Preparedness is an important effort to reduce disaster risk. It can be measured through knowledge and attitude parameters. Previously, an integrated science textbook on smog theme using networked model with EPBL has been developed to enhance students' smog preparedness. The aim of this research is to evaluate the effectiveness of textbook on the enhancement of students' smog preparedness. Quasi experimental research with One Group Pretest and Post-test design was carried out with 38 seventh grade students assigned randomly as research subjects. The obtained data were analyzed using descriptive statistic, N-gain, and effect size. The result shows that more than 75% of all students achieved prepared and highly prepared level on both of preparedness parameters. The enhancement of preparedness on both of parameters based on N-Gain is in the moderate category. The effect size of textbook on the enhancement of students' smog preparedness on both of parameters is in the moderately strong category. The implication of this research is that the developed integrated science textbook is effectively used to enhance students' smog preparedness. © 2019 Published under licence by IOP Publishing Ltd.
