"Banteng (Bos javanicus d?Alton) is naturally distributed throughout Asia. In Indonesia this species can be found in Jawa, Bali, and Kalimantan. The current population is small, making it categorized as an endangered species. Protection measures have been implemented in such national parks as in West Bali, Ujung Kulon, Baluran, and Alas Purwo. Scientifically, this species is a genetic resource potential for further domestication purposes. In fact this species has been traditionally utilized as a cross-breeder for Bali Cattle which originated from Bos sondaicus. Banteng is typically a crespuscular species, but due to disturbances it sometimes becomes nocturnal. The species generally live in groups of 5 to 15 individuals, with only 2 to 3 steers in a group, although groups with only one steer is not unusual. The groups spend most ,of their time grazing in a pasture. Alas Purwo is a national park located in Sothern Banyuwangi, East Jawa, and initially gazetted as an area for animal protection. The total area of this national park is about 43420 hectares, but the Banteng is usually found grazing in Sadengan a pasture area with a size of about 20 hectares. This thesis consists of two papers, i.e.,Daily behaviour of banteng, and Habitat selection for feeding. Samples of banteng have been taken directly, using the concentrated method, whereas the grass samples have been taken by using quadrates of 100 x 100 cm2, totalling 100 plots. Observations have been carried out in two locations, i.e., location I: around the tower, and location II: nearby and adjacent to the mountaineous area. The studies have been conducted from January 1996 to June 1996. The paper entitled Daily behaviour of bantengs concluded that (1). The environment significantly affected the daily behaviour of the cows.(2). Frequency of cows in pasture areas of Sadengan in Alas Purwo broken as if indicator of disturbance. It is recommended that to increase grazing intensity of cows, habitat management should be maintained properly, particularly monitoring of wild dogs. The paper entitled Habitat selection for feeding, concluded : (1). Potential of grasses in pastures of Sadengan in Alas Purwo National Park was very low, (2)Location of grazing areas was concentrated in one location, and was related to the biomass of grasses as their food resource. It is recommended that (1). Pasture areas of Sadengan in Alas Purwo National Park should be properly maintained, and (2). Grasses of Hyptis brevipes Porr. and Cassia Lora L. should be cut prior to flowering."
