Abstract - In Lembak delapan Tribes traditional medicine, water decoction of the Sungkai leaves is used for raw material fever-lowering drugs (antipyretics), to maintain good health, and for malaria drug. This study aims to test the effectiveness of the infusion of leaves P. canescens to maintain goodhelth (immunity) in mice (Mus muculus). The Young leaves of Sungkai (P.canensces) was extracted by maceration method using 96% alcohol solvent. This study used 25 male mice strain Swiss Webster with 7-8 weeks old, with a body weight ranging from 30 g. At the immunity test, mice were divided into 5 groups. Group 1 (negative control) were given distilled water, group 2 (positive control) was given imunos 0.07 mg / kg bw, for the three treatment groups were given of the extract dose of 0.186 mg Sungkai / Kg mm, 0.375 mg / kg bw, and 0, 5625 mg / kg bw. Treatment with one gavage, with a span of 24 hours. After the calculation is done by taking a blood leukocytes from mice tail. Data were analyzed using ANOVA tables and followed by LSD test. The results showed that  the Immunity test dose of the most effective in helping the immune system with a dose of 0.567 mg Sungkai extract / kg bw, tends to increase by 36% leukocytes, better than than the comparator dose (imunos) leukosit only increase the amount by 23%.  Keywords: sungkai,immunity, mice

Abstract

Amorphophallus titanum is an endemic flora of Sumatra that was listed in the IUCN Red List in 2018 under the endangered category. Conservation efforts must be undertaken to preserve A. titanum both ex situ and in situ. Additionally, artificial propagation of plants needs to be carried out to obtain seedlings that can be replanted in their natural habitat or conservation areas. Propagation through the rachis cutting method is interesting to conduct because it is considered easier and more cost-effective compared to other methods. This research aims to determine the potential success of the planting media used and the challenges faced in the propagation of A. titanum through the rachis cutting method, conducted at the Pondok Sains Terpadu (POSTER) conservation, Science Education Study Program, Faculty of Teacher Training and Education, University of Bengkulu. The planting media used were cocopeat and soil, with 40 samples of A. titanum rachis and 20 repetitions for each planting medium. The research results show that the cocopeat medium produced a higher success rate (15%) than the soil medium (0%). Callus appeared in the 8th week, followed by buds in the 12th week. The leaves experienced decay and drying in the 16th week, but the buds continued to grow until they bloomed perfectly in the 20th week. The failure of rachis cutting propagation using average soil media was observed from the 4th week after planting. Thus, it can be concluded that cocopeat media shows potential to support the propagation efforts of A. titanum through the rachis cutting method. The challenges of this research are influenced by pest and disease disturbances (S. rolfsii, Collembola, and H. haydeniana) due to the open research location, as well as environmental factors such as temperature, humidity, light, and pH of the growing medium.
