This study aims to produce chemical-based e-Module POGIL (Process Oriented Guided Inquiry Learning) on the material oxidation-reduction reaction as a viable source of student learning. This research method using research and development or research and development (R & D). Subjects in this study were students of SMK class X. Data analysis techniques using an assessment analysis of 10 validators consisting of 5 material and language experts, as well as 5 media experts. Analysis of expert validation test questionnaires, Student and teacher trials using questionnaires that were adopted from Puskurbuk and issued by BSNP. Applications used in the manufacture of e-Module is 3D PageFlip Professional 1.7.7. The results of the study show that: (1) Assessment of experts as a whole is obtained in the range of 70% to 90% with good to excellent interpretation, (2) Assessment of teachers and students on a small scale and large scale as a whole increases in the range 80% 90% with good to good interpretation. Thus, it can be concluded that the e-Module POGIL material based chemical oxidation-reduction reactions are very well developed and already eligible for use in the learning process and can be used as a source of independent study students.

Abstract Research and Development has been carried out to produce a valid, practical and effective e-module flipbook model of Problem-Based Learning (PBL) to improve learning outcomes on redox material. This type of research is Research and Development (R&D) adopting the ADDIE development model. The e-module trial was carried out in Class X MIPA at SMA Negeri 12 Banjarmasin for the 2020/2021 Academic Year. Validation and observation sheets, readability questionnaires, response questionnaires, and learning outcomes tests were occupied to collect the data. In analyzing the data, descriptive analysis was used. The results showed that the developed e-module has met the following criteria: (1) Validity; the value of the content feasibility aspect of 91% (very valid), presentation of 96% (very valid), language of 95% (very valid), and media of 94.5% (very valid). (2) Practicality, seen from the readability results of e-module on individual tests of 3.5 (very good) and small groups of 3.4 (very good), student responses to e-modules of 3.3 (very good), and responses to teacher teaching activities using e-module of 3.7 (very good). (3) Effectiveness, views and learning outcomes of knowledge with an N-gain value of 0.80 (high) and the result of learning attitudes of 83.26 (very good).

Penelitian ini dilakukan untuk mengetahui peningkatan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia melalui penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) (POGIL) di kelas 11 SMAN 8 Pekanbaru. Penelitian ini menggunakan One Group Pretest-Posttest Design yang diadakan di SMAN 8 Pekanbaru pada tahun akademik 2017/2018. Objek penelitian adalah XI MIA 1 yang terdiri dari 32 siswa. Pengumpulan data siswa menggunakan teknik tes pretest dan posttest. Keberhasilan pembelajaran dalam meningkatkan kemampuan berpikir kritis siswa ditunjukkan oleh peningkatan kriteria berpikir kritis dari hasil pretest dan posttest yang menganalisis persentase skor berpikir kritis. Hasil penelitian menunjukkan bahwa ada peningkatan kemampuan berpikir kritis siswa. Siswa mengalami peningkatan dari kategori berpikir kritis sangat rendah ke kategori sangat tinggi dengan persentase 15,625%, dari kategori rendah ke kategori sangat tinggi adalah 40,625%, dari kategori rata-rata ke kategori sangat tinggi adalah 9,375%, dari kategori sangat rendah hingga kategori tinggi adalah 12,5%, dan dari kategori rendah ke kategori tinggi adalah 21,875%. Berdasarkan analisis data, dapat disimpulkan bahwa penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) mampu meningkatkan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia di SMAN 8 Pekanbaru.   The research was held to determine the improvement of student’s critical thinking ability on Thermochemistry subject through implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy at 11th Grade of SMAN 8 Pekanbaru. This research used One Group Pretest-Posttest Design which held in SMAN 8 Pekanbaru at academic year of 2017/2018. The object of research is XI MIA 1 that consist of 32 students. The data collection of students used test technique which are pretest and posttest. The success of learning in improvement of student’s critical thinking ability is showed by improvement of criteria of critical thinking from pretest and posttest results that analyzed the score percentage of critical thinking. The result of research showed that there was an improvement of student’s critical thinking ability. The students have an increase from the very low category of critical thinking to very high category with percentage of 15,625%, from low category to very high category is 40,625%, from average category to very high category is 9,375%, from very low category to high category is 12,5%, and from low category to high category is 21,875%. Based on data analyze, it can be concluded that implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy is able to improve student’s critical thinking ability on Thermochemistry subject at SMAN 8 Pekanbaru.

Opportunistic bacteria Pseudomonas aeruginosa is one of the major concerns as an etiological agent of nosocomial infections in humans. Many virulence factors used to colonize the human body are the same as those used by P. aeruginosa to thrive in the environment such as membrane transport, biofilm formation, oxidation/reduction reaction, among others. P. aeruginosa origin is mainly from the environment, the adaptation to mammalian tissues may follow a source-sink evolution model; the environment is the source of many lineages, some of them capable of adaptation to the human body. Some lineages may adapt to humans and go through reductive evolution in which some genes are lost.  The understanding of this process may be critical to implement better methods to control outbreaks in hospitals.

Penelitian ini bertujuan untuk mengetahui peningkatan prestasi belajar peserta didik dengan penerapan strategi process oriented guided inquiry learning (POGIL) pada pokok bahasan senyawa hidrokarbon. Penelitian ini dijalankan di kelas XI SMA Negeri 10 Pekanbaru. Metode penelitian yang digunakan adalah eksperimen dengan desain penelitian randomized control group pretest-posttest. Instrumen penelitian berupa soal pilihan ganda materi senyawa hidrokarbon yang telah diuji validitas dan reliabilitasnya (r = 0,953). Sampel dalam penelitian ini terdiri atas kelas eksperimen (n = 36) dan kelas kontrol (n = 35) sebagai kelas kontrol. Kelompok eksperimen diberi perlakuan dengan penerapan strategi POGIL, sedangkan kelompok kontrol tanpa penerapan strategi POGIL. Analisa data dilakukan menggunakan uji-t pihak kanan. Berdasarkan hasil analisis data diperoleh thitung > ttabel (3,07 ˃ 1,67) dengan α = 0,05, dk = 69 sehingga dapat disimpulkan bahwa penerapan strategi POGIL dapat meningkatkan prestasi belajar peserta didik pada pokok bahasan senyawa hidrokarbon.
