Judul: Keterkaitan Pertumbuhan Penduduk dengan Perubahan Penggunaan Lahan Pertanian ke Non Pertanian dan Luas Lahan Kritis
Abstrak: Increasing population growth is one of factors affecting the use of a piece of land, where low-land-rent utilization tend to be converted into the higher-land-rent utilization. Land rent of non-agricultural uses which is higher than on-farm agriculture undeniably increase agricultural conversion, then could accelerate land degradation. Land degradation could be due to improper management which is not in accordance with its carrying capacity then initializing degraded land. The purpose of this research is: (1) to identify population growth and agricultural land use change to non-agricultural one, (2) to identify acreage of degraded land, (3) to compare agricultural land rent and non-agricultural uses, and (4) to understand the relationship among population growth, agricultural land use change and the acreage of degraded land. The analytical techniques utilized in this research include: (1) analysis of population growth and spatial technique to identify changes from agricultural land to non-agricultural ones, (2) spasial analysis to calculate hectarage of classified degraded land based on ministry of forestry, (3) descriptive analysis of land rent and the t test, and (4) correlation analysis to understand the relationship among population growth, land use changes and the acreage of degraded land. The results showed that population in Kecamatan Sukaraja grew at 7,6 % and Kecamatan Sukamakmur increased at 0,3 % in the period 2006-2009. The acreage of agricultural land use change to non-agricultural one in Kecamatan Sukaraja was 95,95 ha (4,5%) and in Kecamatan Sukamakmur was 232,74 ha (2 %). Kecamatan Sukaraja was comprised of 1.383,90 ha of non degraded land, 1.613,96 ha of potentially degraded land, 723,34 ha of somewhat degraded land, 166,78 ha of degraded land, and 0,16 ha of severe degraded land. Kecamatan Sukamakmur comprised of 984,07 ha non degraded land, 3.681,50 ha potentially degraded land, 4.330,52 ha somewhat degraded land, 7.658,94 ha degraded land and 44.08 ha severe degraded land. Comparison of the average value of agricultural land rent to non-agricultural one at CI 95 % indicates, that the non-farm business more lucrative than farming. Correlation coefficient of population growth and land use change in Kecamatan Sukaraja was 0,82 and in Kecamatan Sukamakmur was 0,92, the coefficient of population growth and acreage of degraded land of Kecamatan Sukaraja was 0,85 and of Kecamatan Sukamakmur was 0,91, while the coefficient of land use change acreage and degraded land in Kecamatan Sukaraja was 0,90 and in Kecamatan Sukamakmur was 0,98. These suggest positive relationship among all variables at 95% confidence level and implied that the higher population then more intensive changes from agricultural land uses to non-agricultural ones and the wider acreage of degraded land.

Judul: Analisis Perubahan Penggunaan Lahan Dan Aspek Sosial Ekonomi Yang Mempengaruhinya (Di Das Cipunagara Dan Sekitarnya, Jawa Barat)
Abstrak: Increased population causes an increase in food, clothing, and shelter. The demand for land to meet those needs is also increasing. Meanwhile, the availability of land to meet all the needs of human life is limited. This will encourage land use changes into other forms of land use. Changes in land use caused by many factors, including the social and economic factors. For example, the change of forest to farm because of the economic value of commodities, and because of the need for food increases with the increase of population. This study uses PODES data and Regency in Figures to determine estimators factor of social and economic conditions, then performed a multiple regression analysis to see the huge influence estimators factor of land use change that occurred in the study area. Changes in land use area was analyzed in the year 1990 - 2000, and 2000 - 2008. Analysis in the year 1990 - 2000 is done by district, and analysis of the year 2000 - 2008 conducted in 2 phases, namely district analysis and about rural. The results showed that the largest land use in three years of observation is the rice fields, ranging from 45% of total land use. Large changes in the same land use area between the years 1990 - 2000 differ from the period 2000 - 2008, as well as social and economic factors that influence it. The greatest changing of land use extent in 1990 - 2000 is forest area that decrease by 26,8% of the total changing. In the year 2000 - 2008, the greates of changing land use extent is settlement increased by 36,6%. In common, changes in land use area in Cipunagara watershed in the range year period 1990 - 2000 and 2000 - 2008, influenced by accessibility (distance to markets and road density). Meanwhile, according to the rural analysis of dominant factors that cause land use change is the accessibility (road density). Meanwhile, non-commercial land use change is influenced by a number of educational facilities and markets, while commercial land use change is influenced by availability of land (land that might turn into certain land use) and road density.
