Judul: Strategi Taman Nasional Gunung Gede Pangrango (TNGGP) dalam Pengembangan Promosi Kegiatan Ekowisata
Abstrak: Mount Gede Pangrango National Park has a high potential ecotourism site to be promoted. In this case, promotion of ecotourism in Mount Gede Pangrango aims to attract both tourists and partners to devote in ecotourism activities. The purposes of this research are to evaluate recent strategies of ecotourism promotion and to map new strategies of Mount Gede Pangrango National Park in promoting ecotourism. The mapping of these promotion strategies is based on SWOT analysis. Ecotourism promotion in Mount Gede Pangrango National Park has acquired four components of promotion mix which are advertising, personal selling, public relation, and promotion selling, but has not used all promotion media and has not done promotions gradually. Promotion has not been effectively accepted by public. Data shows 71% visitors get information word of mouth, 14% from printed media, 11% from school/work place, and 4% from internet. The result of this SWOT analysis puts promotion in second quadrant, namely stability strategy. Stability strategy is consolidation strategy for reducing weaknesses and maintaining recent market. Stability aims to maintain such condition by using opportunities and restore weaknesses. This strategy leads to a project opening opportunities for private sectors to work on ecotourism, doing cooperation with airports and airlines services, tourism bureaus, mass media, hotels, and also uses an appropriate promotion media for introducing Mount Gede Pangrango National Park. Based on the exposed analysis, strategic ecotourism promotions can be conducted are : using the website of TNGGP by preparing interesting information, cooperation with tourism bureaus by setting or planning tourism packages, cooperation with airport, cooperation with mass media, doing direct mailing promotions, maintaining infrastructures which provides information on ecotourism, raising ticket’s prize, giving courses to human resources, developing new potential tourism sites.

Judul: Strategi Komunikasi Pemasaran pada Kawasan Ekowisata Berbasis Masyarakat
Abstrak: Ekowisata merupakan suatu konsep pariwisata yang mencerminkan wawasan lingkungan, mengikuti kaidah keseimbangan dan kelestarian lingkungan. Pengembangan ekowisata dapat meningkatkan kualitas hubungan antar manusia, meningkatkan kualitas hidup masyarakat setempat dan menjaga kualitas lingkungan. Pada saat ini pemerintah sedang menata sebuah konsep ekowisata baru, yakni ekowisata berbasis masyarakat dimana masyarakat berperan penuh dalam pengelolaan, pengambil keuntungan, serta akomodasi dan sarana dan prasarananya. Penelitian ini bertujuan menganalisis efektivitas komunikasi pemasaran yang sudah dilakukan oleh Taman Nasional Gunung Gede Pangrango (TNGGP) dan stakeholdernya. Stakeholder dalam hal ini yakni LSM, Pemerintah, dan juga pengunjung yang ikut memasarkan ekowisata di Taman Nasional Gunung Gede Pangrango (TNGGP). Penelitian ini juga bertujuan untuk merumuskan formulasi strategi komunikasi pemasaran yang cocok diterapkan di ekowisata berbasis masyarakat. Penelitian ini berlangsung selama empat bulan yang dilakukan di Taman Nasional Gunung Gede Pangrango. Metode penelitian ini menggunakan pendekatan kuantitatif yang didukung pendekatan kualitatif. Data primer diperoleh melalui wawancara mendalam dan kuesioner, sedangkan data sekunder diperoleh melalui Balai Besar Taman Nasional Gunung Gede Pangrango. Pemilihan responden dilakukan menggunakan teknik accidental sampling yakni pengunjung yang berada di tempat penelitian saat berlangsung. Pemilihan lokasi yakni di TNGGP dipilih secara purposive karena dianggap sesuai dengan tema yang dipilih. Terdapat dua variabel umum yang digunakan untuk menguji efektivitas komunikasi pemasaran untuk mempromosikan ekowisata berbasis masyarakat di Taman Nasinal Gunung Gede Pangrango, yaitu rancangan pesan berupa attention, need, satisfaction, visualization, dan action. Variabel kedua adalah ragam media penyampaian komunikasi pemasaran, berupa bauran promosi yakni periklanan (koran, majalah, website, dan billboard), promosi penjualan (pameran, potongan harga, dan hiburan), penjualan pribadi (presentasi penjualan dan promosi pameran) dan word of mouth. Berdasar hasil penelitian yang dilakukan, jika dilihat dari rancangan pesan, maka komunikasi pemasaran ekowisata berbasis masyarakat di Taman Nasional Gunung Gede Pangrango belum efektif, hal ini terlihat dari hasil uji rank Spearman yang menyatakan variabel rancangan pesan signifikan dengan efektivitas komunikasi pemasaran yang ada. Melihat hasil uji rank Spearman mengenai ragam media penyampaian, variabel ragam media belum terlihat efektif sehingga seluruh ragam media penyampaian yang telah dilakukan oleh pihak pengelola harus lebih ditingkatkan agar lebih optimal dalam penyampaiannya. Media tersebut adalah humas. Aksi jemput bola harus dilakukan Taman Nasional Gunung Gede Pangrango dalam membuat kolaborasi antar stakeholder dan LSM yang sudah berpengalaman dalam hal ekowisata dan pemasarannya, sehingga disarankan untuk dilakukan sesegera mungkin. Strategi komunikasi pemasaran yang cocok diterapkan yaitu usaha kerjasama antar kalangan swasta, LSM yang terkait, pemerintah kabupaten dan Dinas Kebudayaan dan Pariwisata. Tidak lupa pendistribusian alat komunikasi pemasaran seperti brosur, leaflet, dan booklet tentang ekowisata di kawasan Taman Nasional Gunung Gede Pangrango di tempat yang dianggap potensial. Ekowisata berbasis masyarakat masih baru dan masih perlu banyak perbaikan di segala lini tidak hanya dalam pemasarannya namun dalam sarana dan prasarana penunjang. Peranan stakeholder yang berperan dalam penyelenggaraan pemasaran ekowisata berbasis masyarakat di Taman Nasional Gunung Gede Pangrango sangat diharapkan dapat berkontribusi maksimal dalam pengelolaan ekowisata berbasis masyarakat.

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
