DEVELOPMENT OF PROJECT BASED LEARNING TASK MODELS FOR ANALYTICAL CHEMISTRY ONLINE TUTORIALS IN FOOD TECHNOLOGY PROGRAM UNIVERSITAS TERBUKA

Abstract

So far, online tutorial assignments only cover questions that require theoretical completion. In the concept of learning Analytical Chemistry which requires the achievement of competence in mastering the basic concepts of methods and tools in carrying out chemical analysis, this is not sufficient. This study aims to explain the development of a project-based learning (PjBL) model for tutorial assignments in online tutorial learning assistance session for the Analytical Chemistry course in Food Technology study program. Developing methods carried out by the provision of structured assignments including practical nstructions then instructions for the preparation of detailed activities have been done. Materials have been founded from natural ingredients in the food category that are commonly encountered in everyday life, namely the extraction of Virgin Coconut Oil (VCO) from coconuts. The media for delivering these activities is documentation in the form of photos or videos. From this structured real practice, students are proven to be able to carry out VCO extraction projects independently with an average accuracy level of above 90%. Not only the level of accuracy, but some students are also able to calculate the percentage of VCO yield obtained from whole coconuts. The distribution of grades is also maximal when compared to theoretical assignments. From this real experience, students are expected to be able to gain knowledge not only limited to theory but also knowledge from real things that they have done themselves. Thus, from the experience of all the five senses will produce in-depth knowledge for each individual student.
