In the covid 19 pandemic era, lectures and practicums cannot be carried out on campus, including the Biology Excursion Study/Biology Field Study course. The learning achievement of this course is that students can design, implement, report, develop learning products and evaluate learning independently through the Project Based Learning model. To achieve this goal, it is necessary to make several adjustments in various aspects, including determining the object of biology, data collection methods, observation locations, data collection and processing techniques, product preparation techniques, and results dissemination techniques. Learning is delivered by lecture of concepts and examples of excursion studies that have been carried out, from proposal preparation to reporting and product preparation. Furthermore, students identify objects and problems to be studied in the environment where they live, followed by the formation of committees and preparation of proposals. All biological objects available around student can be used as learning objects including Ornamental Plants, Medicinal Plants, Macro Fungi, Insects, etc. The problems studied are adapted to the theme of biological problems, and agreed by the students to be adapted to the conditions of residence and available equipment, including the diversity of organisms, classification, structure, function, ecology, etc. The observation methods are adapted to the object of observation. Data were collected by students, then collected and analyzed communally. The research results and discussion are compiled in the form of a book and validated by experts in their fields. Books as research products are registered ISBN in the national library.
