Abstrak: Hadirnya seorang pemimpin pastinya diharapkan dapat menjadi seorang yang dapat mendorong masyarakat kearah yang lebih sejahtera. Peran pemimpin dapat dianalisis dari 3 kelompok yakni peran pemimpin secara motivator, Fasilitator, dan Mobilisator. Jika pemimpin telah mampu menjalankan ketiga peran pemimpin tersebut, diharapakan modal sosial juga terbentuk pada masyarakat, bentuk modal sosial yang terbentuk yakni bonding, briding dan linking. Penelitian ini mengkaji mengenai hubungan peran pemimpin informal, dengan terbentuknya modal sosial yang ada di masyarakat dengan menggunakan metode pendekatan kuantitatif dan kualitatif atau biasa disebut mix method. Pada metode pendekatan kuantitatif menggunakan wawancara terstruktur, sedangkan pada penelitian kualitatif menggunakan wawancara mendalam. Sampel penelitian dipilih dengan metode sensus, sementara informan dipilih berdasarkan pengalaman dan pengetahuan terkait peran pemimpin yang ada secara purposive sampling. Hasil penelitian menunjukkan bahwa tidak ada hubungan antara peran pemimpin informal dengan terbentuknya modal sosial yang ada di masyarakat. Secara kualitatif diketahui bahwa modal sosial terbentuk karena adanya beberapa faktor yakni : lingkungan yang homogen, ketergantungan ekonomi, kebutuhan ekonomi, tradisi dan budaya yang ada, kebutuhan bersama, partisipasi, serta keuntungan yang diperoleh., The presence of a leader is certainly expected to be someone who can push society towards a more prosperous direction. The role of the leader can be analyzed from 3 groups, namely the role of the leader as a motivator, facilitator and mobilizer. If the leader has been able to carry out the three leadership roles, it is hoped that social capital will also be formed in the community, the forms of social capital that are formed are bonding, briding and linking. This research will examine the relationship between the role of informal leaders and the formation of social capital in society by using quantitative and qualitative approaches or commonly called the mix method. The quantitative approach uses structured interviews, while the qualitative research uses in-depth interviews. The research sample will be selected using the census method, while the informants will be selected based on experience and knowledge regarding the role of existing leaders by purposive sampling. The research results show that there is no relationship between the role of informal leaders and the formation of social capital in society. Qualitatively, it is known that social capital is formed due to several factors, namely: a homogeneous environment, economic dependence, economic needs, existing traditions and culture, shared needs, participation, and profits obtained.

Judul: Modal Sosial dan Kepemimpinan dalam Mendorong Aksi Kolektif Masyarakat Sekitar Hutan (Kasus: KTHKm Mandiri, Kalibiru, Hargowilis, Kokap, Kulon Progo, Daerah Istimewa Yogyakarta)
Abstrak: Masyarakat sekitar hutan umumnya menggantungkan pemenuhan kebutuhan hidupnya pada hutan. Masyarakat yang dahulu dianggap sebagai penghambat, kini dianggap sebagai cara alternatif dalam pengelolaan hutan. Modal sosial dalam pengelolaan hutan menjadi hal yang penting untuk dianalisis karena pada umumnya masyarakat sekitar hutan memiliki keterbatasan modal fisik dan modal ekonomi. Namun, modal sosial yang kuat tidak selalu menunjukkan pengelolaan sumber daya alam yang berkelanjutan. Beberapa individu berpengaruh muncul dalam gerakan lokal. Oleh karena itu, penelitian ini bertujuan untuk menganalisis hubungan modal sosial dan kepemimpinan dalam membangun aksi kolektif pengelolaan sumber daya hutan. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif yang didukung metode kualitatif. Pendekatan kuantitatif menggunakan kuesioner, metode free recall pada analisis jaringan sosial, dan wawancara mendalam untuk memperoleh data kualitatif. Hasil penelitian menunjukkan terdapat hubungan yang signifikan antara modal sosial dan karakteristik kepemimpinan dengan hasil aksi kolektif pada KTHKm Mandiri. Modal sosial dan karakteristik kepemimpinan berpengaruh secara parsial maupun secara simultan dengan hasil aksi kolektif., The community around the forest generally depends on the fulfillment of their lives in the forest. People who were once considered inhibitors, are now considered an alternative way in forest management. Social capital in forest management is important to be analyzed because in general the community around the forest has limited physical capital and economic capital. However, strong social capital does not always show the management of sustainable natural resources. Some infuential individuals emerge in local movements. Therefore, this study aims to analyze the relationship of social capital and leadership in building collective actions for forest resource management. The method used in this study is a quantitative method supported by qualitative methods. Quantitative approach using questionnaires, free recall methods on social network analysis, and in-depth interviews to obtain qualitative data. The results showed a significant relationship between social capital and leadership characteristics with the results of collective action in forest farmer group Mandiri. Social capital and leadership characteristics are partially and simultaneously influence the results of collective action.

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.
