Abstract

High 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.

Abstract

ABSTRAK                                                                        Salah satu isu penting dalam kesiapsiagaan bencana adalah pada perencanaan evakuasi yang tepat. Evakuasi menjadi faktor penting dalam mengurangi risiko bencana. Adapun pendekatan yang sering dilakukan untuk menjelaskan perilaku evakuasi adalah dengan menggunakan pendekatan simulasi. Namun dari studi literatur ditemukan masih minim pembahasan mengenai simulasi pada perilaku evakuasi bencana secara vertical maupun horizontal dan moda transportasi yang tepat. Tujuan dari penelitian ini adalah memaparkan literatur evakuasi bencana dengan pendekatan simulasi dan berbagai moda transportasi yang menjadi pilihan. Metode yang digunakan pada penelitian adalah studi literatur secara sistematis pada naskah jurnal terindeks googlescholar, Scopus, Web of Science yang dipublikasikan dari tahun 2015 sampai dengan 2021, dengan kata kunci behavioural, evacuation, simulation dan modelling. Hasil dari penelitian ini adalah berbagai pendekatan simulasi dipilih dalam mengevaluasi perilaku evakuasi karena dinilai sebagai metode pendekatan yang sesuai. Sedangkan moda transportasi yang sesuai dapat berdampak pada efektivitas evakuasi.  Adapun metode evakuasi dapat berupa evakuasi horizontal maupun vertikal.  Kata Kunci:  Bencana, Perilaku evakuasi, Simulasi, Studi Literatur  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. Keyword:  Behavioural evacuation, Catastrophe, Simulation, Literature Review

Abstract

The 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.
