Judul: Perubahan struktur agraria dan implikasinya terhadap gerakan petani Pedesaan (analisa karakter forum Paguyuban Petani jasinga Pasca Ppan)
Abstrak: Masyarakat Desa Curug dan Desa Tegal Wangi mengalami kerugian pasca hilangnya lahan garapan. Kerugian yang dialami berupa pengurangan luas penguasaan lahan dan perubahan tingkat pendapatan. Respon yang dilakukan oleh masyarakat di dua desa tersebut adalah dengan membentuk organisasi Forum Paguyuban Petani Jasinga. Tujuan penelitian ini adalah untuk menganalisis perubahan struktur agraria dan pengaruhnya terhadap karakter gerakan petani. Hasil penelitian menunjukkan tidak terdapat pengaruh antara perubahan status sosial ekonomi terhadap dimensi gerakan petani. Di sisi lain, dimensi gerakan petani memberikan pengaruh terhadap karakter gerakan petani., Curug and Tegal Wangi community are facing the problem related to the land occupation. Two aspects which changed after the decrease of land occupation are the decrease of land tenure and income level. The emerging of Forum Paguyuban Petani Jasinga is a part of their strategy to over come the problem above. This study aims to analyze the influence of agrarian structure change to the character of organization. Result of this study shows there is no influence of change of social economic status to dimensions movement of farmers. On the other side, the dimensions of movement of farmers had influence in the character of movement farmers.

Abstrak: Agrarian conflict occurs because of the different of interest between two or more actor to an agrarian source. Agrarian conflict which happen in Desa Sukamulya occurs because of the disagreement between the community and the representative of the state, Lanud Atang Sandjaya TNI-AU. Lanud Atang Sandjaya claims and take over the community’s land and make them have to fight back through the Paguyuban Petani movement. This movement’s goal is to return the land rights to the community. There are some factors that can make the Paguyuban Petani become a national issue; the leadership, the collectivism, and the activities of the Paguyuban Petani, and the support from other people.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
