Abstract

Abstract Rays are cartilaginous fishes that are commonly caught by fishermen in Java Sea especially in Jakarta Bay. One species of rays that has been oftenly caught is Himantura walga. Even though they are not categorized as target fishes, rays are susceptible to excessive fishing, due to their biological characteristics, so an effort is needed to conserve these fishes in the nature. As a first step to their conservation, an initial survey about its reproduction was done for Himantura walga. The survey covered spread of width size, sex ratio, growth pattern, sexual maturity level and the width size of males and females when they reach sexual maturity. Method used was descriptive with both market and purposive sampling. Chi square analysis showed that male and female ratio were well balanced. Result of regression showed that the width-weight correlation between male and female rays was allometrically positive. Most Captured males showed that their sexual maturity were at fully calcified stage (FC) while most females were at immature stage (TKG 1), according to their gonad condition. Males tend to reach sexual maturity earlier and have smaller body than females. Hence, it is advised for the fishermen to use selective fishing gears that are only able to capture adult rays. Key words: Himantura walga, rays, reproduction biology

Abstract

Abstract Frigatebird is one of seabird species found in Pulau Rambut Wildlife Reserve (SMPR). The bird activities include roost in fish pole, flying, foraging in the ocean and also roosting in SMPR at night. The aim of this research was to know roosting site used by frigatebird while at SMPR. This research was conducted in SMPR, Jakarta on August and September 2010 by descriptive method and survey techniques. Data was collected directly on the object of research. Frigatebird population was calculated directly by counting individuals one by one as they flew low in the air over SMPR. Frigatebird roosting site was also researched directly by observing frigatebird when going to roost. Furthermore, vegetation analysis was also conducted on trees in roosting site. Based on our obsevations, the population of frigatebird obtained in SMPR ranged between 87-193 birds. Frigatebird utilize Sterculia foetida tree to be used as a place to roost. This roosting site located in mixed secondary forest to the west and south SMPR close to mangrove forest. Average of height and diameter of S. foetida tree used to roost is 23.47 m and 42.26 cm. There were commonly 3 species of tree of frigatebird roosting site namely Ficus sp. (INP 16.91%), Allophylus cobbe (INP 16.78%) dan Diospyros maritima (INP 14.23). Key words: frigatebird, Pulau Rambut Wildlife Reserve (SMPR), roosting site

Abstract

Abstract Javan Hawk – Eagles is an endemic raptor species in Java Island which is protected by the state and listed as endangered by IUCN and CITES Appendix II. The population of Javan Hawk - Eagles has been greatly reduced due to large-scale of illegal logging and forest destruction. The initial step that could be taken to preserve this species is to study the population in its natural habitat. Thus, studying the population of Javan Hawk - Eagles was the aim of this research. The research was conducted at Gunung Salak, Gunung Halimun – Salak National Park in February to March 2011. Method used was explorative descriptive with look-down method on particular. Data were analyzed descriptively by describing the species’ distribution map by using ArcGIS and ArcView GIS 3.3 softwares. The results showed that the eagle population consisted of 13 individuals with density and abundance values of 0.183 individuals/km2 (1 individual/6 km2) and 2. The values fell into “few category” and the distribution pattern was categorized as “uniform”. The eagles’ habitats were forest and hills at 797-1.383 meters above sea level although they are seen more often in forest. Key words: Gunung Salak, Javan Hawk – Eagles, population

Abstract

Abstract Cashew (Anacardium occidentale L.) is a plant with high economic value. Conventional propagation of this plant still has obstacles, so an alternative techniques using tissue culture could be tried. One of the factors that determine the success of tissue culture techniques is the type and concentration of growth regulators was used. Growth regulator which have effect on shoot elongation is a cytokinin and gibberellin, this research tried to investigate the influence of combination cytokinin and gibberelin on in vitro shoot elongation of cashew. This research was conducted at BB-Biogen, Bogor on June-November 2010. The method in this research was to design experimental method with completely randomized design. The result was cytokinin could increase the length of shoots and quantity of shoots very well until 4 cm and quantity of shoot for 5. With the most effective cytokinin is zeatin of 5 mg/l. Key words: Anacardium occidentale L., cytokinin, elongation of shoots, gibberelin

Abstract

Abstract Ecological studies of reptiles in Java were rarely executed during the last decade, because many scientist have focused exclusively on taxonomical studies. Also, studies about diversity of reptiles which have been heretofore published mostly incorporated with amphibians, and nearly all of those studies concerning in unravel the diversity of amphibians. In Bodogol, Gede- Pangrango National Park, survey about reptiles diversity have been done frequently, but just few researches that have been published and most of all were short term research studies. Hence, a research that concern in studying diversity of reptiles become valuable to carry out. Herein, we studied the diversity of reptiles in Bodogol during November 2011 to March 2012. Reptiles’ species were collected by searching in available trail other than Tangkil, Cipanyairan I, and Cipanyairan II. Total of twenty three species of reptiles were found, encompassing six families (Colubridae, Elapidae, Viperidae, Scincidae, Agamidae, and Gekkonidae). Number species of reptiles occured in Bodogol were quite similar to other largest nature reserve areas within the same geographic range (e.g. Halimun-Salak and Ujung Kulon National Park). Despite its small in size, Bodogol contains various types of habitat which therefore could support a variety species of reptiles. Key words : bodogol, diversity, reptiles, java

Abstract

Abstract content in the tissue. Hypoxia can make the formation of free radicals or reactive oxygen species (ROS) which reactive to cell membrane. Body will avoid free radicals by producing antioxidant, such as catalase enzyme. The reaction between ROS and cell membrane will form malondialdehyde (MDA). Liver is the main location of catalase. This research was aimed to know the influence of hypoxia exposure toward catalase antioxidant activity and MDA content in the rat liver tissue. This research used experiment method with fully randomized design. Based on one way Anova test (p≤0.01), it was shown that there had no average difference on catalase activity and MDA content toward length hypoxia exposure. The conclusion of this research was no influence of hypoxia exposure toward catalase activity and MDA content in rat liver tissue. Key words: catalase antioxidant activity, hypoxia, malondialdehyde (MDA) content,rat liver tissue
