Abstract

Decision-making is the process of selecting from several alternatives. Decision-making in selecting an alternative is a series of long processes, starting with identifying problems, seeking information about the alternatives to be selected, and analyzing how good each alternative is, leading to alternative decisions to be made. At the stage of identifying the criteria of an alternative, it is not only about identifying these criteria but also knowing the interrelationships between the criteria of the alternative to be selected. The DEMATEL method is one of the methods in multi-criteria decision-making that can be used to identify the interrelationships between criteria. In this study, calculations were carried out using the DEMATEL method to identify twenty criteria used in the selection of unmanned aircraft. From the results of this study, the DEMATEL method was able to identify and describe the relationship between the criteria quantitatively in the form of a table of the number of relationships and an impact-digraph map. The results of this study indicate that of the twenty criteria, four of the most influential criteria were obtained in the decision-making process for selecting an unmanned aircraft, with the payload criteria being the most influential criterion with the largest value of 0.412, followed by the political criteria in second place with a value of 0.356, while the endurance criteria and range are in third and fourth place on the four criteria that most influence the decision-making process for selecting an unmanned aircraft with a value of 0.355 and 0.341, respectively.

Abstract

Aim: This research aims to use the Analytical Hierarchy Process (AHP) technique, a form of multi-criteria decision-making, to rank the relative merits of potential courses of action. Through pairwise comparisons based on importance levels, AHP unites different individuals’ qualitative, subjective evaluations into a collective evaluation of decision-making.Method: In this study, we will draw from existing literature on water resource management and planning to establish our criteria and sub-criteria. Experts in a dam, reservoir, and water resource management use FGD to finalize criteria/sub-criteria because of a knowledge gap between the two sets of studies. After collecting data from the FGDs, the criteria and sub-criteria are used in an AHP to rank a set of potential solutions.Findings: The following is the outcome of applying weights to the pairwise comparisons we conducted using the criteria of social, environmental, technical, and economic aspects: With 36.2% of the vote, the option of raising the dam body by 5 meters is deemed most important. In terms of alternatives, a 0.5-meter-higher spillway comes in second with a weight of 25.7%, while dredging sediments to the same depth as sediment inflow comes in third with a weight of 20.5%, and maintaining the current configuration receives the least amount of weight at 17.7%.Implications/Novel Contribution: All stakeholders must back and contribute to the development of research aimed at extending the useful life of existing reservoirs. It is common knowledge that all reservoirs have a finite amount of time before they must be shut down. Old, inefficient reservoirs are expensive to keep up and close. However, a new dam will not come cheap, and finding a suitable site is uncertain.

Abstract

This research goals to know the impact of the psychological contract on Innovative Work Behavior, and how the role of work engagement moderates this relationship. The population at PT XYZ is 110 workers. Sampling was taken using the simple random sampling method. This study uses a statistical method called Partial Last Square to analyze the influence and moderation of Innovative Work Behavior. The study findings are that the Psychological Contract in the Relational Contract and Transactional Contract Dimensions has a significant impact on Innovative Work Behavior. Work Engagement is able to significantly moderate the relationship between the Psychological Contract on the Relational and Transactional Contract Dimensions on Innovative Work Behavior. This study aims to enrich the existing literature on psychological contracts, innovative work behavior, and work engagement. The primary objective is to explore the intricate relationships between these constructs and how they collectively influence organizational outcomes. By delving into these relationships, the research seeks to provide valuable insights and practical recommendations for human resource management practices.

Abstract

The industrial sector is a major contributor to carbon emissions, driving the greenhouse effect and global warming. Pupuk Iskandar Muda (PIM) Company, as a petrochemical company, is committed to reducing carbon emissions through enhanced energy efficiency and low-emission technology adoption, although its carbon emissions remain high and have significantly increased. This study aims to identify internal and external factors influencing PIM's Company carbon emission reduction strategy and to determine the optimal priority strategy. The research uses a quantitative descriptive method. The respondents are employees of Pupuk Iskandar Muda Company, selected using the purposive sampling technique, resulting in a sample size of 11 people. The research data includes primary data obtained from observations, interviews, and questionnaires, while secondary data is gathered from supporting literature. Data analysis techniques include SWOT analysis, Analytical Hierarchy Process (AHP), and post-risk-based strategy. The research results identified 12 alternative strategies, with two prioritized alternatives selected as the best options based on a post-risk internal strategy analysis, incorporating financial mitigation considerations. These prioritized strategies are: "enhancing an intensive marketing relationship program and increasing employees' understanding of the importance of sustainable practices to achieve emission reduction targets (CBA 4.54); Replacing part of the factory equipment in accordance with company policies to reduce carbon emissions while contributing to national food and energy security (CBA 2.24).
