The purpose of this study is to describe the stages of making the performance assessment instrument and analyzing the results of the feasibility test of the online-based performance assessment instrument on the Basic Chemistry practicum. The method used is research and development. The results show that research phases include chemical material analysis, making performance assessment instruments, website creation, validation and limited trials. Validation is done to material and media expert validators, limited trials conducted to students and assistants of Basic Chemistry practicum. Validation of making of performance assessment instrument has value of rcount 0,95, while result of validation of making website of instrument of performance assessment has value of rcount 0,84. It shows that online-based performance assessment instrument on Basic Chemistry practicum interpretation is valid and has high feasibility of assessment of expert validator. The results show that the feasibility test based on a limited trial give good response with an average of 97.5% and 98.8%. The result of the percentage of the feasibility test indicates that the online-based performance assessment instrument on the Basic Chemistry practicum is eligible for use. Making this website is expected to facilitate lecturers in conducting the assessment of the performance of students at the time of practicum.
