Analisis Produktivitas dan Waste Reduction Dengan Pendekatan Metode Green Productivity.
No full textPT Ongkowidjojo merupakan sebuah perusahaan yang bergerak di bidang industri rokok. Penelitian dilakukan pada bagian produksi rokok Sigaret Kretek Mesin (SKM). Permasalahan yang terjadi pada bagian produksi rokok SKM yaitu terdapat selisih massa antara massa input yang digunakan dan output yang dihasilkan. Massa yang hilang tersebut berupa waste yang dihasilkan selama proses produksi berlangsung. Waste yang dihasilkan berupa limbah cair, limbah padat dan limbah gas yang merupakan limbah produksi dari proses primary dan secondary. Hal ini menyebabkan rendahnya tingkat produktivitas di beberapa aktivitas produksi. Sehingga dibutuhkan tindakan penanganan terhadap limbah yang dihasilkan dikarenakan akan berpengaruh pada produktivitas perusahaan. Dalam penelitian ini, metode utama yang digunakan dalam menangani permasalahan yang terjadi adalah Green Productivity (GP) yaitu metode yang bertujuan untuk meningkatkan efisiensi produksi dengan minimalisasi penggunaan sumber daya serta perbaikan kualitas lingkungan. Metode GP terdiri dari beberapa langkah yang harus dilakukan. Tahap pertama yaitu getting started, pada tahap ini dilakukan perhitungan neraca massa dan tingkat produktivitas. Pada tahap selanjutnya yaitu tahap planning dilakukan identifikasi penyebab permasalahan menggunakan diagram ishikawa dan penentuan tujuan dan target. Pada tahap generation, evaluation and prioritazion of GP options dilakukan penyusunan alternatif-alternatif solusi dalam menangani permasalahan yang disesuaikan dengan tujuan dan target yang ditetapkan. Pemilihan alternatif solusi dilakukan dengan beberapa metode yaitu berdasarkan nilai investasi, analisis kelayakan menggunakan Feasibility Analysis Matrix dan nilai Benefit Cost Ratio (BCR). Pemilihan alternatif solusi juga disesuaikan dengan tujuan dan konsep dari GP yaitu melakukan efisiensi sumber daya dengan mereduksi jumlah material yang digunakan dan mengurangi limbah produksi yang terbuang ke lingkungan. Hasil perhitungan produktivitas menunjukkan bahwa terdapat 3 aktivitas produksi dengan tingkat produktivitas terendah, yaitu sistem perendaman cengkeh sebesar 27,97%, pelintingan rokok sebesar 79,76% dan perajangan tembakau sebesar 80,13%. Solusi yang terpilih pada sistem perendaman cengkeh yaitu pembangunan instalasi pengolahan air limbah berupa biofilter. Pada sistem pelintingan rokok alternatif yang terpilih yaitu penggantian part mesin maker yang krusial seperti pisau pemotong, vacuum pad dan vacuum fan secara berkala. Sedangkan pada sistem perajangan tembakau terpilih alternatif pengolahan limbah gagang dan debu tembakau untuk dijadikan sebagai bahan campuran tembakau sehingga dapat melakukan efisiensi sumber daya. Alternatif-alternatif yang terpilih ini memberikan peningkatan produktivitas pada tiap sistem yang dilakukan perbaikan yaitu pada sistem perendaman cengkeh peningkatan produktivitas yang diestimasikan yaitu sebesar 32,85%, pada sistem pelintingan rokok diperkirakan peningkatan produktivitas yang terjadi sebesar 1,58% dan estimasi peningkatan produktivitas pada tahap perajangan tembakau yaitu sebesar 4,36%

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
