Abstract

Akumulasi sampah plastik menyebabkan pencemaran tanah dan perairan, memicu polusi udara, serta berkontribusi terhadap peningkatan emisi gas rumah kaca yang memperburuk pemanasan global dan perubahan iklim. Volume sampah plastik yang terus meningkat tidak diimbangi dengan sistem pengelolaan yang efektif, sehingga kapasitas Tempat Pembuangan Akhir (TPA) semakin terbatas dan pencemaran lingkungan meluas hingga ke lautan. Daur ulang plastik yang masih rendah, hanya berkisar 5–10%, menunjukkan perlunya inovasi pengolahan limbah. Sosialisasi dan pelatihan pembuatan paving block dengan campuran plastik PET menjadi alternatif inovatif untuk meningkatkan nilai guna sampah plastik sekaligus mengurangi dampak negatif terhadap lingkungan. Kegiatan ini menghasilkan paving block mutu C dengan f’c 12,5–15 MPa dengan campuran plastik yang memiliki daya serap air yang lebih rendah dibandingkan dengan paving normal, karena sifat plastik yang hidrofobik. Paving block dengan campuran plastik memberikan pengaruh minimal pada perendaman, sedangkan paving mormal peningkatan serapan lebih signifikan akibat struktur pori yang lebih terbuka.

Abstract

Limbah plastik merupakan salah satu permasalahan lingkungan yang serius karena sulit terurai dan volumenya terus meningkat. Bank Sampah Berkah Srikandi merupakan salah satu bank sampah pengolahan limbah plastik yang belum optimal di dalam pengelolaan sampah, sehingga nilai ekonominya masih rendah. Program Pengabdian kepada Masyarakat ini bertujuan memberikan solusi melalui sosialisasi, pelatihan, dan daur ulang limbah plastik sebagai bahan campuran pembuatan paving block ramah lingkungan. Metode pelaksanaan meliputi persiapan, sosialisasi mengenai bahaya limbah plastik, pelatihan penggunaan mesin pencacah, dan praktik pembuatan paving block dengan campuran limbah plastik PET. Hasil kegiatan menunjukkan antusias dari warga untuk mengetahui bagaimana proses pengolahan limbah plastik menjadi material campuran dalam pembuatan paving block karena hal ini masih inovasi yang baru bagi masyarakat. Di dalam praktik pembuatan paving block digunakan 1,64 kg plastik PET yang sudah di cacah untuk bahan campuran pembuatan paving block. Produk paving block yang dihasilkan memiliki daya serap air relatif tidak signifikan, berbeda dengan paving normal yang lebih porus sehingga sangat baik untuk digunakan dan memiliki nilai ekonomis serta ramah lingkungan. PkM ini membangun kesadaran masyarakat terhadap konsep ekonomi sirkular serta membuka peluang usaha mikro berbasis daur ulang plastik.

Abstract

The development of technology is increasingly rapid, especially in the world of machinery or industry, so improving the competence of student graduates is very important to prepare the workforce needed in the industrial environment. SMTK Sabu Raijua East Nusa Tenggara is currently unable to have a craft technique based on science and technology that supports the industrial era 4.0. as an initial competency in the production process for small and medium industries in the field of manufacturing technology and engineering. Therefore, the Universitas Kristen Indonesia through the PkM Team, conducted CNC milling machine programming training for teachers and students. This training aims to improve the abilities or competencies of students in preparation for entering the industrial world which is packaged in extracurricular lessons. The method of implementing this PkM activity uses the training and evaluation method. This training activity includes selecting milling eyes, a simple product design process on Vetric software, creating G-Code files on Vetric software, calibration between system coordinates and machine coordinates, and operating CNC machines. The training was attended by 36 participants consisting of students and teachers of SMK HKBP Pematang Siantar on January 27-29, 2025. After training and observation, it was concluded that participants were able to produce simple products such as key chains based on CNC machines according to the standards determined by the team.

Abstract

The program aimed to implement a learning aid that facilitates collaborative and enjoyable mathematics learning for seventh-grade students at State Junior High School 80 Jakarta. A total of 64 students participated in the program. This initiative was a collaborative effort between the Department of Mechanical Engineering and the Mathematics Education Program of Universitas Kristen Indonesia. The program consisted of three main stages: (1) a preliminary needs assessment through school observations and discussions with the principal and mathematics teachers, (2) the design and development of the Math Thinker instructional media and its accompanying learning module, and (3) the implementation of the instructional media in mathematics classroom activities. The implementation results overall mean score of 3,28 out of 4, indicated that students demonstrated positive responses toward the use of the Math Thinker instructional media. The learning activities successfully promoted collaborative group learning and created an engaging and enjoyable classroom environment. Furthermore, the instructional media optimized the mathematics learning process by encouraging active student participation and enhancing students' enjoyment of learning mathematics.
