Abstrak: Desa Cisarua terdampak perubahan rezim penguasaan, pemilikkan, penggunaan, dan pemanfaatan lahan akibat masuknya PT Hevindo. Perubahan rezim pada pola penguasaan, pemilikan, penggunaan, dan pemanfaatan tanah yang terjadi menuntut masyarakat dalam melakukan adaptasi dan perubahan pada strategi nafkah. Tujuan penelitian ini adalah untuk menganalisis tingkat perubahan modal nafkah yang dimiliki dalam rumah tangga pasca berakhirnya HGU PT Hevindo; menganalisis tingkat perubahan strategi nafkah rumah tangga petani pasca berakhirnya HGU PT Hevindo; dan menganalisis pengaruh strategi nafkah terhadap tingkat kesejahteraan rumah tangga petani. Data tingkat perubahan modal nafkah dan strategi nafkah diolah melalui tabel frekuensi, sedangkan analisis pengaruh strategi nafkah terhadap tingkat kesejahteraan diolah dengan uji regresi ordinal logistik. Kepemilikan modal nafkah oleh rumah tangga petani antara sebelum dan sesudah berakhirnya HGU PT Hevindo tidak terdapat perubahan yang signifikan. terdapat peningkatan sebesar 20% pada rumah tangga petani yang melakukan lebih dari dua strategi nafkah pasca berakhirnya HGU PT Hevindo., Cisarua village was affected by changes in the regime of control, ownership, use, and utilization of land due to the entry of PT Hevindo. Regime changes in patterns of control, ownership, use, and use of land that occur require the community to adapt and change their livelihood strategies. The purpose of this study was to analyze the level of change in living capital owned by households after the expiration of PT Hevindo's HGU; analyze the level of changes in farmer household livelihood strategies after the expiration of PT Hevindo's HGU; and analyze the effect of livelihood strategies on the welfare level of farmer households. Data on the level of changes in living capital and livelihood strategies was processed through frequency tables, while analysis of the influence of livelihood strategies on welfare levels was processed using ordinal logistic regression tests. There was no significant change in ownership of subsistence capital by farming households before and after the end of PT Hevindo's HGU. there was an increase of 20% in farming households that carried out more than two livelihood strategies after the end of PT Hevindo's HGU.

Abstrak: Pelaksanaan pengadaan tanah menyebabkan pihak terdampak kehilangan atau kekurangan akses terhadap tanah. Tanah merupakan salah satu modal nafkah yang penting dalam menjaga kestabilan penghidupan sebuah rumah tangga. Oleh karena itu, tujuan dari penelitian ini adalah menganalisis perubahan pemanfaatan modal nafkah dan strategi penghidupan yang dialami oleh pihak terdampak pasca pengadaan tanah. Metode penelitian ini adalah metode kuantitatif dengan menggunakan kuesioner. Jumlah responden dalam penelitian ini sebanyak 33 pihak terdampak yang memiliki mata pencaharian sebagai pedagang. Penelitian ini menggunakan uji hubungan dengan metode tabulasi silang dengan menguji hubungan karakteristik rumah tangga pedagang dan karakteristik pihak terdampak dengan perubahan modal nafkah akibat pengadaan tanah. Dilakukan pula uji tabulasi silang antara perubahan modal nafkah dengan strategi penghidupan pihak terdampak pasca pengadaan tanah. Hasil penelitian menunjukkan bahwa modal alam cenderung menurun, modal fisik cenderung meningkat, dan modal manusia cenderung tetap. Modal finansial dan modal sosial cenderung kurang dimanfaatkan oleh rumah tangga pedagang. Diversifikasi nafkah menjadi strategi penghidupan yang dominan dimanfaatkan oleh pihak terdampak., The implementation of land acquisition causes affected parties to lose or lack access to land.

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.
