GAMBARAN TELUR NEMATODA USUS PADA KUKU PETUGAS SAMPAH DI TEMPAT PEMBUANGAN AKHIR (TPA) SAMPAH CIANGIR KELURAHAN KOTA BARU KECAMATAN CIBEUREUM KOTA TASIKMALAYA
Get PDFSampah merupakan masalah yang tak pernah terselesaikan hingga saat ini, meskipun beberapa negara maju telah menindak tegas orang-orang yang suka membuang sampah sembarangan, namun belum juga membuat para pembuang sampah sembarangan menjadi jera, apalagi dengan negara berkembang yang bahkan belum memiliki undang-undang yang jelas mengenai permasalahan ini.Metode penelitian bersifat deskriptif, dan dilakukkan terhadap 30 orang petugas sampah, dilaksanakan di laboratorium STIKes BTH Tasikmalaya dengan metode pemeriksaan sedimentasi.Dari hasil penelitian diketahui bahwa dari kotoran kuku petugas sampah di Tempat Pembuangan Akhir Ciangir.Kelurahan Kota Baru Kecamatan Cibeureum Kota Tasikmalaya, terdapat 25 sampel negatif dan 5 sampel positif, dengan presentase 16,67 % yang mengandung telur cacing Nematoda Usus. Jenis telur cacing yang ditemukan adalah Ascaris lumbricoides dan 83,33 % sampel yang negatif
DAYA HAMBAT INFUSUM DAUN SEMBUNG (Blumea balsamifera) TERHADAP PERTUMBUHAN BAKTERI Escherichia coli DENGAN METODE DIFUSI CAKRAM
Get PDFDaun sembung (Blumea balsamifera) merupakan salah satu tanaman yang bisa dimanfaatkan sebagai obat tradisional. Zat aktif yang terdapat dalam daun sembung (Blumea balsamifera) antara lain tanin dan saponin yang berfungsi sebagai antibakteri. Tujuan dari penelitian ini adalah untuk mengetahui konsentrasi daya hambat infusum daun sembung (Blumea balsamifera) terhadap pertumbuhan bakteri Escherichia coli.Variasi konsentrasi infusum dibuat dengan rentang 10%-100% dengan kepadatan bakteri 3x108 /ml. Metode yang dipakai pada penelitian ini adalah metode Kirby-Bauer.Dari pengamatan diketahui infusum daun sembung (Blumea balsamifera) dapat menghambat pertumbuhan bakteri Escherichia coli pada konsentrasi 90% yaitu 4,2 mm.Kesimpulannya bahan infusum daun sembung (Blumea balsamifera) memiliki daya hambat terhadap pertumbuhan bakteri Escherichia coli
Gambaran Diff Count Pada Perokok Di Kecamatan Cibeureum
Get PDFKeberadaan zat-zat beracun dari asap rokok menyebabkan tubuh melakukan perlawanan terhadap terjadinya respon imun dimana leukosit menjalankan sebagian besar fungsinya di luar sistem peredaran darah yaitu memperlihatkan gerakan aktif dan sebagian mempunyai daya fagositosis. Gerakan yang diperlihatkan adalah suatu proses merangkak atau amuboid pada substrat bahan kimia pada asap rokok dapat menyebabkan inflamasi paru.Penelitian ini bertujuan untuk mengetahui gambaran jenis sel leukosit yang terdapat pada perokok. Karena zat-zat yang terkandung dalam rokok merupakan zat-zat yang berbahaya yang dapat mempengaruhi sel leukosit.Metode penelitian bersifat deskriptif, dengan teknik pengambilan sampel random sampling pada perokok di Kecamatan Cibeureum.Hasil penelitian menunjukkan adanya peningkatan distribusi jenis leukosit antara lain adanya peningkatan monosit, neutrofil dan limfosit. Dengan demikian maka dapat disimpulkan gambaran Diff Count pada perokok di kecamatan Cibeureum terjadi peningkatan pada beberapa jenis leukosit
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
