Principles of lean manufacturing has been known since last two decades, however, its implementation in the local industries is a recent trend. A lot of analysis tools such as 5S, Kaizen, Kanban, flow production and line balancing have commonly been used to improve productivity by organizations across the globe as well as in the local industries.

... In business philosophy, the Lean method is based on minimizing or reducing the use of resources (including time) in various activities and focusing on identifying and eliminating activities that do not add value (non-value added activities) [1]. By adopting the tools commonly used for lean manufacturing, the tool that is applied to lean mining in gold mining companies this time is the Waste Assessment Model (WAM) [3]. This model is a waste settlement model by knowing the relationship between waste and presenting waste ratings that occur. ...
... From the results of the WRM questionnaire, the score is calculated for each question and grouping the level of interrelation between waste with the provisions: Value A = absolutely necessary (score 17-20) Value B = Especially Important (score 13-16) Value I = Important (score 9-12) Value O = Ordinary Closeness (score 5-8) Value U = Unimportant (score [1][2][3][4] The row in the WRM matrix above shows a waste that affects other waste, while the column side shows a waste that is affected by other types of waste. On the diagonal row marked with different colors, has the highest value of connection/relationship because waste that has a relationship with itself will always have the highest value of connection/relationship.

Implementation of lean manufacturing principles and believing in continuous improvement are the tools which help industries to sustain global competition. With the escalation in population, the demand for technology is increased more than ever. This leads to the steady increase in production rates of existing models and even introduction of new product models. These factors often results in “layout modification” of manufacturing industries. Plant layout improves resource utilization and provides means for application of lean tools such as 5S, seven wastes, kanban, Just In Time (JIT), etc. These tools not only contribute in reducing cost but also benefit the organization by improving product quality. This paper provides a comprehensive comparison of different approaches used in layout design. The study also simplifies the application of systematic layout planning (SLP) in the development of new layout. SLP is a technique used for layout development and material flow improvement. A case study of layout design using SLP is presented for a multinational company which manufactures a product with high variety. The results include four possible rearrangements of production departments. These layout alternatives are evaluated on basis of improved accessibility and material flow efficiency criteria. Thus, the economic benefits achieved by overall integration of facility are highlighted. The results illustrate the impact of layout design on elimination of waste and the economic benefits achieved by reducing overall material flow and lead time.
This study explains what waste occurs in the manufacturing industry, where there are 7 wastes, namely excess production, waiting time, unnecessary transportation, excessive processes, excess inventory, unnecessary movements, and defective products. As a result of this waste, the company has lost an output of 46 tons in 1 semester. The purpose of this research is to find out the critical waste and the source of the waste that occurs in the manufacturing industry and then reduce the waste using the waste assessment model and the deming cycle method. The method used to identify waste is the waste assessment model. The waste assessment model consists of 2 stages, namely the waste relationship matrix to determine the relationship between waste and a waste assessment questionnaire to identify the causes of waste. The results of this study obtained critical waste from 7 wastes, namely defect waste with a percentage of 27.94% and the cause of the waste is the frequency of machine breakdowns that occur in area 2 production. It can be concluded that the critical waste in this research is defect waste that originates from engine damage in the production area and within a quarter the waste has been eliminated so that it can maximize the production process.
The sales reduction of several companies or businesses during the COVID-19 pandemic caused they find other ways to maintain their business, as was done by McDonald's Indonesia by issuing a new BTS meal menu in collaboration with the South Korean boy group BTS. The purpose of this study was to determine the influence of brand ambassador and brand image on purchasing decisions by using case studies of Kpop and non-Kpop fans. This research used a questionnaire to obtain data on brand ambassadors, brand image, and consumer purchasing decisions, then analyzed using Confirmatory Factor Analysis (CFA) and the rotational method of varimax factor analysis. From the result, 64 respondents showed brand ambassadors influenced brand image in BTS meal purchasing decisions by 28.6%, brand ambassadors influenced BTS meal purchasing decisions by 19.4%, brand image influenced BTS meal purchasing decisions by 6.4 %, and brand image can mediate brand ambassadors to influence BTS Meal purchasing decisions. The impact of using BTS as a brand ambassador does not directly affect BTS Meal purchasing decisions but the brand image of McDonald's Indonesia can mediate the brand ambassador to influence BTS Meal purchasing decisions.
