Abstract

Telah dilakukan penghitungan konduktivitas panas (k) untuk mengetahui sifat isolator panas dari papan sekam padi dengan metode plat rangkap. Papan sekam padi dibuat dengan variasi diameter sekam dan kadar resin. Sekam padi setelah digiling divariasikan menjadi tiga kelompok ukuran, yaitu sekam berdiameter kecil dari 1 mm, di antara 1 mm hingga 2 mm dan lebih besar dari 2 mm. Kadar resin divariasikan menjadi tiga kelompok, yaitu + 20 %, + 45 % dan + 75 % . Hasil penelitian menunjukkan bahwa harga konduktivitas panas masing-masing sampel papan sekam sangat kecil dan bervariasi. Papan sekam padi yang mempunyai harga konduktivitas panas yang paling rendah atau memiliki sifat isolator panas paling tinggi adalah papan sekam padi dengan diameter sekam kecil dari 1 mm dan kadar resin + 20 % dengan k = 0,187 (J s-1 m-1 K-1 ), sedangkan papan sekam padi yang mempunyai harga konduktivitas panas yang paling tinggi atau sifat isolator paling rendah adalah papan sekam padi yang diameter sekamnya lebih besar dari 2 mm dan kadar resin + 75 % dengan konduktivitas panas k = 0,329 (J s-1 m-1 K-1 ).
