Abstract

In the present study examined the influence of red fruit extract (RFE) on fertilization rate and development of mice embryos during the pre-implantation stage. The application of RFE dose 0 ml/head/day, 0.05 ml/head/day, and 0.1 ml/head/day for seven days were conducted to examine its influence at the level of fertilization, then the application of RFE was continued during 0-3 days stage of pregnancy (0 day of pregnancy is the formation of the vaginal plug). The super-ovulation of the white mice was done by injecting of 5 IU PMSG and hCG (48 hours after PMSG), folowed by mating the females with males with ratio 1:1. The single-cell-embryos were collected 20 hours after the injection of hCG. The eggs were then fixed and stained before examinating the normal fertilization of eggs (formation 2 pronucleus). The morula and blastocysts were collected 84 hours after injection of hCG. The influence of the RFE with dose 0.1 ml on normal fertilization rate (formation 2 PN), significantly higher (46.01%) compared with dose 0.05 ml (37.51%) and controlled (16.38%). However, the influence of RFE with dose of 0.05 ml and 0.1 ml on the growth of pre-implantation stage embryos may inhibit the growth of mice embryos during the pre-implantation stage in vivo.

Abstract

Kemampuan berpikir kritis dan sikap sosial siswa kelas SMAN 8 Mataram masih rendah. Penerapan model pembelajran RQA-CPS dilakukan untuk meningkatkan kemampuan berpikir kritis dan sikap sosial. Penelitian ini berjenis eksperimen semu dan dilakukan pada dua kelas yang telah diketahui homogenitasnya. Data kemampuan berpikiris kritis diperoleh dari nilai pre-test dan post-test dan sikap sosial dari angket. Data berpikir kritis dianalisis dengan ANACOVA menggunakan SPSS versi 25 dan data sikap sosial dianalisis secara deskriptif. Penelitian ini menunjukkan bahwa terjadi peningkatan kemampuan berpikir kritis (hasil yang signifikan dari skor pretest terhadap posttes untuk kemampuan berpikir kritis dengan hasil sebesar 0.000 untuk p < 0.01) dan sikap sosial peserta didik. Model pembelajaran krreatif terbukti mampu membuat aktivitas peserta didik di kelas menjadi lebih baik dalam aspek menerima pendapat teman, memaksa teman untuk menerima pendapatnya, memberi solusi untuk pendapat yang bertentangan serta dapat bekerja sama dengan teman yang berbeda status sosial, suku dan agama.
