Judul: The Dynamics of Farmer Groups in the Development of Private Forest in Serang District
Abstrak: Dinamika/perkembangan pengusahaan hutan rakyat (HR) tidak terlepas dari peran kelompok tani. Kelompok tani selain tempat berkumpul para petani juga sebagai sarana bertukar informasi dan pengalaman mengenai teknik pengelolaan HR. Tujuan penelitian: menganalisis organisasi dan aturan main, menganalisis hubungan perkembangan kelompok tani dengan perkembangan HR, dan menganalisis pengaruh faktor langsung dan tidak langsung terhadap kinerja kelompok. Penelitian ini merupakan penelitian studi kasus, dilakukan pada kelompok tani Suka Maju di Desa Sindang Karya Kabupaten Serang. Pengumpulan data dilakukan secara sensus dengan cara wawancara mendalam kepada seluruh anggota kelompok tani, observasi, survei, dan studi literatur untuk mendapatkan data sekunder. Analisis data dilakukan berdasarkan analisis deskritif dan kuantitatif. Tujuan pertama dianalisis dengan melakukan penelusuran organisasi kelompok tani sejak awal berdiri hingga penelitian dilaksanakan. Tujuan kedua dianalisis dengan cara mendeskripsikan secara jelas/mendalam perkembangan kelompok tani dan perkembangan HR yang dikelola kelompok tani. Tujuan ketiga dianalisis dengan menggunakan analisis jalur (path analysis)., Farmer Groups (FGs) have played an important role in the management of Private Forest (PF). In addition to a gathering place, an FG is also a means of exchanging information and experiences to manage their PFs. The objectives of this research are to analyze: (1) the organization and rules of FG (2) the relationship between the development of FG and the development of PF; and (3) direct and indirect factors influencing the group’s performance. This research is a case study involving “Suka Maju” group of farmers of Sindang Karya Village, Serang District. The research was conducted using survey, in-depth interviews, observations, and literature reviews. The respondents of this research are all members of the FG. Survey, in-depth interviews, and observations were used to collect primary data. Literature study was used to collect secondary data. Data was analysed using descriptive and quantitative techniques. The first objective was analyzed by tracing the organization of farmer groups since 2011 to the time when the research was carried out. The second objective was analyzed by describing the development of FG and the development of PF. The third objective was analyzed using path technique.

Judul: Pengelolaan Hutan Rakyat dan Dinamika Kelompok Tani Hutan (Kasus pada Kelompok Tani Hutan di Desa Sidamulih, Kecamatan Pamarican, Kabupaten Ciamis)
Abstrak: At this time the community forest has been proved to give great benefit for owner, society, and environment (Darusman and Hardjanto 2006). One of the factors that determine the successness of community forest management is the establishment of institutional Forest Farmers Group (FFG) (Diniyati 2003). By the process, it is expected to have a significant and positive relationship with the community forest management. This research aimed to describe community forest management and the dynamic of FFG Girimukti, Sidamulih Village, Pamarican Sub District, Ciamis Regency for community forest management. The population of this study was the members of FFG Girimukti. The method for selecting of respondents was purposive sampling. Community forest management activities that were carried out at FFG Girimukti will be described as follows: Sub system of production included, land preparation, seed preparation, planting, plant maintenance, and harvesting. Sub system of yield processing was done by cooperation with some of the sawmills in the Sidamulih Village. Sub system of yield marketing was consisted of timber that being sold by members to the sawmill or to the middlemen and non timber forest products that being sold by members to the middlemen. The dynamic of FFG Girimukti can be viewed by 8 elements of group dynamic, it will be described as follows: The group has had purposes that tobe written and understood by members. Each member has received and understood him/her role/task. The group has done its function of assignment that was, to give satisfaction/convenience for members of community forest management. Members were participated in the determination of the common interest like the planning group activities. In the group cohesiveness, members have had a sense of loyalty to the group leader. They built a fine atmosphere inside the group, it’s proved by the group meetings always take place smoothly. The pressure came from outside of the group, such as from government of Ciamis District by BP3K Pamarican. In the group effectiveness, the level of the members participation in the group activities was high which that was characterized by a majority of respondents participated in routine activities of the group or incidental one. Based on the result of the correlation test, the dynamic of FFG Girimukti has a real and positive relationship with its community forest management.

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.
