Judul: Bentuk dan Tingkat Partisipasi Stakeholders dalam Pengelolaan Cagar Biosfer Giam Siak Kecil-Bukit Batu (CB-GSK-BB), Provinsi Riau.
Abstrak: Giam Siak Kecil-Bukit Batu Biosphere Reserve (GSK-BB-BR) represents the tropical peat swamp forest Sumatera region that located in Bengkalis and Siak Regencies, Province of Riau. Giam Siak Kecil Bukit Batu Biosphere Reserve (GSK-BB-BR) was initiated by private sector, Sinarmas Forestry and supported by The Hall of Natural Resources Conservation (BBKSDA) Riau, Government of Riau Province and Indonesian Institute of Sciences (LIPI). Proposed Management Plan GSK-BB-BR 2009-2013 intended to give information based on the principle of multistakeholders management or collaborative management. Stakeholders participation is determiner components in collaborative management. The aims of this research were identification and analysis of the stakeholders interest and power in the management of GSK-BB-BR, classification of the stakeholders in the management of GSK-BB BR and identification of the stakeholders model and participation level in the management of GSK-BB-BR. The research was conducted in GSK-BB-BR, Province of Riau on July until September 2011. Materials were collected by indepth interview to key informan from stakeholders, selected by purposive sampling that considered their role in the management GSK-BB-BR and their knowledge about the research topic. Generally the interest of stakeholders are synergy with the function of ecosystems and the aim of the management in GSK-BB-BR. The results of identification are 31 stakeholders of GSK-BB-BR. Most of stakeholders are participate at level of partnership except the local community, still at level of information.

Judul: Penerapan Best Management Practices dalam Mitigasi Konflik Manusia-Satwa Liar di Giam Siak Kecil Bukit Batu, Riau
Abstrak: The existence of the Bukit Batu Giam Siak Kecil Biosphere Reserve (GSKBB) is one of the key habitat ecosystems of animals such as elephants and tigers. The manager who controls and utilizes land in the GSKBB Biosphere Reserve buffer zone area is a forestry business permit holder company, in this case managed by Industrial Plantation Forest concession holders who are APP Sinarmas wood suppliers with an area in the buffer zone of 222 426 ha. Most of these areas are home to key wildlife species such as tigers and elephants, as well as a source of food and water for prey habitat such as deer, wild boar, etc. This study aims to: (1) identify the ecological, economic, social and institutional aspects of the efforts to mitigate human and wildlife conflicts that have been carried out by the company, (2) determine the number of wild animals that use the concession area and the extent of the concession area used by wildlife, and (3) developing ideal human-wildlife conflict mitigation strategies from the economic, ecological and social sectors. This research is located in five concessions of APP Sinarmas's timber management unit, PT. Arara Abadi District Duri I, PT. Arara Abadi District Duri II, PT. Sekato Pratama Makmur and PT. Bukit Batu Hutani Alam. These five companies are in the buffer zone of the GSKBB Biosphere Reserve. This study involved 100 respondents from the community and 35 respondents from the company. All respondent data will be analyzed descriptively. Then the data collection of various other resources (carrying capacity of vegetation, water sources, prey animals, etc.) is carried out to complete the analysis related to ecological aspects, economic aspects and social aspects. The data collection of other resources such as elephant populations, tiger populations, and prey animals that enter the area using library data that has been done by companies and other library sources. The analytical method used is the Multi Dimension Scaling (MDS) method to determine the level of sustainability of human and wildlife conflict mitigation efforts. The results of this study in the form of recommendations for the company for an ideal management strategy in efforts to mitigate human and wildlife conflicts that are effective and efficient in accordance with the principles of Best Management Practices. The expected impact on this research is the company's activity continues to run and wildlife conservation, especially elephants and tigers is maintained., Keberadaan Cagar Biosfer Giam Siak Kecil Bukit Batu (GSKBB) merupakan salah satu ekosistem habitat satwa kunci seperti gajah dan harimau. Pihak pengelola yang menguasai dan memanfaatkan lahan di area zona penyangga Cagar Biosfer GSKBB adalah perusahan pemegang ijin usaha kehutanan yang dalam hal ini dikelola oleh pemegang konsesi Hutan Tanaman Industri yang menjadi pemasok kayu APP Sinarmas dengan luas pada zona penyangga yaitu 222 426 ha, sebagian besar wilayah ini merupakan salah satu wilayah jelajah satwa kunci seperti harimau dan gajah, sekaligus sebagai sumber pakan dan air bagi habitat satwa mangsa seperti rusa, babi hutan, dll. Penelitian ini bertujuan untuk: (1) mengidentifiaksi aspek ekologi, ekonomi, sosial serta aspek kelembagaan dari upaya mitigasi konflik manusia dan satwa liar

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.
