Salah satu materi pokok dalam mata kuliah Kimia Umum-II yang memiliki kajian yang cukup luas, sarat dengan konsep dan bersifat abstrak adalah kelarutan/hasil kali kelarutan. Materi pokok tersebut akan lebih tepat diajarkan dengan PBL menggunakan animasi maupun peta konsep sehingga mahasiswa mudah memahmi dan menjadikan perkuliahan lebih bermakna. Selain itu, faktor lain yang juga berpengaruh terhadap pencapaian hasil belajar mahasiswa adalah kemampuan berpikir kritis (KBK) mahasiswa. Hasil penelitian disimpulkan bahwa: 1) terdapat pengaruh yang signifikan penerapan PBL menggunakan animasi terhadap hasil belajar kimia mahasiswa yaitu rata-rata hasil belajar kimia mahasiswa yang diajarkan dengan PBL menggunakan animasi lebih tinggi dibandingkan hasil belajar mahasiswa yang diajarkan dengan model PBL menggunakan peta konsep; 2) terdapat pengaruh yang signifikan KBK mahasiswa terhadap hasil belajar kimia mahasiswa yaitu rata-rata hasil belajar kimia mahasiswa yang memiliki KBK tinggi lebih baik atau lebih tinggi dibandingkan hasil belajar kimia mahasiswa yang memiliki KBK rendah; 3) tidak terdapat pengaruh yang signifikan interaksi antara penerapan PBL menggunakan animasi maupun peta konsep ditinjau dari KBK mahasiswa terhadap hasil belajar kimia yang dicapai mahasiswa.

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.

Sap is a very important commodity in the industrial pharmacy, perfumes and medicines contain abundant active compounds of frankincense making resin widely used. Extraction and solvation processes play an important role in the production of stable frankincense extract. One of the widely used preparations is suspension, which is an active compound that does not dissolve in water to become soluble. The purpose of this study was to determine the manufacture of a suspension of frankincense gum extract as an active pharmaceutical ingredient. The method used was precipitation using cosolvent, surfactant and agitation process at 1500 rpm at a temperature of 40oC. Various comparisons were analyzed for phytochemical screening, viscosity and pH. in the most stable formula to be tested, the size of the suspension particles found that frankincense extract was soluble in distilled water with an average particle size is 4.80205 μm. .
