ABSTRACT The concepts of hydrolysis and buffer solutions have abstracts related to pH. This concept plays a role in the processes that occur in our bodies and in everyday life. Learning hydrolysis and solution materials requires experiments or practicum, the implementation of practicum is very dependent on the existence and completeness of the laboratory. With advances in technology in the field of ICT, there are many programs available that can be used to design ICT-based practicums (virtual labs). Virtual laboratory can overcome the limitations of laboratories, tools and materials, time and can save costs.This development research aims to determine the feasibility (theoretical and practical) of the developed virtual laboratory for hydrolysis material and buffer solutions. The virtual laboratory for hydrolysis and buffer solutions was developed using the Adobe Flash6 Professional program.This type of research is development research. The product developed is a virtual laboratory using the Adobe Flash6 Professional program for hydrolysis and Basic Chemistry II buffering materials in chemistry education study programs. This virtual laboratory development research uses the ADDIE model.The results of material validation and virtual laboratory media for hydrolysis and buffer solutions were 91% (very good) and 90% (very good). Student learning outcomes average 79.5 (very good)So it can be concluded that the developed virtual laboratory of hydrolysis material and buffer solutions is theoretically feasible and practical and can improve student learning outcomes.

Purpose of the Study: This study aims to analyze the impact of the Problem-Based Learning (PBL) model on the development of students’ responsibility character in Chemistry education, with a specific focus on the challenging topic of atomic structure among 11th-grade high school students. Amid increasing concerns about character education in STEM subjects, this study seeks to fill the gap by exploring how active learning models influence affective outcomes alongside cognitive achievement. Methodology: A mixed-methods explanatory design was employed, incorporating a quasi-experimental approach with pretest-posttest control groups. Quantitative data were collected through self-assessment questionnaires, peer evaluations, and teacher observation sheets, while qualitative insights were gathered via semi-structured interviews and thematic analysis of student reflections. The triangulation of data sources provided a comprehensive view of how PBL implementation affects student responsibility. Main Findings: The findings revealed that students in the experimental group demonstrated significant improvements in their responsibility character compared to the control group. Higher posttest scores reflected positive behavioral changes in engagement, discipline, and task accountability during Chemistry learning activities. Qualitative data further supported that PBL encouraged students to take ownership of their learning process, collaborate effectively, and complete tasks with greater autonomy and diligence. Novelty/Originality of this Study: This research offers a novel perspective by applying PBL not only as a cognitive learning strategy but also as a tool for character development in complex Chemistry topics. It advances the understanding of integrative pedagogical models that simultaneously nurture academic proficiency and essential life skills, particularly responsibility, in secondary science education.
