Judul: Stakeholder Analysis in Conservation of Sentarum Lutung in Danau Sentarum National Park, West Kalimantan
Abstrak: Lutung sentarum (Presbytis chrysomelas cruciger) merupakan satwa endemik Danau Sentarum, namun populasinya menunjukkan kecenderungan yang menurun sehingga perlu adanya upaya konservasi. Pemangku kepentingan memiliki peran penting dalam upaya konservasi lutung sentarum. Penelitian ini bertujuan untuk mengklasifikasikan stakeholder menurut kepentingan dan pengaruhnya dalam upaya konservasi, menilai fokus stakeholder, serta menilai bentuk interaksi antar stakeholder. Penelitian dilaksanakan di Taman Nasional Danau Sentarum menggunakan metode wawancara, analisis pengaruh dan kepentingn serta analisis interaksi komunikasi. Hasil penelitian menunjukkan terdapat 33 stakeholder yang terlibat dalam konservasi lutung sentarum di TNDS. Stakeholder terbagi 4 stakeholder key player, 20 stakeholder sebagai subject dan 18 stakeholder sebagai crowd. Manajemen kolaborasi melibatkan seluruh stakeholder yang masuk dalam seluruh klasifikasi. Stakeholder key player memiliki peran yang sangat penting dalam mempengaruhi stakeholder lain melalui kegiatan sosialisasi serta meningkatkan peran melalui kegiatan pemberdayaan masyarakat. Hasil interaksi komunikasi menunjukkan IPB menjadi aktor central dalam jaringan berdasarkan kategori penilaian yaitu degree centralty, Closeness centrality, beetwenness centrality dan eigenvector centrality.

Judul: Management policy options of Danau Sentarum National Park West Kalimantan Province
Abstrak: Management of Danau Sentarum National Park (DSNP) is conducted through DSNP Unit. Until now, the management has not achieved the expected objectives, namely the preservation of the area and welfare of the community. This condition indicates the single management by the government is not able to achieve the management objectives. This study aims to formulate the policy options of DSNP management through economic, social and policy approaches, in order to obtain better policy options economically (knowledge of economy as well as benefits generated), socially (reducing conflicts, culturally appropriate), and policy (governance; efficient/effective, less cost). These goals will be achieved through several studies, namely: 1) suspecting benefits and total economic potential of DSNP; 3) analyzing the stakeholders in the management of DSNP; 3) outlining the government’s social capital and capabilities in the management of DSNP; and 4) analyzing policy of DSNP management. The research had been conducted in the area of DSNP in the West Kalimantan Province. The data was collected using the techniques of: 1) Document research, 2) interview, 3) direct observation. The number of community samples quota is 60 (sixty) households in each location (3 SPTN) which was determined by random sampling. To comply with information obtained from the respondents, interviews were conducted with key informants in each study site. As for other stakeholders, the interviews were carried out with a snowball method. The data were analyzed quantitatively (categorization) and qualitatively. There were many kind of benefits in DSNP with high economic value. The TEV of DSNP covers Rp 139 billion per year. This result when compared with the cost of managing DSNP that covered Rp 6.7 billion in 2010 shows that only 4.82 percent of the benefits generated. It means that DSNP as conservation area that have been considered as a cost center is not true. This potential economic value of DSNP could be real by implementing incentive mechanism in the management of DSNP, where for the current time the incentive mechanism that is likely to run is water for environmental service for households. Various benefits and the high economic value contained in DSNP attract various stakeholders to utilize and manage them. There are 18 (eighteen) stakeholders involved in the management of DSNP, consisting of government, community, Non-Governmental Organization (NGO) and research institution. Based on their influence and importance, the stakeholders serve as subjects, key players, context setter and crowd; and the relation among them is conflicts, complementary and cooperation. The existence of these various stakeholders brings along the consequence that the management conducted in DSNP needs to be changed from a single management by the government to management involving the stakeholders. The form of stakeholders’ involvement can be seen from social capital at the community level and capability of the government in managing DSNP. Social capital in the community within the area of DSNP which is assessed from trust, norms and social networks shows the strong/high of social capital of the community. Public trust to the role of community leaders in managing natural resources is very high, which indicates that more people obey what is commanded by their leader.

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.
