The use of pesticides to kill wild plants that disturb crops is a problem that is quite severe in the world. Based on data from a study at the International Academy of Ecology and Environmental Sciences that discusses the use of pesticides, it was found that the amount of pesticide use rose from 1990 to 2015. The main problem caused by the use of herbicides was side effects that caused the land to become hard or unfavorable. Again and will cause it to be difficult for microbes to decompose nutrients. These side effects can be minimized by using herbicides efficiently by spraying herbicides only on weeds. Efficient spraying can be done by making a rover-shaped robot that will eradicate weeds by using image processing and spraying the herbicides to the weeds that have been detected. The problem that arises from the existing rover is that the rover to fall is high when the road is rocky or needs to climb uneven paths. Because of this deficiency, the author implements the Rocker-bogie based on the multi-terrain mechanism. The proposed rocker-bogie can improve rover stability with a maximum height of obstacle as high as 4 cm for climbing and 18.1 cm for descending.

Percobaan ini bertujuan untuk melakukan uji aktivitas enzim α-amilase dalam hidrolisis pati, menjelaskan faktor-faktor yang mempengaruhi aktivitas enzim, dan menghitung nilai Km dan Vmax aktivitas enzim serta penentuan jenis inhibitor. Uji aktivitas α-amilase dilakukan dengan metode reaksi kualitatif dan uji colorless point. Kemudian, pengaruh kadar substrat dan pengaruh kadar inhibitor terhadap aktivitas enzim dilakukan dengan metode spektrofotometri.

Parijoto (Medinilla speciosa (Reinw ex BL)) is one of the Indonesian indigenous plants widely used as traditional medicine. A previous study showed that ethanol and methanol extracts of Parijoto fruit could inhibit T47D breast cancer cells. This study explores the antioxidant and cytotoxic activities of Parijoto fruit extract and fractions on HeLa cell line. The fruits were extracted using ethanol 70% and fractionated by hexane and ethyl acetate. Furthermore, the fraction was analyzed for secondary phytochemical metabolite content using thin-layer chromatography and staining reagents. The antioxidant and cytotoxic activities were determined using the DPPH scavenging assay and the MTT assay, respectively. The ethanol extract and fraction contained flavonoid and tannin compounds. Ethanol extract, ethanol fraction, and ethyl acetate fraction of Parijoto fruit had an antioxidant activity with IC50 values of 77.3, 88.64, and 46.61 μg/mL, respectively. Ethyl acetate fraction showed the hi...

SMK Muhammadiyah Minggir memiliki jurusan farmasi. Siswa-siswa jurusan farmasi membutuhkan pengetahuan yang lebih tentang teknologi farmasi. Teknologi farmasi meliputi industri farmasi, parameter obat berkualitas, CPOB, dan macam bentuk sediaan farmasi serta teknologi produksinya. Teknologi farmasi merupakan hal yang awam di kalangan mereka karena dalam kurikulum jurusan farmasi di SMK lebih banyak dan difokuskan pada farmasi pelayanan. Namun, di era pesatnya perkembangan teknologi saat ini lulusan SMK jurusan farmasi dituntut mampu memiliki setidaknya pengetahuan dasar tentang teknologi farmasi agar dapat mengikuti perkembangan zaman. Melalui penyuluhan teknologi farmasi yang dilakukan oleh tim pengabdian masyarakat Universitas Muhammadiyah Yogyakarta, selain terjalin hubungan yang baik sesama Amal Usaha Muhammadiyah (AUM), perguruan tinggi dapat memberikan sumbangsih ilmu pengetahuan dari hasil risetnya kepada sekolah menengah dalam hal ini SMK sebagai bentuk pemenuhan kewajiban t...
