Abstract

The Lean Manufacturing (LM) system has been increasingly used in many industrial applications, worldwide, in the last 3 decades. The LM system is based on sound philosophy and includes several tools and principles, which permit its usage in eliminating wastes and decreasing the production costs. Though the conventional LM is helpful, the new paradigm, i.e., Industry 4.0, has started challenging the system. The traditional LM system cannot analyse the complex issues present in the existing competitive market on its own. This is because the Industry 4.0 is based on data which is more diverse, complex and fast. In this review, the researchers have attempted to identify the solution for the current scenario. Literature survey showed that simulation was a relevant tool that could be used for addressing the complexity-based issues related to the new concept. Though the combination of the simulation and LM system helped in understanding the problems, there still existed a gap in the LM system with regards to the merging of the 2 technologies of Industry 4.0.

Abstract

This study has reported the effects of different formulation ratio between recycled high density polyethylene (r-HDPE) and recycled polypropylene (r-PP) into the resulted mechanical, thermal and morphological properties of r-HDPE/r-PP polymeric blends. About five (5) different formulation ratio of r-HDPE/r-PP have been prepared and tested. The best combination ratio between r-HDPE and r-PP was determined in this work. It was found that the 70/30 wt.% of r-HDPE/r-PP blend possessed an outstanding mechanical and physical strength. About 59.80% and 2.30% of positive improvement in comparison to 0/100 wt.% of r-HDPE/r-PP was achieved for both of tensile strength and hardness, respectively. Interestingly, for 70/30 wt.% of r-HDPE/r-PP blend had also experienced major increased in their elongation at break up to 473%. The fracture morphological behavior of the tested samples that were observed via SEM observation, had established the interaction between the structure and properties of produced r-HDPE/r-PP blends, especially on the miscibility state between the r-HDPE and r-PP phases. Thermal evaluation by using the DSC had confirmed the partial miscibility state due to dominant peak shifting at 120 - 140°C and obvious melting peak reduction pattern. Overall, from this study, it was found that the blending between r-HDPE and r-PP into r-HDPE/r-PP blends are feasible to improve the properties of primary phase.

Abstract

Turnaround (TA) is a large-scale maintenance activity (extraordinary maintenance activities), which is carried out periodically (repeated large-scale maintenance), where the work referred to can only be carried out when the unit is stopped operating. The main scope of work is inspection (inspection), repair, cleaning equipment. The success or failure of turnaround activities is very influential from careful preparation, some of the failures of turnaround activities result from unplanned preparations. One factor is the readiness of the material. This paper discusses the direct involvement of the material procurement process in determining better TA preparation time. The historical data from the purchasing is analyses and then the result is combined with the new proposed procedure of the TA maintenance. The new procedure has three months less than the current procedure.

Abstract

The world is entering industry 4.0. The digital enlarges to machine maintenance known as troubleshooting. Troubleshooting is a series of actions needed to deal with machine damage treatment. Problems that often occur in troubleshooting are that technicians are not in the location, the information is still in the form of printed books, the risk of books being lost, books slipping, and the location of books far from the location of machine failure. This research was to solve this problem by developing an application called Production Machine Troubleshooting Information System (SITMEP) in relational database environment. This system was developed by integrating several methods such as machine damage knowledge obtained from tacit sourced from mechanical technicians, experts in their fields and explicit knowledge sourced from machine manual books. GT is to combine knowledge with machine hierarchies and it supports systems for database and SQL. The tool used was MS Access with VBA.
