PENENTUAN INDEKS PENGUNAAN AIR (IPA) SEBAGAI SALAH SATU INDIKATOR HIDROLOGI PENILAIAN KESEHATAN DAERAH ALIRAN SUNGAI (DAS) DI DAS DODOKAN, PULAU LOMBOK, INDONESIA
Full text linkDalam penelitian ini penilaian kesehatan DAS dimaksudkan untuk mengkaji karakteristik hidrologi DAS menggunakan salah satu indikator hidrologi berdasarkan pedoman-pedoman monitoring dan evaluasi DAS di Indonesia yaitu Indeks Penggunaan Air (IPA). Indikator IPA dalam pengelolaan tata air DAS sangat penting kaitannya dengan mitigasi bencana kekeringan tahunan di DAS. Pehitungan IPA didasarkan pada perbandingan natar jumlah kebutuhan air total dan ketersediaan air DAS. Hasil penelitian menunjukkan nilai IPA DAS Dodokan termasuk dalam kategori sedang yaitu 0,25≤ IPA ≤ 0,75. Hal ini menunjukkan bahwa kebutuhan air di DAS Dodokan di beberapa keperluan masih bisa terpenuhi, namun perlu dilakukan konservasi air untuk menjaga kemungkinan defisit air
Penentuan Debit Lingkungan Di DAS Dodokan Berdasarkan Metode Tennant Dan Flow Duration Curve (FDC): Determination Of Environmental Flow In Dodokan Watershed Based On Tennant And Flow Duration Curve (FDC) Method
No full textThe Dodokan Watershed (DAS) is a watershed that is included in one of the national priority watersheds, so it is necessary to monitor and evaluate the watershed management on a regular basis. One very important aspect in monitoring and evaluating watershed management is the determination of the amount of environmental discharge. Environmental discharge in Indonesia is known as river maintenance flow which is intended in the context of river management to maintain river ecosystems. The amount of river maintenance flow in Indonesia is regulated in PP No. 38 of 2011 concerning rivers, namely Q95% mainstay discharge. The purpose of this study was to determine the amount of environmental discharge in the Dodokan watershed as one of the river management efforts in the future. The method used is the hydrological method, namely the Tennant method and flow duration curve (FDC). The Tennant method recommends that the minimum flow is set relative to the annual average flow and in the FDC method the daily discharge data is processed into a certain percentage as the probability value of the event using Weibull theory. The results showed that the environmental discharge interval using the Tennant and FDC methods was 0.01–0.2 m3/s, from this interval it can be seen that the flow characteristics in the Dodokan watershed have a very small minimum quantity. This situation illustrates that the carrying capacity of the Dodokan watershed is in a declining condition so it is necessary to carry out proper watershed management in accordance with existing condition

Tinjauan Empiris Evapotranspirasi Potensial Daerah Irigasi Parung, Kabupaten Lombok Tengah
Full text linkAbstrak: Tinjauan empiris evapotranspirasi potensial dilakukan sebagai salah satu tahapan dalam perencanaan dalam perkiraan kebutuhan air irigasi agar nantinya dapat menjadi salah satu usaha dalam pemenuhan pangan dari Daearah yang dilayani oleh sistem irigasi di Daerah Irigasi Parung. Kabupaten Lombok Tengah. Metode yang digunakan berupa metode empiris yaitu metode penmann modifikasi FAO. Hasil analisis menunjukkan bahwa nilai ET0 tertinggi terjadi pada bulan Oktober II yaitu sebesar 5,38 mm/hari dan nilai ET0 terendah terjadi pada bulan Juni III yaitu sebesar 2,59 mm/hari. b. besaran evapotranspirasi potensial dipengaruhi oleh parameter-parameter klimatologi seperti suhu udara, lamanya penyinaran matahari, radiasi matahari, kelembaban udara, dan kecepatan angin. terlihat bahwa parameter radiasi matahari, penyinaran matahari, dan kecepatan angin berbanding lurus dengan besaran evapotranspirasi potensial. Itu artinya apabila radiasi matahari, penyinaran matahari, dan kecepatan angin meningkat maka evapotranspirasi potensial juga akan meningkat. Sedangkan parameter kelembaban relatif dan suhu udara cenderung berbanding terbalik dengan besaran evapotranspirasi potensial. Itu artinya jika kelembaban relatif dan suhu udara meningkat maka besaran evapotranspirasi potensial menurun.
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
