Available online at https://jurnal. id/index. php/jurteksi interconnected components such as human resources, hardware, software, data, and procedures that work together to produce accurate and relevant information . In the context of used laptop sales, the large number of alternatives with relatively similar specifications often makes it difficult for customers to determine the most appropriate choice. Tech Kios Laptop Kisaran is a business engaged in selling used laptops with various brands and models. Based on sales data, differences in sales levels among brands can be observed, even when the specifications are nearly This indicates that purchasing decisions are influenced not only by price but also by other factors such as brand, laptop size, screen resolution, and battery However, the recommendation process is still conducted manually and relies on subjective judgment, which may lead to less optimal decision outcomes. A Decision Support System (DSS) is a computer-based system developed to assist decision-making by processing and analyzing relevant data and information . Research conducted by Cindy et al. shows that the combination of SAW and TOPSIS methods can generate systematic decisions in employee reward Lutfi et al. demonstrated that the SAW method is effective for weighting and ranking alternatives in selecting the best employees. Rizki . explained that the AHP method is widely used because it can systematically structure hierarchical criteria. Ilham et al. stated that the SMART method is capable of producing alternative rankings in the selection of the best teachers. The Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) method is considered a simpler and more efficient approach in the normalization and ranking process . Sawitri et al. proved that MOORA can objectively generate alternative rankings in selecting the best Syahrani and Nasution . also showed that the MOORA method can be applied in a decision support system to provide measurable and transparent recommendations for determining loyal customers. Nur and Hartatiks . MOORA can deliver accurate laptop purchase recommendations based on processor. RAM, screen size, and hard drive capacity. Although previous studies have discussed the implementation of AHP. SAW, and MOORA methods, most of them focus on employee selection, technician selection, best teacher selection, or other related fields . , . , . The application of the MOORA method in the context of electronic product selection, particularly used laptops at the scale of a local business, has not been specifically addressed in prior research. Based on the identified problems and the review of previous studies, this research aims to design and implement a Decision Support System using the MOORA method to determine the best used laptop recommendations at Tech Kios Laptop Kisaran. The proposed system is expected to generate objective alternative rankings based on predefined criteria, thereby improving consistency and service quality. METHOD This research uses a quantitative method using the Decision Support System approach. Quantitative methods JURTEKSI (Jurnal Teknologi dan Sistem Informas. ISSN 2407-1811 (Prin. Vol XII No 3.

This approach allows the analysis process to be carried out in a measurable and systematic manner so that the results obtained can be used as a basis for decision making. The data used in this research consists of alternative data and criterion Alternative data is in the form of used laptops available at Tech Kios Laptop Kisaran, while criterion data includes brand, laptop size, screen resolution, and battery life. All data are expressed in numerical values so that they can be processed using multicriteria decision-making methods. The methods used in this study were Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA). The MOORA method was chosen because it has a simple, flexible calculation process, and is able to handle In addition, the MOORA method is able to produce alternative objectively, making it easier for users to determine the best choice . The initial stages of the MOORA method are . First, determining a decision matrix, which is a matrix containing the values of each laptop alternative against each of the predetermined criteria. The decision matrix can be written as follows: The decision matrix represents the initial data containing the performance values of each alternative against all predetermined criteria. Second, determine the normalization matrix. The decision matrix is then normalized to eliminate scale differences between criteria. The normalization process is carried out using the following ocm Explanation of Symbols: x'A = Normalized value of alternative i on criterion j xA = Original value of alternative i on m = Total number of alternatives Oc = Summation symbol xAA = Squared value of alternative i on Oo = Square root symbol Normalization is performed to eliminate scale differences among criteria so that all values become comparable. Third, normalization matrix. Once a normalized matrix is obtained, the next step is to calculate the optimization value for each The optimization value is obtained by adding the value of the criterion that is advantageous . and reduce the value of cost criteria . , as shown in the following .
