Judul: Population Size and Spatial Distribution of Activity Tracks of Sun Bears (Helarctos malayanus, Raffles 1821) at the PBPH Area of PT Telaga Mas Kalimantan
Abstrak: Informasi tentang ukuran populasi dan sebaran yang menentukan keberadaan beruang madu diperlukan oleh PT. TMK sebagai salah satu bahan pertimbangan dalam merumuskan strategi konservasi keanekaragaman hayati khususnya beruang madu. Penelitian ini bertujuan untuk mengidentifikasi ukuran populasi dan sebaran spasial jejak aktivitas beruang madu serta hubungannya dengan karakteristik habitat di areal kawasan. Data dikumpulkan menggunakan metode album melalui camera trap, pengamatan jejak aktivitas dengan transek jalur dan analisis vegetasi. Data dianalisis ukuran populasi dengan menentukan jumlah individu yang teridentifikasi, menentukan sebaran jejak aktivitas secara spasial untuk menentukan pola sebaran, serta uji chi-square untuk menentukan hubungan antara sebaran jejak aktivitas beruang madu dengan karakteristik habitat. Berdasarkan hasil camera trap ukuran populasi didapatkan enam individu beruang madu dengan data persebaran 27 jejak aktivitas yang meliputi 26 cakaran dan satu bongkahan, tersebar secara mengelompok yang dipengaruhi oleh jarak dari sumber air dan kerapatan vegetasi pada tingkat pertumbuhan tiang., Information on population size and distribution that determine the presence of sun bears is needed by PT TMK as one of the considerations in formulating biodiversity conservation strategies, especially sun bears.. This study aims to identify the population size and spatial distribution of sun bear activity tracks and their relationship with habitat characteristics in the area. Data were collected using the album method through camera traps, observation of activity tracks with transect lines and vegetation analysis. Data were analyzed for population size by determining the number of individuals identified, determining the distribution of activity traces by spatial and morisita index, and chi-square test to determine the relationship between the distribution of sun bear activity traces and habitat characteristics. Based on the results of the camera trap population size, six sun bears were found with distribution data of 27 activity traces including 26 scratches and one chunk, scattered in groups influenced by distance from water sources and vegetation density at the pole growth level.

Judul: Penggunaan Ruang oleh Beruang Madu di Areal Konservasi PT. RAPP Estate Meranti
Abstrak: The malayan sun bear (Helarctos malayanus Raffles 1821) in Indonesia can only be found on the island of Sumatera and Borneo. Malayan sun bear are experiencing populations and habitat threats either caused by natural or humans disturbance. Malayan sun bear that exist in the conservation area of Meranti Estate needs to be efficiently managed so that this species remain sustainable. Conservation efforts need to be supported by scientific information based on the existence and condition of suitable habitat for this species. This research was conducted in Conservation Area of PT. RAPP Meranti Estate, Pelalawan, Riau from June to July 2012. The objectives of this study were to identify the existence and habitat use of sun bear and also to identify dominant habitat components that determine the presence of sun bear. The methods of this study were vegetation analysis, line transect, field observation and drawing the habitat profile. Vegetation analysis were made in two vegetation type that is Tall Pole Forest (TPF) and Transition Forest (TRF). Sixty seven plant species from thirty families were found in TPF. TPF was dominated by Syzygium inophyllum and Madhuca motleyana. Fifty seven plant species from twenty six families were found in TRF. TRF was dominated by Acmena acuminatissima, S. inophyllum, Mangifera griffithii and Blumeodendron tokbrai. The existence of sun bear determined by indirect encounter survey. Habitat use by sun bear was both on TPF and TRF vegetation type. Sun bear only use trees on their daily activity. Average height and diameter at breast height of the trees that used by sun bear was 20 m and 51 cm. Based on factor analysis, the dominant habitat factors that determined the existence of sun bear were vegetation density, canopy cover, the amount of tree and feeding tree individual, the amount of tree and feeding tree species and the distance from production
