Sistem GPS Pada Quadcopter Sebagai Pendeteksi Posisi Korban Bencana Banjir
No full textDaerah di Indonesia sudah seringkali dilanda banjir, dan selalu menimbulkan permasalahan, seperti menyebabkan korban jiwa hingga menimbulkan kerugian ekonomi. Banjir yang meluap hingga di jalanan dapat menimbulkan lumpuhnya jalur transportasi, oleh karena itu pada pencarian korban banjir dibutuhkan alat bantu berupa quadcopter. Quadcopter bisa diterbangkan pada area yang sulit dijangkau untuk menemukan korban yang selamat.
Untuk mengetahui posisi dari korban banjir, quadcopter menggunakan kamera yang mampu membantu pencarian korban. Kamera yang digunakan adalah thermal camera FLiR Lepton 2 mampu mendeteksi korban pada malam hari dan mampu membedakan antara makhluk hidup dan benda mati. Quadcopter juga menggunakan sistem GPS yang menggunakan GPS U-Blox Neo 6M. Pada saat kamera mendeteksi korban maka GPS mengirimkan data berupa koordinat dari posisi korban bencana banjir, GPS juga berfungsi untuk melacak koordinat lokasi pada quadcopter. Untuk menampilkan koordinat pada quadcopter, digunakan GUI (Graphic User Interface) yang telah diprogram melalui python 2.7 dan Pyqt. Quadcopter dikomunikasikan dengan menggunakan Wireless yang dilengkapi dengan adapter TL-WN722N.
Hasil dari penelitian ini adalah koordinat quadcopter dapat ditampilkan secara real time pada GUI yang telah dibuat dengan tingkat keakurasian GPS 99%. Menjangkau tempat yang luas dengan menggunakan wireless yang bisa menjangkau tempat kurang lebih 200m.

The area in Indonesia is often hit by floods Indonesia already, and
always cause problems, such as causing casualties to cause economic
losses. Floods that overflowed to the streets can pose of the crippled
public transportation, therefore on the search flood victims required
tools be quadcopter. Quadcopter flyable on hard to reach areas to find
survivors.
To know the position of the flood victims, the drones use a camera
that is capable of helping search victims. The camera used is thermal
cameras FLiR Leptons 2 capable of detecting victims at night and be
able to distinguish between living beings and inanimate objects.
Quadcopter also use GPS systems that use GPS U-Blox Neo 6 m. At the
moment the camera detects the victim then send data in the form of GPS
coordinates of the position of the victims of the floods, also serve to
track the GPS coordinates of the location at quadcopter. To display
coordinates at quadcopter, use the GUI (Graphic User Interface) which
has been programmed via python 2.7 and Pyqt. Drones are
communicated using the Wireless equipped with adapters TL-WN722N.
The results of this research are coordinates quadcopter can be
displayed in real time on the GUI has been created with GPS accuracy
rate of 99%. Reach out to a spacious place with using wireless can
reach places approximately 200 m
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 910-921. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Zucchini plants area annual plantas that area similar to pumpkins or eggplants whose fruit is harvested before ripe which belongs to the cucurbitaceae family. The purpose of this study was to determine and determine the effectiveness of Compound NPK Fertilizers and Guano Fertilizers which gave the best response to growth and increased production of zucchini (Cucurbita pepo L.) plants. The research has been carried out in one of the resident’s lands. Location in Perumnas Talang Kelapa Block 3 RT 61 NO. 41 RW 08 Alang-Alang Lebar Subdistrict, Palembang City, Sounth Sumatra in March until with May 2022. This study used a Split Plot Design with 9 treatment combinations which were repeated 3 times, resulting, in 27 treatment units with 3 sample plants. These are as follows: Main Plot For Compound NPK Fertilizer (N) consisting of 3 levels N1= 150 kg/ha, N2= 200 kg/ha, N3 = 250 kg/ha. Sub-plots for providing Guano Fertilizer (O)= terdin of 3 levels O1= 2,5 tons/ha, O2= 5 tons/ha, O3= 7,5 tons/ha. The variables observed were: plant height (cm), fruit diameter (cm), fruit length (cm), number of fruit per plot (fruit), fruit weight per plot (kg). The results showed that the treatment of compound NPK Fertilizer dosage of 250 kg/ha with Guano Fertilizer at a dose of 5 tons/ha gave the highest yield at fruit weight per plot 3,16 kg/plot or the equivalent of 6,32 tons/ha
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
