Abstract

Perkembangan metode komputasi telah mengalami percepatan yang luar biasa. Berbagai teknik komputasi untuk mendapatkan solusi dengan kinerja optimal terus berkembang. Sejumlah algoritma termasuk dalam rumpun Evolutionary Computation, diantaranya adalah Differential Evolution (DE) yang berhasil menyelesaikan masalah optimasi dalam berbagai bidang diantaranya masalah clustering. Keunggulan DE adalah karena implementasinya yangmudah dan kecepatan konvergensinya. Dalam clustering, DE menghadapi kendala penentuan jumlah cluster. Pada penelitian ini diimplementasikan sebuah algoritma Evolutionary Clustering (EC) yang merupakan pengembangan dari DE. EC diterapkan untuk melakukan pengelompokan pixel-pixel dari citra gray-scale atas beberapa area homogen yang berbeda satu dengan lainnya. EC tidak membutuhkan informasi awal tentang jumlah cluster yang akan terbentuk. EC menjadi salah satu solusi untuk menentukan jumlah cluster optimal dengan nilai validitas yang lebih baik. Kinerja dari EC akan dibandingkan dengan algoritma Fuzzy C-Means (FCM). Hasil dari EC dibanding FCM relatif sama dari segi nilai cluster validity index namun EC membutuhkan waktu relatif lebih singkat.

Abstract

Background: This study addresses the broader issue of enhancing the economic impact and sustainability of community vocational training centers (BLKK). It focuses on the BLKK programs in East Java, West Nusa Tenggara, and East Nusa Tenggara, with the purpose of evaluating their potential to evolve beyond training facilities into effective business incubators that foster community entrepreneurship. Purpose of the Study: The purpose is to assess the capacity of BLKK centers to function as business incubators. The objectives are to identify the critical factors—such as human resources, leadership, environment, and collaboration—necessary for this transition and to provide actionable recommendations for improvement. Methods: The study employs a mixed-methods approach, utilizing field visits and questionnaires to collect empirical data from the targeted BLKK centers. The analysis is framed within a holistic perspective that considers integrated organizational and ecosystem development. Results: The findings underscore that transforming BLKK centers into effective incubators requires a comprehensive strategy. Key recommendations include aligning training curricula with market demands, improving tenants' access to capital, expanding professional and business networks, and instituting robust post-incubation support mechanisms. The study concludes that continuous monitoring and evaluation, coupled with these strategic enhancements, are vital for developing a competent workforce and promoting sustainable business practices within the community.
