Streptococcus mutans bacteria are bacteria that colonize the surface of teeth which have a role in the formation of dental caries. The leaves of ciplukan (Physalis angulata L.) are rich in polyphenols, alkaloids, and flavonoids which are reported to have quite good antimicrobial activity. The aim of this research was to determine the effect of ethanol extract of ciplukan leaves and stalks mouthwash on Streptococcus mutans bacteria. This rese arch method is purely laboratory experimental using Streptococcus mutans bacteria culture. The antibacterial power test used the liquid dilution method which was then followed by solid dilution with an incubation period of 28 ° C. The statistical analysis test used a descriptive test. The results showed that the ethanol extract of the leaves and stems of ciplukan (Physalis angulata L.) had a minimum inhibitory level (MIC) and a minimum kill rate (MBC) at the same concentr...

Kenyataannya masih banyak guru yang mendominasi proses pembelajaran sehingga aktivitas siswa menjadi rendah. Keadaan demikian terjadi juga di SMP Kurnia Bogor. Berdasarkan observasi dan wawancara dengan Kepala Sekolah dan Guru, diperoleh informasi bahwa proses pembelajaran pada umumnya masih didominasi oleh guru. Belum nampak adanya kolaborasi antar siswa maupun guru dalam proses pembelajaran. Hal inilah yang ingin diubah dan diperbaiki agar pembelajaran menjadi lebih bermakna serta memberikan hak belajar kepada seluruh peserta didik. Solusi yang ditawarkan adalah memberikan pendampingan untuk mengembangkan Learning Community (komunitas belajar) melalui implementasi Lesson Study atau sering dikenal dengan istilah LSLC (Lesson Study for Learning Community). Kegiatan diawali dengan sosialisasi mengenai tuj...

This study aimed to determine the mollusks' diversity in Menganti Beach, Kebumen. The research was conducted from April to May 2020, using a survey method and purposive sampling technique. Sampling was undertaken at three stations with the belt transect method. The results revealed 37 species with 1767 individuals from the Class Bivalvia, Gastropods, and Polyplacophora. Based on the diversity index value H '= 3.3, station 1 with the rocky sand substrate is the best for mollusks' habitat. The H' value at station 1 shows the highest diversity that the base substrate is dominated by sand and rocks, which are very supportive of mollusks. It is supported by the evenness value (E), which indicates evenly distributed species, and dominance value (D), which does not indicate a species' dominance. The a-biotic parameters ...

The methods used is completely randomized design (CRD) with six level factor: 0%, 8%, 16%, 24%, 32%, and 40%. In every treatments is repeated four times, the observed variables are number of rosella flowers and wet weight rosella flowers. The calculation of ANOVA to number of rosella flowers and wet weight rosella flowers show that there is an influence in giving jackfruit banana weevil MOL to number of rosella flowers but there isn't an influence in giving jackfruit banana weevil MOL to wet weight flowers. Optimal concentration of jackfruit banana weevil MOL to number of rosella flowers is 24%.
