Abstract

Air sumur merupakan sumber air utama yang digunakan masyarakat indonesia untuk kebutuhan sehari-hari. Salah satu upaya yang dapat dilakukan untuk menjaga kualitas air sumur dengan mengidentifikasi keberadaan logam berat terutama timbal (Pb), maka dari itu dilakukannya analisa kadar Pb pada air sumur warga di kecamatan Tenayan Raya Pekanbaru melalui analisis menggunakan Spektrofotometri Serapan Atom (SSA). Spektrofotometri Serapan Atom dipilih untuk menganalisis kadar timbal (Pb) dalam penelitian ini karena mempunyai sensitivitas serta akurasi yang memadai untuk dilakukannya analisis logam terlarut di dalam sampel air. Timbal (Pb) adalah logam berat dengan sifat toksisitas yang tinggi. Paparan timbal dalam jumlah yang tinggi dapat mengakibatkan berbagai masalah kesehatan kronis, dimulai dari kulit pucat, penurunan tekanan darah, diare hingga kerusakan hati dan ginjal bahkan menyebabkan karsinogenik. Hasil penelitian yang telah dilakukan di peroleh kadar Pb pada sampel air sumur sebesar 0,086 mg/L. Kadar air ini berada diatas batas maksimum yang diizinkan untuk air minum (0,01 mg/L) dan air untuk keperluan hygiene sanitasi (0,05 mg/L) berdasarkan Peraturan Menteri Kesehatan Republik Indonesia Nomor 492/MENKES/PER/IV/2010 dan Peraturan Menteri Kesehatan No32Tahun2017. Pencemaran air sumur dapat disebabkan oleh limbah rumah tangga, perkotaan, pemukiman, pasar, pabrik, jalan, industri, pertanian dan sumberl ainnya yang mencemari badan air. Penelitian ini menekankan pentingnya pengawasan kualitas air sumur untuk melindungi kesehatan masyarakat dari risiko paparan timbal. Dengan demikian, diperlukan upaya lebih lanjut untuk mengontrol dan memperbaiki kualitas air agar memenuhi standar kesehatan yang ditetapkan.

Abstract

Inflamasi merupakan pertahanan tubuh saat terjadi rangsangan berbahaya pada jaringan tubuh. Namun inflamasi berlebih dapat menyebabkan rusaknya jaringan dan penyakit degeneratif. Enzim Cyclooxygenase-2 (COX-2) memiliki peran penting dalam proses inflamasi sehingga penghambatan ennzim tersebut dapat menjadi pengendalian inflamasi. Non-steroidal anti-inflammatory drugs (NSAID) menjadi pengobatan konvensional untuk mengatasi inflamansi namun terkadang memiliki efek samping yang tidak diinginkan. Penelitian ini betujuan untuk mengeksplorasi interaksi senyawa dari ekstrak daun kacang gude (Cajanus Cajan) dengan Cyclooxygenase-2 (COX-2) dalam upaya menemukan obat antiinflamasi dengan pendekatan in silico menggunakan perangkat lunak MOE. Hasil dari penelitian ini diperoleh 2 senyawa sebagai ligan terbaik yakni ?- selinene dan ?-tocopherol dengan nilai energi ikatan masing-masing 1.2433 kcal/mol dan 1.4352 kcal/mol dan nilai RMSD masing-masing -6.4444 Å dan -8.1138 Å. Selain itu, pengujian Lipinski Rule of Five menunjukkan hasil yang sesuai aturan dan memenuhi kriteria obat. Namun, untuk mengonfirmasi potensi aktivitas antiinflamasi dari senyawa tersebut secara menyeluruh, diperlukan validasi lebih lanjut melalui studi in vitro dan in vivo, guna membuktikan efektivitas biologis serta keamanannya sebelum dapat dikembangkan sebagai kandidat obat antiinflamasi.

Abstract

The material of the basic laws of chemistry is an important foundation in understanding various advanced concepts in chemistry, especially those related to quantitative calculations such as the concept of moles. However, the abstract and mathematical characteristics of the material are often an obstacle for students in understanding the concept thoroughly. The purpose of this research is to develop a guided inquiry-based learning system integrated with flipped classroom assisted by Discord application on the material of basic laws of chemistry. The research employed the Educational Design Research (EDR) method using the Plomp model, which includes three stages:preliminary research, development or prototyping phase, and assessment phase, with limitations up to the small group trial stage (prototype IV). The research subjects consisted of 3 lecturers, 2 chemistry teachers, and 9 students of class XI SMAN 8 Padang. Needs analysis revealed that chemistry learning remains abstract and heavily mathematical, leading to student difficulties and misconceptions. To address this, a learning approach was designed incorporating three levels of multiple chemical representations (macroscopic, submicroscopic, and symbolic) integrated flipped classroom that supports independent learning, with guided inquiry syntax. Discord was selected as the supporting platform due to its comprehensive features that facilitate both synchronous and asynchronous learning. The product was tested through validation by experts and evaluation of students. The results of content validity of 0.89 and construct validity of 0.93 indicate that the product is valid. The practicality value of 93% obtained from the analysis of the practicality questionnaire of teachers and students with a very practical category. These findings suggest that the developed learning system is appropriate for use in chemistry education and can effectively help students independently and meaningfully understand the basic laws of chemistry. Furthermore, this study supports the implementation of the Merdeka Curriculum and the integration of technology-based learning.
