The Inovasi Teknik Kimia (INTEKA) journal focuses upon aspects of chemical engineering: chemical reaction engineering, environmental chemical engineering, material and food engineering . The INTEKA is an research journal and invites contributions of original and novel fundamental research. The journal aims to provide a forum for the presentation of original fundamental research, interpretative reviews and discussion of new developments in chemical engineering. Papers which describe novel theory and its application to practice are welcome, as are those which illustrate the transfer of techniques from other disciplines. Reports of carefully executed experimental work, which is soundly interpreted are also welcome. The overall focus is on original and rigorous research results which have generic significance.
