Judul: Pembelajaran (Lesson Learned) Pengembangan Wisata Alam Di Taman Nasional Kepulauan Seribu
Abstrak: Kecenderungan masyarakat perkotaan yang menginginkan wisata berbasis alam dengan biaya terjangkau, akses mudah dan waktu singkat menjadikan TNKpS pilihan tempat wisata. Penelitian ini bertujuan menganalisis faktor-faktor pengembangan wisata alam di TNKpS, kemudian mendeskripsikan lesson learned yang didapat untuk membantu pengembangan wisata alam di taman nasional khusunya di taman nasional laut. Data dikumpulkan dengan menggunakan metode wawancara tidak terstruktur dan kuisioner terbuka, lalu dianalisis secara statistik deskriptif menggunakan panduan kebijakan operasional dalam pengembangan wisata alam menurut PHKA 2003 dan Renstra tahun 2014 BTNKpS. Jenis wisata yang ditawarkan di TNKpS yaitu wisata resort dan wisata pemukiman. Pengelola wisata di TNKpS meliputi kepala resort wisata, agen travel wisata, manajer resort wisata, dan pemda. Terdapat delapan faktor pengembangan wisata yang dilakukan TNKpS yaitu partisipasi dan pemberdayaan masyarakat lokal, manajemen SDA, promosi dan pemasaran, akomodasi, pelayanan, infrastruktur, dukungan finansial pemerintah.

Judul: Perencanaan Lanskap Desa Wisata di Sekitar Resort Gunung Tujuh Taman Nasional Kerinci Seblat Propinsi Jambi
Abstrak: Taman Nasional merupakan kawasan yang memiliki keaneka-ragaman hayati yang tinggi dan mewakili ekosistem darat maupun perairan. Taman Nasional Kerinci Seblat (TNKS) adalah salah satu dari 34 taman nasional yang ada di Indonesia dan dipilih oleh Pemerintah Indonesia sebagai kawasan konservasi, karena taman nasional ini merupakan taman nasional dengan ekosistem darat terluas dan memiliki mamalia kunci (penciri kawasan) terbanyak (43 jenis). Disamping itu, taman nasional ini juga memiliki potensi wisata yang patut dibanggakan dan harus dikembangkan lebih lanjut. Kegiatan magang di TNKS ini adalah salah satu upaya untuk tindakan konservasi kawasan dan pengembangan potensi wisata yang ada di dalamnya. Perencanaan desa wisata untuk desa sekitar kawasan TNKS adalah salah satu bentuk pengembangan yang menunjang pengembangan wisata yang ada di kawasan.

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
