Judul: The Level of Changes in Farmer Household  Livelihood Assets and Livelihood Strategies After PT Hevea Indonesia's HGU Expires.
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.

Judul: Land Cultivation and Household Welfare in the Ex-HGU Location of PT Hevindo
Abstrak: Tanah dengan status Hak Guna Usaha (HGU) yang tidak dimanfaatkan dengan baik atau ditelantarkan dapat memicu konflik dengan penduduk lokal, seperti terjadi pada lokasi eks HGU PT Hevindo di Kecamatan Nanggung, Kabupaten Bogor. Petani penggarap yang tergabung dalam organisasi AMANAT saat ini mendorong pemerintah untuk melaksanakan reforma agraria di 37 blok yang berada di lokasi eks HGU tersebut. Penelitian ini bertujuan mengkaji pengusahaan tanah di Blok Langkob Kaler Desa Cisarua, Kecamatan Nanggung dan hubungannya dengan tingkat kesejahteraan rumah tangga yang menguasai tanah di blok tersebut. Penelitian ini menggunakan metode sensus dengan kuesioner yang ditanyakan kepada semua rumah tangga responden yakni sebanyak 47 responden. Selain itu, wawancara mendalam dan observasi juga dilakukan untuk mengumpulkan data kualitatif. Hasil penelitian menunjukkan bahwa terdapat hubungan antara karakteristik responden dan tingkat penguasaan tanah dengan tingkat pengusahaan tanah. Selanjutnya, terdapat hubungan antara tingkat pengusahaan tanah yang mencakup jenis penggunaan, jenis pemanfaatan, tingkat usahatani, dan kontribusi pengusahaan tanah eks HGU terhadap total pendapatan dengan tingkat kesejahteraan rumah tangga responden., Land with Hak Guna Usaha (HGU) status that is not well utilized or abandoned can trigger conflicts with local residents, as happened in the former HGU location of PT Hevindo in Nanggung District. Tenant farmers who are members of the AMANAT organization are currently encouraging the government to implement agrarian reform. This study aims to assess land cultivation in Langkob Kaler Block, Cisarua Village, Nanggung Sub-district and its relationship with the welfare level of households. For this purpose, the census method was used by administering questionnaires to all these households. A total of 47 respondents from all these households were interviewed using the questionnaire instrument. In addition, in-depth interviews and participant observation were also conducted to collect qualitative data. The results show that there is a relationship between the characteristics of respondents and the level of land tenure with the level of land cultivation. Furthermore, there is a relationship between the level of land cultivation with the welfare level of respondent households.

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.
