No full textLocal Food Crops and the Poor (The Case of the Three Geographical Regions of Kulon Progo Regency)
Get PDFIt is believed that local food crops are available widely in rural regions. However, not all of the people consume them. The facts also show that local food crops are placed as secondary sources of foodstuff. This research aims at (1) describing the profile of local food crops consumed by the poor rural households and 2) exploring causes and mechanism of the poor rural household in maintaining local food crops as their food sources in the three different geographical regions of Kulon Progo Regency, namely the upland region, the transitional region, and the lowland region of Kulon Progo Regency. A household survey is conducted to achieve the above mentioned objectives. Respondents of this research arechosen purposively from the poor households’ data as listed by the Kulon Progo Regional Planning Board to represent the three regions in the regency. Three districts in the regency are selected to represent the three types of regions respectively, i.e: Samigaluh, Pengasih, and Lendah. A questionnaire is distributed in order to collect the data from the selectedhousehold respondents. The findings of this research are (1) there are various kinds of local food crops that were consumed by the respondents from three different geographical regions. The researchers collected that there were 36 types of local food totally from these three geographical regions, (2) there were also several motives that were important to be described in order to explained the reason why the respondents processed local food crops such as to be sold or to be consumed by themselves, (3) spatially, there are a specific pattern of harvested local food crops based on the respondents perceptions in three geographical areas: (i) based on nature, and (ii) based on human decision , (4) there were also various methods of utilisation local food crops, such as boiled, fried, steamed, cooked into intermediate products, or cooked into final commodities that were ready to be consumed

Penelitian ini bertujuan untuk mengetahui hasil dan kualitas benih kacang hijau yang ditanam secara tumpangsari dengan jagung manis dibandingkan monokultur, serta mengetahui komposisi jumlah baris optimal pada tanaman kacang hijau yang ditanam secara tumpangsari dengan jagung manis. Penelitian dilakukan di Kebun Percobaan Banguntapan dan Laboratorium Teknologi Benih, Fakultas Pertanian, Universitas Gadjah Mada, Yogyakarta pada bulan Juni - Oktober 2014. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap dengan 6 perlakuan yang diulang sebanyak 3 kali. Perlakuan ini terdiri atas kombinasi jumlah baris kacang hijau : jagung manis, yaitu 3:1, 4:1, 5:1, 6:1. Pengamatan dilakukan terhadap komponen pertumbuhan kacang hijau, komponen hasil kacang hijau, kualitas benih kacang hijau, dan Land Equivalent Ratio (LER). Hasil penelitian menunjukkan bahwa tumpangsari kacang hijau dengan jagung manis memberikan pertumbuhan dan kualitas benih kacang hijau yang sama baiknya dengan pertanaman monokultur. Pola pertanaman tumpangsari 4, 5, dan 6 baris diikuti dengan 1 baris jagung manis memberikan hasil persentase polong isi/tanaman serta jumlah biji/polong kacang hijau yang sama baiknya. Pola pertanaman tumpangsari 3, 4, 5 dan 6 baris diikuti dengan 1 baris jagung manis juga memberikan hasil benih kacang hijau yang sama baiknya terhadap komponen jumlah polong/tanaman serta berat benih kering/hektare kacang hijau. Pola pertanaman tumpangsari 6 baris kacang hijau diikuti dengan 1 baris jagung manis direkomendasikan karena memiliki LER > 1
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
Pertumbuhan dan Hasil Benih Lima varietas Cabai Merah (Capsicum annum L.) di Dataran Menengah
Get PDFoai:journal.ugm.ac.id:article/1345Lima varietas cabai merah, yaitu Branang, Gantari, Lokal Pakem, Lembang-1, dan Kusuma dilihat pertumbuhan dan hasil benihnya dari bulan Desember 2011 hingga Mei 2012. Percobaan lapangan dilaksanakan di Dusun Pandanpuro, Desa Hargobinangun, Kecamatan Pakem, Kabupaten Sleman pada ketinggian 505 m diatas permukaan laut. Penelitian disusun dalam rancangan acak kelompok lengkap dengan empat ulangan. Unit percobaan terdiri dari 60 tanaman dengan jarak tanam 50 cm x 50 cm. Tujuan dari penelitian ini adalah untuk mengetahui pertumbuhan dan hasil benih lima varietas cabai merah di dataran menengah. Data hasil pengamatan dianalisis dengan sidik ragam pada tingkat kepercayaan 95%, dan untuk mengetahui perbedaan diantara perlakuan dilakukan dengan Uji Jarak Ganda Duncan (Duncan’s Multiple Range Test) pada tingkat kepercayaan 95%. Untuk mengetahui hubungan antara dua variabel dilakukan analisis korelasi sederhana. Hasil penelitian menunjukkan bahwa lima varietas cabai merah memiliki pertumbuhan dan hasil benih yang berbeda di dataran menengah. Cabai merah keriting varietas Lembang-1 mempunyai pertumbuhan terbaik dan hasil buah tertinggi (10,22 ton/ha), diikuti oleh Kusuma (8,71 ton/ha), kemudian Lokal Pakem (7,37 ton/ha). Cabai merah besar varietas Gantari mempunyai pertumbuhan terbaik dan hasil buah tertinggi (8,5 ton/ha) dibandingkan dengan varietas Branang (6,5 ton/ha). Cabai merah keriting varietas Lembang-1 mempunyai hasil benih tertinggi (46,12 gram/tanaman), diikuti oleh Kusuma (37,21 gram/tanaman), dan Lokal Pakem (25,28 gram/tanaman). Hasil benih cabai merah besar varietas Branang (29,62 gram/tanaman) lebih baik dari pada varietas Gantari (28,05 gram/tanaman). Nilai komersial dari cabai merah adalah rasa pedas. Kadar capsaicin berpengaruh terhadap tingkat kepedasan. Kadar capsaicin tertinggi dimiliki oleh cabai merah keriting varietas Kusuma (1,12%) dan Lokal Pakem (0,91%) dibandingkan dengan ketiga varietas cabai merah lainnya
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
