Pengaruh Kebisingan Terhadap Tingkat Konsentrasi Pada Pekerja Pemotongan Kayu di Kecamatan Arjasa Kabupaten Jember
Gangguan pada konsentrasi pekerja menyebabkan menurunnya
kemampuan pekerja dalam memusatkan perhatian pada pekerjaan yang dilakukan
sehingga dapat menyebabkan kecelakaan kerja. Salah satu faktor fisik penyebab
gangguan konsentrasi adalah kebisingan. Kebisingan juga terdapat di area kerja
industri. Salah satu industri yang memilki intensitas kebisingan yang tinggi adalah
industri pemotongan kayu. Salah satu industri pemotongan kayu di Kabupaten
Jember terletak di wilayah Kecamatan Arjasa. Kecamatan Arjasa memiliki
wilayah hutan produksi sehingga industri pemotongan kayu untuk dijadikan bahan
baku pembuatan plywood cukup berkembang di wilayah tersebut. Tujuan
penelitian ini adalah untuk menganalisis pengaruh kebisingan terhadap tingkat
konsentrasi pada pekerja pemotongan kayu di Kecamatan Arjasa, Kabupaten
Jember. Desain penelitian ini adalah analitik observasional dengan
pendekatan cross sectional. Penelitian ini dilaksanakan selama bulan Maret 2019
di 3 pabrik pemotongan kayu Kecamatan Arjasa Kabupaten Jember. Besar sampel
ditentukan menggunakan teknik purposive sampling dan didapatkan 32
responden. Hasil penelitian menunjukkan responden berusia antara 20-45 tahun
dan telah bekerja selama 1-5 tahun. Responden masih dalam kategori usia
produktif. Usia produktif menjadi pertimbangan pihak pabrik dalam memberikan
beban kerja karena pekerjaan pemotongan kayu memerlukan tenaga dan kondisi
kesehatan pekerja yang baik. Responden juga telah bekerja dalam masa kerja yang
cukup lama sehingga responden telah cukup lama terpapar dengan kondisi
lingkungan dalam pabrik terutama faktor kebisingan. Pengukuran intensitas
kebisingan pada pabrik pemotongan kayu menggunakan alat sound level meter
(SLM). Hasil pengukuran didapatkan rerata intensitas kebisingan dari 3 pabrik
pemotongan kayu untuk area pemotongan kayu sebesar 97,5 dB(A). Intensitas
kebisingan pada area pemotongan kayu lebih dari Nilai Ambang Batas (NAB) Kebisingan dalam lingkungan kerja industri yang telah ditetapkan sebesar 85
dB(A). Rerata kebisingan pada area bongkar muat sebesar 76,2 dB(A) sehingga
intensitas kebisingan pada area bongkar muat kurang dari NAB. Sumber utama
kebisingan pada pabrik pemotongan kayu berasal dari mesin gergaji. Tingkat
konsentrasi dinilai menggunakan Trail Making Test A (TMT A) dan Trai Making
Test B (TMT B) yang dinilai ketika responden telah bekerja selama 30 menit
sesuai sektor kerja responden. Hasil penilaian tingkat konsentrasi didapatkan
rerata TMT B:TMT A pada kelompok pekerja pemotong kayu sebesar 1,89 detik
sedangkan untuk kelompok pekerja area bongkar muat sebesar 1,28 detik. Tingkat
konsentrasi pada kelompok pekerja area bongkar muat lebih baik dibandingkan
dengan kelompok pekerja area pemotongan kayu karena pekerja area pemotongan
kayu membutuhkan waktu yang lebih lama untuk mengerjakan TMT A dan TMT
dibandingkan pekerja area bongkar muat. Waktu pengerjaan berkaitan dengan
proses konsentrasi baik dari proses penerimaan dan pengolahan informasi di
dalam thalamus. Uji statistik menggunakan indepent t test menunjukkan adanya
pengaruh kebisingan terhadap tingkat konsentrasi pada pekerja pemotongan kayu
di Kecamatan Arjasa Kabupaten Jember. Penurunan tingkat konsentrasi akibat
bising dapat diakibatkan oleh beberapa faktor yaitu intensitas kebisingan, usia,
masa kerja, riwayat kesehatan, dan adanya faktor stress akibat bising yang akan
mempengaruhi proses konsentrasi pekerja
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
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.
