RANCANGAN MESIN SEPARATOR SAMPAH MENGGUNAKAN TEKANAN DAN PERBEDAAN MASSA JENIS
Full text linkUmunya orang membuang sampah pada satu wadah, sehingga sampat menjadi tercampur dan sulit untuk didaur ulang. Penelitian ini bertujuan menghasilkan mesin pemisah sampah. Kinerja mesin dalam memisahkan limbah terdiri dari dua tahap, yaitu (1) proses penguraian limbah campuran dengan menggunakan tekanan air dalam tabung silinder, (2) pemilahan limbah menggunakan hit air yang terjadi karena tekanan air menyembur melalui nosel ke dalam tabung dan perbedaan massa jenis air dengan limbah. Hasil pengujian mesin menunjukkan bahwa tekanan air yang disemprotkan oleh nozzle dalam tabung silinder secara efektif menggambarkan limbah. Fenomena riak air dan perbedaan dalam kepadatan jenis air dengan sampah membuat kepadatan berat jenis air lebih ringan daripada air mengapung (contoh: plastik, anorganik) disuplai ke kategori ringan dari wadah limbah anorganik. Limbah padat dari jenis yang sama dengan air (contoh: botol air mineral, anorganik) mengambang di tengah tabung silinder yang disalurkan ke wadah limbah anorganik sedang. Sampah yang beratnya lebih berat daripada air (contoh: sisa makanan, daun, organik) dikubur di bawah tabung silinder yang didistribusikan dalam wadah limbah organik. Limbah terpilah ini dapat dimanfaatkan atau didaur ulang untuk yang lain
Efforts to improve problem solving skills and critical thinking skills through problem-based integrated Computer Assisted Instruction (CAI) in Vocational Education
Full text linkBased on research conducted by PISA, the ability to solve problems and think critically of Indonesian students is still below the average score set by PISA. Problem based learning is one of the learning models recommended by the Ministry of Education and Culture to be applied in improving these abilities. However, the lack of problem-based learning that has been applied so far is the lack of use of media that can be used as support in learning activities, resulting in inconsistencies in the impact of problem-based learning in improving student skills. The importance of these skills for students to have in this era of the industrial revolution 4.0, makes educators have to be more creative and innovative in implementing learning. Therefore, this study aims at seeing efforts to improve problem solving skills and critical thinking skills through problem based integrated computer assisted instruction (CAI).

A Comparison of the Problem-Solving Skills of Students in PJBL Versus CPJBL Model: An Experimental Study
Full text linkEach learning model has different pattern and approach that will affect the learning outcomes. Thus, a study is required focused on the effect of implementing the learning model so that it can become a reference for teachers. The study aimed to compare the students’ problem-solving skills using Project Based Learning (PjBL) model and Cooperative-Project Based Learning (CPjBL) model implementation. The study was carried using out a quasi-experiment method. To reveal problem-solving skills, students used the authentic Assessment technique. A t-test was used to analyse data. The results of the study showed that there is a significant difference in students’ problem-solving skills between the PjBL and the CPjBL model, and that these differences are strongly influenced by the syntax or stages of the instructional model. Results show that CPjBL is more effective to improve students’ problem-solving skills. In PjBL model, learning activities are directed to project assignment, while in CPjBL model, learning activities of students began with motivation to achieve the learning outcomes, which were provided by modules through cooperative learning, understanding the concept and work principles through instructional media, prototype, discussion and demonstration. The cooperative learning made students group learning more structured corresponded with learning topic assigned. The students group would continue to carry out project assignment with permanent members and learning topic. The CPjBL model is more superior than PjBL model in accordance with the ability of the students as the syntax of the model is systematically organized based on learning hierarchy.

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
