Judul: Strategies of Land Management in Supporting Soil and Water Conservation in Social Forestry Land Mendelem Village
Abstrak: Pengelolaan lahan yang selaras dengan usaha konservasi tanah dan air perlu dilakukan untuk mengoptimalkan nilai sosial dan ekonomi dengan tetap mempertahankan nilai ekologi agar tetap lestari, terutama pada lahan dengan kelerengan curam, curah hujan sangat tinggi dan kurangnya tutupan tanaman hutan, salah satunya di lahan Perhutanan Sosial di Desa Mendelem. Penelitian ini bertujuan mengidentifikasi karakteristik internal petani sehubungan dengan sosial ekonomi, mendeskripsikan persepsi dari berbagai pihak terkait pengelolaan lahan yang mendukung konservasi tanah dan air, dan menyusun strategi yang dapat membantu meningkatkan produktivitas dan kelestarian lingkungan di lahan Perhutanan Sosial. Metode yang dilakukan adalah analisis kualitatif deskriptif dan analisis SWOT. Hasil penelitian menunjukkan terdapat 7 kekuatan, 13 kelemahan, 4 peluang, dan 5 ancaman, sehingga menghasilkan 5 strategi SO, 8 strategi WO, 3 strategi ST, dan 4 strategi WT., Land management that is in line with soil and water conservation efforts must be carried out to optimize social and economic values while maintaining ecological values to remain sustainable. Especially on land with steep slopes, very high rainfall, and on forest plant cover, one of which is in a Social Forestry, Mendelem Village. This study aims to identify the internal characteristics of farmers concerning socioeconomic, describe the perceptions of various parties related to land management that supports soil and water conservation, and arrange strategies that can help to increase productivity and realize environmental sustainability in Social Forestry Land. The method used was the descriptive qualitative analysis and SWOT analysis. The results showed 7 strengths, 13 weaknesses, 4 opportunities, and 5 threats, resulting in 5 SO strategies, 8 WO strategies, 3 ST strategies, and 4 WT strategies.

Judul: The Contribution of Social Forestry to the Income of Communities Around Forest Farmers in KPH Purwakarta
Abstrak: Berbagai permasalahan kehutanan yang terus terjadi di Indonesia menuntut perlunya solusi konkrit dalam mencegah degradasi dan deforestasi. Perhutanan Sosial hadir sebagi sebuah solusi untuk dapat menciptakan hutan yang lestari dan masyarakat yang sejahtera. Penelitian ini bertujuan menganalisis perkembangan program Perhutanan Sosial dan seberapa besar kontribusi yang diberikan terhadap pendapatan petani di wilayah KPH Purwakarta. Data dikumpulkan menggunakan metode wawancara kepada 40 orang petani yang tergabung dalam Lembaga Masyarakat Desa Hutan Bambu Jaya yang mendapatkan izin Perhutanan Sosial melalui Pengakuan dan Perlindungan Kemitraan Kehutanan (Kulin KK). Hasil penelitian menunjukkan bahwa kontribusi Perhutanan Sosial terhadap pendapatan rumah tangga petani LMDH Bambu Jaya yaitu sebesar 11,85%, hasil analisis faktor menunjukkan bahwa faktor yang memengaruhi pendapatan petani LMDH Bambu Jaya adalah luas lahan, dan tingkat kesejahteraan petani Perhutanan Sosial LMDH Bambu Jaya berada pada tingkat kesejahteraan sedang dan cukup hidup layak., Various forestry problems that continue to occur in Indonesia require the need for concrete solutions to prevent degradation and deforestation.

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.
