Judul: Studi pasar burung di sekitar taman nasional Gunung Gede Pangrango
Abstrak: Pasar burung merupakan tempat dikumpulkannya burung-burung untuk diperdagangkan. Terdapat kemungkinan jenis-jenis yang diperdagangkan di pasar burung berasal dari kawasan konservasi. Kemungkinan ini akan sangat besar apabila lokasi pasar burung berdekatan dengan suatu kawasan konservasi salah satu contoh adalah Taman Nasional Gunung Gede Pangrango (TNGP).

Judul: Perencanaan dan pengelolaan pengembangan taman nasional gunung gede-pangrango
Abstrak: Tujuan penelitian ini adalah untuk membuat suatu perencanaan dan pengelolaan pengembangan Taman Nasional Gunung Gede Pangrango. Penelitian dibuat di kawasan Cagar Alam Cibodas, Cagar Alam Cimungkat, Taman Wisata Situ Gunung, areal Perum Perhutani dan desa-desa di sekeliling Taman Nasional yang diusulkan. Agar faktor-faktor biotik, abiotik dan ekosistem dapat dikelola secara lebih efektif untuk tujuan konservasi alam, ilmu pengetahuan, kebudayaan, rekreasi dan lingkungan hidup manusia dengan memperhatikan kondisi sosial ekonomi, masyarakat, kondisi pembinaan dan administrasi, areal-areal tersebut perlu dikelola menjadi satu unit yang disebut Taman Nasioanl. Areal Taman Nasional Gunung Gede-Pangrango yang diusulkan memiliki beberapa jenis ekosistem hutan submontane, pegunungan, hutan elfin, vegetasi pionir kawah gunung berapi, vegetasi padang rumput Alun-alun. Taman Nasional yang diusulkan memiliki flora khas yaitu Quercus spp, Anaphalis javanica, Isachne pengerangensis dan Engelhardtia spicata. Tumbuhan langka di dalam Taman Nasional antara lain ialah Tumbuhan parasitik Dendrophthoe magna Carex graeffeana. merupakan jenis pohon yang hanya terdapat di kawasan perlindungan G. Gede-Pangrango dan di G. Kinabalu, Sabah. Jenis anggrek Corybas mucronatus, Liparis bilobulata,. Pachycentriá varingiaefolia dan Malaxis sagittata merupakan jenis langka yang hanya terdapat di kawasan ini. Disamping flora khas dan langka Taman Nasional G. Gede-Pangrango juga mempunyai fauna menarik. Kera, lutung, babi dan leopards masih terdapat di hutan pegunungan ini. Anjing hutan (Cuon alpinus javanicus) dapat dianggap sebagai species yang langka. Mayoritas burung berada pada hutan tebal bagian bawah pegunungan. Burung betutut (Megalaema corvina), (M. hearicii) dan burung engkut-engkut gunung (M. armillaris) sering dijumpai pada bagian rendah pegunungan. Yang menonjol pada pegunungan tinggi adalah burung anis gunung (Turdus poliocephalus). Burung elang (Falco peregrinus) dapat dijumpai dekat dinding-dinding kawah G. Gede. Tempat- tempat menarik yang dapat dikembangkan untuk tujuan wisata adalah air terjun di Cibeureum, danau Bira dan Rawa Gayonggong dekat Cibeureum, telaga air panas di Kandang Batu, padang rumput Alun-alun G. Gede, danau đi Taman Wisata Situ Gunung, Kawah Ratu dan Kawah Wadon di G. Gede dan Kandang Badak. Kegiatan rekreasi yang dapat dikembangkan ialah foto- grafi, seni lukis, berkemah dan berjalan kaki. dst. …

Judul: Algorithm Construction of HLI Hash Function
Abstrak: Cryptography is a study of mathematical techniques related to aspects of information security regarding on confidentiality, data integrity, entity authentication, and data origin authentication. Data integrity is a service, which is associated with the conversion of data carried out by unauthorized parties. To maintain data integrity, one can use hash functions. An hash function is a computationally efficient function to map an arbitrary length bitstring to a fixed length bitstring called as hash value. The use of hash function in maintaining the information integrity and authentication is in digital signatures, virus protection, and software distribution. Illustration of the hash function in the integrity and authentication of information that is emailed as follow. The sender sends the information and hash value to the recipient. If the hash value of the information is equal to the hash value that is sent by the sender, then information has not been changed. Otherwise the information has been changed. An hash function has two properties, one way and collision resistance. An hash function is called one way if it is computationally infeasible to find any input such that when given any hash value . Meanwhile an hash function is called collision resistant if it is computationally infeasible to find any two inputs where such that . The purpose of this study is to construct a HLI hash function algorithm, to analyze the speed and security of the hash functions as a results of construction. Furthermore, it is to compare it with SWIFFT. Hash function is constructed based on the result of algebraic operations on modular polynomial ringwith . Modular polynomial ring noted as is a set of all polynomials of degree at most with coefficients in . can be represented as a set of integer vector of modulo in dimension . So, it is simple to implement in a computer. In vector operations, is lattice . Furthermore, alattice that is defined from certain polynomial ring is called ideal lattice. HLI hash function is consists of addition and multiplication algorithm in the ring. Addition algorithm consists of sumation operations of modulo and multiplication consists of multiplication operations of modulo . Generally, algorithm of HLI hash function consists of multiplication operations of modulo and addition operations of modulo . However, if the input is binary number then multiplication algorithm only consists of multiplication operation of modulo , so algorithm of HLI hash function consists of multiplication operations of modulo and addtion operations of modulo . An hash function is secured if it has two properties, i.e., one way and collision resistance. HLI hash function hash is one way, it is following the proof of Micciancio. It is has collision resistant because of polynomial is irreducible over and monic. Moreover, it is proved that for every unit vector , the vector is small vector. If the input of hash function is a binary number then HLI hash function only involves addition operations of modulo . So the time that used almost same with SWIFFT. The excellence of HLI hash function is the key size smaller than SWIFFT. This effect on
