EFEK PEMBERIAN PUPUK HAYATI KONSORSIUM TERHADAP PERTUMBUHAN DAN HASIL TANAMAN SAWI (Brassica juncea L.)
Full text linkFertilizer is one of the important limited factor in plant cultivation system. Biofertilizer is a kind of fertilizer which improve nutrient availability in soil and subsequently plant yield. A research was carried out in village Waiheru, District Baguala, Ambon to determine the effect of different level of mixed biofertilizer on the growth and yield of caisim that grown on Alluvial. The research used Randomized Completely Block Design (RCBD) with three concentration of liquid biofertilizer, namely: 0.1%, 0.5% and 1%. Treatment control was without biofertilizer. The results showed that inoculation of liquid biological fertilizer at concentration of 1% improved growth and yield of caisim higher than the concentration of 0.1% and 0.5%. Inoculation of 1% biofertilizer increased the fresh weight of caisim shoot up to 37.36% compared to that of controls. While, fresh weight of caisim with biofertilizer of 0.1% and 0.5% was 24.52% and 28.94% respectively.Keyword: Ambon, Mixed Biofertilizer, Caisi
PERBANYAKAN Trichoderma harzianum PADA MEDIA BERBASIS ELA SAGU
Full text linkTrichoderma harzianum has been widely known as biological control agents of plant diseases. To obtain inoculum in large quantities waste agricultural products could be used as media. Ela sago is solid wastes originated from sago processing, contains C-organic, nitrogen, phosphorus, potassium, calcium, magnesium, as well as crude protein, fat, crude fiber, ash, cellulose, hemicellulose, lignin, and silica. The objective of this laboatory experiment was to determina the capacity of ela sagu in combination with rice bran and husks as T. harzianum inoculum production. The research was conducted in laboratorium Nemathology, Plant Pathology Agriculture Faculty of Pattimura University. The experiment was conducted from March to April 2014. The medium testedin this experiment were ela sago, ela sago + husk, ela sago + bran, ela sago + husk + bran, husk, bran, husk + bran, and corn. The experiment was set up by using a completely randomized design, replicated three times. The experimental results showed that the number of conidiumon mixed media ela sago + bran and ela sago + bran + husk reached up to 1011 per g media and significantly greater than that of ela sago, elasago + husk, Husk + bran, husk, bran, and corn media
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
Optimasi Media Ela Sagu Dan Dedak Untuk Pertumbuhan Dan Produksi Jamur Volvariella sp.
Full text linkJamur Volvariella sp. berpotensi sebagai salah satu sumber pangan yang belum dibudidayakan oleh masyarakat. Jamur ini memiliki habitat khusus yaitu pada limbah olehan pati sagu yang dikenal dengan sebutan ela sagu. Tujuan penelitian ini untuk mendapatkan konsentrasi dedak yang dapat ditambahkan pada ela sagu dan pada luasan permukaan media yang baik untuk pertumbuhan dan produksi jamur Volvariella sp. Penelitian merupakan percobaan dua faktor yaitu konsentrasi dedak dalam ela sagu yaitu 0%, 10%, 20%, dan 30%, dan luasan permukaan media tumbuh yakni 875 cm2 , 625 cm2, dan 375 cm2. Penelitian dirancang menggunakan Rancangan Acak Lengkap (RAL) dengan tiga ulangan. Hasil penelitian ditemukan bahwa penggunaan ela sagu yang ditambahkan dengan dedak dan ditempatkan pada wadah dengan ukuran luas permukaan berbeda berpengaruh terhadap jumlah tubuh buah tumbuh, jumlah tubuh buah panen, dan bobot segar tubuh buah konsumsi, dan tidak berpengaruh terhadap diameter tubuh buah konsumsi, tinggi tubuh buah konsumsi, bobot rata-rata tubuh buah konsumsi. Ela sagu dengaan persentase dedak 10 % dan ditempatkan pada wadah dengan luas permukaan 875 cm2 lebih baik untuk meningkatkan jumlah tubuh buah tumbuh dan tubuh buah panen jamur Volvariella sp
