    LINGKUNGAN FISIK SITUS WONOBOYO DITINJAU DARI ASPEK GEOGRAFI

    No full text
    Situs Wonohoyo terletak di dataran aluvial kaki gunungapi Merapi. Berdasarkan pengamatan pedostratigrafi, situs ini tertimbun endapan lahar setebal rata-rata 2 m, dan di bawah endapan lahar ini telah terbentuk Tanah pada taraf yuvenil. Data geolistrik dan pemboran menunjukkan bahwa kawasan situs ini meluas ke arah utara hingga kawasan di utara jalan lingkar utara Desa Plosokuning. Pendekatan sistem perlu diterapkan untuk mengusahakan pengelolaan sumherdaya arkeologi. Berdasarkan masukan data geografi, diperoleh keluaran bahwa situs ini perlu dimasukkan ke dalam kawasan cagar budaya, sebab: (a) kawasan temuan ada di sempadan sungai yang harus dilindungi (b) kawasan ini termasuk subur, sehingga perkembangan permukiman lebih cepat daripada penelitian arkeologi: (c) kawasan ini merupakan daerah rentan bahaya aliran lahar dan gempa humi

    SISTEM AKUIFER DI LERENG GUNUNGAPI MERAPI BAGIAN TIMUR 0DAN TENGGARA (STUDI KASUS DI KOMPLEKS MATAAIR SUNGSANG BOYOLALI JAWA TENGAH)

    ABSTRAK Mataair-mataair di lereng Gunungapi Merapi yang merupakan sabuk mataair (spring belt) dalam era "kebutuhan air bersih yang tidak tercemar" menjadi incaran Perusahaan Air Minum (PAM) dan juga Pengusaha Air Minum Dalam Kemasan (AMDK). Pengambilan air langsung dari mataair ternyata sering menimbulkan konflik kepentingan petani pengguna air untuk pengairan. Banyak anjuran supaya pengambilan air tidak langsung dari mataair melainkan dengan mengebor dari akuifer. Tujuan dari penelitian sistem akuifer di sekitar mataair ini untuk mengetahui sistem akuifer sebagai dasar untuk menentukan lokasi pengeboran airtanah yang dapat digunakan untuk air bersih tanpa mengurangi debit air dari mataair. Metode penelitian menggunakan pendugaan geolistrik tahanan jenis (resistivity geoelectric), pengukuran mataair, dan pengamatan geologi dan topografi di sekitar mataair. Hasil dari penelitian menunjukkan bahwa mataair-mataair di daerah penelitian merupakan akuifer artesis yang keluar dari akuifer tertekan. Pemunculan mataair dari akuifer dapat diakibatkan oleh sebab, yaitu i) karena akuifer tertekan terpotong oleh depresi seperti mataair Cokrotulung dan Sigedang, (ii) karena akuifer tertekan oleh lapisan lempung seperti mataair Sungsang dan Nepen. Dengan diketahuinya sistem akuifer ini dapat ditentukan bahwa daerah antara S-2 sampai S-3 dan antara S-7 sampai S-8 dapat dibor sedalam 5 meter untuk mendapatkan sumur artesis

    Perusahaan Listrik Negara (PLN) membangun Pembangkit Listrik Tenaga Air (PLTA) di Kotopanjang Riau dengan membendung Sungai Kampar di Muara Lahat luas genangan direncanakan 124 km2 pada elevasi 85 meter (dpal). Pembangunan waduk ini memindahkan penduduk sejumlah 4.886 KK dari daerah genangan di samping itu genangan tersebut akan menenggelamkan sebagian dari area situs Candi Muara Takus. Tujuan penelitian ini adalah (1) mempelajari dampak genangan terhadap bangunan candi; (2) mencari alternatif untuk nrenanggulangi dampak yang terjadi. Metode survai, observasi lapangan dan pendugaan geolistrik digunakan dalam penelitian ini. Analisis data dilakukan diskriptif kuantitatif. Hasil penelitian ini menunjukkan bahwa ada 3 dampak hidrologis terhadap situs muara takus. (1) pada elevasi genangan 85 meter dpal akan menimbulkan air kapiler yang melernbabkan bangunan candi yang dibuat dari batubata. (2) air kapiler akan melembekkan lempung di bawah candi dan dasar candi akan melosok ke dalam tanah lempung (3) pada elevasi muka air waduk antara 83 in dpal dan 80 In dpal tebing sebelah barat yang berupa pasir kerikil dan pragmen batu akan mudah lepas dan longsor

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Get PDF
    We 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 text
    We 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
