Abstract

This study aims to develop a chemistry learning module based on the discovery learning model on chemical kinetics material to improve critical thinking skills of grade XI Phase F high school students. This research is a type of development research (Research and Development) that uses the Plomp development model, which consists of three stages: preliminary research, development (prototyping phase), and assessment phase. The preliminary research stage includes needs analysis and theoretical studies as the basis for compiling the module. Furthermore, in the development stage, the module was validated by five experts to assess the feasibility of content, presentation, language, and contextual aspects. The results showed that the developed module had very high validity with an average Aiken's V value of 0.96. The practicality test showed an average value of 98.50%, which is classified as very practical. The effectiveness test produced a significance value of 0.019 (< 0.05), which indicates a significant increase in learning outcomes after using the module. It can be concluded that this discovery learning module on chemical kinetics is valid, practical, and effective in improving students' critical thinking skills. This module can be an alternative contextual teaching material that encourages active and independent learning at the high school level.

Abstract

This research aims to develop a chemistry learning e-module for acids and bases based on guided discovery learning, incorporating elements of ethnoscience to improve students' literacy and numeracy. The guided discovery learning approach was chosen to encourage students to actively construct knowledge through guidance, while the integration of ethnoscience aims to link chemistry concepts with local wisdom to increase student relevance and understanding. The research method used was Research and Development (R&D) with the 4D development model (Define, Design, Develop, Disseminate). The research instruments included an expert validation sheet, a student response questionnaire, and literacy and numeracy tests. The validation results indicated that the e-module was highly feasible in terms of content, presentation, and language. A limited trial demonstrated significant improvements in students' literacy and numeracy skills after using the e-module. Therefore, this e-module is effective as an alternative learning medium for contextual and meaningful chemistry learning.

Abstract

The Merdeka Curriculum emphasizes students’ ability to understand and apply their conceptual knowledge to solve contextual problems. This study aims to determine the validity, practicality, and effectiveness of an acid–base module based on problem-based learning integrated with TPACK in improving the learning outcomes of Phase F senior high school (SMA/MA) students. The development model used in this research was the 4-D model. The acid–base module was validated by three chemistry lecturers and two chemistry teachers. The practicality test of the module was conducted by three chemistry teachers and 31 students. The effectiveness of the module in improving learning outcomes was analyzed using the N-gain test. The validity test was analyzed using Aiken’s V, which consisted of content and construct validity, yielding results of 0.89 and 0.91, respectively, both categorized as valid. The practicality results from teachers and students were 98.61% and 86.87%, respectively, both in the high category. The N-gain analysis resulted in a value of g = 0.79, categorized as high. Based on the hypothesis test, the calculated t-value was greater than the critical t-value. These findings confirm that the developed acid–base module based on problem-based learning integrated with TPACK is valid, practical, and effective for significantly enhancing students’ learning outcomes.

Abstract

The foundation is the lowest structural component of a building. All the load of the building is supported by the foundation. transferring the load to the soil below. Shallow foundations and deep foundations are two categories of foundations. The Morrissey hotel project uses bored pile foundation, as bored pile foundation is used for buildings in densely populated areas. Bored pile foundation is done by using a drilling machine to drill a hole of a certain depth, then filled with cast concrete and iron bones. This technique is considered to produce a foundation with good durability, especially over a long period of time. Various techniques in bored pile calculation, including conus penetration test (CPT), standard penetration test (SPT), and assessment based on soil shear strength characteristics such as cohesion (c), inner shear angle (?), and soil content weight (?), can be used to determine the bearing capacity of bored piles. The tip bearing capacity (Qb) and the blanket friction bearing capacity (????????), which are determined using the formula, are the two main parts of the bored pile axial bearing capacity.
