Abstract

Bawean deer (Axis kuhlii) is endemic to Bawean island with its status under IUCN record as RARE. Information on the calving pattern in nonexistence and there is a need to understand more on their reproduction physiology for conservation purposes. Record on the calving from Bawean Deer and others tropical deer (Cervus timorensis and Cervus unicolor) from Surabaya zoo were compared. The data were obtained from 1989 to 1996 calving time. The result showed that the mean calving date for Bawean deer is July 14th (SE = 8.3 days, n = 130), Timorensis deer being may 25th (SE = 11.0 days, n = 74), and Sambar deer being Juny 16th (SE = 26.2 days, n = 13). The calving time Bawean deer are spread equally between months, whereas Timorensis and Sambar deer tended to have a peak calving time with Timorensis Deer in July. Due to a small of calving record in Sambar deer, no conclusive result can be gathered.

Abstract

The extra cellular product (ECP) was rapidly induced leucocyte number compared to Edwardseilla tarda NUF251 in eel blood. The reason could be live cells need time to multiplied in eel body whereas the ECP composed of high protein therefore induce the leucocyte production in short time. The number of leucocyte in eel blood were not different between inactivated ECP and control eels. Although the leucocyte number increased gradually in live cells injected eel but have not correlation to increasing phagocytosis index (PI) in vivo phagocytosis. The PI and phagocytic rate (PR) of in vivo phagocytosis relatively constant from 24-96 h post injection.

Abstract

Experiment on salinity tolerance in Macrobrachium sintangense was conducted. The result showed that Macrobrachium sintangense has a wide salinity tolerance and all individuals could survive in the experimental medium up to 20 ppt salinity level, but no individuals could survive in the 35 ppt salinity more than 24 hours.

Abstract

Incidence of Pneumonia and Enteistis on the proboscis monkey as Bekantan (Nasalis larvatus) was done at the Surabaya Zoological Gardens. Sixty one proboscis monkeys were evacuated from their habitat in Kaget island, south Kalimantan because of the habitat destruction. Thirty seven Proboscis monkeys were dead of Pneumonia and Enteritis by worms parasite infection. The preventive and treatment program with anti-biotherapy, liquid pertusion and anthelmentica have already been done as well as nutrition quality improvement and living environment to save the animals at Surabaya Zoological Gardens.

Abstract

This research is about pathogen capacity of the Helicoverpa armigera nuclear Polyhedrosis Virus (HaNPV) after irradiation by ultra violet (UV) light. The HaNPV is the one kind of the virus which attack the insect Helicoverpa armigera-attacker the some species of the crop life tobacco, cotton, potato, tomato. Because of that the HaNPV can be used as the biological control of the pest. Some researcher stated that the pathogen capacity of the HaNPV is decrease if the virus was expose in the ultra violet (UV) light. Because of the fact the virus in not useful as the biological control of the pest in the land corp. This research to test the statement. Laboratory experimental was done to tested the pathogen capacity of the HaNPV after irradiation treatment by the ultra violet light. The intensity of the UV light in this experiment were 28.7 lux, 97.3 lux, and 127.4 lux with the lighting period were 0, 1, 3, 6, 9, 12, and 15. The result of the research stated that the pathogen capacity of the HaNPV was not influenced by ultra violet light. So the virus is still useful as the biological control of the pest in the land crop.

Abstract

The aim of this study was to know the specific expose period of the Lymnaea sp.’s embyos and their age in order to utilization eggs of Lymnaea sp. in bioassay. Fifty individuals of Lymnaea sp. collected from Gonggan River Magetan were captured in laboratory. Egg cluster of each individual then was placed in petry dish which was filled by Baycarb 500 EC of 0.0001, 0.001 and 0.01 ppm. The result showed that 12 hours exposure in Baycarb 500 EC was the effective time since within 6 hours all of embryos were death and abnormalities of the survivals was detected in the embryos of 48 and 72 hours.

Abstract

This study was done in “Materia Medica�, Technical Implementation Unit East Java Health Service Bureau, Batu, East java, from May to December 1995. It has an altitude of approximately 750 m above sea level. This study has the objective of determining light intensity and fruit thinning which maximize strawberry yield of high quality. A three replicate two factors experiment, laid out in a completely randomized design with repeated measurements were. The first factor was shading intensity consisting of three levels: unshaded, shading intensity of 40% and 65%. The second factor was fruit thinning consisting of three levels: no fruit thinning applied, fruit thinning of 40% and 60%. The result indicated that: (1) maximum growth and yield of strawberry was attained at 40% incoming light, (2) removing 40% of fruits in a cluster increased weight of individual fruit, (3) shading which passed 40% of incoming light coupled with fruit thinning of 40% was the best combination, (4) shading increased vitamin C content of strawberry fruit, and (5) yield components might be predicted from tiller number, flower number per plant, and fruit weight average.

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

Characteristic and anatomical study of Gigantochloa apus was carried out to know the fiber structure, morphological, physical, and chemical properties on various age and part of culm height. The research was done by ex post facto design and the data was analyzed by observational description. For anatomical observation, materials were processed using paraffin, PEG, and wood method and maceration for fiber structure. The result showed that inter-nodus amount, diameter, and wall thickness was increase in older culm. Fiber length was 3.8 mm in average, and older culms have longer fiber than the young ones and within the same culm, the lower part had longer fibers than the upper part. The fresh density (0.97-1.17 g/ml) and the oven dry density (0.57-0.79 g/ml) of this bamboo, it was higher for the older culm than younger culm. Liquor sorption (in NaOH 5% solution) into bamboo chips was fairly good. The sorption into the young bamboo was faster and better than into older bamboo. Young bamboo culms contain more water than older culms and the top part within the same culm contain litte water than lower part. The total cellulose in young bamboo culm was higher than the older (64%-54%), but the lignin on the contrary in lower (14%-28%). At the bottom part, the lignin was higher than the upper prt. The ash content was high (1.6%-4.5%) and its fluctuated based on age and the height part of culm.

Abstract

There is an increasing commercial interest in enzymatic production of biologically active component, because there are a number of well-known advantages compared to chemical synthesis. One of the most valuable synthetic features of enzyme is their ability to discriminate between enantiomers of racemic substrates. Lipase have become of great interest to the chemical industries wing their usefulness in both hydrolytic and synthesis reactions. The aim of this work was to study the production of lipase by Rhizopus stolonifer UICC 137, and determine the crude lipase preparation characteristics. The lipolytic activity was determined by titrimetric method toward oil-arabic gum emultion as a substrate. The strain produced lipase at appreciable lipolytic when cultivated for 72 hours in medium containing 3% glucose and 1% olive oil. Our data suggest that the strain produced lipase since the exponential phase of its growth. Lipase with optimum lipolytic activity was obtained at late stationary phase. The optimum condition for lipolytic activity measurement were pH of 7.5 and temperature 37oC, the crude enzyme had a specific activity 20.2 unit/ mg protein, the Vmax was 15.1 mol/ min and KM was 12.5 mg/ ml. The crude enzyme retained 79.9%, 68.0% and 52.6% of its lipolytic activity, when incubated for 90 minutes at temperature of 40, 50, and 60oC respectively.
