Jurnal Penelitian Pertanian Terapan is a peer-reviewed journal that publishes scientific articles from agricultural disciplines covering Plantation crops, Food crops and horticulture, food Technology, Agriculture biology and agribusiness. Articles published in the Journal of Applied Agriculture may be research results (original) and scientific review articles (review). Applied Journal of Agriculture is published by Research Unit and Community Service of Lampung State Polytechnic Society 3 edition one year, that is January, May, and September. JPPT was first published in January 2000. JPPT published a print version in 2007, then started the online version or Open Journal System (OJS) in 2014. Early online versions of JPPT or OJS editing have not yet been fully implemented online management and are beginning to make improvements Web Journal view and journal cover and OJS governance management on Volume 2 No. 2 of 2017. JPPT has been indexed on Google Scholar and Garuda IPI by 2015, and by 2017 it has indexed SINTA and registered DOAJ and Crossref in the same year. We accept submissions from all over Indonesia. All submitted articles will not be published elsewhere, original and not considered for other publications.

Abstract

Penelitian telah dilaksanakan di PT Nusantara Tropocal Farma (NTF) di Jepara Desa Margo Sakti, Kecamatan Labuhan Ratu, Kabupaten Lampung Timur dari Februari sampai April 2015.  Tanaman yang dibudidayakan di PT NTF yaitu pisang Cavendish, nenas, jambu biji kristal, dan buah naga.  Sistem irigasi yang digunakan untuk mengairi pisang Cavendish adalah irigasi tetes tipe emiter Aries.  Metode penyiraman yang digunakan dengan menggunakan sistem irigasi tetes pada tanaman pisang Cavendish yaitu metode penyiraman silang dan blok.Tujuan dari penelitian yaitu menentukan kinerja sistem irigasi tetes pada tanaman pisang Cavendish dengan menggunakan dua metode penyiraman.  Indikator kinerja sistem irigasi meliputi efisiensi penyaluran, koefisien keseragaman air, lama waktu irigasi, dan jumlah pemakaian bahan bakar mesin pompa.Hasil penelitian menunjukkan bahwa efisiensi penyaluran irigasi tetes dengan metode penyiraman silang sebesar 90,2% dan 80,0% dengan metode penyiraman blok.  Koefisien keseragaman air irigasi dengan metode penyirman silang sebesar 87,55% tergolong baik dan 97,10% tergolong sangat baik dengan metode penyiraman blok.  Jumlah pemakaian BBM solar untuk luas 10,46 ha dengan metode penyiraman silang sebesar 29,49 l dan 40,52 l dengan metode peyiraman blok.

Abstract

This study aims to determine the best clone species and the best dosage of Salvinia natans compost on the growth and physiological character of lowland tea. This study aims to determine the best types of clones and dosage of Salvinia natans compost for growth and physiological character of lowland tea. This study used a randomized block design experiment with three replications arranged in factorial 2x4. The first factor is a type of clones consists of two (2) levels, namely: Gambung 6 (G1) and Gambung 7 (G2). The second factor is the dosage of Salvinia natans compost with topsoil 100% (K0), topsoil and Salvinia natans compost comparison by1: 1(K1), topsoil and Salvinia natans compost comparison by2: 1(K2), dan topsoil and Salvinia natans compost comparison by3: 1(K3). All data were analyzed for the variance. Analysis followed by separation of means using LSD test with significance level of 5%. The results showed that the clones of Gambung 7 showed the higher value for observation variability in higher growth of seedlings (40,75) and better dry weight(10,78 g). Topsoil planting medium comparison by Salvinia natans compost (1: 1) showed the higher value for observation variability in higher growth of seedlings (42,25) and better dry weight (10,95 g). So, the conclusion is Gambung 7 for the best clone species on the growth and physiological character of lowland tea. The best dosage of Salvinia natans compost on the growth and physiological character of lowland tea is topsoil planting medium comparison by Salvinia natans compost (1: 1).

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.
