Judul: Persepsi dan Preferensi Pengunjuung terhadap Media Interpretasi di Batu Secret Zoo, Jawa Timur Park 2
Abstrak: Persepsi dan preferensi pengunjung terhadap media interpretasi memengaruhi informasi yang didapatkan oleh pengunjung. Penelitian bertujuan mengidentifikasi karakteristik pengunjung, jenis-jenis media interpretasi, serta menentukan persepsi dan preferensi pengunjung terhadap media interpretasi di Batu Secret Zoo (BSZ), Jawa Timur Park 2. Metode yang digunakan yaitu survei pendahuluan, observasi lapangan, dan wawancara menggunakan kuesioner terhadap 100 pengunjung yang sudah mengelilingi BSZ dan panduan wawancara kepada satu narasumber (pengelola BSZ). Uji chi-square dilakukan untuk menentukan hubungan antara preferensi dengan karakteristik responden. Hasil menunjukkan karakteristik responden didominasi kelas umur 12-16 (41%) dengan tujuan edukasi. Persepsi terhadap media interpretasi signboard sudah relevan (40%) sedangkan preferensi pengunjung yaitu media interpretasi signboard (37%) yang menyajikan status konservasi. Hanya 2% responden yang mendapatkan pengetahuan mengenai kelangkaan, sementara media interpretasi berfungsi sebagai pengenalan status konservasi terutama satwa asli Indonesia. Preferensi media interpretasi tidak berhubungan dengan karakteristik.

Judul: Evaluation of Interpretation Media in the Bogor Botanical Garden
Abstrak: ABSTRAK RIZQI ANISA SUBANDI. Evaluasi Media Interpretasi di Kebun Raya Bogor. Dibimbing oleh EVA RACHMAWATI dan NANDI KOSMARYANDI. Media merupakan salah satu unsur dalam komunikasi. Keberadaan media interpretasi yang dapat dijangkau oleh seluruh pengunjung diharapkan dapat membantu tercapainya tujuan Kebun Raya Bogor (KRB) dalam fungsi pendidikan untuk masyarakat. Penelitian ini bertujuan mengidentifikasi dan menilai papan interpretasi di KRB berdasarkan observasi lapangan, mengidentifikasi karakteristik pengunjung dan persepsinya terhadap papan interpretasi di KRB, dan mengevaluasi papan interpretasi di KRB. Metode yang digunakan adalah survei pendahuluan (studi pustaka, observasi lapangan dan wawancara kepada pihak pengelola KRB), observasi lapangan, penyebaran kuesioner kepada 95 pengunjung, dan panduan wawancara kepada pengelola. Evaluasi papan interpretasi dilakukan berdasarkan tiga kriteria, yaitu tata letak, desain, dan isi materi. Evaluasi papan interpretasi di KRB menunjukkan bahwa seluruh jenis papan telah sesuai sebagai media interpretasi. Namun, masih terdapat beberapa papan yang belum memenuhi kriteria dengan baik sehingga perlu ditingkatkan. Pengembangan terhadap kriteria yang belum sesuai disesuaikan dengan jenis papan interpretasi di KRB.

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
