of the pre-adjusted tread, errors or variations often occur in the measurements taken by the measuring device due to its lack of accuracy. This prevents operators from using the tyre tread and can result in a large amount of scrap and wasted time during the tyre manufacturing process. To overcome this problem, a redesigned tread length measurement system with a higher level of accuracy was created to minimise tread length fluctuations during tyre manufacturing. The results of the tread length measurement procedure using the ENC-1-1-24-N type rotary encoder can function according to the program created. This is validated by the tread length measurement data. The results of the HMI display design and the software created can operate according to the desired instructions. To change the tread length, the operator only needs to enter the number on the HMI panel.
Abstract:Waste management problems in Indonesia have become a crucial challenge, especially in major cities. This study aims to analyze the comparative implementation of waste management policies in Pekanbaru City and Padang City…
using the George C. Edward III policy implementation model. This qualitative research with a literature study approach analyzes four variables: communication, resources, bureaucratic structure, and disposition. The results show that Pekanbaru City faces significant constraints in all four variables, with a waste management achievement of 66.49% and even experiencing a waste emergency status in 2025. In contrast, Padang City achieved 94.02% and received various international awards. This difference is caused by more effective policy communication, massive community empowerment through 182 waste banks, strong fiscal commitment with a budget of Rp 70 billion, solid multi-stakeholder coordination, and a high implementer disposition in Padang City.

environmental impacts, and sustainable solutions related to plastic waste management in both
countries. The method used is qualitative analysis based on secondary data from scientific
literature, reports of international institutions. The results show that Indonesia faces serious
problems in plastic waste management that cause marine pollution to other countries, while
Thailand struggles with the high volume of domestic and imported plastic waste. The
resulting environmental impacts include damage to marine ecosystems, threats to
biodiversity, and human health risks from microplastics. Recommended solutions include the
implementation of national regulations that support sustainability principles, 3R (Reduce,
Reuse, Recycle) strategies, promotion of eco-friendly packaging, and public education to
reduce the use of single-use plastics. The study concludes that regional collaboration among
ASEAN countries is needed to effectively address the plastic waste crisis to protect
ecosystems and human health in the long term.
