    Abstract
    Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA) merupakan metode pengambilan keputusan dalam proses memecahkan sebuah persoalan dengan menerapkan sistem perhitungan secara matematika yang kompleks. Proses MOORA terdiri dari pembuatan matriks keputusan, normalisasi matriks keputusan, pengoptimasian matriks dengan bobot atribut serta perangkingan alternatif terbaik. Pada beberapa penelitian terdahulu, proses pembobotan atribut diperoleh dengan cara manual (subjektif). Hal tersebut dianggap kurang tepat dikarenakan tidak ada validasi dalam pembobotan atribut sehingga mempengaruhi proses pengambilan keputusan dalam menentukan alternatif terbaik dan perolehan nilai akurasi. Maka pada penelitian ini, untuk mengatasi persoalan tersebut, penulis menggunakan Gain Ratio sebagai metode pembobotan atribut secara objektif dan sistematis dalam meningkatkan akurasi. Perhitungan akurasi menggunakan Relative Standard Deviation (RSD) dengan membandingkan hasil akurasi berdasarkan perhitungan MOORA dengan bobot subjektif dari data set dan dengan bobot dari Gain Ratio. Setelah dilakukan pengujian diperoleh hasil akurasi yaitu dengan bobot subjektif sebesar 21.44 % dan bobot Gain Ratio sebesar 33.40 %. Hasil tersebut menunjukkan bahwa Gain Ratio dapat meningkatkan akurasi dengan nilai rata-rata peningkatan akurasinya sebesar 11.96 %.
     
    Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA) is a method of decision-making in the process of solving a problem by applying complex mathematical calculation systems. The MOORA process consists of making a decision matrix, normalizing the decision matrix, optimizing the matrix with attribute weights, and ranking the best alternatives. In several previous research, the process of weighting the attributes obtained by manual (subjective). This is considered inappropriate because there is no validation in the weighting of attributes that affect the decision-making process in determining the best alternative and the acquisition of accuracy. So in this study, to overcome these problems, the author used Gain Ratio as a method of weighting attributes objectively and systematically in increasing accuracy. The accuracy calculation used Relative Standard Deviation (RSD) to compare the accuracy results based on the MOORA calculation with the subjective weight of the data set with the weight from the Gain Ratio. After testing the accuracy of the results obtained with a subjective weight of 21.44 % and with gain ratio weight of 33.40 %. Results indicated that the Gain Ratio proved can increase accuracy with an average increase in accuracy of 11.96 %.
