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: The Role of Leaders and the Succes of Tourism Village (Case: Kampung Tematik Mulyaharja, Bogor Selatan Subdistrict, Bogor City, West Java)
Abstrak: Desa-desa di Indonesia mulai memaksimalkan potensi pengembangan desa wisata. Salah satunya adalah Kampung Wisata Mulyaharja, Kecamatan Bogor Selatan, Kota Bogor, Jawa Barat. Kampung wisata ini termasuk dalam kategori desa wisata yang maju. Penelitian ini bertujuan untuk melihat hubungan peran pemimpin kelompok penggerak pariwisata dengan tingkat keberhasilan dari Kampung Wisata Tematik Mulyaharja. Penelitian ini berlokasi di Kampung Wisata Tematik Mulyaharja, Kelurahan Mulyaharja, Kecamatan Bogor Selatan, Kota Bogor, Jawa Barat. Penelitian ini menggunakan pendekatan kuantitatif dengan 31 responden yang berada di bawah pimpinan ketua Kompepar dan didukung oleh data kualitatif melalui wawancara mendalam. Analisis data kuantitatif menggunakan analisis korelasi Rank Spearman dan data kualitatif dianalisis dengan mereduksi data dan penyajian data. Hasil dari penelitian ini menunjukkan bahwa ada hubungan yang signifikan antara peran ketua Kompepar dengan tingkat keberhasilan Kampung Wisata Tematik Mulyaharja. Namun, adanya korelasi yang signifikan antara peran mobilisasi dan tingkat sukses kampung wisata dapat menimbulkan risiko bagi keberlanjutan kampung wisata. Oleh karena itu, diperlukan peran kepemimpinan yang memprioritaskan keberlanjutan. Salah satu contohnya adalah penerapan Kepemimpinan Hijau., Villages in Indonesia are starting to maximize the potential for developing tourist villages. One of them is the Mulyaharja Tourist Village, South Bogor District, Bogor City, West Java. This tourist village falls into the category of advanced tourist villages. This study aims to look at the relationship between the role of tourism group leaders and the level of success of the Mulyaharja Thematic Tourist Village. This research is located in the Mulyaharja Thematic Tourist Village, Mulyaharja Village, South Bogor District, Bogor City, West Java. This study uses a quantitative approach with 31 respondents who are under the leadership of the Kompepar chairman and is supported by qualitative data through in-depth interviews. Quantitative data analysis uses Spearman Rank correlation analysis and qualitative data is analyzed by reducing data and presenting data. The results of this study indicate that there is a significant relationship between the role of the Kompepar chairman and the level of success of the Mulyaharja Thematic Tourist Village. However, the significant correlation between the role of mobilization and the success level of the tourist village can pose a risk to the sustainability of the tourist village.

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.
