Abstract

Traveling Salesman Problem (TSP) is a classic combinatorial optimization problem, one of the optimization problems that can be applied to various activities such as finding the shortest path. The optimization problem in TSP is the most widely discussed and has become the standard for testing computational algorithms. TSP is a good object to test optimization performance. With scientific developments in the field of informatics, many researchers have optimized the application of algorithms to solve the Traveling Salesman Problem (TSP). In this study, researchers used a combination of Ant Colony Tabu Search – Firefly Algorithm Tabu Search (ACTS-FATS). The combination is doneto overcome Premature Convergence (trapped local optimum) which is a shortcoming of the ant colony algorithm, get the best running time by looking at the process of each point movement with the ant colony and firefly methods. After testing, getting the best running time results of 27.79%, and getting an accuracy rate of 17%.

Abstract

Dalam proses pembelajaran keterampilan dalam menulis harus diimbangi dengan penguasaan dalam ejaan. Terutama dalam penguasaan ejaan kalimat merupakan elemen yang penting yang harus diperhatikan dalam penulisan karangan terutama pada karangan teks eksposisi. Dalam penelitian ini peneliti menggunakan metode penelitian kualitatif deskriptif untuk menggambarkan bentuk kesalahan dan daerah yang memiliki kesalahan dalam ejaan yang dianalisis pada bidang pemakaian huruf, penulisan kata, tanda baca dan pemenggalan kata. Kemudian kesalahan tersebut digolongkan berdasarkan kesalahannya. Penelitian ini dilakukan pada peserta didik kelas X SMK Al Washliyah 30 Medan. Peneliti menggunakan metode memberikan tugas kepada siswa untuk menuliskan teks eksposisi pada kertas, kemudian peneliti memeriksa hasil kerja tersebut, dan ditemukan kesalahan dalam ejaan dalam teks eksposisi. Kesalahan tersebut kemudian dikelompokkan dalam bidang kesalahan pemakaian huruf, penulisan kata,  tanda baca, dan pengolahan kata. Dari hasil penelitian ini rata-rata kesalahan yang ditemukan dalam hasil lembar kerja siswa adalah kesalahan dalam penulisan ejaan kata, hampir rata-rata ditemukan kata-kata yang tidak sesuai dengan ejaan. Melihat hal ini hendaknya pendidik memberikan pembelajaran mengenai Ejaan Bahasa Indonesia (EBI)  secara lebih baik kepada peserta didik.

Abstract

This research analyzes the application of the Multi Objective Optimization by Ratio Analysis (MOORA) method model in determining the Pilot Area at PT XYZ. This method is used to evaluate various performance criteria, including customer satisfaction, productivity, service quality, and operational efficiency. Currently, the Pilot Area assessment and selection process at PT XYZ is still done manually, which causes a lack of accuracy and efficiency. MOORA was chosen for its ability to handle multi-criteria decision-making problems more systematically and objectively. The analysis results showed that Alternative Area 7 obtained the highest final score of 0.39, placing it as an area with superior performance. The application of MOORA is proven to improve accuracy and efficiency in the Pilot Area determination process, providing a more objective basis for decision-making. By using MOORA, PT XYZ can evaluate area performance more comprehensively and accountably. This research recommends that PT XYZ implement the MOORA method thoroughly and conduct periodic evaluations of the methods used. For theory development, PT XYZ can add specific evaluation criteria according to company needs. The implementation of these suggestions is expected to improve the quality of service and competitiveness of PT XYZ in the global market. Further research is expected to compare MOORA with other methods to strengthen the validity of the results. Thus, this research not only provides a practical contribution to PT XYZ but also adds academic insight into the application of multi-criteria optimization methods in the context of performance management and service improvement.
