%X Learning chemistry at school currently requires students to be more
active in teaching and learning activities. Educators are required to
apply contextual chemistry learning in knowledge construction.
Therefore, students need learning resources related to everyday life so
that students are helped in the learning process. Soap is one of the
products related to chemical materials that exist in everyday life. Soap
is a cleaning tool for chemically reacting sodium, alkaline, and fatty
acids. The main ingredients, NaOH and fat, can vary in the
saponification. Researchers researched the effect of NaOH variations
on the physical quality of solid soap with a combination of oil as a
ix
student learning resource, which aims to determine the appropriate
NaOH levels so that they can produce good quality soap products and
know the material related to the soap making process according to the
curriculum. The research was conducted using two methods. First, the
effect of variations in NaOH levels on the quality of the physical
properties of solid oil combination soap was carried out using
experimental methods and descriptive analysis. Second, an analysis of
the curriculum distribution of school chemistry learning materials and
soap making as student learning resources was carried out using the
literary study method. Based on the research results, the soap-making
process that produces good quality soap after carrying out a pH test,
foam height test, and organoleptic test is a soap with a NaOH content
of 32%. Based on an analysis of the curriculum distribution of school
chemistry learning materials and an analysis of tea as a student learning
resource. The chemistry learning material relevant to soap making is
arranged coherently so students can easily remember and understand
the previous and subsequent lessons.
