Abstract

The high exposure to free radicals and glucose blood levels in diabetes potentially damage the body cells and decrease body immune status that is shown by changes in the number of blood cells that can cause complications. The purpose of this research was to study the effect of ethanol extracts of jeruju (holy mangrove) leaves (Acanthus ilicifolius L.) and taurine on hematopoiesis profile by measuring the number of erythrocytes, the number of leukocytes and the leukocytes differential. This research used a Completely Randomized Design (CRD) by 5 treatments with 5 repetitions conducted for 14 days. The treatment groups were: K1 negative control, K2 positive control (alloxan induced only), P1 induced by alloxan and given 100% ethanol extract of jeruju leaves at dose of 22.4 mg/bb/day, P2 induced by alloxan and given 50% ethanol extract of jeruju leaves dose of 22.4 mg/bb/day, and P3 induced by alloxan and given taurine dose of 15.6 mg/bb/day. Data were analyzed by ANOVA and followed by LSD test at the 5% level. The results showed that the administration of jeruju and taurin can maintain the number of leukocytes and the number of lymphocyte cells that were close to normal after induced by alloxan. But has no effect in the number of erythrocytes in mice

Abstract

Birds are one of the most diverse animals in the world, especially in Indonesia. Liwa Botanical Garden located in Pekon Kubu Perahu, Balik Bukit District, West Lampung Regency, is a conservation area with the theme of conservation and development of ornamental plants, representing the flora of Southern Sumatra. This research is a continuation of the collaboration between the Department of Biology and Balitbang UPTD Liwa Botanical Garden, West Lampung Regency. The presence of birds in the Liwa Botanical Garden is also a bioindicator of biodiversity for the environment in this area. By maintaining the presence of birds in the Liwa Botanical Garden means protecting their habitat and existing plants. The purpose of this study was to determine the species of birds based on the height of the perched trees in the Liwa Botanical Garden and the abundance of their species. The method used in this research is the point count with the observation time for 9 days in the morning and evening at the height of the tree in 3 different observation stations. Birds on KRL are mostly found on perches at an altitude of 2 - 7 meters, in the category of shrubs and trees, there are 19 out of 25 bird species found. The highest Relative Abundance Index (IKR) was Collocalia esculenta at 39.91% and the lowest IKR value was 7 bird species, each with 0.14% value. The conservation status of the 25 bird species based on IUCN is Least Concern (LC) and based on CITES there is one species that is included in Appendix II, namely Ictinaetus malayensis while based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia No. P.20 / MENLHK / SETJEN / KUM.1 / 6/2018 there is one bird species that is included in the protection, namely species Ictinaetus malayensis
