Pemanfaatan Internet of Things Pada Pintu Dan Kipas Angin Otomatis Di Rumah Kos
Full text linkThe growth of society and students is getting higher from year to year, this is because it is inseparable from the development of the world of education, where people tend to control their home electrical appliances using switches manually that must be operated with human power. The use of technology that can be utilized from this internet network is to be able to access electronic equipment such as lights, fans, air conditioners and other electronic equipment in a room that can be turned on and off via smartphone. A prototype or model of a door that can be controlled remotely, meaning that the door can be opened and closed via a smartphone connected to a mobile phone. So the electronic devices that have been carried out research can be controlled via smartphones connected to the internet successfully carried out.Keywords: IoT, Wemos D1 Mini, Selonoid

Full text linkSalah satu faktor utama dalam budidaya ikan adalah pakan ikan, permasalahan dalam memberikan pakan ikan adalah biasa dilakukan secara manual dan berdasarkan kesempatan sama pemiliknya. Penelitian tentang pakan ikan hias semakin berkembang, diteliti dari berbagai komponen diantaranya, komunikasi jaringan, Mikrokontroller dan power supplay (menggunakan energi solar). Salah satu faktor utama dalam budidaya ikan adalah pakan ikan, Arduino uno adalah salah satu perangkat elektronik yang memili Memori, Otak dan Input serta output yang bersifat open source atau sumber terbuka, dimana setiap orang dapat berkontribusi dan dapat menggunakan secara bebas dan gratis. Tahapan pembuatan prototype dilakukan perancangan Blok diagram rangkaian sistem secara menyeluruh. Dimana dalam blok diagram ada hubungan masukan atau input dan adahubungan untuk keluaran atau output didalam sebuah sistem.
 
PROTOTIPE ALAT PEMBERI PAKAN IKAN BERBASIS INTERNET OF THINGS
Full text linkABSTRACT. Aquaculture technology is growing rapidly to improve the efficiency of fish farming, including catfish feed. The purpose of this study is to create an automatic feeding system using an ESP32 microcontroller and servo motor, and controlled by the Blynk application. This system is expected to provide feed regularly, accurately, and reduce feed waste. It is hoped that this technology will help in better catfish farming, reduce waste, and increase feeding efficiency. The results of the study showed that this system had a 95% success rate in feeding. Although this system is effective, it is necessary to overcome the dependence on a stable internet connection and the durability of the servo motor. Overall, this study shows that the use of Internet of Things (IoT) technology in aquaculture can increase productivity and significantly benefit catfish farmers.ABSTRAK.

Diharapkan bahwa teknologi ini akan membantu dalam budidaya lele yang lebih baik, mengurangi pemborosan, dan meningkatkan efisiensi pemberian pakan. Hasil penelitian menunjukkan bahwa sistem ini memiliki tingkat keberhasilan 95% dalam pemberian pakan. Meskipun sistem ini efektif, perlu diatasi ketergantungan pada koneksi internet yang stabil dan daya tahan servo motor. Secara keseluruhan, penelitian ini menunjukkan bahwa penggunaan teknologi Internet of Things (IoT) dalam akuakultur dapat meningkatkan produktivitas dan menguntungkan peternak ikan lele secara signifika
Low Power Consumption IoT Weather Monitoring System for Coastal Areas
Full text linkThis research aims to design and develop a real-time weather monitoring system in coastal areas using weather sensors integrated with Internet of Things (IoT) technology. This system wants to provide accurate weather information that fishermen can access directly through web-based platforms or mobile devices. Fishermen can make the right and safe decisions before going to sea, improving fishing activities' safety and efficiency. How to overcome the limitations of traditional weather monitoring methods that are manual, non-real-time, and discontinuous, and how to design systems that can transmit weather data automatically and in real-time in coastal areas that are often difficult to reach by power grids and stable internet. Another essential issue formulated is how to optimize the power consumption of sensor and communication systems so that they can operate efficiently using battery power resources for an adequate period. This study confirms the importance of energy efficiency in battery-based monitoring systems, especially in sensor nodes installed in remote locations without a fixed power source. The test results show the difference between the estimated operating time based on theoretical calculations and the results of simulations or real tests in the field. In idle mode, theoretical calculations estimate the system can last up to about 12.8 hours, but actual simulations show an endurance of about 7.3 hours. Meanwhile, in active mode, the estimated calculation is around 5.5 hours, while the simulation shows a slightly longer endurance, which is about 7.2 hours
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
