Galangan kapal tradisional memiliki peranan penting dalam mendukung sektor perikanan di Kabupaten Aceh Besar. Namun, proses produksi kapal kayu tradisional masih mengalami berbagai pemborosan (waste) yang menyebabkan rendahnya efisiensi waktu, tenaga kerja dan penggunaan material. Penelitian ini bertujuan untuk menganalisis tingkat efisiensi penerapan prinsip Lean Manufacturing serta mengidentifikasi jenis-jenis pemborosan utama yang sering terjadi di dalam proses produksi di Galangan Boat Yah Lim. Metode penelitian menggunakan pendekatan deskriptif kuantitatif dengan pengumpulan data melalui observasi, wawancara, kuesioner dan pengukuran waktu dengan teknik purposive sampling yang dilakukan dengan cara mengambil sampel berdasarkan tujuan penelitian. Hasil penelitian diperoleh bahwa aktivitas produksi didominasi oleh aktivitas bernilai tambah dengan total waktu VAT sebesar 321 jam, dan NVAT sebesar 120 jam . Nilai Manufacturing Cycle Effectiveness (MCE) sebesar 72,78% menunjukkan efisiensi produksi cukup baik, namun masih terdapat potensi peningkatan agar nilai mencapai 100% . jenis pemborosan paling dominan yaitu overproduction waste, transportation waste, inventory waste yang masing-masing memiliki frekuensi relatif sebesar 18,75%. Konsep penerapan prinsip lean dapat meningkatkan efisiensi dan menjadi solusi dan menimalkan pemborosan produksi, khususnya pada aktivitas yang tidak memberikan nilai tambah.

Traditional shipyards play an important role in supporting the fisheries sector in Aceh Besar Regency. However, the production process of traditional wooden ships still experiences various wastes that cause low efficiency in time, labor, and material use. This study aims to analyze the level of efficiency in implementing Lean Manufacturing principles and to identify the main types of waste that often occur in the production process at the Yah Lim Boatyard. The research method uses a quantitative descriptive approach with data collection through observation, interviews, questionnaires, and time measurement with a purposive sampling technique carried out by taking samples based on the research objectives. The results of the study showed that production activities were dominated by value-added activities with a total VAT time of 321 hours and NVAT of 120 hours. The Manufacturing Cycle Effectiveness (MCE) value of 72.78% indicates quite good production efficiency, but there is still potential for improvement to reach 100%. The most dominant types of waste are overproduction waste, transportation waste, inventory waste, each of which has a relative frequency of 18.75%. The concept of implementing lean principles can increase efficiency and be a solution and minimize production waste, especially in activities that do not provide added value.
