    ABSTRAK FIKA SUNARTONO, Faktor-Faktor Fisik Yang Mempengaruhi Produktivitas Padi Sawah Di Kecamatan Kertajati Kabupaten Majalengka. Skripsi. Jakarta: Program Studi Pendidikan Geografi Fakultas Ilmu Sosial. Universitas Negeri Jakarta. 2021. Tujuan dalam penelitian ini yaitu mengetahui faktor dominan yang mempengaruhi produktivitas tanaman padi sawah. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif menggunakan data sekunder. Berdasarkan data sekunder yang diperoleh dari Balai Besar Sumber Daya Lahan Pertanian (BBSDLP) diketahui bahwa kondisi fisik tanah di lokasi penelitian yaitu kedalaman tanah dalam >50 cm, drainase terhambat dan tekstur tanah halus. Faktor kimia tanah (pH tanah) 4,5 – 6,5. Kemiringan lereng yang mendominasi yaitu kemiringan lereng <15 % (datar) dan kondisi topografi 40 – 50 mdpl. Data faktor unsur iklim didapatkan dari Stasiun Meteorologi Jatiwangi yaitu diantaranya kondisi rata-rata curah hujan pada tahun 2016-2019 yaitu 3077-1950 mm/tahun, panjang musim hujan 180 harian per tahun, suhu udara minimum 26°C – suhu udara maksimum 37°C dengan rata-rata kelembaban 60% - 88%. Serta fator teknis dari jaringan irigasi menurut Indeks Kinerja Sistem Irigasi Cicabe dengan nilai 52% yang berarti dalam kondisi jelek. Untuk mengetahui faktor fisik dominan dalam penelitian ini dengan penguatan berdasarkan penelitian relevan. Maka faktor fisik dominan yang mempengaruhi produktivitas sawah tadah hujan adalah kesuburan tanah (fisik dan kimia tanah) dengan faktor pembatas (tekstur tanah halus dan pH tanah asam – hingga asam). Faktor dominan yang mempengaruhi produktivitas sawah irigasi yaitu dari faktor teknis dari jaringan irigasi yang mana kondisi jaringan irigasi jelek (tidak terawat dengan baik dan kurang lengkap) dan perlu perhatian dengan dilakukan pemeliharaan berkala yang bersifat perbaikan berat dan penggantian.

Jakarta: Geography Education Study Program. Faculty of Social and Science. State University of Jakarta. 2021. This research aims to identify physical and non-physical factors that affect productivity of rice. This research used descriptive method using secondary data. Based on secondary data obtained from Balai Besar Sumber Daya Lahan Pertanian (BBSDLP), it is known that the physical condition of the soil in the research location is a deep soil depth> 50 cm, obstructed drainage and fine soil texture. Soil chemical factor (soil pH) 4.5 - 6.5. The dominant slopes are <15% (flat) and the topographic conditions are 40 - 50 masl. Data on climatic factors were obtained from the Jatiwangi Meteorological Station, including the average rainfall conditions in 2016-2019, namely 3077-1950 mm / year, the length of the rainy season 180 days per year, minimum air temperature 26 ° C - maximum air temperature 37 ° C with an average humidity of 60% - 88%. As well as the technical facilitator of the irrigation network according to the Cicabe Irrigation System Performance Index with a value of 52% which means it is in bad condition. To find out the dominant physical factors in this study with reinforcement based on relevant research. So the dominant physical factors affecting the productivity of rainfed rice are soil fertility (soil physical and chemical) with limiting factors (fine soil texture and acidic - to acidic soil pH). The dominant factor affecting the productivity of irrigated rice fields is the technical factor of the irrigation network in which the condition of the irrigation network is poor (not well maintained and incomplete) and needs attention by carrying out periodic maintenance which is heavy repair and replacement.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
