Abstract. Chemical equilibrium is one of the chemistry topics that students still find difficult to understand because it is abstract and dynamic, while instructional materials capable of visualizing concepts and relating them to real-life contexts remain limited. This study aimed to describe the validity of an SCCrT e-module based on wetland Socio-Scientific Issues (SSI) for chemical equilibrium. This study employed a quantitative descriptive design focusing on evaluating the validity of the developed e-module. The e-module was developed by integrating wetland contexts into contextual chemistry learning. The validation process involved five validators, consisting of two lecturers from the Chemistry Education Study Program at Universitas Lambung Mangkurat and three chemistry teachers from three senior high schools in Banjarmasin. The research instrument was an e-module validation sheet covering four aspects: content feasibility, presentation feasibility, language feasibility, and media and visual design. The validation data were analyzed using Aiken's V index. The results showed that the validity indices for content feasibility, presentation feasibility, language feasibility, and media and visual design were 0.86, 0.93, 0.85, and 0.97, respectively. The average Aiken's V index was 0.90, indicating that the e-module was valid. Therefore, the SCCrT e-module based on wetland SSI for chemical equilibrium was considered valid and feasible for use in chemistry learning.

Temuan menunjukkan bahwa siswa memersepsikan lingkungan laboratorium secara positif, terutama pada aspek kejelasan aturan, keterkaitan praktikum dengan pembelajaran di kelas, serta kondisi material. Sebaliknya, kesempatan untuk melakukan eksplorasi dan penyelidikan yang lebih terbuka masih dipersepsikan sebagai relatif terbatas, Rendahnya capaian open-endedness menjadi dasar untuk mempertimbangkan pengembangan kegiatan praktikum yang memberi ruang lebih besar bagi inisiatif dan pengambilan keputusan siswa secara bertahap tanpa mengurangi aspek keselamatan dan struktur laboratorium.

Abstract. The chemistry laboratory learning environment is a multidimensional construct encompassing social, pedagogical, procedural, and material aspects. This study aimed to describe students' perceptions of the chemistry laboratory learning environment in three public high schools in Banjarmasin using the Chemistry Laboratory Environment Inventory (CLEI). A quantitative descriptive survey was employed, The respondents were 248 students in Grades X and XI who had participated in chemistry laboratory activities. Data were collected using a 35-item CLEI questionnaire covering five dimensions: student cohesiveness, open-endedness, integration, rule clarity, and material environment. The data were analyzed using mean scores and percentage achievement, Rule clarity obtained the highest percentage (84,99%), followed by integration (82,24%) and material environment (81,08%), all categorized as very good, Student cohesiveness reached 74,22% and was categorized as good, whereas open-endedness obtained the lowest percentage (52,13%) and was categorized as sufficient. The findings indicate that students perceived the laboratory environment positively, particularly in terms of rule clarity, the connection between laboratory activities and classroom learning, and material conditions. In contrast, opportunities for more open exploration and investigation were perceived as relatively limited. The lower open-endedness score suggests a need to gradually expand opportunities for student initiative and decision-making while maintaining laboratory safety and structure.
