Judul: Economic Value Estimation of Flora Diversity Potentially as Medicinal Plants in National Park of Mount Halimun Salak
Abstrak: Taman Nasional Gunung Halimun-Salak (TNGHS) merupakan salah satu Taman Nasional yang memiliki keanekaragaman flora yang tinggi yang berada di Provinsi Jawa Barat. Penelitian ini bertujuan untuk mengetahui jenis-jenis tanaman yang sudah dimanfaatkan oleh masyarakat Desa Malasari di Pengelolaan Taman Nasional Wilayah Cikaniki (PTNW Cikaniki), baik itu yang sudah dikomersialkan atau belum dikomersialkan, menghitung nilai ekonomi dari keanekaragaman flora yang berpotensi sebagai bahan baku obat di TNGHS, dan mengetahui stakeholder yang terkait dengan pengelolaan keanekaragaman flora yang berpotensi sebagai bahan baku obat di TNGHS. Metode harga pasar dan harga barang pengganti digunakan untuk mengetahui nilai ekonomi tanaman, dan snowball sampling untuk mengetahui stakeholder terkait dalam pengelolaan Berdasarkan hasil penelitian, terdapat 145 jenis tanaman yang memiliki manfaat obat, beberapa diantaranya sudah dikomersialkan diolah menjadi produk, 53,8% tanaman telah dikomersialkan dan belum dikomersialkan menghasilkan persentase 46,2%. Nilai keuntungan pengolahan tanaman obat berbentuk kapsul paling tinggi dimiliki oleh jahe merah dengan keuntungan Rp4.650.000 per 20 kilogram bahan baku segar, selain itu terdapat 5 stakeholder yang terkait dalam pengelolaan keanekaragaman flora berpotensi sebagai obat baik itu secara langsung maupun tidak langsung dengan stakeholder paling berpengaruh dan berkepentingan adalah TNGHS.

Judul: Analisis Stakeholders dan Ekonomi Pusat Konservasi Keanekaragaman Hayati (PKKH) Taman Nasional Gunung Halimun Salak (TNGHS) (Studi Kasus: Desa Puraseda dan Malasari, Kabupaten Bogor, Jawa Barat)
Abstrak: The high number of damaging activities by human threatened the sustainability of biodiversity and environment services. Therefore it is important to keep the sustainability of Halimun Salak National Park Forest by establishing the Center of Biodiversity Conservation (PKKH) as a long term plan program from TNGHS Office. The objectives of this research were to analyze stakeholders that related with the development of PKKH TNGHS area and to estimate the economic value from non-using of TNGHS. This study used Contingent Valuation Method, and Rank Spearman Test. The results showed that estimated of benefit value from TNGHS non-using forest for next 25 years was Rp 19.597.970.210,117/year. The stakeholders which are involved as key players are Malasari Village, PT. Aneka Tambang, Chevron, and TNGHS Office. The subject of stakeholders are Sustainable Management Group, Nanggung Subdistrict, and Citugu Conservation Village Model. Based on this research, it is important to continue this PKKH to keep the sustainability of biodiversity.

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.
