Abstrak : Ilmu kimia termasuk dalam rumpun sains dan merupakan salah satu cabang sains yang mencakup konsep, aturan, hukum, prinsip dan proses. Proses dan pembelajaran kimia dapat menghasilkan manusia yang berkualitas dengan menunjukkan kesadaran kimia dan keterampilan berpikir tingkat tinggi yang dapat memunculkan sumber daya manusia yang mampu berpikir kritis, berpikir kreatif, mengambil keputusan dan memecahkan masalah. Studi ini bertujuan untuk mengetahui pengaruh implementasi bahan ajar kimia umum online terintegrasi media dalam meningkatkan HOTS mahasiswa. Penelitian ini termasuk penelitian kuasi eksperimen dengan menggunakan desain faktorial 2×2. Hasil penelitian menunjukkan bahwa terdapat perbedaan HOTS antara kelompok mahasiswa yang diberi pembelajaran menggunakan bahan ajar kimia umum online terintegrasi media dibandingkan kelompok mahasiswa yang diberi pembelajaran tanpa bahan ajar kimia umum online. Terdapat perbedaan HOTS mahasiswa ditinjau dari kemampuan awalnya yaitu kelompok mahasiswa yang memiliki kemampuan awal tinggi memperoleh nilai HOTS lebih tinggi dibandingkan mahasiswa yang memiliki kemampuan awal rendah. Tidak terdapat interaksi antara pembelajaran dengan kemampuan awal terhadap HOTS mahasiswa. Hal ini sekaligus mengindikasikan bahwa penerapan pembelajaran yang diterapkan dan kemampuan awal yang dimiliki mahasiswa secara terintegrasi tidak berpengaruh signifikan terhadap HOTS mahasiswa. Kata kunci : Bahan Ajar Online, Media, Kimia Umum, Kemampuan Awal, HOTSEnglish translation. Abstract: Chemistry belongs to the science group and is one of the branches of science that includes concepts, rules, laws, principles and processes. Chemical processes and learning can produce qualified humans by demonstrating high-level chemical awareness and thinking skills that can give rise to human resources capable of critical thinking, creative thinking, decision-making and solving problems. This study aims to find out the influence of the implementation of integrated online chemical teaching materials media in improving student HOTS. This research included quasi-experimental research using 2×2 factorial design. The results showed that there was a difference in HOTS between the group of students who were given learning using integrated online general chemistry teaching materials compared to the group of students who were given learning without general chemistry teaching materials online. There is a difference in student HOTS judging from the initial ability, namely the group of students who have high initial ability to get higher HOTS scores than students who have low initial ability. There is no interaction between learning and initial ability for student HOTS. This also indicates that the application of applied learning and the initial abilities possessed by students in an integrated manner have no significant effect on student HOTS. Keywords : Online Teaching Materials, Media, General Chemistry, Initial Ability, HOTS

Cancer is a disease characterized by uncontrolled cell division and the ability of these cells to invade other biological tissues, either by direct growth in adjacent tissues or by migration of cells to distant sites. The purpose of this study was to determine the class of secondary metabolites contained in the ethanol extract of cocoa leaves and their cytotoxicity by looking at the LC50 value using the Brine Shrimp Lethality Test (BSLT) method. This research includes phytochemical screening of ethanol extract and the BSLT method by looking at the number of deaths of Artemia salina leach larvae (LC50). The results of phytochemical screening tests showed that the cocoa leaves contained flavonoids, alkaloids, tannins, saponins, steroids, and glycosides. The cytotoxicity test with probit analysis showed an LC50 value of 269,15 µg/mL, so it was concluded that the ethanol extract of cocoa leaves was toxic and had potential as an anticancer.

Practical activities are an important part of chemistry education. The chemistry practicum faced a variety of issues, including a lack of school facilities for performing the practicum and improperly managed chemical waste. As a reason, the research aims to develop and validate the feasibility of a green chemistry-based laboratory manual, as well as to assess how students and teachers respond to the final product. Research and Development (R&D) using the ADDIE model was employed as the research methodology. The reaction rate is the subject of this study. The laboratory manual developed is very feasible to implement in chemistry learning, according to the results of the analyzed data. Media expert lecturers provide an average score of 90 percent (very feasible) and material expert lecturers provide a score of 93,9 percent (very feasible). Students and teachers responded enthusiastically to the developed laboratory manual, with an average student reaction of 85 percent (very good) and a teacher response of 93,4 percent (very good).

Learning is required to always be creative in presenting learning materials such as using learning models that can foster student’s enthusiasm in participating learning process, so that students are happy and interested in exploring the lesson in the hope that their learning outcomes will be better. This study aims to (1) determine the increase in student learning outcomes taught with the Problem Based Learning model based on critical thinking is higher than the Direct Instruction model (2) to find out whether there is an influence of the Problem Based Learning model based on critical thinking on learning activities students on acid base material. From the results of the study, it was found that student learning outcomes in the experimental class were 77%, while those in the control class were 62%. The result of the difference in increasing learning outcomes between the two classes is 15%. From the t distribution data obtained t-table = 1.676 while based on calculations obtained price tcount = 3.73 means that Ho is rejected and Ha is accepted, based on this analysis means there is an influence of the Problem Based Learning model Learning based on critical thinking towards student learning activities on Acid-Base material.Pembelajaran dituntut untuk selalu kreatif dalam menyajikan materi pembelajaran seperti menggunakan model pembelajaran yang dapat menumbuhkan semangat siswa dalam mengikuti proses pembelajaran, sehingga siswa senang dan tertarik untuk mendalami pelajaran dengan harapan hasil belajarnya menjadi lebih baik.
