Efisiensi dan Kualitas Pembakaran Batu Bata Menggunakan Bahan Bakar Kayu dan Sekam

Abstract

The lack of wood-based burning materials becomes an obstacle in roof tile production processes. Sekam is an alternative burning material that needs to develop due to its burning capacity, large volume, and low price. The objective of this research is to reveal: (1) the difference of efficiency rate in burning process cost between wood-based burning materials and sekam, and (2) the difference of brick quality between those burnt by wood-based burning materials and sekam . Sampling area is determined by using purposive sampling method. It utilizes wood-based burning materials gathered from Dau and Mojosongo, and sekam gathered from Trowulan. Data are collected by using interviews, observation, documentation, and laboratory tests. Data are analyzed by using descriptive method, difference test (t-test), and covarian (F). The analyses results show that (1) there is no significant difference in cost efficiency between wood-based and ­ sekam -used burning processes, and (2) the sekam-used burning process tends to result better brick quality than those using wood-based burning materials.
