Daily Activities Pattern and InteractionBetween Banteng and Deerin Sadengan Grazing a Area in Alas Purwo National Park, Banyuwangi, East JavaThis research was aimed to compare the pattern of daily activities between banteng and deer, and their interaction on using feeding ground in Alas Purwo National Park, Banyuwangi, East Java. Methods used in this research were scan sampling, focused on groups of banteng and deer and focal animal sampling for four chosen individuals from each group. The observations began at 06.00 until 18.00. Daily activities recorded were resting, moving, feeding and drinking. Data analysis was done through arrangement of an ethogram to show daily activity and the time budget, and descriptive analysis to portray daily activity and interaction between banteng and deer. The results show that there are differences in the time used for resting and feeding between banteng and deer. Banteng used feeding ground more for resting (93,2%) and moving (5,7%). While deer used more for feeding (36,6%) and resting (61,8% ). Among chosen individuals of banteng and deer time variation in daily activities was apparent. Adult female of banteng has the highest time for resting (10,6 hours). It also occurred in adult female of deer (8,4 hours). Individual of deer which has the highest time for feeding is offspring with duration of 6,1 hours. Interaction between banteng and deer on using feeding ground tended toward symbiosis of commensalisms, in which they use it together without fighting. They too will vocalize together whenever other species wants to use the feeding ground.

Dendrogram Zoning of Mangrove Growth Based on Its Habitat in the Rehabilitation Area on the North Coasts, West Region of Central JavaThe growth of rehabilitated mangrove, although planted at the same time, shows differences in terms of density and height growth. Such condition is visible in the North Shore of Brebes, Tegal and Pemalang Regency.The research result shows that mangrove growth planted in 2001 on the North Shore of Brebes, Tegal and Pemalang Regency is not apart from several factors, among others are its habitat physical-chemical factors. The result of regression correlation analysis shows that the habitat factors which play an important role in the vegetation density are salinity, temperature and plankton population. Meanwhile, the most dominant factor which determines the vegetation height growth is salinity and phosphor. The combination role based on its habitat shows that mangrove growth in Brebes Regency on proximal (1P) and medial (1M) zone and the one in Pemalang Regency on proximal zone (3P) has the shortest cluster, so that those research locations have similarity on vegetation growth and its habitat factors. Meanwhile, the proximal (2P) zone in Tegal Regency is similar with the medial (2M) zone. Mangrove growth on distal zone in Tegal Regency has less good growth parameter and habitat factors compared to that of in Brebes and Pemalang for containing more sand.From the research result, it can be concluded that the existence of habitat factors salinity, plankton population and phosphor have to be taken into consideration if a mangrove area will be rehabilitated/planted especially using Rhizophora mucronata seedlings. In order to reach the maximum achievement, one thing which has to be taken into consideration is the habitat clustering of the planted area, especially in Brebes, Tegal and Pemalang Regency area.

Effect of Lamination Pattern of Tali Bamboo (Gigantochloa apus Kurz) Beam on Density, Delamination, And Rupture StrengthBamboo is a potential species as its price is relatively less expensive than wood logs while it also represents a fast growing plant and is easy to plant. In general bamboos in South Kalimantan have not been exploited optimally. Its utilization for construction purposes is very limited. This study aims to identify the effects of lamination pattern on the density, delamination and rupture impregnability (Modulus of Rupture, MoR) of laminated bamboo blocks, with the combinations of a (reed wall- reed wall), b (reed wall-husk), and c (husk- husk and reed wall-reed wall). The results showed that lamination patterns affected the density, delamination and rupture impregnability of the laminae produced. The average density (kg/cm3) is 0.5321, 0.6923, and 0.6746 for treatments a, b, and c respectively. Delamination percentage (%) is 6.55, 16.65, and 21.1, while the rupture impregnability level (kg/cm2) is 228.99, 152.09,and 171.97 for treatments a, b, and c respectively. Delamination percentage of less than 10% suggets that the laminae produced can be used for building construction. that It is concluded that lamination pattern of reed wall-reed wall gave the best performance of bamboo lamina with the average density of 0.5321 kg/cm3, the delamination percentage of 6.55% , and the rupture impregnability level of 228.99 kg/cm2.

Human Activities and Distribution of Banteng (Bos Javanicus D’alton 1832) in Alas Purwo National ParkThis study aims to comprehend whether human activities contribute to the presence of banteng (Bos sundaicus d’Alton 1836) in the Alas Purwo National Park (APNP). We laid continuous strip line transects from centre of human activities to the direction of core area of APNP. Three locations were selected: Sadengan grazing area, Giri Salaka Hinduism praying area, and Kutorejo village; representing low to high human disturbance respectively. We collected both direct and indirect presence of banteng as well as human activities within 20 metre strip lines with 10 metre width. Data were compiled each 100 metres and analyzed with means comparison to observe difference among locations. Correlation analyses were used to assess the relation between distance from centre of human activities, human activities and banteng presence. Regression analysis was used when significant correlations found.Our non parametric test showed that human disturbances are significantly different among sites (Kruskal Wallis Test; df 2 = 6.220, p< 0.05). In similar tendency but different manner, it is showed that the different levels of human disturbance conveyed significant difference in number of banteng’s tracks (Kruskal Wallis Test; df 2 = 18.888, p< 0.05). The distance from centre of human activities is negatively related to number of human tracks (Spearman rho; r2= -0.307 N= 64, p<0.05*) and also to number of banteng’s tracks (Spearman rho, r2= -0.728 N= 30, p<0.05**). The regression analysis showed that number of human tracks explained 18.6% of total variation on number of Banteng’s tracks, while distance from centre of human activities explained 59%.

Level of Food Preference of Bawean Deer (Axis kuhlii) on Food Species in Wildlife Sanctuary and Nature Reserve of Bawean IslandThis research has a background on the importance of food preference of Rusa Bawean (Axis kuhlii). This information can be used to ensure the adequacy of preferred food availability within their habitat. This paper aimed to estimate food preference of Rusa Bawean employing faecal analysis. The technique was selected because it is safe for the animal and is easy in data analysis and interpretation. To achieve the aim, quasi experimental design was applied to 30 vegetation plots and 60 faecal samples. Data was collected during January 2005 and June 2006 in the area of Wildlife Sanctuary and Nature Reserve of Bawean Island. Data was analyzed with chi-square test and food selection index. Result shows Rusa Bawean have preferences on some of food species, and they do not select their food species randomly according to its abundance. Preferred food species include Kabak-kabakan alas (Brachiaria distachya), Talioar (Panicum cordayum), Gadung (Dioscorea hispida), Andudur (Caryota mitis), Rombok putih (Merremia peltata), Pele (Urena lobata) and Kabak-kabakan merah (Ischaemum timorense). Whereas avoided food species include Lating-latingan (Scleria hebecarpa), Ancucu (Pericampylus glaucus), Lambu Merah (Paspalum conjugatum), Alang-alang (Imperata cylindrica), Padi-padian (Centotheca lappacea), Lente-lentean (Fimbristylis dichotoma), Taliata (Lygodium circinnatum ) dan Kayu sape (Symplocos adenophylla).

Effect of Tobacco Extracts on Apus Bamboo (Gigantochloa apus Kurz) resistance against Drywood Termite Cryptotermes cynocephalus Light (Gigantochloa apus Kurz) AttacksBamboo is one of community forest products and people use it for many purposes. Due to insect attack such as termite, the life time of bamboo product is short. To avoid chemical pollution in bamboo preservation process, tobacco extract was used.Tobacco was extracted in water, in the amounts of 100, 150 and 200 g in 1 l of water, at temperature of 70-80°C for 3 hours. Bamboo trees were cut, the bottom parts were soaked in tobacco extract solution for 1, 3 and 5 days. Samples were cut into 5 cm x 3 cm x bamboo thickness at the bottom, middle and upper parts of the bamboo tree. After being air dried, each sample was exposed to 50 dry wood termites in a small glass tube for two months.The results showed that bamboo preservation by diffusion with high concentration of tobacco extract (200 g tobacco extracted in 1 l of water) resulted in 61% termite mortality.
