dc.description.abstractPenelitian ini mengkaji pengaruh suhu proses hot press terhadap konduktivitas listrik dan sifat mekanik komposit berbahan dasar polipropilen (PP) dan karbon aktif (KA). Tiga komposisi digunakan (100% PP, 95% PP + 5% KA, dan 85% PP + 15% KA) dengan suhu pemrosesan 160°C, 180°C, dan 200°C pada tekanan 4 MPa selama 15 menit. Hasil pengujian menunjukkan bahwa seluruh sampel masih bersifat isolator, karena karbon aktif belum mencapai ambang pembentukan jalur konduktif. Analisis densitas menunjukkan adanya porositas yang tinggi, yang turut menghambat konduktivitas listrik. Namun, sifat mekanik, khususnya kekuatan lentur, meningkat signifikan dengan penambahan KA, mencapai 127,8 MPa pada komposisi 95% PP + 5% KA. Penambahan KA juga meningkatkan kekakuan namun menurunkan kelenturan material. Penelitian ini merekomendasikan peningkatan kadar KA, suhu proses, serta penggunaan compatibilizer untuk memperbaiki konduktivitas dan struktur mikro komposit. This research examines the effect of hot press processing temperature on the electrical conductivity and mechanical properties of composites made from polypropylene (PP) and activated carbon (AC). Three compositions were used (100% PP, 95% PP + 5% AC, and 85% PP + 15% AC) with processing temperatures of 160°C, 180°C, and 200°C at a pressure of 4 MPa for 15 minutes. Test results show that all samples remain insulating, as the activated carbon has not reached the threshold for forming conductive pathways. Density analysis indicates a high level of porosity, which also hampers electrical conductivity. However, mechanical properties, particularly flexural strength, significantly increased with the addition of AC, reaching 127.8 MPa for the 95% PP + 5% AC composition. The addition of AC also increased stiffness but reduced the flexibility of the material. This study recommends increasing the AC content, processing temperature, and the use of compatibilizers to improve the conductivity and microstructure of the composite.en_US
