Cultivation of beef cattle in Indonesia is mostly carried out by smallholder farms. Therefore, the beef cattle assistance program from the government often involves farmer groups through a livestock raising system. This study aims to determine the impact of implementing various disturbance patterns applied by farmer groups on the development of beef cattle populations. The research was conducted from February to June 2021 in Padang Jaya District, North Bengkulu Regency. Data was collected through interviews with various informants, namely from the Agriculture Office of North Bengkulu Regency, Animal Husbandry Officers from Padang Jaya District, and Management of Farmer Groups. Reports on assistance for the livestock raising program in Padang Jaya District in the 2016-2020 period originating from the Agriculture Service became the basis for searching field information. Eight farmer groups from four recipient villages of the livestock raising program identified the patterns of disturbances and their impact on livestock population development. Secondary data related to this study were collected from BPS reports, Livestock and Animal Health Sector - North Bengkulu District Agriculture Service, and the Padang Jaya District Agricultural Extension Center. The data and information obtained are discussed descriptively. The results showed that there were four patterns of beef cattle raising applied by breeders, namely: (1) one calf deposit, (2) one calf deposit plus Rp. 300,000, (3) deposit of two children, and (4) patterns of rioting with a profit-sharing system. All of these rioting patterns increased the beef cattle population belonging to individual breeders, but only the rioting pattern with the deposit of two calves and a profit-sharing system was able to increase the population of ruminant livestock owned by farmer groups.

Tapir Asia ( Tapirus indicus) is a plant-eating herbivorous animal (Goltenboth et al., 2012). Habitats that are suitable for survival, such as the availability of sufficient food and an environment that supports tapirs for breeding and resting which occupy places of life in the form of swamp habitats, lowlands, mountains, hill forests, secondary forests, dense shrubs and palm plantations (Ministry of Forestry, 2013). Tesso Nilo National Park is one of the natural forest areas that still provides a habitat for the continued preservation and rescue of rare animals, including the tapir. This study aims to determine the habitat characteristics of the Asian tapir (Tapirus indicus) in the SPTN I area of Tesso Nilo National Park. Determination of the position of the Asian tapir can be known by collecting data using direct and indirect observation methods. The habitat studied was selected using a purposive sampling technique, namely by exploring locations that are home ranges for tapirs. Observations were made using 1 transect line in each different habitat type. There are a total of 2 transect lines, there are 25 observation plots in each line so that a total of 50 observation plots. Habitat characteristics suitable for tapirs based on tree crown cover were 1.77% -14.14% shrubs and secondary forest tree canopy cover 17.68% -99.79%. Habitat characteristics for tapirs based on the availability of forage plant species are mostly found in shrub vegetation, 27.272% -96.55%. Based on the slope factor, the slope is at a level of 1% -21%, this is included in the flat and sloping category, then based on the altitude it ranges from 42.01 masl to 71.96 masl. The distance between secondary forest vegetation and natural forest is 810.89 m-1,220.43 m and the distance between shrub vegetation is 2,537.39 m-3,084.49 m and the distance from the river to secondary forest vegetation is 8.98 m-317.41 m and scrub vegetation 24.52 m-398.75 m.
