Motivasi merupakan suatu dorongan atau alasan yang menjadi dasar semangat seseorang untuk melakukan sesuatu, sedangkan strategi pembelajaran merupakan alat untuk mencapai suatu tujuan tertentu dalam kegiatan belajar mengajar. Berbicara mengenai strategi pembelajaran dalam lingkup sekolah dasar sebagaimana kita ketahui selama ini bahwa pembelajaran hanyaberpusat pada guru (teachercentered) yaitu guru yang lebih agresif dan aktif dalam proses pembelajaran yang berorientasi pada target penguasaan materi dan pengembangan intelektual siswa dengan penekanan pengembangan aspek kognitif. Hal inilah yang kemudian menjadi dasar masalah peserta didik tidak antusias dalam mengikuti proses pembelajaran di kelas, sehingga guru dituntut untuk menerapkan strategi pembelajaran sesuai dengan materi secaraaktif dan menyenangkan untuk menumbuhkan motivasi belajar anak. Dalam hal ini, salah satu alternative strategi pembelajaran yang bisa diaplikasikan oleh guru di sekolah dasar yakni learning by doing. Learning by doingini merupakan belajar yang dilakukan secara langsung (belajar dengan melakukan), sehingga materi ajar yang disampaikan guru akan lebih melekat dalam diri peserta didik. Bentuk pengajaran dalam konteks learning by doing yakni: 1) menumbuhkan motivasi belajar anak. 2) mengajak anak didik beraktivitas. 3) mengajar dengan memperhatikan perbedaan individual. 4) mengajar dengan umpan balik. 5) mengajar dengan pengalihan. 6) penyusunan pemahaman yang logis dan psikologis.

Medinilla speciosa (M. speciosa) Blume is a plant originating from Mount Muria, Kudus District, Central Java, Indonesia. Its fruit has been used by the local community to treat mouth sores, diarrhea, inflammatory, hyperlipidemia, cancer, bacterial infection and nutrients for pregnant women. However, the antibacterial activity against Salmonella typhi (S. typhi) and Shigella dysentriae (S. dysentriae) is yet unknown. Thus, the aim of this study was to determine the antibacterial activities of M. speciosa fruit extracts against clinical strain of S. typhi and S. dysentriae. Plant determination and sample preparation were conducted. The fruits of M. speciosa were extracted by gradual maseration using n-hexane, ethyl acetate and methanol as solvents. Phytochemicals were screened by Fransworth method. Antibacterial activity was determined using agar well diffusion. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values and comparison study of antibacterial activity were determined. The results showed that all of the extracts exhibited antibacterial activities, with the greatest activity shown by the methanol extract. This extract was more effective against S. dysenteriae than S. typhi, as evidenced by the largest inhibition diameter and lowest MIC (25 mg/mL) and MBC (50 mg/mL) values. With regard to the results of phytochemical screening, the antibacterial activity of methanol extract could be due to the presence of alkaloids, flavonoids, polyphenols, quinones, saponins and tannins. From the comparative antibacterial activity value indicated that in order to give the same inhibition diameter with 1 ppm of chloramphenicol, 312.3 ppm methanol extract is needed. It can be conclude that M. speciosa fruit has a potential to be developed as natural antibacterial agent, especially to treat bacillary dysentery
