Faktor II.Lama Penyimpanan (P) dengan 5 taraf yaitu: P0 : Tanpa Penyimpanan Pj. : 2 Minggu Penyimpanan P2 : 4 Minggu Penyimpanan P3 : 6 Minggu Penyimpanan p4 : 8 Minggu penyimpanan Masing-masing kombinasi perlakuan diulang sebanyak 3 kali Parameter yang diamati adalah kadar air benih (%), persentase benih berkecambah dalam penyimpanan (%), persentase perkecambahan {%), persentase kecambah normal (%), laju perkecambahan (%/hari), tinggi kecambah (cm), bobot segar kecambah (g) dan pola perkecambahan. Hasil penelitian yang diperoleh menunjukkan bahwa suhu penyimpanan berpengaruh nyata terhadap kadar air benih, persentase perkecambahan, persentase kecambah normal, laju perkecambahan, tinggi kecambah dan bobot segar kecambah. Lama penyimpanan berpengaruh nyata terhadap kadar air benih, persentase perkecambahan, persentase kecambah normal, laju perkecambahan, tinggi kecambah dan bobot segar kecambah. Interaksi antara suhu penyimpanan dan lama penyimpanan berpengaruh nyata terhadap persentase perkecambahan dan laju perkecambahan, berpengaruh tidak nyata terhadap kadar air benih, persentase kecambah normal, tinggi kecambah dan bobot segar kecambah.90 HalamanSkripsi Sarjan

Analisis Kebutuhan Pengembangan E-Modul Bermuatan Video Pembelajaran pada Pendidikan Jarak Jauh bagi Calon Guru Fisika
Full text linkDistance Education (PJJ) as a learning solution during the COVID-19 pandemic at the University of Lampung has not been implemented optimally. The purpose of this study was to find out the circumstances and needs of prospective physics teacher students while carrying out PJJ online from their respective homes. As well as analyzing the materials and assignments to achieve the Subject Learning Outcomes (CPMK) of Educational Research Statistics. This study uses a descriptive analysis method with a research instrument in the form of a questionnaire distributed online with the help of a google form. The sample in this study was 53 students of physics teacher candidates in the Physics Education Study Program, University of Lampung. The results of this study indicate that the condition of students in implementing PJJ is that they already have adequate facilities both from electricity infrastructure, internet networks, devices, and getting support from family. However, students find it difficult to understand practical learning when using media and learning methods that are not varied. The analysis of materials and tasks developed from CPMK Educational Research Statistics consists of three main materials with ten learning videos, and each student is asked to complete matters an educational research case using SPSS. Based on the results of this needs analysis, lecturers need to develop a teaching material, namely an e-module containing learning videos that can facilitate prospective physics teacher students in implementing PJJ
ANALISIS DAMPAK PANDEMI COVID-19 TERHADAP KESEHATAN FISKAL KABUPATEN/KOTA DI PROVINSI SUMATERA BARAT
Full text linkPenelitian ini bertujuan untuk mengetahui tingkat kesehatan fiskal sebelum dan pada saat terjadinya pandemi covid-19 serta menganalisis indikator yang berpengaruh terhadap kesehatan fiskal Pemerintah Kabupaten/Kota di Provinsi Sumatera Barat. Pengumpulan data diambil dari Laporan Keuangan Kabupaten/Kota di Provinsi Sumatera Barat tahun 2019 - 2020. Seluruh populasi dalam penelitian ini dijadikan sampel sehingga diperoleh 19 Laporan Keuangan. Analisis komparasi yang digunakan sebagai teknik dalam melakukan analisis dan menguji hipotesis. Berdasarkan uji komparasi dapat disimpulkan terdapat perbedaan yang signifikan pada tahun 2018-2019 sebelum terjadi covid-19 dengan tahun 2020-2021 pada saat terjadi covid-19. Pada saat sebelum terjadi covid-19 terdapat 3 Kabupaten/Kota kategori baik 16 lainnya kategori cukup namun pada saat terjadi pandemi covid-19 seluruh Kabupaten/Kota kategori cukup
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
