Recent studies show limited research on the development of learning media that effectively addresses critical thinking, communication, collaboration, and creativity(4C) characteristics. However, there is an urge for nurturing the 4C characters of vocational high school graduates in the 21st Century, especially critical thinking. Hence, this study aims to develop and discover the feasibility, usability, and effectiveness of critical thinking-based interactive learning media for Basic Mechanical Engineering. This study used the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) development concept. The information design in developing the learning media was based on critical thinking aspects by Facione in ATC21S. The critical-thinking-based interactive learning media (CTBILM) were developed for mobile learning which can be used in IOS and Android. The alpha test showed promising results, especially from material experts. In addition to that, the User Acceptance Test (UAT) also shown a significant score making CTBILM quite feasible. We also argue that the significant change in student critical thinking from the statistical t-test on pretest and posttest are due to CTBILM.

Dampak dari tidak optimalnya manajemen sampah pada Kelurahan Jakamulya yang selalu terkena banjir akibat sampah dan Situ Wo yang tidak bisa menampung air. Upaya-upaya untuk mengelola sampah dari sumbernya sudah dilakukan dengan bank sampah namun belum optimal. Tujuan Program Kemitraan Wilayah Kota Bekasi adalah peningkatan partisipasi masyarakat dalam pengelolaan Sampah dengan konsep 3R (reuse, recycle, reduce).   Berdasarkan hasil penerapan program PKW dapat disimpulkan bahwa operasional  Bank sampah Mutiara Pondok Suryamandala di Kelurahan Jakamulya Kota Bekasi berbasis TPS 3R menjadi kunci penanganan sampah berbasis masyarakat (komunal) sangat efektif untuk pengelolaan sampah yang langsung masyarakat sebagai pengelola plus (pemilik home industri). Tanpa system komunal ini mustahil sampah dapat diatasi dengan tuntas atau berkelanjutan. Membudayakan cara pembuangan sampah yang baik mulai dari lingkungan rumah tangga hingga dengan cara menyerahkan sampah ke Bank Sampah adalah metoda efektif di tingkat masyarakat yang akhirnya akan memandirikan masyarakat dalam mengelola sampahnya sendiri. Menata TPS 3R menjadi pusat pemanfaatan sampah organik dan anorganik secara maksimal merupakan program pengelolaan sampah berbasis komunal yang secara pasti akan memotong mata rantai distribusi sampah dari TPS 3R ke tempat pembuangan akhir.
