PENGEMBANGAN BUKU AJAR BUDIDAYA TANAMAN HORTIKULTURA BERBASIS SOAL HOTS

Abstract

The learning of horticultural crop cultivation subject conducted in the Agrotechnology study program at University of Kahuripan Kediri is still lacking in teaching materials that can stimulate critical thinking, creativity, and understanding among students. In addition, the textbooks used in learning are still not adjusted to the learning outcomes and objectives of the Horticultural Crop Cultivation subject, so that the learning and textbooks used are not in sync. This prompted researchers to conduct research on the development of teaching books based on HOTS questions. This development research is expected to facilitate students, particularly in the Horticultural Crop Cultivation course, to enhance their understanding and critical and creative thinking through the HOTS questions presented in the textbook. The research was conducted using five development stages: information collection, prototype development, textbook production, subject matter expert validation, media expert validation, readability testing, and revision. The results of this textbook development research showed that the expert content validation scored 90%, categorized as highly suitable and very good for use, the expert media validation scored 82.5%, categorized as suitable and permissible for use with revisions, and the textbook readability test resulted in 92.5%, meaning it is highly suitable and can be used in learning. The research contributes to supporting critical thinking-based contextual learning in The Horticultural Crop Cultivation Course. This textbook contains a cover page, foreword, table of contents, and 14 chapters complete with HOTS questions. The materials in this textbook, which are adapted to the RPS, cover the scope of horticultural cultivation, propagation, classification and life cycle of plants, planting patterns, planting methods, weeds, mulch, irrigation, fertilisers, planting media, respiration, pot plants, organic farming, and horticultural plants. This research contributes to supporting contextual learning based on critical thinking in the Horticultural Crop Cultivation course.
