Penerapan Metode Single Minute Exchange of Dies (SMED) untuk Mempercepat Proses Dandori Pada Mesin Robodrill di Perusahaan Komponen Otomotif
No full textPerusahaan manufaktur otomotif memproduksi berbagai model komponen otomotif dengan tingkat kesulitan produksi yang tinggi, menyebabkan adanya waktu dandori atau waktu setup proses pergantian part dan pergantian tools pada part C81 di mesin Robodrill line PD4 mencapai total rata-rata 2.139.000 detik selama periode Juli hingga Desember 2022. Oleh karena itu, perlu dilakukan pengurangan waktu tersebut untuk dijadikan standar perusahaan. Langkah perbaikan waktu dandori di mesin Robodrill dilakukan menggunakan metode Single-Minute Exchanged of Dies (SMED) dengan siklus PDCA 8 langkah dan basic 7 tools. Setelah dilakukan analisis akar masalah, ditemukan penyebabnya berasal dari faktor machine, methode, dan environment. Perbaikan pada faktor machine melibatkan pembuatan stopper dengan desain sistem plug & play yang mempermudah proses pergantian stopper dan mengubah cara pengukuran tool (zero sett, Z Axis), pada faktor method ditambahkan sistem program makro pada menu tool offset, dan faktor environment dibuat alat penggantian tool di area mesin Robodrill 3 line PD4. Hasil yang didapat setelah perbaikan adalah penurunan waktu dandori pergantian part dan pergantian tool dari sebelumnya 850 detik menjadi 478 detik, dengan persentase efisiensi waktu sebesar 44%. Dan penghematan biaya sebesar Rp 6.585.600 per tahun dengan ROI selama 0,4 tahun atau 5,2 bulan
Value addition with Blue Ocean Strategy Approach at SMI Cosmetics of Indonesian PT Company
No full textPT. Budi Andhika Prima Ayudia is an industry engaged in cosmetics, the problem that will be discussed in this research is to increase product value with the aim of expanding market share, this problem was raised based on initial discussions with partners. The method that will be used is the blue ocean strategy approach. The blue ocean strategy has a 4-step framework consisting of eliminating, reducing, raising, and creating steps. This strategy is a business strategy that implements strategies by controlling market share that is not contested. This strategic approach is expected to provide alternative solutions and ideas to maintain the sustainability of this industry, and the industry can gradually implement the strategies formulated by researchers
Quality Improvement on Optical Fiber Coloring Process using Fault Tree Analysis and Failure Mode and Effect Analysis
No full text
This study aims to identify the types and causes of defect, and also provide recommendations for improvements to reduce and prevent defect in the optical fiber coloring process. The fault Tree Analysis (FTA) Method is used in this study to identify the relationship between the causative factors and the shape of the fault tree. The Failure Mode and Effect Analysis (FMEA) method is used to analyze the causal factors identified by the FTA method. The results of the FTA Method show that the dominant defect type that occurs in the optical fiber coloring process is stripped fiber. The percentage of striped fiber defects is 36% which caused by machine, material, and method factors. The final result of the Failure Mode and Effect Analysis (FMEA) method is the highest Risk Priority Number (RPN) value, namely clogged ink housings (dies) with an RPN value of 294
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
