Pengembangan Sistem Cerdas Untuk Rekomendasi Pemupukkan Tanaman Salak Menggunakan Teorema Bayes dan Cohen’s Kappa
No full textSalak merupakan komoditas hortikultura unggulan di Indonesia, khususnya di Kecamatan Turi, Sleman, Yogyakarta. Tantangan utama dalam budidaya salak adalah praktik pemupukan yang kurang tepat akibat minimnya pemahaman petani terhadap kebutuhan nutrisi tanaman. Pemupukan yang salah dapat menurunkan kualitas dan kuantitas buah serta berdampak negatif pada kesehatan tanah. Penelitian ini dilakukan untuk mengembangkan sistem cerdas berbasis web yang mampu memberikan rekomendasi jenis pupuk secara tepat berdasarkan kondisi pertumbuhan dan gejala yang diamati pada tanaman salak. Teorema Bayes digunakan untuk melakukan inferensi probabilistik terhadap 8 jenis pupuk dan 12 gejala sebagai dasar pengambilan keputusan. Pengujian sistem dilakukan menggunakan metode Cohen’s Kappa dengan 17 data uji untuk membandingkan kesesuaian hasil rekomendasi sistem dengan pakar. Dari pengujian tersebut diperoleh 15 hasil sesuai dan 2 tidak sesuai, menghasilkan nilai Po sebesar 0,88235 dan Pe sebesar 0,14533. Nilai Cohen’s Kappa yang diperoleh sebesar 0,8623 menunjukkan tingkat kesesuaian yang sangat baik antara sistem dan pakar. Hasil ini menunjukkan bahwa sistem cerdas yang dikembangkan memiliki akurasi tinggi dan layak digunakan sebagai alat bantu rekomendasi pemupukan tanaman salak.Kata Kunci – Pemupukan ; Teorema Bayes ; Cohen’s Kapp
Perancangan Dashbord Visualisasi Efektivitas Platform E-Commerce untuk Pemasaran Hasil Pertanian Petani Milenial Kabupaten Sleman
No full textPenelitian ini bertujuan membangun dashboard visualisasi yang memudahkan analisis efektivitas platform e-commerce dalam pemasaran hasil pertanian oleh petani milenial. Teknik purposive sampling diterapkan dalam memilih responden, yang berusia 16 hingga 40 tahun dan telah menggunakan platform e-commerce selama minimal 6 bulan. Data dikumpulkan melalui kuesioner online dan offline dari 478 responden di 15 kecamatan Kabupaten Sleman. Dashboard dirancang berdasarkan KPI yang telah ditentukan, dari hasil observasi dan wawancara dengan komunitas petani milenial di Kabupaten Sleman. Terdapat tujuh Indikator KPI dalam dashboard visualisasi yakni: 1) Frekuensi penggunaan platform e-commerce, 2) Jenis platform e-commerce yang digunakan, 3) Kemudahan penggunaan platform, 4) Peningkatan penjualan setelah mengunakan platform, 5) Penilaian terhadap kualitas dukungan pelanggan, 6) Biaya dan Komisi dibandingkan keuntungan yang di peroleh dan 7) Fitur yang paling berguna dari platform e-commerce. Dalam perancangannya dashboard menggunakan metode prototyping mengunakan Figma dan framework laravel, menampilkan bar chart, pie chart, dan histogram yang dapat memberikan kemudahan bagi komunitas petani milenial dan pihak terkait dalam mengambil keputusan berdasarkan data yang ditampilkan.
Penerapan Metode Case Based Reasioning Pada Sistem Pakar Identifikasi Tingkat Kategori Alergi Susu Untuk Anak
No full textWorld Allergy Organization (WAO) melaporkan peningkatan sebesar 30-40 persen secara global, data yang sejalan dengan temuan dari Center for Disease Control and Prevention (CDC) yang mencatat peningkatan tiga kali lipat. Di Indonesia, beberapa penelitian mengindikasikan kenaikan sebesar 30% per tahun. Tujuan penelitian ini adalah mengembangkan aplikasi sistem pakar menggunakan metode Case Based Reasoning (CBR) untuk mengidentifikasi tingkat kategori alergi susu pada anak. Manfaatnya melibatkan pemberian identifikasi mandiri mengenai tingkat kategori alergi susu (berat, sedang, ringan) sebagai referensi awal sebelum konsultasi ke puskesmas atau dokter. Kesadaran orang tua tentang konsekuensi alergi susu, baik jangka pendek maupun panjang, menjadi krusial, untuk mengurangi dampak yang mungkin timbul di masa depan, terutama terkait pertumbuhan dan risiko stunting pada anak. Diolah sebanyak 3 data tingkat kategori alergi susu yakni tinggi, sedang dan rendah menggunakan metode Case Based Reasoning. Metode ini akan mengolah data berupa 12 gejala-gejala alergi susu yang terlihat pada anak , sehingga dapat melakukan identifikasi dan tindakan yang akan dilakukan. Hasil yang didapat dari seluruh kriteria similarity tingkat kategori alergi susu pada anak , termasuk kategori alergi susu tinggi dengan nilai similarity 72,72%
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
