| dc.description.abstract | Penelitian ini bertujuan untuk menganalisis pengaruh variasi tekanan proses hot press terhadap konduktivitas listrik pada komposit polipropilen/karbon aktif sebagai material calon plat dwikutub pada fuel cell. Sampel dibuat dengan beberapa variasi komposisi polipropilen dan karbon aktif, serta diuji pada tekanan 2 MPa, 4 MPa, dan 6 MPa. Hasil pengujian menunjukkan bahwa seluruh sampel, baik dengan maupun tanpa penambahan karbon aktif, tidak menghasilkan nilai konduktivitas listrik yang terukur. Kondisi ini diduga disebabkan oleh tingginya porositas dan belum terbentuknya jalur konduktif antar partikel karbon aktif dalam matriks polipropilen. Peningkatan tekanan hot press memang dapat meningkatkan densitas material, namun belum cukup untuk membentuk struktur penghantar listrik yang efektif. Temuan ini menegaskan perlunya optimasi parameter proses dan desain cetakan agar distribusi partikel lebih merata serta jalur konduktif dapat terbentuk dengan baik dalam aplikasi material komposit konduktif. This study aims to analyze the effect of variations in hot press pressure on the electrical conductivity of polypropylene/activated carbon composites as candidate materials for bipolar plates in fuel cells. Samples were made with several variations in polypropylene and activated carbon compositions, and tested at pressures of 2 MPa, 4 MPa, and 6 MPa. The test results showed that all samples, both with and without the addition of activated carbon, did not produce measurable electrical conductivity values. This condition is thought to be caused by high porosity and the lack of conductive pathways between activated carbon particles in the polypropylene matrix. Increasing the hot press pressure can indeed increase the material density, but it is not enough to form an effective electrically conducting structure. These findings emphasize the need for optimization of process parameters and mold design to ensure more even particle distribution and proper conductive pathways in the application of conductive composite materials. | en_US |
