30th East Java Student Competency Competition (LKS) - Chemistry, 2022

Represented SMKN 1 Sukorejo in the Chemistry category of the 30th East Java Student Competency Competition (LKS) in 2022. After passing the school-level selection, I achieved the top position in Wilker 2 East Java and advanced to the provincial-level competition.

The competition involved written examinations, laboratory practice, chemical product preparation and analysis, technical report writing, and product presentation. In the practical assessment, I formulated transparent solid soap using used cooking oil as a raw material, followed by product analysis and evaluation based on the applicable Indonesian National Standard (SNI) for transparent solid soap.

This experience strengthened my foundation in chemical analysis, product formulation, laboratory techniques, quality evaluation, technical documentation, and scientific communication. It also trained me to work accurately and systematically while meeting specified product standards and completing technical tasks within a limited timeframe.
