Abstract

This study aims to analyze the waste management system in Tanjungpinang City and the innovations made by the Ganet Landfill Technical Implementation Unit (UPTD) in reducing environmental pollution. The main problem faced is the increasing amount of waste along with population growth, which has an impact on the landfill's capacity. This study uses a qualitative descriptive approach by examining the waste management process from collection, transportation, sorting, to final processing. The results show that waste management at the Ganet landfill has implemented various innovations such as composting, processing plastic waste into fuel through pyrolysis, and utilizing methane gas as an alternative energy source. In addition, waste reduction programs such as waste banks and community outreach also support waste control efforts. However, the continuous increase in waste volume poses a challenge to the sustainability of the existing management system. Therefore, it is necessary to strengthen policies, increase community participation, and develop sustainable innovations in waste management in Tanjungpinang City.

Abstract

Pembelajaran matematika sering kali di angggap sulit oleh banyak siswa maka dengan menggunakan metode dan media pembelajaran yang tepat maka akan menjadi menyenangkan maka dari itu Penelitian ini mengevaluasi efektivitas penggunaan media manipulatif (benda konkret seperti biji-bijian dan stik es krim) sebagai bagian dari proses evaluasi formatif di kelas II SD. Masalah utama yang ditemukan adalah rendahnya pemahaman siswa jika evaluasi hanya dilakukan melalui soal cerita tertulis. Melalui metode Penelitian Tindakan Kelas (PTK), hasil menunjukkan peningkatan ketuntasan belajar dari 40% pada pra-siklus menjadi 85% pada siklus II. Penelitian menyimpulkan bahwa evaluasi yang melibatkan aktivitas fisik dan benda nyata membantu siswa SD menjembatani pemahaman abstrak ke konkret.
