Abstract

Transisi kendaraan listrik Electric Vehicle (EV) bertujuan mengurangi emisi CO2 di sektor transportasi. Namun, proses konversi kendaraan dari Internal Combustion Engine (ICE) ke Electric Vehicle (EV) masih menghadapi sejumlah tantangan terkait efisiensi dan kualitas proses. Penelitian ini bertujuan untuk menganalisis proses konversi kendaraan roda 2 dari ICE ke EV di Perusahaan Electric Vehicle (PEV) fokus pada identifikasi aliran proses, klasifikasi aktivitas sebagai value added, necessary but non-value added, non-value added, serta perbaikan menggunakan pendekatan lean manufacturing. Hasil penelitian menunjukkan bahwa aktivitas value-added (VA), seperti pemasangan komponen utama (baterai, BLDC motor, controller) dan inspeksi kualitas, memberikan kontribusi langsung terhadap produk akhir. Aktivitas necessary but non-value-added (NNVA), seperti transportasi dan penyimpanan, diperlukan meskipun tidak memberikan nilai tambah langsung. Sementara itu, aktivitas non-value-added (NVA), seperti waktu tunggu (waiting) dan penundaan (delay), menjadi pemborosan utama yang menghambat efisiensi. Faktor-faktor seperti waktu tunggu antar stasiun, cacat produksi (defect), rendahnya automasi, dan tata letak stasiun yang tidak optimal turut memengaruhi proses. Analisis VSM mengidentifikasi pemborosan utama berupa Defect (skor 92), Waiting (skor 73), dan Overproduction (skor 68).

===========================The transition to Electric Vehicles (EV) aims to reduce CO2 emissions in the transportation sector. However, the conversion process from Internal Combustion Engine (ICE) vehicles to Electric Vehicles (EV) still faces several challenges related to efficiency and process quality. This study aims to analyze the conversion process of two-wheeled vehicles from ICE to EV at the Electric Vehicle Company (PEV), focusing on identifying process flows, classifying activities into value-added (VA), necessary but non-value-added (NNVA), and non-value-added (NVA), as well as providing improvements using the lean manufacturing approach. The results show that value-added (VA) activities, such as the installation of key components (batteries, BLDC motors, and controllers) and quality inspections, contribute directly to the final product. Necessary but non-value-added (NNVA) activities, such as transportation and storage, are required even though they do not add direct value. Meanwhile, non-value-added (NVA) activities, such as waiting time and delays, are identified as the main sources of inefficiency. Factors such as waiting time between stations, production defects (defects) in wiring and main components, low automation, and suboptimal workstation layouts also affect the process. VSM analysis identifies the main wastes as Defects (score 92), Waiting (score 73), and Overproduction (score 68).
