Judul: Studi Permintaan Rekreasi dan Strategi Pengembangan Ekowisata Spiritual di Taman Nasional Ujung Kulon
Abstrak: Spiritual tourism is a growing tourism phenomenon at Ujung Kulon National Park. Identification of demand and its potential impacts become important to define eco-spiritual tourism development strategy for the ecologically high-sensitive national park. Study on pilgrimage site visitors within the park shows that they were motivated to know history, know ancestors, and seek help for career and business excellence; and also have minimum concern on tourism facilities and services. While, study on local people and park manager shows that spiritual tourism activities are tought to have moderate impact on economical and socio-cultural aspect of local people, as well as its relation on park management policy. The concept of eco-geo-spiritual-tourism is proposed from the study to maintain optimum balanced point between visitor needs, benefit for local society and the park sustainability.

Judul: Study of Tourism Management in Protected Area (Case Study: Ujung Kulon National Park, Pandeglang Regency, Banten Province)
Abstrak: Taman Nasional mempunyai fllngsi melilldllllgi keanekaragaman hayati dan ekosistem yang menjadi nilai pentingnya, dan jnga berfimgsi untuk peudidikan, penelitiall dan wisata (pemanfaatan secara lestari). Untuk memenuhi kedna fimgsi tersebllt, taman nasional dihadapkan pada tugas pengelolaan yang berat. Namun demikian, banyak yang meyakini bahwa kegiatan wisata di kawasan konservasi dapat menjadi alternatif untuk rnenciptakan mekanisme pendanaan pengelolaan karena bersifat non ekstraktif, serta dapat meningkatkan apresiasi masyarakat luas terhadap nilai penting taman nasional. Peuelitian ini dilakukan untuk menganaiisis kondisi pengelolaan Taman Nasionai Ujung Kulon dan mengkaji alternatif pengelolaan wisata dengan fokus identifikasi produk wisata pesisir dan bahari menggunakan pendekatan Visitor E-cperience and Resource Protection (VERP) dan Zona Kesempatan Rekreasi (ROS : Recreation Opportunity Speclnlm) serta PIOSes yang partisipatif., The biodiversity protection is critically important function, not only for protected areas bnt also have function to ensure adequate and appropriate access for tourism and recreational purposes. People believe that tourism in protected area could be an option to solve management problems and to raise local community appreciation. Unfortunately, it is not the case in Ujung Kulon National Park. The research is dedicated to analyze existing Ujung Kulon tourism management and try to resolve options for tourism management plan, focusing in tourism product identification using VERP (Visitor Experience and Resource Protection) framework and ROS (Recreation Opportunity Spectrum).

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
