Effectiveness of Biochar application on the growth of red chili plants during the vegetative stage under waterlogging
No full textThe riparian wetland offers potential for horticultural crop cultivation, such as chili peppers. It is important to consider cultivation techniques and the use of organic matter to improve soil properties, particularly to combat waterlogging during the rainy season. This study aimed to assess the impact of biochar application on the growth of chili peppers (Capsicum annuum L.) during the vegetative stage under waterlogging conditions. This research was conducted at the experimental land of the Agrotechnology Department, Faculty of Plant and Animal Sciences, Universitas Bina Insan from December 2022 to February 2023. This research employed a complete randomized design (RAL) factorial with two factors. The first factor involved waterlogging stress, including control (C) and waterlogging stress (W). The second factor (N) encompassed the application of biochar, namely without biochar (N0), rice husk biochar (N1) and coconut shell biochar (N2) at a dose of 200 g plant-1. The results showed that waterlogging conditions (W) and biochar application (N) showed significantly different results in shoot length, root length, number of leaves, and total dry weight of chili plants, while the interaction (WxN) showed significantly different in shoot length and root length of plants. Treatment without biochar (N0) in waterlogging conditions actually showed shoot length, root length, number of leaves and total dry weight of plants that were significantly higher than treatment coconut shell biochar (N1) and rice husk applications (N2)
EFIKASI MIKROORGANISME LOKAL LIMBAH ORGANIK SEBAGAI BIOFERTILIZER ALTERNATIF DALAM MEMACU PERTUMBUHAN TANAMAN
Full text linkSalah satu aspek penting dalam budidaya tanaman adalah pemupukan. Pemupukan yang baik dan berimbang akan berdampak positif bagi kelangsungan tanaman. Penggunaan mikroorganisme lokal ekstrak daging keong mas pada media air kelapa, sebagai pupuk alternatif adalah bentuk teknologi tepat guna dalam mendukung konsep pertanian terpadu dan berkelanjutan. Penelitian ini bertujuan untuk mendapatkan produk formula mikroorganisme lokal ekstrak daging keong mas pada media air kelapa, yang mampu meningkatkan pertumbuhan tanaman. Percobaan ini menggunakan rancangan acak kelompok (RAK) dengan 5 perlakuan, yang terdiri atas kontrol positif (NPK Mutiara), Kontrol negatif (akuades) dan 3 perlakuan penyiraman dengan formula MOL. Indikator pertumbuhan tanaman yang diamati adalah tinggi tanaman, jumlah daun, panjang akar, diameter batang, berat basah dan kering tanaman. Data hasil penelitian dianalisis secara sidik ragam menggunakan aplikasi statistik 8, jika berbeda nyata maka akan diuji lanjut menggunakan LSD pada taraf 5%. Secara keseluruhan, hasil penelitian menunjukkan introduksi MOL ekstrak keong mas pada media air kelapa berbagai konsentrasi, mampu meningkatkan pertumbuhan tanaman. Masing-masing perlakuan memberikan efek yang berbeda dalam meningkatkan pertumbuhan. Analisis sidik ragam terhadap efektivitas Mol ekstrak keong mas pada media air kelapa berbagai konsentrasi sebagai pemacu pertumbuhan, didapatkan perlakuan B (konsentrasi 5%) sebagai perlakuan terbaik. Hal ini terbukti dari kemampuan konsentrasi tersebut dalam meningkatkan tinggi tanaman, panjang akar, berat kering dan basah tanaman tanaman mentimun. Oleh karena itu, perlakuan tersebut berpotensi untuk dikembangkan sebagai biofertilizer, pengganti pupuk kimia sintetis dalam memacu pertumbuhan tanaman dan pemenuhan kebutuhan pemupukan.Salah satu aspek penting dalam budidaya tanaman adalah pemupukan.

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
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
