KELOPAK ROSELA (Hibiscus sabdariffa) TERHADAP KADAR
TRIGLISERIDA DARAH TIKUS PUTIH (Rattus norvegicus), Fakultas
Kedokteran, Universitas Sebelas Maret, Surakarta.
Berbagai penelitian di dunia telah membuktikan bahwa ekstrak kelopak
rosela (Hibiscus sabdariffa) dapat menurunkan kadar trigliserida darah, sedangkan
yang berkembang dalam masyarakat Indonesia adalah konsumsi kelopak rosela
dengan cara diseduh. Penelitian ini bertujuan untuk mengetahui adanya efek
seduhan kelopak rosela (Hibiscus sabdariffa) dalam mencegah peningkatan kadar
trigliserida darah tikus putih (Rattus norvegicus).
Penelitian ini bersifat eksperimental laboratorik dengan desain
Randomized Controlled Trial (RCT) yaitu pre test and post test controlled group
design, dilakukan di Laboratorium Biokimia Universitas Sebelas Maret Surakarta.
Subjek penelitian adalah tikus putih jantan (Rattus norvegicus) sebanyak 30 ekor,
strain Wistar, umur 3 bulan, berat badan kurang lebih 200 gram. Tikus-tikus
dibagi menjadi 3 kelompok secara random, masing-masing kelompok terdiri 10
ekor tikus. Semua kelompok diberi pakan tinggi kolesterol. Kelompok I sebagai
kontrol, sedangkan kelompok II dan kelompok III diberi seduhan kelopak rosela
dengan dosis 36mg/200gram BB/hari dan 54mg/200gram BB/hari. Semua tikus
diperiksa kadar trigliserida darahnya setelah masa perlakuan selama 28 hari
kemudian hasilnya dianalisa menggunakan uji ANOVA dan uji t berpasangan.
Dari hasil penelitian, dapat disimpulkan bahwa seduhan kelopak rosela
(Hibiscus sabdariffa) dapat mencegah peningkatan kadar trigliserida darah tikus
putih (Rattus norvegicus) secara signifikan (p<0,005). Sedangkan pemberian dosis
36mg/200gram BB/hari maupun dosis 54mg/200gram BB/hari tidak memberikan
perbedaan efek yang signifikan dalam mencegah peningkatan kadar trilgiserida
darah(p>0,005).

Species diversity and phylogenetic analysis of Heliconia spp. collections of Purwodadi Botanic Garden (East Java, Indonesia) inferred by rbcL gene sequences
Full text linkHapsari L, Trimanto, Wahyudi D. 2019. Species diversity and phylogenetic analysis of Heliconia spp. collections of Purwodadi Botanic Garden (East Java, Indonesia) inferred by rbcL gene sequences. Biodiversitas 20: 1266-1283. Heliconia L. is a single genus in the family Heliconiaceae, with approximate consists of 200 species. It has wide morphological variations among and within species which led to problems in species identification. Species diversity and phylogenetic analysis using morphology and rbcL marker subjected to 17 Heliconia spp. living collections of Purwodadi Botanic Garden (PBG) have been conducted. The rbcL gene located in chloroplast genome is one of appropriate proposed marker for plant barcoding assessment. This study aimed to study morphology and genetic variability of the PBG Heliconiaceae collections, to confirms the species name for a more accurate identity
record and to reveal the diversity and phylogenetics of the species. Morphological characterization showed high variability among Heliconia species, which included 3 subgenera (Heliconia, Stenochlamys, and Griggsia) and 1 hybrid. Each species possessed unique morphological characteristics. The common morphological characters which distinguished among and within Heliconia species includes leaf form, inflorescence type, and bract characteristics. Key to the Heliconia species examined is presented in this paper. However, molecular confirmation using rbcL sequences showed high conservation level (0.932) and low genetic variability. About 656
nucleotides were monomorphic and 33 positions were polymorphic which comprised 18 singleton variable sites and 15 parsimony informative sites. Twelve haplotypes were produced with haplotype diversity value 0.8952. Pairwise distance analysis shows that they
were shared high similarity of rbcL sequences with very low genetic distance (0.022 to 0.000). The topology of phylogenetic tree resulted by Neighbour-Joining algorithm has the best grouping and be able to explain the relationship among species of Heliconia, although supported by low bootstrap (65). It was separated into two clades following its subgen. classification. Clade 1 consists of subgen. Heliconia and Griggsia; while clade 2 consists of subgen. Heliconia and Stenochlamys; also hybrid species. Further, separation of deeper branchings (section) was inconsistent and unclear. Upon this study, rbcL marker was considered too conserved thus less valuable for phylogenetic analysis at lower taxa among and within Heliconia spp. However, rbcL was suggested to distinguish at higher level taxa between closely related genus and abov
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
