    Di era modern revolusi industri 4.0 saat ini, hampir semua teknologi informasi digunakan untuk memudahkan aktivitas manusia. Salah satu contohnya adalah dalam sektor pertanian. Teknologi rumah kaca merupakan teknologi yang dapat menjadi solusi permasalahan perkebunan. Permasalahan perkebunan saat ini adalah semakin menyempitnya komoditas tanaman yang dapat ditanam akibat cuaca ekstrim dan permasalahan semakin sempitnya lahan akibat pembangunan perumahan dan industri. Padahal jumlah penduduk semakin meningkat dan kebutuhan akan pangan juga semakin meningkat. Untuk mengatasi masalah ini, banyak perangkat dan metode telah dikembangkan untuk pemantauan rumah kaca, dengan tujuan meningkatkan produktivitas tanaman. Sebelumnya telah dikembangkan berbagai sistem rumah kaca, namun pengembangannya masih terbatas pada satu sensor atau satu node dan protokol pengiriman data yang digunakan mayoritas menggunakan protokol HTTP. Oleh karena itu, pada tugas akhir ini dikembangkan sistem monitoring kondisi rumah kaca dengan menyusun beberapa sensor yang kemudian disebut node sensor dan menempatkan node sensor pada titik tertentu. Node sensor kemudian akan mengirimkan datanya ke sink node menggunakan Bluetooth Low Energy dengan tujuan untuk mengabungkan data yang dibaca oleh masing-masing node sensor. Kemudian data yang telah digabungkan pada sink node tersebut diteruskan oleh sensor node 3 ke broker MQTT menggunakan konektivitas WiFi. Data tersebut kemudian akan disubscribe menggunakan JavaScript untuk diolah dan disimpan dalam database. Lalu aplikasi website akan menampilkan data pembacaan sensor sesuai dengan yang tersimpan di database. Dalam aplikasi website terdapat fitur untuk menyesuaikan parameter lingkungan rumah kaca, fitur tersebut disebut set threshold. Data dari threshold yang telah diatur selanjutnya dikirimkan ke node aktuaktor. Node aktuaktor bertugas untuk membandingkan data dari pembacaan sensor dan juga data threshold agar dapat menjalankan beberapa aktuaktor sesuai dengan kebutuhannya. ======================================================================================================================================= In the modern era of Industry 4.0 revolution today, almost all information technology is used to facilitate human activities. One example is in the agricultural sector. Greenhouse technology is a technology that can be a solution to farming problems. The current farming problem is the narrowing of the commodities that can be planted due to extreme weather and the narrowing of land due to housing and industrial development. Yet, the population is increasing and the need for food is also increasing. To overcome this problem, many devices and methods have been developed for greenhouse monitoring, with the goal of increasing plant productivity. Various greenhouse systems have been developed before, but their development is still limited to one sensor or one node and the data transmission protocol used is mostly using the HTTP protocol. Therefore, in this final project a greenhouse condition monitoring system is developed by assembling several sensors which are then called sensor nodes and placing sensor nodes at certain points. The sensor nodes will then send their data to the sink node using Bluetooth Low Energy with the aim of combining the data read by each sensor node. Then the data that has been combined at the sink node is forwarded by sensor node 3 to the MQTT broker using WiFi connectivity. The data will then be subscribed using JavaScript to be processed and stored in database. Then the website application will display the sensor readings according to what is stored in the database. In the website application, there is a feature to adjust the greenhouse environment parameters, this feature is called set threshold. Data from the set threshold is then sent to the actuator node. The actuator node is responsible for comparing data from sensor readings and also threshold data in order to run some actuators as needed

    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.
