Uji Laboratorium Microfertilizers Untuk Perkecambahan Benih Jelutung Rawa dan Padi
No full textDeforestasi lahan gambut telah menyebabkan berbagai bencana ekologis bagi lingkungan. Program rehabilitasi menggunakan penanaman spesies adaptif jelutung rawa (Dyera polyphylla) dan padi Inpara 2 (Oryza sativa), serta pemupukan diperlukan sebagai upaya percepatan pemulihan ekosistem gambut. Penelitian ini bertujuan untuk memproduksi formula pupuk mikro berbasis limbah kelapa sawit dan menganalisis pengaruh aplikasi pupuk mikro terhadap perkecambahan jelutung dan benih padi. Pupuk yang digunakan berupa mikrokarbon teraktivasi (MT), mikrokarbon non aktivasi (MNT), mikrolignoselulosa (ML), dan mikrokristalin (MK) yang berasal dari biomassa kelapa sawit dengan konsentrasi 1%, 3%, 5%, dan 7%. Penelitian ini menunjukan bahwa pupuk berpengaruh signifikan terhadap semua parameter dalam uji perkecambahan rawa jelutung dan berpengaruh signifikan terhadap sebagian besar parameter uji perkecambahan padi, kecuali parameter laju perkecambahan. Perlakuan MK 5% menghasilkan perkecambahan jelutung rawa terbaik, sedangkan MNT 1% menghasilkan perkecambahan padi terbaik.Peatland deforestation has caused various ecological disasters for the environment. The rehabilitation program uses the planting of adaptive species of swamp jelutung (Dyera polyphylla) and Inpara 2 paddy (Oryza sativa), as well as fertilization as an effort to accelerate the recovery of the peat ecosystem. This research aimed to produce microfertilizers formula based on palm oil waste and analyze the effect of microfertilizer application on the germination of swamp jelutung and paddy seeds. The fertilizers used are activated microcarbon (MT), non-activated microcarbon (MNT), microlignocellulose (ML), and microcrystalline (MK) derived from oil palm biomass with concentrations of 1%, 3%, 5%, and 7%. Fertilizers application significantly affected all parameters in the swamp jelutung germination test and significantly impacted most of the rice germination test parameters, except for the Mean Germination Time parameter. The MK 5% treatment produced the best
germination of swamp jelutung, while MNT 1% produced the best paddy germination.Tim PDUPT 202
Hubungan Budaya Organisasi Terhadap Organizational Citizenship Behavior pada Dosen Universitas Muhammadiyah Sumatera Utara
No full textOrganizational Citizenship Behavior (OCB) adalah sikap membantu yang
ditunjukkan oleh anggota organisasi, yang sifatnya konstruktif, dihargai oleh
perusahaan tapi tidak secara langsung berhubungan dengan produktivitas individu.
Tujuan penelitian ini adalah untuk mengetahui hubungan budaya organisasi terhadap
organizational citizenship behavior pada dosen univrsita muhammadiyah sumatera
utara
Pendekatan penelitian ini yaitu kuantitatif dan asosiatif dengan populasi
seluruh dosen UMSU, menggunakan teknik sampling non probability dengan metode
sampling insidental dimana jumlah semua populasi berjumlah 750 pegawai. Dengan
jumlah sampel sebanyak 150 orang. teknik pengumpulan data yang digunakan dalam
penelitian ini yaitu menggunakan angket (kuisioner).
Adapun yang menjadi hasil dari penelitian ini menunjukan bahwa ada
hubungan yang signifikan antara budaya organisasi (X) berpengaruh signifikan
terhadap variabel organizational citizenship behavior (Y) karena nilai t hitung bernilai
4,983 lebih besar dari t table yaitu 1,976 dan juga karena probabilitas sig 0,000 lebih
kecil dari α = 0,05. probabilitas sig 0,000 lebih kecil dari α = 0,05, dalam hasil regresi
sederhana menunjukan bahwa ada hubungan yang signifikan antara budaya
organisasi (X) terhadap organizational citizenship behavior (Y) dilihat dari taraf
signifikannya sig 0,000 lebih kecil dari α = 0,05 dan dari nilai determinasi yg bernilai
0.144 atau 14,4
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
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
