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. Keywords: Decision Making, MCDM, UAV, and DEMATEL

Abstract

The bow of the ship is an important part in the design of the ship, as is the bow of the KCR-60, because it is the part that experiences the greatest pressure, stress from the crashing waves, with the Axe Bow bow design which has a bow profile like an axe, the slender shape of the waterline is able to reduce impacts. waves, increase the efficiency of the inflow rate, reduce the resistance the ship receives, resulting in better speed. This research changes the Conventional Bow KCR-60 design into the Axe Bow design concept and calculates the total resistance of the Axe Bow design numerically using the Holtrop method and carries out comparative analysis using the MARIN DESPPC 1999 computing program and Maxsurf Resistance V8i software. The results of this research show that the total resistance value of the KCR-60 Axe Bow bow type at a speed of 28 Knots is 364.2 kN and the Conventional Bow type is 374.5 kN, a difference of 10.3 kN which is 2.75% smaller than the Conventional Bow type in the analysis. Maxsurf Resistance V8i software comparison. For comparative analysis of the 1999 MARIN DESPPC program, the total resistance value of the KCR-60 Axe Bow concept at a speed of 28 Knots is 283.6 kN and the Conventional Bow type is 288.1 kN, the difference is 4.5 kN, 1.56% smaller than the Conventional type Bow. Keywords: KCR-60, Axe Bow, MARIN DESPPC 1999, Holtrop.

Abstract

The demand for halal cosmetic products in various parts of the world has increased, especially in Muslim-majority countries like Indonesia. The potential demand for halal cosmetic products will continue to increase in the future. Indonesia has the opportunity to become the world’s largest producer and consumer of halal cosmetic products. Therefore, Indonesia must be able to take advantage of these opportunities by maximizing its potential. This study aims to determine the effect of knowledge, religiosity, attitudes, and Islamic advertising factors on the purchase intention of local halal cosmetic products. In addition, it also aims to find out the reasons for the purchase intention of Muslim consumers towards local halal cosmetic products and to determine the purchase intentions of Muslim consumers towards imported cosmetic products in the future. This study used 400 respondents who are Muslim and domiciled in West Java. Then to test the model and hypothesis using Smart PLS Software. The results of this study indicate that all hypotheses are accepted. Knowledge and religiosity have a positive and significant influence on attitudes and purchase intentions. Then attitude and Islamic advertising have a positive and significant influence on the purchase intention of local halal cosmetic products. Thus, in building the intention to buy local halal cosmetic products, the company must know and understand what factors underlie consumers’ intentions to buy local halal cosmetic products.
