Judul: Studi Konservasi Sumberdaya Alam Hayati pada Masyarakat Tengger di Resort Ranu Pani, Taman Nasional Bromo Tengger Semeru
Abstrak: Ranu Pani village is an enclave village located in a area Ranu Pani Resort, Bromo Tengger Semeru National Park. Purpose of this study was to access the understanding and motivation of Tengger society, the level of economic dependency, and examines the real action of conservation. Methods in use begins with a literature study, field observation, and questionnaires. The trust believed that the forest is the system of life that must be preserved for the sake of happiness the offspring, forming positiveness on Tengger society to maintain the forest in order to preservein an hereditary manner, utilization done very limited only adoption of kindling the trees that is dead and retrieval grass for cattle course. The economic society derived from the results of the field so as not to be depended from biological resources in the forest. Ranu Pani village society sometimes actively in conservation activities through planting, forest ares extinguish the blaze, and joined in the conservation cadre society ang public patner of rangers. Various counseling who regularly performed by the management of Ranu Pani Resort, capable of being creates understanding conservation for Ranu Pani society so take care of security of the area an understand the established rules.

Judul: Dinamika Kearifan Tradisional Masyarakat Desa Ranu Pane dalam Pemanfaatan Sumberdaya Hayati di Taman Nasional Bromo Tengger semeru
Abstrak: Desa Ranu Pane merupakan wilayah enclave TNBTS yang terletak pada ketinggian 2200 mdpl. Desa Ranu Pane memiliki luas 300 ha yang terbagi ke dalam dua dukuh yaitu Mbedog Asu (Sidodadi) dan Besaran. Pada kawasan ini terdapat zona pemanfaatan tradisional yang dapat digunakan oleh masyarakat dalam memanfaatkan sumberdaya hutan TNBTS. Metode yang digunakan di dalam pengumpulan data adalah metode FGD (Foccus Group Discussion), wawancara dan kuesioner dalam bentuk close ended. Kearifan lokal mengenai pemanfaatan flora dan fauna sudah mulai tergeser. Pemanfaatan flora untuk saat ini masih dimanfaatkan walaupun tidak seintensif dulu seperti pemanfaatan tumbuhan obat, tumbuhan pangan dan bahan sajen. Pemanfaatan fauna sudah tidak lagi dimanfaatkan oleh masyarakat Suku Tengger. Pergeseran ini terjadi karena beberapa faktor yaitu larangan dari pihak taman nasional, sumberdaya alam yang tersedia dan tidak adanya kemauan dari generasi muda untuk memepelajari kearifan lokal.

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.
