<![CDATA[This study offers the practical part of our academic, conceptual paper on the ICEBERG Problem Solving Tool (IPST) within the application of a case study for an authorized automobile dealer in Riyadh, Saudi Arabia. The research is designed to represent how to operationalize the ICEBERG model practically in business problem-solving by using the concept of the IPST. The research is a qualitative case study within action research. It is a three cycles of action research. The tool application identified five levels of analysis besides the cross-functional analysis, the root cause of the persistent operational events and clearly showed the leverage points in the whole sales retail system. The “IPST” five levels of analysis enable us to see the complete picture of the cause of the events, touching the leverage points for decision-makers or the organizers. It is a quick fix for pining issues of repeated business events for the dealer's high performance. With theoretical roots in system thinking, this paper contributes to applying the ICEBERG model through “IPST” as a practical problem-solving tool for the business complex environment, has puzzles (operational killing events) around the whole business process and needs to be solved for a better performance.]]>

<![CDATA[The traditional shipbuilding industry is crucial in the global maritime sector, contributing to ship construction, repair, and maintenance. However, it faces challenges in improving production process efficiency. This article explores strategies to optimize the industry's manufacturing cycle. A comprehensive literature review identified key challenges, including production planning errors, coordination issues, material delivery delays, and limited technology integration. These challenges result in higher costs, reduced productivity, and project delays. To address these issues, the article proposes integrating efficient management systems like Lean Manufacturing and Total Quality Management to enhance the production cycle's efficiency. Implementing these systems eliminates non-value-added activities, simplifies processes, and reduces wait times. Additionally, the Manufacturing Cycle Efficiency method is valuable for analyzing production processes, identifying waste, bottlenecks, and interruptions, and optimizing workflows. In conclusion, this article provides insights and strategies to optimize the traditional shipbuilding industry. By integrating efficient management systems, utilizing the MCE method, and embracing sustainability practices, shipyards can enhance production cycle efficiency, increase productivity, and gain a competitive advantage, supporting industry growth and paving the way for a sustainable future.]]>

<![CDATA[A company is a group of people who are members of an organization who work to achieve certain goals. One of the most basic company goals is to obtain maximum profit or profit from the company's business activities. The purpose of establishing a company is not only to achieve maximum profit, but also aims to increase the prosperity of parties related to the company's business activities, such as shareholders and stakeholders so that the value of the company increases. The research method used is a quantitative data method. Working capital management has a positive and significant effect on firm value, leverage has no significant effect on firm value, and working capital management and leverage have no simultaneous significant effect on firm value. Company value can be used as the basis for making investment decisions because this aspect measures the ability of the company's assets to generate a return on investment made in the company's asset instruments. This study concludes that manufacturing companies listed on the Indonesia Stock Exchange will always maintain the value of the company, and this research should be a strategy or consideration for Manufacturing companies pay attention to company values in carrying out company activities. Paying attention to working capital management, leverage, profitability and especially firm value because this aspect is very attractive to investors in conducting technical analysis and predicting the movement of the company's stock price. It is interesting if the company has a good corporate value. So that investors can find out risk analysis and predict the value of the company, of course investors will be interested in investing their funds in the company.]]>

<![CDATA[The industrialization of marine and fisheries is the integration of production systems from upstream and downstream, to increase the scale and quality of production, productivity, competitiveness, and value added of fishery products. Bio-ecoregion-based fisheries and marine resources from each region, especially in West Java, which is one of the producers of fisheries and marine production through the development of industrialization innovations 4.0. This study aims to analyze how to promote 4.0 industrial innovations for Fisheries Bioecoregion, case study in West Java Province, Indonesia. The method used in this research is quantitative description, using primary and secondary data. Data analysis tools use SWOT to systematically analyze various factors based on logic that can maximize strengths and opportunities, but simultaneously can minimize weaknesses and threats. Based on the research results, the strength that is owned is to create a transformation of the potential of fishery resources to the exploitation of fishery resources based on Bioecoregion. Opportunities faced by the transformation of open market access management and high competitiveness in fisheries and marine products. The challenges faced must be able to create a digital bio-ecoregion-based fishing industry system. The threat faced by the transformation of the workforce towards digitalization. Based on the SWOT analysis being in quadrant 2 it means it is in a diversification strategy. Promoting 4.0 Industrial Innovations For a Fisheries Bioecoregion, based on: increasing the added value of fisheries industrialization, increasing the competitiveness of fishery products; strengthening of marine and fisheries industry players; commodity-based, regional, and regional management systems with a concentration on leading commodities, modernization of upstream and downstream production systems; balance between the use of natural resources and sustainable environmental protection; and changes in the mindset and behavior of modern society.]]>

<![CDATA[Selecting and weighting the companies are the main processes in portfolio optimization. It is important to select and determine the companies' weights in constructing the optimal portfolio. In this paper, we propose a two-phase Mean-Absolute Deviation (MAD) model in portfolio optimization of technology companies in Malaysia. In the first phase, the companies’ financial performance is determined and ranked with Fuzzy Technique for Order of Preference by Similarity to the Ideal Solution (TOPSIS). Selection of the good financial performance companies can minimize the influence of firm-specific risk in minimizing the risk of the portfolio at the expected return. In the second phase, the optimal portfolio is generated by weighting the selected companies with MAD model. The results indicate that the investors can minimize the portfolio risk to achieve the expected return with the two-phase MAD model. The significance of this paper is to contribute to the development of portfolio optimization by integrating the Fuzzy TOPSIS and MAD approaches.]]>
