Abstract

Birds can be used indirectly or directly as a bioindicator of environment. Birds species living in six habitat types of PTInhutani I Labanan Kalimantan Timur (namely, logged-over areas that has been exploited in 1976/1981 and 1981/1986,forested area that is being exploited in 1999/2000, primary forest that will be exploited in 2001/2002, Labanan Jaya Villageinhabited in 1982/1983, and Segah-Malinau Transmigration Settlement inhabited in 1997/1998) were recorded with transectmethod (long of 3 km and within sighting distance of 25-50 m) at 06.30-10.00 and 15.00-17.30 in both dry and rainy seasons. One hundred and two identified species belonging to 34 families and 6 unidentified species were found. Habitat types and seasons affect bird diversity (the number of species and abundance). Percent dissimilarity of birds between habitats ranged 0,53-0,95 in rainy season and 0,54-0,95 in dry season and between seasons ranged 0,50-0,80. Quantitative values have to be completed with qualitative consideration to assess habitat condition or changes.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: bird diversity, forest, urban area, habitat condition.

Abstract

A local strain of Bacillus sp. BAC4, is known to produce penicillin G acylase (PGA) enzyme with relatively high activity. This strain secretes the PGA into the culture medium. However, it has been reported that PGA activity fall and rise during culture, and the activity plummets during storege at –200C, which probably due to usage protease activity of Bacillus sp. BAC4. To study the possible use of Bacillus subtilis 1012M15 as a host cell for cloning the pga gene from Bacillus sp. BAC4, the protease activity of Bacillus subtilis 1012M15 were studied. Protease activity was determined by Horikoshi method. In this experiment, maximum protease activity in Bacillus subtilis 1012M15 culture was obsereved after 8 hours. At this optimum condition, protease activity of Bacillus sp. BAC4 is five time higher than that of Bacillus subtilis 1012M15. This situation promised the possible usage of Bacillus subtilis 1012M15 as a host cell for pga expression. For protease characterization, the bacterial culture had been separated from the cell debris by centrifugation. The filtrate was concentrated by freeze drying, fractionated by ammonium sulphate, dialyzed in selovan tube, and then fractionated by ion exchance chromatography employing DEAE-cellulose. The five peaks resulted indicated the presence of five protease. Based on inhibitor and activator influence analysis, it could be concluded that proteases from Bacillus subtilis 1012M15 contained of serin protease as well as metalloprotease and serin protease mixture.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: protease, penicillin G acylase, cloning, host cell.

Abstract

The coastal area of Baron, Kukup, and Krakal in the southern coast of Yogyakarta is an arid and dried area, and marginalagriculture land. The potential vegetation resources only live on the lands that produce cassava, corn, peanut, and soybean. The increasing benefits of sea products such as fishes still need to be invented. The aims of this research are to inventories and to increase the use of disadvantage resources. This research was conducted from October 1995 to March 1996. The result invents 70 species of useful plants and 21 species of weed that can be used by the people for the needs of their own households. The remainder products of Anona squamosa L., which might easily rot and until now unprofitable, could be used to make some jam. Phylantus emblica L. can be put into a useful product by making them to become candies. Another natural resources that are neglected are the cattle excrement and sharkskin. All kind of sharkskin’s can be manufactured into leather products. While cattle excrement can be produced methane for cooking and lighting. There are 163 species of ornamental fishes in Kukup, and 20 species of consumed fishes in Baron. In search of ornamental fishes, the fishermen have a bad-habit of using hazardous materials such as potassium cyanide. Besides endangers the reef communities, algae and fish-larvae, it makes the ornamental fishes they caught unhealthy and cannot be exported since their lifespan is very short. Due to this factor, ornamental fishes are only available in the local market of Kukup.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: natural resources, waste, coast, Baron, Kukup, Krakal, Yogyakarta

Abstract

Mangrove ecosystem is a specific ecosystem that only take about 2% of total land in the earth. Indonesian mangroveecosystem is the widest in the world and as a center of distributioan and ecosystem biodiversity, however it undergoesrapid and dramatic destruction. In just 11 years, between 1982-1993, more than 50% of Indonesian mangrove disappeared. The most factor threatening the mangrove ecosystem is human activities, including convertion to aquaculture, deforestation, and environmental pollution. Other factors such as reclamation, sedimentation, and natural disturbance are also contributed to the disappearance of the mangrove. Mangrove ecosystem is very important in term of socio-economic and ecology functions. Because of its functions, wide range of people alaways paid attention whenever mangrove restoration taken place. Mangrove restoration potentially increases mangrove resource value, protect the coastal area from destruction, conserve biodiversity, fish production and both of directly and indirectly support the life of surrounding people.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: mangrove, restoration, management, Java.

Abstract

The objectives of the research were to detect genetic variations on ND-5 region of mtDNA of Benggala and Madura cattles, and to compare the genetic diversity within or between Madura and Benggala cattle. Genetic variations and its effects on phenotype characters have been studied largely in dairy cattles, but not for beef cattles, especially for Indonesian local cattles. PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) was used to detect polymorphism on ND-5 region of mitochondrial DNA. Polymorphisms were found on ND-5 mitochondrial DNA fragment using HindIII restriction enzyme. This variation were likely due to lost of HindIII restriction site on ND-5 mithocondrial DNA fragment.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: ND-5 mitochondrial DNA, genetic variation, PCR-RFLP.

Abstract

The objectives of the research were to detect DNA polymorphism at locus 2 of bovine growth hormone gene of Madura cattle and to know its genetic diversity. DNA polymorphisms and their effect on phenotypic traits have been studied widely in dairy cattle but not for beef cattle, especially for Indonesian local cattle. Polymorphism was detected using PCR-RFLP using primer GH-5 and GH-6 for amplifying locus 2 of growth hormone gene. Genetic diversity was analyzed based on the formula of Nei (1973, 1975). DNA polymorphism was found on locus 2 of growth hormone gene using MspI restriction enzyme. This polymorphism may be caused the lost of restriction MspI site. The genetic diversity was 0.4422.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: bovine growth hormon gene, PCR-RFLP, polymorphism, Msp I restriction enzyme, Madura Cattle.
