KEJADIAN PENYAKIT RADANG PARU Pneumonia DAN ENTERISTIS PADA BEKANTAN Nasalis larvatus DI KEBUN BINATANG SURABAYA

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 A population estimation of proboscis monkeys (Nasalis larvatus) has been conducted in Manggar River, Balikpapan. In this non-conservation area, the anthropogenic activities threaten the proboscis monkey habitat. Boat survey technique was applied along ± 17 km of the river in the morning and evening. The number of proboscis monkeys in the surveyed area was estimated to range from 57 to 69 individuals with estimated population density of 4.75 individuals/Km2. Moreover, the population of this primates was divided into 4 groups and the sex ratio between adult males and females was 1:2.33. The proboscis monkeys were distributed in the middle of the river to the upstream. The highest population was found in the upstream area with less human activities. Conservation efforts in the Manggar River need to be carried out considering the proboscis monkey habitat in the area has been fragmented and isolated. These efforts could involve local economic communities.

AbstractThe population of the threatened proboscis monkey Nasalis larvatus, a Bornean endemic, in the Pulau Kaget Nature Reserve, South Kalimantan, Indonesia, is extinct. Until 1997, this small, isolated population, estimated at c. 300 individuals, had been pushed towards the fringes of the reserve by illegal agricultural expansion. As food sources became depleted, the population apparently exceeded the decreasing carrying capacity of the reserve and was reported to be starving to death. As a solution, 84 animals were translocated to nearby, unprotected sites, resulting in 13 fatalities. An additional 61 animals were taken to a zoo, where 60 per cent died within 4 months of their capture. There was neither a proper pre-translocation assessment of the suitability of the release sites, nor a proper post-translocation monitoring programme for the released animals. We conclude that the Pulau Kaget reserve and its proboscis monkeys have been poorly managed. We provide some suggestions to improve the effectiveness of conservation efforts in Indonesia.

Wardatutthoyyibah, Pudyatmoko S, Subrata SA, Imron MA. 2019. The sufficiency of existed protected areas in conserving the habitat of proboscis monkey (Nasalis larvatus). Biodiversitas 20: 1-10. Proboscis monkey (Nasalis larvatus) is an endemic species on the island of Borneo. Their population size progressively decreased because they are very sensitive to any habitat destruction and human activity. The population of proboscis monkey in 2008 was estimated at only approximately 25,000 in total, of which only 5,000 within the conservation areas. However so, the continuation of habitat degradation is hardly prevented in non-protected areas. To solve the problem, the Indonesian government commits to increase the population of the proboscis monkey, particularly outside the protected areas. To support this goal, the distribution data of N. larvatus for conservation planning has become necessary. This study aims to build predictive models of the N. larvatus in Kalimantan and to measure how big the overlap between the habitat and the land use activity (protected areas, concession areas, plantation, and agriculture areas). The study used the Species Distribution Modelling (SDM) approach and Maximum Entropy (MaxEnt) software. We collected recent data from N. larvatus and a number of environmental variables. The result shows that only 5% of the total of Kalimantan area is suitable for their habitat. The overlap between N. larvatus distribution, land use, and land cover map reveals that only 9% of the distribution lies in protected areas, while 37% lies in concession areas and 27% lies in agriculture and plantations areas. We discuss the spatial distribution of the model and current situation of the land use policy in Kalimantan to provide scientific guidance for the Indonesian government to make a master plan for conserving endangered species N. larvatus.
