Abstrak: Pengembangan masyarakat berbasis ekosistem dipandang sebagai sebuah strategi dalam mencapai pembangunan berkelanjutan sekaligus pemenuhan kebutuhan hidup masyarakat. Pengembangan masyarakat yang mengedepankan prinsip pemberdayaan tidak dapat terwujud tanpa adanya kerjasama masyarakat dalam wujud aksi kolektif. Tujuan dari penelitian ini adalah menganalisis hubungan antara aksi kolektif dan implementasi pengembangan masyarakat perbasis ekosistem, serta keterkaitannya dengan keberlanjutan program dan lingkungan. Metode yang digunakan dalam penulisan ini adalah data kuantitatif yang didukung dengan data kualitatif dalam melengkapi data. Data kuantitatif diolah menggunakan uji korelasi Pearson Product Moment dengan pemilihan responden sebanyak 30 orang menggunakan metode sensus. Hasil penelitian ini menunjukkan: 1) Lebih dari 90 orang responden menampilkan tingkat aksi kolektif berupa identifikasi kolektif, solidaritas, dan komitmen, yang termasuk Kuat; 2) Sekitar 60% orang responden memiliki intensitas implementasi prinsip pengemas berbasis ekosistem Tinggi, namun masih ada 30% yang Sedang yaitu pada organisasi SDM, data, dan kerjasama; serta 3) Ada korelasi antara tingkat aksi kolektif berorientasi identitas dengan intensitas implementasi prinsip pengembangan masyarakat berbasis ekosistem sebesar 0,728 (p<0,05)., Ecosystem-based community development is a strategy to achieve sustainable development as well as to meet the needs of people's lives. Community development that prioritizes the principle of empowerment cannot be fulfilled without cooperation in the form of collective action. Therefore, the objectives of this study are to determine the correlation between collective action and the implementation of ecosystem-based community development principles, and also its relationship with program and environmental sustainability. The research will use the quantitative data with the support of qualitative data. Quantitative data was processed using Pearson Product Moment Correlation Test with 30 respondents selected by the census method. The results of this study indicates that: 1) More than 90 respondents displayed a level of collective action in the form of collective identification, solidarity, and commitment, which included Strong; 2) Around 60% of respondents have a high intensity of implementing ecosystem-based packaging principles, but there are still 30% who are moderate, namely in HR, data, and collaboration organizations; and 3) There is a correlation between the level identity-oriented of collective action and the intensity of implementation of ecosystem-based community development principles of 0.728 (p<0.05).

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.
