Abstract

Amylase enzyme from Endomycopsis fibuligera capable to hidrolize starch into glucose. Insertion of amylase gene from Endomycopsis fibuligera into yeast (Saccharomyces cereviceae) will be able to increase the function of yeast (S.cereviceae) to digest more cheaper substrate, like starch. Before cloning in yeast, recombinant DNA will be made and analyzed in Escherichia coli strain DH5a. The result showed that the sixth transformant consist recombinant DNA that were sensitive to tetracycline medium. Analysis by EcoR1 digestion showed that the size of insertion fragment into Ycp 50 vector are around 0.3 untill 16 kb.

Abstract

The research aimed to discover the response of the fast growing tree legume to Rhizobium inoculation in relation to the population density of soil Rhizobium (indigenous rhizobia). The density of soil Rhizobium bacteria was predicted based on a plant infection test by using the most probable number (MPN) of soil bacteria. The experimental design used in this work was Completely Randomized Design with factorial provided and 4 replicates. The first factor of treatment were inoculation and uninoculation, and the second factor was soil taken from 5 locations in Cigaru and Jampang-Sukabumi villages. The response of the plant was marked by the increase of dry weigh of leaf, root, and number of root nodules. The result of this study showed that the plants planted in the soil media with < bacteria/gram soil showed more response to inoculation than plants planted in soil media with > 40 bacteria/gram soil.

Abstract

An isolation of the leaves of Asteromyrtus sp., Melaleuca leucaleucadendron, M. angustifolia and M. leucadendon Var. latifolia by steam distillation yielded 1.36, 1.02, 1.32 and 0.97 % essential oils respectively. Their constituents were analyzed using two combination techniques, gas chromathography and mass spectroscophy (GCMS). Based on their compositin, the essensial oils of Asteromyrtus sp., Melaleuca leucaleucadendron, M. angustifolia were considered acceptable for commercial essential oil production because of their potential source of cineole (65.11, 60.03. 82.43 % respectively), while M. leucadendon Var. latifolia was a very interesting source of methyleugenol (97.03%) which attractant activity.

Abstract

Timorensis deer (Cervus timorensis) is one of Indonesian natural resources that has economic and aesthetic values. They are widely distributed from Java island to eastern part of Indonesia. Although the deer is protected by law, however interest in rearing by local people is increasing, such as Timor island. Some people has introduced the deer from the vicinity islands in which from the taxonomical point of view could be a separate sub species. There is no data available on the morphological parameters on this deer in Indonesia, nor about the physiological and health status. The present study was aimed to observed the morphological and physiological parameters and its health status of the timorensis deer under captivity. The result showed that at least there is one sub-species which has introduced to Timor island. Mean of the height was less than 70 cm. Mean chewing rate during rumination was 61/minute with the rate of breathing was 24/minute. Rectal temperature was 37.7oC. Internal parasite was considered negligible.

Abstract

An analysis on the chemical constituents of Cinnnamomum macrophyllum Miq leaves from Halmahera island using combination techniques GCMS was conducted. Total numbers of the constituents which can be detected were 59 consisted of monoterpenes, sesquiterpenes, aromatic hydrocarbons, phenol derivates, alkanes, oxygenated hydrocarbon, alcohols, aldehydes, carboxylic acid and alkaloid along with eight unidentified compounds (1-8). Leaves of C. macrophyllum contained bioactive compound such as limonene, isoeugenol, methyleugenon, safrole, vitamin E, furfuraldehyde, 2-furan-carboxaldehyde and 7-methyl xanthine.

Abstract

The behavior study of Java deer (Cervus timorensis) has done for three month in captive breeding study of Java deer (Cervus timorensis) had done for three months in captive breeding at Safari Park Indonesia, Cisarua, Bogor. The object of this study was the daily activities such as: grazing, ruminating, lying and other activities. The method used in this work was Time Sampling. Observations were conducted in six times on daylight and four times in night. The result showed that the average percentage of daily activities of Java deer were 44% for grazing, 27% for ruminating, 18% lying, 6% standing and 5% walking subsequently.
