ABSTRACT
Readiness in catastrophe is the one of critical issues in evacuation planning. The evacuation becomes success factor in reducing the number of victims. The simulation is frequently applied to interpret behavioural evacuation and to evaluate the evacuation effectiveness. Nevertheless, only few literatures discuss about how simulation approach in behavioural vertical or horizontal evacuation, and transportation mode. The objective of this paper is to review literature that discuss about simulation approach in behavioural evacuation and also choosing the transportation modes. Systematic literature review is applied method and it is done for manuscripts published in 2015-2021 indexed by Google scholar, Scopus, and Web of Science. The key words are behavioural, evacuation, simulation and modelling. The result is simulation approach is appropriate method for analysing behavioural evacuation in various natural disasters. Furthermore, the choosing of transportation modes might effect on evacuation effectiveness. And also there are two evacuation methods; horizontal and vertical evacuation.

No full textThe problem that occurs in the production of sintered ore is the number of defective products. In this study it was conducted with the aim of knowing the factors that cause the product to become broken, understanding the processes that most often appear following the elements and providing proposed improvements to improve product quality and reduce them using the method of failure mode and effect analysis and seven tools. Based on the results of the highest Risk Priority Number (RPN) is the proportioning process with a score (252), Sintering with a score (168), Drum Mixing 2 with a score of 126, drum mixing 1 with a dozen (90), sintered cooling with a rating (45), and a sinter crusher with a score (18). The priority for repairs is the proportioning process
Perbaikan Waktu Set Up dengan Metode Single Minute Excange of Dies pada Mesin Die Casting
No full textThe time needed to set up the production machine is 55 minutes. The high set-up time is caused by the non-differentiation of internal set-up and external set-up so that all set-up activities are carried out when the engine stops (internal set up). When viewed from the effectiveness of the company, the setup activities carried out at the time of the engine stop will significantly harm the company, which in turn will have an impact on the high bottleneck which results in delays in the production process in specific capacities. Research activities are carried out by direct measurement of die casting machines using a stopwatch. In this study, the authors conducted a study to apply the SMED method when setting up die casting machines at PT Mitsuba Indonesia. The SMED (Single Minute of Exchange Die) method as an approach is considered as one of the solutions used to reduce the setup time of the machine. From the results of the study, it was found that the set-up time was 35 minutes, or efficient by 64% on the set-up time before the repair
mplementation of lean manufacturing to enhance the efficiency of acrylic resins production process
Get PDFHigh lead time processing of acrylic resins leads to the production of products to consumer undergoes and high-production costs. This study aims to reduce lead time by analyzing various activities that have value-added, non-value-added, and necessary non-value-added. The research is conducted using lean manufacturing approaches on acrylic resin production processes. The analysis shows that the activity of delay and transportation is a contributor of waste that occurs in the production process of acrylic resins. Improvements by minimizing both activities in the are thining tank, reactor, and monomer tank can increase the efficiency of the production process. The improvement results show a decrease in lead time from 1298 minutes to 1075 minutes. This study demonstrates that lean manufacturing can improve the time process efficiency of 17.18%, which means the output ratio will increase by around 17.18% in a process.High lead time processing of acrylic resins leads to the production of products to consumer undergoes and high-production costs.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
