Abstract

Water is one of the most fundamental basic needs for human life. However, disparities in the availability of clean water remain a significant challenge in Indonesia. This study aims to develop a water purification device to address this issue. The research method employed was the ADDIE model, which consists of five stages, with this study focusing on analysis, design, and development, which serve as scope of this study. The result of a water purification, named HydroTechPure, utilizes a dual filter system with high quality absorbent materials and is constructed from acrylic materials, enhanced by 3D design technology and Arduino integration. The development of this device aligns with the sixth goal of the Sustainable Development Goals (SDGs), which emphasizes ensuring access to clean water and sanitation for all. HydroTechPure was developed at FabLab Edu UPI. Beyond its primary function, HydroTechPure is envisioned as a tool for integrating STEM based learning, aiming to foster students’ motivation and environmental awareness.

Abstract

This study aims to develop a performance-based assessment instrument to assess students’ Science Process Skills (SPS) for saponification laboratory activities. This research is an instrument development study, consisting of four main stages: planning, development, validation, and pilot testing. A total of twelve 11th grade students from a high school in Bandung participated in pilot testing phase to evaluate the instrument’s reliability. This performance-based instrument covers 27 performance aspects aligned with six SPS indicators: predicting, planning, implementing, observing, communicating, and interpreting. This instrument demonstrates strong content validity, with a CVI of 0.99. Inter-rater reliability was analyzed using Kendall’s W Coefficient. The results show variable agreement results: 2 aspects showed very strong agreement, 3 aspects showed strong agreement, and 11 aspects showed weak agreement. These findings suggest the need to refine several instrument items to enhance inter-rater reliability. The practicality of the instrumen, evaluated through assessors, resulted in a score of 3.35 on a scale of 4.00, indicating the instruments is very practical for further implementation.  Overall, the final product of instrument is valid and practical for assessing students’ SPS in the saponification lab activities, though further improvements are necessary to improve inter-rater agreement.
