UPAYA EFISIENSI DAN PENINGKATAN KETERSEDIAAN NITROGEN DALAM TANAH SERTA SERAPAN NITROGEN PADA TANAMAN PADI SAWAH ( Oryza sativa L.)
Full text linkNutrients or nutrients are important factors for plant growth which can be likened to food substances for plants. One of the factors that support plants to grow and produce optimally is the availability of nutrients in sufficient quantities in the soil. The elements N, P and K, have a very important role in plant growth and production. The purpose of the preparation of the paper is to provide information about efforts to improve efficiency and availability of nitrogen in the soil and nitrogen uptake in lowland rice plants (Oryza sativa L.) Nitrogen has a role as a constituent of enzymes which plays a large role in plant metabolism but is relatively not available to plants. The efficiency of the use of Nitrogen (N) fertilizer in lowland rice can be maximized by way of 1) timely fertilization, 2) planting superior varieties that are responsive to the administration of Nitrogen (N), 3) improving cultivation techniques, 4) regulating the timing of Nitrogen fertilizer (N ) the right during the growing season with Leaf Color Chart (LCC) or Leaf Color Chart (BWD) and 5) NPK fertilization simultaneously. Efforts to increase the availability of nitrogen in the soil and uptake in wetland rice can be done by adding high-quality organic matter, the use of Azotobacter isolates as biological fertilizers to reduce the decrease in soil health due to the input of synthetic chemicals
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
UPAYA PENINGKATAN PRODUKTIVITAS TANAMAN KACANG TANAH DAN PERBAIKAN KESUBURAN TANAH PODZOLIK MERAH KUNING MELALUI PEMANFAATAN TEKNOLOGI BIOCHAR DI SULAWESI TENGGARA
Full text linkDi Indonesia, saat ini Kacang Tanah (Arachis hypogaea L.) sudah menjadi komoditas penting dan strategis.Kondisi lahan pertanian di Sulawesi Tenggara sebagian besar didominasi oleh tanah Podzolik Merah Kuning. Menurunnya kesuburan tanah merupakan salah satu penyebab rendahnya produktivitas kacang tanah. Tujuan penyusunan makalah yaitu untuk memberikan informasi tentang upaya peningkatan produktivitas tanaman kacang tanah dan perbaikan kesuburan tanah podzolik merah kuning melalui pemanfaatan teknologi biochar di Sulawesi Tenggara.
Pemanfaatan limbah pertanian serta kotoran hewan memiliki potensi besar sebagai biochar atau arang hayati tahan pelapukan di Sulawesi Tenggara. Teknologi biochar memiliki potensi meningkatkan kandungan ketersediaan carbon dalam mampu, memperbaiki kemampuan tanah dalam menahan air dan mengurangi kehilangan unsur hara. Aplikasi teknologi biochar dapat memberikan efek baik melalui perbaikan sifat fisik tanah, biologi tanah dan kimia tanah dengan memasok sejumlah nutrisi yang penting bagi pertumbuhan dan peningkatan hasil panen tanaman kacang tanah
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
Peningkatan Pertumbuhan dan Hasil Tanaman Kedelai (Glycine max L. Mer.) Setelah Implementasi Jenis Bahan Organik dan Pemulsaan Pada Tanah Podsolik Merah Kuning di Sulawesi Tenggara
Full text linkDi Indonesia, tanaman kedelai sebagai komoditas strategis ketiga setelah padi dan jagung. Produk kedelai menjadi sumber protein bagi manusia. Permintaan kedelai mengalami peningkatan, namun produksi masih rendah. Salah satu penyebab rendahnya produksi kedelai di Sulawesi Tenggara ialah memburuknya kesuburan fisik, kimia dan biologi tanah. Tujuan penelitian ialah untuk mempelajari peningkatan pertumbuhan dan hasil tanaman kedelai setelah implementasi jenis bahan organik dan pemulsaan pada tanah podsolik merah kuning di Sulawesi Tenggara. Penelitian dilaksanakan dengan menggunakan Rancangan Acak Kelompok dalam pola Faktorial (RAK-Faktorial). Hasil penelitian menunjukkan Implementasi jenis bahan organik pupuk kandang sapi, ampas sagu dan pemulsaan alang-alang dapat meningkatkan pertumbuhan dan hasil tanaman kedelai. Terdapat perbedaan pertumbuhan dan hasil tanaman kedelai setelah implementasi jenis bahan organik pupuk kandang sapi, ampas sagu dan mulsa alang-alang pada tanah podsolik merah kuning. Interaksi antara jenis bahan organik pupuk kandang sapi dan ampas sagu serta pemulsaan alang – alang berperan dalam mendukung peningkatan jumlah polong isi perTanaman kedelai.
