Abstract

Wawonii Island is belonging to Province of South-east Sulawesi, which covers area of about 650 km2. The areas is divided into four forest zones that were protected forests, production forests, limited production forests and social forests. This island was selected as a study site with consideration that this island estimated to have unique flora as same as to Sulawesi Island in general. In addition, so far there is no information about flora in this area. The study was conducted by exploring where the forest area visited, in order to collected and inventoried of plant with special attention to orchid species. Out of this study there are about 80 species of orchid were recorded and three species of them were Anoectochilus cetaceus Bl., Cryptostylis javanica J.J. Sm. and Malaxis koordersii (J.J. Sm.) Bakh. f., identified as new record from Wawonii Island. Those three species according to previous information were admitted as endemic of Java. Although morphologically those three species collected from Wawonii were little bit different to which occurred in Java, but based on the species character they unable to be considered as different species. Consequently since those three the species found in Wawonii Island, those species should be categorized as non endemic of Java.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Orchid, new record, Wawonii Island.

Abstract

Mahkota dewa (Phaleria macrocarpa [Scheff.] Boerl.) is a poisonous plant, but almost all parts of the plants can be used as a traditional medicine. Consuming the plant directly can cause swollen, sprue, numb at tongue, fever, even unconscious. Although the plant can conquere various diseases, from diabetes mellitus, hemorrhoid, impotency to cancer, but research on the plant is still limited. A researchwas conducted to find out antioxidant activities at a parts of mahkota dewa plant by free radical scavenging method (DPPH). The highest activities of the parts of plant are young fruits and old fruits in the ethanol and methanol solvents. Then after partitioned based on the polarity (ethylacetate, n-buthanol and water) showed that n-buthanol extract of young fruits gave inhibition value IC50 = 41,07 ppm.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Mahkota dewa, P. macrocarpa, plant extracts, antioxidant, DPPH

Abstract

Malaria remains as one of global health problem, in which malaria infection in the last two decades increase twice. On the other hand, the uses of plants as antimalarial sources had been known. Some plant species of Simaroubaceae have been known to have antimalarial properties. Picrasma javanica is one plant species of Simaroubaceae. In this study, P. javanica extracts was tested for antimalarial against rodent plasmodium, Plasmodium berghei in single dose (20 mg/kg BW). Leaves, fruit and stem bark extracts of P. javanica were tested to determine the extract which has the best in decreasing parasitemia, followed by variation doses test (1, 10, 100 and 1000 ppm) to determine the effectivity dose (ED50). The results showed that stem bark extract decrease parasitemia (73.89%) better than leaves (71.4%), fruit (-) extracts and chloroquin (32.35%) as positive control. The effective dose (ED50) of stem bark extract was 110.09 mg/kgBW. Phytochemical screening showed that stem bark extract of ki pahit (P. javanica) contained alkaloid, flavonoid, tannin and diterpene.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Picrasma javanica, Plasmodium berghei, ED50

Abstract

Diversity and vertical distributions of scarabaeids dungbeetles (Coleoptera: Scarabaeidae) were studied in a tropical mountaineous rainforest of Gede Pangrango National Park using dung traps. Samples were collected at four altitudes of 500-1000m, 1001-1500, 1501- 2000, and 2001-2500m of five different collection sites (Cibodas, Selabintana, Situ Gunung, Bodogol, and Gunung Putri). 1052 individuals of 28 species of scarabaeid dungbeetles that belongs to five genus were collected. The most diverse groub was the genus Onthophagus, which consists of 21 species (75% of collected species) and followed by Copris with 3 species (10.7%), Paragymnopleurus with 2 species (7.1%), Catarsius with 1 species (3.6%), and Phacosoma with 1 species (3.6%). The Shanon-Winner index of diversity and evenness were gradually declining during the time when altitudes were increasing. Altitude was an important factor in the diversity, abundance, and distribution of dungbeetles. The diversity of dungbeetles at the interval of 1001-1500m and 1501-2000m were not so high but abundance and similarity were high. Diversity index, evenness, abundance, and species similarity of dungbeetles at the interval of 2001-2500m was low because of unfavourable habitat. Although the diversity of dungbeetles at the interval 500-1000m was the highest, however abundance and similarity index were relatively low. Analyse of diversity, abundance, evenness, and similarity of dungbeetles on each of the different altitudes and environment conditions were discussed in this paper.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: diversity, vertical distributions, scarabaeid dungbeetles, Gede Pangrango National Park, Wawonii Island.

Abstract

Every species of soil macrofauna prefer specific food and environment to be establish in it's habitat. Their diversity depend on variation of food and environmental condition. The aim of this research was to study the effect of different crop residue and light intensity on population of several soil macrofauna specieses. Mycrocosmos experiment was arranged in split-plot design with two treatments factor, i.e.: (1) crop residue (albizia, papaya, elephant grass, maize, sweet potato and without crop residue input), and (2) light intensities (0, 5, 15 and 25) Watt/day. The soil macrofauna were earthworms, millipedes, scarabids larvae and cocroachs.Results of the study showed that: (1) crop residues apllication increased soil macrofauna population, especially maize residue ( by 113%, respectively, compare to control tretment), (2) on higher light intensity, population of earthworms, scarabids larvae and cocroach decreased, but population of millipedes increased, (3) the highest macrofauna population was on maize residue and 5 Watt/day light intensity treatment.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Soil macrofauna, preferency, crop residue, light intensity

Abstract

Production of β-glucan by Agrobacterium sp is influenced by the composition of nutrition in the fermentation media. Molases has been used successfully by others in the fermentation media of S. cerevisiae to increase the yield of -glucan, and similarly, uracil has been used in the fermentation media of Agrobacterium sp to increase the yield of -glucan. Investigations to increase the yield of -glucan by two strains of Agrobacterium sp, i.e. A1.5 (reference) and B4.4 (local strain), have been carried out by addition of various combination of molases and uracil into fermentation media, i.e. 5%(v/v) molase-0,05%(b/v) uracil; 5% molase-0,025% uracil; 10% molase-0,05% uracil; and 10%molase-0,025% uracil. The β-1,3-glucan and β-1,2-glucan fractions were separated by extraction method. Beta-glucan concentration was determined as the glucose monomer using the phenol-sulphate spectrophotometric method at 490 nm. The protein content was determined by a modified Lowry-spectrophotometric method at 750 nm. The results showed that all combination of molases and uracil in the fermentation media of Agrobacterium sp A1.5 and B4.4 strains have increased both the dry-weight yield of β-glucan (crude) and the β- glucan content, with the highest was in a medium containing 10% molases-0,025% uracil combination. In the above medium, the A1.5 strain produced the highest β-glucan (7,5%) with the lowest protein content ( 8,4%) in the β-1,3-glucan fraction, while the β-glucan content in the β-1,2-glucan fraction were all lower than in the control media, while the protein content were all higher than in the control media. Inthe above media, the B4.4 strain produced the highest β-glucan, 7,2% in the β-1,3-glucan fraction, and 13,1% in β-1,2-glucan fraction, while the lowest protein content ( 8,4%) was in the β-1,3-glucan fraction. In conclusion, fermentation media of Agrobacterium sp A1.5 strain or B4.4 strain containing molase and uracil combination have increased both the dry-weight yield of total β-glucan (crude) and the β-glucancontent, while reduced the protein content. There is no clear FTIR spectrum difference between supposedly β-1,2-glucan fraction and β- 1,3-glucan fraction.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Beta glucan, Agrobacterium sp., Molases, Uracil
