Abstract

Abstract: This Research aims to develop Student Worksheet Based on Problem
Solving in Colloid of Chemistry in Senior High School Subject in terms of valid based
on the feasibility aspect of content, language, serve and graphic. This type of research
is research and development (R and D) with reference to the development process of 4-
D model. The subject of this research is student worksheet based on problem solving.
Instrument of data collection are validation given by three validators, and from analysis
of data obtained by the validity aspect of content, language, serving and graphic
consecutively by 90%, 83.33%, 88.33% and 95.83% with valid category. Based on the
results of data analysis can be concluded that the Activity Sheet Students (LKPD) based
problem solving generated declared valid and can be used on subjects SMA subject of
colloid chemistry. Based on the results of data analysis can be concluded that student
worksheet based on problem solving has been valid and can be used in Senior High
School Chemistry Subject of colloid.
