Abstract

The research is motivated by the issue faced by motorcycle users, namely the wear and tear of brake shoes, which can reduce braking effectiveness and increase the risk of accidents. The main objective of this study is to analyze the structural properties of motorcycle brake shoes with three different materials (aluminum alloy, cast iron, and magnesium alloy) and brake linings made of different carbon variants (alumina-carbon composite, carbon ceramics, and carbon fiber) under static pressures. Additional design aspects including weight and production cost are also evaluated during the material selection process for the motorcycle’s brake shoe and brake lining. The 3D modeling of the brake shoe and lining was done in Solidworks using measurement data from a Coordinate Measuring Machine (CMM). The finite element analysis was performed using ABAQUS software. Considering the results from the finite element analysis, weight, and economic aspects, the study found that aluminum alloy (Al alloy) and carbon composite can be suitable materials for brake shoes and brake lining. The Al alloy brake shoe provides 62.7% weight saving while exhibiting good structural properties under static load and a moderate increase in production cost compared to cast iron. Similarly, brake lining with alumina-carbon composite showed the least deformation under static load while maintaining modest production costs compared to the other carbon variants.

Abstract

The rise of e-commerce has revolutionized transaction patterns and marketing strategies in Indonesia. Its ease of access, extensive promotions, and operational efficiency provide significant advantages for large-scale producers in reaching consumers. However, this advancement poses serious challenges for Usaha Mikro, Kecil, dan Menengah (UMKM)that still operate traditionally. The imbalance in competitiveness, declining customer visits to offline markets, and threats to local economic sustainability emerge as key issues. This study adopts a qualitative approach through a literature review to analyze the impact of large producers’ marketing strategies via e-commerce from the perspective of Islamic economic law. Findings indicate that Sharia principles—such as justice, transparency, and social responsibility—demand ethical standards in competition, ensuring that digital marketing practices do not marginalize MSMEs. Therefore, regulatory and educational interventions from the government are necessary to promote inclusive digital transformation while maintaining economic balance through the application of Islamic values in online business practices.
