Abstract

This development research aims to develop practical guidelines for animal development based on science process skills on embryogenesis observation material. This study uses a 4D development model which is carried out in 4 stages, namely: 1) the define stage defines the product requirements to be developed. 2) the design stage (design) designing prototypes and storyboards on the guide. 3) the development stage is realizing the storyboard then validating the feasibility of the product which is carried out by material experts and media experts. 4) the dissemination stage was only carried out in a large group trial. Trials were conducted to find out student responses to the guidelines developed, trials were conducted on 92 students who contracted animal development courses. Based on the data analysis, it was obtained that the average material validation was 86.03%, and the media validation was 95.72%, the average percentage of student responses was 85.23%, so it can be concluded that the practicum guide is feasible to use..

Abstract

Platyhelminthes (flatworms) are simple triploblastic animals that represent an important stage in the evolution of organ systems. This article discusses the development, organization, and adaptation of organ systems in major classes of Platyhelminthes, including Turbellaria, Trematoda, and Cestoda. Using a literature review method, the study examines the morphology and physiology of flatworms based on scientific journals and biology references. The results show that although Platyhelminthes lack specialized circulatory and respiratory systems, they possess functional digestive, excretory, nervous, and reproductive systems. Their body organization reflects an early stage of organ system specialization in invertebrates, making them an important model for understanding animal evolution, adaptation, and biological complexity.
