Judul: Perencanaan Media Interpretasi di Kawasan Wisata Alam Situ Sangiang Taman Nasional Gunung Ciremai
Abstrak: Media interpretasi diperlukan untuk meningkatkan kepedulian pengunjung terhadap lingkungan wisata yang dikunjungi sehingga tujuan pengelolaan kawasan taman nasional tercapai, namun Situ Sangiang sebagai bagian Taman Nasional Gunung Ciremai belum memiliki media interpretasi. Penelitian bertujuan mengidentifikasi karakteristik dan preferensi pengunjung terhadap media interpretasi serta merancang media interpretasinya. Penelitian dilakukan pada bulan April 2017. Metode yang digunakan yaitu wawancara dan studi literatur dengan dianalisis secara deskriptif. Mayoritas pengunjung berdasarkan tujuan kunjungannya adalah pengunjung dengan tujuan rekreasi (76%), yang didominasi oleh perempuan dewasa muda (17-25 tahun) dengan durasi kunjungan kurang dari 2 jam. Tujuan religi (16%) didominasi oleh laki-laki dewasa (> 25 tahun) dengan durasi kunjungan 5-10 jam sedangkan tujuan pendidikan (6%) didominasi oleh perempuan dewasa dengan durasi kunjungan >10 jam. Preferensi media interpretasi tujuan rekreasi adalah papan interpretasi, sedangkan tujuan ziarah/religi dan pendidikan adalah interpreter. Media yang direkomendasikan untuk dikembangkan adalah papan interpretasi dengan mempertimbangkan preferensi pengunjung tujuan rekreasi dan keterbatasan sumberdaya di dalam kawasan ini.

Judul: Perencanaan Interpretasi Kawasan Wisata Alam Batuluhur Taman Nasional Gunung Ciremai Kabupaten Kuningan Jawa Barat
Abstrak: Kawasan wisata alam Batuluhur termasuk zona pemanfaatan Taman Nasional Gunung Ciremai. Kegiatan interpretasi perlu dilaksanakan untuk mengatur perilaku pengunjung. Metode yang digunakan adalah studi pustaka untuk memperoleh data kondisi umum kawasan, observasi lapang untuk data potensi kawasan, dan wawancara untuk data preferensi pengunjung dan kelompok sasaran interpretasi. Kegiatan interpretasi yang telah dilakukan berupa kegiatan pengenalan lebah odeng dan camp fire care. Potensi sumberdaya yang terdapat di kawasan yaitu potensi fisik (danau, curug, dll), geologi (batuan dan tambang kapur), biologi (burung elang ular bido, pohon malaka, dll), serta budaya dan sejarah (sejarah Batuluhur, mitos Situ Tespong, dll). Rencana interpretasi yang disusun memiliki tema, “Batuluhur, dengan beragam sumberdaya bermanfaat yang perlu dilestarikan” yang diwujudkan dalam empat program yaitu: Bird watching pada jalur yang mengitari Embung Air; pengenalan pemanfaatan tumbuhan malaka, cuing, dan melinjo; kegiatan interpretasi seni dan budaya masyarakat Padabeunghar; serta kegiatan trekking dan foto hunting pada jalur yang meliputi Bukit Impian, Embung Air, sampai Curug Tespong.

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
