STATUS DAN KEMAMPUAN KESUBURAN TANAH SEBAGAI REKOMENDASI PERBAIKAN LAHAN DI BERBAGAI TINGKAT KEMIRINGAN LERENG DI KECAMATAN WONOSALAM KABUPATEN JOMBANG
Full text linkWonosalam sub-district is a productive land for wetland (paddy rice) and dryland (secondary crops and plantations) food crop cultivation that has been intensively cultivated for generations. The varied land use in Wonosalam allows a decrease in soil fertility. Soil fertility is not only influenced by soil properties, but also by slope. The decline in soil fertility in Wonosalam sub-district requires an evaluation of soil fertility status to provide appropriate land improvement recommendation efforts. This research aims to assess and monitor soil fertility in Wonosalam Subdistrict in order to find out which nutrients are limiting factors or constraints for a land. This research was conducted using the survey method at the time of sampling points and the soil test method. The soil chemical properties determined were Cation Exchange Capacity and Base Saturation, total P and total K, C-Organic. The results of the data obtained were then analyzed using matching and descriptive methods to determine soil fertility status and factors limiting soil fertility status. The results showed that in Wonosalam Subdistrict almost all land units have low fertility status criteria except for land units HK1 and TK1 which have medium fertility status criteria. The limiting factors of soil fertility status in Wonosalam Subdistrict are KB, C-Organic and K2O5 with land improvement efforts of dolomite lime, manure and K fertilize
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
Status Kesuburan Tanah Sebagai Rekomendasi Perbaikan Lahan Pada Berbagai Tingkat Kemiringan Lereng di Kecamatan Wonosalam Kabupaten Jombang
Full text linkKecamatan Wonosalam memiliki lahan budidaya yang telah diolah secara intensif secara turun temurun. Penggunaan lahan yang bervariatif di Wonosalam, memungkinkan terjadinya penurunan kesuburan tanah. Kesuburan suatu tanah selain dipengaruhi oleh sifat-sifat tanah, dipengaruhi juga oleh kemiringan lereng. Penurunan status kesuburan tanah di Kecamatan Wonosalam diperlukan kajian status kesuburan tanah untuk memberikan upaya rekomendasi perbaikan lahan yang tepat. Penelitian ini bertujuan untuk mengklasifikasikan status kesuburan tanah di Kecamatan Wonosalam untuk mengetahui faktor pembatas kesuburan tanah. Penelitian dilaksanakan dengan metode survei pada waktu pengambilan titik sampling dan metode uji tanah. Terdapat 12 titik sampling dari overlay peta penggunaan lahan, peta kemiringan lereng dan peta jenis tanah. Sifat-sifat kimia tanah yang ditetapkan yaitu Kapasitas Tukar Kation dan Kejenuhan Basa, kadar Fosfor total dan Kalium total, kadar Carbon Organik. Hasil data yang diperoleh kemudian dicocokkan dengan kriteria status kesuburan tanah untuk menentukan status kesuburan tanah dan faktor yang membatasi status kesuburan tanah di Kecamatan Wonosalam. Hasil penelitian menunjukan bahwa di Kecamatan Wonosalam hampir keseluruhan satuan lahan mempunyai kriteria status kesuburan rendah kecuali pada satuan lahan Hutan Kemiringan 8-15% dan Tegalan Kemiringan 8-15% mampunyai kriteria status kesuburan sedang. Faktor pembatas status kesuburan tanah di Kecamatan Wonosalam Kejenuhan Basa, Carbon Organik dan Kalium Total dengan Upaya perbaikan lahan pemberian kapur dolomite, pupuk kandang dan pupuk Kalium
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

Grounding adalah kecelakaan kapal yang disebabkan karena lunas atau
bagian paling bawah kapal bertabrakan pada dasar perairan sehingga kapal tidak
dapat berolah gerak akibat kapal tersangkut di dasar perairan. Proses ini dapat
terjadi secara sengaja atau tidak disengaja. Tujuan penelitian ini adalah untuk
mengetahui faktor, dampak dan upaya ketika KM.Vertikal mengalami grounding
di alur sungai Barito.
Peneliti menggunakan metode kualitatif karena mempunyai tujuan
menggambarkan proses terjadinya suatu peristiwa atau studi kasus dimana peneliti
melakukan pengumpulan data menggunakan teknik pengumpulan seperti
observasi, dokumentasi dan wawancara tentang faktor mengenai penyebab
KM.Vertikal mengalami grounding. Peneliti juga menggunakan teknik analisis
dengan diagram fishbone.
Hasil penelitian penyebab grounding KM.Vertikal di alur sungai Barito
adalah karena human error yaitu terjadinya kepanikan nakhoda ketika manuver di
alur sempit, kerusakan mesin pada pompa steering gear no.1 karena patahnya
spring solenoid valve dan faktor alam karena pasang surut belum mulai pasang.
Dampaknya mengakibatkan keterlambatan pengiriman muatan, kapal posisi
duduk di perairan alur pelayaran di sungai Barito dan kapal tidak dapat diolah
gerakan. Upaya setelah terjadi grounding adalah berlabuh jangkar, pengecekan
tangki, palka dan draft
