Effect of Filtration Methods of Various Types of Adsorbents on the Quality of Coconut Shell and Kusambi Liquid Smoke as Raw Materials for Processed Meat Smoking
No full textIn this study, there were two groups, namely liquid smoke of kusambi and liquid smoke of coconut shells with various treatments of adsorbent filtration with 3 replications. There are three kind of treatment for each liquid smoke groups, first is liquid smoke without filtration process with adsorbent, liquid smoke with zeolite adsorbent treatment, liquid smoke with silica adsorbent treatment, and liquid smoke with activated charcoal adsorbent treatment. Analysis of variance showed that different types of liquid smoke and different adsorbent filtration had a very significant effect (P0.01) on antioxidants, total acid, specific gravity, tar, phenol content, pH, salinity, TDS, total yield, L* and b* color, hedonic color and smokey scent in the resulting liquid smoke. Analysis of variance showed that the different types of liquid smoke had no significant effect (P0.05), but the filtration treatment with different adsorbents had a very significant effect (P0.01) on viscosity. And the analysis of variance also showed that the different types of liquid smoke and the filtration of different adsorbents had no significant effect (P0.05) on the color a* of the resulting liquid smoke. The differences in the types of liquid smoke and the treatment of liquid smoke filtration with adsorbents had a very significant effect (P0 .01) on antioxidant, total acid, specific gravity, tar, phenol content, pH, salinity, TDS, total yield, L* and b* color, hedonic color, and smoke aroma in the liquid smoke produced. However, the different types of liquid smoke did not have a significant effect on the resulting viscosity (P0.05) and the different types of adsorbents in the liquid smoke filtration process had a very significant effect on the viscosity (P0.01). Meanwhile, the different types of liquid smoke and the different types of adsorbents in the liquid smoke filtration process did not have a significant effect on the value of the color a* or the reddish color of the liquid smoke (P0.05)
Pengaruh Pupuk Organik dari Sludge Padat Biogas Limbah Cumi-cumi dan Burung Puyuh Terhadap Produksi Nektar dan Bunga Sawi Hijau
No full textSawi hijau memiliki kemampuan untuk berbunga dengan durasi yang cukup panjang. Kemampuan tersebut juga membuat sawi hijau memiliki potensi yang besar sebagai pakan lebah. Namun adanya permasalahan antara banyaknya tumbuh bunga sawi hijau yang tidak searah dengan kualitas dari daging daun sawi hijau, membuat kesempatan lebah untuk memanfaatkan bunga sawi hijau sebagai sumber pakannya menjadi lebih singkat dikarenakan waktu panen sawi hampir bersamaan dengan tumbuhnya bunga sawi. Karena adanya permasalahan tersebut, dibutuhkan media tanam yang ramah lingkungan untuk mempercepat stimulasi bunga dan jumlah nektar pada bunga sawi hijau agar lebah dapat memanfaatkan bunga sawi hijau menjadi sumber pakannya dengan waktu yang lebih lama sebelum waktu panen sawi hijau tiba. Tujuan penelitian ini adalah untuk mengetahui efek dari penggunaan pupuk organik dari sisa pembuatan gas bio limbah cumi dan burung puyuh sebagai media tanam terhadap produksi nektar
dan pertumbuhan bunga dari sawi hijau dengan berbagai perlakuan kepada tanaman sawi hijau. Hasil penelitian ini diharapkan dapat berpengaruh terhadap pertumbuhan vegetatif dan generatif dari tanaman sawi hijau serta dapat meningkatkan produksi nektar dan bobot bunga dari sawi hijau.
Materi penelitian yang digunakan adalah pupuk limbah organik biogas dari cumi dan puyuh (Coturnix coturnix japonica L.) yang sudah berbentuk padatan. Polybag sebagai wadah untuk menanam sawi hijau. Timbangan digital analitik serta tisu untuk menimbang bobot dari bunga serta nektar yang diperoleh. Metode penelitian yang digunakan dalam penelitian ini menggunakan percobaan dengan Rancangan Acak Lengkap (RAL) yang terdiri dari enam perlakuan dan empat kali ulangan. Perlakuan yang digunakan adalah variasi. Perlakuan yang diberikan adalah variasi perbandingan konsentrasi media tanam dari limbah cumi dan puyuh yaitu, P0: varian kontrol tanpa adanya perlakuan; P1: 100% Limbah Puyuh; P2: 75% Limbah Puyuh + 25% Limbah Cumi; P3: 50% Limbah Puyuh + 50% Limbah Cumi; P4: 25% Limbah Puyuh + 75% Limbah Cumi, dan P5: 100% Limbah Cumi. Parameter utama yang diamati dalam penelitian ini adalah jumlah bunga pada tiap individu tanaman, jumlah produksi nektar bunga per bunga dan bobot bunga yang dihasilkan rata-rata per satuan bunga. Data dianalisis menggunakan ANOVA (Analysis of Variance), apabila terdapat perbedaan maka dilanjutkan dengan uji JND (Jarak Nyata Duncan).
Hasil penelitian menunjukkan bahwa variasi perbandingan konsentrasi pupuk organik dari limbah cumi dan puyuh memberikan pengaruh yang sangat berbeda nyata (P<0,01) terhadap jumlah bunga. Sedangkan pada bobot bunga, produksi dan produktivitas nektar variasi perbandingan
konsentrasi pupuk organik dari limbah cumi dan puyuh tidak memberikan pengaruh yang nyata (P>0,05). Hasil analisis ragam terhadap rata-rata jumlah bunga menunjukkan perbedaan yang sangat nyata (P0,05) yaitu P0 (0.00945 ± 0.0032), P1 (0.0111 ± 0.0035), P2 (0.0126 ± 0.0044), P3 (0.0127 ± 0.0014), P4 (0.01095 ± 0.0008), dan P5 (0.0442 ± 0.0027). Hasil analisis ragam terhadap bobot bunga sawi hijau menunjukkan tidak adanya perbedaan yang nyata (P>0,05) yaitu P0 (0,0223 ± 0,000580), P1 (0,0228 ± 0,000386), P2 (0,0235 ± 0,000445), P3 (0,0237 ± 0,000769), P4 (0,0240 ± 0,000259), P5 (0,0225 ± 0,001012). Serta hasil analisis ragam terhadap produktivitas nektar juga tidak menunjukkan perbedaan yang nyata (P>0,05) yaitu yaitu P0 (42,385 ± 14,108), P1 (48,823 ± 15,937), P2 (53,523 ± 18,322), P3 (53,651 ± 7,022), P4 (45,702 ± 3,505) dan P5 (48,967 ± 10,837)
Pemberian media tanam pupuk organik dari sludge padat biogas limbah cumi dan puyuh ini hanya memberikan efek terhadap pertumbuhan vegetatif dan generatif saja tanpa ada dampak yang diberikan kepada nektar yang dihasilkan. Pengukuran nektar disarankan dilakukan pada musim kemarau dan di daerah yang terkena intensitas cahaya matahari lebih lama agar optimal pengukurannya
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
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
