STUDY OF CHEMICAL COMPOUNDS AND ANTIBACTERIAL ACTIVITY OF KEFA FOREST HONEY STORED AT DIFFERENT TIMES AGAINST THE BACTERIA AEROMONAS HYDROPILLA AND VIBRIO ALGINOLITYCUS
Full text linkThis research aims to determine the stability of the chemical compound content and antibacterial activity of kefa forest honey stored at different times, against the bacteria Aeromonas hydropilla and Vibrio alginolitycus which are pathogenic bacteria in fish farming. Tests for the chemical compound content of honey include testing for alkaloid compounds using the Culvenor-Fiztgerald method, saponins using the foam test, terpenes and steroids using the Lieberman-Burchard method, tannins using the addition of FeCl3 while flavonoids using the addition of HCl and Mg powder reagents. The total sugar content was measured using a spectrophotometer, the water content was measured using the gravimetric method and the pH using a pH meter. The antibacterial activity of honey was tested using the disc method without dilution. The research results showed that kefa forest honey taken at different times showed the same active compound content or did not change. The longer it is stored, the sugar, water and pH content of forest honey from Kefa decreases, but the decrease is not too big. Forest honey from Kefa, both new and stored for 6 months and 1 year, still has antibacterial activity against the bacteria A. hydropilla and V. alginolitycus.Penelitian ini bertujuan untuk mengetahui kestabilan kandungan senyawa kimia dan aktivitas antibakteri madu hutan kefa yang disimpan pada waktu yang berbeda, terhadap bakteri Aeromonas hydropilla dan Vibrio alginolitycus yang merupakan bakteri patogen pada budidaya ikan. Uji kandungan senyawa kimia madu meliputi uji senyawa alkaloid dengan metode Culvenor-Fiztgerald, saponin dengan uji busa, terpen dan steroid dengan Metode Lieberman-Burchard, tannin dengan penambahan FeCl3 sedangkan Flavanoid dengan penambahan Pereaksi HCl dan Mg Serbuk. Kandungan total gula diukur dengan menggunakan spectrofotometer, kandungan air diukur dengan metode Gravimetri dan pH dengan menggunakan pH meter. Pengujian aktivitas antibakteri madu dilakukan dengan metode cakram tanpa pengenceran. Hasil penelitian menunjukkan bahwa madu hutan kefa yang diambil pada waktu yang berbeda menunjukkan kandungan senyawa aktif yang sama atau tidak mengalami perubahan. Semakin lama disimpan, kandungan gula, air dan pH madu hutan asal kefa mengalami penurunan, namun penurunannya tidak terlalu besar. Madu hutan asal kefa, baik yang baru maupun yang telah disimpan selama 6 bulan dan 1 tahun tetap memiliki aktivitas antibakteri terhadap bakteri A.hydropilla dan V. alginolitycu
Data on GC/MS Elution profile, 1H and 13C NMR Spectra of 1-, 3-, and 6-Nitrobenzo[a]pyrenes
Full text linkThe data presented in this article is related to the research article entitled, “13C NMR Chemical Shift Assignments of Nitrated Benzo[a]pyrenes based on Two-dimensional Techniques and DFT/GIAO Calculations”, Kefa K. Onchoke, PeerJ., . The NMR spectral profiles of nitrated benzo[a]pyrenes is presented. Further, the article describes elution profiles of 1-, 3- and 6-NBaP, the acquisition of 1H and 13C NMR data and the J-Coupling constants (which are useful for the assignment of peaks via 2D HMQC and HMBC techniques). The data presented is useful for developing structure-activity relationships for other nitrated polycyclic aromatic hydrocarbons (NPAHs
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
Pemberdayaan Warga Jemaat GMIT Petra Kefa Dalam Perspektif Teologi Kewirausahaan (Studi Kasus Pengelolaan Lahan 10 Hektar)
Full text linkTujuan penulis melakukan penelitian ini untuk mengetahui dinamika perubahan berpikir di kalangan jemaat yang membuat jemaat GMIT Petra Kefa menjadi produktif berdasarkan teologi kewirausahaan.Metode yang dipakai adalah studi kasus terhadap pengelolaan lahan seluas 10 hektar.Selama ini, lahan yang dimiliki oleh GMIT Petra tidak dimanfaatkan sebaik mungkin sehingga menjadi lahan kosong yang dipenuhi rumput liar.Oleh karena itu. Menurut penulis, pemberdayaan jemaat yang dilakukan oleh GMIT Petra Kefa merupakan suatu lompatan baru yang seharusnya menjadi contoh bagi gereja lain di Klasis Timor Tengah Utara dalam merespon akan pergumulan jemaat di bidang ekonomi. Teknik pengumpulan data berupa observasi terarah dan wawancara.Hal ini dilakukan agar penulis dapat mengetahui pembahasan mengenai pemberdayaan warga jemaat GMIT Petra ditinjau dari Teologi Kewirausahaan. Kesimpulan yang didapat oleh penulis adalah faktor-faktor yang menyebabkan terjadinya dinamika perubahan berpikir di kalangan jemaat yaitu kepemimpinan yang transformatif, ketersediaan lahan yang masih kosong, ketersediaan air yang melimpah, semangat jemaat yang tinggi, belajar dari pola pelayanan Yesus yang tidak berfokus pada berdoa dan berkhotbah namun juga untuk mentransformasi kehidupan umatnya. Pemberdayaan jemaat dalam mengolah lahan gereja menjadi bukti bahwa ukuran suatu kesuksesan tidak terdapat pada jabatan tinggi dan sebagainya, melainkan bagaimana bekerja sesuai dengan talenta yang dimiliki.Temuan ini bersesuaian dengan teologi kewirausahaan yang menekankan soal kerja dan kewirausahaan.Untuk mengubah warga gereja dan masyarakat, gereja perlu mengembangkan sikap berwirausaha di kalangan warga gereja, dengan memanfaatkan kesempatan sebagai bentuk baru bersaksi melalui tindakan
The US is revisiting its trade relations with African countries: key issues on the table
Full text linkLast year, the US’s Biden administration announced plans to increase two-way trade and investment between the US and Africa. The starting point was a revamp of the Trump-era “Prosper Africa initiative”. As American secretary of state Antony Blinken visits three African nations – South Africa, Democratic Republic of Congo and Rwanda – Kefa Otiso and Francis Owusu provide insights into US-Africa trade relations and what’s being planned to improve them.This article is published as Otiso, K., and Owusu, F., (2022) “The US is revisiting its trade relations with African countries: key issues on the table” The Conversation, August 5; https://theconversation.com/the-us-is-revisiting-its-trade-relations-with-african-countries-key-issues-on-the-table-188230.under a Creative Commons license
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
