No full textLINDAWATI, Studi Pertumbuhan Pisang Barangan
(Musa acuminata, L.) Melalui Perlakuan Konsentrasi dan Lama Perendaman Kolkhisin.
Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi dan lama perendaman kolkhisin terhadap pertumbuhan dan perkembangan pisang barangan.
Penelitian ini dilakukan di l?samping Laboratorium Perbanyakan Tanaman Fakultas Pertanian Universitas Sumatera
Utara, Medan dari bulan Juli 2002 hingga Nopember 2002 dibawah bimbingan Bapak Ir. Emmy Harso Kardhinata, MSc selaku ketua pembimbing dan Bapak Ir. Hasmawi Hasyim, MS selaku anggota komisi pembimbing.
Rancangan yang digunakan adalah Rancangan Acak
Kelompok (RAK) Faktorial dengan 2 faktor yaitukonsentrasi kolkhisin yang terdiri dari 5 taraf yaitu konsentrasi 0 ppm, 1 ppm, 10 ppm, 20 ppm dan 30 ppm serta faktor waktu perendaman yang terdiri dari 3 faktor yaitu 1 jam, 2 jam, 3 jam.
Peubah amatan yang diamati adalah persentase pertumbuhan tunas, saat terbentuknya tunas, pertambahan tinggi tanaman, pertambahan jumlah daun, pertambahan diameter batang, pertambahan panjang daun, pertambahan lebar daun, dan ketebalan daun
Hasil penelitian menun jukkan bahwa perlakuan konsentrasi kolkhisin berpengaruhl nyata terhadap pertambahan jumlah daur. 11 MST tetapi berpengaruh tidak nyata terhadap pertambahan tinggi tanaman, diameter batang, panjang daun, lebar daun, saat terbentuk tunas dan ketebalan daun serta berpengaruh tidaknyata pada 13 MST untuk semua peubah amatan. Perlakuan lama perendaman berpengaruh nyata terhadap pertambahan tinggi Lanaman umur 5 MST dan jumlah daun 6 MST tetapi berpengaruh tidak nyata terhadap pertambahan diameter batang,panjang daun, lebar daun, saat terbentuk tunas dan ketebalan daun serta berpengaruh tidak nyata pada 13 MST untuk semua peubah amatan. Interaksi antara konsentrasi kolkhisin dan lama perendaman berpengaruh tidak nyata terhadap semua peubah amatan.119 HalamanSkripsi Sarjan
Analisis Permintaan Impor China terhadap Buah Manggis (Garcinia Mangostana L)
No full textPatricia Srisere Ikaria Situmorang (197039002) with the title of thesis “Analysis of Import Demand for mangosteen in China Market”. This research was supervised by Mrs. Sri Fajar Ayu, SP., MM., DBA as the head of the supervisory commission and Mrs. Dr. Lindawati, SP., M.Si as a member of the supervisory commision. This research study focus on the demand for mangosteen import in Chinese market involved three supplying countries, such as Indonesia, Thailand, and Malaysia. China is one of the largest importers of mangosteen in the international market. Thailand is a produce country and one of the largest mangosteen supply countries in the Chinese market (market leader). This study aims to analyze the demand system model and the percentage market share of the mangosteen fruit; analyze the factors that affect the market share of imported mangosteen fruit in the Chinese market; and analyze the competitive relationship of mangosteen from Indonesia, Thailand, and Malaysia based on the elasicity of demand in the Chinese market. This study used an econometric approach with the Almost Ideal Demand System (AIDS) model and used SAS application. The independent variabels used on this study were the price of mangosteen fruit imported from Indonesia. The results of the analysis show that the percentage of market share for Indonesia, Thailand and Malaysia is 26% each; 68%; and 6%. This research also shows that increasing market share can be seen from cross elasticity. The cross elasticity value between the price of Indonesian mangosteen fruit with Thai mangosteen fruit and Malaysian mangosteen fruit in the Chinese market is positive, this value indicates a substitute or competitive relationship. When Thailand or Malaysia are in a disadvantageous position (their import share is decreasing), there is an opportunity for Indonesia to enter the Chinese market to increase the share of mangosteen imports.109 HalamanTesis Magiste
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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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
