    Tanaman padi (Oryza sativa L) merupakan salah satu komoditas tanaman pangan yang harus ditingkatkan produktivitasnya untuk memenuhi kebutuhan beras di dalam negeri. Salah satu upaya yang dapat dilakukan untuk meningkatkan produktivitas padi adalah dengan menerapkan budidaya padi metode SRI (The System of Rice Intensification) dengan pemberian frekuensi dan konsentrasi pupuk hayati. Penelitian ini bertujuan untuk memperoleh frekuensi dan konsentrasi pupuk hayati yang tepat terhadap pertumbuhan dan hasil tanaman padi metode SRI. Penelitian ini dimulai Oktober 2023 sampai Februari 2024. Percobaan dilakukan dengan menggunakan rancangan acak kelompok (RAK) faktorial dengan 2 faktor. Faktor pertama yaitu frekuensi pemberian pupuk hayati (2 kali, 3 kali, dan 4 kali pemberian). Faktor kedua yaitu konsentrasi pupuk hayati (0 ml/L, 5 ml/L, 10 ml/L, dam 15 ml/L). Data pengamatan dianalisis dengan sidik ragam dan F hitung perlakuan yang berbeda nyata dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf 5%. Hasil analisis menyatakan bahwa pemberian pupuk hayati pada konsentrasi 10 ml/L dan 15 ml/L dengan 2 kali pemberian sama-sama dapat meningkatkan hasil tanaman padi metode SRI. Peningkatan hasil ini terjadi sejalan dengan peningkatan komponen hasil : jumlah anakan produktif dan bobot gabah kering per rumpun. Selain itu, produksi yang tinggi tersebut juga karena pertumbuhan vegetatif yang lebih baik pada pemberian 10 ml/L dan 15 ml/L jika dibandingan dengan tanpa pemberian 0 ml/L dan 5 ml/L pemberian pupuk hayati

    Rice (Oryza sativa L.) is a food crop commodity that plays an important role in Indonesia. One of the efforts made to increase rice productivity is by applying the SRI (The System of Rice Intensification) method. Obstacles found in the application of SRI method of rice cultivation in the field are weeds that are difficult to overcome. Weed problems in SRI rice cultivation can be overcome by using organic mulch. This study aims to determine the best type of organic mulch for the growth and yield of rice plants using the SRI method in suppressing weed growth. The research was arranged using a randomized block design (RBD) which consisted of 3 mulch treatments at a dose of 10 tons/ha, namely rice straw mulch (A1); corn leaf mulch (A2); paitan mulch (A3). The results showed that the application of organic mulch had no significant effect on the growth and yield components of rice plants. The results also showed that the application of organic mulch had a significant effect on the fresh weight of weeds that were weeded at 3, 5, 7 WAP. The weeds that most dominated the plots were weeds with a puzzle type, namely the Cyperus esculentus species. Key-words: Rice, SRI Method, MulchINTISARITanaman padi (Oryza sativa L.) merupakan komoditas tanaman pangan yang memegang peranan penting di Indonesia. Salah satu upaya yang dilakukan untuk meningkatkan produktivitas padi adalah dengan penerapan metode SRI (The System of Rice Intensification). Kendala yang didapati dalam penerapan budidaya padi metode SRI di lapangan adalah gulma yang sulit diatasi. Permasalahan gulma pada budidaya padi SRI dapat diatasi dengan cara pemakaian mulsa organik. Penelitian ini bertujuan untuk mengetahui jenis mulsa organik yang terbaik terhadap pertumbuhan dan hasil tanaman padi metode SRI dalam menekan pertumbuhan gulma. Penelitian disusun menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari 3 perlakuan mulsa dengan dosis 10 ton/ha yaitu, mulsa  jerami padi (A1); mulsa daun jagung (A2); mulsa paitan (A3). Hasil penelitian menunjukkan bahwa pemberian mulsa organik tidak berpengaruh nyata terhadap komponen pertumbuhan dan hasil tanaman padi. Hasil penelitian juga menunjukkan bahwa pemberian mulsa organik berpengaruh nyata terhadap bobot segar gulma yang disiangi pada 3, 5, 7 MST. Gulma yang paling mendominasi petakan adalah gulma dengan jenis teki-tekian yaitu gulma spesies Cyperus esculentus. Kata kunci: Padi, Metode SRI, Muls

    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
