Abstract

The Fuzzy Multi-Attribute Decision Making (FMADM) method is an approach to find the best choice from a number of alternatives according to predetermined criteria. In FMADM, there is a technique called Fuzzy Weighted Product (FWP), which uses the concept of ranking by multiplying the value of the criterion by its weight. The weight of the criterion is calculated by multiplying the value by the weight of the criterion. This study aims to apply FWP in assessing the poverty level in an area, where poverty reflects the unmet economic needs of the community according to the average standard of living of the region. One proposed solution is to use the FWP method. This process begins by setting goals, alternative decisions, and criteria that will be used to determine poor areas in West Sumatra Province. The steps to implement FWP include the determination of criteria and their weights, the assessment of alternative preferences (S), and the evaluation of relative preferences (V). The best decision is determined based on the highest relative preference value, which is expected to support decision making in poverty-stricken districts in West Sumatra Province.

Abstract

The Fuzzy Simple Additive Weighting (FSAW) method is a mechanism that can be used to support decision making. This method was chosen because a ranking process was carried out to determine the weight value of each attribute, which would select employees who were worthy of occupying the promoted position. This study aims to determine the results of the application of the FSAW method in the assessment of civil servant promotion at the Malang City Education and Culture Office to increase objectivity and fairness in the assessment of employee promotion. Some problems that often occur in employee evaluation are the employee evaluation process which is still conventional so that it is less effective in calculation. The solution to overcome this problem is to use a Fuzzy Multi Attribute Decision Making (FMADM) decision support system with the FSAW method. This method requires a process to normalize the decision matrix (X) against a scale that can be compared with all available alternative values.  After each attribute has been determined its weight value, the ranking process is used to select the best alternative for this study.  The criteria used in this decision support system are SKP score, length of service, class, and education. The membership function used is the Triangular Fuzzy Number (TFN) representation. The results of the ranking calculation or the best value show the highest value, namely 1 from alternative 1 (employee 1) who is entitled to a promotion. It is expected that by using the FSAW method, the task of selectors will be able to more quickly and precisely identify employees who are worthy of occupying positions promoted based on the desired conditions.

Abstract

Distribution is the action or process of supplying goods to stores and other businesses that sell to consumers. If a product or service is distributed from a company, it requires adequate means of transportation and usually requires too large distribution costs. Delivery of goods at this company does not use mathematical methods in calculating its distribution to several places correctly. The purpose of this research is to create an optimal, efficient and effective distribution model for this company by applying the North West Corner Method and the Modified Distribution Method in July, August and September 2021. North West Corner Method for the initial solution and Modified Distribution Method as the optimal solution is a variation of the Stepping Stone method. The results of this research show that the distribution costs incurred by the company after being calculated using the North West Corner Method and the Modified Distribution Method are Rp. 6,961,779, - from Rp. 7,000,000. Then these two methods are able to help companies save distribution costs incurred.

Abstract

PT Citra Akes Indonusa is a company that operates on the expertise of information technology services in Banten Province. One of the services provided by the company requires the construction of a Base Transceiver Station (BTS) tower. The tower requires maintenance if there is damage to the network signal. As a result, the shortest route is needed to make it easier for employees to reach the tower location to be more effective. There are eight BTS tower locations in Tangerang Regency and three BTS tower locations in Tangerang City. The process of finding the shortest route in this study uses the Floyd Warshall algorithm, which is unique in finding the shortest route by comparing each edge of all edges that are passed. The process of testing the shortest route is done by selecting the starting point, then selecting several BTS tower locations. Next, the shortest route will be searched using the Floyd Warshall algorithm from each point of destination for the BTS tower location, then the BTS tower location will be selected first and so on until the last destination. The effectiveness of this shortest route search involves a comparison of the routes presented by Google Maps. Based on the results of 30 randomized trials on BTS tower locations, the average shortest route effectiveness was 25.54% compared to the route generated by Google Maps. This is due to the selection at each BTS tower destination location so as to make the route more effective.

Abstract

K-Algebra is constructed on a group using binary operations ⊙ on (G,*), so for each x,y∈G defined as x⊙y=x*y^(-1)=xy^(-1) with certain axioms on K-Algebra. K-Group summation is defined as the elements of K that operate summation in K, similar to addition in K itself. Meanwhile, the K-Ring has two basic operations, namely addition and multiplication, both of which must satisfy certain properties and use the K-Field as a scalar field. Finally, the K-Field is described as a special K-Algebra structure in which the multiplication operation is distributive to the addition operation. This research contributes to a deeper understanding of structures and operations in K-Algebra. The next research is that K-Algebra can be applied in sets meaning that it can be applied to sets of numbers, dihedral, and modulo or congruence, which are equipped with theorems, proofs, and examples.

Abstract

Analytical Hierarchy Process (AHP) is a method in decision making by analyzing multi-attribute decisions with many criteria and alternatives. these weaknesses, then the incorporation of fuzzy concepts is carried out, because there is a range of values that can cover the uncertainty of decision making in AHP. The merger of the two concepts is known as Analytical Hierarchy Process-Fuzzy or AHP-Fuzzy. The AHP-Fuzzy method uses an extended analysis with a triangular fuzzy membership function or TFN. Meanwhile, there is data on narcotics and psychotropic crimes. The data contains the indictment of each defendant containing the articles violated, prison sentences, and fines. Because it fulfills the AHP-Fuzzy method by having the main criteria. The author takes the formulation of the problem, namely the AHP-Fuzzy method to determine the priority level of criminal acts of narcotics and psychotropic abuse. This research aims to find out how the role of the AHP-Fuzzy method in criminal case data. The adjustment of the method when processing criminal offense data, producing the final result is at the stage of determining the crisp value and weighting. Before entering the crisp value determination stage, first determine the variables and the range of values that adjust the data conditions. Then, the weighting stage contains the results of the multiplication between AHP priority weights and weight vectors in fuzzy concepts. Thus, each of the main criteria has a different percentage priority level. The highest priority level is article 114, followed by article 112, article 111, and article 127. This priority level information can be used as a reference in preventing the spread of narcotics and psychotropic drugs, especially in Malang City.
