Gayo women in Bener Meriah Regency are one of the communities that still maintain the use of plants as cosmetics, one of which is used as hair care. Each ethnic group has its own way of using plants according to local wisdom, but it’s knowledge is only passed down orally from generation to generation without any written documentation. This research aims to find out about the species of plants used as hair care by Gayo women in Bener Meriah. This research uses an exploratory survey method. Sample determination was carried out using snaw ball sampling. The sample includes housewives and youth from the Gayo tribe, as well as people who use plants as hair care. The data was analyzed descriptively qualitatively and the data was displayed in the form of tables and figures. The results of the research show that there are 11 plant species used in Gayo women's hair care.

Ferns or Pteridophyta are lower plants from the Cryptogamae division, which can be distinguished between roots, leaves, and stems. Ferns have great ecological importance, namely as understory plants that contribute to the long-term sustainability of forest ecosystems by mixing soil litter, as ground cover vegetation, as producers in the food chain, and as one of the pioneer plants in the succession of forest ecosystems. This study aims to determine the species, diversity index, and distribution pattern of ferns based on different vegetation in the Forest Area of Bukum Village, Sibolangit District, North Sumatra. The method used in this research is an exploratory survey method with a purposive sampling technique. The results of this study were 39 species found in the Forest Area of Bukum Village, 21 species in the watershed vegetation, 16 species in the Coffee Garden vegetation, and 14 species in the Primary Forest vegetation. The diversity index in the watershed vegetation is 2.32, the coffee plantation is 2.02, and the primary forest is 1.86. Based on the results of the diversity index, it shows that the diversity of ferns in the Forest area of Bukum Village is classified as moderate so the community is said to be stable. The Morisita index on the river flow vegetation is 1.43, the coffee garden vegetation is 2.13, and the primary forest vegetation is 2.05. The results of the Morisita index from each vegetation indicate that the distribution pattern of ferns in the Forest Area of Bukum Village is grouped because the environmental conditions required by ferns are not uniform.

Diarrhea that occurs in the digestive tract is a big problem for human intestinal health. This can be caused by the activity of pathogenic bacteria in the form of Vibrio cholera and Shigella dysinteriae. In this study, kombucha has been shown to have pharmacological activity in vitro in inhibiting the growth of Vibrio cholera and Shigella dysinteriae bacteria at all sugar concentrations. The purpose of this study was to determine the in vitro pharmacological activity of the butterfly pea flower kombucha in inhibiting the growth of the two test bacteria consisting of a sugar concentration of 20%, 30% and 40%. The method for testing the inhibition of both bacterial growth tests is disc diffusion. One way ANOVA and post hoc analysis are one of the quantitative test methods used in this study of the average diameter of the inhibition zone of teal flower kombucha from various sugar concentrations. The results of this study have proven based on a one-way ANOVA with each P value> 0.05 and then continued through post hoc analysis concluded that the telang flower kombucha at a concentration of 40% is the best treatment in inhibiting the growth of both test bacteria where the concentration is significantly different from sugar concentration 20% and 30%.

Kidneys are organs that have the potential for damage caused by toxic substances. The use of paracetamol in high doses or long-term therapeutic doses can cause adverse effects in the form of damage to the kidneys. Plants that have the potential to become medicinal raw materials against kidney damage are Annona muricata L. The purpose of this study was to determine the potential protection of ethanolic extract of soursop bark (EESB) against histopathological rat kidney induced by toxic doses of paracetamol. This study used an experimental method using a completely randomized design (CRD). The normal control group (K0) and negative control (K-) were given distilled water, while in the treatment group the doses of EESB were 150, 300 and 600 mg/kgBW dissolved in 1 ml of distilled water for 14 days. On the 7th day, all groups of rats were given paracetamol at a dose of 1350 mg/kgBW except for the K0 group. Each group was 5 repetitions, so that in this study used 25 rats (Rattus norvegicus L.). Samples of kidney organs were taken on the 14th day to observe the histopathological structure of the tubular cells undergoing necrosis. The results showed that at a dose of 300 mg/kgBW EESB had the potential for protection against kidney histopathology by suppressing the occurrence of cell death (necrosis).Keywords: Soursop bark, kidney, paracetamol, necrosis

The primary carrier of the dengue virus-caused disease dengue hemorrhagic fever is the Aedes aegypti mosquito.By eliminating the flick using larvacides, the effort of seeding can be avoided. Tannin concentration in lime leaf extract ( Citrus aurantifolia ) is known to suppress the growth of larval cuticles. The objective of the study was to assess how C.aurantifolia lime leaf extract affected the development of Ae. aegypti larvae. This form of research is experimental, and this extract is produced by macerating lime leaves in 90% ethanol before extracting it via evaporation. The study included four groups: aquades used as a negative control for testing on larvae and concentrations of 12.5%, 25%, and 50% lime leaf extract. Testing and observations have been conducted for 24 hours. The findings showed that different concentrations of lime leaf ethanol extract ( C. aurantifolia ), which is 100% poisonous to Ae. aegypti larvae, can impede its growth. To conclude, biolarvasida can be created by using the lime leaf extract. No morphological modifications were made to the Ae. aegypti larvae used in this investigation.

Tannin concentration in lime leaf extract ( Citrus aurantifolia ) is known to suppress the growth of larval cuticles. The objective of the study was to assess how C.aurantifolia lime leaf extract affected the development of Ae. aegypti larvae. This form of research is experimental, and this extract is produced by macerating lime leaves in 90% ethanol before extracting it via evaporation. The study included four groups: aquades used as a negative control for testing on larvae and concentrations of 12.5%, 25%, and 50% lime leaf extract. Testing and observations have been conducted for 24 hours. The findings showed that different concentrations of lime leaf ethanol extract ( C. aurantifolia ), which is 100% poisonous to Ae. aegypti larvae, can impede its growth. To conclude, biolarvasida can be created by using the lime leaf extract.

The study was conducted to determine species diversity, species evenness, and relative abundance of butterfly species in the Forest of Bukum Village Sibolangit District Deli Serdang Regency North Sumatra. This research is an exploratory survey using the roaming method and the VES method. Sampling using insect nets, in the morning at 08.00-10.00 WIB and in the afternoon 14.00-16.00 WIB. There are 39 species of butterflies from 6 families with 473 individuals. The butterfly species diversity index in the Forest of Bukum Village has an average value of 2.93 which is included in the medium category. The evenness index of butterfly species in the Forest of Bukum Village has an average value of 0.79 which is included in the high category. The relative abundance index of butterfly species in the Forest of Bukum Village is the Ypthima baldus butterfly species with an average abundance value of 18.60%. Based on the analysis of the diversity index, evenness index, and relative abundance index of species, it shows that abiotic factors or environmental conditions in the Forest of Bukum Village are in accordance with the life cycle of the butterfly.
