KEANEKARAGAMAN JENIS HERPETOFAUNA DI RESORT TEGALLEGA DAN RESORT SARONGGE KAWASAN TAMAN NASIONAL GUNUNG GEDE PANGRANGO JAWA BARAT
Get PDFHerpetofauna Merupakan penjaga ekosistem dan penjaga keseimbangan rantai makanan di alam. Resort Tegallega dan Resort Sarongge merupakan desa yang memiliki kekayaan alam yang besar sehingga perlu adanya riset dan pemahaman tentang keanekaragaman jenis herpetofauna. Metode penelitian ini menggunakan Visual Encounter Survey yang dikombinasikan dengan Transek garis sepanjang 800 meter dengan tiga kali pengulangan untuk mengumpulkan data. Penelitian ini dilakukan pada bulan April sampai Juni 2021. Analisis data merujuk pada indeks ekologi berupa indeks Keanekaragaman, kelimpahan, kemerataan dan dominansi. Hasil data yang ditemukan di semua lokasi penelitian ditemukan 37 jenis dari 15 famili dan 33 genus. Indeks keanekaragaman di Resort Tegallega 5,114 dengan kriteria tinggi dan di Resort Sarongge 1,807 dengan kriteria sedang. Kesimpulan dari penelitian ini adalah faktor lingkungan yaitu suhu, kelembapan dan ph menjadi pengaruh besar untuk keberadaan herpetofauna, bukan hanya itu kerusakan lingkungan yang juga habitat dari herpetofauna juga menjadi pengaruh besar terhadap keberadaan herpetofauna
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
Pengaruh Penerapan Model CLIS (Children Learning In Science) Terhadap Keterampilan Proses Sains pada Materi Sistem Reproduksi
Get PDFPenelitian ini bertujuan untuk melihat pengaruh penerapan model CLIS terhadap keterampilan proses sains siswa pada materi sistem reproduksi. Penelitian ini dilakukan kepada siswa kelas XI SMA Negeri 92 Jakarta pada semester genap 2018/2019. Sampel diambil secara Cluster Random Sampling dengan responden sebanyak 60 siswa dari 2 kelas yaitu kelas eksperimen dan kelas kontrol. Metode penelitian menggunakan quasi eksperimen. Instrumen yang digunakan berupa 17 soal pilihan ganda yang mencakup lima indikator KPS (observasi, interpretasi, komunikasi, prediksi, dan mengajukan pertanyaan) untuk melihat pengaruh model CLIS terhadap KPS. Hasil penelitian menunjukkan nilai rata-rata KPS pada kelas eksperimen 82,4 dan 70,4 dikelas kontrol. Berdasarkan hasil uji prasyarat bahwa kedua kelas berdistribusi normal dan homogen. Sedangkan hasil uji hipotesis menunjukkan thitung > ttabel (5,47 > 2,39), maka dapat disimpulkan bahwa terdapat pengaruh penerapan model Children Learning In Science terhadap keterampilan proses sains
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
Dampak Pembangunan Resort Terhadap Keanekaragaman Jenis Amfibi (Ordo Anura) Di Kawasan Taman Wisata Alam (TWA) Telaga Warna Puncak Bogor Jawa Barat
Get PDFPenelitian ini bertujuan untuk mengetahui dampak dari pembangunan
resort terhadap keanekaragaman jenis amfibi (ordo anura) di kawasan Taman
Wisata Alam (TWA) Telaga Warna Puncak Bogor, Jawa Barat. Penelitian ini
dilaksanakan pada 6 April – 27 Juni 2019. Metode yang digunakan pada
penelitian ini adalah VES (Visual Encounter Survey). Pada penelitian ini
didapatkan 13 jenis amfibi pada kawasan Taman Wisata Alam. Kelimpahan jenis
di kawasan Taman Wisata Alam di dominasi oleh Chalcorana chalconota
78,81%. Pada Indeks keanekaragaman di kawasan Taman Wisata Alam
mendapatkan H’ = 0,929. Kekayaan jenis di Taman Wisata Alam sebesar DMg =
1,858. Indeks kemerataan jenis di masing-masing habitat diperoleh sebesar
Arboreal (A) 0,257, Terestrial (T) 0,667, dan Aquatik (AQ) 0,612. Pembangunan
resort (penginapan hexagonal, suite villa dan restoran) berdampak kepada
penurunan indeks keanekaragaman jenis amfibi H’ = 1,426 (2012) : H’ = 0,929
(2019) hal ini disebabkan dominasi jenis katak Chalcorana chalconota yang
menyebabkan tidak meratanya jumlah jenis katak di Taman Wisata Alam.
Diketahui bahwa Chalcorana chalconota merupakan salah satu jenis kodok yang
bertoleransi besar terhadap perubahan habitat; mereka dapat hidup di hutan primer
atau terganggu sampai kepada habitat buatan manusia
