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: Konversi Lahan Pertanian dan Sikap Petani di Desa Cihideung Ilir Kabupaten Bogor
Abstrak: This study showed that the patterns of conversion is mostly occurs rapidly and by switching control to others. Converted lands generally used for housing. Factors affecting land conversion can be categorized into internal factors such as urgent economic needs and the desire to change the fate, and external factors such as population growth and government policies. The impact of land conversion on the socioeconomic conditions consist of reduced rice yield, decreased farmers’s income, reduced household food security, reduced employment opportunities in agriculture, farmers’s limited access to agricultural land, and others. However there are positive impact as well, that is construction of housing may indicate the development of rural economy. The attitude of farmers to conversion of agricultural land has no relation to the characteristics of the respondents including gender, age, educational level, farm employment status, number of dependents in the family, income level, as well as broad and land tenure.

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.
