Judul: Pengelolaan parawisata berbasis masyarakat di kawasan wisata pantai Tanjung Karangpusentasi Donggala
Abstrak: Beach tourism area in Tanjung Karang Pusentasi is one of tourism area in the Donggala District, which has diversity and interesting tourism objects. Because of this diversity, the Government of Donggala District has defined the area to become the important area for tourism development. This tourism area is located at the end of the Palu Bay and is directly toward the Makassar Strait, in Tovale, Limboro, Boneoge, and Labuan Bajo villages. To develop this important tourism area, a lot of researches need to be conducted. The objective of this research is to study and develop community based tourism concept, based on: (1) community perception on tourism activity and their expectation of involvement in developing this sector; (2) traditional/local wisdom particularly on natural resources management that can be used as a basis for a community based tourism management; and (3) government concept and other stakeholder views related with community based tourism management.

Judul: Analisis Pengelolaan Lanskap Pesisir Kawasan Pantai Tanjung Karang Sebagai Objek Wisata Bahari di Kabupaten Donggala  Sulawesi Tengah
Abstrak: Kabupaten Donggala memiliki banyak wilayah pesisir, salah satunya Pantai Tanjung Karang sebagai salah satu tempat wisata andalan. Saat ini kegiatan pariwisata cenderung mengutamakan manfaat ekonomi, tanpa memperhatikan daya dukung lingkungan yang ada. Pengelolaan kawasan pesisir merupakan kegiatan pendekatan pengelolaan yang melibatkan dua atau lebih kegiatan ekosistem, sumber daya, dan pemanfaatan guna mencapai pembangunan yang optimal dan berkelanjutan. Tujuan dari penelitian ini adalah untuk mengevaluasi kinerja pemanfaatan dan pengembangan potensi sumber daya pariwisata berdasarkan unit lanskap menggunakan metode Key Performance Indicator (KPI) dan pemetaan hasil penilaian rekomendasi strategi pengelolaan lanskap. Manfaat yang diharapkan dari kegiatan penelitian ini adalah dapat mengetahui penerapan pengelolaan lanskap pesisir Pantai Tanjung Karang yang sesuai dan berkelanjutan. Hasil dari konfirmasi responden tentang aspek-aspek dalam pengelolaan pantai Tanjung Karang yaitu terdapat beberapa atribut belum cukup optimal. Dari hasil evaluasi KPI terdapat 6 atribut yang dievauasi dan diberikan rekomendasi, dari hasil analisis SWOT yang telah dilakukan, didapatkan 8 rekomendasi strategi.

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
