KADAR KOLESTEROL DAN TRIGLISERIDA DARAH PADA DIABETES MELALUI PERLAKUAN EKSTRAK DAUN KLUWIH Artocarpus altilis Park (Blood Colesterol and Triglycerid Level on Diabetes with treatment of Breadnut (Artocarpus altilis Park) Leaf Extract)
Full text linkGangguan metabolism lipid atau dislipidemia berupa hipokolesterol dan hipertrigliserida biasa dijumpai pada penderita
Diabetes mellitus (DM), mengikuti adanya gangguan metabolism karbohidrat sebagai manifestasi utama penyakit diabetes, yang mana
dislipidemia tersebut dapat memacu timbulnya penyakit lain seperti jantung koroner dan aterosklerosis. Hasil dari beberapa penelitian
dan kajian pustaka menunjukkan bahwa daun kluwih diduga dapat menjadi alternative pengendali diabetes. Tujuan dari penelitian ini
adalah mengetahui kadar kolesterol dan trigliserida darah tikus putih (Rattus norvegicus L.) yang dibebani glukosa sebagai manifestasi
kondisi diabetic,setelah pemberian ekstrak daun kluwih Artocarpus altilis Park.
Penelitian menggunakan 12 ekor tikus putih yang dibebani glukosa 4,5 g/kg BB per oral. Tiap sampel dibagi dalam empat
kelompok yaitu K1 dibebani glukosa tanpa perlakuan, K2 glibenklamid, K3 jelompok uji ekstrak etanol daun kluwih dan K4 kelompok uji
ekstrak air daun kluwihPengukuran kadar kolesterol total darah dengan metode CHOD PAP dan kadar kolesterol total darah dengan
metode GPO PAP. Perlakuan dilakukan selama 14 hari. Data dianalisa secara statistic dengan program MINITAB 14 untuk mengetahui
pengaruh perlakuan pada tiap kelompok.
Hasil penelitian menunjukkan bahwa ekstrak daun kluwih dapat menurunkan kadar kolesterol dan trigliserida darah tikus putih
yang dibebani glukosa, dimana kedua bentuk ekstrak yaitu ekstrak etanol dan ekstrak air memiliki kemampuan relative sama dalam
menurunkan kadar kolesterol dan trigliserida.

MATERI PEMBELAJARAN BIOLOGI (BIOKIMIA) : DETEKSI FLAVONOID EKSTRAK DAUN KLUWIH (Artorpus altitis Park.) BIOLOGICAL LEARNING MATERIAL: DETECTION OF FLAVONOID FROM THE LEAF OF JACK FRUIT (Artorpus altilis Park.)
Full text linkThis research aimed to detect the flavonoid content from the leaf of jack fruit (Artocarpus altilis Park).
That leaf has medicinal aspect, since it can be used lo decrease the glucose from the blood circulation and act as
anti diabethic activii respectlvely. The detection of flavonoid was carried out by using thin layer chromatograplry (TLC) with steady phase of silica of GF 254 and lhe elluent ratio of chlorofurm: methanol of
98:2. The result obtained the preserce offavonoid complexes ol that leaf indicated by yellow spot and amoniac steam on the TLC. That result could enrich the biochemistry learning material toward student.
Key words: flavonoid detection, Artocarpus altilis Kar
Comparison of the quality of beef from Jagalan RPH Production and Non-RPH Production
No full textMeat quality is determined based on aspects of handling, inspection, environment and facilities at the slaughterhouse. Some of these aspects have been paid attention to by slaughterhouses (RPH), but they are still less of a concern for places that carry out independent slaughtering. The aim of this research is to determine the difference in the quality of meat from RPH production and meat from production other than RPH. Parameters used in meat quality testing include organoleptic tests (color, odor, consistency and cleanliness), pH tests and Water Holding Ability (DIA) tests. Data were analyzed using the Kruskal Wallis test, if there were significant differences, it was continued with the Mann Whitney test. The results showed that there were significant differences in color quality, consistency, pH and DIA values (P<0.05). Meanwhile, the results did not show significant differences in bau and cleanliness parameters (P>0.05). However, meat originating from both places is still at a level suitable for consumptio
Improving Evaluation Skills Through Flipped-Problem-Based Learning With Digital Storytelling Task: A Systematic Review
Full text linkEvaluation skills can assist students in effectively dealing with social, scientific, and practical problems. This study aims to review whether the Flipped-Problem Based Learning model with Digital Storytelling Task can improve evaluation skills. This research is a systematic review with the PRISMA method. Twenty-three articles were selected based on the inclusion criteria such as articles included in journals in the field of education and science for further analysis. The results of this study showed that the Flipped-Problem Based Learning with digital storytelling task can improve students’ evaluation skills which have the sub-skills of assess claims and assess arguments. This study concluded that the Flipped-Problem Based Learning model with Digital Storytelling Task can improve evaluation skills. This is because the syntax of Flipped-Problem Based Learning model and the step to create a Digital Storytelling are integrated to the indicators of evaluation skills

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
