Abstract

This study aims to determine how to identify the types of secondary metabolite compounds contained in durian leaves. The study was conducted by an experimental method by identifying secondary metabolite compounds on durian leaves using phytochemical screening. The sample criteria used were the leaf buds and all the leaf strands (except the leaf bones). The results of the study showed that of the three types of durian leaves namely copper, baskets and Sp A. There are several types of secondary metabolite compounds including alkaloids, steroids, and terpenoids. Phytochemical screening analysis was carried out using thin layer chromatography by showing RF values on three types of durian leaves using methanol and ethyl acetate solvents in a ratio of 3: 1. RF value on copper durian is 0.97, bakul durian is 0.95 and Sp durian. A 0.94.

Abstract

Natural Park (TWA) Sicike-Cike is highland tropical  rain forest  located in  Kabupaten  Dairi,  North Sumatera. The park is home of various ferns. The purpose of this research is to inventory fern’s species classified as Selaginellaceae, in the above Park. Samples were obtained using “purposive sampling’(descriptive method) by exploration technique, there were 5 Specias identified; Selaginella intermedia, Selaginella longiaristata, Selaginella ornata, Selaginella plana, and Selaginella willdenowii.

Abstract

Research on Types of Anura in Deleng Ketaruman, Bukum Village, Subdistrict Sibolangit, Deli Serdang Regency, North Sumatera Province was conducted in February 2018. This study aims to obtain and document the types of Anura, and environmental parameters found Anura in Deleng Ketaruman, Bukum Village, Subdistrict Sibolangit, Deli Serdang Regency, North Sumatera Utara Province. The method used in this research is Visual Encounter Survey. The equipment used in this research were headlamp, background black, battery, camera, temperature and temperature gauge, plastic, frog capture net, amphibious identification book. Observation of the types of Anura was done during night. Anuras were observed only along the tracking path. The results showed that 9 species consisted of 6 families found along the tracking tracks one species of Bufonidae family (Phrynoidis juxtaspera), three species of Dicroglossidae family (Fejervarya cancrivora, F. limnocharis, Limnonectes blythii), one species of Megophrydae family (Megophrys paralella), one species of Microhylidae family (Microhyla superciliaris), two species Ranidae family (Hylarana chalconota, H. erythraea), and one species of Rhacophoridae family (Polypedates leucomystax). The ambient temperature of the Anura species ranges from 22ºC-24ºC to grassland habitats, puddles, litter and ponds.

Abstract

Manilkara zapota L was included plant which the most popular in South East of Asian. The society also used young fruit, bark, and Sapilla Manila Leaf as tradisional medicine diaerrhea resistant, because substance of tanin was contained in it could hampered and killed the number of bacterias such as Shigella, Salmonella thypii, Escherichia coli. This research purposed for knowing ability of blocked energy from exstract Sapilla Manila Leaf towards Escherichia coli. This research experimentalsm with used qualitatif methode and diffusion methode. Concentration extract of  Sapilla Manila Leaf which was used namely 5%, 10%, 15%, 20% with 5 times,. The result of research showed that extract Sapilla Manila Leaf with each that concentrat have not hampered growth of Escherichia coli. The possibility was caused by several factors such as the concentration level of the extract, the nature of the bacteria used and the tools used in the solvent evaporation process.
