Judul: Hubungan antara konservasi lahan pertanian dengan tingkat kesejahteraan petani: Kasus Desa Kibin, Kabupaten Serang, Propinsi Banten
Abstrak: Conversion of agriculture farm to non agriculture is triggered by industrial sector expanding which happened so quickly. It causes high requirement of farm for industial sectors. Most of agriculture farm convertion didn't do by farmer who has the farms, because they sold the nonproductive farms to another who probably an investor or the owner of factory. This research is done in Kibin Village, Kibin Subdistrict, Serang Regency, Banten. Using approach qualitative and quantitative, this research try to study the factors that influence the farmer to sell their farms to other party. Generally, condition of farmers after agriculture farm conversion has not been prosperous yet, because from 5 prosperity indicator that show the relation of between agriculture farm conversion with farmer prosperity, only 2 indicators describe the farmer prosperity after agriculture farm conversion, those are rate of ability to send their children to school indicator and condition of house indicator. While 3 other indicator, those are consume pattern, ownership of asset, and rate of earnings doesn't show significant result. Type of agriculture farm conversion that happened in Kibin Village is pertained into Sporadic Gradual Patterned Conversion Type which is conversion caused by two main factors, those are unproductive/lessproductiveleconomical useful and perforced condition of conversion actors.

Judul: Analisis dampak alih fungsi lahan pertanian terhadap kemandirian pangan di Kabipaten Subang (studi kasus : Desa Belendung, Kecamatan Cibogo)
Abstrak: Increasing of population and economy growth in Indonesia, particularly in industrial sector, leads to the demand increasing of land. Whereas the land supply is not able to fulfill the demand. This caused the problem of decreasing in agricultural land, especially rice field which converted for public housing and industrial development. There was a fluctuative rate of land conversion in Subang district. In the periode of 2003-2012 the total rate of conversion was -0,57 percent or the average rate of conversion was -0,057 percent. There are the factors that affected land conversion on macro scale in Subang district such as public housing and number of industry. There are the factors that affected land convertion on micro scale in Subang district such as land area and farm revenue. Besides that, land price was significant affected of farmer decisions for selling or converting them land. Farmers total revenue have been decreased as to be as Rp 1.090.762/month. Besides farmer revenue, occurring of land conversion decreased rice production. Rice production lost by 231.241 ton or Rp 1.107.460.400.000. The simulation result of food reliance with assumption productivity and consumption rate are constant showed that rice production in Subang district can’t supply their needs on 2100 with the number of short coming is 2.773 ton. There was various aspect of policy implication which could overcome land conversion such as social aspects, economy aspects, and environmental aspects.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
