KARAKTERISTIK NATA HASIL FERMENTASI AIR CUCIAN BERAS
No full textAir cucian beras merupakan limbah pengolahan beras. Bahan limbah tersebut masih mengandung banyak senyawa tersuspensi seperti karbohidrat yang
sebagian besar terdiri dari pati sekitar 75%.Pati yang ada dalam air cucian beras dapat didegradasi menjadi gula sederhana dengan bantuan Aspergillus
oryzae. Sehingga gula tersebut dapat digunakan A. xylinum dalam memproduksi nata.Penelitian ini terdiri dari 2 bagian. Penelitian pertama yaitu penelitian
untuk melihat pengaruh keberadaan A. oryzae pada media produksi nata terhadap nata yang dihasilkan A. xylinum. Penelitian kedua (utama) bertujuan
untuk mempelajari pengaruh lama fermentasi A. oryzae dan konsentrasi penambahan gula pasir pasca fermentasi A. oryzae terhadap karakteristik nata yang
dihasilkanHasil penelitian menunjukkan bahwa fermentasi air cucian beras menggunakan A. xylinum tanpa menggunakan A. oryzae tidak menghasilkan
nata, sebaliknya fermentasi air cucian beras menggunakan A. xylinum dan A. oryzae mampu menghasilkan nata.Pada fermentasi A. oryzae selama 48 jam
menghasilkan nata dengan ketebalan, tekstur, nilai L dan berat basah lebih tinggi dibandingkan fermentasi selama 24 jam.Dari penambahan konsetrasi gula
pasir sebanyak 6 % menunnjukkan menghasilkan nata lebih tebal, nilai tekstur lebih tinggi (lebih kenyal), nilai L yang lebih tinggi dan lebih berat
dibandingkan penambahan konsentrasi gula pasir 0% dan 3%. Pada fermentasi A. oryzae selama 48 jam dengan penambahan gula pasir 6 % nilai berat,
ketebalan, tekstur dan warna didapat dengan nilai berturut-turut: 99.67 g; 220 mm; 507.67 g/5mm; 27.63 sedangkan pada fermentasi A. oryzae selama 24
jam dengan penambahan gula pasir 6 %, diperoleh nilai berat, nilai ketebalan, tekstur dan warna berturut-turut: 44.68 g; 200 mm; 421.55 g/5mm; 27.53
EVALUASI MUTU NASI HASIL PEMASAKAN BERAS VARIETAS CIHERANG DAN IR-66
No full textBeras sebagai komoditas pangan pokok dikonsumsi sebagian besar masyarakat Indonesia. Besar kecilnya konsumsi beras ditentukan oleh kualitas nasi
yang dihasilkan. Semakin pulen nasi yang dihasilkan cenderung lebih diminati oleh masyarakat. Hingga saat ini di Indonesia mutu tanak belum dijadikan
sebagai syarat dalam menentukan mutu beras, lain halnya dengan di dunia internasional yang merupakan persyaratan terutama dalam pengolahan beras. Sifat
dari mutu tanak lebih ditentukan oleh faktor genetik daripada perlakuan pasca panen. Tujuan penelitian ini untuk mengetahui pengaruh rasio beras dan air
terhadap kualitas nasi Ciherang dan IR-66, serta menganalisis mutu sensorik nasi dari varietas Ciherang dan IR-66 yang dimasak dengan rasio beras dan air
yang berbeda. Penelitian ini dilaksanakan di Laboratorium Kimia dan Biokimia Pangan Hasil Pertanian Jurusan Teknologi Hasil Pertanian. Tahapan
penelitian meliputi analisis kandungan amilosa dan amilopektin, mengukur lama pemasakan, daya rehidrasi, tekstur nasi, tingkat kepulenan (hedonik) dan
tingkat kesukaan terhadap kepulenan. Hasil penelitian menunjukkan bahwa: semakin tinggi rasio beras dan air, lama pemasakan nasi menjadi semakin
panjang, tekstur semakin lunak dan daya rehidrasi cenderung meningkat. Pada rasio beras dan air yang sama nilai kepulenan nasi Ciherang lebih tinggi
daripada IR-66 dan nilai kesukaan tertinggi terhadap kepulenan nasi Ciherang adalah pada rasio beras dan air 5:9, sedangkan IR-66 adalah 5:10
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
Bioconversion of Isoflavones Glycoside to Aglycone During Edamame (Glycine max) Soygurt Production using Streptococcus thermophillus FNCC40, Lactobacillus delbrueckii FNCC41, and L. plantarum FNCC26

soygurt production using Streptococcus thermophillus FNCC40, Lactobacillus delbrueckii FNCC41, and L. plantarum FNCC26.
Biodiversitas 21: 1358-1364. Due to its strong radical-scavenging and antioxidative activity, isoflavones in soybeans have received
great attention for the development of functional foods. This study focused on bioconversion of isoflavones glycoside into its aglycone
form of edamame green soymilk fermented with three lactic acid bacteria (LAB), i.e., S. thermophilus FNCC40, L. bulgaricus FNCC41,
and L. plantarum FNCC26 to produce soygurt. Green soymilk was fermented with 6% (v/v) of LABs as a starter culture for 24 hours at
37ºC. Its antioxidative activity were measured using DPPH free radical scavenging activity method. Daidzein and genistein released
during fermentation were fractionated using HPLC and detected further by LCMS to confirm the presence of these two substances. The
results showed that the population density of starter culture in green soymilk reached 10
9
CFU/mL, and the pH decrease from 6.8 to 3.5.
All LABs cultures used in the fermentation process were able to produce free aglycone, releasing more daidzein and genistein.
Increasing daidzein and genistein content in soygurt results in increasing antioxidative activity. The highest antioxidative activity (IC50 =
41.01 mg/mL) was found in the soygurt fermented with S. thermophilus FNCC40. This finding indicates that S. thermophilus FNCC40,
L. bulgaricus FNCC41, and L. plantarum FNCC26 are potential as an effective starter culture to produce a soygurt with good
antioxidant activity
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
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
