For this reason, a pocketbook with teaching materials with local potential is an option. This study aimed to evaluate the practicality of the Pocketbook “Keanekaragaman Lepidoptera di Hutan Mangrof” or “Lepidoptera Diversity in the Mangrove Forest”.

students) with student response questionnaires. The data that has been filled in on the practicality test questionnaire instrument were analyzed quantitatively from the calculation of the total score of indicators and then analyzed by the formula for calculating the practical value. The test results show that the pocketbook which is the result of development research related to the diversity of Lepidoptera in the mangrove forest is categorized as very practical
