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.

Abstract

Supply chain risk management plays a pivotal role for businesses, regardless of their size—be it large industries or Micro, Small, and Medium Enterprises (MSMEs). Even in MSMEs, supply chain risk management is crucial to mitigate potential risks stemming from various events. Consider BS, an MSME producing bread in Cilegon city, established in 2020, aspiring for market expansion. However, BS faces internal challenges such as fluctuating flour availability, recurring machine breakdowns twice a month, and consumer returns due to order discrepancies. Thus, this study aims to analyze supply chain risks to proactively prevent these recurrent events. The method employed here is the House of Risk. Through data processing, 32 risk events were identified by mapping supply chain activities based on the SCOR principle. From these events, 18 risk agents were derived, highlighting critical areas that require resolution. Employing a Pareto diagram, six priority risk agents have been identified for immediate resolution.
