Judul: Potensi Bahaya di Kawasan Wisata Gunung Bromo, Resort Tengger Laut Pasir, Taman Nasional Bromo Tengger Semeru, Jawa Timur
Abstrak: Taman Nasional Bromo Tengger Semeru merupakan kawasan konservasi di Indonesia yang memiliki fenomena alam unik berupa laut pasir seluas 5.250 hektar dan gunung api bromo yang berada dalam Kawasan Wisata Gunung Bromo (KWGB). Gunung Bromo merupakan gunung berapi yang memiliki sejarah panjang dalam proses pembentukan dan perannya dalam kehidupan spiritual masyarakat Tengger. Masalah keselamatan dan keamanan sangat penting dalam kegitan wisata. Ancaman letusan gunung api, kecelakaan akibat topografi kawasan, kondisi cuaca, akibat faktor manusia, maupun dari faktor alam lain harus menjadi perhatian pengelola. Mengingat hal-hal tersebut maka dilakukan penelitian terhadap potensi bahaya yang mungkin terjadi dalam pemanfaatan KWGB sebagai objek wisata alam sebagai masukan bagi pengelola, masyarkat dan wisata agar bahaya yang mungkin terjadi dapat diketahui serta menjadi persiapan pengelola dalam manajemen bahaya yang akan dilakukan. Peneliitian dilaksanakan di Resort Tengger Laut Pasir TNBTS, Jawa Timur pada tanggal 6 Septemer - 22 November 2006. Teknik pengumpulan data dilakukan melalui wawancara langsung di lapangan dengan pengukuran kadar gas H2S, pengukuran suhu harian dan pengukuran jumlah gempa tremor vulkanik

Judul: Identifikasi Gangguan dan Kerusakan Flora dan Fauna di Kawasan Wisata Gunung Bromo Taman Nasional Gunung Bromo Jawa Timur
Abstrak: Bromo Tengger Semeru National Park (TNBTS) is a conservation area which has tourism object potential. One of tourism object that owned by area TNBTS and has the unique natural phenomenon is Gunung Bromo, which is encircled by sand sea, found on Tengger Laut Pasir Resort. The visitors in Bromo Mountain Tourism Area consist of various age level, most visitors don't know clearly th efunction of national park, so that seldom their activity generate damage at environment, especially flora and fauna. This research's purpose is for identifiying and evaluating the influence of tourism activity to flora and fauna in Bromo Mountain Tourism Area. Perception result in every tourism trail shown that there're happened some damages to some species of flora and some dirturbances of fauna. These disturbance and damage weren't only because of visitor but also by the society. The result of disturbance and damage identification to flora and fauna that caused by tourism activity are fracturing of branch, combustion, tannery, vandalism, throwing, garbage and hunt. Tourism activities that causing the disturbance and damage of flora and fauan are tracking, camping, hiking, cultural tourism, sunrise seeing, picnic, agrotourism and sight seeing. The result of disturbance and damage identification to flora and fauna that caused by society actibity are wood cutting, combusting and hunt. Society activities that causing the disturbance and damage of flora and fauna are seeking of firewood, seeking of cattle's food and accomplishment of food requirement

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.
