). The second factor was irrigation (no irrigation and with irrigation). The irrigation used was bulk irrigation with rotation of once in a weeks during dry season (September-October). Observed variables were number of broken frond, spear frond, dried frond, female inflorencence, and bunches yield. Data was analyzed by analysis of the variance (ANOVA), and the differences of the mean were analyzed by Tuckey at 5% level of significant difference. Irrigation decreased number of broken frond and dry frond. Irrigation increased fresh fruit bunch yield of certain months in current and next year. Age categories (young and mature) had no signicantly effect on number of bunch and fresh fruit bunch per tree. However there was interaction between age categories and irrigation on the average of bunch weight. Keywords : growth, oil palm, rainfall, water deficit, yield
Selain sebagai bahan pangan dan pakan, sorgum berpotensi menghasilkan nira untuk bioethanol. Beragamnya potensi hasil nira, mendorong perlunya evaluasi keragaan berbagai genotip sorgum untuk digunakan sebagai kriteria seleksi. Penelitian ini bertujuan untuk mengevaluasi produksi nira, membandingkan keragaman genetik dan fenotip pada beberapa genotip sorgum, serta menghitung heritabilitas arti luas. Penelitian dilaksanakan di Desa Sukanegara, Kecamatan Tanjung Bintang, Kabupaten Lampung Selatan dari April 2017 sampai Februari 2018. Rancangan perlakuan disusun secara strip plot dalam Rancangan Acak Kelompok Lengkap dengan tiga ulangan yang digunakan sebagai kelompok. Kondisi tumpangsari dan monokultur yang digunakan sebagai pembanding disusun secara strip plot. Sebanyak 15 genotip digunakan, yaitu GH 3, GH 4, GH 5, GH 6, GH 7, GH 13, Super 1, Super 2, Samurai 1, UPCA, Numbu, Mandau, Talaga Bodas, P/IWHP, dan P/F 5-193-C. Hasil penelitian menunjukkan bahwa genotip Talaga Bodas mempunyai kandungan nira yang cukup tinggi baik pada kondisi tumpangsari maupun monokultur yang masing-masing sebesar 144,0 ml dan 166,0 ml. Sementara genotip Super 1 menunjukkan kandungan nira paling tinggi pada kondisi tumpangsari (163,0 ml) dan genotip GH13 menghasilkan volume nira paling tinggi pada sistem monokultur (183,0 ml). Nilai heritabilitas arti luas pada tinggi tanaman, nilai brix, kandungan nira, dan jumlah ruas pada sistem tanam tumpangsari dan monokultur termasuk dalam kriteria tinggi (0,6-0,9). Nilai heritabilitas yang tinggi pada karakter tersebut menunjukkan bahwa faktor genetik lebih berpengaruh sehingga bisa digunakan sebagai kriteria seleksi.ABSTRACT In addition to foodstuffs and feed, sorghum potentially produces “nira” for bioethanol. The varying potency of the nira results, prompting the need to evaluate the performance of various sorghum genotypes for use as selection criteria. The objectives of this study were to evaluate nira production, to compare genetics and phenotype variances of sorghum genotypes, also to calculate broad sense heritability of some sorghum genotypes. This study was conducted at Desa Sukanegara, Kecamatan Tanjung Bintang, Kabupaten Lampung Selatan from April 2017 to February 2018. The experiment was designed by stripe plot in completely randomized block design with three replications used as block. The conditions of monoculture and intercropping used as comparison were arranged in stripe plot. As many as 15 genotypes used in this study i.e. GH 3, GH 4, GH 5, GH 6, GH 7, GH 13, Super 1, Super 2, Samurai 1, UPCA, Numbu, Mandau, Talaga Bodas, P/IWHP, and P/F 5-193-C. The result showed that Talaga Bodas genotype had high volume of nira content under monoculture and intercropping conditions as 144.0 ml and 166.0 ml, respectively. However, Super 1 genotype had high nira content (163.0 ml) under intercropping condition and GH13 genotype had high nira content under monoculture (183.0 ml). Broad sense heritability of plant height, brix value, nira content, and internode number in both intercropping and monoculture conditions was high (0.60 – 0.90). These high heritability values mean that these characters are influenced by genetics factor and could be used as selection criteria.
