Abstract

PT. XYZ is a company engaged in the furniture manufacturing, one of which is sofa. PT. XYZ as a large company has a vision towards waste elimination and the application of lean tools to improve effectiveness and efficiency in its supply chain.  This vision is difficult to realise due to the lack of socialization, inavailability of company skills/expertise, and the absence of guidance for employees in implementing the lean SCM concept. The purpose of this study is to identify the formulation of stages in change management using the Change Acceleration Process (CAP) model. The spaghetti diagram approach is carried out to measure the distance between materials/materials and workers and an analysis is carried out to improve the layout of the work station to reduce the movement distance. Improvements to the layout of the work station using the Activity Relationship Chart and continued with the Activity Relationship Diagram. From the results of the improvement in the layout of the work station, the initial displacement distance of 174m was shortened to be only 116.4m.Keywords - Lean SCM, Change Acceleration Process, Spaghetti Diagram, Activity Relationship Chart, Activity Relationship Diagram

Abstract

The decline in the performance of the food and beverage sector by -3% for the food sector and -26.39% for the beverage sector in the second quarter of 2020 due to the outbreak of Covid-19 necessitated an analysis of the sustainability of the food and beverage industry. This research aimed to analyze the sustainability of the industry. A monitoring system for the sustainability of the food and beverage industry was an essential tool to ensure that the sector operated sustainably and contributed positively to the environment and society. Multidimensional Scaling (MDS) could be used to analyze and visualize the sustainability performance of the food and beverage industry based on various relevant dimensions or factors. The simulation results of Rapid Assessment of Food and Beverages (RAP-FB) indicated an overall high level of sustainability at 64.89%. In summary, the research showed that the food and beverage (F&B) industry's sustainability could be assessed through various dimensions and factors (such as Gross Domestic Product (GDP), energy efficiency, and workplace safety) contributed significantly to its overall sustainability. The monitoring system based on MDS could provide valuable insights to enhance the industry's performance and ensure its continued positive impact on the environment and society.

Abstract

This study explores the relationship between business strategy, business performance, innovation, and competitive advantage and their impact on customer value for non-apparel textile SMEs in Indonesia. Using Structure Equational Modeling (SEM), it aims to understand how business strategy affects business performance and innovation and how business performance and innovation mediate the relationship between business strategy and competitive advantage. In addition, it investigates the role of competitive advantage as a mediator in increasing customer value.The results show that business strategy has a significant impact on business performance, innovation, and competitive advantage. Competitive advantage proved to be an important mediator in improving customer value. However, business performance and innovation are not always effective in mediating the relationship between business strategy and competitive advantage or customer value. The findings indicate that while business performance and innovation are important, they should be viewed as part of a more holistic approach to business strategy.This research concludes that companies should focus on strategies that integrate competitive advantage through various elements, such as innovation, product quality, and marketing. Good strategic planning and effective implementation are key to achieving and maintaining competitive advantage and increasing customer value. The findings provide important insights into the need for a holistic strategic approach to achieve long-term success in an increasingly competitive market.

Abstract

The use of coal as the primary raw material for Steam Power Plants (PLTU) poses serious challenges related to sustainability, particularly due to high emissions, pollution risks, and supply chain dependence on non-renewable energy sources. Partial coal substitution with biomass is considered an effective strategy to reduce environmental impacts while supporting new and renewable energy targets. This study aims to analyze the potential of palm oil solid waste, wood pellets, and charcoal briquettes as coal substitutes using the Soft System Methodology (SSM) approach. The study follows seven SSM stages, starting from problem identification, compiling a problem description, formulating a root definition, CATWOE analysis, building a conceptual model, a debating process, and recommending corrective actions. The analysis results indicate that biomass substitution is feasible if supported by an integrated logistics system, the availability of biomass supplies, and compliance with the technical specifications for PLTU combustion. Biomass from palm oil waste, wood waste, and agricultural residues has a fairly stable energy value and can be obtained through a more environmentally friendly supply chain. Overall, this study confirms that the SSM approach is effective in understanding the complexity of coal-fired power plant problems and formulating renewable energy-based solutions through strengthening the biomass logistics system.Keywords - Biomass, PLTU, Renewable Energy, Soft Systems Methodology, Supply Chain Logistics.
