PENGARUH PEMBERIAN ECO ENZYME TERHADAP INTENSITAS SERANGAN HAMA TANAMAN PAKCOY (Brasica rappa L)
No full textSayuran hijau pada umumnya kaya akan sumber gizi yang penting bagi manusia. Salah satunya adalah sayuran pakcoy (Brassica rappa L). Permintaan pakcoy semakin meningkat seiring dengan bertambahnya penduduk di Indonesia. Permintaan yang tinggi harus diimbangi dengan produksi lokal yang tinggi pula. Tujuan dari penelitian ini yaitu mengetahui pengaruh pemberian eco enzyme terhadap intensitas hama tanaman pakcoy. Metode yang dilakukan untuk penelitian ini menggunakan metode eksperimen dengan rancangan Acak Kelompok (RAK) Faktorial 3x3 dengan 3 perlakuan dan 3 pengulangan. Hasil penelitian yang diperoleh adalah Penyemprotan eco enzym dengan konsentrasi 2 ml/L dapat menolak kehadiran hama pada tanaman pakcoy.

Pengaruh Frekuensi Pemberian Pupuk Organik Cair dan Takaran Biochar terhadap Pertumbuhan dan Hasil Sawi Pakcoy (Brassica rappa L.)
Get PDFThis study aims to determine the effect of the frequency of application of liquid fertilizer and biochar on the growth and yield of pakcoy plants and to obtain the frequency of application of liquid fertilizer that is appropriate for the growth and yield of pakcoy plants. This research has been carried out for one planting season from August to September 2020, on Mr Marten Kaet's land, located in Benpasi Village, Kefamenanu City District, North Central Timor Regency (TTU), East Nusa Tenggara Province (NTT). Using a 2 Factorial Randomized Block Design (RBD), namely: The first factor: Biochar which consists of 3 levels, namely: Biochar 10 t / ha, Biochar 20 t / ha, Biochar 30 t /Ha. The second factor is the frequency of watering liquid fertilizer which consists of 4 levels of treatment, namely: 5ml / liter of water: 2 times a week, 5ml / liter of water: 1 time a week, 10 ml / liter of water : 2 times a week, 10 ml / liter of water: once a week. So there are 12 treatment combinations, namely: B1F1, B1F2, B1F3, B1F4, B2F1, B2F2, B2F3, B2F4, B3F1, B3F2, B3F3, B3F4which were repeated as many 3 times so that there are 36 experimental units. The results showed no interaction and significant differences between the treatment of biochar dose and POC watering frequency on the growth and yield of mustard greens (Brassica rappa L.). But there was a significant difference in the leaf area parameters. The results showed that the treatment of 30 t/ha biochar dose and 5 ml / L POC watering frequency was able to increase the growth and yield of mustard greens (Brassica rappa L.). This was indicated by the highest value given both on environmental parameters, growth and the result.Penelitian ini bertujuan untuk mengetahui pengaruh frekuensi pemberian pupuk organik cair dan biochar terhadap pertumbuhan dan hasil tanaman pakcoy dan untuk mendapatkan frekuensi pemberian pupuk cair yang tepat untuk pertumbuhan dan hasil tanaman pakcoy. Penelitian ini telahdilaksanakan selama satu kali musim tanam dari bulan Agustus sampai September 2020, di Lahan Bapak Marten Kaet yang berlokasi di Kelurahan Benpasi, Kecamatan Kota Kefamenanu, Kabupaten Timor Tengah Utara (TTU), Provinsi Nusa Tenggara Timur (NTT). Menggunakan Rancangan Acak Kelompok (RAK) 2 Faktorial yaitu: Faktor pertama: biochar yang terdiri dari 3 taraf, yaitu: biochar 10 t/ha, biochar 20 t/ha, biochar 30 t/ha. Faktor kedua adalah frekuensi penyiraman pupuk cair yang terdiri dari 4 taraf perlakuan, yaitu: 5ml/liter air: 2 kali seminggu, 5ml/liter air: 1 kali seminggu, 10 ml/liter air: 2 kali seminggu, 10 ml/liter air: 1 kali seminggu.Sehingga terdapat 12 kombinasi perlakuan, yaitu: B1F1, B1F2, B1F3, B1F4, B2F1, B2F2, B2F3, B2F4, B3F1, B3F2, B3F3, B3F4yang diulang sebanyak 3 kali sehingga terdapat 36 satuan unit percobaan. Hasil penelitian menunjukkan bahwa tidak terjadi interaksi serta beda nyata antara perlakuan takaran biochar dan frekuensi penyiraman POC terhadap pertumbuhan dan hasil tanaman sawi (Brassica rappa L.). Namun terjadi beda nyata pada parameter luas daun. Pada perlakuan takaran biochar 30 t/ha dan frekuensi penyiraman POC 5 ml/L mampu meningkatkan pertumbuhan serta hasil tanaman sawi (Brassica rappa L.)
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
