Judul: Kajian Pengelolaan Sumberdaya Alam Danau Situgunung untuk Pengembangan Ekowisata, di Taman Nasional Gunung Gede Pangrango
Abstrak: Danau Situgunung memiliki pesona alam yang dapat menjadi daya tarik wisata. Namun ada beberapa masalah yang timbul akibat dari pemanfaatan danau sebagai daerah wisata dan kurang optimalnya pengelolaan dalam pengembangan wisata perairan. Tujuan penelitian ini adalah mengidentifikasi potensi sumberdaya alam Danau Situgunung; menganalisis kesesuaian wisata dan daya dukung kawasan dalam pemanfaatan wisata perairan untuk pengelolaan dan pengembangan ekowisata; menganalisis pengelolaan wisata Danau Situgunung; dan menyusun strategi pengelolaan yang memperhatikan kelestarian lingkungan dan keberlanjutan pemanfaatan. Ruang lingkup penelitian ini dibatasi pada analisis faktor-faktor strategi internal dan eksternal serta formulasi strategi pengembangan ekowisata di Danau Situgunung. Penelitian ini dilakukan di Danau Situgunung Taman Nasional Gunung Gede Pangrango. Pengambilan data di lapangan dan data sekunder berlangsung dari bulan Januari 2010 hingga Mei 2010. Alat analisis yang digunakan adalah analisis kesesuaian wisata (IKW), analisis daya dukung kawasan (DDK), IFE (Internal Factor Evaluation), EFE (External Factor Evaluation), IE (Internal-External), SWOT (Strength, Weakness, Opportunities, Threats) dan QSPM (Quantitative Strategic Planning Matrix).

Judul: Analisis Stakeholder Destinasi Wisata Alam Situ Gunung Taman Nasional Gunung Gede Pangrango, Jawa Barat
Abstrak: Upaya pemanfaatan sumberdaya alam hayati beserta ekosistemnya di Taman Nasional Gunung Gede Pangrango (TNGGP) dilakukan dengan berbagai cara, salah satunya melalui kegiatan pariwisata yaitu pengembangan Kawasan Wisata Alam Situ Gunung (KWASG). Tujuan penelitian ini yaitu mengidentifikasi stakeholder, menentukan kategori stakeholder, dan menentukan tingkat partisipasi stakeholder dengan menggunakan kuesioner, wawancara, observasi, dan penelusuran dokumen. Data yangdiperoleh dianalisis dengan menggunakan matriks analisis stakeholder dan analisis tingkat partisipasi stakeholder. Stakeholder yang terlibat dalam pengembangan DWASG TNGGP berdasarkan nilai penting dan pengaruh terdiri atas 25 stakeholder yang dapat dikelompokkan kedalam instansi pemerintah pusat, instansi pemerintah daerah, badan usaha milik swasta, dan kelompok masyarakat. dengan klasifikasi yaitu key player sebanyak 8 stakeholder, subject sebanyak 9 stakeholder, context setter sebanyak 2 stakeholder, dan crowd sebanyak 6 stakeholder. Sebagian besar stakeholders berpartisipasi sampai pada tingkat informasi di setiap fungsi BBTNGGP. Akan tetapi berdasarkan analisis tingkat partisipasi stakeholder terdapat korelasi antara tingkat partisipasi dengan matriks stakeholder, yaitu bahwa semakin tinggi tingkat nilai penting dan pengaruh dalam suatu proyek atau kegiatan maka semakin banyak ruang partisipasi stakeholder dalam pengembanganDWASG. Pengembangan DWASG dapat ditingkatkan dengan mengintegrasikan peranan masing-masing stakeholder dengan cara membentuk Tim Koordinasi DWASG. Pembentukan Tim Koordinasi DWASG bertujuan untuk meningkatkan peranan stakeholder dalam manajemen kolaboratif pengembangan DWASG (inventarisasi, perencanaan, pelaksanaan, pemantauan dan evaluasi).

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
