Abstract
ABSTRACT
Papua has a diversity of natural and human resources. The ecological has
greatly influence the socioeconomic life of the community culture. The bill on
Recognition and Protection of the Rights of Indigenous Peoples, which recognizes
customary rights existed long before the independent of Indonesia, August 17,
1945, requires the identification of indigenous territories by indigenous people
and / or government. The problem is the landarea itself which is a basin or
subbasin. Papuan tribes or clans customaryly set limits of their ground based on
natural signs such as river flow or mountain ridge line.
An extensive study of communal land which is nothing but a basin or sub
basin, will reveal the geomorphologic relationships with communal land boundaries,
thus helping the process of mapping the boundaries of customary land quick
and accurate, to obviate conflicts between Natural Resources and Social Cultural
resources in the West Papua province.
The current morphology of Bird Head is a reflection of the lithology and
structures that control the process during geological time period . Bird Head is
none other than the northern edge of the Australian plate that has undergone horizontal
and vertical dynamic pressure and other geological processes. Tectonic
framework of the Bird Head region has made it a potential for the presence of
mineralization, as to attract investors to perform variety of mineral Exploration.
The method of maping is doing field mapping, supported by intense discussion
with community leaders. The communal land area, river density,
biofurcation ratio, gradient of rivers order 1, then determined by using mapinfo
program. Further statistical tests performed by multiple correlation techniques
and multiple regression, in which the area which are communal land or basim –
sub basin become dependent fariable while the rivers density, biofurcation and
gradient of river 1st order become the independent variable.
As the findings: Bifurcation ratio affected the land area or basin – sub
basin significantly, where the Individual influence is 31.78 %. River density and
1st order gradient of streams was not significant. Simultaneously the three independent
variables contribute influences by 33.3%, it is especially significant since
there are many of variables of basin geometry that have not been included in the
calculation.
