Abstract

Effective and data-driven decision-making has become an urgent need for local governments in facing the challenges of public service complexity, socio-economic dynamics, and demands for transparency and accountability. One of the strategic approaches to support this process is through the implementation of a Knowledge Management System (KMS). This research aims to explore the role and impact of KMS implementation on the improvement of decision-making quality in regional government organizations. A qualitative approach is used in this study with a case study method on several regional government agencies in Indonesia that have implemented KMS, combined with an analysis of related academic literature. Research results show that KMS is capable of improving the efficiency of storage, distribution, and access to organizational knowledge, both tacit and explicit. KMS supports faster, more accurate, and participatory decision-making because strategic information can be obtained and used promptly by policymakers. The findings also indicate that the success of KMS implementation is greatly influenced by organizational culture, leadership support, and the capacity of human resources in managing and sharing knowledge. This study recommends the comprehensive integration of KMS into the government work system, with an emphasis on training aspects, digital infrastructure, and internal policies that support the knowledge-sharing process. The theoretical and practical implications of these findings are an important contribution to the development of knowledge-based governance at the regional level.

To produce graduates who have potential, reliability and competence in the field of technology and information, it is necessary to make a selection at the beginning, namely at the time of admission of new students. There are 5 criteria used in the selection process, including the average report card score, basic ability test, computer ability test, psychological test, and interview. Each criterion has 5 weights of values, namely very high, high, medium, low and very low.  The selection process for admission of new informatics engineering students with a decision support system for the EDAS (Evaluation Based On Distance From Average Solution) method.  Where the stages in this method are by normalizing the decision matrix and looking for the average from alternatives, then from these results calculate the average positive distance (PDA) and negative distance (NDA) as well as the assessment of the weighted attribute weights of SPi and SNi, after that the normalization of positive and negative distance weights is carried out for determining the ranking score. From the results of the analysis carried out using the EDAS method, with a sample of 10 prospective students it was concluded that the 6th order student candidate had the highest score with a score of 0.519 and the lowest score in the 7th order student with a score of 0.14. Therefore, the level of accuracy of the EDAS method in selecting new student admissions is around 20%. Of course, this accuracy value will change with large data samples.

Abstract

Open Shortest Path First (OSPF) merupakan salah satu protokol routing dinamis yang paling umum digunakan dalam jaringan komputer. Salah satu fitur penting dalam OSPF adalah Equal Cost Multipath (ECMP), yang memungkinkan penggunaan beberapa jalur dengan biaya (cost) yang sama untuk mendistribusikan lalu lintas jaringan secara seimbang. Namun, perubahan cost yang terjadi pada jalur tersebut dapat memengaruhi kinerja routing, terutama ketika terjadi kondisi asymmetric path. Penelitian ini bertujuan untuk menganalisis pengaruh perubahan cost terhadap proses routing pada ECMP dan asymmetric path dalam OSPF. Metodologi yang digunakan meliputi simulasi jaringan menggunakan perangkat lunak simulasi untuk mengukur performa jaringan berdasarkan metrik-metrik seperti throughput, latency, dan packet loss dalam berbagai skenario perubahan cost. Hasil penelitian menunjukkan bahwa perubahan cost yang tidak seimbang pada jalur ECMP dapat menyebabkan ketidakseimbangan lalu lintas, peningkatan latency, dan penurunan throughput. Selain itu, kondisi asymmetric path juga menunjukkan adanya degradasi kinerja yang signifikan dibandingkan dengan kondisi jalur simetris. Temuan ini memberikan wawasan yang lebih mendalam tentang bagaimana parameter cost dalam OSPF memengaruhi kinerja routing, serta memberikan rekomendasi untuk pengelolaan cost yang optimal guna memastikan distribusi lalu lintas yang efisien di jaringan yang menggunakan OSPF.
