Abstract

Reaction rate material involves both realistic and abstract concepts that require visualization and experimentation to better understand the influencing factors. Therefore, the use of a Project-Based Learning (PjBL) model is essential to connect theoretical knowledge with real-world contexts, enabling the creation of innovative and effective learning products that foster students’ creative thinking skills. This study aims to develop an e-LKPD using Liveworksheets based on PjBL for reaction rate material and to evaluate its effect on students’ creative thinking. The research employs the Lee and Owens Research and Development model using interviews, questionnaires, and pre-test–post-test instruments. Validation results from material and media experts indicate a high level of feasibility, while teacher assessments and student responses show strong satisfaction. The pre-test and post-test results reveal a significant improvement in creative thinking skills, with an N-Gain score of 0.6502. Overall, the developed e-LKPD is conceptually valid, practically applicable, and effective in enhancing creative thinking in chemistry learning, particularly in understanding reaction rate concepts.

Abstract

Cognitive abilities are very important for students to master because they relate to students' way of thinking at various cognitive levels. The facts that occur in the field are that teachers only train cognitive abilities up to understanding level (C2), students' cognitive ability scores are low, and students are rarely involved in practical activities. For this reason, it is necessary to address how to improve students' cognitive abilities. The scientific approach and integrated science learning are considered to be able to improve students' cognitive abilities. Integrated science learning is science learning that is holistic and meaningful for students so that it is easier to understand. Apart from that, a scientific approach can be presented using experimental methods. Therefore, this research aims to determine the effect of the scientific approach in integrated science learning on students' cognitive abilities. This research uses a weak experimental design method, the one group pretest-posttest design type. The research was conducted at one of the state junior high schools in Bandung City with 25 class VII H students as samples. The research instruments used were pretest and posttest cognitive ability questions. The pretest and posttest results of students' cognitive abilities were analyzed using the paired t-test, obtaining a significance value of 0.0005 on sig. (2-tailed), this shows that the scientific approach in integrated science learning with the webbed model has a significant effect on increasing students' cognitive abilities. ABSTRAKKemampuan kognitif sangat penting untuk dikuasai oleh siswa karena berkaitan dengan cara berfikir siswa dalam berbagai tingkatan kognitif.

Abstract

Abstract Alzheimer's contamination is a neurodegenerative sickness brought about by a decline in the blend of acetylcholine because of the breakdown of acetylcholine into choline and the determination of acidic corrosive by the compound Acetylcholinesterase (Hurt). Compounds known to have heartbeat restraining developments are promising medications for the treatment of these contaminations. In this investigation, in-silico studies were done on the blend found in Miana (Coleus) further to see whether this combination could be utilized as a remedial application in the treatment of Alzheimer's illness utilizing sub-nuclear docking procedures. From the consequences of the examination, it is realized that the Pyrazolopyridine compound is the best medication contender with a limiting energy and stable limitation benefit of - 6.96 kcal/mol and 7.95 µm separately, with hydrogen securities happening in the destructive development of amino SER 293.   Keywords:          Alzheimer’s; In Silico; Miana   Abstrak Penyakit Alzheimer adalah infeksi neurodegenerative, dan terjadi karena menurunnya kombinasi asetilkolin dampak dari penguraian asetilkolin menjadi kolin dan derivasi asam asetat oleh senyawa Asetilkolinesterase (Hurt). Larutan yang diketahui memiliki gerakan penghambatan denyut merupakan obat yang menjanjikan untuk pengobatan infeksi ini. Dalam eksplorasi ini, studi in-silico dilakukan pada campuran yang ditemukan di Miana (Coleus) selanjutnya untuk melihat apakah campuran ini dapat digunakan sebagai aplikasi pengobatan dalam pengobatan penyakit Alzheimer dengan menggunakan strategi docking sub-atomik.
