Penentuan Ukuran Pesanan Bahan Baku Pipa HDPE yang Optimal dengan Simulasi di PT. Polyvindo Abadi Sukses
No full textPT. Polyvindo Abadi Sukses is an industrial company engaged in the production of pipes. In producing HDPE pipes, the company uses various raw materials ordered from foreign suppliers. The raw material needed in the HDPE pipe production process is HDPE plastic seeds. The company orders raw materials to meet existing demand, inventory stocks often experience differences with demand and orders are made if there is not enough supply to meet demand, Shipments of materials in containers via sea transport with a square off time of 1 month. In practice the number of orders is determined based on the number of requests in 1 month. As a result, inventory can be excessive or vice versa is not enough to fulfill orders. From the description above, the problems faced by PT. Polyvindo Abadi Sukses is that there is no policy in determining the amount of ordering raw materials that cause shortages or excess raw materials in a certain period. Therefore the determination of the optimal number of orders needs to be done using simulations of HDPE pipe raw materials. The purpose of this study is to design a simulation model of optimal HDPE raw material ordering with a minimum total cost of inventory, Analyzing HDPE pipe demand distribution patterns, Analyzing total inventory costs by simulating at various levels of order size. In this study the method used is a simulation to determine the optimal HDPE raw material order quantity with total inventory cost (Total Cost Inventory) as a comparison, the order size determination is also carried out using the probabilistic EOQ method. The results of these two methods are then compared to choose the best way and to determine the optimal order size. With the EOQ method, the economic order size is 147.805 kg, with a total inventory cost of Rp.732,662,683. While the results of the Q system simulation, conducted with experiments at the level of uk 50,000, 60,000, 70,000, and 80,000 kg. The optimal order size for a reorder point of 60,000 kg is 80,000 kg and a total inventory cost of 378,465,389, -. Thus the optimal order size with the Q system is 80,000kg at a reorder point of 60,000kg.PT. Polyvindo Abadi Sukses merupakan perusahaan industri yang bergerak dalam produksi pipa. Dalam memproduksi pipa HDPE, perusahaan menggunakan berbagai bahan baku yang dipesan dari pemasok luar negeri. Bahan baku yang diperlukan dalam proses produksi pipa HDPE adalah biji plastik HDPE. perusahaan melakukan pemesanan bahan baku untuk memenuhi permintaan yang ada, stok persediaan sering mengalami selisih dengan permintaan dan pemesanan dilakukan jika persediaan tidak cukup untuk memenuhi permintaan, Pegiriman bahan dalam kontainer melalui angkutan laut dengan waktu ancang – ancang 1 bulan. Dalam prakteknya jumlah pesanan ditentukan berdasarkan jumlah permintaan dalam 1 bulan. Akibatnya persediaan dapat berlebih ataupun sebaliknya tidak cukup untuk memenuhi order. Dari uraian latar belakang diatas, permasalahan yang dihadapi PT. Polyvindo Abadi Sukses adalah tidak ada kebijakan dalam menetukan jumlah pemesanan bahan baku yang menyebabkan kekurangan atau kelebihan bahan baku pada periode tertentu. Oleh sebab itu penentuan jumlah pesanan yang optimal perlu dilakukan dengan menggunakan simulasi terhadap bahan baku pipa HDPE. Tujuan penelitian ini adalah merancang model simulasi jumlah pemesanan bahan baku HDPE yang optimal dengan total biaya persediaan (Total Cost Inventory) Minimum, Menganalisis pola distribusi permintaan pipa HDPE, Menganalisis total biaya persediaan dengan simulasi pada berbagai level ukuran pesanan. Pada penelitian ini metode yang digunakan adalah simulasi untuk menentukan jumlah pesanan bahan baku HDPE yang optimal dengan total biaya persediaan (Total Cost Inventory) sebagai pembanding, penentuan ukuran pesanan juga dilakukan dengan menggunakan metode EOQ probabilistik. Hasil dari kedua cara ini kemudian dibandingkan untuk memilih cara yang terbaik dan untuk menentukan ukuran pesanan yang optimal. Dengan metode EOQ ukuran pemesanan ekonomis adalah 147,805 Kg, dengan total biaya persediaan sebesar Rp.732.662.683,-. Sedangkan dari hasil Simulasi sistem Q, yang dilakukan dengan eksperimen pada level ukurna 50.000, 60.000, 70.000, dan 80.000Kg. Ukuran pesanan yang optimal untuk reorder point 60.000Kg adalah 80.000Kg dan total biaya persediaan sebesar 378.465.389,-. Dengan demikian ukuran pesanan yang optimal dengan sistem Q adalah 80.000kg pada reorder point 60.000kg.120 HalamanSkripsi Sarjan
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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 textIn 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.
