Abstract

There is strong correlation between antioxidant activity and hepatoprotector activities in vitro. Macaranga tanarius (MT) is abundant at East Kalimantan and the stems were proven to have antioxidant activity, but efficacy as hepatoprotector in vitro and active compounds is not known. The aim of this research is to examine the active fraction of M. tanarius as antioxidant and or hepatoprotector, also it’s active compounds. MT simplicia were macerated with methanol at room temperature for 3 days and repeated three times. The extracts were fractionated with increasing solvent polarity starting from n-hexane, dichloromethane, ethyl acetate (EtOAc), n-butanol and water. Crude extract and the five fractions were tested in vitro for antioxidant activity using radical scavenging activity assay using 2,2-diphenyl-1-picrylhidrazyl and hepatoprotector  activity. Chromatogram profiles were done for the most active fraction using thin-layer chromatography silica gel 60 F254. Results showed the strongest antioxidant activity was EtOAc fraction with IC50 values (6.24 + 0.96) mg/mL and contained secondary metabolites polyphenols that proven having antioxidant activity. The strongest in vitro hepatoprotector activity was also EtOAc fraction with IC50 values (99 + 2) mg/mL. It can be  concluded that EtOAc fraction of MT stems had antioxidant and hepatoprotector activity in vitro and contained secondary metabolites polyphenols with antioxidant activity.

Abstract

The aim of this research was to determine the level of motivation of beef cattle breeders in the Mammesa Farmer/Livestock Group in Data Village, Duampanua District, Pinrang Regency. This research method uses quantitative with Likert scale measurements. The results of the overall level of motivation in Data Village, Duampanua District, Pinrang Regency, with a total weight of 2,395, which differs between the needs of "Strongly agree" and "Agree", namely between 625 to 3,125. This can be categorized as "Agree" because breeders are aware that raising livestock can increase the opinion and experience of the level of motivation of beef cattle breeders in Data Village, Duampanua District, Pinrang Regency. Obtaining the Agree category in five levels of needs including Physiological needs, security needs, social needs, self-esteem needs, and self-actualization needs. This can be seen from the total weight of 2,395 which shows that raising beef cattle can fulfill physiological needs, the need for security, social needs, the need for self-esteem, and the need for self-actualization.
