Penelitian ini dilakukan karena aktivitas belajar siswa belum optimal sehingga siswa terlihat kurang antusias dalam mengikuti kegiatan pembelajaran. Selain itu, alokasi waktu yang dibutuhkan guru masih kurang sehingga mengakibatkan transfer pengetahuan kepada siswa tidak optimal. Penelitian ini bertujuan untuk mengetahui pengaruh learning cycle 5E terhadap aktivitas belajar pendidikan agama islam siswa kelas XI IPS di SMA Negeri 4 Kota Bukittinggi. Pendekatan yang digunakan dalam penelitian ini adalah quasi experiment. Populasi penelitian ini adalah semua siswa kelas XI di SMA Negeri 4 Kota Bukittinggi dan sample di ambil dari 2 kelas XI yaitunya XI IPS 2 dan XI Ips 3. Pengumpulan data dengan menggunakan observasi angket. Data dianalisis dengan menggunakan analisis deskriptif dan uji t untuk pengujian hipotesis. Hasil penelitian menunjukan rata-rata posttest kelompok eksperimen adalah 81,14 dan rata-rata posttest kelompok kontrol adalah 69,23. Hasil analisis dengan menggunakan Independent Sample T-test antara kelompok eksperimen dan kelompok kontrol diperoleh nilai t-hitung sebesar 89,779 dan nilai t-tabel sebesar 2,750, serta taraf signifikansi sebesar 0.000. Jadi, dapat disimpulkan bahwa aktivitas belajar siswa yang belajar menggunakan model pembelajaran learning cycle 5E berpengaruh aktif dan lebih baik daripada aktivitas belajar siswa yang belajar menggunakan model pembelajaran konvensional di kelas XI di SMA Negeri 4 Kota Bukittinggi.

This study aims to find out whether there is an influence of the Problem Based Learning-Computational Thinking (PBL-CT) model on analytical thinking skills in terms of students' interest in Natural Sciences subjects. This research was conducted at the Kalam Kudus Christian Middle School in Malang in the 2022/2023 academic year. The design used in this study was a non-equivalent group design quasi-experiment. Retrieval of data using ten essay questions which are made according to indicators of analytical thinking ability and students' interest in science is measured by using a questionnaire.  Data analysis was carried out by the Two Way Anova parametric test. Based on the results of the analysis carried out, the results were obtained: (1) there were differences in analytical thinking skills between students who were taught using the Problem Based Learning and Problem Based Learning - Computational Thinking (PBL-CT) learning models with a significance <0.05. (2) there is no difference in the ability to think analytically between students who have a high, medium, and low interest in learning science as shown by a significance value of 0.748 > 0.05. (3) there is an interaction between Problem Based Learning - Computational Thinking (PBL-CT) on students' analytical thinking skills in terms of students' interest in natural science subjects with a significance value of <0.05

Penelitian ini adalah penelitian komparatif dengan metode quasi experiment. Penelitian ini bertujuan untuk membandingkan hasil belajar Teorema Pythagoras siswa dalam dua kelas. Kelas yang pertama disebut Kelas Eksperimen dengan perlakuan (treatment) adalah model pembelajaran Berbasis Masalah, sedangkan kelas kedua disebut Kelas Kontrol dengan perlakuan adalah model Pembelajaran Langsung. Berdasarkan hasil penelitian yang dilaksanakan di kelas VIII SMP Negeri 5 Tabukan Utara, diperoleh perbedaan hasillbelajar siswa  yang signifikan antara siswa yang menggunakan modellPembelajaran Berbasis Masalah dengan siswa yang menggunakan model Pembelajaran Langsung. Rata-rata data post-test yang terkumpul dari Kelas Eksperimen, yaitu   lebih dari  rata-rata data post-test di Kelas Kontrol yang hanya .

A woman who is in pregnancy often experiences many changes, both physical changes and psychological changes. These changes can cause anxiety and increase anxiety. In third trimester pregnant women, the level of anxiety becomes more serious and intensive along the birth time schedule. Feelings of anxiety can cause tension in the mind and physique, pelvic muscles and lower uterine segment muscles; thus, this tension can disrupt the birth process. The impact of anxiety is so big for the mother and the fetus, so the interventions are needed to reduce anxiety in pregnant women. The purpose of this research was to find the effect of birthing preparation services. The research approach used a quantitative approach with preexperimental research design. This design involved pretest and posttest one group design. Samples in this study was 69 third trimester pregnant women. The data collection technique used a questionnaire was taken before experiment and after experiment. Data analysis used paired T test. The results showed that there was a significant difference in the level of anxiety between before and after being given pregnancy preparation services with (p value = 0.000) (p value = 0.000) or (p <0.05).

Background: General anesthesia is the act of administering a combination of drugs during surgery with the aim of reducing consciousness and eliminating pain in the patient. There are 2.5% of patients experiencing intra-anesthesia complications including hypotension.Objective: To determine the comparison of giving fluid loading and reducing inhaled gas with giving ephedrine to prevent hypotension in patients in central surgery installations.Research Metod: Quantitative method with experimental research type with quasi-experiment. This research used a Pretest-Posttest Two Group Design with 22 respondents.Research Result: Based on test statistics, it is known that the results of the Independent Sample T Test data analysis test show a P value (>0.05), namely H0 is accepted. Based on this test, it was concluded that there was no significant relationship between administering fluid loading and reducing inhaled gas with administering ephedrine to prevent hypotension.Conclusion: Based on this research, researchers are more effective in using fluid loading and reducing inhaled gas than administering ephedrine in the ETT technique for general anesthesia.
