Abstract

Acute respiratory infection is a serious health problem in the world and in Indonesia. Acute respiratory infection is caused by a variant of the bacteria and resistance to antibiotics. The Latest researches on antibacterial compounds based on natural ingredients have been conducted. One of them is derived from green algae. This study aims to determine the antibacterial activity of green algae Caulerpa racemosa extract in inhibiting the growth of pathogenic bacteria causing acute respiratory infection. This study includes an extraction process using chloroform. Antibacterial testing was done by using a concentration of 0.5%, 1%, 5%, 10%, 20%, 40%, 60% and 80%, in order to obtain the minimal Inhibitory Concentration. The results showed that C. racemosa extract was able to inhibit the growth of test bacteria Streptococcus mitis, Bacillus anthrachis, and B. cereus, with the best activity at  concentration of 0.5% and 80%. Meanwhile the extract did not have the activity to inhibit the Gram-negative bacteria. Phytochemical test showed that chloroform of C. racemosa extract contain steroids and terpenoids compounds capable of inhibiting the growth of testing bacteria. Key words: antibacterial activity, C. racemosa, pathogenic bacteria, Acute respiratory infection

Abstract

Fungi has several role for humankind, one of them is as food. The potency of wild edible mushrooms as a source of nutrition still need to be explored to support national food security. The aim of this study was to determine the composition of nutrient content of wild edible mushroom called Tambir that commonly be consumed as alternative food by local people in Jayapura, Papua. Samples were collected from the traditional market nearby Uncen campus in Waena, Jayapura, Papua. Micro Kjeldahl method was used to analyze the crude protein content, hexane-gravimetry for lipid, spectrophotometry for carbohydrate, and high performance liquid chromatography (HPLC) for amino acid composition. The results showed that this mushroom has 15.74 % crude protein, 2.59 % lipid, 50.17 % carbohydrate and 8 essential amino acids. The chemical value of those eight essential amino acids were more than 100 that means this mushroom has no amino acid limitation. Therefore, Tambir could be a good alternative protein source for local people. Key words: fungi, proteins, local knowledge, Tambir, Papua.

Abstract

Fusan FP4 is one type fused materials derived from intraspecific fusion of Pichia manshurca. The fused materials have superior capabilities compared with other materials, especially in producing inulinase enzyme (E.C. 3.2.1.7). The aims of the study are to determine the production of the enzyme inulinase of fusan FP4 and the growth profile formed. Growth can be detected by the addition of size and cell division. Growth measurements of fusan FP4 was carried out for 24 hours and observation and sampling was done every 6 hours for 24 hours. Observations of growth are conducted qualitatively by using a spectrophotometer, while the production of inulinase done using DNS method. The results of this study showed that the highest inulinase production was 1.948 U/ml and occurred at log phase with 6 hours of incubation time (t6) to 12 hours (t12). Key words: inulinase, Fusan FP4, log phase, P. manshurca.

Abstract

Daun gatal (Laportea aestuans) is an indigenous plant of Papua hich has been widely used for pain relief as traditional medication in the local community. The leaves were just picked then treated to cure for painful body. This treatment are giving itchy sense as an indication that medication is working on the body as local people assumed. The aim of the study was to determine the activity of antibacteria of daun gatal against Escherichia coli, Staphylococcus aureus and Salmonella typhi. Samples of daun gatal were collected from Biak Numfor Papua. The methods are started with filtering of daun gatal using 100 mash and extracted with ethanol. Extract was made in 250, 500, 750, 1000 ppm, with chloramphenicol as a control positive, while the test of antibacterial activity was done by disc diffusion method. The results showed that daun gatal has antibacterial activity against E. coli, S. aureus and S. typhi. Daun gatal extract (L. aestuans) is effective in inhibiting the growth of bacterias with zone inhibition of 1000 ppm extracts which were 8.55 mm (E. coli), 9.02 mm (S. typhi), dan 9.37 mm (S. aureus). Key words: Antibacteria, E. coli, L. aestuans, S. aureus and S. typhi.

Abstract

Sowang (Xanthostemon novaguineense Valet.) is an endemic plant of Cycloops and strictly distributed. Since years, the population of the plants is threatened by human activities through land conversion, forest burning and logging. There are only few seedling grow in Cycloops naturally. Sowang wood is known as a good quality, because of its inherent hardness and high density. Scienfific information about this species is remain unclear. Regarding the plant regeneration, it is also not enough information so far. The study was conducted at three places around Cycloops areas namely Waena, Doyo Baru (sowing habitat) dan Wambena (no sowang areas) of Jayapura Regency, Papua and also greenhouse of FMIPA Cenderawasih University. The experimental units were set up in a completely randomized design with 3 treatments. Each experiment was carried out in three replicated and each replicate includes 100 seeds. Data were analyzed by analysis of variance (ANOVA), followed by LSD α=0.05. The result showed that there is no relation between geographical distribution of Sowang at Cycloops and the phisical and chemical soil. All type of soil used in this study was good as media of the seed germination. Regarding the ratio of the sapling population, the germination is still low only 18%, the seedling only survive for 38 days after sowing. Key words: Cycloops, regeneration, Sowang, Papua.

Abstract

Nyalik tribe community in Silimo District Yahukimo Regency Papua have traditional knowledge about the sweet potato (Ipomoea batatas (L.) Lam.) applied it in the cultivation. Traditional knowledge is knowledge of local community in an area that a culture tradition handed down from generation to generation. Traditional knowledge about the sweet potato is a wealth of local wisdom in Papua, which need to be investigated, developeds, utilized and conserved the types of sweet potatoes which is quite much and widely spread in Papua. It is important to support local food diversification program and to improve national food security. The method of the research is descriptive qualitative method by doing observation. Data was obtained from the original source of the sweet potato farmer as respondent by using questionnaire and also measurement and documentation in the field. The result showed that Nyalik tribe people have recognized, identified and cultivated 33 types of sweet potatoes and grouped them according to their used into 5 groups: as for baby food or children, adult food, sick person, traditional ceremonies and animal feed. Nyalik tribe community has a traditional knowledge about the sweet potato and cultivation system and also how to overcome the obstacles in sweet potato cultivation. Keywords: Traditional knowledge, I. batatas, Nyalik tribe, Silimo, Yahukimo
