Pelabelan Harmonis Ganjil pada Kelas Graf Baru Hasil Operasi Cartesian Product
Graph class which has the characteristic of odd harmonious labeling is called as odd harmonious graph. Net graph is a graph which is gained by using operation Cartesian product of two line graphs. The construction of snake-net graph is inspired by the definition of snake graph replacing the round graph to net graph. In this paper, the study will show that snake-net graph fulfill the characteristic of odd harmonious graph in such a way snake-net graph is the odd harmonious graph. In the end of this paper, it is also shown that the union of snake-net graph is also called as the odd harmonious graph

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
The development of cartesian product operation of product fuzzy graphs and its properties
The product fuzzy graph is an extension of the fuzzy graph definition by replacing the minimum operation with the product operation. This research is qualitative research with research stages consisting of determining open problems, constructing new definitions, constructing new properties as theorems, and verifying results in the form of mathematical proofs. The purpose of this research is to get the Cartesian product definition of the product fuzzy graph and its properties. The results showed that the Cartesian product of two product fuzzy graphs is a fuzzy graph, the Cartesian product of two strong product fuzzy graphs is a strong product fuzzy graph, and the resulting Cartesian product of two complete product fuzzy graphs is a strong product fuzzy graph. Thus, the novelty of this research is that new properties of product fuzzy graphs are obtained
Tantangan pembelajaran matematika mobile problem based learning (mpbl) pada flipped classroom untuk membangun kemampuan berpikir kritis siswa
Siswa yang berpikir kritisnya mumpuni dapat mengambil suatu keputusan secara analitik, membangun kebiasaan yang tidak mudah langsung percaya terhadap suatu informasi yang beredar, dan mampu memecahkan permasalahan sehari-hari dengan berbagai cara yang berbeda. Agar didalam diri siswa terbangun kemampuan berpikir kritis, pembelajaran matematika harus dilaksanakan secara tepat misalnya dengan mengembangkan pembelajaran mPBL pada flipped classroom. Penelitian ini menggunakan metode sistematik literatur review untuk mengkaji tantangan model pembelajaran mPBL pada flipped classroom dalam membangun kemampuan berpikir kritis siswa. Pengumpulan artikel sebanyak 30 artikel pada jurnal nasional maupun internasional yang dicari melalui mesin pencarian google scholar serta scimago jr. Berdasarkan literatur yang dianalisis memberikan simpulan bahwa : (1) implementasi pembelajaran matematika dengan mPBL pada flipped classroom dapat membangun ketrampilan berpikir kritis siswa, dan (2) aspek akses jaringan internet, kepemilikan telepon seluler yang kompatibel, kompetensi guru dalam penguasaan teknologi komputer, inovasi guru dalam menyajikan pembelajaran melalui platform/LMS, pengembangan sumber belajar, alat ukur, dan buku kerja monitoring menjadi tantangan dalam pelaksanaan pembelajaran mPBL pada flipped classroom untuk membangun kemampuan berpikir kritis siswa
Appropriate Similarity Measures for Author Cocitation Analysis
We 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

Jenis penelitian ini adalah penelitian deskriptif dengan menggunakan pendekatan kualitatif. Pengambilan data dilakukan dengan metode tes dan wawancara. Peneliti mengambil tiga subjek untuk diwawancarai. Hasil penelitian ini menunjukkan bahwa terdapat empat jenis kesulitan yaitu: 1). Pada tingkat pemahaman, mahasiswa kesulitan memahami konsep tinggi dan alas jajargenjang. Alternatif pemecahannya dengan menggunakan model penilaian Assessment for Learning (AfL); 2). Pada tingkat penerapan, mahasiswa kesulitan menerapkan konsep kesebangunan bangun datar untuk menyelesaikan soal. Alternatif pemecahannya dengan model penilaian Assessment for Learning (AfL); 3). Pada tingkat analisis, mahasiswa kesulitan membuktikan rumus luas daerah segitiga dengan menggunakan pendekatan luas daerah jajargenjang. Alternatif penyelesaiannya dengan pembelajaran Process Oriented Guided Inquiry Learning (POGIL); 4). Pada tingkat evaluasi, mahasiswa kesulitan dalam memberikan penilaian terhadap suatu permasalahan disertai dengan alasan yang logis. Alternatif pemecahannya adalah dengan pembelajaran yang menggunakan model penilaian peer-assesment.
[English]: This study aims to diagnose undergraduate student’s difficulties in solving geometry problems based on Bloom's Taxonomy and find alternative solutions. This study is a descriptive study using qualitative approach. Data collection is conducted through test and interview. The subject of this study is 3 students. There are four difficulties found in this study, they are: 1). At the level of comprehension, the students are difficult to comprehend the concept of height and length of parallelogram. The alternative solution is to apply Assessment for Learning (AfL) model; 2). At the application level, the students have difficulty in applying the congruency concept of plane to solve the problem. The alternative solution is Assessment for Learning (AfL) model; 3). At the level of analysis, the students have difficulty in proving the formula of area of a triangle using parallelogram area. The alternative solution is to apply Process Oriented Guided Inquiry Learning (POGIL); 4.) At the evaluation level, the students have difficulty in providing assessment of a problem with a logical reason. The alternative solution is to use peer-assessment model of learning
