Abstract

The research on erosion level (TBE) in the sub watershed of Tapung kanan has beenconducted on February-March 2013 using the USLE (Universal Soil Loss Equation) bythe formula A = RxKxLSxC.P. The results showed that the change of use / land coverimpact on the actual increase in the level of erosion that occurs in each type of landuse. Erosion hazard level (TBE) which occurs in the sub watershed of Tapung Kanan,for each type of use / land cover has a magnitude which varies, with an average erosionrate of 130.18 tons / Ha / year, and the distribution for each class TBE is: very Low(SR): 16986.50 Ha (7.17)%; Low: 35343.73 ha (14.92%); Moderate: 142,155.01 ha(60.01%); high: 32109.48 Ha (13.55%) and very high: 10290.71 ha (4.34%). TSL valueof Tapung Kanan Sub watershed which obtained from this research ranged from 14.40-30.00 tons / ha / year, while the average value of the actual erosion of 130.14 tons / ha/ year, thus the Erosion hazard level of Tapung kanan Sub Watershed exceeds thepermitted threshold, the SDR value of 0.463, still below the SDR standard value of0.490.

The findings are that the social condition of the people is so plural for its ethnics, religions, races, and cultures. There are institutions and varied social groups with different identities which interacted and adapted to their society to fulfill their social needs to reach balance.  The social integration occurred by adjusting the various components of the living patterns which have the functions synergically.  Society is integrated based on the agreement on norms and values of the society in creating balance, regularity, and harmony.   The components of the social integration which are done by the people among other things are accommodations, coordination, assimilations, and amalgamations; which are aspirations and the potential of the uniqueness of the people and the cultures of the locals. People tried to adjust, cooperate and acculturate among them by respecting others for their diversity and expressions supported by knowledge, open-mindedness, communication, freedom of thought, belief, and conscience and they accept that people are varied in nature.
