No full textPenggunaan pupuk yang tepat gunan dan efisien memerlukan teknik sederhana yaitu metode tempel misel organik-anorganik dengan proses inkubasi. Metode ini sudah terbukti pada praktek penanaman padi metode SRI (the Sistem of Rice Intensification) pada sawah bukaan baru. Pembuktian untuk tanaman kacang hijau sangat diperlukan sebagai karakter tanaman berumur pendek pada jenis leguminosa. Fungsi tanaman kacang hijau tidak dapat diragukan apalagi pada kondisi pandemic Covid-19 saat ini, karena ada kandungan asam amino Lysine yang mampu meningkatkan daya tahan tubuh dari serangan virus. Metode tempel misel organik-anorganik berasal dari hasil kompos dalam hal ini kompos asal feses sapi melalui inkubasi 21 hari. Pembuatan 1 t.ha-1 pupuk diperlukan 80% kompos, 20% tanah lempung berliat, dan berturut-turut Urea, SP-36 dan KCl sebanyak 15, 12.5, dan 7.5 kg. Perlakuan dosis pupuk di zona akar berturut-turut 0, 1, 2, 3 dan 4 t.ha-1 dengan pengulangan sebanyak 4 kali dalam media tanam polibag 6 kg tanah Ultisol. Pengujian dapat memberikan informasi bahwa (1) berbagai dosis pupuk metode tempel organik-anorganik mampu meningkatkan pertumbuhan dan komponen hasil tanaman kacang hijau, (2) penggunaan dosis pupuk 2 t.ha-1 menunjukkan hasil terbaik terhadap pertumbuhan tanaman, komponen hasil dan hasil biji kacang hjau, dan (3) penggunaan dosis pupuk metode tempel organik-anorganik berlebihan sebesar 3-4 t.ha-1 cenderung melambatkan waktu berbunga termasuk penundaan waktu panen, meningkatkan tinggi tanaman dan bahkan menurunkan hasil biji. Karena pengujian ini pada skala pot terbatas, maka disarankan untuk penerapannya di lapangan pada luasan tertentu (125 m2

The Effect of Bioorganic Dosage with N, P Fertilizer on Rice Production of Sri Methods and Increased Nutrient Content of Paddy Soil Intensification
Get PDFThe System of Rice Intensification (SRI) operates under aerobic conditions so that helpful microbes are active and abundant. Effective N-fixing rhizobacteria and indigenous phosphate solubilizers Azotobacter and Pseudomonas grow well in the organic compost Bioorganic because it resembles their natural habitat. The purpose of this research is to find out the right dose of Bioorganic fertilizer and the most N and P doses needed to optimize the SRI method of rice crop production. This research uses a factorial randomized block design. The first factor is Bioorganic fertilizer dosage (1, 3, and 6) t ha-1. The second factor is the dose of N and P fertilizers to use (0, 25, 50, and 75)% of the recommended dosage. The results of this study inform you about Bioorganic fertilizers containing Azotobacter and Pseudomonas fluorescens indigenous. Azotobacter bacteria produce the availability of nutrients N, which functions as Plant Growth Promoting Rhizobacteria (PGPR), these bacteria quickly colonize the root system, regulate hormonal balance, nutrition, and encourage resistance to pathogens. Pseudomonas fluorescens bacteria acts as a provider of phosphorus and nutrients in the generative phase. Both of these microbes have a role in SRI method of rice plant metabolism to increase vegetative and generative growth of rice plants with SRI method with production reaching production of 8.80 t ha-1 in B2 (3 t ha-1) and N2P2 (50%) with the production of 9.21 t ha-1, so the use of inorganic fertilizers is more efficient. Rice soil nutrient status increased pH from slightly acidic to neutral, C-organic increased from 1.27% (low) to 9.30-10.68% (high), N total from 0.13% (low) to 0.45-0.58% (high), P- available from 13.0 ppm reaching 18.0-20.0 ppm (moderate), the Bioorganic application has not been able to increase the C: N, CEC value and base saturation. Nutrient uptake of N and P on the leaves of rice plants is better at dose B2. Bioorganic applications increase the nutrient content of paddy soils planted with the SRI method compared to initial soil nutrient analysis
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
PENGARUH DOSIS DAN UMUR SIMPAN PUPUK ORGANO-KOMPLEKS TERHADAP PERTUMBUHAN DAN PRODUKSI PADI METODE SRI (The System of Rice Intensification)
No full textSawah yang baru dibuka memiliki sifat fisik yang buruk dan status hara rendah, disamping gangguan Fe2+ terlarut yang tinggi pada zona perakaran apabila tergenang, sehingga dalam kurun waktu 5-10 tahun belum dapat normal dan hasil selalu rendah yaitu 1,0-2,5 t/ha dan menyebabkan kebutuhan pupuk lebih besar. Pupuk Organo-Kompleks (OK) dapat menjawab kondisi tersebut dan tidak memerlukan waktu 5-10 tahun. Karakteristik pupuk OK diuji dalam dosis dan umur simpan terhadap pertumbuhan dan produksi padi metode SRI. Penelitian dilaksanakan bulan Juni 2019 sampai bulan November 2019 di rumah plastik. Pengujian secara faktorial, faktor pertama dosis OK (A1 = 10 t/ha dan A2 = 20 t/ha) dan faktor kedua umur simpan OK, B1= maksimum 1 bulan; B2= 6 bulan dan B3= 12 bulan dengan kombinasi A1B1; A1B2; A1B3; A2B1; A2B2; dan A2B3 (4 ulangan), data pengamatan dianalisis dengan pengolah data Statistic-8 dan dengan uji lanjut BNT 5%. Peningkatan dosis OK 2x lipat (20 t/ha) dapat meningkatkan pertumbuhan (tinggi tanaman dan bobot jerami), komponen hasil (jumlah malai/rumpun, jumlah biji/malai, bobot 1000 biji, dan persentase gabah bernas) dan hasil gabah. Penyimpanan pupuk OK mampu bertahan hingga 6 bulan dan seterusnya berdampak terhadap penurunan potensinya pada tanaman. Peningkatan dosis OK tidak menaikkan hasil pada lama simpan di atas 6 bulan
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
