Abstract

Currently, almost every household in Indonesia has a motorbike, this is certainly a business opportunity. One of the most important components of a motorbike is the tire which functions to reduce vibration and protect the wheel from wear and damage. The business environment operating in the automotive sector needs to create high-quality goods or services to increase customer satisfaction. Costs in the company's productive processes must be reduced to achieve effectiveness. The object of this research is the XYZ Tire Workshop located in East Jakarta. In a day, the XYZ Ban workshop can provide up to 25 to 30 motorbike tire changes. Meanwhile, the workforce on duty is only 2 mechanics and the quantity of tools is limited. This causes delays and makes customers have to wait quite a long time before their motorbike can be worked on. The Single Minute Exchange of Dies (SMED) method which is included in lean tools is the key to reducing set-up process time. In general, SMED aims to standardize and simplify operating processes. The SMED technique is used as an element in Total Productivity Maintenance (TPM) in various studies to achieve lean manufacturing. Based on research data, the set-up time before implementing SMED was 177 seconds. After implementing the SMED method, the setup time was 126 seconds. This shows that the SMED method can reduce set-up time by 51 seconds.

Abstract

The cause of global warming occurring in the world originates from the transportation sector, particularly Internal Combustion Engine (ICE) vehicles using fossil fuels. As a response, the Indonesian government has enacted regulations aimed at accelerating the adoption of electric vehicles. Electric vehicles developed in Indonesia encompass two-wheeled, three-wheeled, four-wheeled, and other types that operate by utilizing electrical energy stored in the vehicle's battery. One notable development involves the conversion of ICE motorcycles into electric motorcycles. This study seeks to assess the investment feasibility of implementing convertible motorcycles from economic, environmental, and social perspectives. The economic aspects are evaluated by calculating net present value (NPV) and payback period (PP), with the study's results demonstrating the economic viability of implementing convertible motorcycles. Furthermore, environmental considerations involve the comparison of chemical substances emitted as pollutants, with the results indicating the feasibility of this approach due to its potential to reduce air pollution. Lastly, the social aspect encompasses the review of potential impacts should converted electric motorcycles be produced on a large scale. The success of implementing convertible motorcycles necessitates the collaboration of various stakeholders, including the government, small and medium enterprises, electricity service providers, and the awareness of the public.
