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: Pemanfaatan Sumberdaya Hutan di Taman Nasional Bromo Tengger Semeru oleh Masyarakat Desa Ranu Pani.
Abstrak: Desa Ranu Pani merupakan salah satu desa enclave Taman Nasional Bromo Tengger Semeru. Masyarakat yang berada di Desa Ranu Pani memanfaatkan sumberdaya hutan sebagai kebutuhan sehari-hari. Pemanfaatan sumberdaya hutan ini dihadapkan kepada kondisi bahwa Taman Nasional Bromo Tengger Semeru merupakan kawasan konservasi yang pemanfaatannya dibatasi oleh peraturan yang berlaku. Penelitian dilaksanakan di Desa Ranu Pani pada bulan Februari-Maret 2014. Tujuan dari penelitian adalah untuk mengidentifikasi potensi, pola pemanfaatan dan menilai sumberdaya hutan yang dimanfaatkan oleh masyarakat Desa Ranu Pani. Hasil survey dan wawancara diketahui sebanyak 38 jenis flora dan 27 jenis satwaliar. Pemanfaatan terbagi ke dalam pemanfaatan tumbuhan pangan, peliharaan, tumbuhan obat, tumbuhan untuk upacara adat, kayu bakar dan tumbuhan untuk pakan ternak. Pola pemanfaatan yang dilakukan masyarakat Desa Ranu Pani sudah mulai berubah dari pemanfaatan tradisional yang hanya memanfaatkan sumberdaya hutan untuk kebutuhan pribadi dan adat, mulai berubah ke arah “menjual” sumberdaya hutan tersebut. Pemanfaatan yang besar terhadap sumberdaya hutan baik itu flora maupun fauna oleh masyarakat Desa Ranu Pani akan menyebabkan kerusakan dan kelangkaan terhadap sumberdaya hutan yang ada. Nilai dari pemanfaatan sumberdaya hutan baik itu flora maupun fauna oleh masyarakat Desa Ranu Pani sebesar Rp. 1.115.492.000,00 per tahun.

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.
