Abstract

The physiological character, especially the effect of pH and organic substrate on the growth and activity of some ammoniaoxidizing bacteria was carried out. The results show that eight out of twenty isolates have ability to reduce ammonium, two of them i.e. isolate AOB1 and AOB2 could reduce more than 90% of ammonium. The growth and activity to reduce ammonium to nitrite was attained optimum at pH 7-8. From the result also indicated that the growth and activity of both isolate AOB1 and AOB2 were higher on the organic carbon (acetate)-containing media. This finding indicated that both of isolate AOB1 and AOB2 were heterotrophic ammonia-oxidizing bacteria.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeywords: organic substrate, acetate, ammonia-oxidizing bacteria, ammonium, nitrite.

Abstract

Agricultural wastes, such as coconut meal and kernel palm meal can be used to fulfill the need of feed for ruminants ormonogastrics. Fermentation technology using Aspergillus niger has been reported allow to increase their nutritive value.Isolation of the asporogenous strain which could spored at room temperature but could not spored at 37oC is expected to sole the fermentation of spores in the fermentation product. The spore formation of mutants at the fourth day incubationtime (10%) was less than the wild type (100%). The variance analysis of protein content in vitro Dry Matter Digestibility (IVDMD) and in vitro Protein Digestibility (IVPD) showed that the kind of mutants were interacted with the incubation time(P<0,01). The highest protein content of coconut meal was obtained from E27 mutant (33.0%), kernel palm meal wasobtained from E14 mutant (31.4%) at the fourth day of incubation time. The highest IVDMD of coconut meal (62.1%), kernel palms meal (61.8%) at the fourth day incubation time and from all E27 mutant. The highest IVPD of coconut meal was obtained from E27 mutant (20.49%) at the fourth day incubation time, kernel palm meal was obtained from E27 mutant (18.66%) at the fourth days incubation time.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeywords: mutant Aspergillus niger, coconut meal, kernel palm meal, fermentation

Abstract

The selection of appropriate rattan for a certain use must be based on adequate information about its potency, anatomicalstructure, and chemical properties. Standards methods of inventory development by Curtis method was used to obtain data on its density and frequency. To know the anatomical structure of preparation were made according to Schultze method and microtome preparation according to Staining Paraffin Section with Safranin. While to know the chemical component of rattan stem the analyzed by Standard Industry Indonesia procedures. Calamus occidentalis is one among other Java rattan species which its distribution is limited in the area of Ujung Kulon National Park, West Java. C. occidentalis may be utilized for various purposes based on the following characteristics: species density of 21 cane/ha; and anatomical structure: fiber length of 2204 μm, fiber-wall thickness of 4.26 μm, vascular bundle diameter of 812.5 μm, metaxylem diameter of 293.75 μm, proxylem diameter of 43.5 μm, and phloem diameter of 37.5 μm. Its chemical components are cellulose (49.95%), lignin (22.39%), and air-dry moisture (12.27%). Based on the above information, C. occidentalis rattan species possibly can be used as an alternative substitute of Calamus manan, an endangered rattan species, because several properties of C. occidentalis has similar with that of C. manan.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeywords: commercial-value, possible utilization, Calamus occidentalis

Abstract

Dipterocarpaceae is one of the biggest family with >500 species in the world, and most of dipterocarps population aregrown in Indonesia which have high economical value of wood. One of the most important value from dipterocarps species is high on endemicities; there are up to 128 species (53.78%) from 238 dipterocarps species in Indonesia. Distribution of dipterocarps species would be affected by some factors especially edaphic, climate, and altitude. In Indonesia the dipterocarps species distribution could be shown from islands groups, number of species and forest types. Based on the observation of herbarium collection in Herbarium Bogoriense the distribution of the most dipterocarps species was in the altitude of 0-500 m and 500-1000 m on the dipterocarps forest type. Kalimantan and Sumatra were the two bigger islands with have the dipterocarps species distributed relatively high on population and species.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeywords: Dipterocarpaceae, ecological distribution, altitude, Indonesia.

Abstract

Acacia nilotica (L.) Del. is a thorny wattle native in India, Pakistan and much of Africa. This acacia is widely distributed in tropical and subtropical Africa from Agypt and Mauritania to South Africa. In Africa and the Indian Subcontinent, Acacianilotica is extensively used as browse, timber and fire-wood species. The bark and seeds are used as source of tannins.The species is olso used for medicinal purposes. Bark of Acacia nilotica has been used for treathing haemorrhages, colds, diarrhoea, tuberculosis and leprosy; while the roots have been used as an aphrodisiac and the flowers for treathing syphillis lessions. The invasion of Acacia nilotica has resulted in the reduction of savanna in Baluran National Park reaching about 50%. Pressure to the savanna has a great impact on the balance and preservation of whole ecosystem in Baluran.© 2004 Jurusan Biologi FMIPA UNS SurakartaKey words: Acacia nilotica, biology, ecology, grassland, Baluran National Park.
