Water Feasibility Study of Bengawan Solo River for Irrigation: The Need for Technology to Solve Rice Field Pollution in Sragen, Indonesia
Full text linkThe aims of this study are to determine the feasibility of Bengawan Solo River water for irrigation of rice field in Sragen, Central Java and to find solution to the problem. The data used in this study were obtained from various literatures related to the issues discussed. The collected data were then selected and analyzed with descriptive argumentative. The result indicates that the water quality of Bengawan Solo River has dropped below the water quality standard grade IV according to Government Regulation Number 82 Year 2001. The use of water from this river has caused the quality of rice to decline below the rice quality standard according to Indonesian National Standard (SNI) 01.6128-2008 due to the bioaccumulation of heavy metals on rice crops, i.e. copper (Cu), mercury (Hg), cadmium (Cd), and Chromium (Cr) exceeded the threshold. Solution proposed to overcome this problem is with counseling programs to farmers conducted by relevant agencies on the use of rice field pollution control technology by physics, chemistry, and biology
Komposit Kitosan-Zeolit : Potensi Pemanfaatannnya sebagai Adsorben CO2
Full text linkThe world has paid special attention to the increasing of CO2 concentrations in the atmosphere. In climate change issue, CO2 gas as part of greenhouse gases plays an important role in controlling earth surface temperature. Several CO2 gas capture techniques have been reported. However, information on the utilization of potential natural materials as CO2 adsorbents is still small. This study aims to determine the potential of chitosan zeolite composites as CO2 adsorbents. Various literature is used to analyze the properties of zeolites, chitosan and the potential of chitosan- zeolite composites as CO2 adsorbents. The results show the possibility of utilizing zeolite-chitosan composites as CO2 adsorbents.
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
PEMBELAJARAN INVERTEBRATA MODEL PBM DENGAN MENGGUNAKAN MULTIMEDIA FILM DOKUMENTER DAN MULTIMEDIA ANIMASI DITINJAU DARI GAYA BELAJAR DAN KREATIVITAS (Studi Kasus Pembelajaran Porifera, Cnidaria dan Platyhelminthes Kelas X Tahun Akademik 2011 -2012 di SMA N Sragen Bilingual Boarding School)
Full text linkPenelitian ini bertujuan untuk mengetahui pengaruh model Pembelajaran Berbasis Masalah (PBM) yang diintegrasikan
dengan penggunaan multimedia film dokumenter dan multimedia animasi, gaya belajar, dan interaksinya terhadap prestasi belajar
siswa. Penelitian ini menggunakan metode eksperimen yang dilaksanakan pada bulan Januari-Mei 2012. Populasi penelitian ini adalah
semua siswa kelas X SMAN SBBS Tahun Pelajaran 2011/2012. Sampel diperoleh dengan teknik Cluster Random Sampling yang terdiri
dari atas dua kelas, yaitu X.A (PBM-Film Dokumenter) dan X.B (PBM-Animasi). Data dikumpulkan dengan metode tes antara lain: tes
kreativitas dan tes prestasi belajar ranah kognitif, non tes: lembar observasi hasil belajar ranah afektif dan psikomotor, an gket gaya
belajar siswa dan angket prestasi belajar ranah afektif dan psikomotor. Hipotesis diuji menggunakan anava. Berdasarkan hasil analisis
data disimpulkan: 1) terdapat pengaruh penggunaan multimedia terhadap prestasi belajar siswa ranah kognitif dan afektif, 2) terdapat
pengaruh antara siswa yang memiliki gaya belajar terhadap prestasi belajar siswa ranah kognitif dan afektif, 3) terdapat pengaruh
antara siswa yang memiliki kreativitas (tinggi rendah) terhadap prestasi belajar ranah psikomotor, 4) terdapat interaksi antara
penggunaan multimedia pembelajaran dengan gaya belajar terhadap prestasi belajar ranah psikomotor 5) tidak terdapat interaksi
antara penggunaan multimedia pembelajaran dengan kreativitas terhadap prestasi belajar siswa ranah kognitif, afektif dan psikomotor,
6) tidak terdapat interaksi antara gaya belajar dengan kreativitas siswa terhadap prestasi belajar siswa ranah kognitif, afektif dan
psikomotor 7) tidak terdapat interaksi antara penggunaan multimedia pembelajaran dengan gaya belajar dan kreativitas terhadap
prestasi belajar siswa ranah kognitif, afektif dan psikomotor.

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
