Skripsi, Jurusan Geografi FIS Universitas Negeri Malang. Pembimbing: (1) Drs. Sudarno Herlambang, M.Si (II) Drs. J.P. Buranda M.Si Kata kunci: Karakteristik, Morfologi lorong, Sistem Perguaan Malang Selatan yang sebagai besar berupa daerah pantai sangat sesuai digunakan sebagai kawasan pariwisata. Namun pengembangan kawasan pantai di Malang Selatan masih sangat kurang sehingga dalam pengembangannya masih terhambat. Dengan temuan yang ada di dalam gua dapat meningkatkan kualitas dan kuantitas pengunjung yang ada. Temuan-temuan tersebut berupa ornamen gua dan bentukan lorong gua. Sistem perguaan Bagus-Jebrot tidak hanya sebatas penelusuran gua saja, namun dapat pula dijadikan sebagai kawasan ekowisata mengingat sistem perguaan ini dapat menunjang pariwisata di Pantai Jonggring Salaka. Sistem perguaan ini terdapat keberagaman ornament yang ada di dalam gua tersebut. Keberagaman tersebut dapat terlihat dari lorong sistem perguaan Bagus-Jebrot. Dengan demikian terlihat jelas terdapat keberagaman yang ada pada lorong gua berupa ornamen, ukuran dan karakteristik bentukan lorong Gua Bagus dan Gua Jebrot yang dapat menunjang kawasan ekowisata di gua tersebut. Namun, permasalahan data dan informasi mengenai keberagaman ornamen, ukuran, dan karakteristik bentukan lorong gua pada sistem perguaan Bagus-Jebrot masih sangat terbatas. Penelitian ini bertujuan mendeskiripsikan karakteristik morfologi lorong Sistem Perguaan Bagus-Jebrot. Diskripsi bentukan lorong-lorong gua, perhitungan mengenai lorong gua serta sebaran ornament yang ada di Gua Bagus-Jebrot Metode penelitian yang digunakan adalah survey. Berdasarkan jenisnya penelitian ini kualitatif dengan analisis spasial dan deskriptif. Sampel penelitian di dalam gua diambil pada setiap stasiun, sampel yang akan diambil meliputi tinggi lorong, lebar lorong pada setiap stasiun, kedalaman/kemiringan, ornamen gua dan panjang lorong. Hasil penelitian menunjukkan Sistem Perguaan Bagus-Jebrot merupakan gabungan dari Gua Bagus dan Gua Jebrot dengan enterence berupa lorong horizontal yang berada di lembahan. Elemen lorong yang dimiliki Sistem Perguaan Bagus-Jebrot berupa Single Conduit Passage dengan jenis elemen lorong Angulate Passage. Chamber yang terdapat pada Sistem Perguaan Bagus-Jebrot terdapat pada Gua Bagus dengan ketinggian 6,42 m dan 4 m. Sistem Perguaan Bagus-Jebrot berdasarkan klasifikasi Palmer (2003) memiliki pola morfologi lorong Curvilinear Branchwork. Berdasarkan klasifikasi Sweeting (1972) Sistem Perguaan Bagus-Jebrot merupakan gua yang termasuk ke dalam tipe Vadose Cave. Bedasarkan kondisi hidrologis lorong, Sistem Perguaan Bagus-Jebrot dapat dibagi menjadi 2 segmen yaitu lorong fosil dan vadose. Morfometri lorong Sistem Perguaan Bagus-Jebrot memiliki panjang Gua Bagus yang terpetakan 123,06 m dan Gua Jebrot yang terpetakan 289,73 m. Luas lorong Gua Bagus 548,54 m² dan Gua Jebrot 527,84 m². Volume Gua Bagus 4083,82 m³ dan Gua Jebrot 3575,43 m³. Luas area Gua Bagus 6347,43 m² dan Gua Jebrot 16937,62 m². volume spesifik Gua Bagus 33,19 m³/m dan 12,34 m³/m, kerapatan jaringan lorong Gua Bagus 51,58 m/m² dan Gua Jebrot 58,46 m/m², cakupan area Gua Bagus dan gua Jebrot sebesar 3,1%. Ornamen yang dapat ditemui di Gua Bagus yaitu Stalagmite, Stalactite, Coulumn/pillar, Flowstone, Gourdam, dan Soda straw. Gua Jebrot yaitu stalagtit, flowstone, dan gourdam
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
Speleogenetic process of Suaran Block, karst of Sangkulirang–Mangkalihat, East Kalimantan
No full textKarst of Sangkulirang Mangkalihat is one of the greatest karst areas in Indonesia and has hundreds of caves. Some of those caves are located at Suaran Block, one of the main karst block at this karst. This paper aims to study the speleogenesis process, as the fundamental process on karst landscape and cave development in that area. Speleogenetic process can be examined from the shape of the cave passage using uniformitarianism approach. That principle creates speleomorphology as the study of cave passage form and the factors that affect it. The examination of the cave passages uses cave maps to see the form and direction of them. As the result, caves at Suaran Block are formed mainly driven by geological structures such as fault – fissures and bedding plane which is indicated by linear form of the cave passage and water flow which shows sinusoidal form of the cave passage. Some caves are shaped by the combination of geological structure and water flows make them have mixed-induced speleogenesis
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
