Abstract

Tapir is a large endemic mammal on the Sumatra island, this animal is prioritized for conservation because it is categorized as an endangered species. The population is at risk of extinction >20% over a 20 year period, when no conservation efforts are made in accordance with their habitat. Tapirs can live in swamp habitats, lowlands, mountains, hilly forests, secondary forests, shrubs and palm plantations. All of the most important types of habitat are the availability of food, water and shelter. A habitat that is suitable for the survival of the tapirs is needed, such as the availability of sufficient food and an environment that supports tapirs to breed. This research aims to find out the characteristics of Asian tapir habitat (Tapirus indicus) in several types of primary forest vegetation, secondary forests and shrubs in the working area of Resort Lahai SPTN II Belilas Bukit Tiga puluh National Park and surrounding areas in Riau Province. This research was conducted using purposive sampling method by determining the characteristics of tapir habitat.

Abstract

Gambier cultivation location is usually carried out on sloping land which results in decreased land carrying capacity due to soil erosion. This research was to determine whether the factors of altitude and slope are related to the production of gambier plants and other factors related to gambier production. This research was conducted in Lima Puluh Kota Regency, West Sumatra in September 2020. The data collection methods is to use the interview method, observation and document study. Interview and observation methods were used to obtained gambier production data, gambier harvesting, gambier processing, general conditions of the research location, visual appearance of soil erosion, height of the gambier growing area, topography and soil type. Indirect data were collected using the document study method. The selection of informants was carried out by purposive sampling with a total of 10 people. Data analysis used qualitative descriptive analysis by linking the informants 'answers with document studies, then doing a description in the form of gambier production as outlined in the informants' responses. Altitude has no relation to the production of gambier, but the factors of price, treatment process, soil type and the choice of mixed plant species are factors related to gambier production in Lima Puluh Kota Regency. The slope factor has no relation to the production of gambier in Lima Puluh Kota Regency. Land owners still observe the principles of soil and water conservation by applying mulch (ground cover) from the dregs of gambier and conducting mixed planting with seasonal and annual plant types.

Abstract

Phantera tigris sumatrae has a fairly high adaptability to changes in habitat outside its natural habitat, as for changes in areas that have changed functions which were formerly forest areas but are now community gardens, which causes Sumatran tigers to leave and enter community settlements in search of food sources due to forest area shifts. Sumatran tigers can still be found on the island of Sumatra, Lack of public knowledge about Sumatran tiger activities that can endanger livestock and endanger human lives at the same time. Therefore, Sumatran tigers are hunted, captured, and snared. Therefore, information on Sumatran tiger activities is important in an effort to preserve and protect Sumatran tigers. This research method is focal time sampling. This research was conducted from July 2021 to August 2021 for 30 effective days every day to collect daily data on Sumatran tigers. The objects observed in each individual based on sex and age were adult females and juvenile males. Based on the results of the study, it was concluded that the highest daily activity in adult females was moving behavior with a percentage of 21.0%, followed by rest 18.7%, social 1.2%, grooming 1.0%, eating and drinking 0.4%, defecation and urination 0.3%, other activities 57.4%, while for adolescent males the highest activity was moving with a percentage of 12.64%, followed by rest 5.47%, Grooming 0.44%, social 0.37%, eating 0, 30%, other activities 80.32%. Suggestions from this study are the need for further research in order to determine the behavior patterns and adaptations of the Sumatran tiger at the Dharmasraya Sumatran tiger rehabilitation center, West Sumatra.
