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.

Abstrak: Eco-sport tourism merupakan aktivitas yang terintegrasi antara ekowisata dengan olahraga. Kebutuhan manusia berwisata untuk menyegarkan kembali jiwa dan pikiran sama pentingnya dengan kebutuhan untuk menyehatkan kondisi fisik melalui aktivitas olahraga. Perpaduan tersebut menjadikan eco-sport tourism sebagai alternatif kegiatan wisata yang layak dipertimbangkan. Taman Nasional Gunung Gede Pangrango (TNGGP) sebagai kawasan konservasi menyediakan beranekaragam sumberdaya yang potensial. Sumberdaya tersebut dapat digunakan sebagai daya tarik wisata terhadap aktivitas eco-sport tourism yang meliputi tiga klasifikasi yaitu active sport tourism, sport event tourism, dan nostalgia sport tourism. Keberadaan potensi sumberdaya di kawasan konservasi menjadi penting untuk diperhatikan sehingga strategi pengembangan eco-sport tourism harus berlandaskan pada pedoman pembangunan pariwisata berkelanjutan. Penelitian bertujuan untuk (1) menganalisis potensi eco-sport tourism di TNGGP untuk jenis kegiatan active sport tourism, sport event tourism dan nostalgia sport tourism, (2) menganalisis permintaan eco-sport tourism di TNGGP agar diperoleh motivasi dan persepsi wisatawan secara terperinci ketika melakukan suatu aktivitas olahraga beserta ekowisata, (3) menganalisis nilai ekonomi eco-sport tourism di TNGGP untuk mengetahui proyeksi peluang ekonomi yang dihasilkan dari suatu aktivitas olahraga beserta ekowisata yang dilakukan di kawasan konservasi, serta (4) menyusun strategi pengembangan eco-sport tourism di TNGGP secara terintegrasi antara aktivitas olahraga dan ekowisata sebagai upaya pembangunan pariwisata yang berkelanjutan. Penelitian dilakukan pada bulan Maret-Juli 2022 di Taman Nasional Gunung Gede Pangrango, Provinsi Jawa Barat. Tahap dalam analisis data dilakukan secara deskriptif kualitatif dan kuantitatif. Strategi pengembangan eco-sport tourism dirumuskan dengan metode SWOT. Hasil penelitian menunjukkan ketersediaan potensi sumberdaya wisata di TNGGP meliputi air terjun, bumi perkemahan, danau atau telaga, fenomena alam, suspension bridge, jalur bird watching serta pusat pendidikan konservasi.

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
