PERFORMA PERTUMBUHAN DAN KELANGSUNGAN HIDUP IKAN CAPUNGAN BANGGAI (Pterapogon kauderni) PADA MIKROHABITAT YANG BERBEDA
Get PDFIkan capungan banggai (Pterapogon kauderni) dikenal sebagai Banggai cardinal fish (BCF) merupakan ikan endemik perairan kepulauan Banggai, Provinsi Sulawesi Tengah, Indonesia. Tingginya jumlah ikan P.kauderni yang diperdagangkan menyebabkan kelestarian ikan ini terancam punah. Salah satu upaya dalam mengatasi masalah tersebut adalah mengoptimalkan kegiatan budidayanya. Penggunaan mikrohabitat yang sesuai dalam pemeliharaan ikan BCF akan memberikan performa pertumbuhan yang lebih baik. Tujuan dari penelitian ini adalah menentukan jenis mikrohabitat terbaik dalam mendukung pertumbuhan dan kelangsungan hidup ikan P. kauderni pada media pembesaran. Jevenil ikan P. kauderni (bobot 0.42±0.5 g, dan panjang 1.5±0.3 cm) merupakan hasil tangkapan dari alam. Sebanyak delapan ekor ikan dipelihara dalam setiap kerambah jaring apung yang telah diberi masing-masing dua pieces mikrohabitat (bulubabi, anemon, karang). Hal yang sama untuk perlakuan kontrol namun tanpa mikrohabitat. Setiap perlakuan diulang tiga kali. Hasil penelitian menunjukkan laju pertumbuhan harian, pertambahan biomassa dan kelangsungan hidup antar perlakuan mikrohabitat tidak berbeda secara signifikan (P>0.05), namun lebih tinggi dibandingkan kontrol (P<0.05). Mikrohabitat yang terbaik untuk pembesaran ikan P. kauderni adalah jenis bulubabi (Deademasitosum).

Prototype design of an IoT-based dryer and temperature monitoring device and test its utilization on the dryness and proximate levels of seaweed
Get PDFSeaweed has potential as a commodity for small and medium-scale businesses, but its quality is low due to conventional drying which experiences contamination and dries slowly. This research aims to produce a prototype IoT-based seaweed dryer to improve the quality of seaweed. The stages of this research are designing a prototype drying device, drying seaweed tests, and proximate analysis of seaweed. This research resulted in a 300W prototype using IoT components, including a solid state relay, Arduino Uno R3, potentiometer, thermocouple, 12C LCD, and SIM 800L V2 GSM GPRS module, with temperature control via an Android application. Optimal drying occurs at 60 oC, producing dried seaweed weighing 470.90 g from 1000 g. Water content decreases as temperature increases to 60 oC (18.85%), 50 oC (23.11%), 40 oC (32.30%), and conventional (34.50%). The highest protein, fat and carbohydrate content was at 60 oC, indicating drying efficiency at that temperature. Based on these results, it was concluded that using a dryer with a temperature of 60 oC was the best and most efficient.Keywords: Dryer; IoT; production; proximate; seawee
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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 PDFWe 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
