| dc.description.abstract | Penelitian ini bertujuan untuk mengetahui pengaruh variasi waktu pencampuran terhadap konduktivitas listrik komposit berbahan dasar polipropilen (PP) dan karbon aktif (KA) menggunakan mesin internal mixer. Polipropilen memiliki sifat isolator, sedangkan karbon aktif memiliki kemampuan konduktif tinggi. Proses pencampuran yang optimal diharapkan mampu menghasilkan distribusi karbon aktif yang merata, sehingga membentuk jalur konduktif dalam matriks polimer. Variasi waktu pencampuran yang diuji adalah 15, 20, dan 25 menit dengan komposisi KA sebesar 0%, 5%, dan 15%. Hasil menunjukkan bahwa seluruh sampel belum mencapai konduktivitas listrik yang terukur, ditandai dengan nilai hambatan listrik tak hingga. Analisis densitas menunjukkan bahwa waktu pencampuran 15 menit dengan komposisi KA 5% memberikan struktur paling rapat dan berpotensi konduktif. Temuan ini menunjukkan pentingnya pengaturan parameter proses untuk mendapatkan material komposit konduktif yang optimal dalam aplikasi teknologi ramah lingkungan seperti fuel cell. This study aims to determine the effect of varying mixing time on the electrical conductivity of polypropylene (PP) and activated carbon (KA)-based composites using an internal mixer. Polypropylene has insulating properties, while activated carbon has high conductive capabilities. The optimal mixing process is expected to produce an even distribution of activated carbon, thus forming a conductive path in the polymer matrix. The mixing time variations tested were 15, 20, and 25 minutes with KA compositions of 0%, 5%, and 15%. The results showed that all samples had not reached measurable electrical conductivity, indicated by an infinite electrical resistance value. Density analysis showed that a mixing time of 15 minutes with a 5% KA composition provided the densest and potentially conductive structure. These findings demonstrate the importance of setting process parameters to obtain optimal conductive composite materials in environmentally friendly technology applications such as fuel cells. | en_US |
