Judul: Partisipasi Masyarakat dan Strategi Pengembangan Ekowisata di Seksi PTN Wilayah I Cibodas, Taman Nasional Gunung Gede Pangrango.
Abstrak: Keberadaan Taman Nasional Gunung Gede Pangrango yang berbatasan langsung dengan pemukiman masyarakat menimbulkan adanya interaksi antara kawasan dengan masyarakat sekitar. Masyarakat dapat memanfaatkan kawasan TNGGP secara langsung tanpa merusak kawasan salah satunya melalui kegiatan pengembangan ekowisata. Pengembangan ekowisata di TNGGP akan berkembang kearah yang lebih baik apabila masyarakat sekitarnya mampu mengambil kesempatan untuk terlibat aktif dalam kegiatan pengembangan ekowisata. Penelitian ini bertujuan untuk mengukur persepsi dan partisipasi masyarakat serta menyusun strategi peningkatan partisipasi masyarakat terhadap pengembangan ekowisata di Taman Nasional Gunung Gede Pangrango. Metode yang digunakan yaitu observasi lapang, wawancara, kuesioner, studi pustaka dan pemilihan responden yang dilakukan secara simple random sampling. Masyarakat merasa bahwa ekowisata memiliki manfaat untuk kesejahteraan masyarakat namun belum sepenuhnya memberi dukungan dalam berpartisipasi terhadap pengembangan ekowisata. Partisipasi masyarakat dalam pengembangan ekowisata tertinggi berada dalam tahap menikmati hasil. Pada tahap perencanaan, pelaksaan dan evaluasi, partisipasi masyarakat masih perlu ditingkatkan. Strategi peningkatan partisipasi masyarakat menggunakan strategi SO yaitu menggunakan kekuatan untuk memanfaatkan peluang.

Judul: Peran Stakeholders dalam Pengembangan Ekowisata di Taman Nasional Gunung Gede Pangrango.
Abstrak: Taman Nasional Gunung Gede Pangrango merupakan Taman Nasional percontohan di Indonesia dengan potensi wisata yang masih dapat dimaksimalkan, dengan melibatkan stakeholders. Kepentingan dan pengaruh setiap stakeholders perlu diketahui untuk mengelompokkan stakeholders menjadi subject, key player, contextsetter, dan crowd, dan hasil tersebut disesuaikan dengan kebutuhan setiap stakeholders untuk merumuskan peranan stakeholders dalam pengembangan ekowisata di TNGGP. Tujuan penelitian yaitu mengidentifikasi stakeholders, menganalisis kebutuhan stakeholders, dan merumuskan peranan dan strategi partisipasi stakeholders. Metode pengumpulan data dengan wawancara, observasi lapang, dan studi pustaka. Stakeholders TNGGP berjumlah 26 dan dikelompokkan pada pemerintah pusat dan daerah, swasta, dan masyarakat. Informasi, koordinasi, dan kolaborasi merupakan poin penting yang perlu dimainkan oleh stakeholders key player.

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
