The study was designed to explore soil biomass content and soil enzymatic activities that involved in carbon organic soil mineralization. Samples of soil were collected from two locations in Bangka Island. Bulk samples of top soil (TP) and excavated (TG) Â were collected from garden soil in Pangkalpinang. Other soils were gathered from forest floor (TU), beneath pelawan (Tristaniopsis merguensis Griff.) trees which is endemic plant to North Bangka forest. Soil biological character was evaluated by measuring soil microbial population, respiration rate, and cellulase and amylase activities. Experiments were carried out in Research Center for Biology, Indonesian Institute of Sciences, on dried soil treatment (Control), soil moistened with 5 mL H2O in 100g soil (Gluc.0), and soil moistened with 5 mL 1% glucose solution (Gluc.1). Bacterial population obtained was higher than fungal population in all soil samples. Soil respiration activity in TU after treatment was 4.51Â±0.49; 5.26Â±0,79; and 8.28Â±1.41 ppm CO2/100g-soil/5-minutes, respectively. Meanwhile , respiration in TP Â were 3.65 Â± 2.12; 3.57 Â± 1.18; and 7.94 Â± 1.05 ppm CO2/100g-soil/5-minutes; and in the TG are 2.61 Â± 0.70; 3.34 Â± 0.94; and 5.46 Â± 2.30 ppm CO2/100gsoil/5-minutes. Cellulase activity of all samples were not significantly different. Forest soil cellulase activity was significantly different compared to garden soil. Glucose induction was positively increased amylase activity compared to cellulase. Soil enzyme, soil respiration activities and microbial population of forest soil could be used as a reference to recover degraded land in Bangka Island.

PENGARUH SALINITAS DAN INOKULAN BAKTERI TERHADAP PERTUMBUHAN TANAMAN TERUNG (Solanum melongena L.) [The Effect of Salinity and Bacteria Inoculant on The Growth of Eggplant (Solanum melongena L.)] Suliasih, Suliasih; Widawati, Sri

Nitrogen fixing dan phosphate solubilizing bacteria are important PGPR bacterial in addition of plant nutrients by increasing N and P, especially in saline soils. Experiments were conducted to observe the effects of Â soil salinity and bacterial inoculant on growth eggplant (Solanum melongena) at green house of Â Microbiology division, Research Center for Biology, The Indonesian Institute of Sciences, Â Cibinong. Experiment laid out as factorial based randomized complete design Â with three replications. Five levels of watering consisted of (1). Fresh water, (2). NaCl 0.1%, (3). NaCl 1%, (4). Sea water 75 %+25% fresh water, (5). Sea water 100% Â as first factors. Five levels of inoculations/biofertilizers consisted of (1).control without fertilizer (K), (2). NPK (P), (3). Nitrogen Fixing bacteria (BPN1), all treatments was repeated 3 times Â BPN2, mixed inoculation (BPN1 + Â BPN2 + Phosphate Solubilizing Bacteria/BPF) as second factors. Â Results showed that biofertilizer application increased growth and yield of eggplant in various levels of salinity at about 21.56%-53.35% Â compared to uninoculated plants

The spatial dispersal of acid and alkaline phosphates activity in forest soils appears to be controlled by position in the landscape and its soil microbial density. Soil bacteria expressively produced significant level of acid phosphatase in the investigation.The variety of acid phosphatase activity (8.25-37.55 />-nitrophenol.g"soil.h") noted higher and followed by alkaline (0.78-7.15 p-nitrophenol.g-soil.h" ), correspondingly. Acid and alkaline phosphates were exist in both of soil of natural as well as for non-natural forest soil landscape, with the value (po/o=0.6210) of correlation are 0.6889 and 0.6532, respectively. Phosphate Solubilizing Bacteria (PSB) average density in natural forest soil equivalent to 0.61xl0Ã colony forming unit (cfu) and total bacteria is 160xl0 cfu, while the PSB in non-natural forest soil is 7.75xl0 cfu and total bacteria is 48.25x10 cfu. Concerning to the forest environment as soil bacteria inhabitants of PSB, there were significantly difference of PSB population in natural and non-natural landscape forest. Forest environment is negatively affect the soil enzymes activities under Pinus maritima and Caliandra calothyrsus as the lowest activities, and to the highest ones under the Schima wallichii and Eucalyptus saligna vegetation.

BIODIVERSITAS Basidiomycetes DIKECAMATAN KELILA, KABUPATEN JAYAWIJAYA, PROVINSI PAPUA DAN MANFAATNYA SEBAGAI BAHAN MAKANAN DAN OBAT TRADISIONAL Imamuddin, Hartati; Suliasih, Suliasih

Biodiversity of Basidiomycetes was studied in Kelila, Jayawijaya, Papua.The aim of this observation was to identify species diversity of Basidiomycetes and their utilities. Sixty one species were found in the location. The 19 species were edible mushroom while 7 species have been used as traditional medicines and some species have a common odours (smell) and 1 species (Clavatia sp.) contains clavatin which could be used as arm tumour agent.

The biodiversity of nitrogen fixing bacteria (Rhizobium, Azotobacter and Azospirillum) and phosphate solubilizing bacteria in rhizosphere collected from Gunung Halimun National Park were studied.Bacterial population was counted from soil rhizosphere collected from various ecosystem types (determined based on elevation) namely 600 m, 1000 m, 1100 m, 1500 m and 1800 m above sea level.The results showed that the highest population of N-fixing and P solubilizing bacteria at Cikaniki (1100 asl) are founded in the plant rhizosphere of Schima wallichii in plot Suzuki A I and Altingia exelsa in Suzuki A III,at Gunung Botol area is in 1000 m asl,and Ciptarasa area is in 600 m asl.The population of N-fixing and P solubilizing bacteria at Gunung Halimun was influenced by the vegetation type, soil pH,and the elevation of area. Rhizobium, Azotobacter, Azospirillum (N-fixing bacteria); Pseudomonas sp, and Bacillus megaterium (P solubilizing bacteria), are most dominant at 600 m, 1000 m and 1100 m asl.
