The application of PBL-STEM can encourage students to be independent in the learning process and emphasize the process of thinking critically and analytically to seek and find answers to a problem in question. This study used a true–experimental design with the Posttest Only Control Design type. The population in this study were all students of class XI SMA Kristen Sunodia Samarinda for the academic year 2022/2023 divided into 2 classes. This study aims to determine the effect of PBL-STEM in improving students' critical thinking skills. Sampling was done by cluster random sampling technique. The instruments used to measure students' critical thinking skills in chemistry were post-test questions, teacher and student observation sheets, and student response sheets (questionnaire). Data analysis was performed by t-test. The results of the t-test with Mann-Whitney obtained sig. (2-tailed) in both classes is 0.00 <0.05, it is concluded that Ha accepted the statement that there is an effect of the application of PBL-STEM on the critical thinking skills of class XI students at Christian Senior High School Sunodia Samarinda regarding reaction rates. The results of the teacher and student activity sheets in the experimental class were both in very good categories, as well as the student response to PBL-STEM learning, namely 77.2% of students agreed with the application of PBL-STEM in learning which can train students' critical thinking skills. This research discusses the analysis of how effective the influence of PBL and STEM integration is to improve critical thinking skills on reaction rate material so that this research can be used as a reference for applying PBL-STEM to other chemistry topics.

Calcium Sulfate Hemihydrate (CSH) with uniform morphology and high crystallinity were successfully prepared by a precipitation-hydrolysis method in a concentrated sulfuric acid solution containing fishbone-derived carbon. The CSH was produced by carbonization of fishbone powder at 500 °C for 2 h, followed by sulfonation with concentrated sulfuric acid for 3 h. The solid mixture was washed until the pH of 2, then left at room temperature for 3 days. Physical properties of synthesized CSH were characterized using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), wavelength dispersive X-ray fluorescence (WDXRF), Scanning Electron Microscope (SEM), nitrogen adsorption-desorption isotherm, and melting point test. It is concluded that the CSH were formed due to hydrolysis of fishbone-derived carbon in a moderately concentrated sulfuric acid solution of carbon-derived fishbone and crystallization into a fibrous octa calcium phosphate (OCP) form. In this research, effect of crystal growth time, effect of pH during the crystal growth, and effect of volume of the solution were also investigated.

The oil palm is a widely cultivated plant recognized by the public for its production of industrial raw materials for everyday use. Oil palm is rich in potential antioxidant activity, primarily due to its high content of phenolic and flavonoid compunds. This research aimed to assess the levels of total phenolic and flavonoid compunds in oil palm fruit. The extract sample was examined using the UV-Vis Spectrophotometry method, with the total phenolic measured at 744.8 nm, the total flavoinoid content at 440. The findigs indicated that the total phenolic content in the oil palm fruit extract was 1.46 mg/L while the total flavonoid content was 5.81 mg/L.

Pembelajaran kimia di sekolah sering kali menghadapi tantangan akibat kurangnya variasi dan diferensiasi dalam proses, produk, dan konten pembelajaran. Siswa memerlukan pendekatan pembelajaran yang sesuai dengan kebutuhan, minat, dan kemampuan yang berbeda-beda. Kajian literatur ini mengeksplorasi peran Artificial Intelligence (AI) sebagai solusi untuk mendukung strategi pembelajaran berdiferensiasi pada mata pelajaran kimia di sekolah. Kajian literatur menggunakan narrative literature review bertujuan untuk mengidentifikasi dan merangkum artikel-artikel yang telah dipublikasikan sebelumnya tanpa ada kritikan terhadap artikel yang ditinjau. AI memiliki peranan besar dalam meningkatkan pembelajaran kimia, namun peran guru tetap penting. Kombinasi antara kecerdasan buatan dan pendekatan manusia dapat memberikan hasil pembelajaran yang optimal. AI memiliki kelebihan dalam menyajikan materi personal dan mendukung pembelajaran berbasis diferensiasi. Kajian literatur ini diharapkan dapat memberikan panduan bagi pendidik dan pengembang kurikulum untuk memanfaatkan AI secara optimal dalam mencapai pembelajaran diferensiasi yang efektif dan inklusif di bidang kimia.
