EFISIENSI PENGGUNAAN AIR DENGAN IRIGASI TETES UNTUK PERTUMBUHAN TANAMAN SELADA
Full text linkIrigasi Tetes Sederhana adalah penyiraman tanaman otomatis dan murah. Irigasi Tetes Sederhana merupakan teknik penyiraman tanaman yang menggunakan sebuah tandon air atau tempat penampungan air bisa berupa botol bekas yang diberi saluran untuk menetesi media tanam sedikit demi sedikit secara konstan, sehingga media tanam tetap tercukupi kebutuhan airnya, tanpa menjadi tergenang dan ketersediaan air tercukupi. Penelitian bertujuan untuk mengetahui efisiensi air dengan irigasi tetes terhadap pertumbuhan tanaman selada. Metode yang digunakan adalah metode eksperimen dengan menggunakan Rancangan Acak Kelompok (RAK) terdiri dari 3 perlakuan yaitu 3 kali ulangan sehingga diperoleh 12 unit percobaan pertama P1= pemberian air 300ml, kedua P2= pemberian air 200ml, dan P3= pemberian air 100ml dan dianalisis menggunakan analisis keragaman (Anova) pada taraf nyata 5% dan apabila terdapat perlakuan yang berpengaruh secara nyata maka dilakukan uji dengan menggunakan uji beda nyata jujur (BNJ) pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa Pemberian irigasi tetes tidak berpengaruh nyata pada parameter ketinggian tanaman, berat berangkas kering, diameter batang, tekstur tanah tetapi berbeda nyata pada berat berangkas basah dan untuk Perlakuan terbaik diperoleh pada perlakuan P2 dimana menghasilkan berat berangkasan basah tertinggi sebesar 93 gr
TEKNIK PENGELOLAAN GREENHOUSE DI KELURAHAN JEMPONG BARU
Full text linkKelurahan Jempong Baru Kecamatan Sekarbela merupakan memiliki luas lahan sebesar 580 Ha. Dari luas tersebut 67,83% (393,46 Ha) merupakan lahan pertanian produktif. Namun pemanfaatannya belum optimal. Dari total penduduk sebesar 17.034 orang di Jempong Baru 25,34 % (4.318 Orang) tidak memiliki pekerjaan. Tingginya jumlah penduduk bekerja di sektor non pertanian mempengaruhi kesempatan untuk mengerjakan lahan pertanian yang dimiliki. Sehingga banyak lahan pertanian yang tidak tergarap maksimal. Pembangunan greenhouse sederhana dilahan pekarangan memungkinkan dilakukan, mengingat tidak membutuhkan biaya banyak dan waktu yang singkat. Tetapi tidak semua penduduk mengetahui cara pengelolaan greenhouse yang baik. Pengabdian pada masyarakat yang dilakukan di Kelurahan Jempong Baru melatih dan mendampingi cara mengelola greenhouse secara efektif dan efisien. Usaha intensifikasi greenhouse dapat dilakukan dengan memanfaatkan setiap jengkal ruangan yang tersedia untuk kegiatan produktif dengan produk untuk membantu memenuhi gizi dan menjaga kesehatan. Adapun usaha yang dilakukan dengan cara bercocok tanam sayuran dan menanam tanaman obat keluarga (TOGA). Abstract: Jempong Baru Village, Sekarbela District is a land area of 580 ha. Of this area 67.83% (393.46 ha) is productive agricultural land. But the utilization is not optimal. Of the total population of 17,034 people in Jempong Baru, 25.34% (4,318 people) do not have jobs The high number of residents working in the non-agricultural sector influences the opportunity to work on agricultural land owned. So that a lot of agricultural land is not maximized. The construction of a simple greenhouse in the yard area is possible, considering that it does not require a lot of money and a short time. But not all residents know how to manage a good greenhouse. Community service done in Jempong Baru Village trains and accompanies how to manage greenhouses effectively and efficiently. Efforts to intensify greenhouses can be done by utilizing every inch of space available for productive activities with products to help meet nutrition and maintain health. The business is done by planting vegetables and Growing Family Medicinal Plants (GFMP)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
