Judul: Status Populasi Penyu Hijau (Chelonia mydas, Linnaeus 1758) di Taman Pesisir Pantai Penyu Pangumbahan, Kabupaten Sukabumi, Jawa Barat.
Abstrak: The populations of green turtles in Indonesia tend to decline in linearly over the time that affects the sustainability of green turtle. The turtles beach of Pangumbahan consist of productive area for green turtles landing and nesting habitat. Research to assess the status of sea turtle population from the past few years was carried out using data from management and from field survey on the coast of Pangumbahan beach in March until April 2014. The purpose of this research is to study green turtles population change and the production of eggs from 2007-2013, and to assess threat to green turtles (biophysical properties of habitat, number of tourist, villas and the number of building), and to recommends management strategy for green turtles conservation. Social data was taken using purposive sampling methods and length of green turtles was taken using curve carapace line method. The frequency of green turtle landing in 2009 to 2013 is dominated un nested. There is a declining trend of number of green turtles that nest in 2007-2013. This has an impact to production of eggs and hatchlings which showed a decline. A decrease in the frequency of green turtles that landed in the beach might be caused by variation of nesting activity, the number of eggs, and hatching success. Another threat to the population of nesting green turtles changes in turtles habitat at Pangumbahan beach, the level of lighting of the beach, the increasing number of buildings villa, and social condition.

Judul: Karakteristik biofisik habitat peneluran penyu hijau (chelonia mydas L.) dan interaksinya dengan populasi penyu hijau yang bertelur di Pantai Pangumbahan. Kabupaten Sukabumi, Propinsi Jawa Barat
Abstrak: Tingkat eksploitasi yang tinggi dan intensif, ditambah dengan kerusakan habitat penyu hijau, menyebabkan populasinya menurun setiap tahun. Salah satu upaya yang diperlukan untuk mengurangi penurunan populasi penyu hijau adalah dengan melakukan pembinaan habitat peneluran. Pembinaan tersebut dapat berupa upaya mempertahankan faktor-faktor fisika dan biologi lingkungan yang dibutuhkan oleh penyu hijau untuk melakukan kegiatan bertelur, bereproduksi, dan mencari makan, serta melakukan kegiatan penangkaran terhadap telur-telur penyu hijau secara intensif FB University PERTANIAN PENDIDIKAN SN ARTEMEN TITU OR PERPUSTAKΛΑΝ Penelitian ini dilakukan di Pantai Pangumbahan, Kabupaten Sukabumi Jawa Barat selama bulan April-Mei 1998, yang bertujuan untuk mengenal lebih jauh karakteristik biofisik habitat peneluran penyu hijau, sebaran dan asosiasi habitat peneluran berdasarkan faktor fisik dan biologi lingkungan, serta mengetahui parameter fisik dan biologi habitat peneluran yang berperan penting dalam interaksinya dengan populasi penyu hijau yang bertelur...

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.
