Judul: Kajian Pengembangan Pariwisata Bahari dan Perikanan (dengan Pendekatan Ekologis) di Kawasan Pesisir Anyer, Kota Serang
Abstrak: Penelitian dilakukan di Kecamatan Anyer, Kabupaten Serang, pada bulan Juli- Oktober 2004. Data yang diambil berupa data sekunder dan data primer. Analisa data adalah analisa deskriptif, matriks kesesuaian untuk pariwisata bahari dan pariwisata pantai, persen penutupan karang, analisis persepsi dan preferensi pengunjung dan analisa SWOT. Persen penutupan terumbu karang di Pulau Sangiang mencapai 50-60 % yang menunjukkan kondisi terumbu karang cukup baik. Tipe pantai yang ada di sepanjang Pantai Anyer adalah pantai berpasir dan pantai berbatu. Hasil analisa kualitas air di Pulau Sangiang, Desa Cikoneng, dan Desa Bandulu sesuai dengan baku mutu air laut untuk wisata bahari berdasarkan Keputusan Menteri KLH no.51 tahun 2004. Produksi perikanan tangkap tertinggi tahun 2003 pada bulan September yaitu 15.323 kg dan terendah pada bulan November yaitu 110 kg. Produksi perikanan pada tahun 2004 mengalami penurunan yang besar. Hasil analisa kesesuian kawasan untuk kegiatan pariwisata pantai di sepanjang Pantai Anyer adalah 564 (sangat sesuai) dan Pulau Sangiang 222 (sesuai bersyarat). Hasil analisa kesesuaian kawasan untuk kegiatan pariwisata bahari di Pulau Sangiang adalah 592 (sesuai bersyarat). Isu dan permasalahan yang terjadi di kawasan pesisir Anyer khususnya kegiatan pariwisata dan perikanan adalah degradasi lingkungan, tata ruang wilayah, keterbatasan sarana dan prasarana, keterbatasan informasi dan data penunjang, dan rendahnya kualitas sumberdaya manusia pelaku kegiatan perikanan dan pariwisata. Hasil analisia SWOT menghasilkan tiga strategi yang menjadi prioritas untuk pengembangan kegiatan pariwisata dan perikanan yaitu pertama, mengatasi pelanggaran aturan-aturan, penyediaan data penunjang, dan meningkatkan kualitas sumber daya manusia. Kedua, meningkatkan kunjungan wisatawan. Ketiga, penyediaan sarana dan prasarana perikanan, peningkatan kualitas sumber daya manusia dan produksi hasil perikanan.

Abstrak: Pantai Anyer merupakan salah satu destinasi wisata yang mampu menarik wisatawan untuk berkunjung karena anugerah keindahan alamnya. Pantai Anyer dinobatkan sebagai salah satu destinasi unggulan yang ada di Provinsi Banten yang mendapatkan predikat sebagai Seven Wonders of Banten. Hal ini membuat objek wisata tersebut selalu mengalami peningkatan jumlah kunjungan wisatawan dari tahun ke tahun. Akan tetapi, terdapat kawasan industri yang lokasinya berdekatan dengan wisata Pantai Anyer dan mengancam keberlanjutan objek wisata tersebut. Berdasarkan uraian sebelumnya, tujuan dari penelitian ini yaitu (1) Mengestimasi nilai ekonomi objek wisata Pantai Anyer. (2) Menganalisis status keberlanjutan objek wisata Pantai Anyer. (3) Merumuskan strategi pengembangan objek wisata Pantai Anyer yang berkelanjutan. Metode yang digunakan dalam penelitian ini adalah metode Individual Travel Cost Method, Rapfish, dan Interpretative Structural Modelling. Hasil penelitian menunjukkan bahwa : (1) Nilai ekonomi wisata Pantai Anyer sebesar Rp236.744.853.420,20 per tahun. (2) Status keberlanjutan wisata Pantai Anyer dari keempat dimensi dinyatakan cukup berkelanjutan. (3) Sub-elemen kunci dalam strategi pengembangan wisata adalah meningkatkan partisipasi masyarakat dalam menjaga dan mengembangkan objek wisata pantai, meningkatkan peran stakeholders dalam menjaga dan mengembangkan objek wisata pantai, serta meningkatkan kualitas SDM pengelola wisata dan masyarakat sekitar objek wisata pantai., Anyer Beach is one of the tourist destinations capable of attracting visitors due to its endowment of natural beauty. Anyer Beach has been named one of the top destinations in Banten Province, earning the title of one of the Seven Wonders of Banten. This recognition has led to a continuous increase in visitors to this tourist attraction each year. However, there is an industrial area located near the Anyer Beach tourist site, posing a threat to the sustainability of the tourist destination. Based on the description above, the objectives of this study are (1) To estimate the economic value of the Anyer Beach tourist site. (2) To analyze the sustainability status of the Anyer Beach tourist site. (3) To formulate a sustainable development strategy for the Anyer Beach tourist site. The methods used in this study are the Individual Travel Cost Method, Rapfish, and Interpretative Structural Modelling. The study's results indicate that: (1) The economic value of Anyer Beach tourism is 236,744,853,420.20 IDR per year. (2) The sustainability status of Anyer Beach tourism from the four dimensions is considered fairly sustainable. (3) The key subelements in the tourism development strategy are increasing community participation in maintaining and developing the beach tourist site, enhancing the role of stakeholders in maintaining and developing the beach tourist site, and improving the quality of human resources managing the tourism and the surrounding community of the beach tourist site.

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
