Abstract

Information on the potential of forest stands is necessary to know the state and the amount of natural resources contained therein. Potential stands a forest area estimates can be obtained by various methods. This study aims to estimate and compare the potential stands between sample units and determine the most efficient unit instance performed in forest crop production. This study uses systematic random sampling with a sample on circular plots and tree sampling. Circular plots used area of ​​0,05 ha (12,62 m diameter) and tree sampling using 6, 8 and 10 trees in the sample. The results showed the best efficiency levels obtained 6 trees sampling, and accuracy approaching sample of circular plots. Circular plots had the lowest sampling error. Sampling error is less than 5%, so the circular plots had the highest accuracy compared to other sample units. Thus, the circular plots is a sample of the recommended applied to the public plant forest. Keywords: Potential stands, Samples, sampling error, efficiency

Abstract

Land use and land cover is an important component in understanding the interaction of human activities with the environment. Forest management include the planning and supervision in the Karo regency forest becomes very important to do in order to prevent degradation of the forest more severe. The purpose of this study was to quantify changes in land use from 1997 to 2012 and makes predictions extensive land use in 2018 and 2024. This research methods  to utilize remote sensing technology and geographic information systems (GIS) and then compare the 5 maps of land use interpretation of Landsat ETM + (1997, 2000, 2003, 2006 and 2009 ). Classification results show that the Karo Regency has 11 land cover classes. The equation obtained from the linear regressions used to predict land cover area.The results showed that widespread changes in land cover occurred in dryland farming into rice paddies. Therefore, it is necessary that proper spatial planning in Karo Regency. Key word : land use change, land cover, landsat ETM+ image

Abstract

Deer are wild animals which have been developed in breeding place because their habitat is corrupted. One of the breeding places in developed is CPL (Cinta Pesona Ladangku) breeding place at Kuala Bekala, North Sumatera. The observed parameter was the correlation between bio-ecological aspect and and the population development of deer. The research used descriptive method. The result of the research showed that the minimum of air temperature in CPL breeding place was 220 C and the maximum of air temperature was 340 C. The population of deer in CPL breeding place has surpassed the capacity of the animal pen. Viewed from some bio-ecological aspects, Bawean deer could not multiply in number in CPL breeding place. The age-structure was an upside down pyramid where the number of fawns was fewer than that of deer. The deer breeding technique needs special attention in order to increase the number of deer population.Keywords : Deer, Breeding place, Bio-ecology, Population.

Abstract

The hybrid Eucalyptus urograndis IND 47 is a hybrid between Eucalyptus urophylla ST Blake and Eucalyptus grandis ex Maid W.Hill developed in operational scale in PT Toba Pulp Lestari Tbk (TPL). Therefore, a research had been  conducted on E. urograndis IND 47 in Estate A, sector of Aek Nauli, PT TPLTbk. The aim of this research was to predict biomass of E. urograndis IND 47. The results showed that the biomass of E.urograndis IND 47 in Estate A was 8,431.25 tons for total area of 367.38 ha compartment with an average biomass was 22.95 tons /ha with ages of 1-3.3 years. Biomass differences caused by differences in ages of trees, number of trees in each compartment and environmental factors.Keywords: biomass, Eucalyptus urograndis IND 47, PT Toba Pulp Lestari Tbk
